The purpose of this research is to study the processing of waste from coffee industry by hydrolysis in subcritical water to produce sugars that can be subsequently fermented to obtain second generation ethanol. A semi-continuous process was used, at temperatures of 150, 175, 200 and 250 °C, pressure of 22.5 MPa and water flow rate of 10 mL/min. The content of total reducing sugars and composition were analyzed before and after the subcritical water hydrolysis. The best results for coffee powder were 9 g total reducing sugars (TRS)/100 g (w.b.) raw material, at 150 °C and 22.5 MPa. As temperature increased TRS yield decreased due to degradation. There was low yield of fermentable sugars from green coffee powder. Glucose and cellobiose were found, while arabinose and xylose were not detected. As the temperature of the hydrolysis process increased, the amount of fermentable sugars recovered decreased, which is possibly due to sugars degradation.

Polyhydroquinolines are fused heterocyclic compounds which exhibits bactericidal, fungicidal, analgestic and anti-inflammatory activities and act as hypotensive and anticancer agents. Due to their biological importance, there has been considerable interest in developing new synthetic methods for the preparation of polyhydriquinolines. Herein as a part of our efforts to develop new synthetic method in heterocyclic chemistry, we report an environmentally benign, efficient and convenient protocol for the synthesis of derivatives of polyhydroquinoline by combining dimedone, ethylacetoacetate and ammonium acetate with various substituted arylaldehydes in good to excellent yields by a grinding method under solvent-free conditions. The process is simple, straightforward, environmentally benign and easily leads to the synthesis of desired polyhydroquinolines i.e ethyl 4-phenyl-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexahydro-quinoline-3-carboxylate. The catalyst is easily available and inexpensive. This method proves to be advantageous in terms of excellent yields and short reaction times. In recent years, with the emphasis on adoption of cleaner green chemistry processes, a tremendous interest has been observed in carrying out various chemical transformations under heterogenous conditions owing to simplicity in operation. Among phase transfer catalysts, TEBAC (triethylbenzylammoniumchloride) has gained immense popularity in organic synthesis in last few decades. Owing to all the advantages of TEBAC, the development of TEBAC catalysed organic reactions is still an attractive research area in the coming future.

Maelle Derrien is currently a PhD student in Food Science at the University Laval in Québec, Canada. She has obtained a degree in Biology and Biochemistry from University of Rennes, France.

Green chemistry is a major challenge of the 21st century. Industrial vegetable by-products contain high levels of valuable phytochemicals that can be used as a rich source of biomolecules. The main objective of this project was to develop an extraction process technology of two highly valuables biomolecules, lutein and chlorophyll, using spinach by-products and respecting the main principles of green chemistry. This work focused on the development and optimization of ecological processes for extraction of these phytochemicals, using supercritical CO2 technique and response surface methodology (Box Behnken). The extraction efficiency has been compared to the total extraction of lutein and chlorophyll obtained with hexane. The effect of pressure, temperature, duration and co-solvent has been tested on the extraction of lutein and chlorophyll. The results suggested that the extraction was mostly influenced by the extraction time, pressure and ratio of cosolvant (ethanol). There is a linear and negative quadratique effect of the pressure and the extraction time on the lutein and chlorophyll whereas the cosolvant exerted a linear positive effect on the recovery of both biomolecules. The temperature did not exert a significant interaction on these molecules during the extraction procedure. The optimum extraction parameters were given by a desirability function, and were 3,6h at 490 bars, with 10% of cosolvent and at 56 °C. With these parameters a yield of 65% lutein and 45% of chlorophyll, without major drawbacks were obtained. The supercritical fluid extraction is therefore the available method for extracting lutein and chlorophyll with respecting to the green chemistry standard.

Hua Deng has completed his PhD in Environmental Science from Research Center for Eco-Environmental Sciences (RCEES), Chinese Academy of Sciences (CAS) in 2015. He has been working as assistant professor in Institute of Urban Environment (IUE), Chinese Academy of Sciences (CAS) since 2015. His research interests include environmental catalysis and air pollution control, such as selective catalytic reduction of NOx and catalytic combusion of VOCs.

NOx removal from lean-burn exhaust remains a major challenge in environmental catalysis. Selective catalytic reduction of NOx by hydrocarbons (HC-SCR) is a potential method to remove NOx from lean-burn exhausts. The alumina supported silver catalyst (Ag/Al2O3) is deemed as one of the most effective materials for HC-SCR of NOx in excess oxygen. In particular, ethanol is extremely effective for the SCR of NOx over Ag/Al2O3. However, it is lack of activity in the low temperature range (< 350 ℃) still remains a problem. Since pioneer work of Burch et al, preparing a new type of Ag/Al2O3 catalyst to improve its low temperature performance by solvent-free mechanochemically method draw widely interest. In former study, the detailed preparing conditions including rotation speed and ball-milled time were carefully examined. The performance of selective reduction of NOx was evaluated by ethanol accompanied with byproduct monitor. A strongly positive correlation between the amount of Altetra structures and N2 production rate confirms the crucial role of Altetra in NOx reduction by ethanol. Thus, oriented designing and creating active site of HC-SCR( namely Ag-O-Altetra entity) at micro-scale in Ag/Al2O3 is promising to improve the conversion activity at low termperatures. In this study, AlN was used as precursor of Altetra entities to anchor isolated silver ions. After water thermal calcination of Ag/Al2O3 with AlN addition, the low temperature activity is truely improved. The catalytic performance of this catalysts is close to the H2 effect.

DFT investigations are carried out to explore the effective catalyst forms of DBU and H2O and the mechanism for the formation of 2,3-dihydropyrido[2,3-d]-pyrimidin-4(1H)-ones. Three main pathways are disclosed under unassisted, water-catalyzed, DBU and water cocatalyzed conditions, which involves concerted nucleophilic addition and H-transfer, concerted intramolecular cyclization and H-transfer, and Dimroth rearrangement to form the product. The results indicated that the DBU and water cocatalyzed pathway is the most favoured one as compared to the rest two pathways. The water donates one H to DBU and accepts H from 2-amino-nicotinonitrile (1), forming [DBU-H]+-H2O as effective catalyst form in the proton migration transition state rather than [DBU-H]+∙OH-. The hydrogen bond between [DBU-H]+•••H2O•••1- decreases the activation barrier of the rate-determining step. Our calculated results open a new insight for the green catalyst model of DBU-H2O.

Antibiotics have been the most effective therapeutic agents against infectious diseases caused by bacterial pathogens. However, antibiotics-resistant pathogens are increasingly prevalent, posing a serious threat to global public health. Therefore, this study aimed at determining the potency of 3-methlyquinoxaline-2-hydrazone derivatives against panel of pathogens associated with human diseases. The antibacterial potential of the synthesized compounds 2׳-12׳ was determined using agar well diffusion method. The minimum inhibitory concentrations and minimum bactericidal concentrations of the synthesized compounds were determined along with the rate of kill. Protein leakage from cells of Enterococcus faecalis and Pseudomonas fluorescence was also determined. The synthesized compounds 2׳-12׳ exhibited varying degree of antibacterial activity. The MIC exhibited by the synthesized compounds against susceptible Gram positive and Gram-negative bacterial isolates ranged between 0.0625 and 0.0313 mg/mL and 0.125 and 0.0625 mg/mL respectively. The time-kill assay revealed that the percentage of cells killed increased with the concentrations of the synthesized compounds as well as contact time interval. A 100% percent kill of Enterococcus faecalis was achieved by compound 5 at 2 x MIC within 90 minutes. Varying amount of protein was leaked by the compounds from selected test isolates leading to their death. In conclusion, 3-methlyquinoxaline-2-hydrazone derivatives exhibited appreciable antimicrobial activities at low concentration and minimal contact time. The 3-methlyquinoxaline-2-hydrazone derivatives may serve as a potent antimicrobial agents to combat the development of multiple resistance by the pathogens against available antimicrobial agents.

Nickel (Ni) and zinc oxide (ZnO) nanoparticles encapsulated in carbon-shell (Ni-ZnO)@C have been prepared for photocatalytic formation of valuable C1-C2 chemicals from CO2 and H2O. The (Ni-ZnO)@C nanoparticles having the Zn/Ni atomic ratios of 1-3 were synthesized by carbonization of Ni2+- and Zn2+-β-cyclodextrin at 573 K for two hours. Their component fitted XANES spectra indicate that nano Ni and ZnO are the main species in the (Ni-ZnO)@C. To increase the collision frequency of reactants (H2O and CO2) with the active sites (Ni and ZnO) within the carbon-shell, Ni and ZnO are partially etched from the (Ni-ZnO)@C with a H2SO4 solution (2 N). By XRD and TEM, the sizes of the Ni and ZnO in (Ni-ZnO)@C are between 7-30 nm in diameter. Under the UV/Vis irradiation for five hours, yields of formic and acetic acids from the photocatalytic reduction of CO2 and H2O in the (Ni-ZnO)@C nanoreactors are 37.9 and 12.5 μmol/g-hr, respectively. It seems that ZnO involves in photocatalytic splitting of H2O, and provides hydrogen for catalytic hydrogenation of CO2 on Ni to yield formic and acetic acids.

Zhihua Lian has completed his PhD in Environmental Science at the age of 27 years in 2015 from Reseach Center for Eco-Environmental Sciences, Chinese Academy of Sciences. She has published 5 SCI papers in reputed journals as the first author.

Nitrogen oxides have been a major source of air pollution, causing environmentally harmful problems such as photochemical smog, acid rain, ozone depletion and greenhouse effects [1]. Selective catalytic reduction of NOx with NH3 (NH3-SCR) has been used extensively for the removal of NOx, and the most widely used catalyst is V2O5-WO3(MoO3)/TiO2 [2]. However, some problems still remain, such as the narrow operating temperature window of 300-400 oC, low N2 selectivity at high temperatures [3]. Therefore, it is necessary to develop highly efficient low temperature SCR catalyst. In our previous study [4], we have developed a Nb-VOx/CeO2 catalyst, prepared by a homogeneous precipitation method, showing better NH3-SCR activity than VOx/CeO2 catalyst. In this study, stronger resistance to H2O and SO2 over Nb-VOx/CeO2 catalyst than VOx/CeO2 was observed. When 5 vol.% H2O was introduced to the inlet gas at 250 oC, the NOx conversion over VOx/CeO2 decrease rapidly from 92% to 56%, while 100% NOx conversion over Nb-VOx/CeO2 catalyst was maintained all the time in the test. When 100 ppm SO2 was introduced to the inlet gas at 250 oC, the NOx conversion over VOx/CeO2 decreased from 95% to 24% in 48 h and could not recover to the initial activity after the removal of SO2, while nearly 90% NOx conversion over Nb-VOx/CeO2 was obtained. The modification of Nb to VOx/CeO2 inhibited the formation of sulfate on the catalyst surface, resulting in the improvement of SO2 tolerance.

A simple, quick and efficient method for fabrication of magnetic multi-wall carbon nanotube-TiO2 (MMWCNT-TiO2) nanocomposite through electrostatic attraction was proposed as a novel method. First of all, TiO2 nanoparticle was synthesized by atmospheric pressure chemical vapor synthesis (APCVS) method and characterized by scanning electron microscopy (SEM), x-ray diffraction (XRD) and UV–vis diffuse reflectance spectra (DRS). The magnetic multi-wall carbon nanotube (MMWCNT) composite was prepared. Finally, TiO2 nanoparticle was coated onto the surface of the MMWCNT through electrostatic attraction in ethanol solution. The morphology and structure of the final composite were investigated by SEM, XRD, Energy dispersive x-ray spectrometry (EDS) and fourier transform infrared spectrophotometer (FT-IR). Both TiO2 and MMWCNT-TiO2 were characterized by BET surface area/pore volume analysis. The photocatalytic function of the TiO2 and MMWCNT-TiO2 composite was validated for malachite green (MG) degradation under irradiation of ultra violet (UV) light. MMWCNT-TiO2, adsorbing MG, was easily separated from the aqueous solutions with the help of an external magnet; so, no filtration or centrifugation was necessary. The effects of pH, irradiation time, catalyst concentration, MG concentration, etc. on the photocatalytic activity were studied. The optimal conditions were an initial MG concentration of 20 mg L-1 at pH 5.0 with catalyst concentration of 0.2 g L-1 under UV irradiation for 240 min with good recyclisation of MMWCNT-TiO2 catalyst.

Experimental and theoretical electron densities in 2-thiocoumarin have been analyzed based on the X-ray diffraction data at 90 K. These compound pack in the crystal lattice with weak C-H…O and C-H….π interactions, and variations in charge density properties and derived local energy densities have been investigated in the regions of intermolecular interactions. Theoretical charge density calculations on crystals using the B3LYP/6-311++G(d,p) method show remarkable agreement with the derived properties and energy densities from the experiment. The intermolecular interactions follow an exponential dependence of electron density and energy densities at the bond critical points. The Laplacian follows a “Morse-like” dependence on the length of the interaction line. Based on the set of criteria defined using the theory of “atoms in molecules”, it has become possible to distinguish between a hydrogen bond (C-H…O) and a van der Waals interaction (C-H….π). This has resulted in the identification of a “region of overlap” in terms of electron densities, energy densities, and mutual penetration of the hydrogen and acceptor atoms with respect to the interaction length. This approach suggests a possible tool to distinguish between the two types of interactions. High field indicates that this molecule exhibit considerable electrical conductivity in atomic charges.The ESP map is found to be positive throughout the backbone of the molecule. The negative charges have a tendency to drift from left to right. Thermodynamic parameters like heat capacities (Cºp,m), entropies (Sºm) and enthalpies changes (Hºm) are used for various electrical field. Theoretical FT-IR and FT-Raman spectra of the title molecule have been constructed which show good agreement with recorded spectra.

Benzoxazoles are a large chemical family used as antimicrobial agents against a wide spectrum of microorganisms. The high therapeutic activity of the related drugs has encouraged the medicinal chemists to synthesize a large number of novel chemotherapeutic agents. The reaction of 2-aminophenol and p-amino benzoic acid yielded 2-(4-aminophenyl)benzoxazole in the presence of polyphosphoric acid which was further condensed with different aromatic aldehydes offered Schiff bases. The compounds were synthesized in good yield and the chemical structures of the compounds were elucidated by their TLC, IR and 1HNMR. Their antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and antifungal activity against Aspergillus niger, Candida albicans were investigated. The results showed that all of the newly synthesized compounds (G-2- to G-8) have exhibited significant antimicrobial activity.

We estimated the bioavailable fraction of metals (Zn, Cu, Cd, Mn, Pb, Ni, Fe, and Cr) in sediments of the Huelva estuary and its littoral of influence by carrying out the most popular methods of sequential extraction (BCR and Tessier) and a biomimetic approach (extraction with protease K) and compared the results obtained with enrichments factors found in Arenicola marina. The linear correlation coefficients (R2) obtained between the fraction mobilized by the first step of the BCR sequential extraction, by the sum of the first and second steps of the Tessier sequential extraction, and by protease K, and enrichment factors in Arenicola marina, are at their highest for protease K extraction (0.709), followed by BCR first step (0.507) and the sum of the first and second steps of Tessier (0.465). This observation suggests that protease K represents the bioavailable fraction more reliably than traditional methods (BCR and Tessier), which have a similar ability.

Nowdays main emphasis is being laid on the adoption of cleaner, safer and environmentally benign reaction conditions avoiding the use of flammable, volatile and toxic solvents for carrying out various chemical transformations. C-C bond formation via condensation of active methylene containing compounds with aromatic aldehydes is a reaction of great significance in organic synthesis. In this context the choice of aqueous medium for carrying out organic reactions consumes great significance as water plays important role in biological processes as well as a medium in organic reactions which proves to be more advantageous than those in organic solvent. Therefore, switching from organic media to aqueous media as a reaction medium is a challenging and attractive task for synthetic organic chemists. Catalyst plays a significant role in chemical industry and has a major impact on quality of human life and also its development. Among the popular reported heterogenous catalyst, Zirconyl chloride has gained the immense popularity in organic synthesis because of its recyclability, inertness, thermal stability and ease of separation from the reaction mixture.It is very attractive catalyst as it could be easily recycled via simple filtration technique. Its excellent catalytic activity can be observed over a vast array of acid catalysed organic transformations and synthesis of various organic compounds. In course of development of green methodologies for synthesis of heterocyclic compounds having biological activity, herein we attempted for an efficient and high yielding synthesis of various substituted tetraketones i.e 2,2’-aryl-methylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one) from an arylaldehyde and dimedone in 2:1 ratio in aqueous medium in the presence of zirconyl chloride. These compounds were identified on the basis of spectral analysis and by comparison with authentic samples. In the present investigation the use of any toxic and hazardous chemicals during any stage of reaction has been avoided and it meets our requirements of reaction conditions, reaction times and yields.

Green chemistry encourages the development of innovative processes combining bio renewable, sustainable resources with non-hazardous, minimal energy and waste generating transformations in order to produce useful chemical products. 2,3-Butanediol is a commodity chemical with a wide range of applications as a precursor to plastics and pesticides. Although industrially, 2,3-butanediol is prepared by hydrolysis of 2,3-butene oxide, optically pure (2R,3R)-butanediol is produced by a range of microorganisms and large scale fermentation processes that were first investigated during the 1940s. More recent developments have shown that 2,3-butanediol can be synthesised by fermentation from industrial waste carbon monoxide using clostridium bacteria. However, a challenge with the fermentation processes here is that recovery of the diol (bp 177 °C) from water either by solvent extraction or by distillation can be wasteful, energy intensive, costly and environmentally damaging. Here we describe the potential that in-situ trans-esterification of 2,3-butanediol with dimethyl carbonate to produce butylene carbonate can make to the value of the end product and to the overall extraction process.

Cosmetic ingredients constitute a diverse group of chemicals that have recently been recognized as particular contaminants of the aquatic environment. Galaxolide is one of the components that perfume and cologne manufacturers use to add it to musk-scented colognes. Galaxolide does not break down easily in the environment and it is extremely toxic to aquatic animals that makes it that it is kept out of ground and surface water. In this study, a cheap and reliable hydrothermal method was applied to synthesize polyvinylpyrrolidone coated magnetite nanoparticles to separate Galaxolide from aqueous solutions. Based on gas chromatography−mass spectrometry data, approximately 99.4% of Galaxolide was removed within 20 min of magnetic separation. Results showed that these nanoparticles could be utilized to remove Galaxolide over a short time with a high removal efficiency under environmentally friendly conditions. In addition, regeneration of the adsorbent performed with NaOH and results showed that NaOH was efficient to regenerate the adsorbent. Repeating the experiments with the regenerated polymer showed 87% removal efficiency. It is therefore concluded that the coated polymer on magnetite nanoparticles is a sustainable and reliable method to remove Galaxolide from water.

In this study we investigated the antiproliferative activity of four plant extracts on SH-SY5Y human neuroblastoma cell line (including both adherent and floating cells) using the method of real-time monitoring of cell growth (impedance measurements). SH-SY5Y cells were grown in direct contact with gold electrodes integrated to the bottom surface of microtiter plate well. Cells were incubated with 6 concentrations of each plant extract 24h after the cells were seeded. Low intensity AC signals (µA) were periodically applied to electrodes and the magnitude of electric impedance was measured. The impedance changes were reflecting the overall interaction of the cells with the electrodes including when various compounds modified cellular features like cell metabolism and capacity of proliferation (the cell growth was evaluated for 72h). The four plant extracts containing 5 mg total phenols, expressed as gallic acid equivalents [GAE], per 1 mL sample, were: GE (Geranium robertianum), EP (Epilobium hirsutum), FG (Fagus sylvatica), JG (Juglans regia). The extracts of 0.5, 5, 10 μg GAE/mL showed no antiproliferative effect, while at higher concentrations (20, 30, 40 μg GAE/mL) of extracts the cellular growth decreased rapidly. We found the 10 μg GAE/mL extract was the concentration for which the antiproliferative effect of extracts on SH-SY5Y become significant. This concentration will be used for further studies to evaluate the antitumor effect of combinations of extracts with cytostatic agents (mixtures with potentiated activity). Our results represent the first evidence of anticancer activity of the four extracts using a method of real-time monitoring of cellular growth.

A newly isolated Yarrowia lipolytica ISF7 strain with a unique adsorption capacity was used as adsorbent for the rapid removal of malachite green from the aqueous solution. The impact of operating parameters such as initial pH, dye concentration, temperature and time added on the MG biosorption were well studied and optimized using response surface methodology, a total of 32 experimental runs were set and the experimental data fitted to the empirical second-order polynomial model of a suitable degree. The optimized biosorption parameters were determined as initial pH 7.0, temperature 25 ºC, 24 h and 35 mg L-1 of MG concentration. The experimental values are in good agreement with predicted values. Analysis of variance show high coefficient of determination (R2 ≥ 0.985) and significant quadratic model was obtained. Results of the statistical analysis confirm the significant (P < 0.05) linear effect was obtained for pH, temperature and time, while only the interaction effect between temperature and time was significant (P < 0.05). The nature of biomass dye interactions was evaluated by FTIR analysis and maximum MG removal (99.889%) was obtained under optimum conditions. The results revealed that Yarrowia lipolytica ISF7 could be used as a low-cost and effective biosorbent for MG removal from aqueous solutions.
