These reactions involved a condensation reaction of aromatic benzaldehydes, 5,5-dimethyl-1,3-cyclohexanedione, and dicyanomethane in a solvent mixture of ethanol and water, resulting in the desired products in moderate to good yields. The procedure is efficient and eco-friendly, and the products can be easily obtained by recrystallisation. Thus, this protocol offers an alternative to existing methods.

Ebook "Catalysis for alternative energy generation" summarizes the role and the possibilities of catalysis in the production of new energy carriers and in the utilization of different energy sources. The main goal of this work is to go beyond those results discussed in recent literature by identifying new developments that may lead to breakthroughs in the production of alternative energy. The book discusses the use of biomass or biomass derived materials as energy sources, hydrogen formation in methanol and ethanol reforming, biodiesel production, and the utilization of biogases.

The application of raw-starch hydrolysis enzymes to ethanol production by no-cook technology at very high gravity (VHG) (311.5 g/L) from rice would reduce the energy consumption compared to traditional process. In this study, the Taguchi design and the desirability function were used to identify the optimized production process for economic and technological targets.

The sugarcane is one of the most important crops in Brazil, the world´s largest sugar producer and the second largest ethanol producer. The presence of weeds in the sugarcane plantation can cause losses up to 90% of the production, caused by the competition for light, water and nutrients, between the crop and the weeds.

We have carried out studying for antioxidant activity of 58 extracts prepared from vegetables and fruits in Viet Nam by three methods including DPPH and H2O2 scavenging activity assays and determination of total flavonoid content (TFC). Ethanol extract of Tamarind seed (NTBT-17), Grape seed (NTBT-19) and Mangosteen peel (TNB-10) showed high amount of TFC which is 848.8, 655.9 and 422.9 mgQE/100g, respectively.

This thesis documents a research program in which Australian grown Danshen extracts and related bioactive compounds have been demonstrated to be effective in scavenging free radicals, namely ROS generation, in a cell free system and NADPH oxidase derived superoxide (O2-) generation in vascular tissue (rat aorta). Danshen extracts, both aqueous and ethanol, and their active compounds (Tanshinone IIA, Salvianolic Acid B and Danshensu) demonstrated anti-oxidant activity however findings exhibited stronger activity in a cell free system than in the aortic vascular tissue.

In the present study, ethanolic extract of Mesua ferrea L. stamens was investigated for its potential to reverse some features of bronchial asthma in ovalbumin-induced murine model of asthma. Mesua ferrea commonly called nagakeshar (Family, Calophyllaceae) is a well-known antiallergic drug in the Asian folk system of medicines. In the present work, pharmacological studies are done to provide scientific evidence for therapeutic potential of plants in allergic asthma.

In recent decades, the frequency of flooding is increasing with the change of global climate. Flooding has become one of the major abiotic stresses that seriously affect growth and development of plants. Triarrhena sacchariflora Nakai has been considered a promising energy crop for utilization in ethanol production.

Dried distillers’ grain (DDG) from rice-based alcohol factories contains relatively high protein (ca. 79% of dry matter). However, this vegetative protein source has only been used for animal feeding. To enhance the value of this by-product, i.e. toward application for the food industry, this study has applied different approaches for the enrichment of protein content in this by-products.

Lignocellulosic biomass is a potential material source for ethanol production. Particularly, the sugarcane bagasse (SCB) coming from the sugar waste of the refinery is very rich in lignocellulose that can be biochemically transformed into ethanol. However, its recalcitrant structure necessitates a pretreatment step to break up the lignocellulosic matrix, thus improving the accessibility of hydrolytic enzymes to carbohydrates for sugar production.

An efficient 2-component synthesis of a series of 3-(2-(substituted phenylamino)thiazol-4-yl)-2H -chromen-2- ones (3a–j) was achieved by the reaction of 3-(2-thiocyanatoacetyl)-2H -chromen-2-one (1) with a variety of suitably substituted anilines in 1:1 molar ratio in ethanol. The structures of the products were established by elemental analyses, and UV-vis, FTIR, 1H and 13C NMR, and mass spectroscopy. 3-(2-(4-Methylphenylamino)thiazol-4-yl)-2 H -chromen-2- one (3j) was further characterized by single crystal X-ray diffraction study.

In this paper, synthesis of tetrakis(carboxyphenyl)porphyrin (TCPP) coated cadmium ferrite (CdFe 2 O4) nanoparticles by using L-lysine as an anchor is reported for the first time. The ferrimagnetic CdFe 2 O4 nanoparticles were prepared via the facile self-assembly method of reflux followed by a heating treatment. The obtained magnetic nanoparticles were coated with TCPP in the presence of the amino acid L-lysine by sonication in ethanol and then refluxing for 12 h. The structural characteristics of the products were determined using FT-IR and XRD pattern.

The synthesis of novel, symmetrical, tetrasubstituted metallophthalocyanines (cobalt, zinc, and copper) bearing four 2-{[2-(dimethylamino)ethyl](methyl)amino} ethoxy units was reported. The dinitrile derivative was converted into the water-soluble quaternized product by its reaction with methyl iodide. The quaternized zinc phthalocyanine was obtained from the reaction of the water-soluble dinitrile derivative with zinc acetate. The structures of the newly synthesized molecules were proposed according to elemental analysis, 1 H NMR, FT-IR, and UV-Vis spectral data.

CeO2 nanoparticles were used as an efficient catalyst for the preparation of cyclic β-aminoesters by threecomponent reaction between primary amines, ethyl acetoacetate, and chalcones in ethanol. Atom economy, low catalyst loading, reusable catalyst, and high yields of products are some of the important features of this protocol.

The degree of DNA depolymerization, qualitative and quantitative composition of protein and lipid components of the obtained preparations determined the possibility of their use as medical drugs. The method of obtaining the target product with the use of salt extraction and ethanol precipitation was supplemented by proteolysis in order to remove residual protein to a value of no more than 5% of dry weight.
