Crystal Growth and Design | Year: 2017
The aim of the present study is to understand and analyze the factors that are influencing CK2 ligands and the role of crystal waters. The influence of the crystal waters on the stability of the ligand was deliberated based on the results of interaction energy and two body interaction energy analyses at M062X/def2-QZVP level of theory. The two body interaction energy analyses was carried out to assess whether important waters were contributing to favorable binding of the ligand through hinge region, where it acts as a bridge in linking protein with ligand or having interaction with ligand alone or merely specific polar interactions. Among the halogen ligands 1ZOH and 1ZOE are observed with the highest interaction energy of -13.96 and -13.75 kcal/mol. This is owing to the interaction of four crystal waters in the above ligands. Among the non-halogen ligands, 2ZJW is observed to be more stable with a huge interaction energy of -42.9 kcal/mol. Tetrabromobenzotriazole derivatives of halogen ligands 5CQU and 3KXM are observed with the highest volume of 294.23 and 266.75 cm3/mol, respectively. The Potential energy surface scan for 3NGA, 2ZJW, and 1ZOH discloses the fact that the shorter distance in the X-ray crystal is reliable, owing to the strong interaction. The natural bond orbital analysis reveals that the hydrogen/halogen bonds forming interaction with water molecules are found to have reasonable energy, but only those hydrogen/halogen bonds with shorter distance have large stabilization energy. © 2017 American Chemical Society.

New formulations of novel polyurethanes based on cardanol-formaldehyde resins, commercial polypropylene glycols and two different aliphatic diisocyanates are reported. Cardanol based novolac type phenolic resin has been condensed with hexamethylene diisocyanate/ isophorone diisocyanate to produce rigid polyurethanes. Tough polyurethanes have been produced by condensing the commercially available polyols viz., polypropylene glycol-1200(PPG-1200) and polypropylene glycol-2000 (PPG-2000) with the above system. The ageing performance of the newly developed polyurethanes has been studied. These studies revealed better hydrolytic, chemical and environmental resistance of rigid polyurethanes and also the high performance character of the isophorone diisocyanate based polyurethanes with respect to their ageing conditions.

Chlorella vulgaris MSU 01 strain isolated from the sediment of the pond is able to produce molecular hydrogen in a clean way. To relate the dynamic coupling between the cultural conditions and biological responses, an original lab scale set up has been developed for hydrogen production. Different sources like mannitol, glucose, alanine, citric acid, aspartic acid, l-alanine, l-cysteine, sodium succinate and sodium pyruvate were used for algal media optimization. Corn stalk, from 1 to 5g/L was tested for the effective algal growth and hydrogen production. The cell concentration of 1.6-19g/L dry cell weight (DCW) was found at the 10th day. The kinetic parameters involved in the hydrogen production at 4g/L corn stalk using the algal inoculum (50mL) in the bioreactor volume (500mL) was found to be with the hydrogen production potential (P s) of 7.784mL and production yield of (P r) 5.534mL respectively. The growth profile of the algal biomass at the above mentioned condition expressed the logistic model with R 2 0.9988. The final pH of the broth was increased from 7.0 to 8.5-8.7. The anaerobic fermentation by C. vulgaris MSU 01 strain involved in the conversion process of complex carbon source has increased the H 2 evolution rate and higher butyrate concentration in the fermentate. © 2010.

Hormones, antibiotics, vitamins and several other chemicals have been tested in aquaculture operations for various remedies. Even though they give positive effects, they cannot be recommended due to their residual and other side effects. The alternative herbal bio-medicinal products in the aquacultural operations, that have the characteristics of growth promoting ability and tonic to improve the immune system, act as appetite stimulators. They increase consumption, induce maturation, and have antimicrobial capability and also antistress characteristics that will be of immense use in the culture of shrimps and other fin fishes without any environmental and hazardous problems. Herbal compounds such as phenolics, polyphenols, alkaloids, quinones, terpenoids, lectines and polypeptides have been shown to be very effective alternatives to antibiotics and other synthetic compounds. The present paper is presented after a careful review of more than 50 herbal plants for their biological effects such as growth promotion, immunostimulation, antistress, antibacterial, antifungal, antivirals, appetite stimulators and aphrodisiac. © Springer Science+Business Media B.V. 2009.

IET Information Security | Year: 2014
In wireless sensor networks (WSNs), the current cluster-based data aggregation technique consumes more energy. Also the secured data transmission are vital for enhancing the data authentication and confidentiality. In order to overcome these issues, in this study, the authors propose a genetically derived secure cluster-based data aggregation in WSN. Initially the cluster heads are selected based on the node connectivity, which acts as a data aggregator. Then, the clustering process is executed using the genetic algorithm. When a cluster member wants to transmit the data to aggregator, a data encryption technique are utilised that offers authenticity, confidentiality and integrity. By simulation results, the authors show that the proposed technique minimises the energy consumption, ensures data security and reduces the transmission overhead. © 2013 The Institution of Engineering and Technology.

Dye pollution in aquatic nature produce serious environmental effects. In this investigation, mesoporous aluminophosphate molecular sieve synthesized and applied for the removal of hazardous dyes Malachite green (MG) and Methylene blue (MB). In the synthesis of mesoporous aluminophosphate (AlPO4) molecular sieve, the structure-directing agent, long-chain alkylbenzene has been used as a template. The template used for the synthesis of mesoporous material is environmentally biodegradable. The mesoporous AlPO4 was synthesized by the absence of an organic base, tetramethyl ammonium hydroxide (TMAOH) which is necessary to maintain the pH for the conventional AlPO4 synthesis methods. The synthesized mesoporous AlPO4 has high thermal stability up to 1173K and large porosity nature (40nm). It was confirmed by the characterization techniques such as low-angle XRD, FT-IR, TGA and BET surface area analysis. The morphology of the material was explained by using SEM and TEM. The hazardous dyes MG and MB removal studied under the various conditions like contact time, dye concentration, temperature, pH and adsorbent dosage to examine the adsorption characteristics of the newly synthesized mesoporous AlPO4 molecular sieves. © 2012 Elsevier B.V.

Stalk of corn (Zea mays L.), a commonly available crop residue in tropical and subtropical countries and found in plenty. In this study, we demonstrated that the pretreated corn stalk waste could be used to produce hydrogen. The isolated Bacillus licheniformis MSU AGM 2 strain (HM214759) from the pretreated paper mill effluent produced hydrogen under optimized conditions: carbon source (1 g/l), nitrogen source (12.5 g/l), temperature (35 °C) and pH (6.0). Alkaline pretreatment with 2% NaOH removed lignin by 48% from the corn stalk waste. Pretreated corn stalk ranges from 1 to 5 g/l were tested for the effective bacterial growth and hydrogen production. Kinetic parameters analyzed in 1 l bioreactor showed the maximum hydrogen production and hydrogen yield with 185 ml/l and 82.5 ml/g substrate, respectively. Growth profile and modified Gompertz model at the above mentioned condition fitted well (R 2, 0.93). Hence the anaerobic fermentation by the isolated strain had increased the hydrogen evolution rate with formic acid, acetate and butyrate concentrations at the end of the fermentation. © 2012.

Effluents releasing from dyeing industries directly affect the soil, water, plant and human life. Among these dyes, plant poisoning, soil polluting and water polluting nature of organic dyes are not yet identified. The plant poisoning and non-poisoning organic dyes are identified through adsorption mechanism of cationic malachite green (MG) and anionic methyl orange (MO) on brinjal plant root powder (cellulose). The positive ΔHo (44kJmol-1) of MG higher than 40kJmol-1 confirmed the adsorption of MG on cellulose is chemisorption and the negative ΔHo (-11kJmol-1) less than 40kJmol-1 showed that the adsorption of MO on cellulose is physisorption. The ΔGo values for the adsorption of MG and MO on BPR are not much increased with increase of temperature which indicated that the adsorption is independent of the temperature. The entropy change for the adsorption of MG and MO has proved that the MG (+ΔSo) has less disorder at the adsorption interface and MO (-ΔSo) has the high disorder at the adsorption interface. The recovery of both dyes has been studied in water at 80 °C on BPR surface and observed that the MO recovery is 95% and MG is 10%. The poor desorption of MG is due to the strong chemisorption on BPR (cellulose) surface proves its plant poisoning nature. The high recovery of MO due to physisorption mechanism proves that MO is not poisoning the plant. © 2011 Elsevier B.V.
