Palladium-Catalyzed Oxidative C–h Alkoxycarbonylation of Arenes with Alkylcarbazates Directed by N-Heterocyclic Substituents

With alkyl carbazates as the green ester source, a novel palladium-catalyzed oxidative free radical carbonylative transformation of the C–H bond on aromatic rings to produce esters has been developed. Good yields of the corresponding products have been obtained with wide functional group tolerance and excellent regioselectivity. A variety of alkyl carbazates are found to be suitable reactants for the ortho-alkoxycarbonylation on the aromatic ring. We report an environmentally benign protocol for the C–H alkoxycarbonylation of arenes with alkylcarbazates directed by N-heterocyclic substituents. Pd(OAc)2 is used to catalyze this oxidative free radical carbonylative transformation. The reaction is tolerant to a wide variety of functional groups to give the products in good yields and excellent regioselectivity

Compressed Biogas (cbg) as an Alternative and Sustainable Energy Source in India: Case Study on Implementation Frameworks and Challenges

Biogas is environment friendly and socially accepted renewable energy source but due to composition quality it is not technically feasible and economically viable at large scale. Biogas conditioning results in upgraded biogas (biomethane) after compression, this compressed biogas (CBG) becomes a complete substitute for fossil fuels and acts as a sustainable energy source. With the calorific value of 52,000 KJ/Kg, CBG is advantageous for energy conservation, reduces the pressure of natural fossil fuel consumption and protects ecological resources. Versatile applications of CBG for generating electricity, heat, and vehicle fuel along with economic and environmental benefits make it the fuel of the future. Despite government support, availability of feedstock and favorable climate conditions for biogas production, the total production volume of CBG is still relatively low as compared to the estimated potential of 62 million tonnes per annum. This study is the first attempt to identify challenges that are hindering the success of Compressed biogas in India, based on exhaustive literature review and in-depth interviews with directors & managers of sustainably running CBG plants. The findings of the study are used in designing an implementation framework that will guide new entrepreneurs, policymakers, plant constructors and other stakeholders for sustainable operation of CBG plants

Observation of Linear Magneto-Resistance with Small Cross-Over Field at Room Temperature in Bismuth

We report the observation of linear magneto-resistance (LMR) with a very low cross-over magnetic field (Bc) at room temperature in bismuth(110) thin films fabricated using thermal evaporation. The magneto-resistance at different temperatures (T) indicate that Bc has a strong T-dependence, and displays a remarkably small magnitude of 180 mT at T = 300 K. The parameter Φ, defined as the MR% (B = 1 T)/ Bc is 248, is considerably higher at room temperature compared to values previously reported in literature. The observed LMR is likely due to the recombination of carriers in compensated systems near charge neutrality. Our measurements demonstrate that the LMR can be observed at a very low field and high T, which can be utilized in a variety of applications

Comparative Performance Analysis of Indirect Vector Controlled Induction Motor Drive Using Optimized AI Techniques

This paper exhibits a point by point comparison between Neuro Fuzzy and Genetic Algorithm GA based control systems of Induction Motor drive, underlining favorable circumstances and drawbacks. Industries are advancing and upgrading generation line to enhance efficiency and quality. Induction machines are considered by nonlinear, time varying dynamics, inaccessibility of few states and thus can be considered as a challenging issue. In this paper, a novel method using modified GA is presented to limit electric losses of Induction Motor and it is compared with Neuro Fuzzy Controller. GA is a subordinate of AI, whose principle relies upon Darwin’s theory—struggle for existence and the survival of the fittest. The technique for deciding the gain parameters of PI controller utilizing GA whose output is utilized to control the torque applied to the Induction Motor in this way controlling its speed. The gains of PI controller are improved with the assistance of GA to upgrade the performance of IM drive. The results are simulated in MATLAB Simulink and are related with the conventional PI controller and Adaptive Neuro Fuzzy controller (NFC). NFC is less complicated and gives great speed precision yet GA based PI controller produces significantly reduced torque and speed ripples compared with other controllers, in this way limiting losses in IM drives

Molecular Interaction Studies of Zinc Sulphide Nanoparticles with DNA and its Consequence: A Multitechnique Approach

Molecular interaction studies between nanoparticles (NPs) and biomolecules are of great importance in the field of nanomedicine as they affect many physiological processes. Therefore, the interaction of zinc sulphide nanoparticles (ZnS NPs) with calf thymus deoxyribonucleic acid (CT DNA) and its significance was analyzed using ultraviolet (UV)–visible light, fluorescence, circular dichroism (CD), zeta potential, viscometry, electrochemical, and polymerase chain reaction methods. Fluorescence quenching analysis revealed that the fluorescence of ZnS NPs was quenched using CT DNA through a static quenching mechanism. The negative values of thermodynamic parameters (∆G, ∆H, and ∆S) showed that the binding process was spontaneous, exothermic, and van der Waals or hydrogen bonding plays an important role in the interaction of ZnS NPs with CT DNA. Thermal melting (Tm) studies indicated a decrease in the Tm of CT DNA, suggesting the destabilization of CT DNA upon interaction with ZnS NPs. In addition, the results obtained from competitive binding, zeta potential, CD, and viscometry measurements showed that the interaction of ZnS NPs with CT DNA is through groove binding. Electrochemical analysis further confirmed the observed results from various spectroscopic and other related studies, in which decrease in the redox peak current along with changes in peak potential (CV) and increase in the electrical resistance (EIS) indicated the interaction between ZnS NPs and CT DNA. Furthermore, PCR analysis using DNA polymerase revealed the potential of ZnS NPs to inhibit DNA replication in vitro. ZnS NP–CT DNA interaction studies can be explored to define new horizons in biomedical applications of ZnS NPs

Nitrile Hydratase-Mediated Conversion of Acrylonitrile by Rhodococcus rhodochrous (RS-6)

BACKGROUND Acrylamide is an important monomer for the synthesis of polyacrylamide, which has wide applications in industries. This molecule can be produced by the hydration of acrylonitrile, catalyzed by the enzyme nitrile hydratase (NHase) secreted by microorganisms. Herein, synthesis of acrylamide was carried out by soil isolate Rhodococcus rhodochrous (RS-6) contains NHase. The critical parameters affecting the bioconversion process such as pH, temperature, substrate concentration, resting cell concentration and acrylamide concentration were optimized by changing one parameter at a time. RESULTS The optimum conditions for acrylonitrile conversion to acrylamide were observed at pH 7.0, temperature 15 °C, substrate concentration 1250 mmol L–1 and 1.4 mg dcw mL–1 concentration of resting cells. Under these improved conditions the entire bioconversion of acrylonitrile to acrylamide was observed within 75 min of incubation. The NHase of resting cells of R. rhodochrous (RS-6) showed tolerance to acrylonitrile (7% w/v) and acrylamide up to 30%. Laboratory-scale production by fed-batch method resulted in an accumulation of 574 g L-1 acrylamide in 9 h. CONCLUSION The NHase-containing resting cells of R. rhodochrous (RS-6) catalyzed the maximum conversion of acrylonitrile to acrylamide under optimized conditions. © 2020 Society of Chemical Industr
