Context: There has been growing interest in amino acid ionic liquids because of their low-cost synthesis and superior biodegradability and biocompatibility compared to traditional ionic liquids. In this study, we have investigated the structure and dynamics of three ionic liquids consisting of N-butyl N-methyl piperidinium [Pip] cation with amino acid (lysine [Lys], histidine [His], and arginine [Arg]) anions. The radial distribution functions, the spatial distribution functions, and the coordination numbers have been used to analyze the structure in the bulk phase.

The substantial build-up of non-biodegradable plastic waste from packaging sector not only poses severe environmental threats but also hastens the depletion of natural petroleum-based resources. Presently, poly (3-hydroxybutyrate-co-3-hydroxy valerate) (PHBV), received enormous attention as ideal alternatives for such traditional petroleum-derived plastics based on their biocompatibility and superior mechanical properties. However, high cost of such copolymer, due to expensive nature of feedstock, inefficient microbial processes and unfavorable downstream processing strategies restricts its large-scale commercial feasibility in the packaging sector.

The hexatic phase is an intermediate stage in the melting process of a 2D crystal due to topological defects. Recently, this exotic phase was experimentally identified in the vortex lattice of 2D weakly disordered superconducting MoGe by scanning tunneling microscopic measurements. Here, we study this vortex state by the Nernst effect, which is an effective and sensitive tool to detect vortex motion, especially in the superconducting fluctuation regime.

The increasing demand for biopolymers across diverse fields, such as food, medicine, cosmetics, and environmental applications, has prompted researchers to explore novel molecules with enhanced functionalities that meet these demands. In this study, a thermophilic strain of Bacillus licheniformis was employed to produce a unique polyamino acid. This thermophilic isolate exhibited rapid growth at 50 °C in a sucrose mineral salts medium, resulting in a biopolymer concentration of 7.

In modern biological research, genetic transformation is an important molecular biology technique with extensive applications. In this work, we describe a new method for the delivery of plasmid DNA (pDNA) into a yeast species, . This method is based on the use of novel arginine-glucose-PEG functionalized hydroxyapatite nanoparticles (M-HAp NPs) as a vehicle which delivers pDNA into with a high transformation efficiency of 10 cfu μg of pDNA, without the need for preparation of competent cells.

Here, we report a simple '' co-precipitation reduction synthesis method for the preparation of nanocatalysts composed of Ag, Ni nanoparticles, and reduced graphene oxide (RGO). First-principles calculations based on Density Functional Theory (DFT) were performed to obtain the electronic structures and properties of Ag-Ni-graphene superlattice and to understand the interfacial interactions which exist at the interface between Ag, Ni, and graphene. The catalytic performance of the synthesized catalysts (Ag Ni) RGO were evaluated for four reactions (i) reduction of 4-nitrophenol (4-NP) in the presence of excess NaBH in aqueous medium, (ii) A3 coupling reaction for the synthesis of propargylamines, (iii) epoxidation of styrene, and (iv) 'Click reaction' for the synthesis of 1,2,3-triazole derivatives.

Here, we report an '' co-precipitation reduction based synthetic methodology to prepare CuFeO nanoparticle-reduced graphene oxide (CuFeO-RGO) nanocomposites. First principles calculations based on Density Functional Theory (DFT) were performed to obtain the electronic structures and properties of CuFeO, graphene and CuFeO-graphene composites, and to understand the interfacial interaction between CuFeO and graphene in the composite. The synergistic effect, which resulted from the combination of the unique properties of RGO and CuFeO nanoparticles, was exploited to design a magnetically separable catalyst and high performance supercapacitor.

Mechanical resonators are ubiquitous in modern information technology. With the possibility of coupling them to electromagnetic and plasmonic modes, they hold promise as the key building blocks in future quantum information technology. Graphene-based resonators are of interest for technological applications due to their high resonant frequencies, multiple mechanical modes and low mass.
