Improving the efficiency and longevity of energy storage systems based on Li- Na-ion rechargeable batteries presents a major challenge. The main problems are essentially capacity loss limited cyclability. These effects due to hierarchy factors spanning various length time scales, interconnected in complex manner. As consequence, spite several decades research, proper understanding ageing proces...

The analysis of geological samples that have several chemically diffused zones which formed under certain physico-chemical condition is difficult to achieve. quantitative estimations the minerals in such are tedious. present work demonstrates application LIBS for qualitative and analyses a quartz-fluorite composite was procured from an amygdaloidal basalt Deccan Traps, India. presence weak emis...

Abstract There is currently substantial interest in commercializing perovskite solar cells as they offer superior properties over silicon-based cells, such ability for bandgap tuning, higher absorption coefficients, and potentially lower manufacturing costs. However, trap states originating from ionic vacancies, imperfect interfaces, grain boundaries have hampered their performance long-term st...

Breath analysis, a promising new field of medicine and medical instrumentation, potentially offers noninvasive, real-time, and point-of-care (POC) disease diagnostics and metabolic status monitoring. Numerous breath biomarkers have been detected and quantified so far by using the GC-MS technique. Recent advances in laser spectroscopic techniques and laser sources have driven breath analysis to ...

The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...

This paper describes a high-resolution, infrared spectroscopic survey of young, low-mass stars designed to identify and characterize pre−main-sequence spectroscopic binaries. This is the first large infrared radial velocity survey of very young stars to date. The frequency and mass ratio distribution of the closest, low-mass binaries bear directly on models of stellar, brown dwarf, and planetar...

Chemical grafting of Polyaniline (PAni) and chitosan (CS) as has been carried out with formaldehyde as grafting agent and ammonium persulfate as an initiator. For this reason aniline monomers were copolymerized with chitosan and were chemically polymerized. The synthesized copolymer was Characterized using Fourier transform infrared spectroscopy (FTIR), UV-Visible, scanning electron microscopy ...
