Article Abstract
Liquid crystal biosensors serve an essential role to detect biomolecules and chemical events as an effective, simple and early detection tool. The detection of Human serum albumin protein by a room temperature liquid crystal 4́-pentyl-4-biphenylcarbonitrile has been investigated using multiple techniques such as Polarizing optical microscope, Raman spectroscopy and molecular docking. The dynamics of director transfigurations of the liquid crystal molecule in the presence of protein through interactions are reported in the study. The change in the alignment of liquid crystal molecules during the nematic phase is observed under a polarizing optical microscope. The interactions through which the liquid crystal molecules bind with protein is depicted from the docking analysis. The residues in the active sites confirm their presence from docking studies. The spectral behaviour has been investigated by temperature-dependent Raman spectroscopy. The findings from Raman spectra for the interaction between these compounds correlates with the residues confirmed from molecular docking analysis.

The supported catalytically active liquid metal solution (SCALMS) concept is based on catalytically active metals dissolved in a low-melting-point liquid metal matrix. These solid alloy particles, deposited over a high area support, transform into a liquid alloy under reaction conditions. In this work, GaPt SCALMS materials of varying composition are investigated and focus on the change in the alloy composition during preheating, the actual high temperature propane dehydrogenation at 823 K, and after cool-down.

This study comprehensively analyses two new ruthenium(III) complexes, [RuCl(Nic)][(CH)NH]DMF, 1, and [RuCl(3-HPA)][3-HHPA](EtOH), 2, (where Nic = nicotinic acid (vitamin B3), 3-HPA = anion of a 3-hydroxypicolinic acid), as potential antimicrobial agents, highlighting their physicochemical properties, nanoparticle formation, and cytotoxic activity. The complexes were fully characterised by a single crystal X-ray diffraction technique, Fourier-transform infrared, energy-dispersive X-ray, and electron paramagnetic resonance spectroscopies. The synthesis of micro- and nanoparticles (NPs) of these complexes was performed using the liquid anti-solvent crystallisation method.

In recent years, amino acids have garnered extensive attention as environmentally friendly, small-dose additives for modulating hydrate formation and aggregation behavior. Amino acids, due to their amphiphilic nature, can adsorb at the gas-liquid interface and on hydrate crystal surfaces, thereby modifying interfacial properties and influencing crystal growth patterns. In our measurements, the amino acids displayed a concentration-dependent "double effect".

The synthesis of thin crystalline two-dimensional polymers (2DPs) typically relies on reversible dynamic covalent reactions. While substantial progress has been made in solution-based and interfacial syntheses, achieving 2DPs through irreversible carbon-carbon coupling reactions remains a formidable challenge. Herein, we present an on-liquid surface (a mixture of N,N-dimethylacetamide and water, DMAc-HO) synthesis method for constructing diyne-linked 2DP (DY2DP) crystals via Glaser coupling, assisted by a perfluoro-surfactant (PFS) monolayer.

Solid-state electrolytes (SSEs) are being extensively researched as replacements for liquid electrolytes in future batteries. Despite significant advancements, there are still challenges in using SSEs, particularly in extreme conditions. This study presents a hydrated metal-organic ionic cocrystal (HMIC) solid-state ion conductor with a solvent-assisted ion transport mechanism suitable for extreme operating conditions.
