Summary: This study reports on a combined thermal analysis, variable temperature diffraction analysis, and X-ray charge density analysis of 2:2 nicotinic acid: gallic acid (NAGA) co-crystal, which provides insights into the dynamics of co-crystal growth. The transformation of precursor gallic acid monohydrate to gallic acid anhydrate upon heating leads to the disintegration of the co-crystal assembly. Electrostatic and topological analysis of intermolecular interactions in the co-crystal assembly were performed using experimental charge density analysis and compared with theoretical structure factors obtained from DFT calculations, resulting in excellent agreement. The co-crystallization begins with the formation of an NAMIDLINE HORIZONTAL ELLIPSISNA zwitterion backbone, followed by the binding of the hydrated gallic acid coformer via electrostatic interactions. This study highlights the importance of thermal analysis and in situ diffraction analysis combined with multipolar refinement in understanding co-crystal growth.

Summary: This study comprehensively summarized and synthesized the existing evidence for lesser known uses of gabapentin and pregabalin in otolaryngology. The most promising potential uses identified were for improving swallowing, trismus, and narcotic overuse after radiation therapy. Additionally, GABA analogues showed potential in improving nonorganic voice disorders, but the benefit for globus pharyngeus related to laryngeal sensory neuropathy remains inconclusive.

Summary: The functional properties of mulberry leaves were improved by enriching them with gamma-aminobutyric acid (GABA). The application of sodium glutamate immersion, cold shock, and anoxic treatment significantly increased the GABA content and the quantity of active phenolics. The particle size of the GABA-enriched mulberry leaf powders affected their physical properties, release of active compounds, and antioxidant and inhibition abilities. The addition of powders effectively delayed the staling of bread without altering its taste.

Summary: In this study, we investigated the role of GABA in crops and found that exogenous application or endogenous regulation of GABA by gene-editing technology can promote pesticide detoxification and enhance crop tolerance. This is achieved by regulating the GABA shunt pathway and polyamine pathway in plants. Additionally, we unexpectedly discovered that GABA promotes stomatal closure, reducing pesticide absorption.

Summary: Inhibition of PD-1 and its ligands PD-L1 and PD-L2 by monoclonal antibodies pembrolizumab and nivolumab has shown breakthrough therapies in a wide range of cancers. However, little is known about their vibrational features. This study employed quantum chemistry calculations to explore the binding modes and vibrational properties of these antibody drugs using Raman scattering spectroscopy. The results provide insights into their harmonic vibrational wavenumbers, particularly in the range of 2,750 to 3,750 (1,200 to 1,750) cm(-1).

Summary: This study presents the growth of monoclinic gamma-aminobutyric acid (GABA) crystals from an aqueous ethanol solution. The crystal structure was confirmed to be monoclinic with space group P21/c using X-ray diffraction analysis. Thermal stability and melting point of the GABA crystal were investigated.

Summary: In this study, L-histidinium hydrogen oxalate crystal was successfully synthesized using the slow solvent evaporation method, and its vibrational behavior under different pressures was investigated by Raman spectroscopy. A conformational phase transition was observed from the analysis of the band behavior within the pressure range of 1.5-2.8 GPa, characterized by the disappearance of lattice modes. A second phase transition, now of structural type, close to 5.1 GPa was also observed.

Summary: Carbon nanotubes (CNTs) are important nanomaterials with various applications, but their increased production and use raise concerns about their potential impacts on the environment. In this study, we assessed the cytogenotoxic potential of carboxylated multi-walled carbon nanotubes (MWCNT-COOH) and their influence on the methylation patterns of Lactuca sativa meristematic cells. Our results showed that MWCNT-COOH induced root elongation at lower concentrations and decreased seed germination at higher concentrations. Cytogenetic analysis revealed increased chromosomal aberrations and micronucleus frequency, suggesting genotoxic effects. Additionally, MWCNT-COOH altered cytosine methylation profiles, with hypermethylation at lower concentrations and hypomethylation at higher concentrations.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
