Weak ‘delayed’ luminescence is emitted after the reaction of active nitrogen with mixed host–guest aromatic polycrystals at 77 K. A spectroscopic investigation of this delayed luminescence shows that: (i) the spectrum of ...

In this work, we report a regioselective sulfonamidation of N-(2-hydroxyaryl)amides with iminoiodinanes and iodine in visible light at room temperature. The method does not require a strong oxidant, metal or photocatalyst ...

The methanol oxidation reaction has been studied in trifluoromethanesulphonic acid monohydrate solutions containing low concentrations of water. Cyclic voltammetry and potentiostatic polarisation curves clearly indicate ...

The kinetics of chemisorption have been inadequately represented in the literature by second-order equations and by Elovich equations. The conditions at which non-valid equations become apparently applicable are discussed. ...

Partial molar volumes of a number of α-aminocarboxylic acids in water at 25°C are measured. The results indicate that 4.33 ± 0.39 water molecules hydrate an α-amino acid. Contributions of the side chains or their constituent ...

A facile, high-yielding synthetic protocol has been developed to access azepino-fused porphyrins via iodine(III)-mediated oxidative intramolecular cyclization of β-imidazole or benzimidazole substituted porphyrins. The ...

This chapter synthesizes how nanoscale phenomena—quantum tunneling and confinement, large surface-to-volume ratios, ballistic transport, anisotropic carrier motion in low-symmetry 2D materials, and plasmonics—reshape device ...

This paper presents a large step-down buck converter topology employing a coupled inductor and a singles-witch configuration to achieve efficient step-down voltage conversion with an extended conversion ratio. The proposed ...

Extracting structured information from zeolite synthesis experimental procedures is critical for materials discovery, yet existing methods have not systematically evaluated Large Language Models (LLMs) for this domain-specific ...

Solvation dynamics play a central role in shaping nucleic acid structure, flexibility, and recognition, yet their molecular origins remain poorly understood for RNA, whose diverse architectures and intrinsic conformational ...
