AI Article Synopsis
- Furfural can be oxidized to different compounds using hydrogen peroxide or photo-oxygenation, leading to 2[5H]-furanone or 5-hydroxy-2[5H]-furanone, respectively.
- The introduction of an amine function involves a photochemical process using tertiary amines derived from fatty aldehydes and cyclic secondary amines, some of which have hydrophobic n-alkyl side chains.
- The resulting compounds are amphoteric surfactants that feature both ammonium and carboxylate functions, with properties such as pK(N), isoelectric point, critical micelle concentration, and adsorption efficiency being evaluated.
Article Abstract
Furfural is oxidized to 2[5H]-furanone by using hydrogen peroxide or to 5-hydroxy-2[5H]-furanone by using photo-oxygenation. An amine function is introduced by photochemically induced radical addition of tertiairy amines, some of which carry an n-alkyl side chain as hydrophobic moiety. These amines are produced from fatty aldehydes and cyclic secondary amines. The resulting adducts are transformed into amphoteric surfactants possessing an ammonium and a carboxylate function. Amphoteric (pK(N) and isoelectric point) and surfactant properties such as the critical micelle concentration and the adsorption efficiency are determined.

The gene GAD1 encodes a glutamate decarboxylase, which is a rate-limiting enzyme for the biosynthesis of endogenous γ-aminobutyrate acid (GABA), but a potential role of GAD1 in regulating cadmium (Cd) tolerance needs to be further elucidated in plants. The objective of this study was to investigate Cd tolerance of creeping bentgrass (Agrostis stolonifera) and transgenic yeast (Saccharomyces cerevisiae) or Arabidopsis thaliana overexpressing AsGAD1. The Cd-tolerant creeping bentgrass cultivar LOFTSL-93 accumulated more endogenous GABA in relation to a significant upregulation of AsGAD1 in leaf and root than the Cd-sensitive W66569 in response to Cd stress.

Glutathione reductase (GR) maintains the cellular redox state by reducing oxidized glutathione to glutathione (GSH), which regulates antioxidant defense. Additionally, GR plays an essential role in photosynthesis; however, the mechanism by which GR regulates photosystem II (PSII) is largely unknown. We identified six, three, and three GR genes in Gossypium hirsutum, Gossypium arboreum, and Gossypium raimondii, respectively.

As a vital process for solar fuel synthesis, water oxidation remains a challenging reaction to perform using durable and cost-effective systems. Despite decades of intense research, our understanding of the detailed processes involved is still limited, particularly under photochemical conditions. Recent research has shown that the overall kinetics of water oxidation by a molecular dyad depends on the coordination between photocharge generation and the subsequent chemical steps.

Blue phase liquid crystal (BPLC) lasers exhibit exceptional optical quality and tunability to external stimuli, holding significant promise for innovative developments in the field of flexible optoelectronics. However, there remain challenges for BPLC elastomer (BPLCE) lasers in maintaining good optical stability during stretching and varying temperature conditions. In this work, a stretchable laser is developed based on a well-designed BPLCE with a combination of partially and fully crosslinked networks, which can output a single-peak laser under small deformation (44.

Salt stress is a vital environmental stress that severely limits plant growth and productivity. Prohexadione-calcium (Pro-Ca) has been extensively studied to regulate plant growth, development, and stress responses. However, the constructive role of Pro-Ca in alleviating damages and enhancing rice tillers' morph-physiological characteristics under salt stress remains largely unknown.
