Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices
Advanced Functional Materials, EarlyView.This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

ALKALI TREATMENT OF POLYESTER FIBERS
Sen'i Gakkaishi, 1960 Fibers, made from polyesters of β-hydroxyethoxy aromatic acids, and their copolyester, and those from polyethylen terephthalate (PET), were treated with aqueous caustic soda solutions.Rate constants of solution, k (g/hr/cm2), are calculated from the equationwhere x is the loss of weight by solution, d0 (cm) the initial diameter of a fiber, t (hr) the ...

Advanced Functional Materials, EarlyView.Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...

Effect of Ethanol on Alkali and Acrylonitrile Treatments for Cotton [PDF]
Polymer Journal, 1978 Cotton fibers were pretreated with 5.4-N sodium hydroxide in an ethanol—water (volume ratio, 30: 70) mixture and then cyanoethylated with acrylonitrile. The crystalline structure of the cyanoethylated cotton fibers was investigated by the X-ray method and compared with that of the cotton fibers, pretreated with 5.4-N aqueous sodium hydroxide and ...
