The Determination of Methimazole by Infrared Spectrophotometry
Journal of AOAC INTERNATIONAL, 1965 Abstract A method for the determination of methimazole by column chromatography and infrared spectrophotometry was subjected to collaborative study in four district laboratories. Although the results were favorable, they were not sufficiently precise nor accurate to recommend the method for adoption.

Smart Molecules, EarlyView.This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.

Integrative Zoology, EarlyView.This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Integrative Zoology, EarlyView.We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

SYNTHESIS OF ETHYL FATTY ALKYL ETHERS FROM COCONUT (Cocos nucifera L.) FATTY ALCOHOLS
Annals of Tropical Research, 1987 Ethyl fatty alkyl ethers were synthesized using coconut fatty alcohols as the starting raw materials. The fatty alcohols were converted into their corresponding bromides which were then made to react with ethanolic potassium hydroxide.

Photochemistry and Photobiology, EarlyView.This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.
