Base-catalyzed Polymerization of Cyclic Dimethylpolysiloxanes

The Journal of the Society of Chemical Industry, Japan, 1963
環状ジメチルポリシロキサンの開環重合触媒として, 水酸化セシウム, カセイカリなどの強塩基性アルカリ金属水酸化物を使用した場合は, 触媒を完全に取り除くかまたは不活性化しないと高温度で重合体が解重合をひき起す。著者らは, 強塩基性を示すが高温度では不活性な物質に分解する水酸化テトラアルキルアルソニウム化合物[(n-C4H9)4・AsOH],水酸化テトラアルキルスチボニウム化合物[(n-C4H9)4SbOH],[(CH3)4SbOH] , 水酸化トリアルキルスルホニウム化合物[(CH3)3SOH],[(C2H5)3SOH]グアニジン[HN=C(NH2)2],およびアミジン〓などについて環状ジメチルポリシロキサンの開環重合を検討して,[(n-C4H9)4AsOH ...

Bioactivity‐Guided Isolation of β‐Sitosterol From Terminalia glabrescens as a Potent Anti‐Zika Virus Agent

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT Zika virus (ZIKV) infection remains a global health concern due to its neurological complications and the lack of specific drugs or vaccines. This study investigated the anti‐ZIKV potential of an ethanolic extract from Terminalia glabrescens leaves.

Leaf Litter Decomposition Along an Elevation Gradient Across Two Contrasting Forest Types: Implications for Future Climate Change

Ecological Research, Volume 41, Issue 1, January 2026.
We investigated how leaf litter decomposition rates of two dominant tree species—Fagus crenata at lower elevations and Abies mariesii at higher elevations—vary along an elevational gradient in a mountain range. Within each species' range, decomposition proceeded faster at lower, warmer elevations, with A.

Multitarget Anti‐Obesity Potential of Baccaurea motleyana Fruit: Insights From Biochemical, Histological, and In Silico Analyses

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Obesity, associated with insulin resistance, dyslipidemia, hepatic steatosis, and inflammation, remains a global challenge. This research evaluated the anti‐obesity and hepatoprotective potential of the Baccaurea motleyana fruit ethanol extract (BMF‐EE) in high‐fat‐diet (HFD)‐induced obese rats. Phytochemicals in BMF‐EE were profiled by GC–MS.

Supercritical Fluid Chromatographic Separation of Dimethylpolysiloxane Polymer [PDF]

Bulletin of the Korean Chemical Society, 2005
The use of compressed (dense) gases and supercritical fluids as chromatographic mobile phases in conjunction with liquid chromatographic (LC)-type packed columns was first reported by Klesper et al. in 1962. During its relatively short history, supercritical fluid chromatography (SFC) has become an attractive alternative to GC and LC in certain ...
