Advanced Science, EarlyView.This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Glycerol as Precursor of Organoselanyl and Organotellanyl Alkynes
Molecules, 2017 Herein we describe the synthesis of organoselanyl and organotellanyl alkynes by the addition of lithium alkynylchalcogenolate (Se and Te) to tosyl solketal, easily obtained from glycerol.

Advanced Science, EarlyView.A dilute hybrid electrolyte containing only 10 mol% [EMIM][DEP] simultaneously reorganizes the water hydrogen‐bond network and creates an ionic‐liquid‐rich region at the anode. This coupled bulk and interfacial regulation suppresses freezing and hydrogen evolution, broadens the electrochemical stability window, and enables an aqueous LMO/LTP full cell ...

Recent advances in carbocupration of α-heterosubstituted alkynes
Beilstein Journal of Organic Chemistry, 2010 Carbocupration of α-heterosubstituted alkynes leads to the formation of stereodefined functionalized vinyl copper species as single isomer. Recent advances in the field show that a simple pre-association of the organometallic derivative with an ...

Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions
Advanced Science, EarlyView.This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.
