Composés d'addition des halogénures de niobium(V) et de tantale(V): II. Stabilité relative des composés des chlorures avec quelques éthers, sulfures et nitriles

CHIMIA, 1971
New NMR methods for the determination of relative stability constants are developed. These methods are used for the study of niobium(V) and tantalum(V) chlorides adducts with series of ethers, sulfides, and nitriles. The relative stabilities of nitriles

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

Advanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

Morphology–acidity synergy in ZSM-5 for selective para-xylene synthesis via CO2/H2-mediated toluene methylation

Journal of CO2 Utilization
CO2/H2-mediated toluene methylation over metal oxide–zeolite bifunctional catalyst offers a sustainable route for para-xylene (PX) synthesis, yet how zeolite morphology and acidity synergistically govern this coupled process remains unclear.

CH2 Linkage Effects on the Reactivity of Bis(aminophosphine)–Ruthenium Complexes for Selective Hydrogenation of Esters into Alcohols

Scientific Reports, 2017
A novel ruthenium complex binding to two subtly different aminophosphine ligands, (o-PPh2C6H4CH2NH2)(o-PPh2C6H4NH2)RuCl2, was successfully isolated. This bis(aminophosphine)–ruthenium complex shows efficient activity in both dimethyl oxalate (DMO) and ...

Thermal transitions and structural properties of synthetic cholesterol alkyl and alkenyl ethers: analogues of biological cholesterol esters.

Journal of Lipid Research, 1983
Nine even-numbered saturated (C4 to C20) and two unsaturated (C18:1, C18:2) cholesterol alkyl ethers were studied by differential scanning calorimetry, polarizing microscopy, and X-ray powder diffraction.

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

Advanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐

POLYBROMINATED DIPHENYL ETHERS (PBDEs) AND POLYCHLORINATED BIPHENYLS (PCBs) IN HOUSEHOLD DUST IN BIRMINGHAM, UK. [PDF]

Polychlorinated biphenyls (PCBs) are persistent organic pollutants that were used primarily as insulating fluids in electrical equipment and were banned in the 1970s, even so they are still being found in humans.

PREPARATION OF THE ETHERS OF VINYL ALCOHOL

, 1932
The simple vinyl alkyl ethers are readily prepared from the β-bromo-ethyl ethers by the action of solid sodium hydroxide. Besides the vinyl ethers, the dialkyl ethers of diethylene glycol are formed in these reactions. β-Bromo-ethers are obtainable from
