Highly active and selective supported rhenium catalysts for aerobic oxidation of n-Hexane and n-Heptane [PDF]

open access: yes, 2018
A series of derivative C-scorpionate rhenium complexes, i.e., [ReCl2{NNC(O)C6H5} (Hpz)(PPh3)2] (A) (where Hpz is pyrazole), [ReCl2{NNC(O)C6H5}(Hpz)2(PPh3)] (B), [ReClF {NNC(O)C6H5}(Hpz)2(PPh3)] (C), and their precursor [ReOCl3(PPh3)2] (D), immobilized on

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near

Transition region ignition characteristics of n-heptane fuel sprays [PDF]

open access: yes
Ignition studies were perferred on monodisperse n-heptane sprays at atmospheric pressure over a range of equivalence ratios and droplet diameters. A capacitive discharge spark ignition system was used as the ignition source, providing independent control

Medium dependence of asphaltene agglomeration inhibitor efficiency

open access: yes, 2007
Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not ...

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

open access: yesEnergy Science &Engineering, EarlyView.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.
