Sustainability Disclosure and Firm Value: External ESG Evaluation and the Role of Advertising Intensity

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines whether sustainability reporting becomes relevant to firm value partly through externally evaluated ESG performance and whether this process varies with firms' communication environments. Using firm‐year data on Korean listed firms from 2019 to 2021, we estimate regression models with year and industry fixed effects and ...

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

open access: yesDroplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Engineering Zn Powder Anodes for Advanced Aqueous Zn‐Based Batteries

open access: yesEcoEnergy, EarlyView.
Zn powder (ZnP) anodes have attracted growing interest in aqueous Zn‐based batteries (AZBs) because they enable high Zn utilization, relaxed mechanical constraints, and versatile electrode fabrication. This review systematically summarizes recent advances in ZnP anodes, focusing on crystallographic engineering, interfacial regulation, electrode ...

Silanizing Glassware

Current Protocols in Molecular Biology, 1994
AbstractThis unit presents a procedure to silanize (siliconize) glassware to prevent adsorption of solute to the glass surface or to increase its hydrophobicity. This is particularly important when dealing with low concentrations of particularly “sticky” solutes such as single‐stranded nucleic acids or proteins.

Thermal decomposition of silane

Journal of the American Chemical Society, 1986
The essential features of the potential energy surface for the thermal decomposition of silane have been calculated with extended basis sets, augmented by correlation corrections. It is predicted that the transition state for the molecular elimination lies 56.9 kcal/mol above silane.

To silanate or not to silanate: making a clinical decision.

Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995), 2001
Etched porcelain-bonded restorations have become the treatment of choice for the esthetic restoration of anterior teeth. The bond strength of composite resin to properly etched and silanated porcelain exceeds the cohesive strength of porcelain. Although bonding to enamel is accomplished by only etching the surface to create micromechanical retention ...

Neutral higher silane molecules in silane plasmas

Applied Physics Letters, 1998
Neutral higher silane molecules in silane radio frequency glow discharge plasmas are investigated using photoionization mass spectroscopy at various radio frequency (rf) powers and total pressures. Densities of higher silane molecules increase with rf power up to 10 W, and then decrease at 10–100 W.
