Gas Separation Silica Membranes Prepared by Chemical Vapor Deposition of Methyl-Substituted Silanes

Membranes, 2019
The effect on the gas permeance properties and structural morphology of the presence of methyl functional groups in a silica membrane was studied. Membranes were synthesized via chemical vapor deposition (CVD) at 650 °C and atmospheric pressure ...

Kinetic Study of CVD Reaction by Area-Controlled CVD.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2000
A new method for analyzing the kinetics of CVD reactions is proposed using area-controlled CVD. Catalyst particles were set at the dead end of a narrow straight tube. Water vapor generated at the catalyst from H2 and CO2 was fed into the reaction zone to react with TiCl4, which diffused from the opposite side. Then, TiO2 was formed and deposited on the

MOCVD‐Grown MoS2 Wafers as a Transfer‐Free Platform for Top‐Gate Devices via Dry Interface Engineering

Advanced Materials, EarlyView.
We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

Advanced Materials, EarlyView.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

Advanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...
