Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Enhanced Long-term Stability and Carbon Resistance of Ni/MnxOy-Al2O3 Catalyst in Near-equilibrium CO2 Reforming of Methane for Syngas Production

Bulletin of Chemical Reaction Engineering & Catalysis, 2020
Herein we study the catalytic activity/stability of a new generation of cheap and readily available Ni and Al-based catalysts using two Mn precursors, namely Mn(NO3)2 and Mn(EDTA)2- complex in the reaction of CO2 reforming of methane. In this respect, Ni/

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Effect of Al2O3 on the Ni-Al2O3/SiO2 catalysts for the production of syngas from reforming of CH4 with CO2 and O2(甲烷二氧化碳氧化重整制合成气反应中Al2O3对Ni-Al2O3/SiO2催化剂性能的影响)

Zhejiang Daxue xuebao. Lixue ban, 2008
在流化床中评价了用于甲烷二氧化碳氧化重整制合成气反应的Ni-Al2O3/SiO2催化剂体系（NixAlSi，x代表Al的质量分数，Ni的质量分数为4%）的催化性能.利用XRD，CO2(O2)-TPD，积炭量测定等手段对催化剂进行了表征.结果表明，Al2O3的添加促进了Ni金属的分散；增强了对CO2和O2的吸附能力，使催化剂的抗积炭性能得到很大的提高，延缓了催化剂的失活.
