Efficient Electrocatalytic Conversion of CO2 to Pure Formic Acid Solutions via Strain‐Engineered Bismuth Nanosheets

open access: yesAdvanced Science, EarlyView.
Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

open access: yesAdvanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

open access: yesAdvanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Ferroelectric HfO2/ZrO2 Superlattice Capacitors With High Center to Edge Wafer‐Scale Uniformity

open access: yesAdvanced Electronic Materials, EarlyView.
“Enhanced wafer‐scale device uniformity on 150 mm wafers is demonstrated using ferroelectric superlattice HfO2/ZrO2 (HZO) capacitors, as compared to conventional solid solution HZO capacitors. Superlattice HZO exhibits improved ferroelectric memory properties, including a broader polarization window, greater endurance, reduced leakage, and superior ...

Atomic Layer Deposition of Disordered p‐Type SnO Using a Heteroleptic Tin(II) Precursor: Influence of Disorder on P‐Channel SnO Thin‐Film Transistor Characteristics

open access: yesAdvanced Electronic Materials, EarlyView.
Disordered p‐type SnO thin‐films are deposited via atomic layer deposition using a novel heteroleptic precursor. These films enable low‐temperature fabrication of thin‐film transistors with excellent stability and mobility. Their potential compatibility with flexible substrates and integration with n‐type IGZO transistors makes them candidates for ...

Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors

open access: yesAdvanced Electronic Materials, EarlyView.
MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...
