Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Closed-Form Least-Squares Design of Fast-Convolution Based Variable-Bandwidth FIR Filters

open access: yesIEEE Open Journal of Signal Processing
This paper introduces a closed-form least-squares (LS) design approach for fast-convolution (FC) based variable-bandwidth (VBW) finite-impulse-response (FIR) filters.

Successful aging as an oxymoron

open access: yesInternational Journal of Ageing and Later Life, 2009
Notions of what it means to age well or successfully are central to social gerontological research and practice. As such, one would expect that there would be consensus as to what the construct of successful aging means and/or how aging well is achieved.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Hu Ping

open access: yes, 2021
From 1931 to 1937, Hu Ping was a well-known left-wing film star and film critic (“Progressive Star”). Her abrupt withdrawal from the film industry in 1937, after the Chinese-Japanese War in Shanghai (also known as the “8.13 Incident”), led to repeated mentions in the wartime and post-war press about her, most of which portrayed her as a “fallen ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.
