Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Low-Complexity Partial Transmit Sequence Methods Using Dominant Time-Domain Samples for Multicarrier Faster-Than-Nyquist Signaling

IEEE Access, 2019
In Multicarrier faster-than-Nyquist (MFTN) systems, one of the most important problems of MFTN signaling is high peak-to-average power ratio (PAPR). In this paper, partial transmit sequence (PTS) method is adopted to resolve this problem, and we focus on

Interblock-interference-free precoding using square-root decomposition for faster-than-Nyquist signaling

Digital Communications and Networks
Precodings using square-root decomposition, including Cholesky and G-To-Minus-Half (GTMH) precodings, are promising for eliminating the Faster-Than-Nyquist (FTN)-induced Intersymbol-Interference (ISI).

Serial and Parallel Concatenations Based on Faster Than Nyquist Signaling [PDF]

2006 IEEE International Symposium on Information Theory, 2006
We investigate the performance of concatenated coding schemes based on Faster Than Nyquist (FTN) signaling over the AWGN channel. We test both serial and parallel concatenations. In serial concatenation the FTN signaling is considered as the inner encoder and the outer code is a rate b/c convolutional code.

Coded Faster-than-Nyquist Signaling for Short Packet Communications

, 2021
© 2021 IEEE.Ultra-reliable low-latency communication (URLLC) requires short packets of data transmission. It is known that when the packet length becomes short, the achievable rate is subject to a penalty when compared to the channel capacity.

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially
