Truncated Conjugate Structure Improves Solar‐Driven Hydrogen Peroxide Production Catalyzed by Benzobisthiazole‐Based Conjugated Polymers

Advanced Science, Volume 13, Issue 7, 3 February 2026.
In this work, a novel molecular design strategy was employed to truncate large‐scale conjugated structures in covalent polymer materials. This approach significantly enhances the catalyst’s light‐harvesting capability, prolongs the lifetime of photogenerated charge carriers, and improves catalytic activity, thereby offering a new conceptual pathway for

Molecular Cages Based Materials for CO2 Capture, Separation, and Conversion

EcoMat, Volume 8, Issue 2, February 2026.
Molecular cages (MCs), boasting soluble, regenerable traits and precisely tunable structures, exhibit substantial potential for efficient CO2 capture, separation, and conversion. This review thoroughly explores MCs' recent advancements, analyzes current unresolved challenges, and provides forward‐looking perspectives to tackle pressing carbon‐related ...

Optimized T1‐weighted MP‐RAGE MRI of the brain at 0.55 T using variable flip angle coherent gradient echo imaging and deep learning reconstruction

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1169-1176, February 2026.
Abstract Purpose To propose and evaluate an optimized MP‐RAGE protocol for rapid T1‐weighted imaging of the brain at 0.55 T. Methods Incoherent and coherent steady state free precession (SSFP) RAGE kernels with constant and variable excitation angles were investigated in terms of the white matter SNR and the white matter–gray matter signal difference ...

5G new radio multiuser precoding in geostationary satellite networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 60-72, January/February 2026.
This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...

Estimation of Synchrophasors in Intelligent Electrical Networks: from Models to Design Restrictions

Revista Elektrón, 2017
We first present a detailed review of two popular classes of model based synchrophasor estimators. They are the discrete Fourier transform (DFT) and the Taylor-Fourier transform (TFT) class estimators, which arise from constant or polynomial phasor ...
