Membrane Assemblies with Soft Protective Layers: Dense and Gel‐Type Polybenzimidazole Membranes and Their Use in Vanadium Redox Flow Batteries

Small, Volume 18, Issue 50, December 15, 2022., 2022
Polybenzimidazole (PBI) membranes efficiently hinder the crossover of vanadium ions, but have high resistance. Thin PBI membranes (e.g., <4 µm) have adequate resistance but need to be supported. Here, thin PBI is protected by assembling it between two 60 µm thick soft sulfuric acid swollen PBI gel layers, which are highly conductive (>500 mS cm−1) and ...

Emerging Proximal Liquid Biopsy Approaches for Detecting Residual Disease and Predicting Recurrence in Head and Neck Cancer: A Review and Proposal of Novel Liquid Staging

Head &Neck, EarlyView.
ABSTRACT Background Head and neck squamous cell carcinoma remains challenging due to high recurrence rates and poor survival outcomes. Developing precise technologies for disease burden assessment, treatment response, and minimal residual disease (MRD) surveillance is crucial for improving prognosis. Methods This review explores the potential of liquid

Phonon Engineering of Micro‐ and Nanophononic Crystals and Acoustic Metamaterials: A Review

Small Science, Volume 3, Issue 1, January 2023., 2023
Phononic crystals and acoustic metamaterials with phonon wave manipulation capabilities have attracted considerable attention. This review summarizes the progress and identifies gaps in phonon engineering at the micro‐ and nanoscales using phononic crystals and metamaterials due to their potential significance in modern electronic applications.

Diagrammatic Schemes for Nonlinear Optical Interactions

Journal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (

Exploring Time‐Domain Femtosecond Rotational Coherent Raman Scattering for Diagnostics

Journal of Raman Spectroscopy, EarlyView.
The diagnostic potential of femtosecond (fs) rotational coherent Raman scattering (RCRS) in the time domain is initially investigated. Experiments in air and pure nitrogen are reported, revealing the temperature sensitivity in the recorded fs‐RCRS temporal scans.

Why Hoffmann? His Chemistry**

The Chemical Record, Volume 22, Issue 12, December 2022., 2022
Roald Hoffmann was the perfect theoretical chemist to collaborate with R. B. Woodward on the Principle of Conservation of Orbital Symmetry. This essay presents Hoffmann's capabilities as of May 5, 1964. Abstract Abstract: Why was it that Roald Hoffmann was the perfect collaborator for R. B.

Fast‐switchable polarization‐dependent bifocal lenses for AR displays

Journal of the Society for Information Display, EarlyView.
Polarization‐dependent bifocal Pancharatnam‐Berry phase lenses, fabricated via photoalignment, integrate bifocal functionality for AR displays. An electrically suppressed helix ferroelectric liquid crystal polarization rotator enables rapid switching (35 μs) between dual depths or field‐of‐views (FOVs) in longitudinal and transverse configurations ...

Design of a high‐performance advanced phase locked loop with high stability external loop filter

IET Circuits, Devices &Systems, Volume 17, Issue 1, Page 1-12, January 2023., 2023
Abstract For this task, an improved phase locked loop (PLL) was developed using a more sophisticated phase‐frequency detector with multiband flexible dividers that provide enhanced frequency resolution, a better spectrum, and a better output signal. Great timing jitter was the problem for the old PLL designs because of the unbalanced frequency transfer

BDLUT: Blind image denoising with hardware‐optimized look‐up tables

Journal of the Society for Information Display, EarlyView.
BDLUT(‐D) is a novel blind denoising method combining optimized lookup tables (LUTs) with hardware‐centric design. While BDLUT describes the LUT‐based network architecture, BDLUT‐D represents BDLUT trained with a specialized noise degradation model. Designed for edge deployment, BDLUT(‐D) eliminates neural processing units (NPUs) and functions as a ...

Explainable human‐in‐the‐loop healthcare image information quality assessment and selection

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Smart healthcare applications cannot be separated from healthcare data analysis and the interactive interpretability between data and model. A human‐in‐the‐loop active learning approach is introduced to reduce the cost of healthcare data labelling by evaluating the information quality of unlabelled medical data and then screening the high ...
