From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

Advanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

Integration of Perovskite/Low‐Dimensional Material Heterostructures for Optoelectronics and Artificial Visual Systems

Advanced Functional Materials, EarlyView.
Heterojunctions combining halide perovskites with low‐dimensional materials enhance optoelectronic devices by enabling precise charge control and improving efficiency, stability, and speed. These synergies advance flexible electronics, wearable sensors, and neuromorphic computing, mimicking biological vision for real‐time image analysis and intelligent

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

Advanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

Advanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Jerk as an indicator of physical exertion and fatigue

Automation in Construction, 2019
Abstract Physical exertion may result in fatigue which is a key factor leading to increased risk of injury, reduced productivity, and decline in work quality in construction. Most practical fatigue assessments rely on subjective measurement scales including surveys and questionnaires.

A Case of a Man with Syncope After Physical Exertion

AJN, American Journal of Nursing, 2022
Editor's note: This is the next installment in a series on electrocardiogram (ECG) interpretation. Nurses in all settings should know the basics, as medications and physiological changes can cause cardiac arrhythmias. Each article will start with a brief case scenario and an ECG strip and then take you step by step through analyzing the heart rhythm.
