Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

Advanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Arrayed Magnetic Accelerator Synergistically Enhances Orthodontic Tooth Movement via Microtubule Assembly‐Mediated Periodontal Remodeling

Advanced Science, EarlyView.
Mechanical orthodontic treatment for malocclusion is limited by slow remodeling and risks due to poor biomechanical sensing. This study shows that static magnetic fields (SMFs) enhance mechanical sensation in periodontal ligament cells, promoting inflammation and osteoclast activity.

Ion‐Exchange‐Driven Ternary Organic Neuromorphic Devices with High Efficiency and Stability

Advanced Science, EarlyView.
Spontaneous ion exchange in a ternary polymer–ionic liquid blend disrupts the phase‐separated ionic domains of the binary film and creates a more homogeneous polymer–ion environment. This ionically reorganized matrix enables stable and efficient electrochemical doping, leading to ion‐gel‐gated organic electrochemical transistors with enhanced ...

Glucose and Glutamine Deprivation Promotes Breast Cancer Lung Metastasis via BRD4‐Dependent Enhancer Activation

Advanced Science, EarlyView.
To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

Kernel Affine Projection for Nonlinearity Tolerant Optical Short Reach Systems

, 2019
Nonlinearity is one of the key issues that hinder the development of high-capacity optical short reach systems. This paper proposes three variants of kernel affine projection (KAP) algorithms, all of which combine kernel mapping and affine projection in ...
