Flexible lithium‐ion batteries: Materials design, interfacial regulation, and strain‐adaptive device architectures

FlexMat, EarlyView.
This review highlights recent advances in flexible lithium‐ion batteries for wearable and deformable electronics. It systematically examines deformable electrodes, mechanically compliant gel and solid‐state electrolytes, and strain‐adaptive cell architectures, alongside an analysis of mechano‐electrochemical coupling under dynamic deformation.

Effects of ice-wedge degradation and warming on Arctic tundra vegetation across a climatic gradient using a nitrogen-based model

Arctic, Antarctic, and Alpine Research
Ice-wedge polygons in Arctic tundra landscapes influence hydrology, nutrients, thermal regimes, and vegetation. Ice-wedges are particularly vulnerable to warming events, and widespread degradation has been observed in recent decades.

Vegetation composition and shrub extent on the Yukon coast, Canada, are strongly linked to ice-wedge polygon degradation

Polar Research, 2016
Changing environmental and geomorphological conditions are resulting in vegetation change in ice-wedge polygons in Arctic tundra. However, we do not yet know how microscale vegetation patterns relate to individual environmental and geomorphological ...

BIG IMAGERY AND HIGH PERFORMANCE COMPUTING AS RESOURCES TO UNDERSTAND CHANGING ARCTIC POLYGONAL TUNDRA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Permafrost thaw has been observed at several locations across the Arctic tundra in recent decades; however, the pan-Arctic extent and spatiotemporal dynamics of thaw remains poorly explained.

Cardiac Histomorphometric Implications Resulting From Chronic Nandrolone Decanoate Treatment in Rats Subjected to Resistance Training

Journal of Applied Toxicology, EarlyView.
ABSTRACT The effects of anabolic steroid abuse on the cardiac tissue of resistance training practitioners are poorly understood. Herein, we present the histomorphometric implications of resistance training in rats treated with nandrolone decanoate, an androgenic anabolic steroid. Eighteen‐week‐old male Wistar rats (N = 32) were divided into two groups (

Wear‐Activated Surface Engineering of Thermoplastic Polyurethane/Graphene Nanoplatelet Nanocomposites for Ice Friction Control

Polymer Composites, EarlyView.
Wear‐activated surface engineering of TPU/GNP nanocomposites through improved filler dispersion and interfacial anchoring of functionalized graphene nanoplatelets, leading to finer post‐abrasion textures and enhanced ice traction. ABSTRACT Graphene‐reinforced thermoplastic polyurethane (TPU) composites offer a promising route for developing ...

Identification of Novel CD52+ Fibroblasts in Nodular Prostatic Hyperplasia

The Prostate, EarlyView.
ABSTRACT Background Benign prostatic hyperplasia (BPH) and lower urinary tract symptoms are strongly associated with chronic prostate inflammation and stromal remodeling, yet the stromal cell programs that emerge during inflammatory, nodular remodeling remain incompletely defined. A Toxoplasma gondii infection model produces persistent inflammation and

Quantifying wedge-ice volumes in yedoma and thermokarst basin deposits [PDF]

, 2014
Wedge-ice volume (WIV) is a key factor in assessing the response of ice-rich permafrost landscapes to thaw and in quantifying deep permafrost soil carbon inventories.

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

Small, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...
