Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

Advanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels

Advanced Science, EarlyView.
Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

Interleukin‐1α Mediates Pancreatic Fibroblast Activation, Regulates Immune Cell Recruitment and Fibrosis in Acute and Chronic Pancreatitis

Advanced Science, EarlyView.
During pancreatitis, IL‐1α is released from necrotic acinar cells. In response to IL‐1α, pancreatic fibroblasts release chemokines and cytokines that regulate the recruitment of immune cells to the damaged organ. Furthermore, IL‐1α primes fibroblasts, resulting in increased tissue fibrosis during chronic pancreatitis.

Myocardial expression and redistribution of GRKs in hypertensive hypertrophy and failure [PDF]

The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2004
AbstractG‐protein‐coupled receptor kinases (GRKs) are involved in cardiac hypertrophy and failure. But their temporal expression and cellular localization during the development of hypertrophy and its transition to failure remains to be investigated. In this study, we determined the expression and subcellular distribution of GRK2, GRK3, GRK5, and GRK6 ...

Cell-based and isoform-selective G protein-coupled receptor kinase assays for comprehensive inhibitor evaluation

Communications Biology
G protein-coupled receptor (GPCR) signaling is regulated by four ubiquitously expressed GPCR kinase isoforms (GRKs), namely GRK2, GRK3, GRK5, and GRK6. Overexpression of individual GRKs occurs in diseases like cancer and heart failure, prompting a search

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

Advanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Die Aza‐Büchner–Curtius–Schlotterbeck‐Reaktion: Selektive Bildung Quartärer Kohlenstoffzentren

Angewandte Chemie, EarlyView.
Wir stellen die Aza‐Büchner–Curtius–Schlotterbeck‐(ABCS)‐Reaktion vor: eine milde, katalysatorfreie Methode zur Homologierung von Aryliminen. Im Gegensatz zum traditionellen BCS‐Mechanismus durchläuft das Diazo‐Intermediat eine selektive C─C‐Insertion zur Bildung eines quartären Zentrums.
