Powder‐to‐Film Conversion of Nickel Single‐Atom Catalysts into Binder‐Free and Resistant Electrodes

Advanced Materials Interfaces, EarlyView.
A reproducible strategy is reported for fabricating standalone thin‐film electrodes composed of CNx‐supported Ni single‐atom catalysts. The resulting binder‐free electrodes exhibit robust stability, enhanced charge transfer, and superior electrochemical performance, offering scalable opportunities for applications in electrochemistry. ABSTRACT Although

Electronic Structure Modulation Induced by Asymmetric Cu─Ni Centers in a π‐Conjugated Triazine MOF

Advanced Materials Interfaces, EarlyView.
A π‐conjugated H3TATB‐based asymmetric bimetallic CuNi‐MOF was developed as an efficient electrocatalyst for alkaline hydrogen evolution. Benefiting from synergistic Cu–Ni interactions, enhanced charge transfer, and stabilized active sites, CuNi‐MOF delivers superior HER performance with low overpotential, improved kinetics, and 24 h durability.

Flexible Chemiresistive Chitosan‐Glycerol Sensors on Laser‐Induced Graphene Electrodes for Room‐Temperature Ammonia Detection

Advanced Materials Technologies, EarlyView.
Flexible Chitosan‐glycerol sensor integrated with porous laser‐induced graphene (LIG) electrodes enable room‐temperature chemiresistive detection of ammonia (NH3) and proof‐of‐concept detection of fish spoilage. ABSTRACT We report a metal‐free sensor platform combining laser induced graphene (LIG) electrodes with drop‐deposited, glycerol‐plasticized ...

Preconditioning

Acta Numerica, 2015
The computational solution of problems can be restricted by the availability of solution methods for linear(ized) systems of equations. In conjunction with iterative methods, preconditioning is often the vital component in enabling the solution of such systems when the dimension is large. We attempt a broad review of preconditioning methods.

Effect of 4 Weeks Preconditioning with High Intensity Interval Training and Moderate Intensity Continuous Training on Brain Levels of TNF-Α and TLR4 in Male Wistar Rats

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2023
Introduction: Inflammation in the brain is known as neuroinflammation and increases TNF-α (Tumor necrosis factor alpha) secretion and activates the TLR4 (Toll-like receptor 4) pathway.

Daphne mucronata enhances cell proliferation and protects human adipose stem cells against monosodium iodoacetate induced oxidative stress in vitro

Adipocyte, 2020
Mesenchymal stem cells (MSCs) are being used to treat many diseases as they exhibit great regenerative potential. However, MSC’s transplantation sometimes does not yield the maximum regenerative outcome as they are unable to survive in inflammatory ...

Scalable Task Planning via Large Language Models and Structured World Representations

Advanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

LPS preconditioning redirects TLR signaling following stroke: TRIF-IRF3 plays a seminal role in mediating tolerance to ischemic injury

Journal of Neuroinflammation, 2011
Background Toll-like receptor 4 (TLR4) is activated in response to cerebral ischemia leading to substantial brain damage. In contrast, mild activation of TLR4 by preconditioning with low dose exposure to lipopolysaccharide (LPS) prior to cerebral ...

Grounding Large Language Models for Robot Task Planning Using Closed‐Loop State Feedback

Advanced Robotics Research, EarlyView.
BrainBody‐Large Language Model (LLM) introduces a hierarchical, feedback‐driven planning framework where two LLMs coordinate high‐level reasoning and low‐level control for robotic tasks. By grounding decisions in real‐time state feedback, it reduces hallucinations and improves task reliability.

Endogenous “Time Bomb” – Mislocalized Phospholipase A2 as a Critical Mediator of Ultra‐Rapid Mortality in Sepsis and Acute Lung Injury

Advanced Science, EarlyView.
Phospholipase A2 (PLA2), a dormant enzyme, becomes lethal when activated—collapsing lungs in minutes. Our dual therapy (DOPS + varespladib) boosts survival from 0% to >90% in sepsis/ALI. A breakthrough for acute lung injury treatment. ABSTRACT This study reveals that phospholipase A2 (PLA2), normally stable and nontoxic, can be activated specifically ...
