Plasma Activate Nitrogen for Efficient Ammonia Synthesis

open access: yesExploration, EarlyView.
This review systematically summarizes the classification and reaction mechanism of plasma, and discusses the synergy between different plasmas and catalytic methods along with energy consumptions in detail, in order to gain a deeper understanding of currently ammonia synthesis strategies.

Move beyond free radical theory of aging

open access: yesiMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Generating Tagged Micro‐ and Nanoparticles of Poly(ethylene furanoate) and Poly(ethylene terephthalate) as Reference Materials

open access: yesMacromolecular Rapid Communications, EarlyView.
We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

open access: yesMed Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

From commons to commoning as resistance efforts to blue injustice: A sociohistorical and ethnographical approach

open access: yesPeople and Nature, EarlyView.
Abstract Over the last 20 years, collaborative efforts have emerged with the intention of going beyond the pure capitalist economy, seeking to generate transformative community‐based changes that guarantee blue equity, fair distribution and well‐being.
