Bioinspired Mechanosensitive Organic Artificial Neuron With Programmable Excitatory and Inhibitory Responses via Nonlinear Mechano‐Electrochemical Coupling

open access: yesAdvanced Materials, EarlyView.
Organic artificial neurons couple mechanical deformation and ionic environments through nonlinear mechano‐electrochemical dynamics. Mechanical strain and electrolyte concentration reshape their nonlinear electrical characteristics, programming excitatory or inhibitory spiking responses that mimic mechanosensitive biological neurons and enable ...

Research progress on the role and mechanism of circadian clock gene PER1 in the occurrence and development of multiple diseases

open access: yesFrontiers in Immunology
Circadian rhythm, an inherent 24-hour periodic rhythm in organisms, is regulated by circadian clock genes. As a key component of the transcription-translation feedback loop, the core circadian gene period (PER) 1, not only maintains circadian rhythm ...

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

open access: yesAdvanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

open access: yesAdvanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Bacteriological assessment of freshly slaughtered chicken and a trial for Improvement

open access: yesAssiut Veterinary Medical Journal, 2006
Fifty samples of fresh whole chicken carcasses, breast, thigh, fillets and giblets were examined bacteriologically for Aerobic Plate Count (APC), coliforms count (MPN), Enterobacteriaceae count, Staphylococcus aureus count and Salmonella were.

"Secondary maxima in ozone profiles"

open access: yes, 2021
Ozone profiles from balloon soundings as well as SAGEII ozone profiles were used to detect anomalous large ozone concentrations of ozone in the lower stratosphere. These secondary ozone maxima are found to be the result of differential advection of ozone-

Atmosphere-Ocean Ozone Exchange – A Global Modeling Study of Biogeochemical, Atmospheric and Water-Side Turbulence Dependencies [PDF]

open access: yes, 2009
The significance of the removal of tropospheric ozone by the oceans, covering ~2/3 of the Earth's surface, has only been addressed in a few studies involving water tank, aircraft, and tower flux measurements.

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

open access: yesAdvanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

The Translational Medicine Regarding Ozone in Saline Solutions. Comment on Armeli et al. Ozone Saline Solution Polarizes Microglial Cells Towards an Anti-Inflammatory Phenotype. Molecules 2025, 30, 3932

open access: yesMolecules
This commentary critically evaluates the translational relevance of a recent study investigating the effects of ozonated saline solution (O3SS) on microglial and endothelial cell models. While the original research proposes potential antioxidant and anti-
