A Conformal Wearable Ultrasound Bioelectronics for Mechanotherapy Reprogramming of Fibroblast Plasticity via Wnt‐FGF10 Axis to Overcome Fibrotic Healing in Urethral Regeneration

open access: yesAdvanced Science, EarlyView.
Fibrotic scarring persistently challenges urethral reconstruction. This study introduces a conformal, wearable ultrasound bioelectronic system that overcomes this by reprogramming fibroblast fate. The device activates a developmental Wnt–FGF10 axis, driving fibroblasts toward a regenerative FGF10+ phenotype that promotes angiogenesis and matrix ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

open access: yesAdvanced NanoBiomed Research, EarlyView.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Changes in speciated PM2.5 concentrations in Fresno, California, due to NOx reductions and variations in diurnal emission profiles by day of week

open access: yesElementa: Science of the Anthropocene, 2019
The San Joaquin Valley in California suffers from poor air quality due to a combination of local emissions and weak ventilation. Over the course of decades, there has been a concerted effort to control emissions from vehicles as well as from residential ...

Ground‐based measurements of NOx and total reactive oxidized nitrogen (NOy) at Sable Island, Nova Scotia, during the NARE 1993 summer intensive [PDF]

open access: yes, 1996
Measurements of NO, NO2, and total reactive oxidized nitrogen (NOy) were added to ongoing measurements of aerosols, CO, and O3 at Sable Island (43°55′N, 60°01′W), Nova Scotia, during the North Atlantic Regional Experiment (NARE) 1993 summer intensive ...
