Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic

Sustainable Live Sound Monitoring and Classification System Enabled by a Triboelectric Nanogenerator and Machine Learning Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance Triboelectric Nanogenerator (TENG) acoustic sensor using polyimine/graphite polypropylene (PI/GP) was developed for real‐time, sustainable sound monitoring and classification. The self‐powered device delivers 25.67 μW output power, 92.7% accuracy with MobileNet V1, and powers a wireless transmission circuit, demonstrating dual ...

High‐Efficiency S‐Scheme Bi4O5IBr/Bi5O7I0.7Br0.3 Double Solid Solution Heterojunction Photocatalyst for Levofloxacin Degradation via Optimized Carrier Dynamics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Particulate Bi4O5 IBr anchored on rod‐like Bi5O7I0.7Br0.3 forms an S‐scheme heterojunction that facilitates charge separation via a built‐in electric field, leading to exceptional photocatalytic activity and stability for LEV degradation. The remediation of antibiotic‐polluted water demands advanced photocatalytic systems with high efficiency and ...

Framing Effects on Public Support and Behavioral Responses to Sustainable Forest Management in South Korea

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Despite South Korea's extensive forest coverage, which accounts for approximately 63% of its total land area, the country imports over 83% of its timber needs and has shown a gradual decline in forest carbon sequestration capacity. The Circular Forest Management Policy (CFMP) addresses these challenges through systematic forest resource ...
