Article Abstract
Excessive greenhouse gas emissions pose a global environmental concern. This paper examines the impact of energy price on China's CO emissions based on an extended STIRPAT (Stochastic Impacts by Regression on Population, Affluence and Technology) structural human ecology model. We utilize Chinese provincial data from 2002 to 2016 and apply the spatial panel data techniques to explicitly consider spatial correlations and spillover effects between observations. Our results show that energy price has a significant negative impact on China's CO emissions after controlling for other economic and energy market factors and spatial correlations of these variables. We identify a significant direct impact of the focal province's price change on CO emissions and an indirect effect exerted by energy price changes in adjacent provinces. Such spatial spillover effects are also observed in other determinants identified in the extended STIRPAT model. We also document a path dependent pattern in China's provincial CO emissions with last period CO emissions influencing the current CO emission levels. Our results show that the negative impact of energy price on CO emissions remains qualitatively the same after incorporating the influence of previous period CO emissions. Our results are also robust to the inclusion of lagged energy price measures, alternative spatial economic models, and alternative spatial weight matrices. Overall, our paper highlights the role of energy market in curbing CO emissions and promoting sustainable economic development.

The persistent presence of the pharmaceutical pollutant nilutamide (NLT) in environmental and biological systems poses a serious threat to ecosystems and human health, necessitating efficient and sustainable detection strategies. In this study, we present a nanoengineered SrWO@MXene electrocatalyst as a high-performance platform for electrochemical sensing. The hybrid material seamlessly integrates the catalytic activity and electrochemical stability of SrWO with the exceptional conductivity and tunable surface chemistry of MXenes, resulting in a synergistic architecture optimized for rapid and selective NLT detection.

The increasing adoption of the Internet of Things (IoT) in energy systems has brought significant advancements but also heightened cyber security risks. Virtual Power Plants (VPPs), which aggregate distributed renewable energy resources into a single entity for participation in energy markets, are particularly vulnerable to cyber-attacks due to their reliance on modern information and communication technologies. Cyber-attacks targeting devices, networks, or specific goals can compromise system integrity.

Focused Ultrasound (FUS) is the concentration of acoustic energy into a small region to produce therapeutic bioeffects. FUS-induced blood-brain barrier opening (BBBO), a strategy to deliver drugs and genes to the brain, also enhances glymphatic drainage, the brain-specific waste clearance system. Thus, FUS BBBO is a promising strategy for addressing the accumulation of neurotoxic solutes that are characteristic of many neurodegenerative diseases.

This study assesses the economic and environmental performance of the supply chain of coking coal and solid recovered fuel-an often overlooked component of product life cycles-to fifteen European steel plants, by investigating different input combinations and transport methods across six scenarios including imports from both within and outside Europe via ship, road, rail, and river. Results showed that Pre-2022, abroad coking coal was cheaper than local coal, but in 2022, a sharp rise in global prices was driven by three key factors: the European ban on Russian imports, the continental energy crisis, and global shipping disruptions, rendering local coal cheaper. By 2023-2024, markets stabilized, reverting toward pre-pandemic levels.
