Heterogeneous patterning of blood-brain barrier and adaptive myelination as renewing key in gray and white matter

Background:Development and homeostasis of the brain are enabled through the precise control of the cell microenvironment by the blood-brain barrier(BBB),which interfaces between the brain parenchyma and the lumen of blood microvessels,and by the blood-cerebrospinal fluid barrier,which separates the cerebrospinal fluid from the blood vessels of the choroid plexus(Villabona-Rueda et al.,2019).Here,the focus will be on the BBB,the impairment of which is considered the earliest common denominator in neurovascular diseases.

Cu-Based Materials for Enhanced C_(2+) Product Selectivity in Photo-/Electro-Catalytic CO_(2) Reduction: Challenges and Prospects

引用

Nano-Micro Letters 2024年第4期16卷 25-66页

作者： baker Rhimi Min Zhou Zaoxue Yan Xiaoyan Cai Zhifeng Jiang Institute for Energy Research School of Chemistry and Chemical EngineeringJiangsu UniversityZhenjiang 212013People’s Republic of China School of Materials Science and Physics China University of Mining and TechnologyXuzhou 221116People’s Republic of China

Carbon dioxide conversion into valuable products using photocatalysis and electrocatalysis is an effective approach to mitigate global environmental issues and the energy shortages. Among the materials utilized for catalytic reduction of CO_(2), Cu-based materials are highly advantageous owing to their widespread availability, cost-effectiveness, and environmental sustainability. Furthermore, Cu-based materials demonstrate interesting abilities in the adsorption and activation of carbon dioxide, allowing the formation of C_(2+) compounds through C–C coupling process. Herein, the basic principles of photocatalytic CO_(2) reduction reactions(PCO_(2)RR) and electrocatalytic CO_(2) reduction reaction(ECO_(2)RR) and the pathways for the generation C_(2+) products are introduced. This review categorizes Cu-based materials into different groups including Cu metal, Cu oxides, Cu alloys, and Cu SACs, Cu heterojunctions based on their catalytic applications. The relationship between the Cu surfaces and their efficiency in both PCO_(2)RR and ECO_(2)RR is emphasized. Through a review of recent studies on PCO_(2)RR and ECO_(2)RR using Cu-based catalysts, the focus is on understanding the underlying reasons for the enhanced selectivity toward C_(2+) products. Finally, the opportunities and challenges associated with Cu-based materials in the CO_(2) catalytic reduction applications are presented, along with research directions that can guide for the design of highly active and selective Cu-based materials for CO_(2) reduction processes in the future.

作者： barbara Sternfeld David R.Jacobs Jr. Division of Research Kaiser Permanente Northern CaliforniaOaklandCA 94610USA Division of Epidemiology and Community Health School of Public HealthUniversity of MinnesotaMinneapolisMN 55454USA

In 1985,Public Health Reports published a series of papers prepared for a workshop sponsored by the Centers for Disease Control and Prevention(CDC).1 Building on the seminal work of Jeremy Morris and Ralph Paffenbarger Jr.,who were among the first to use epidemiological methods to study physical activity(PA),2,3 the workshop itself was the result of a growing scientific understanding of the importance of“physical fitness and exercise for improving the health of the public”.
