Here, a generic approach is proposed for quantifying life-cycle stage-wise carbon intensity of both hydrogen- and electricity-driven energy internets. Life-cycle decarbonization effects on vehicle pathways are compared with traditional vehicles with internal-combustion engines.

The device exhibits exceptional voltage-activated synaptic properties, encompassing features such as short-term and long-term plasticity, alongside notable light-sensitive characteristics that enable diverse light-triggered synaptic functions. Through simultaneous light and electrical voltage signals, we achieve light-enhanced/electrically erasing behavior, light-initiated paired-pulse facilitation (PPF), and learning-forgetting-relearning processes by tuning the 405 nm wavelength optical light. Furthermore, by manipulating charge dynamics through light intensity and duration, we replicate the basic sensing and perception function of the human eyes as a volatile receptor, showing potential for artificial retina applications. The device also demonstrates the capability to track objects and eye movement, holding promise for virtual reality systems.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"45 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report a physical approach using a cold atmospheric plasma (CAP) to target diabetic wounds locally for regulating the inflammatory phase of the wounds. In this paper, a comprehensive analysis of inflammatory factors combined with physical investigations of the helium plasma jet characteristics is conducted. The physical and biological safety and clinical application prospects of the CAP jet for the human body are also analyzed. The results demonstrate for the first time that CAP therapy can stimulate the body’s own inflammatory regulation function to achieve a normal state, rather than excessively interfere in a single target. This involves the inhibition of pro-inflammatory factors in the onset subphase and the promotion of anti-inflammatory factors in the subsequent resolution subphase.

To tackle this, we present a metal-free catalytic sorting method for targeted deconstruction of polyester from post-consumer plastic waste, encompassing textiles, plastic mixtures, and multilayer packaging materials. This method employs N-methylpiperidine, a tertiary amine catalyst in methanol, to depolymerize polyethylene terephthalate (PET). Operating under these conditions (160°C, 1 h), we achieve 100% yields of dimethyl terephthalate and ethylene glycol. This technique also effectively breaks down other polyesters, including polylactic acid, polycarbonate, and polybutylene terephthalate, yielding high-yield monomers at relatively low temperatures. Through comprehensive nuclear magnetic resonance (NMR) analysis, we propose that N-methylpiperidine’s role is in enhancing methanol nucleophilicity and activating PET’s ester bond.
