Given that these devices usually cool down to the sub-ambient temperature range, their performance is critically dependent on the material properties at temperatures below 300 K. Consequently, enhancing the thermoelectric properties of materials at sub-ambient temperature is of paramount importance for advancing cooling technology. Herein, a single-crystalline Mg3Bi2-based material has been prepared and exhibits high electron mobility. As a result, thermoelectric figure-of-merit values of ∼1.05 at 300 K and ∼0.87 at 250 K (along the ab plane) have been achieved, which are superior to commercial n-type Bi2(Te, Se)3. Thermoelectric coolers (single- and double-stage devices) based on the n-type single-crystalline Mg3Bi1.497Sb0.5Te0.003 and p-type (Bi, Sb)2Te3 have been fabricated. The double-stage cooler demonstrates a remarkable maximum cooling temperature difference of ∼106.8 K at the hot-side temperature of 350 K, surpassing the performance of commercial Bi2Te3-based devices. Notably, the Mg3Bi2-based double-stage device exhibits exceptional cyclic stability, maintaining its cooling performance without any observable degradation after approximately 2,000 cycles between the input currents of 1 and 3 A. These findings show that single-crystalline Mg3Bi2 alloys hold great promise for thermoelectric cooling applications.","PeriodicalId":36121,"journal":{"name":"The Innovation","volume":"6 5","pages":"100864"},"PeriodicalIF":33.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105525/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144162566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thalamus, a crucial hub in the brain connectome, has been empirically inferred to maintain consciousness and wakefulness. Here, we investigated thalamic spiking, brain connectivity, consciousness states, and recovery outcomes following deep brain stimulation in 29 patients. Our study reveals that thalamic neuronal activity serves as a marker of consciousness state. Patients diagnosed with vegetative state/unresponsive wakefulness syndrome exhibited less-active neurons, with longer and more variable burst discharges, than those in a minimally conscious state. Furthermore, neuronal profiles in the intralaminar thalamus, the direct stimulation site, predicted whether electrostimulation here improved recovery. Stronger tonic firing was correlated with enhanced thalamocortical connectivity and better recovery outcomes in patients. These findings suggest that thalamic spiking signatures, including single-neuron burst discharge and tonic firing, selectively indicate the representation and alteration of consciousness.","PeriodicalId":36121,"journal":{"name":"The Innovation","volume":"6 5","pages":"100846"},"PeriodicalIF":33.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105493/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144162644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tin dioxide (SnO2) shows a notable ability to electrocatalytically convert CO2 into formate, though its efficiency is significantly limited by its low catalytic activity. Herein, we construct facet-oriented SnO2 nanoflowers all standing on a three-dimensional nickel hollow fiber that exhibits superior CO2-to-formate electrocatalytic performance. A formate selectivity of 94% and stability of 300 h with a current density of 1.3 A cm-2 at -1.1 V (vs. reversible hydrogen electrode [RHE]) are attained under ambient conditions. Notably, an extremely high CO2 single-pass conversion rate of 85% is achieved, outperforming prominent catalysts reported in electrocatalysis. The synergetic combination of the unique nanostructures and their advanced spatial configuration is proposed to be responsible for the facet-oriented SnO2 with a hierarchical structure, providing fully exposed active sites and facilitating mass and charge transfers. Enhanced mass transfer in the hollow fiber electrode verified by electrochemical measurements and well-retained Sn4+ species confirmed by in situ spectroscopy synergistically boost the high CO2 conversion activity. In situ spectroscopy and theoretical calculation results demonstrate that the SnO2(101) facet favors ∗OCHO intermediate formation and ∗HCOOH desorption, leading to high formate selectivity. This study provides a straightforward approach to the precise fabrication of composite hollow fiber electrodes, enabling highly efficient electrocatalytic reactions with gas molecules.","PeriodicalId":36121,"journal":{"name":"The Innovation","volume":"6 6","pages":"100844"},"PeriodicalIF":33.2,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12169250/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144318191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
