Th. use of gas diffusion electrode(GDE)based flow cell can realize industrial-scale CO_(2) reduction reactions(CO_(2)RRs).Controlling local CO_(2) and CO intermediate diffusion plays a key role in CO_(2)RR toward multi-carbon(C_(2+))*** th.s work,local CO_(2) and CO intermediate diffusion th.ough.th. catalyst layer(CL)was investigated for improving CO_(2)RR toward C_(2+)*** gas permeability tests and finite element simulation results indicated CL can balance th. CO_(2) gas diffusion and residence time of th. CO intermediate,leading to a sufficient CO concentration with.a suitable CO_(2)/h.(2)O supply for h.gh.C_(2+)*** a result,an excellent selectivity of C_(2+)products~79%at a h.gh.current density of 400 mA·cm^(-2) could be obtained on th. optimal 500 nm Cu CL(Cu500).Th.s work provides a new insigh. into th. optimization of CO_(2)/h.(2)O supply and local CO concentration by controlling CL for C_(2+)products in CO_(2)RR flow cell.

Early stroke prediction is vital to prevent damage. A stroke h.ppens wh.n th. blood flow to th. brain is disrupted by a clot or bleeding, resulting in brain death.or injury. h.wever, early diagnosis and treatment reduce long-term needs and lower h.alth.costs. We aim for th.s research.to be a mach.ne-learning meth.d for forecasting early warning signs of stroke. Th. meth.dology we employed feature selection tech.iques and multiple algorith.s. Utilizing th. XGboost Algorith., th. research.findings indicate th.t th.ir proposed model ach.eved an accuracy rate of 96.45%. Th.s research.sh.ws th.t mach.ne learning can effectively predict early warning signs of stroke, wh.ch.can h.lp reduce long-term treatment and reh.bilitation needs and lower h.alth.costs.
