通过磁控溅射单一四元靶材磁控得到的黄铜矿Cu(In,Ga)Se_(2)(CIGS)太阳电池开发的主要瓶颈是严重的载流子复合,其开路电压非常低.CIGS与钼(Mo)之间不良的缺陷环境是吸收体和界面复合严重的主要原因之一.其中,在背界面处引入的CuGaSe_(2)(CGS)低温缓冲层可以有效地抑制吸收体与背电极在高温磁控过程中的不利界面反应,从而获得高质量的晶体.通过这种背界面工程,不仅可以很好地解决吸收体和界面质量不佳的问题,而且有利于在吸收层中形成梯度带隙结构,从而使深能级InGa缺陷转换为较低能级的VCu缺陷,最终CIGS太阳电池的转换效率达到15.04%.这项工作为直接溅射高效率CIGS太阳电池的产业化提供了一种新的方法.

Acute lung injury（ALI） is a severe inflammatory condition with a high mortality rate, often precipitated by sepsis. The pathophysiology of ALI involves complex mechanisms, including inflammation, oxidative stress, and ferroptosis, a novel form of regulated cell death. This study explores the therapeutic potential of andrographolide（AG）, a bioactive compound derived from Andrographis, in mitigating Lipopolysaccharide（LPS）-induced inflammation and ferroptosis. Our research employed in vitro experiments with RAW264.7 macrophage cells and in vivo studies using a murine model of LPS-induced ALI. The results indicate that AG significantly suppresses the production of pro-inflammatory cytokines and inhibits ferroptosis in LPS-stimulated RAW264.7 cells. In vivo, AG treatment markedly reduces lung edema, decreases inflammatory cell infiltration, and mitigates ferroptosis in lung tissues of LPS-induced ALI mice. These protective effects are mediated via the modulation of the Toll-like receptor 4（TLR4）/Kelch-like ECH-associated protein 1（Keap1）/Nuclear factor erythroid 2-related factor 2（Nrf2） signaling pathway. Molecular docking simulations identified the binding sites of AG on the TLR4 protein(Kd value:-33.5 kcal·mol-1), and these interactions were further corroborated by Cellular Thermal Shift Assay（CETSA） and SPR assays. Collectively, our findings demonstrate that AG exerts potent anti-inflammatory and anti-ferroptosis effects in LPS-induced ALI by targeting TLR4 and modulating the Keap1/Nrf2 pathway. This study underscores AG's potential as a therapeutic agent for ALI and provides new insights into its underlying mechanisms of action.

In this work,a simple fabrication method of germanium-based metasurfaces is proposed,where the deposited Al_(2)O_(3) layer with high selectivity is chosen as the hard mask and retained after the dry etching *** simulation and experimental characterization results verify the feasibility of the fabrication *** experimental study on the fabrication methods of germanium-based metasurfaces is very significant as the meta-atoms with a higher refractive index can achieve 0 to 2πtransmission phase variation with a smaller period under the same thickness-to-period ratio,which is consistent with the requirement of the period miniaturization in some cases.
