Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar *** power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance.

Objective： Mangiferin （MF） is a polyphenol isolated from the root of Anemarrhena asphodeloides Bge.. This study wasaimed to investigate the effects of MF on hyperglycemia in animal models of insulin resistance and streptozotocin（STZ）-induced diabetes. Methods： The diabetes mellitus model was established in mice by receiving a multiplehypodermic injection of hydrocortisone sodium succinate （HCSS）（70 mg/kg） or a single intravenous injection of STZ（130 mg/kg）. Meanwhile MF at different dosage （50, 100 and 200 mg/kg） were oral administrated for consecutive 10days. Data of blood glucose were collected at different time after intraperitoneal injection of insulin （0.5 U/kg） toinvestigate the insulin resistant. As well as the oxygen radical absorbance capacity （ORAC） and superoxide dismutase（SOD） activity of kidney were measured. The in vitro experiment was established to investigate the inhibitory capacity ofMF to α-glucosidase. Results： Oral administration of MF significantly prevented insulin resistance caused by HCSSinjection. STZ-induced diabetic symptoms were also improved, including fasting blood glucose, glycated hemoglobin,plasma triglycerides, hepatic glycogen, kidney SOD and ORAC level. The in vitro experiment demonstrated that MF hadpotent α-glucosidase inhibitory activity. Conclusion： The obtained results demonstrate that MF ameliorates insulinresistance and STZ-induced glucose metabolism disturbance. The MF exerts the protective effects through improving theantioxidant ability, promoting hepatic glycogen synthesis and inhibiting α-glucosidase activity.

Organic solar cells(OSCs)have been developed rapidly in past years,due to the fast evolution of wide-bandgap copoly-mer donors and low-bandgap non-fullerene acceptors[1−9].At present,the highest power conversion efficiencies(PCEs)for single-junction OSCs and tandem OSCs exceed 19%and 20%,respectively[10,11].These OSCs are typically fabricated by us-ing low-boiling-point solvent chloroform(CF)with an effect-ive area<0.1 cm^(2).The doctor-blading deposition is the most advantageous technique to fabricate OSCs with low-boiling-point solvent for upscaling lab cells to industrial-scale mod-ules[12],exhibiting simple operation,low cost,and high materi-al utilization[13−15].Herein,a typical OSC material system PM6:Y6(Fig.1(a))was used to fabricate OSCs modules via doc-tor-blading deposition in ambient condition,and the influ-ence of the ambient temperature and substrate temperature on the film quality was investigated.

以不同浓度镧处理人参发根, qRT-PCR检测人参皂苷合成关键酶基因PgSS,PgDDS和PgβAS的表达水平, HPLC测定人参皂苷含量,探讨镧对人参发根生长及其人参皂苷合成影响的作用机制。镧浓度分别为5.0, 10.0和15.0 mg·L^-1时,促进发根伸长、根毛形成和重量增加, 20.0, 25.0和30.0 mg·L^-1时,抑制发根生长;PgSS和PgDDS基因表达水平对镧呈浓度依赖性变化, 20.0 mg·L^-1时,PgSS和PgDDS基因表达量均显著增加(P<0.05)且达到最大,高于20.0 mg·L^-1时,PgSS和PgDDS基因表达水平随镧浓度升高而降低;镧对PgβAS基因表达无明显影响。镧促进发根中人参皂苷Rb1, Rb2, Rc, Rd, Re, Rg1和总皂苷含量增加,人参皂苷合成积累规律与PgSS和PgDDS基因表达规律一致,当镧浓度为20.0 mg·L^-1时,人参皂苷产量亦达到最高。表明镧可以调节人参发根的生长,通过促进人参皂苷合成关键酶基因PgSS和PgDDS的表达增加人参皂苷的生物合成与积累。

以Mg-Si合金系为例,根据合金基因理论和中心配位原子模型,推导密排六方(HCP)结构B8_(1)-型合金基因浓度的表达式。计算B8_(1)-型有序合金的基因浓度随Si的原子数分数(xSi)和有序度(σ)的变化,阐明B8_(1)-型有序合金的基因浓度随xSi和σ的变化特征。计算B8_(1)-型有序合金和无序Mg((1-x))Six合金随xSi的变化特征。研究结果表明:与无序合金相比,B8_(1)-型有序合金的参数如结合能等变化更大,因此,有序化可提高Mg-Si合金的抗压强度;s和p轨道上的共价电子数(分别为ns和np)随Si的原子数分数的增加而增多,当xSi>0.4时反而减少;共价电子数增多有利于提高Mg-Si合金的抗腐蚀强度,这为智能化制备高强轻质Mg合金指明了方向。
