Abstract As the most promising lead‐free one, tin‐halides based perovskite solar cells still suffer from severe bulk‐defect due to easy oxidation of tin divalent tetravalent. Here, a general and effective strategy is delivered modulate microstructure 2D/3D heterogeneous tin‐perovskite absorber films by substituting FAI with FPEABr in FASnI 3 . The introduction 2D phase can induce highly oriented growth 3D it revealed optimal film that embraces grains locates at surfaces grain boundaries....
Abstract As the most promising lead‐free branch, tin halide perovskites suffer from severe oxidation Sn 2+ to 4+ , which results in unsatisfactory conversion efficiency far what they deserve. In this work, by facile incorporation of methylammonium bromide composition engineering, formamidinium and mixed cations perovskite films with ultrahighly oriented crystallization are synthesized preferential facet (001), that is suppressed obviously declined trap density. MA + ions responsible for...
Developing greener batteries with new chemistries is a formidable challenge, and major focus for years to come. Redox flow are receiving increasing research interest grid-scale electrochemical energy storage owing their unique architecture. However, challenges still remain by low density as well corrosive and/or toxic electrolytes. An anolyte based on aprotic Zn deep-eutectic-solvent, which uses cost, abundant environmentally benign materials, exhibits utilizable concentration of Zn2+ ca....
In this work, an insight into the premature Type IV cracking was undertaken to clarify its mechanisms in Grade 91 steel pipe weldments. High-resolution microscopy observations of as-welded heat-affected zone (HAZ) reveal that commonly recognized fine-grained region susceptible on edge HAZ belongs inter-critical (ICHAZ), rather than (FGHAZ). Instrumented indentation tests uncover ICHAZ is weakest across weld, exhibiting largest displacement and lowest hardness three thermal stages. Localized...
Although substantial evidence reveals that healthy lifestyle behaviors are associated with a lower risk of rheumatoid arthritis (RA), the underlying metabolic mechanisms remain unclear. This study aimed to identify signature reflecting and investigate its observational genetic linkage RA risk. included 87,258 UK Biobank participants (557 cases incident RA) aged 37–73 y complete lifestyle, genotyping, nuclear magnetic resonance (NMR) metabolomics data. A was assessed based on 5 factors: diet,...
Polymethoxylated flavonoids (PMFs) are a subclass of found in citrus fruits that have shown multifunctional biological activities and potential anticancer effects against breast cancer. We studied the absorption, metabolism, species source, toxicity, anti-cancer mechanisms, molecular targets PMFs to better utilize their activity discuss absorption metabolism body, including methylation, demethylation, hydroxylation processes. The mechanisms cancer were also reviewed, estrogen activity,...
In this work, dissimilar rotary inertia friction welds between 422 martensitic stainless steel and 4140 low-alloy were made to fabricate prototype heavy-duty diesel engine pistons. The influence of the welding process post weld heat treatment (PWHT) temperature on interfacial microstructure evolutions corresponding effects mechanical properties 422/4140 evaluated in detail. Carbon diffused from side during PWHT at 650 °C for 1.5 hours, causing formation a hard carbide-rich layer side, softer...
AISI 422 martensitic stainless steel with superior hightemperature performance (oxidation resistance and strength) is under evaluation for replacing current heavy-duty piston crown materials, 4140 microalloyed (MAS) 38MnSiVS5, to fabricate a multimaterial (Refs. 1, 2). This concept further improved power density fuel economy by allowing heavyduty diesel engines operate at higher temperatures pressures (Ref. 3). Joining crowns skirts key manufacturing step this piston. However, the...
We developed a supramolecular tranexamic acid by combining with glycolic acid, resulting in enhanced transdermal permeability and bioactivity, while maintaining low irritancy high biosafety, offering great potential skincare whitening.
