High‐Throughput Screening Methods
In article number 2204520, Lydia Helena Wong and co‐workers discover an efficient ternary Mn‐based spinel oxide (Fe0.3Co1.2Mn1.5O4) for oxygen evolution reaction (OER) by employing high‐throughput screening methods. The high OER catalytic performance originates from the multiple active sites in various geometric sites, i.e., Co2+ in tetrahedral‐ and Mn3+ in octahedral‐...

Interactions of Preosteoblasts
Physical patterns are potential surface cues for promoting osteogenic differentiation of stem cells and improving osseointegration of orthopedic implants. Fluidic force microscopy and atomic force microscopy are used to quantitatively investigate the early interaction of preosteoblasts with 3D‐printed patterns having different pillar heights and osteogenic properties...
Isolation‐Free Extracellular Vesicle Analysis
Tony Hu and co‐workers develop a rapid in situ copper nanoshell growth protocol using a gold nanorod seed enhanced plasmonic scattering, as the nanorod lattice structure promotes monocrystalline growth to generate geometries with superior plasmonic properties. Correspondingly, they show that a non‐disruptive copper nanoshell‐enhanced immunoassay (Cu‐NEI)...
The use of nanofabricated materials is being explored for the potential in crop disease management. Chemically synthesized micronutrient nanoparticles (NPs) have been shown to reduce crop diseases; however, the potential of biogenic manganese NPs (bio‐MnNPs) in disease control is unknown. Here, the potential and mechanism of bio‐MnNPs in suppression of watermelon Fusarium wilt, caused by Fusarium oxysporum...
Exploiting active and stable non‐precious metal electrocatalysts for alkaline hydrogen evolution reaction (HER) at large current density plays a key role in realizing large‐scale industrial hydrogen generation. Herein, a self‐supported microporous Ni(OH)x/Ni3S2 heterostructure electrocatalyst on nickel foam (Ni(OH)x/Ni3S2/NF) that possesses super‐hydrophilic property through an electrochemical process...
Chloramphenicol (CAP) has long been used extensively in agriculture and is severely toxic to the biological environment. Microwave catalysis appears a promising method for soil remediation due to its fast and effective heat transfer, but it is challenging to prepare catalysts with good electromagnetic wave absorption and robust catalytic activity. In this study, atomically dispersed Fe on three‐dimensional...
β‐Ag2Te has attracted considerable attention in the application of electronics and optoelectronics due to its narrow bandgap, high mobility, and topological insulator properties. However, it remains a significant challenge to synthesize 2D Ag2Te because of the non‐layered structure of Ag2Te. Herein, the synthesis of large‐size, ultrathin single crystal topological insulator 2D Ag2Te via the van der...
Durable glioblastoma multiforme (GBM) management requires long‐term chemotherapy after surgery to eliminate remaining cancerous tissues. Among chemotherapeutics, temozolomide is considered as the first‐line drug for GBM therapy, but the treatment outcome is not satisfactory. Notably, regorafenib, an oral multi‐kinase inhibitor, has been reported to exert a markedly superior effect on GBM suppression...
Water/Methanol Coelectrolysis
NiCo2S4 is developed through electrochemical deposition on carbon cloth, with the surface magnetism fine‐tuned. The surface spin enhanced NiCo2S4 electrodes possess high stable bifunctional performance even in high current density in water/methanol coelectrolysis system. Hydrogen and value‐added formate are harvested on both sides of the electrodes in the membrane‐less...

All‐inorganic CsPbI3 perovskite solar cells (PSCs) have been extensively studied due to their high thermal stability and unprecedented rise in power conversion efficiency (PCE). Recently, the champion PCE of CsPbI3 PSCs has reached up to 21%; however, it is still much lower than that of organic–inorganic hybrid PSCs. Interface modification to passivate surface defects and minimize charge recombination...
