Additive engineering is widely utilized to optimize film morphology in active layers of organic solar cells (OSCs). However, the role of additive in film formation and adjustment of film morphology remains unclear at the molecular level. Here, taking high‐efficiency Y6‐based OSC films as an example, this work thus employs all‐atom molecular‐dynamics simulations to investigate how introduction of additives...
Photodynamic therapy (PDT) has promising applications. However, the lethal function of reactive oxygen species (ROS) produced during PDT is typically limited. This restriction is induced by oxygen shortage in the tumor microenvironment due to tumor cell hypermetabolism and reductive chemicals overexpression in tumor tissues. Glutamine (Gln) metabolism is crucial for malignancy development and is closely...
Combining the methanol oxidation reaction (MOR) and hydrogen evolution reaction (HER) within an integrated electrolytic system may offer the advantages of enhanced kinetics of the anode, reduced energy consumption, and the production of high‐purity hydrogen. Herein, it is reported the construction of Ni─MoN nanorod arrays supported on a nickel foam substrate (Ni─MoN/NF) as a bifunctional electrocatalyst...
The low electrical conductivity and the high surface defect density of the TiO2 electron transport layer (ETL) limit the power conversion efficiency (PCE) of corresponding perovskite solar cells (PSCs). Here, the conductivity and defect modulation of the mesoporous TiO2 (mp‐TiO2) ETL via oxygen vacancy (OV) management by the reduction and oxidation treatment are reported. Reduction treatment via reducing...
Deterministic Magnetization Switching
A sunlight‐controlled, non‐volatile, near 180‐degree deterministic magnetization switching is illustrated in Pt/Co/Pt/PN Si heterostructures with a magnetic bias assistant. The perpendicular magnetic anisotropy (PMA) can be regulated via photoelectron‐induced Fermi level altering and corresponding Rashba field change at the Pt/Co interfaces. The sunlight tuning...
Finding an energy‐efficient way of switching magnetization is crucial in spintronic devices, such as memories. Usually, spins are manipulated by spin‐polarized currents or voltages in various ferromagnetic heterostructures; however, their energy consumption is relatively large. Here, a sunlight control of perpendicular magnetic anisotropy (PMA) in Pt (0.8 nm)/Co (0.65 nm)/Pt (2.5 nm)/PN Si heterojunction...
The phototheranostics in the second near‐infrared window (NIR‐II) have proven to be promising for the precise cancer theranostics. However, the non‐responsive and “always on” imaging mode lacks the selectivity, leading to the poor diagnosis specificity. Herein, a tumor microenvironment (TME) activated NIR‐II phototheranostic nanoplatform (Ag2S‐Fe(III)‐DBZ Pdots, AFD NPs) is designed based on the principle...
Si Nanodisk Clusters
In article number 2204883, Kai Chen and co‐workers demonstrate a new type of anapole state termed as extrinsic anapole with mode field spreading across the high‐index all‐dielectric nanodisk clusters, unlike the intrinsic one that is confined within individuals. The extrinsic anapole boosts two‐photon‐induced white‐light emission in Si nanodisk clusters.
Nanoparticle clusters provide new degrees of freedom for light control due to their mutual interaction compared with an individual one. Here, the authors demonstrate theoretically and experimentally a type of optical anapole (a nonradiating state) termed as extrinsic anapole, with mode field spreading across Si nanodisk dimers unlike the intrinsic one that is confined within individual nanodisks....
The development of highly active carbon‐based bifunctional electrocatalysts for both the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is highly desired, but still full of challenges in rechargeable Zn–air batteries. Metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have gained great attention for various applications due to their attractive features of structural...
The properties of separators significantly affect the efficiency, stability, and safety of the lithium‐based batteries. Therefore, the improvement of the separator material is critical. Polyetherketone (PEK) has excellent general properties, such as mechanical strength, chemical stability, and thermal stability. Thus, it is expected to be an optimal separator material. However, its low solubility‐induced...
