Perpendicular Magnetic Anisotropy
In article number 2308724, Xi Shen, Xiufeng Han, Richeng Yu, and co‐workers proposed a strategy for enhancing perpendicular magnetic anisotropy in yttrium iron garnet (YIG) films with only a tiny lattice mismatch by slight oxygen deficiency, which theoretically originates from the reduction of saturation magnetization and the increase of magnetostriction coefficient...
The development of ultraviolet circularly polarized light (UVCPL) sources has the potential to benefit plenty of practical applications but remains a challenge due to limitations in available material systems and a limited understanding of the excited state chirality transfer. Herein, by constructing hybrid structures of the chiral perovskite CsPbBr3 nanoplatelets and organic molecules, excited state...

2D Selectors
In article number 2310158, Yanpeng Liu, Wanlin Guo, and co‐workers devise a 2D graphene/hBN/WSe2 selector that exhibits outstanding bipolar nonlinearity at room‐temperature. Profiting from well‐designed band alignment and proper tunneling barrier, the selector undergoes direct tunneling at low bias, and Fowler‐Nordheim tunneling at high bias. This proof‐of‐concept demonstration opens...
Rational tailoring of the electronic structure at the defined active center of reconstructed metal (oxy)hydroxides (MOOH) during oxygen evolution reaction (OER) remains a challenge. With the guidance of density functional theory (DFT), herein a dual‐site regulatory strategy is reported to tailor the d‐band center of the Co site in CoOOH via the controlled electronic transfer at the Ru─O─Co─O─Fe bonding...
The evolution of porous membranes has revitalized their potential application in sustainable osmotic‐energy conversion. However, the performance of multiporous membranes deviates significantly from the linear extrapolation of single‐pore membranes, primarily due to the occurrence of ion‐concentration polarization (ICP). This study proposes a robust strategy to overcome this challenge by incorporating...
Adhesive materials have played an essential role in the history of humanity. Natural adhesives composed of low‐molecular‐weight monomers have been overshadowed by modern petroleum‐based glues. With the development of green economy, the demand for eco‐friendly materials has increased. Herein, two natural biocompatible compounds, namely thioctic acid (TA) and malic acid (MA), are selected to prepare...
To improve the sluggish kinetics of the hydrogen evolution reaction (HER), a key component in water‐splitting applications, there is an urgent desire to develop efficient, cost‐effective, and stable electrocatalysts. Strain engineering is proving an efficient strategy for increasing the catalytic activity of electrocatalysts. This work presents the development of Ru‐Au bimetallic aerogels by a simple...
The poor efficiency and low immunogenicity of photodynamic therapy (PDT), and the immunosuppressive tumor microenvironment (ITM) lead to tumor recurrence and metastasis. In this work, TCPP‐TER‐Zn@RSV nanosheets (TZR NSs) that co‐assembled from the endoplasmic reticulum (ER)‐targeting photosensitizer TCPP‐TER‐Zn nanosheets (TZ NSs for short) and the autophagy promoting and indoleamine‐(2, 3)‐dioxygenase...
The fabrication of periodic macroporous (PM) in Nb2O5 via morphological control is crucial for improving the photocatalytic hydrogen evolution efficiency. In this study, Nb2O5 with PM is synthesized using a straightforward colloidal crystal templating approach. This material features an open, interconnected macroporous architecture with nanoscale walls, high crystallinity, and substantial porosity...
The safety, low cost, and high power density of aqueous Zn‐based devices (AZDs) appeal to large‐scale energy storage. Yet, the presence of hydrogen evolution reaction (HER) and chemical corrosion in the AZDs leads to local OH− concentration increasement and the formation of ZnxSOy(OH)z•nH2O (ZHS) by‐products at the Zn/electrolyte interface, causing instability and irreversibility of the Zn‐anodes...
Knee replacement surgery confronts challenges including patient dissatisfaction and the necessity for secondary procedures. A key requirement lies in dual‐modal measurement of force and temperature of artificial joints during postoperative monitoring. Here, a novel non‐toxic near‐infrared (NIR) phosphor Sr3Sn2O7:Nd, Yb, is designed to realize the dual‐modal measurement. The strategy is to entail phonon‐assisted...
Electrocatalytic nitrogen reduction reaction (NRR) paves a sustainable way to produce NH3 but suffering from the relatively low NH3 yield and poor selectivity.

Supported noble metal nanoparticles (NMNPs) are appealing for energy and environment catalysis. To facilitate the loading of NMNPs, in situ reduction of Mn+ on the support with extra reductants/surfactants is adopted, but typically results in aggregated NMNPs with uneven size distributions or blocked active sites of the NMNPs. Herein, the use of cobalt layered double hydroxide (Co‐LDH) is proposed...
Perovskite solar cells (PSCs) have achieved revolutionary progress during the past decades with a rapidly boosting rate in power conversion efficiencies from 3.8% to 26.1%.
