All‐solid‐state batteries (ASSBs) with alloy anodes are expected to achieve high energy density and safety. However, the stability of alloy anodes is largely impeded by their large volume changes during cycling and poor interfacial stability against solid‐state electrolytes. Here, a mechanically prelithiation aluminum foil (MP‐Al‐H) is used as an anode to construct high‐performance ASSBs with sulfide...
Colloidal semiconductor CdSe nanoplatelets (NPLs) feature ultranarrow and anisotropic emissions. However, the optical performance of blue‐emitting NPLs is deteriorated by trap states, currently exhibiting tainted emissions and inferior photoluminescence quantum yields (PLQYs). Here, near trap‐free blue‐emitting NPLs are achieved by the controlled growth of the core/crown. Deep trap states in NPLs...
Being a lightweight material with high design freedoms, there are increasing research interests in microlattice metamaterials as sound absorbers. However, thus far, microlattices are limited to one sound dissipation mechanism, and this inhibits their broadband absorption capabilities. Herein, as opposed to improving performances via the addition of features, a dissipation mechanism is subtractively...
Metallic Bi, as an alloying‐type anode material, has demonstrated tremendous potential for practical application of potassium‐ion batteries. However, the giant volume expansion, severe structure pulverization, and sluggish dynamics of Bi‐based materials result in unsatisfied rate performance and unstable cycling stability. Here, 2D bismuth@N‐doped carbon sheets with BiOC bond and internal void space...
Although rechargeable zinc‐ion batteries are promising candidates for next‐generation energy storage devices, their inferior performance at subzero temperatures limits their practical application. Here, a strategy to destroy the H‐bond network by adding synergistic chaotropic regents is reported, thus reducing the freezing point of the aqueous electrolyte below −90 °C. Owing to the synergistic chaotropic...
Achieving efficient conversion of carbon dioxide (CO2) to formic acid (HCOOH) at mild conditions is a promising means to reduce greenhouse gas emission and mitigate the energy crisis. Herein, spin‐polarized density functional theory calculations with van der Waals corrections (DFT+D3) are performed to analyze the catalytic activity of seven metals (Ti, Fe, Ni, Cu, Zn, In, and Sn) anchored on a tungsten...
As a typical perovskite‐type crystal, polyhedral strontium titanate (SrTiO3) has shown anisotropic charge transport behavior in recent studies, however, the carrier transportation and transition of which has not been explained very clearly. This work present the existence of Sr and O divacancies in the novel rhombicuboctahedron SrTiO3 micro/nano particles (Sr1−xTiO3−x/TiO2−x) with exposing (100),...
Van der Waals semiconducting heterostructures, known as stacks of atomically thin transition‐metal dichalcogenide (TMD) layers, have recently been reported as new quantum materials with fascinating optoelectronic properties and novel functionalities. These discoveries are significantly related to the interfacial carrier dynamics of the excited states. Carrier dynamics have been reported to be predominantly...
The catalytic activity and selectivity of single‐atom sites catalysts is strongly dependent on the supports structure and central metal coordination environment. However, the further optimization of electronic configuration to improve the catalytic performance is usually hampered by the strong coordination effect between the support and metal atoms. Herein, it is discovered that enzyme‐mimicking catalytic...
Lead‐free perovskites have gained much interest for photovoltaic and optoelectronic applications. But instability and low quantum efficiency significantly limit their prospects for future applications. Here, a general route is reported to synthesize highly stable lead‐free perovskites on a large scale with remarkably enhanced quantum efficiency. Two typical vacancy‐ordered double perovskites (Cs2ZrCl...
Si1−xGex is a key material in modern complementary metal‐oxide‐semiconductor and bipolar devices. However, despite considerable efforts in metal‐silicide and ‐germanide compound material systems, reliability concerns have so far hindered the implementation of metal‐Si1−xGex junctions that are vital for diverse emerging “More than Moore” and quantum computing paradigms. In this respect, the systematic...
This study presents the first messenger RNA (mRNA) therapy for metastatic ovarian cancer and cachexia‐induced muscle wasting based on lipid nanoparticles that deliver follistatin (FST) mRNA predominantly to cancer clusters following intraperitoneal administration. The secreted FST protein, endogenously synthesized from delivered mRNA, efficiently reduces elevated activin A levels associated with aggressive...
Nanoparticle surfactants (NPSs) offer a powerful means to stabilize the oil‐water interface and construct all‐liquid devices with advanced functions. However, as the nanoparticle size decreases to molecular‐scale, the binding energy of the NPS to the interface reduces significantly, leading to a dynamic adsorption of NPS and “liquid‐like” state of the interfacial assemblies. Here, by using the host‐guest...
The rational design for transition metals‐based carbon nano‐materials as efficient electrocatalysts still remains a crucial challenge for economical electrochemical hydrogen production. Carbon nanotubes (CNTs) as attractive electrocatalysts are typically activated by non‐metal dopant to promote catalytic performance. Metals doping or metal/non‐metal co‐doping of CNTs, however, are rarely explored...
The commercialization of lithium–sulfur batteries with ultra‐high theoretical energy density is restricted mainly by the notorious polysulfides “shuttle effect” and slow Li2S redox reaction kinetics. A sulfur host material with high catalytic activity and high conductivity is greatly desired to improve its electrochemical performance. Herein, a sulfur host material, etched cotton@petroleum asphalt...
Passivation is a popular method to increase power conversion efficiency (PCE), reduce hysteresis related to surface traps and defects, and adjust mismatched energy levels. In this paper, an approach is reported using ammonium chloride (AC) to enhance passivation effects by controlling chlorine (Cl) and ammonium ions (NH4+) on the front and back side of tin oxides (SnO2). AC pre‐treatment is applied...

Multiple crystal surface exposure gives SrTiO3 micro/nano crystal better photocatalytic performance. In addition to the exposed crystal surface, the vacancy is vitally important. In article number 2202659, Li‐zhu Wu, Dongping Duan, and co‐workers investigate the dynamic formation mechanism of atomic vacancies of SrTiO3 crystal deeply, and more importantly, the Sr‐O di‐vacancies...
