A biomimetic Z-scheme photocatalyst exhibits dramatically enhanced photocatalytic activity for H<sub>2</sub> production, driven by a tandem solid-state electron flow.
Improved properties arise in transition metal dichalcogenide (TMDC) materials when they are stacked onto insulating hexagonal boron nitride (h-BN). Therefore, the scalable fabrication of TMDCs/h-BN heterostructures by direct chemical vapor deposition (CVD) growth is highly desirable. Unfortunately, to achieve this experimentally challenging. Ideal substrates for h-BN growth, such as Ni, become sulfides during synthesis process. This leads decomposition pregrown film, and thus no...
Twinned growth behaviour in the rapidly emerging area of two-dimensional nanomaterials still remains unexplored although it could be exploited to fabricate heterostructure and superlattice materials. Here we demonstrate how one can utilize twinned relationship between two materials construct vertically stacked heterostructures. As a demonstration, achieve 100% overlap transition metal dichalcogenide layers constituting ReS2/WS2 vertical heterostructure. Moreover, crystal size structure is an...
The idea flat surface, superb thermal conductivity and excellent optical transmittance of single-layer graphene promise tremendous potential for as a material transparent defoggers. However, the resistance defoggers made from conventional transferred increases sharply once both sides film are covered by water molecules which, in turn, leads to temperature drop that is inefficient fog removal. Here, direct growth large-area continuous films on quartz reported, first practical defogger...
We investigate how common ownership affects welfare in a vertically related market. Although mitigates the double marginalization problem and improves welfare, it restricts competition among downstream firms harms welfare. find that whether is welfare‐improving depends on degree of competitiveness Common more likely to improve when there are fewer greater product differentiation. In other words, may market weak.

The eco-friendly processing of conjugated polymer binder for lithium-ion batteries demands improved solubility by introducing functional moieties, while this strategy will concurrently sacrifice conductivity. Employing the polyfluorene-based poly(2,7-9,9 (di(oxy-2,5,8-trioxadecane))fluorene) (PFO), soluble in water-ethanol mixtures, a novel approach is presented to solve trade-off, which features integration aqueous solution with subsequent controlled thermal-induced cleavage solubilizing...
The self-limited chemical vapor deposition of uniform single-layer graphene on Cu foils generated significant interest when it was initially discovered. Soon after, the fabrication real found to need extremely precise control growth conditions. Slight deviations terminate self-limiting homogeneous growth, inevitably leading multilayer formation. Here we propose an innovative way utilize liquid metals resolve this thorny problem. In stark contrast low carbon solubility in solid (e.g., Cu),...
Magnetite (Fe3O4) is an attractive electrode material due to its high theoretical capacity, eco-friendliness, and natural abundance. However, commercial application in lithium-ion batteries still hindered by poor cycling stability low rate capacity resulting from large volume expansion conductivity. We present a new approach which makes use of supercritical carbon dioxide efficiently anchor Fe3O4 nanoparticles (NPs) on graphene foam (GF), was obtained chemical vapor deposition single step....

In this work, a planar model electrode method has been used to investigate the structure–activity relationship of multiple noble and 3d metal catalysts for cathode reaction Li–O2 battery. The result shows that battery performance (discharge/charge overpotential) strongly depends not only on type but also morphology discharge product (Li2O2). Specifically, according electrochemical characterization scanning electron microscopy (SEM) observation, metals (Pd, Pt, Ru, Ir, Au) show excellent...

Palladium-encapsulated covalent organic frameworks (Pd/COFs) have garnered enormous attention in heterogeneous catalysis. However, the dominant ex situ encapsulation synthesis is tedious (multistep), time-consuming (typically 4 days or more), and involves use of noxious solvents. Here we develop a mechanochemical strategy that enables one-step, time-efficient, environmentally benign Pd/COFs. By ball milling COF precursors along with palladium acetate (Pd(OAc)2) one pot under air at room...
