Flexible and ultratransparent conductors based on graphene sheets have been considered as one promising candidate for replacing currently used indium tin oxide films that are unlikely to satisfy future needs due their increasing cost losses in conductivity bending. Here we demonstrate a simple fast electrochemical method exfoliate graphite into thin sheets, mainly AB-stacked bilayered with large lateral size (several several tens of micrometers). The electrical properties these exfoliated...
Abstract Alloys with ultra-high strength and sufficient ductility are highly desired for modern engineering applications but difficult to develop. Here we report that, by a careful controlling alloy composition, thermomechanical process, microstructural feature, Co-Cr-Ni-based medium-entropy (MEA) dual heterogeneous structure of both matrix precipitates can be designed provide an tensile 2.2 GPa uniform elongation 13% at ambient temperature, properties that much improved over their...
Direct formation of high-quality and wafer scale graphene thin layers on insulating gate dielectrics such as SiO(2) is emergent for electronics using Si-wafer compatible fabrication. Here, we report that in a chemical vapor deposition process the carbon species dissociated Cu surfaces not only result top catalytic films but also diffuse through grain boundaries to interface between underlying dielectrics. Optimization parameters leads continuous large-area directly formed The bottom-gated...
Abstract As one of the most important photocatalysts, TiO 2 has triggered broad interest and intensive studies for decades. Observation interfacial reactions between water at microscopic scale can provide key insight into mechanisms photocatalytic processes. Currently, experimental methodologies characterizing anatase are mostly confined to vapor or single molecule chemistry. Here, we investigate reaction nanoparticles in using liquid environmental transmission electron microscopy. A...
Abstract Designing highly conducting metal–organic frameworks (MOFs) is currently a subject of great interest for their potential applications in diverse areas encompassing energy storage and generation. Herein, strategic design which metal–sulfur plane integrated within MOF to achieve high electrical conductivity, successfully demonstrated. The {[Cu 2 (6-Hmna)(6-mn)]·NH 4 } n ( 1 , 6-Hmna = 6-mercaptonicotinic acid, 6-mn 6-mercaptonicotinate), consisting two dimensional (–Cu–S–) plane,...
Abstract The performances of rechargeable batteries are strongly affected by the operating environmental temperature. In particular, low temperatures (e.g., ≤0 °C) detrimental to efficient cell cycling. To circumvent this issue, we propose a few-layer Bi 2 Se 3 (a topological insulator) as cathode material for Zn metal batteries. When is used in combination with an anti-freeze hydrogel electrolyte, capacity delivered at −20 °C and 1 A g −1 1.3 larger than 25 same specific current. Also, 0 |...
Abstract The advancement of laser-induced graphene (LIG) technology has streamlined the fabrications flexible devices. However, ultrafast kinetics triggered by laser irradiation generates intrinsic amorphous characteristics, leading to high resistivity and compromised performance in electronic Healing defects specific patterns is technologically challenging conventional methods. Herein, we report rapid rectification LIG’s topological flash Joule heating milliseconds (referred as F-LIG),...
Lithium metal batteries (LMBs) are regarded as the potential alternative of lithium‐ion due to their ultrahigh theoretical specific capacity (3860 mAh g‐1). However, severe instability and safety problems caused by dendrite growth inevitable side reactions have hindered commercialization LMBs. To solve them, in this contribution, a design strategy soluble lithiophilic covalent organic frameworks (COFs) is proposed. By introducing polyethylene glycol chains, two COFs (CityU‐28 CityU‐29) not...
A contact has been developed to achieve a low specific resistance p-type GaN. The consisted of bi-layer Ni/Au film deposited on GaN followed by heat treatment in air transform the metallic Ni into NiO along with an amorphous Ni–Ga–O phase and large Au grains. as 4.0×10−6 Ω cm2 was obtained at 500 °C. This value optimization thickness temperatures. Below about 400 °C, not completely oxidized. On other hand, temperatures higher than 600 increased because detached from p-GaN amount formed more...
Growing carbon nanotubes (CNTs) by arcing from graphite electrodes does not demand a noble gas atmosphere: water will do! CO and H2 bubbles generated reaction of C vapor with provide quasi-inert atmosphere in which multiwalled grow the cathode. Using cobalt salt solutions instead plain water, authors obtained CNTs filled metallic elemental sulfur (see Figure), potentially useful as nanoprobes for magnetic force microscopy.

Glioblastoma multiforme (GBM) is among the most aggressive of human cancers. Although differentiation therapy has been proposed as a potential approach to treat GBM, mechanisms induced remain poorly defined. Here, we established an model GBM using cAMP activators that specifically directed into astroglia. Transcriptomic and proteomic analyses revealed oxidative phosphorylation mitochondrial biogenesis are involved in GBM. Dibutyryl cyclic AMP (dbcAMP) reverses Warburg effect, evidenced by...

Abstract Inorganic-based micro light-emitting diodes (microLEDs) offer more fascinating properties and unique demands in next-generation displays. However, the small size of microLED chip (1–100 µ m) makes it extremely challenging for high efficiency low cost to accurately, selectively, integrate millions chips. Recent impressive technological advances have overcome drawbacks traditional pick-and-place techniques when they were utilized assembly display, including most broadly recognized...
