In this work, we report a facile, clean, controllable and scalable phase engineering technique for monolayer MoS2. We found that weak Ar-plasma bombardment can locally induce 2H→1T transition in MoS2 to form mosaic structures. These transitions are stabilized by point defects (single S-vacancies) the sizes of induced 1T domains typically few nanometers, as revealed scanning tunneling microscopy measurements. On basis selected-area patterning process, fabricated FETs inducing within metal...
A new type of metabolizable and efficient radiosensitizer for cancer radiotherapy is presented in this study by combining ultrasmall Au nanoclusters (NCs, <2 nm) with biocompatible coating ligands (glutathione, GSH). The nano-construct (GSH-coated Au25 NCs) inherits attractive features both the core (strong radiosensitizing effect) GSH shell (good biocompatibility). It can preferentially accumulate tumor via improved EPR effect, which leads to strong enhancement radiotherapy. After...
Recently, 2D materials exhibit great potential for humidity sensing applications due to the fact that almost all atoms are at surface. Therefore, quality of material surface becomes key point sensitive perception. This study reports an integrated, highly sensors array based on large-area, uniform single-layer molybdenum disulfide with ultraclean Device mobilities and on/off ratios decrease linearly relative varying from 0% 35%, leading a high sensitivity more than 104 . The reversible water...
Monolayer molybdenum disulfide (MoS2) has attracted great interest due to its potential applications in electronics and optoelectronics. Ideally, single-crystal growth over a large area is necessary preserve intrinsic figure of merit but very challenging achieve. Here, we report an oxygen-assisted chemical vapor deposition method for monolayer MoS2. We found that the MoS2 domains can be greatly improved by introducing small amount oxygen into environment. Triangular achieved with sizes up...
2D semiconductors are promising channel materials for field-effect transistors (FETs) with potentially strong immunity to short-channel effects (SCEs). In this paper, a grain boundary widening technique is developed fabricate graphene electrodes contacting monolayer MoS2 . FETs lengths scaling down ≈4 nm can be realized reliably. These graphene-contacted ultrashort exhibit superior performances including the nearly Ohmic contacts and excellent SCEs. This work provides facile route toward...
In this Letter, we report the observation of thermally induced rotation graphene on hexagonal boron nitride (h-BN). After rotation, two stable configurations h-BN with a relative lattice twisting angle 0° (most stable) and 30° (metastable), respectively, were found. Graphene below (above) critical ∼12±2° tends to rotate towards (30°) at temperature >100 °C, which is in line our theoretical simulations. addition, by manipulating annealing flake sizes graphene, moiré superlattices large...
Chronic diabetic wounds are an important healthcare challenge. High concentration glucose, high level of matrix metalloproteinase-9 (MMP-9), and long-term inflammation constitute the special wound environment wounds. Tissue necrosis aggravates formation irregular All above factors hinder healing chronic To solve these issues, a glucose MMP-9 dual-response temperature-sensitive shape self-adaptive hydrogel (CBP/GMs@Cel&INS) was designed constructed with polyvinyl alcohol (PVA) chitosan...
Poor penetration of therapeutic drugs into tumors is a major challenge in anticancer therapy, especially solid tumors, leading to reduced efficacy vivo. In the study, we used new tumor-penetrating peptide, CRGDK, conjugate onto surface doxorubicin encapsulated nanoscale micelles. The CRGDK peptide triggered specific binding neuropilin-1, enhanced cellular uptake and cytotoxicity vitro highly accumulation
An intriguing new Wacker-type oxidation of alkynes catalyzed by PdBr2 and CuBr2 is described, which opens an efficient access to 1,2-diketones using molecular oxygen. Under the optimized conditions, a variety alkynes, including diarylalkynes, arylalkylalkynes, dialkylalkynes, were compatible substrates in this transformation. The mechanism reaction was preliminarily investigated control experiments.

Control of the precise lattice alignment monolayer molybdenum disulfide (MoS 2 ) on hexagonal boron nitride (h‐BN) is important for both fundamental and applied studies this heterostructure but remains elusive. The growth precisely aligned MoS domains basal plane h‐BN by a low‐pressure chemical vapor deposition technique reported. Only relative rotation angles 0° or 60° between are present. Domains with same orientation stitch form single‐crystal, different orientations from mirror grain...
Abstract Dual‐band electrochromic smart windows with dynamic and independent control of near‐infrared (NIR) visible (VIS) light transmittance can notably reduce the carbon footprint buildings improve occupants’ visual thermal comfort. The dual‐band response is often generated by phase transition crystalline materials. However, phase‐transition materials kinetically sluggish, resulting in a long time. Herein, fast‐switching window based on single‐component amorphous porous tungsten oxide...
Two-dimensional (2D) room-temperature chiral multiferroic and magnetic topological materials are essential for constructing functional spintronic devices, yet their number is extremely limited. Here, by using the polar HPP (HPP = 4-(3-hydroxypyridin-4-yl)pyridin-3-ol) as an organic linker transition metals (TM Cr, Mo, W) nodes, we predict a class of 2D TM(HPP)2 organometallic nanosheets that incorporate homochirality, magnetism, ferroelectricity, nodes. The homochirality introduced linkers,...
