Abstract Inspired by shape‐morphing organisms in nature, researchers have developed various hydrogels with stimuli‐responsive swelling, shrinking, bending, folding, origami, rolling, twisting, or locomotion. These smart are usually created patterning 4D printing. The shape morphing of allows the fabrication helixing, and rolling microstructures, all which hard to reproduce directly ordinary techniques. More importantly, under external stimuli (e.g., solvent, humidity, temperature, light, pH,...
Abstract Rapid development of perovskite solar cells is challenged by the fact that current semiconductors hardly act as efficient electron transport materials can feature both high mobility and a well-matched energy level to perovskite. Here we show T-carbon, newly emerging carbon allotrope, could be an ideal candidate meet this challenge. By using first-principles calculations deformation potential theory, it found T-carbon semiconductor with direct bandgap 2.273 eV, in conduction band...
Abstract Ever‐increasing demands for superior alloys with improved high‐temperature service properties require accurate design of their composition. However, conventional approaches to screen the such as creep resistance and microstructural stability cost a lot time resources. This work therefore proposes novel high throughput–based strategy accelerate composition selections, by taking Ni‐based superalloys an example. A numerical inverse method is used massively calculate multielement...
Alloying 2D transition metal dichalcogenides has opened up new opportunities for bandgap engineering and phase control. Developing a simple scalable synthetic route is therefore essential to explore the full potential of these alloys with tunable optical electrical properties. Here, direct synthesis monolayer WTe2x S2(1-x) via one-step chemical vapor deposition (CVD) demonstrated. The exhibit two distinct phases (1H semiconducting 1T ' metallic) under different compositions, which can be...
Abstract Fabric‐based materials have demonstrated promise for high‐performance wearable applications but are currently restricted by their deficient mechanical properties. Here, this work leverages the design freedom offered additive manufacturing and a novel interlocking pattern to first time fabricate dual‐faced chain mail structure consisting of 3D re‐entrant unit cells. The flexible structured fabric demonstrates high specific energy absorption strength up 1530 J kg −1 5900 Nm ,...
Phosphorene, a newly discovered member of the two-dimensional nanomaterials family, has attracted intensive interest recently. In this paper, molecular dynamic simulations have been conducted to investigate thermal conductivity and tensile response phosphorene nanosheets containing vacancy defects. Three types, single-vacancy two types divacancies, considered. The simulation results show that both mechanical strength are highly anisotropic largely reduced by Interestingly, effects defects...
The objective of the present study was to investigate friction and wear mechanisms hydrogenated amorphous carbon (a-C:H) films sliding against different counterparts. Friction tests were performed by a reciprocating ball-on-disk tribometer with an applied load 5 N, amplitude mm, frequency Hz, in ambient air at room temperature. coefficient (COF) consistent varied tendency contact area counterparts on also coincided coverage transfer film ball surface. It important point out that counterpart...
Nano-friction of phosphorene plays a significant role in affecting the controllability and efficiency applying strain engineering to tune its properties. So far, friction behavior has not been studied. This work studies single-layer bilayer on an amorphous silicon substrate by sliding rigid tip. For phosphorene, it is found that highly anisotropic, i.e. larger along armchair direction than zigzag direction. Moreover, pre-strain also exhibits anisotropic effects. The increases with direction,...
The lubrication behavior of graphene for diamond-like carbon (DLC) films scratched by a diamond tip is investigated molecular dynamics (MD) simulations. Graphene can efficiently lubricate the DLC film, and its performance be improved increase layer number but degraded defects large size. friction mechanisms during highly depend on normal force, F N. Under small N, superlow f, obtained which represents super-lubrication graphene. f increases due to tribochemical reactions Such happen before...
Abstract The application of few-layered graphene-derived functional thin films for molecular filtration and separation has recently attracted intensive interests. In practice, the morphology nanochannel formed by graphene (GE) layers is not ideally flat can be affected various factors. This work investigates effect channel on water transport behaviors through GE bilayers via dynamics simulations. simulation results show that flow velocity resistance highly depend curvature layers,...
This work investigates the nanoscale friction between diamond-structure silicon (Si) and diamond via molecular dynamics simulation. The interaction interfaces is considered as strong covalent bonds. effects of load, sliding velocity, temperature lattice orientation are investigated. Results show that can be divided into two stages: static kinetic friction. During stage, dramatically affects by changing elastic limit Si. Large deformation induced in Si block, which eventually leads to...
