The mechanical properties, including the Young's modulus and intrinsic strength, of graphene oxides are investigated by first-principles computations. Structural models both ordered amorphous considered compared. For oxides, is found to vary from 380 470 GPa as coverage oxygen groups changes, respectively. corresponding variations in with comparable smaller at 290–430 GPa. Similarly, also possess higher strength compared ones. As increases, decrease monotonically due breaking sp2 carbon...
Herein, a patterned rod-like CoP@NiCoP core-shell heterostructure is designed to consist of CoP nanowires cross-linked with NiCoP nanosheets in tight strings. The interfacial interaction within the heterojunction between two components generates built-in electric field that adjusts charge state and create more active sites, accelerating transfer improving supercapacitor electrocatalytic performance. unique structure suppresses volume expansion during charging discharging, achieving excellent...
One great challenge for supercapacitor is to achieve high energy capacity and fast charge/discharge rates simultaneously. Porous graphene with large surface area a promising candidate electrode materials of supercapacitor. Using first-principles calculations non-equilibrium Green's function technique, we have explored the formation energies, mechanical properties, diffusion behaviors electrical conductance sheets various hole defects and/or nitrogen doping. Interestingly, pyridinic-like...
The modulation of the electronic structure is effective access to achieve highly active electrocatalysts for hydrogen evolution reaction (HER). Transition-metal phosphide-based heterostructures are very promising in enhancing HER performance but facile fabrication and an in-depth study catalytic mechanisms still remain a challenge. In this work, catalytically inactive n-type CeOx successfully combined with p-type CoP form CoP/CeOx heterojunction. crystalline–amorphous heterojunction...
Heterostructure construction is an effective strategy for enhancing the properties of functional materials.
Semantic segmentation requires a large amount of densely annotated data for training and may generalize poorly to novel categories. In real-world applications, we have an urgent need few-shot semantic which aims empower model handle unseen object categories with limited data. This task is non-trivial due several challenges. First, it difficult extract the class-relevant information class as only few samples are available. Second, since image content can be very complex, suppressed by base...

Electrochemical N2 reduction reaction (NRR) emerges as a highly attractive alternative to the Haber-Bosch process for producing ammonia (NH3) under ambient circumstances. Currently, this technology still faces tremendous challenges due low production rate and Faradaic efficiency, urgently prompting researchers explore efficient electrocatalysts. Inspired by Fe-Mo cofactor in nitrogenase, we report Mo-doped hematite (Fe2O3) porous nanospheres containing Fe-O-Mo subunits enhanced activity...
We study the task of weakly-supervised point cloud semantic segmentation with sparse annotations (e.g., less than 0.1% points are labeled), aiming to reduce expensive cost dense annotations. Unfortunately, extremely annotated points, it is very difficult extract both contextual and object information for scene understanding such as segmentation. Motivated by masked modeling MAE) in image video representation learning, we seek endow power learn from sparsely-annotated points. However,...
Visible light positioning (VLP) is widely believed to be a cost-effective answer the growing demand for indoor positioning. There are two critical elements in VLP: accuracy and real-time ability. Nevertheless, because of nonlinear highly complicated relationship between three-dimensional world coordinate two-dimensional image coordinate, developing an effective VLP location algorithm locate facility using complementary metal–oxide–semiconductor sensor great need. Additionally, due high...

The electronic and transport properties of graphene grain boundaries (GBs) are studied using density functional theory nonequilibrium Green's function method. Most GBs preserve the semi-metal perfect graphene; however, some can open a moderate band gap up to 0.5 eV, which provides potential way for engineering graphene-based materials. Nonequilibrium calculations transmission coefficients showed that conduction channels electrons at Fermi level be totally blocked or reduced due existence...
