Abstract null null In this paper, a position-sensitive detector (PSD) with an enhanced position detection performance has been proposed using graphene-silicon-on-insulator (GSOI) structure. By introducing the gate manipulation, the separation efficiency and diffusion speed of the photo-induced charges have been greatly improved. We experimentally observe a 10-fold increase in the generated photocurrent and the response time is shorten by around 8 times, compared to the counterpart without modula...

Abstract null null Concavo-convex surface can increase the external surface area and provide multi-directional reflective surface, which has significant advantages in improving the microwave absorbing performance of materials. In this paper, a series of N-doped carbon microsphere composites with concavo-convex surface (NCMCCS) and their preparation method have been reported. The precursors organic-inorganic hybrid microspheres with concavo-convex surface (OHMCS) are synthesized by solvothermal m...

Abstract null null Metal-organic frameworks (MOFs) derived metal/carbon composites are considered as feasible high-performance electromagnetic wave absorption materials and have received considerable attention. Herein, biconical prisms Ni@C composites were fabricated via a simple carbonization of Ni-MOFs template. It was found that the core-shell biconical prisms Ni@C composites achieved an optimization of the impedance matching and an efficient microwave absorption performance by regulating the...

Abstract null null We developed a facile and unique process for preparing boron-doped porous carbon by direct carbonization of a boron-based covalent organic framework (COF-5). Boron oxides, which are formed during the carbonization of COF-5, were readily removed through water treatment of the resulting carbon to obtain boron-doped porous carbon. Thus, boron atoms were successfully incorporated into the carbon matrix. Supercapacitor electrodes made of the fabricated boron-doped carbon exhibited ...

Abstract null null Graphene synthesized via electrochemical exfoliation of graphite is considered to be a simple, fast, and scalable technique. This exfoliation technique leads to the formation of multi-layer graphene sheets with some defects, which is feasible for developing supercapacitor electrodes due to the presence of various pseudocapacitive functionalities. We report the exfoliation of multi-layer graphene via pulse sonication assisted electrochemical exfoliation technique (sonoelectroch...

Abstract null null Carbon sulfur nanothreads (CSNTs) mainly composed of two chiral long alkane chains have been recently fabricated from thiophene by a pressure-induced phase transition in low-temperature, but their mechanical properties remain unexplored. Here, the critical roles of morphology and temperature on the tensile characteristics of CSNTs are for the first time examined using molecular dynamic simulations with a first-principles-based ReaxFF forcefield. It is revealed that CSNTs exhib...

Abstract null null By combining highly resolved Scanning Tunneling Potentiometry with the exceptional sample homogeneity of graphene on SiC epitaxially grown by polymer-assisted sublimation growth, we reveal local variations in the resistance associated with substrate steps. We quantify these variations and show that they are an intrinsic property of graphene on SiC. Furthermore, we trace back their origin to variations in the electronic structure of the interface and, thereby, demonstrate the c...

Abstract null null Accompanied by the increasingly serious disordered electromagnetic radiation to trigger electromagnetic pollution become a new generation source which is harmful and difficult to protect, it is still a enormous challenge to develop a novel microwave absorbing materials (MAM) with low-density and wide absorption band. Here, we propose an advanced strategy to encapsulate red blood cell-like mesoporous carbon spheres with magnetic nanoparticles in terms of the problems of poor im...

Abstract null null Low contact resistance of carbon nanotube (CNT) fibers are fundamental component to improve the electrical transport properties of CNT fibers. To reduce the contact resistance of CNT fibers, we have demonstrated synergistic effect of macroscopic densification in combination with heteroatom doping. Boron and nitrogen atoms were introduced into the hexagonal carbon lattice of the CNTs through judicious combination of high temperature thermal doping and plasma treatment. Chlorosu...
