Wire‐supercapacitors have drawn extensive attentions as a promising candidate for future wearable electronic devices. However, the relative lower energy densities and imperfect physical properties (e.g., length, tenacity, flexibility, and stability) seriously hinder their real applications as energy storage devices in…
Nanocrystal (NC) morphology, which decides the number of active sites and catalytic efficiency, is strongly determined by the gases involved in synthesis, treatment, and reaction. Myriad investigations have been performed to understand the morphological response to the involved gases. However, most prior work is limit…
Multilayer graphene (MLG) grown by chemical vapor deposition (CVD) is a promising material for electronic and optoelectronic devices. Understanding the stacking configuration and interlayer coupling of MLGs is technologically relevant and of importance for the device applications. Here, we reported a kind of twisted M…
This paper reports on the epitaxial growth of hexagonal boron nitride (hBN) films on sapphire substrates in a cold wall chemical vapor deposition (CVD) system where different sapphire nitridation and hBN growth temperatures were employed. A thin and amorphous nitridated layer was formed at a low temperature (850 C), w…
We report on the design and operation of a 1D magneto-granular phononic crystal composed of a chain of steel spherical beads on top of permanent magnets. The magnetic field of the permanent magnets induces forces in the granular structure. By changing its strength, we can tune the dynamic response of the granular stru…
The semi-classical approach leading to the Thomas-Fermi (TF) model provides a simple universal thermodynamic description of the electronic cloud surrounding the nucleus in an atom. This model is known to be exact at the limit of $Z\rightarrow\infty$, i.e., infinite nuclear charge, at finite density and temperature. Mo…
In this letter we study the valley degeneracy splitting of the transition-metal dichalcogenides monolayer by first-principles calculations. The local magnetic moments are introduced into the system when the transition-metal atoms are adsorbed to the monolayer surface. Zeeman effect arising from the local magnetic mome…
Understanding metabolism and dynamic biological events in cells, as well as physiological functions and pathological changes in organisms, is the major goal of biological investigations. It will improve our capability to diagnose and treat diseases, and will enhance personalized medicine. Fluorescence imaging is a pow…
TensorFlow is a machine learning system that operates at large scale and in heterogeneous environments. Its computational model is based on dataflow graphs with mutable state. Graph nodes may be mapped to different machines in a cluster, and within each machine to CPUs, GPUs, and other devices. TensorFlow supports a v…
A frequency-dependent dual-functional coding metasurface is proposed at terahertz frequencies using two layers of metamaterial structures, each of which is responsible for the independent control of reflection phases at two distinct frequencies. The zero interference between the functionalities at the lower and higher…
Element doping allows manipulation of the electronic properties of 2D materials. Enhanced transport performances and ambient stability of black-phosphorus devices by Te doping are presented. This provides a facile route for achieving airstable black-phosphorus devices.
Science is nowadays directed towards application; however, the path from basic to applied research has been proven sometimes difficult. This is the case of the titanium dioxide nanotube layers (TNTs), discovered more than a decade ago; immediately after being reported, it has been predicted that they would give miracu…

We develop an analytical framework for distribution of popular content in an\nInformation Centric Network (ICN) that comprises of Access ICNs, a Transit ICN\nand a Content Provider. Using a generalized Zipf distribution to model content\npopularity, we devise a game theoretic approach to jointly determine caching\nand…
use classical molecular dynamics and quantum chemical simulations to describe water molecules inside of the HIV-1 neutralizing antibody 2G12 with enough accuracy to model ligand affinity and dynamics. The results indicate that D-fructose's strong affinity to the antibody is partly due to the good retentiveness of solv…
A reliable set of force-field parameters is a crucial prerequisite for molecular mechanics simulations. On page 2349 (DOI: 10.1002/jcc.24457), Ruixing Wang, Mikhail Ozhgibesov, and Hajime Hirao present a force-field parameterization scheme called partial Hessian fitting that allows the derivation of force constant par…
Global configuration variables such as VASP_PSP_DIR and MAPI_KEY are now stored in "~/.pmgrc.yaml". If you are setting these as environmental variables right now, you can easily transition to the new system using
The synthesis of SZr-SBA-15 catalsyt was prepared by using urea hydrolisis method. SBA-15 incoporated with sulfated zirconia was prepared by reacting SBA-15 with Zirkoniumoxychloride and urea at 90oC to form ZrO2-SBA-15. Then H2SO4 was added to ZrO2-SBA-15 at room temperature to form SZr-SBA-15. This SZr-SBA-15 cataly…
E structure and optical constants of the dilute Boron-Indium quaternary alloy BxInyGa1−x−yN lattice matched to GaN have been investigated using the density functional theory calculations within Full-Potential Linearized Augmented Plane Wave method with x and y concentrations varying up to 0.187. The exchange-correlati…
Heat sinks are being considered in many advanced heat transfer applications including automotive and stationary fuel cells as well as cooling of electronic devices. However, there are innumerable fundamental issues in the fields of heat transfer and fluid mechanics perspectives which remains unresolved. The present re…
