Few-layered boron carbon nitride nanosheets are synthesized by a simple and environmentally friendly process. The BCN nanosheets have 2-6 atomic layers with high surface area and show enhanced storage performance in lithium batteries, as well as a stable capacity of ~100 mA h g(-1) at 2 A g(-1) for 5000 cycles.

We introduce a novel methodology to formally specify complex multiagent systems. Our approach allows us to redefine computational problems in terms of agents that perform certain tasks. In our view, a system is formed by the combination of atomic and complex agents. Atomic agents are in charge of executing atomic tasks while complex agents reunite and summarize the properties of their underlyin...

nanotechnology is the study of manipulating matter on an atomic and molecular scale. generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension size from 1 to 100 nanometers .  carbon nanotubes have great potentials for novel applications in industry, drug delivery system and many other uses. in this work after purification, multiwa...

The intensive need of atomic data is expanding continuously in a wide variety of applications (e.g, fusion energy and astrophysics, laser-produced, plasma researches, and plasma processing).This paper will introduce our ongoing research work to build a comprehensive, complete, up-to-date, user friendly and online atomic Database Management System (DBMS) namely called AIMS by using SQLite (http:...

Individual rhodopsin molecules have been resolved with atomic force microscopy as both monomers and various oligomeric organizations that are sensitively dependent upon the physical state of membranes and environmental conditions. In intact native disk membranes, rhodopsin molecules are observed as randomly dispersed monomers and small oligomers. In reconstituted rhodopsin-DPPC (dipalmitoylphos...

We study the physical implementation of the photon-Carnot engine (PCE) based on the cavity quantum electrodynamics system [M. O. Scully, M. Suhail Zubairy, G. S. Agarwal, and H. Walther, Science 299, 862 (2003)]. Here we analyze two decoherence mechanisms for the more practical systems of PCE, the dissipation of photon field, and the pure dephasing of the input atoms. As a result we find that (...

In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index,  reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determined by graphite furnace atomic absorption spectrophotometer. The result showed...

We report on a precision measurement of gravitational acceleration using ultracold strontium atoms confined in an amplitude-modulated vertical optical lattice. An uncertainty Δg/g ≈ 10(-7) is reached by measuring at the 5th harmonic of the Bloch frequency. The value obtained with this microscopic quantum system is consistent with the one measured with a classical gravimeter. Using lattice modul...

We report results of glass transition (T(g)) measurements for polymer thin films using atomic force microscopy (AFM). The AFM mode, shear modulation force microscopy (SMFM), involves measuring the temperature-dependent shear force on a tip modulated parallel to the sample surface. Using this method we have measured the surface T(g) of thin (17-500 nm) polymer films and found that T(g) is indepe...
