We report a theoretical study showing that by utilizing the illumination of an external laser, the Surface Plasmon Polaritons (SPP) signals on the graphene sheet can be modulated in the sub-micron scale. The SPP wave can propagate along the graphene in the middle infrared range when the graphene is properly doped. Graphene's carrier density can be modified by a visible laser when the graphene s...

This paper deals with the design of novel sub-1-V bandgap reference circuit using only MOS transistors in 0.18 μm CMOS technology, for a supply voltage of 1.8V. The circuit produces a voltage reference of 466.5 mV at 27C with a temperature coefficient of 28.4 ppm/C in the range of -20 to +120C. The power supply rejection of circuit is -30 dB at 8 KHz and this rejection further increase to -50 d...

In this paper we give three sub-cubic cost algorithms for the all pairs shortest distance (APSD) and path (APSP) problems. The rst is a parallel algorithm that solves the APSD problem for a directed graph with unit edge costs in O(log 2 n) time with O(n p logn) processors where = 2:688 on an EREW-PRAM. The second parallel algorithm solves the APSP, and consequently APSD, problem for a directed ...

The doped garnet-type solid electrolytes are attracting great interest due to high ionic conductivity and excellent electrochemical stability against Li metal. However, the thick electrolyte layer rigid nature as well poor interfacial contact huge obstacles for its application in all-solid-state lithium batteries. Herein, an ultrathin flexible 6.4 La 3 Zr 1.4 Ta 0.6 O 12 - (LLZTO-) based with 9...

Magnesium scandium chalcogenide spinels are an important class of materials in Mg anode‐based batteries for energy storage applications. The applications these intriguing not limited to the storage, but use may also be useful solar cells, owing material optical bandgap. So far, all reported synthetic routes involve high‐temperature furnace treatment. Herein, a process which involves facile elec...

The Islamic revival has been observed in the Republic of Dagestan since 90s and is associated with a return to historical roots its peoples, advancing traditional religious cultural values, spread ideologies practices pseudo-Islamic radical extremist groups movements. Traditional values contributed social spiritual integration Muslims Dagestan, while activities political extremists their disint...

The quality of teachers has influence on the quality of educational services. Nurturing theteachers is actually a preoccupation for the educational organizations. The aim of our educationsystem is to produce successful, well-prepared citizens; therefore, careful examination ofindividuals who teach at all levels is a critical step in meeting that goal. The current studyin...

Tin-based perovskites are promising alternative absorber materials for lead-free perovskite solar cells but need strategies to avoid fast tin (Sn) oxidation. Generally, this reaction can be slowed down by the addition of fluoride (SnF2) precursor solution, which also improves layer morphology. Here, work analyzes spatial distribution additive within formamidinium triiodide (FASnI3) films deposi...
