Graphene oxide (GO) and reduced graphene (rGO) were synthesized from graphite powder to compare the adsorption capacity of GO rGO towards a cationic dye-methylene blue (MB). These nanomaterials analyzed by Fourier Transform-Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), Field Emission Scanning Electron Microscope (FESEM). FTIR results indicated presence larger number oxygenated functional groups in as compared surface suggests conversion rGO. Scattered layers sheets with chunks...
In this work, the performance of Junctionless Double Gate MOSFET for label-free electrical detection biomolecules like enzyme, cell, DNA, etc. has been investigated with help an analytical model. The impact neutral on characteristics n-type Si analyzed under dry environment situation. change in threshold voltage used as sensing metric to detect sensitivity mentioned device architecture biomolecule detection. Biomolecule position and their fill factor site have find out effect sensitivity....
Abstract Semiconductors have been used in solar energy conversion for decades based on the photovoltaic effect. An important challenge of photovoltaics is undesired heat generated within device. alternative approach thermionics, which uses thermal excitation electrons from an emitter to a collector across vacuum gap. If p-type semiconductor, photogeneration-induced quasi-Fermi level splitting can reduce effective barrier electron emission—a mechanism by photon enhanced thermionic emission...
With the digital revolution across world, including in low- and middle-income countries (LMICs) like Bangladesh, global burden of electronic waste (e-waste) is increasing. Consequently, environmental human health implications informal e-waste recycling practices LMICs are becoming a cause for concern. Here we report indoor dust air contamination from derived heavy metals shops Dhaka, capital Bangladesh. Representative Pb, Cu, Ni, Cr, Mn were measured samples collected three different located...
Two-dimensional layered material is touted as a replacement of current Si technology because its ultra-thin body and high mobility. Prominent transition metal dichalcogenides (TMD), Molybdenum disulphide (MoS2), channel for Field Effect Transistor has been used sensing nano-biomolecules. Tungsten diselenide (WSe2), widely logic applications, also shown better performance than other 2D materials in many cases. pH sensor integrated with Nanobiosensor most often since charges (value type)...
We investigate the performance of a micro gap vacuum thermionic energy converter considering loss mechanisms due to space charge effect and interelectrode radiative heat transfer. The dependencies near-field exchange on distance are derived based established theories. electrode temperatures determined by solving steady-state balance equations in numerical, iterative process constant flux input emitter. resultant behaviour different flow from electrodes is studied for wide range distances,...
The electronic and mechanical properties of 2-dimensional MoSi 2 N 4 change significantly due to the presence vacancy defects, which can lead novel applications in 2D electronics.
To determine the long-term outcomes for patients receiving polytetrafluoroethylene (PTFE)-covered stents as definitive therapy, in our institution, management of acute coronary perforation.Coronary perforation a complication percutaneous intervention (PCI) is associated with high morbidity and mortality. Management options included observation only or combination several all these approaches: reversal anticoagulation, prolonged balloon inflation, deployment standard stent, emergent cardiac...
In this work, a compact transport model has been developed for monolayer transition metal dichalcogenide (TMDC) channel MOSFET. The analytical solves the Poisson's equation inversion charge density to get electrostatic potential in channel. Current is then calculated by solving drift–diffusion equation. makes gradual approximation simplify solution procedure. appropriate of states obtained from first principle functional theory simulation considered keep physically accurate TMDC FET. outcome...
To address the challenge of growing global energy crisis and greenhouse effect, employing thermoradiative effect photodiodes to harvest radiative from colder outer space is considered a promising approach for direct nighttime renewable generation. By considering coupled atmosphere, ambient, non-radiative losses, thermodynamic model diodes (NTRDs) developed. The fundamental performance limit achievable electric power density device optimal designs NTRDs are theoretically investigated based on...
We present a solar thermionic energy converter (STEC) incorporating interelectrode spacer structures for harvesting. demonstrate the impact of loss on optimal performance and gap size STECs with without spacers. Under concentration factor 100, we show that maximum efficiency (5.3%) is significantly lower than (8.7%) at different gaps due to conducts heat parasitically. The ranges from few tenths micron microns spacers, while around 8μm Furthermore, device operation an internal support...
Background The rate of upgrading ductal carcinoma in situ (DCIS) to invasive cancer varies widely the literature with no consensus regarding sentinel lymph node biopsy (SLNB) for DCIS; however, some guidelines do recommend it event a mastectomy. primary aim this study was determine upgrade DCIS (IC) patients undergoing mastectomy and identify clinicopathological predicting factors upgrade. secondary SLNB positivity rate. Methodology We retrospectively analysed consecutive diagnosed through...
