Inorganic metal-halide cubic perovskite semiconductors have become more popular in industrial applications of photovoltaic and optoelectronic devices. Among various perovskites, lead-free materials are currently most explored due to their non-toxic effect on the environment. In this study, structural, electronic, optical, mechanical properties FrBX3 (B = Ge, Sn; X Cl, Br, I) investigated through first-principles density-functional theory (DFT) calculations. These found exhibit semiconducting...
In this study, a series of nanocrystalline Ni0.7Cu0.30AlxFe2-xO4 (x = 0.00 to 0.10 with step 0.02) has been synthesized through the sol–gel auto combustion technique. The structural, morphological, dielectric, and electrical properties nanoparticles are analyzed due substitution effect Al3+ content. structural study performed XRD FTIR analyses. extracted patterns assure single-phase cubic spinel structure all samples in high crystalline nature maintaining their homogeneity. average...
Abstract Recently, the fabrication of a scaffold from biomaterials has been increased due to lack adequate natural bone for grafting. In this study, hydroxyapatite-chitosan-alginate-polyamide (HCAP) synthetic was fabricated using thermally induced phase separation (TIPS) technique. The cross-linked with either chemical cross-linker (calcium chloride, 2-hydroxyethyl methacrylate (HEMA), or glutaraldehyde (GTA)) physical (gamma irradiation (IR)) resulting in scaffolds HCAP-CaCl 2 , HCAP-HEMA,...
Burn has terrible consequences for the affected patients, making them vulnerable to wound infections and septicemia, which results in physical mental disability death, necessitating superior treatment options. Human amniotic membrane (HAM) been utilized burn wounds decades its low immunogenicity, angiogenic, anti‐inflammatory, antimicrobial properties promoting epithelialization. Silver nanoparticles (AgNPs), on other hand, have promote fibroblast migration. This study aimed determine...
Nanocrystalline samples of Ni0.7−xCuxCd0.3Fe2O4 (x = 0.0–0.5, with step 0.1) have been synthesized via auto-combusted sol-gel method. In this study, we present the structural and electric properties Cu substituted Ni-Cd ferrite nanoparticles at room temperature varying frequencies from 20 Hz to 15 MHz. X-ray diffraction (XRD) patterns confirm single-phase cubic spinel structure without impurity. The crystallite size is found in nano-scale range (17–27 nm) lattice parameter increase linearly...
Having inadequate health care systems and poor socio-economic infrastructure, Bangladesh has been braving to contain the impact of current COVID-19 pandemic since March, 2020. To curb diffusion COVID-19, local government responded outbreak by enforcing a set restricted measures on economic social activities across country.Here, we aim assess propagation estimating coronavirus active cases mortality rate in two major business hubs Bangladesh, namely Dhaka Chittagong city under flexible...
Nanoparticles of Cu0.65Zn0.35AlxFe2-xO4 (x = 0.00 to 0.10, in the step size 0.025) were synthesized by employing auto-combusted sol–gel process and annealed at 700 ˚C. The effect Al3+ substituted Cu-Zn mixed nanoferrites on structural, magnetic, dielectric, electrical properties has been investigated. behavior structural exploration these compositions implemented X-ray diffraction technique further refined through Rietveld refinement which provides homogeneity parameters like crystal...
Bangladesh has been combating the COVID-19 pandemic with limited financial resources and poor health infrastructure since March, 2020. Although government imposed several restricted measures to curb progression of outbreak, these arrays are not sustainable in long run. In this paper, we use a data-driven forecasting model considering susceptible, exposed, infected, recovered deaths status through time assess impact lift flexible lockdown on dynamics Bangladesh. Our analysis demonstrates that...
Background: The National Institutes of Health Stroke Scale or NIH (NIHSS) is a widely used tool for assessing stroke severity. We conducted this study to determine the severity patients admitted in tertiary care hospital.Methods: This cross sectional Department Neurology, Dhaka Medical College Hospital from April 2016 October involving 91 acute patients.Result: About half (44%) were older than 60 years age and mean was 60.34(±16.1) at onset there slight female predominance (51.6%). Majority...
In this study, the absorber layer of Cadmium Telluride (CdTe) ultra-thin solar cell was analyzed by using one dimensional simulator Analysis Microelectronic and Photonic Structures (AMPS 1D) software. A novel structure CdS:O/CdTe is suggested in research that emphases on conversion efficiency.

Abstract Background Post-kala-azar dermal leishmaniasis (PKDL) is a dermatosis that occurs 2–3 years after an apparently successful treatment of visceral (VL). In rare cases, PKDL concurrently with VL and characterized by fever, splenomegaly, hepatomegaly or lymphadenopathy, poor nutritional status known as Para-kala-azar (Para-KDL). Co-association active in patients documented Africa, but very few case reports are found South Asia. Case summary We present Dermal Leishmaniasis (Para-KDL)...
