Phase transitions in metal halide perovskites triggered by external provocations produce significantly different material properties, providing a prodigious opportunity for comprehensive applications. In the present study, first principles calculation has been performed with help of density functional theory using Cambridge Serial Total Energy Package code to investigate physical properties lead-free CsSnBr3 halides under various hydrostatic pressures. The effect pressure is determined range...
Flexible, transparent, and biodegradable films that can shield dangerous UV high-energy blue light (HEBL) are high in demand to satisfy the ever-increasing expectations for environmental sustainability. To achieve this goal, biopolymer alginate is an excellent choice has outstanding film-forming ability. However, limitation of poor HEBL blocking Thus, study, blocker graphitic carbon nitride (g-C3N4) was incorporated enhance compatibility, applicability, durability. The ATR-FTIR, TGA, DTG,...

Xylocarpus mekongensis Pierre is the important tree species of Sundarbans. The present study was conducted to evaluate effect salinity on survival and growth X. seedlings. distributional patterns nitrogen, phosphorus, potassium, sodium, carbon in seedling parts were also examined relation salinity. Comparatively higher (95%) seedlings observed at non-saline slightly saline conditions (0-5 PSU) it decreased 78% 35 PSU relative rate (RGR) (0 5 compared Nutrients, concentration are found vary...
This study attempts to investigate the change in operating performance of firms as they go from private public ownership. Using data all non-financial firms, which floated initial offerings (IPOs) 2008 2015, this finds that there is a significant decline measured by ROA, asset turnover, ROS, and OCFTA after IPO continues for next two three years with highest deterioration being observed immediate year IPO. Moreover, when uses age, debt ratio, sales, capital expenditure, event explain...
Structural, electronic, optical, and mechanical properties of cubic SnZrO3 SnHfO3 have been studied under different hydrostatic pressures within the framework density functional theory. A strong atomic interaction resulting from a considerable drop in lattice parameter bond length was observed. The Sn–O Hf/Zr–O showed ionic weak covalent characteristics, respectively, strengths are found to enhance applied pressure. Poisson’s ratio these compounds also supports bonding nature. external...
Abstract. To estimate the annual recreational value provided by Foy’s Lake, using most applicable model for on-site data, is main objective of this study. adhere to study, individual travel cost method (ITCM) has been applied and zero truncated poisson regression found plausible among other models consumer surplus. Based on estimate, surplus or benefits per trip visitor can be recommended as BDT 5,875 US $ 73.44 counting visitor, (total surplus) lake 321 million 40.2 million. Keywords:...
Actively managed funds try to outperform by deviating from passive benchmarks such as the S&P 500, leading imperfect diversification and higher idiosyncratic volatility. The volatility imposes an additional cost shareholders. In this study, using data of all closed-end mutual listed with Dhaka Stock Exchange (DSE) 2012 2019, I have attempted quantify expense on portfolio then estimate true ratio net alpha actively a new measure for diversification. study finds that mean is 1.42%...
Phase transitions in metal halide perovskites triggered by external provocations produce significantly different material properties, providing a prodigious opportunity for comprehensive applications. In the present study, first principles calculation has been performed with help of density functional theory (DFT) using CASTEP code to investigate physical properties lead-free CsSnBr3 under various hydrostatic pressures. The pressure effect is determined range 0-16 GPa. Subsequently,...
