The authors introduced waste plastic pyrolysis oil (WPPO) as an alternative fuel characterized in detail and compared with conventional diesel. High density polyethylene, HDPE, was pyrolyzed a self-designed stainless steel laboratory reactor to produce useful products. HDPE completely at 330–490°C for 2-3 hours obtain solid residue, liquid oil, flammable gaseous hydrocarbon Comparison of the properties petrodiesel standards ASTM D 975 EN 590 revealed that synthetic product within all...
Cancer is the most frequent life-threatening disease which has highest mortality rate throughout world. Diagnosis of cancer at early stage can plays a critical role for its effective and successful treatment. Traditional diagnostic methods screening are costly, time-consuming, not practical repeated screenings. However, biomarker-based diagnosis emerging as one promising strategies diagnosis, monitoring progression, subsequent This review describes recent advances improvements in...
The concentrations of major (Si, Al, Ca, Fe, and K) minor (Cd, Mn, Ni, Pb, U, Zn, Co, Cr, As, Cu, Rb, Sr, Zr,) elements in the surficial sediments were studied an attempt to establish their concentration Bengal coast. It was revealed that majority trace have been introduced into marine from riverine inflows are also affected by impact industrial, ship breaking yard, gas production plant, urban wastes. heavy metals measured using Atomic Absorption Spectroscopy Energy Dispersive X-ray...
In this study, we measured the distribution of heavy metals (Pb, Ni, Fe, Mn, Cd, Cu) in surface water Bengal Coast at southern part Bangladesh. We also examined common quality parameters to discuss impacts pollution. It was revealed that majority have been introduced into marine from riverine inflows are affected by impact industrial, ship breaking yard, gas production plant and urban wastes. The concentration using atomic absorption spectroscopy (AAS) instrument. Heavy concentrations were...
Global warming is considered as a consequence of extensive use fossil fuels. Post combustion CO2 capture an interesting and alternative solution where mixed matrix membranes (MMMs) can be exciting candidate. This research focuses on the optimization MMM composition consisting Pebax® 3533 polymer porous coordination (PCP) MIL-178(Fe) filler for gas separation application. characterized with SEM, TEM TGA were applied to compare bare MMM. Optimum obtained was 5 wt.% in 3533. Average thickness...
Purpose The purpose of this study is to understand the inhibitor behavior specific drug against mild steel corrosion and their adsorption mechanism on surface. Design/methodology/approach Corrosion rates are influenced by formation aggregates at Detail surface characterizations have been studied before after drugs in 1N HCl solution. Scanning electron microscopy, atomic force microscopy Fourier transform infrared spectroscopy were used examine effect Findings analysis suggested that metal...
Mixed matrix membranes (MMMs) consisting of fillers (e.g. metal organic frameworks (MOFs)) in polymer are considered as an interesting alternative for capturing post combustion CO2 towards a sustainable development. This research is focused on the recycling MMMs made Pebax® 1657 and MOF ZIF-94. Upon MMM preparation, characterization testing, were dissolved to recover MOFs separately. Recovered products characterized by SEM, EDX, FTIR, TGA, XRD, DLS, mass spectrometry N2 adsorption compare...
With development of nanotechnology, the biological synthesis process deals with synthesis, characterization, and manipulation materials further at nanoscale which is most cost-effective eco-friendly rapid as compared to physical chemical process. In this research silver nanoparticles (AgNPs) were synthesized from nitrate (AgNO 3 ) aqueous solution through plant leaf broth Ocimum sanctum reactant well capping agent stabilizer. The formation AgNPs was monitored by ultraviolet-visible...
Abstract Global energy demand is met in large part, by burning of fossil fuels, which causing global warming. Mixed matrix membranes (MMMs) with metal organic frameworks (MOFs) as fillers are an interesting alternative for capturing post combustion CO 2 would make the sector sustainable. This research focused on synthesis MOF ZIF‐94 from recycling its mother liquors and incorporation synthesized into a Pebax MH 1657 MMM fabrication. The pH temperature modified monitored this results various...
A novel and water stable Fe( iii ) based porous coordination polymer was discovered. Due to its interesting features for CO 2 capture, this material used as an inorganic filler the processing of composite membranes in /N separation.
Edible oils and fats are recognized as vital constituents of our daily diet contribute significantly to the regulation different body functions. oil quality is largely determined by physicochemical characteristics sensory evaluation due its nature processing procedure. The present study includes parameters soybean, palm, mustard bran at room temperature after heating 180oC for 10 mins using analytical methodologies. These properties were studied evaluate compositional also investigate effect...
This paper investigated a novel loop-heat-pipe based solar thermal heat-pump system for small scale hot water production household purposes. The effective use of energy is hindered by the intermittent nature its availability, limiting and effectiveness in domestic industrial applications especially heating. easiest most used method conversion into energy. We developed prototype heating experimental test. reported investigation efficiency different seasons which 29.24% summer, 14.75% winter,...
Background and Objective: Groundwater is one of the most important renewable resources which play a great role into livelihood, economies agriculture sector in nation.However, this valuable resource has been defected through various ways.This study aimed to investigate effect over exploitation groundwater on Barind Tract area its probable impact environment.The fluctuation due deep tubewells installed for irrigation also investigated.The was Chapai Nawabganj district located North-western...
