Utilization of Waste Heat Emitted by the Kiln

International Journal of Innovative Science and Research Technology (IJISRT)
Kiln is where dolomite, iron ore and coal are used as intake product for the formation of sponge iron. At high temperature raw materials are molded to get the desired product. Due to this high temperature lots of heat is emitted from the kiln. The temperature in the kiln is about 800-1100°c, and it emits heat, this emitted heat storage is the cause for

Biomimetic Core–Shell Liposome Nanoparticles Deplete Lipoproteins and Enhance the Purity of Extracellular Vesicles from Human Blood

Advanced Functional Materials, EarlyView.
Lipoprotein‐mimicking nanoparticles (SL‐NPs), comprising Fe3O4@SiO2 cores coated with liposomal bilayers, selectively capture lipoproteins through protein corona formation. The resulting SL‐NP‐lipoprotein complexes can be removed by low‐speed centrifugation, thereby enhancing the purity of small extracellular vesicles (sEVs) isolated from human serum ...

APPLICATION OF HEAT PUMPS FOR UTILIZATION OF WASTE HEAT IN INDUSTRY

, 2022
U energetski intenzivnim industrijama kao što su livnice, čeličane, fabrike hemijske industrije, rafinerije i dr. značajne količine otpadne toplote se generišu u obliku rashladne vode čija temperatura je uobičajeno u opsegu od 25 do 40°C. U slučajevima kada se otpadni fluidni tokovi niske temperature ne mogu primeniti direktno u procesu, postoji ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)
