Before light irradiation, the dissolved air was thoroughly removed by a vacuum pump. The system was irradiated from the top using a 300 W xenon lamp (Perfectlight PLS-SXE300D). The temperature of the reaction solution was maintained at 10 °C by circulation of cool water. Because these...
for the different samples. Photoluminescence (PL) and Raman mapping of the flakes was conducted to further depict the mono- and multi-layer regions using a 532 nm pump laser with 8–80 μW power and a spot size of∼0.5 μm (Horiba Scientific LabRAM HR 800). Metal source/...

Accurate assessment of undrained shear strength (USS) for soft sensitive clays is a great concern in geotechnical engineering practice. This study applies novel data-driven extreme gradient boosting (XGBoost) and random forest (RF) ensemble learning methods for capturing the relationships between the US...
To measure pressure in the evaporator, the adsorbent bed and the methanol storage tank, 4 vacuum barometers (1 to zero bar) are used. To create a vacuum in a required vacuum, a vacuum pump (JB model) is used. A radiation intensity (JB model) is used to measure the intensity of ...
Gas Cylinder Fueling Station Liquid Argon Cryogenic Filling Pump $1,880.00 - $4,580.00 Min. order: 1 set Yds-20 Small Capacity Liquid Nitrogen Semen Tank Liquid Nitrogen Bottle $240.00 - $250.00 Min. order: 1 set 210L 2.88MPa Cryogenic Stainless Steel Dewar Bottle For Liquid Co2 O2 N2 Arg...
However, 44 MW of heat is required for the desorption of CO2 for the base case. Therefore, 16 MW of heat has to be integrated with lower temperature heat sources (e.g the cooler and condenser duties) using heat pump technology. Because heat pumps consume electricity, it is clear that by...
An ever-increasing demand for electrical power and soaring levels of energy consumption around the world have led to an energy crisis. Thus, this paper aims to review the conventional technologies against those of newer developments in electrical power generation such as using nitrogen generators. The...
such as a solar pump in an agricultural area without an irrigation system [12]. However, those solar energy usage applications are mainly utilized for loads that consume electrical energy. If solar energy is preferred for other applications, which do not consume electrical energy as a primary sou...
