The influences of alcohol adding and three different gas spargers (single orifice, perforated plate, and sinter plate) on the gas holdup in an external-loop airlift reactor were studied. The experimental results show that the gas holdup can be increased by ...
Using laboratory X-ray photoelectron emission microscopy (XPEEM), we investigated the doping efficiency and thermal stability of iodine on as-grown graphene on Pt. After iodine adsorption of graphene in saturated vapor of I-2, monolayer and bilayer graphen ...
The effect of inorganic semivolatile aerosol compounds on the cloud condensation nucleus (CCN) activity of aerosol particles was studied by using a computational model for a DMT-CCN counter, a cloud parcel model for condensation kinetics and experiments to ...
Hybrid organometallic halide perovskites have been intensively investigated in the past few years, especially the CH3NH3PbI3, as highly efficient light harvesters for various optoelectronic application both for sensing and emitting light. However, despite ...
The adsorption of water on etched (001) surfaces of L-, D- and DL-valine crystals has been characterized by atomic force microscopy (AFM) using different operational modes (contact, non-contact and electrostatic) above and below the dew point, the temperat ...
Recent investigations on friction welded wood-to-wood connections have shown interesting capacities of these adhesive free joints for further development towards constructional elements. This paper addresses challenges and technical requirements for the en ...
The water vapor profile derived from Raman lidar measurements is obtained by taking the ratio of water vapor and nitrogen Raman-shifted signals. The proportionality factor that converts the signal ratio to water vapor/air mixing ratio is referred to as lid ...
Raman lidars exploit the proportionality between the intensity of scattered by a Raman process laser radiation and the number density of the scattering molecules to derive water vapor mixing ratio profile. Water vapor/air mixing ratio is directly proportio ...
Lithium cations are shown to have a significant role on catalyzing oxygen and proton reduction along with SN1 reactions in biphasic systems. We propose that this catalytic effect is due to the surprising acidity of the hydrated cations; interactions betwee ...
Aerosol-cloud interactions are affected by the rate at which water vapor condenses onto particles during cloud droplet growth. Changes in droplet growth rates can impact cloud droplet number and size distribution. The current study investigated droplet gro ...
