Influence of the Sparger Type and Added Alcohol on the Gas Holdup of an External-Loop Airlift Reactor

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 ...

Doping characteristics of iodine on as-grown chemical vapor deposited graphene on Pt

Olivier Renault, Hokwon Kim, Nicolas Chevalier

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 ...

Water adsorption on etched hydrophobic surfaces of L-, D- and DL-valine crystals

Juan José Segura Sugranes

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 ...

Instrumental correction of the uneven PMT aging effect on the calibration constant of a water vapor Raman lidar

Bertrand Calpini, Valentin Simeonov, Salomon Fastig

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 ...

Absolutely calibrated Raman lidar as a reference tool in atmospheric humidity profiling

Valentin Simeonov

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 ...

Surprising acidity of hydrated lithium cations in organic solvents

Hubert Girault, Liang Qiao, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

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 ...

Suppression in droplet growth kinetics by the addition of organics to sulfate particles

Athanasios Nenes

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 ...
