The Effect of Nanobubbles on Transdermal Applications.

In the present work, a new method for dermal delivery using nanobubbles (NBs) is investigated. Oxygen NBs are generated in deionized water and used to produce cosmetic formulations with hyaluronic acid as an active ingredient. Nanobubbles result in the improvement of the effect and penetration of the active ingredient through Strat-M, a synthetic membrane that resembles human skin.

A novel device for in situ study of gas adsorption under rotation.

The effect of rotation on adsorption kinetics of CO on activated carbon (AC) is studied using a novel rotation device. The device consists of a rotating cylindrical cell with inner dimensions of 4.5 cm radius and 1 mm height, while it operates at 5000 and 8000 rpm.

A rotating sample cell for measurements of adsorption with x-rays.

A sample cell which facilitates adsorption in conjunction with small angle x-ray scattering under a rotational field is presented. The device allows dynamic phenomena that take place within a pore system to be investigated by x-rays. As an example, a sample of Vycor porous glass was measured at relative pressures p/p = 0 and p/p = 0.
