Supercritical and ultrasound-assisted extracts fromPleurotus pulmonariusmushroom: chemical profiles, antioxidative, and enzyme-inhibitory properties
(Wiley, Hoboken, 2021)
Background This study provides an insight into the impact of ultrasound-assisted extraction with water as solvent (UAEW) and extraction by supercritical carbon dioxide (SC-CO2) with 5% EtOH on antioxidant and enzyme ...
Underpotential deposition of lead on Pt(111) in the presence of bromide: RRDPt(111)E and X-ray scattering studies
(Elsevier Science Sa, Lausanne, 1998)
The underpotential deposition (upd) of Pb onto Pt(lll) in solution containing Br- was examined by classical RRDP(111)E electrochemical methods in combination with in situ surface X-ray scattering measurements. The results ...
Electrooxidation of H-2, CO, and H-2/CO mixtures on a well-characterized Pt70Mo30 bulk alloy electrode
(Amer Chemical Soc, Washington, 1998)
The electrochemical oxidation of hydrogen (H-2), carbon monoxide (CO), and their mixtures (500 ppm-2%) on a well-characterized Pt70Mo30 bulk alloy was examined using the rotating disk electrode technique in 0.5 M H2SO4 at ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - II. A continuous flow adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A continuous mode of operation is considered, ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - I. A semi-batch adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A semi-batch mode of operation is considered, ...
Nonlinear frequency response of adsorption systems: isothermal batch and continuous flow adsorbers
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The problem of nonlinear frequency response of adsorption systems is treated using the concept of higher-order frequency response functions (FRFs). The FRFs on the adsorber and on the particle scale are considered. Based ...
