Hydrogen production by the steam reforming of synthetic biogas in atmospheric-pressure microwave (915 MHz) plasma

open access: yesScientific Reports, 2023
This paper is a contribution to the development of microwave plasma-based technology aimed at efficient hydrogen (H2) production from a so-called synthetic biogas, considered a mixture of methane (CH4) and carbon dioxide (CO2), which can contain up to 70%

Inviscid mean flow through and around groups of bodies [PDF]

open access: yes, 2004
General estimates are derived for mean velocities through and around groups or arrays of fixed and moving bodies, in unbounded and bounded domains, which lie within a defined perimeter.

SHOCK WAVE INDUCED FLOW SEPARATION CONTROL BY AIR-JET AND ROD VORTEX GENERATORS

open access: yesTASK Quarterly, 2015
Flow separation control by Vortex Generators (VGs) has been analyzed over the last decades. The majority of the research concerning this technology has been focused on subsonic flows where its effectiveness for separation reduction has been proven. Less

Granular Flows in Fluid

open access: yes, 2012
Underwater avalanches are a major risk to offshore structures. The mechanisms involved in the initiation and propagation of underwater granular avalanches are complex. They depend mainly on the slope angle, density, and quantity of material destabilised.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Two-phase flow experimental studies in micro-models [PDF]

open access: yes, 2013
The aim of this research project was to put more physics into theories of two-phase flow. The significance of including interfacial area as a separate variable in two-phase flow and transport models was investigated.

Hydrogen fuel production from CO2/CH4 mixture using a novel type of an atmospheric pressure microwave (2.45 GHz) plasma source

open access: yesScientific Reports
We report the use of microwave plasma for the production of hydrogen-enriched gas by converting a mixture of CO₂ and CH₄. A novel type of compact and simple in design, waveguide-based, atmospheric pressure plasma source is used.

Mechanics of a plant in fluid flow [PDF]

open access: yesJournal of Experimental Botany, 2019
AbstractPlants live in constantly moving fluid, whether air or water. In response to the loads associated with fluid motion, plants bend and twist, often with great amplitude. These large deformations are not found in traditional engineering application and thus necessitate new specialized scientific developments.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
