Zastosowanie ultrafiltracji do dezynfekcji i doczyszczania ścieków oczyszczonych = Ultrafiltration process in disinfection and advanced treatment of tertiary treated wastewater
PublikacjaW pracy przedstawiono wyniki badań nad ultrafiltracją komunalnych ścieków oczyszczonych. Ustalono, że ultrafiltracja jest skuteczną metodą dezynfekcji. W permeacie obserwowano jedynie pojedyncze komórki bakterii wskaźnikowych. Proces ultrafiltracji umożliwia dalszą poprawę parametrów fizyczno-chemicznych ścieków oczyszczonych. Najlepiej usuwane były mętność oraz fosfor ogólny, dobre efekty uzyskano w usuwaniu ChZT oraz BZT5, w...

Recent advances in electrochemically surface treated titanium and its alloys for biomedical applications: A review of anodic and plasma electrolytic oxidation methods
PublikacjaNowadays, titanium and its alloys are widely used materials in implantology. Nevertheless, the greatest challenge is still its appropriate surface treatment in order to induce optimal properties, which facilitates formation of a permanent bond between the implant and human tissue. The use of electrochemical treatment such as anodic oxidation or plasma electrolytic oxidation allows for the production of porous coating that mimics...

Role of nitrogen in optical and electrical band gaps of hydrogenated/hydrogen free carbon nitride film
PublikacjaWe report the optical and electrical band gap energy of amorphous hydrogenated carbon nitride (a-HCNx) and carbon nitride (a-CNx) as a function of nitrogen concentration (N/C). The optical band gap of a-HCNx and a-CNx films has been determined by means of Ellipsometry and UV-VIS. Both optical and electrical band gaps increase with elevated nitrogen concentration. Experimentally obtained electrical band gap is compared with the...

Optimization of the Relative Humidity of Reactant Gases in Hydrogen Fuel Cells Using Dynamic Impedance Measurements
PublikacjaWater management is a key factor affecting the efficiency of proton exchange membrane fuel cells (PEMFCs). The currently used monitoring methods of PEMFCs provide limited information about which processes or components that humidity has a significant impact upon. Herein, we propose the use of a novel approach of impedance measurements using a multi-sinusoidal perturbation signal, which enables impedance measurements under dynamic...
