Phase transitions of nanoemulsions using ultrasound: Experimental observations
(Elsevier, 2012)The ultrasound-induced transformation of perfluorocarbon liquids to gases is of interest in the area of drug and gene delivery. In this study, three independent parameters (temperature, size, and perfluorocarbon species) ... -
Phase transitions of perfluorocarbon nanoemulsion induced with ultrasound: A mathematical model
(Elsevier, 2013)While ultrasound has been used in many medical and industrial applications, only recently has research been done on phase transformations induced by ultrasound. This paper presents a numerical model and the predicted results ... -
Phased Array Technique for Brain Source Localization
(2012-01)Magnetoencephalography (MEG) and Electroencephalography (EEG) are two popular non-invasive techniques that directly measure the magnetic/electric signals generated from the brain's electrical activity, unlike functional ... -

Phosphorus and Algae Removal via Adsorption
(2012-01)Algal bloom, commonly known as Red Tide in coastal areas, has become one of the major problems facing desalination plants due to the high biomass concentration of microalgae associated with it. It causes operational problems ... -
Phosphorus Recovery from the Wastewater Stream - Necessity and Possibilities
(Taylor & Francis, 2016)The annual demand of phosphorus (P) for fertilizer use is more than 550,000 t in Germany. Several of the input streams like mineral fertilizer produced from phosphate rock or sewage sludge are problematic due to contamination ... -
Photo-Induced Drug Release from Polymeric Micelles and Liposomes: Phototriggering Mechanisms in Drug-Delivery Systems
(MDPI, 2022)Chemotherapeutic drugs are highly effective in treating cancer. However, the side effects associated with this treatment lower the quality of life of cancer patients. Smart nanocarriers are able to encapsulate these drugs ... -
The Photocatalytic Degradation of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin in the Presence of Silver–Titanium Based Catalysts
(MDPI, 2020)Polychlorinated dibenzo-p-dioxins (PCDD) are persistent toxic compounds that are ubiquitous in the environment. The photodegradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the presence of silver titanium oxide ... -
Photocatalytic demulsification of oil/water emulsions containing nonionic surfactant
(Springer, 2020-11)Separation of oil-water (OW) emulsions is investigated using a photocatalytic demulsification approach. Experiments were conducted using two types of photocatalysts, namely, ZnO and TiO2. The emulsion samples were prepared ... -
Photocatalytic UV degradation of 2,3,7,8-tetrachlorodibenzofuran in the presence of silver zeolite
(Springer, 2017-02-24)Silver clusters were introduced into the framework of zeolite Y. Low-temperature solid-state luminescence indicates the formation of silver–silver excimers and exciplexes that were found to be activated at 250 and 300 nm, ... -
