Optimizing the use of ultrasound to deliver chemotherapeutic agents to cancer cells from polymeric micelles
(Elsevier, 2011)In this study, we present an artificial neural network (ANN) model that attempts to predict the dynamic release of doxorubicin (Dox) from P105 micelles under different ultrasonic power densities at 20 kHz. The goal is to ... -
Optimum ethane recovery in conventional turboexpander process
(Elsevier, 2010)Ethane recovery in a conventional turboexpander process is optimized considering different demethanizer pressures and different feeds: a lean gas and a rich one. The design variables are varied, while meeting process ... -
Over-Pressure Suppresses Ultrasonic-Induced Drug Uptake
(Elseviser, 2008)Ultrasound (US) is used to enhance and target delivery of drugs and genes to cancer tissues. The present study further examines the role of acoustic cavitation in US-induced permeabilization of cell membranes and subsequent ... -
Parametric Study of a Single Effect Lithium Bromide-Water Absorption Chiller Powered by a Renewable Heat Source
(SDEWES, 2020)This work investigates the performance of a single-effect absorption chiller utilizing an aqueous lithium bromide solution as the working fluid and driven by hot fluid rejected from either a geothermal power plant or the ... -
Performance of BFRP RC beams using high strength concrete
(Elsevier, 2021)This research investigates the flexural behavior and serviceability performance of basalt fiber-reinforced polymer (BFRP) reinforced concrete (RC) beams cast with normal- and high-strength concretes (NSC and HSC). Carbon ... -
Performance of CI Engine Operating with Hydrogen Supplement Cocombustion with Jojoba Methyl Ester
(Elsevier, 2016-06-29)The present work experimentally investigates the performance of compression ignition (CI) engine which operates on hydrogen and Jojoba methyl ester (JME). The hydrogen is introduced by enriching air-intake manifold with ... -
pH and ultrasound dual-responsive drug delivery system based on PEG–folate-functionalized Iron-based metal–organic framework for targeted doxorubicin delivery
(Elsevier, 2021)In recent years, the use of metal–organic frameworks (MOFs) as drug nanocarriers has gained attention because of their extraordinary physical and chemical properties. In this work, dual-responsive iron-based MOFs were ... -
pH-Responsive Nanocarriers in Cancer Therapy
(MDPI, 2022)A number of promising nano-sized particles (nanoparticles) have been developed to conquer the limitations of conventional chemotherapy. One of the most promising methods is stimuli-responsive nanoparticles because they ... -
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 ... -
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 ... -
Photocatalytic demulsification of oil/water emulsions containing nonionic surfactant
