Polymer Gels: Fracture, Friction, Healing and Superabsorbency

Erk K.A., Purdue University, US

Polymer gels have many industrial uses, from drug-delivery and wound-healing materials to the superabsorbent gels used in baby diapers as well as high-performance concrete. The macro-scale physical properties of the polymer gels, including the gel’s [...]

Linseed oil miniemulsions stabilized by polyelectrolyte complex (gum arabic-chitosan)

Michel-Barba M.G., Espinosa-Andrews H., Centro de Investigación y Asistencia en Tecnología y Diseño del Estado de Jalisco, a.C., MX

An linseed oil miniemulsion was optimized using the microfludization process and finally stabilized by polyelectrolyte complexes formation. Emulsion preparation variables such as gum arabic/oil mass ratio (GA/O), oil volume fraction (), homogenization pressure and number [...]

Magnetic Nanofluids in Ultrasonic Testing

Sokolov V.V., Osipov M.I., Moscow State University of Instrument Engineering and Computer Science, RU

The use of the magnetic nanofluid as the bonding medium find an ever increasing application in ultrasonic non-destructive testing method. A thin layer of magnetic nanofluid which is adhered on the transducers face with a [...]

Transformative Design of Medical Oxygen Concentrator by Rapid Pressure Swing Adsorption

Vemula R.R., Kothare M.V., Sircar S., Lehigh University, US

The goal of this research work is design of a miniature medical oxygen concentrator (MOC) using a novel, single-bed rapid pressure swing adsorption (RPSA) process for personal use of chronic obstructive pulmonary disease (COPD) patients. [...]

Electrospun Functional Poly(ether amide) Composite Nanofibres

Jiang X., Liang S., Wang F., Geng W., Changzhou University, CN

Due to its unique physical and chemical properties, poly (ether amide) (Pebax) has been widely applied in membrane separation, chemical sensing, and medical applications. Pebax composite nanofibres offer advantages such as high contact area and [...]

The use of Ag5IO6 as an antimicrobial agent in wound dressing against microbial biofilms

Incani V., Omar A., Prosperi-Porta G., Nadworny P., Innovotech Inc, CA

This work explores the unique antibiofilm activity of pentasilver hexaoxoiodate (Ag5IO6). Impregnated wound dressings with Ag5IO6 were designed and their antibiofilm activity was compared with various commercially available silver and non silver-containing dressings. Ag5IO6-wound dressings [...]

Design of a novel melatonin Pickering emulsion sunscreen

Ribeiro H., Faculdade de Farmácia cda Universidade de Lisboa, PT

Melatonin, the main secretory product of the pineal gland, was recently found to have a protection effect against photocarcinogenesis based on its free radical scavenger and antioxidant activity. On the other hand, the daily use [...]

Dex40-GTMAC3, modified dextran as a novel heparin antagonist

Kalaska B., Kaminski K., Sokolowska E., Czaplicki D., Kujdowicz M., Stalinska K., Szczubialka K., Bereta J., Pawlak D., Nowakowska M., Mogielnicki A., Medical University of Bialystok, PL

Protamine is the only registered antidote preventing bleeding of patients treated with unfractionated heparin (UFH). However protamine may induce anaphylactic shock or serious hypotension. We aimed to develop an alternative fully synthetic UFH antidote as [...]

Nonclinical evaluation of heparin binding copolymer – HBC1 for restoring of blood coagulation after heparin treatment

Kalaska B., Sokolowska E., Kaminski K., Miklosz J., Shin-ichi Y., Błazejczyk A., Wietrzyk J., Kasacka I., Szczubialka K., Pawlak D., Nowakowska M., Mogielnicki A., Medical University of Bialystok, PL

The incredible progress and wide use of various medical devices during intravascular or cardiac interventions increased the need for administration of anticoagulants, such as heparins. Protamine sulfate – a protein isolated from salmons is the [...]

Electrophoretic Coating of Hydroxyapatite-Boron Nitride Nanocomposites on Titanium Implants

Bakan F., Sezen M., Goncu Y., Ay N., Sabanci University, TR

Titanium (Ti) and its alloys have long been used as implant materials in dental and orthopedic applications. However, they can suffer certain disadvantages, such as poor osteoinductive properties and low corrosive-wear resistance. The potential of [...]
