● TABLE II Thin Layer ... Abstract TOP The cause of silicone gel implant aging and rupture is not known. Recent reports indicate the failure rate is higher than previously published, and implant aging and rupture may be due to progressive mechanical deterioration of the outer vulcanized silicone shell. It is known that lipids are absorbed by the hydrophobic silicone elastomer, and lipid infiltr...

This project’s goal was to mimic the Saharan silver ant’s micro-hair arrays by creating a solar heat reflecting membrane with parallel-aligned Al-ZnO microrods using Mayer rod coating method. The synthesis of carried out hydrothermal then produced mixing liquid silicone rubber and spreading mixture into shape rod. dragging microrod, confined between polypropylene film, induces partial alignment...

AIM Silicone oil is a useful tamponading material used in complex vitroretinal surgery. However, the use of silicone oil is associated with emulsification which can lead to vision threatening complications. The authors developed an experimental model to study the effect of encircling band on silicone oil emulsification. METHODS Two identical artificial eye chambers were constructed with circu...

A Sporothrix variecibatus-inoculated biotrickling filter (BTF) was examined for styrene removal, without and with the addition of silicone oil, at different empty bed residence times. The highest elimination capacities (ECs) were 172.8 (without silicone oil) and 670 g m(-3)h(-1) (with silicone oil), respectively, corresponding to a 4-fold improvement in presence of oil. The addition of silicone...

This in vitro study evaluated the antibacterial effect of copper additives in silicone implants. Specimens of a standard silicone material used in breast augmentation and modified copper-loaded silicone specimens were prepared and incubated in a Staphylococcus epidermidis suspension (2 h, 37 degrees C). After the quantification of adhering staphylococci using a biofluorescence assay (Resazurin)...

Three commercial silicone emulsions with different functional groups i.e., quat-silicone micro-emulsion (<40 nm particle size), amino-silicone macro-emulsion (110 nm), and silicone macro-emulsion with alkylmodified side groups (740 nm) were used to protect wood samples against fungal decay. The addition of the emulsions to an agar growth medium revealed that all three silicone formulations inhi...

New polysiloxane oligomers containing phosphorus, 6-(2-(dihydroxy(methyl)silyl)ethyl)dibenzo[c,e][1,2]oxaphosphinine 6-oxide (DOPO-VMDMS), have been synthetized and grafted to the remaining hydroxyl groups of alkyd resins in order obtain hybrid with flame retardant properties. These silicone demonstrated better drying time, gloss chemical resistance than reference without DOPO-VMDMS. Moreover, ...

Abstract Herein we studied the efficiency of a protective transparent and reversible nano silicone wax coatings (NSW) to protect bronze artifacts extracted from Herakleon City, Abu Kir Bay, Alexandria, Egypt. The structured film resulted in formation structure that can act as barrier layer corrosion. application NSW on was evaluated by electrochemical impedance spectroscopy scanning electron mi...
