A quat-silicone micro-emulsion (particle size <40 nm), an amino-silicone macro-emulsion (110 nm), and an alkyl modified silicone macro-emulsion (740 nm) were used to modify Scots pine (Pinus sylvestris L.) sapwood. Treated and uncoated boards were exposed to natural weathering for one year along with water treated controls according to EN 927-3. The treatment with silicone emulsions did not enh...

Reworking electronic packages is an integral process related to diagnostics and salvaging valuable materials. It is a meticulous and time-consuming procedure that requires some knowledge of the package material composition to determine compatible cleaning solutions and processes. Silicone adhesives are being used more frequently due to their ability to minimize shear stress during temperature c...

PURPOSE To present the finding of tiny silicone oil droplets in 15 eyes of 15 patients after intravitreal injections of an anti-vascular endothelial growth factor agent or triamcinolone acetonide and to discuss the likely source of silicone oil. METHODS In an observational case series, charts of patients who had undergone intravitreal injections by one surgeon were reviewed retrospectively. T...

Abstract The main component of Silicone-based heat transfer fluids is modified silicone oil. high and low using temperature silicone-based better than hydrocarbon organic fluids. raising the maximum means that it can obtain higher steam in process system, power generation efficiency turbine will be improved remarkably if are used parabolic through solar system. It also increase a thermal plant,...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

AbstractIntroduction Silicone gel breast implants are used for breast reconstruction post mastectomy. In the event of cancer recurrence, the radiation oncologists are forced to irradiate through the prosthesis device. Due to prosthesis higher atomic number dose perturbations occur during treatment. This study determined the influence of silicone gel thickness on the photon beam distribution. Ma...

Because of the increasing trend of body contour enhancements with injections, implants, and fillers, clinicians should be on high alert for the possibility of silicone-induced hypercalcemia as one of the differential diagnoses in a patient with history of silicone use. Hypercalcemia as a result of silicone injections has been reported, and there is concern that there will be more cases given th...

PURPOSE To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsiloxane), which is used with increasing frequency to treat complicated retinal detachments. METHODS CT was performed on a silicone oil/water phantom and on a patient with retinal detachments secondary to cytomegalovirus retinitis, treated by bilateral intraocular injections of silicone oil. CT appearan...

Purpose: The purpose of this study was to determine the influence of silicone remover on tensile bond strength of eight silicone-resilient denture liners to a denture base resin. Durability of bond strength of resilient denture liner to denture base resin was also examined by thermal cycling test. Materials and Methods: Eight commercial silicone resilient denture liners were used. The specimens...

BACKGROUND Combined with vitreoretinal surgery, silicone oil injection has become a standard technique and improves the prognosis of complex retinal detachment. As silicone oil leads to long term complications, removal of silicone oil from the eye is recommended. To evaluate the outcome after silicone oil removal, retinal redetachment, visual acuity, and complications were analysed. METHODS T...
