“…The unique properties of polysiloxanes are due to the presence of both polar inorganic backbone and organic nonpolar functional groups, and as reported in many literature references [5,6,7,8], this hybrid nature is reflected in a close relationship between the structure of the polymer molecule and its physicochemical properties. The five principal structures of polysiloxanes are linear, cyclic ring polymer, branched, crosslinked, and crosslinked easily transformed into a three-dimensional network [3].…”

One of the historical problems of medicine is that often, diagnosis and therapy do not interface, at best. Moreover, especially in some areas, such as oncology, the stress for the organism during the two phases (diagnosis and therapy) can become excessive, and be fatal to the success of the treatment. The extraordinary progress of nanotechnology in the last 25 years has offered the opportunity to build a nanoplatform able to ferry drugs, and loads onto them both imaging and therapeutic functions, thus creating nanosystems capable of diagnosis, drug delivery, and monitoring of therapeutic response. The purpose of this unusual, and up to recent times, unimaginable, marriage between diagnosis and therapeutics is the reaching of protocols more specific to individuals. The dual use of particles/device lead to a personalized medicine. Due to their biocompatibility, versatility, physical and chemical resistance, and ability to be functionalized, silica nanoparticles and polysiloxanes are the heart and the shield of this nanoplatform, respectively. In this short review, I analyze the applications of these silicon-based materials in the field of controlled drug delivery.

“…Normally, a high dielectric filler like silicon is used to enhance the dielectric constant of the polymer matrix. However, dielectric properties of polymeric composites are mainly affected by filler size, dielectric constant and volume fraction of filler and polymer [37]. Moreover, extensive research has been performed on the recovery of silicon particles when cutting solargrade ingot using different methods.…”

In solar panel production stage, it is unavoidable to neglect the huge amount of solar grade silicon particles displaced during the slicing of silicon ingot operation. A subject of the present study is to reuse the solar-grade silicon particles as a filler to enhance the mechanical properties of the epoxy-glass fiber polymer composite. Polymer composite was fabricated using a hand-layup method with constant hydraulic pressure by varying filler weight percentages of 0, 1, 3, 5, and 10 %. Particle size and mineralogical features of the recovered silicon particle were characterized by particle size analyser and X-ray diffraction analysis. A positive effect on the mechanical properties of the prepared composites is seen by the recovered silicon particle addition. Maximum tensile strength of 284 MPa has been achieved for the < 10 µm particle with a 5 % weight of silicon filler loaded composite. Both the flexural strength and the hardness of the composites were improved linearly by the addition of the filler material. The dielectric constant is considerably improved by incorporating recovered silicon filler into the epoxy polymer composite. There is a comparatively higher dielectric constant value of 5.96 in a fine silicon particle-filled composite than in a coarse silicon particle-filled composite of 4.8. The sustainable use of silicon wafer cutting particles in polymer composites would mitigate the problems of pollution and minimise the cost of silicon wafer waste disposal as well. This brings up the solution to recycling of silicon wafer cutting waste for a sustainable environment.

Self‐cross‐linkable ferrocenyl‐containing polymethylhydrosiloxanes were synthesized. Karstedt's catalyst and cis‐[PtCl2(BnCN)2] were examined as cross‐linking catalysts at room temperature for the reaction between Si–H groups of the ferrocenyl‐containing polymethylhydrosiloxanes. Cis‐[PtCl2(BnCN)2] is an effective catalyst that allows cross‐linked ferrocenyl‐containing silicones (silicone rubbers) to be obtained with no visible mechanical defects (bubbles or cracks) compared with Karstedt's catalyst. The ferrocene content of the ferrocenyl‐containing silicone rubbers was found to be approximately 50 wt.% by energy‐dispersive X‐ray analysis. Compared with cross‐linked non‐modified polymethylhydrosiloxanes, the ferrocenyl‐containing silicone rubbers exhibited improved tensile properties (the tensile strength increased from 0.47 to 0.75 MPa) and a 1.5–2.5 times lower cross‐linking degree. The surface resistivity of the ferrocenyl‐containing silicone rubbers (50 wt.% ferrocenyl units) was approximately 7 × 109 Ω/□, which was 10,000 times lower than that of pure polymethylhydrosiloxane. The obtained flexible electroactive ferrocenyl‐containing silicone rubbers can potentially be applied as coatings for electronic and electrostatic‐sensitive devices, interfaces, and sensors.
