Recently, research on the use of binary aqueous-organic liquid phase systems for the treatment of polluted air has significantly increased. This paper reports the removal of α-pinene from a waste air stream in a continuous stirred tank bioreactor (CSTB), using either a single-liquid aqueous phase or a mixed aqueous-organic liquid phase. The influence of gas flow rate, load and pollutant concent...

purpose : to compare the cosmetic and functional results of frontalis sling procedure using silicone rod with polytetrafluoroethylene (ptose-up) in congenital ptosis with poor levator function (lf) methods : in a prospective randomized study, 90 eyes of 66 patients with congenital ptosis that underwent frontalis suspension surgery [31 patients (18 unilateral, 13 bilateral cases) using a silicon...

Excitation and emission spectra of PBA were investigated. The concentration dependence of fluorescene was studied showing a maximum intesity at a concentration of 0.039 ± 0.04 mM. 2D-spectroscopy proved the independence of λem on λex. Rayleigh and Raman scattering were observed, showing the shift wavelength νshift = 3800 ± 800 cm−1, which corresponds to the as. st. vibration of water molecules....

Nontuberculous mycobacteria (NTM) are ubiquitous organisms found in soil, water, and biofilms. Engineered surface topography has been proposed as a method to reduce microbial biofilm formation. The Sharklet(®) micropattern silicone surface has been shown to reduce biofilm formation of pyogenic bacteria. We hypothesized that this micropattern surface will also reduce colonization by Mycobacteriu...

Titanium is a successful biomaterial that possesses good biocompatibility. It is covered by a surface layer of titanium dioxide, and this oxide may play a critical role in inhibiting reactive oxygen species, such as peroxynitrite, produced during the inflammatory response. In the present study, titanium dioxide was coated onto silicone substrates by radio-frequency sputtering. Silicone coating ...

Applications of carbon nanotubes (CNTs) like field emission displays, super-capacitors, and cell growth scaffolds can benefit from controllable embedding of the CNTs in a material such that the CNTs are anchored and protrude a desired length. We demonstrate a simple method for anchoring densely packed, vertically aligned arrays of CNTs into silicone layers using spin-coating, CNT insertion, cur...

OBJECTIVES The use of silicone implants in cosmetic and reconstructive surgery has been implicated in the development of autoimmune connective tissue diseases. Previous investigation of the influence of short-term silicone implantation using an experimental model of rheumatoid arthritis revealed no adverse influence upon disease despite the generation of autoantibodies against silicone bound pr...
