Innovation, long the preserve of technocratic elites, is becoming more open. This will be good for the world, argues Vijay Vaitheeswaran alent of 100 miles-per-gallon using alternative energy. The charitable arm of Mr Page's rm has already taken hybrid petrol electric vehicles, like the Toyota Prius, and turned them into even cleaner plug inn versions which can be topped up from an electric soc...

The regeneration of used oil is one the essential processes for economical, industrial and environmental targets. Used rich hydrocarbons, metals (such as: aluminium, chromium, copper, iron, lead, manganese, nickel, silicon tin), gasoline, water antifreeze. Due to high increasing rate number cars, there a huge quantity oil. In this study, different brands were involved in extraction adsorption a...

The importance of gravitational instability in determining the emulsification of vitreal tamponades is discussed. Theoretical results and numerical simulations indicate that the spontaneous formation of water-silicon oil is a rare event and that the very low concentration of surface active agents cannot justify the systematic formation of emulsions. The gravitational instabilities seem to play ...

We investigate the properties of nanometric liquid films with a new noninvasive technique. We measure the spontaneous thermal fluctuations of the free surfaces of liquids to probe their hydrodynamic boundary condition at a solid wall. The surface fluctuations of a silicon oil film could be described with a no-slip boundary condition for film thicknesses down to 20 nm. Oppositely, a 4 nm negativ...

A paraffinoma is a type of inflammatory lipogranuloma that develops after the injection of an artificial mineral oil, such as paraffin or silicon, into the foreskin or the subcutaneous tissue of the penis for the purpose of penis enlargement, cosmetics, or prosthesis. The authors experienced a case of macro-paraffinoma associated with sexual dysfunction, voiding dysfunction, and pain caused by ...

We have used a metastable argon beam to expose gold-coated silicon substrates covered with a self assembled monolayer (SAM) resist. The substrates have been covered with a patterned mask, with feamres of 10 pm size, and exposed to the atomic beam. Subsequent etching revealed negative contrast patterns, consistent with the formation of a negative contamination resist in the SAM, which we attribu...

We experimentally study the spreading of a small volume of silicon oil down a vertical plane with small Bond number. The initial condition is characterized by a horizontal long fluid strip with cross sectional area A and width w(0). We find that the experiments are characterized by a unique nondimensional parameter, R proportional w4(0)/(a2A), where a is the capillary length. An empirical crite...

We address the general question of the extent to which the hydrodynamic behaviour of microscopic freely fluctuating objects can be reproduced by macrosopic rigid objects. In particular, we compare the sedimentation speeds of knotted DNA molecules undergoing gel electrophoresis to the sedimentation speeds of rigid stereolithographic models of ideal knots in both water and silicon oil. We find th...

Introduction: We are developping a micromanipulation line and a spectroscopic method for providing chemical imagery data on Organic Matter (OM) trapped in micrometric grains (Interplanetary Dust Particles, matrix grains extracted from pristine chondrites, STARDUST samples, etc.) The general framwork of our approach is based on the complementarity of Multi Wavelength Raman spectroscopy (includin...
