Head of Raw Rubber Process Development and Chemical Engineering Department of Rubber Research Institute of Sri Lanka (RRISL).

Natural rubber (NR) latex, a polydispersed colloidal dispersion of rubber particles in aqueous medium, commonly extracted from Hevea brasiliensis tree, is converted into soft viscoelastic material, in most cases, with acid coagulation. Natural rubber contains, in addition to rubber hydrocarbon, non rubber substances such as proteins, fatty acids, carbohydrates and mineral salts in small quantities which influence the pr ....etc

Nanoparticles have a very large surface area compared to their volume, so they are often able to react very quickly. This makes them useful as catalysts to speed up reactions. For example, they can be used in self-cleaning ovens and windows. However, there is also the possibility that they might speed up reactions in living things in unpredictable ways, perhaps causing illness or death. ....etc

ABSTRACT
Sensitive skin is a large-area, flexible array of sensors with data processing capabilities, which can be used to cover the entire surface of a machine or even a part of a human body. Depending on the skin electronics, it endows its carrier with an ability to sense its surroundings via the skin s proximity, touch, pressure, temperature, chemical/biological, or other sensors. Sensitive skin devices will make possible the use of unsupervised machines operating in unstructured, unpredictable surroundings among peopl ....etc

Planet Earth is a 2006 British television series produced by the BBC Natural History Unit. Five years in the making, it was the most expensive nature documentary series ever commissioned by the BBC and also the first to be filmed in high definition.

Planet Earth premiered on 5 March 2006 in the United Kingdom on BBC One, and by June 2007 had been shown in 130 countries.

The series comprises eleven episodes, each of which features a global overview of a different biome or habitat on Earth. At the end of each fifty-minute episode, a ten- ....etc

ABSTRACT
Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.
Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordin ....etc

INTRODUCTION
Lithography was the first fundamentally new printing technology since the invention of relief printing in the fifteenth century. It is a mechanical Plano graphic process in which the printing and non-printing areas of the plate are all at the same level, as opposed to intaglio and relief processes in which the design is cut into the printing block. Lithography is based on the chemical repellence of oil and water. Designs are drawn or painted with greasy ink or crayons on specially prepared limestone. The stone is moistene ....etc

Nanotechnology

The use and control of tiny matter is called nanotechnology. The tiny matter is referred to as nanoparticles.
These particles are measured in nanometres (nm). A nanometre is one billionth of a metre (0.000 000 001m). Nanotechnology is concerned with the use and control of structures that are 1-100 nanometres in size.Some of these nanoparticles occur naturally, for example in volcanic ash. Some occur by accident, for example during the combustion of fuels. Many occur by design.
