ABSTRACT The cosmetic industry is steadily probing for discovery of new formulations with effective delivery system having biological activity. Nanoscience is one of the widely used technologies and finds its applications in the cosmetic industry. Nanotechnology thus is a transformative and new technical revolution and is being used for alteration of physical properties of an enormous range of products from moisturisers, sun blocks, anti-ageing lotions to liquid make up, hair styling and colouring agents

researches and investigations are required in order to use the nanomaterials in civil engineering and construction sector effectively. Key words: nanomaterials, construction industry, concrete, mechanical strengths, durability I. Introduction Nanotechnology was first introduced by physicist Richard P.

CHEAPTER-1 INTRODUCTION GENERAL- Industrial pollution has become a menace in past many years on the environment, economy, and social aspects. Our construction industries are the major source of pollution accountable for around 4% of particulate emission. The enormous demand of construction industries has highlighted the requirement for sustainable development and intelligent utilization of resources, pointing towards two commonly used materials i.e. cement and nanomaterial there by substantially

The History of Nanocomposites Before the use of nanocomposites, humans have used natural composites to improve their welfare and way of life throughout history. The Mesopotamians would use natural adhesive to glue wood pieces in different ways to make plywood. Archaeologists have found multiple natural composites used by ancient civilizations, but one of the most prevalent was the use of straw. Utilizing straw allowed these civilizations to increase the strength of their building bricks, thus

Research Proposal: Optimum ENP for Oil Spill Remediation Literature Review Summary and Knowledge Gap Oil spill contains crude oil, small amount of heavy metal, refined and unrefined petroleum oil(Intertek, 2015). Due to these toxic chemicals, oil spill is an environmental issue and needs great attention because of its adverse effective in aquatic life and ecological balance. Use of nanomaterials in oil spill remediation is a novice approach. Oil and water separation requires technology with unique

level by monitoring and controlling blood glucose levels to minimize the negative effects of the disease. Because of limitations in diagnostic methods, significant research efforts are focused on developing improved methods to measure glucose. Nanotechnology has impacted these efforts by increasing the surface area of sensors, improving the catalytic properties of electrodes and providing nanoscale sensors. Herein, we discuss the developments in the past several years on both nanosensors that directly

of a vaccination, the syringe gives you a shot of electronics instead. The brain has been implanted with electronics in the past because deep brain stimulation has been used to treat a range of brain disorders for decades. Featured in Nature Nanotechnology, a Harvard research group wants to introduce to the world a thin mesh that is able to track brain activity. Charles Lieber's Lab designed this little device to treat everything from neurodegenerative

NANO SILVER WATER Nanotechnology is a rapidly growing science of producing and utilizing nano-sized particles that measure in nanometers (1nm = 1 billionth of a meter). One nanomaterial that is having an early impact in healthcare product is nano-silver. Nano silver water is almost pure atomic sized particle and de-ionized water with silver in suspension. Approximately 80% of the silver is in the form of metallic silver nano-particles and the remaining silver is in ionic form. The size of silver

A nanoparticle is the most basic component in the construction of a nanostructure. In general, the size of a nanoparticle spans the range between 1 and 100 nm. The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive than other molecules. Self-assembly refers to the process by which nanoparticles or other distinct components spontaneously
