A. * Plant Protection Department, Faculty of Agriculture, Fayoum University, Fayoum, Egypt Department of Economic Entomology and Pesticides, Faculty of Agriculture, Cairo University, Giza, Egypt ABSTRACT Rice is one of the most important food crops for more than half of the world 's population, the rice weevil, Sitophilus
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
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
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
Nanotechnology Nanotechnology is actually a fairly new idea. This may not seem like any big deal in terms of ethics, but just like any type of scientific advancement there are positives and negatives. Of course the ethical issues don't stem out of just the fact that this is a new kind of science. It branches off of "what will this new scientific technology be used for?" For example, Embryonic Stem Cell research. It's not the research that's bad it's how they get the cells. There are half
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.
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
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
us of fungi to support large scale production of acids, biosurfactants and enzymes. In the 1980’s, with the dawn of fresh nanotechnology, fungi had remained important by being able to synthesize nanoparticles. Nanoparticles or nanomaterials are materials including particles or constituents that are of nanoscale proportions, or something that has been produced via nanotechnology. Biologically hazardous or environmentally toxic reducing agents are normally associated in the nanoparticles chemical synthesis
