Nanotechnology involves research and technology development at the 1 nm to 100 nm range. • Nanotechnology builds on the capability to organize or manipulate at the atomic scale. • Nanotechnology creates and uses structures that have novel properties because of their small size. . 2. Nanotechnology Nanoscience involves a study of nanotechnology and nanomaterials, of which at least one of the dimensions is in 1-100 nm range. Over the past two decades, nanomaterials have been a topic of both scientific and
Concurrent to the backlash against parabens, there has been an impetus toward alternative preservatives. Yet, the cosmetics industry responded to this issue by merely tricking their consumers once again. In an effort to remove paraben from the ingredient list, most cosmetic companies replaced parabens for another synthetic preservative, such as phenoxyethanol (Rovan). According to a Montreal pharmaceutical chemist, Ben Kaminsky, phenoxyethanol proves to be nothing but a synthetic compound that reduces

Chapter 1 Introduction 1.1 Background Nanotechnology is a field of applied science, focused on the design, synthesis, characterization and application of materials and devices at the nanoscale. This is an emerging field which plays a major role in the development of innovative methods to produce new products. Because of its greater role in enhancing the performance of several existing technologies, it is gaining high attention. Properties of materials often change dramatically when size reduces
a sustainable design of products or systems in energy and transportation applications. My primary research focuses on designing mechanical systems/components and investigating mechanical interactions between machine components. The treatments required a truly multidisciplinary research effort span the entire mechanical systems and solid mechanics spectrums of mechanical engineering. The research involved design, development, and experimental verifications of mechanical components and systems, and
improvements. Nanotechnology, being one of the century’s popular technologies, is the research and application of miniscule objects in fields ranging from engineering to chemistry. It is conducted at a nanoscale system—a scale that is 1000 times smaller than the components currently used in the microelectronics field (“What is Nanotechnology?”). This technology has led to life-changing developments in the biomedical field, which is a combined area of science, engineering, and medicine, and is applied
new studies examining the possibilities of neural regeneration are not the least of them. The Central Nervous System – consisting of the brain and spinal cord – is perhaps the structure most vital for life in the human body. Unfortunately, it also has one of the slowest and most limited rates of natural regeneration. Damage to the brain or spinal cord or loss of nerve tissue due to degenerative diseases can create life-long physical, cognitive, and psychological debilitation. The devastating implications
The influence of food structure on the delivery of nutrients in the digestive tract 1 Introduction Nutrient refer to any chemical element in the food that can provides energy or be needed for maintenance, growth and development of body; or can result in the changes of physiological or characteristic bio-chemical (Codex, 1987). Normally, for human diet, the nutrients are divided into essential nutrients and non-essential ones. There are six main essential nutrients, including protein, lipid, key
INTRODUCTION Drug delivery Systems Drug delivery systems (DDS) have been developed in order to control pharmacological parameters such as bioavailability, biodistribution and pharmacokinetics of the administered substances. Bioavailability is defined as the percentage of an administered dose of therapeutic agent that becomes available in the systemic circulation in its active form. Drug delivery systems can enhance bioavailability by increasing in-vivohalf-lives of fragile pharmaceuticals e.g. protection
Introduction For decades now Silicon Valley(a nickname for the San Francisco Bay southern region)has been the capital for major US technology firms and has become a thriving ecosystem for innovation. Household names in tech ranging from Apple to WhatsApp continue to drive innovations that improve or replace today’s major industries and business practices. Although many start-up companies fail to gain traction or wide spread success, a handful of companies have risen to world-wide success and multi-billion
