Principles of Powder Technology

Product Description
Powder technology is extremely important to a wide range of disciplines and industries including food, pharmaceutical manufacturing, minerals and metals processing, among others. Modeled after a short course designed specifically for graduate engineers working in industry, it presents the fundamental engineering properties of materials–essential knowledge for the design and operation of industrial equipment and processes. Contributors–all experts in their fields–provide comprehensive coverage, with a somewhat academic emphasis on the problems involved in handling massive solids, gases and liquids as industry calls for greater expertise in this field.

Drug Delivery

Popular drug delivery methods are non-invasive such as through the mouth, topical (on the skin), ocular, vaginal etc. although not all drugs can be transferred via non-invasive methods, such as protein, which requires delivery by injecting it to the blood circulation.

The most popular method of consuming drugs was and still is orally (pills and liquids).

 

One of the challenging aspects of drug delivery is adjusting these methods to the nature of the drug and the areas and functionalities in the human body that it adheres to tackle.

 

Therefore, the main goal of drug delivery systems is to deploy medications intact to specific parts in the body via a source that can assist controlling and monitoring its effect and success. Thus when referring to drug delivery systems, scientists are attempting to address the problem of reduced therapeutic effects that are caused due to degradation that occurs in the effect of the drug prior it reaching the desired part in the body. One of the solutions to this problem might have been an attempt to locate different targeted areas in the body to inject the drug to, but it may arouse other problems for different areas in the body react differently to different types of medication. (for instance in the stomach, due to low Ph, a medication can be destroyed).

 

The world of nanotechnology – polymeric microspheres, polymer micelles and hydrogel-type materials have proven to be greatly efficient in dealing with drug absorption rates, toxicity etc.

 

The polymeric materials are most popular routes for drug delivery systems research, mainly because the relatively easiness of controlling their chemical and physical properties by researchers.  

 

 

 

Nanomaterials: New Research Developments

Product Description
Nanomaterials is the study of how materials behave when their dimensions are reduced to the nanoscale. It can also refer to the materials themselves that are used in nanotechnology. Materials reduced to the nanoscale can suddenly show very different properties compared to what they exhibit on a macroscale, enabling unique applications. For instance, opaque substances become transparent (copper); inert materials become catalysts (platinum); stable materials turn combustible (aluminum); solids turn into liquids at room temperature (gold); insulators become conductors (silicon). Materials such as gold, which is chemically inert at normal scales, can serve as a potent chemical catalyst at nanoscales. Much of the fascination with nanotechnology stems from these unique quantum and surface phenomena that matter exhibits at the nanoscale. This book presents the latest research from around the globe.
