IJzersterk biopolymeer: We schrijven en printen erop, pakken ermee in en vegen er viezigheid mee schoon. En in Japan bouwen ze er zelfs huizen van. Het bestaat vrijwel uitsluitend uit cellulose, een natuurlijk biopolymeer en het hoofdbestanddeel van hout. We verbruiken gemiddeld 200 kg papier per persoon per jaar. Papier wordt gemaakt van verse houtvezels en hergebruikt papier. Krantenpapier en kartonnen dozen bestaan zelfs helemaal uit oud papier. We zamelen in Nederland namelijk vrijwel al het recyclebare papier in.Toch zijn er nog veel bomen nodig om de grondstof aan te vullen. De papierindustrie plant weliswaar steeds nieuwe bomen, maar jaarlijks wordt wel circa 10 km2 bos gekapt voor het papier dat we in Nederland gebruiken. Bovendien is er 10 liter water nodig om 1 kg papier te maken. Het water zuiveren en het verse papier drogen kost veel energie. De papierindustrie zoekt dan ook naar zowel alternatieve grondstoffen als duurzamer oplossingen. Zo kunnen stengels van bijvoorbeeld tomatenplanten of tarwestro als grondstof dienen voor kartonnen dozen. En uit het proceswater van de papierfabriek kun je allerlei waardevolle verbindingen terugwinnen, zoals vetzuren. De eerste voorzichtige stappen zijn gezet om cellulose terug te winnen uit ons huishoudelijk afvalwater.

The concept of Focal Drug Delivery has been applied for treating illnesses that are localized to a certain tissue or organ. These delivery systems are applied directly to the diseased site and deliver a desired dose for an extended time period while minimizing systemic distribution of toxic drug. Despite the upsurge of interest in focal targeted drug delivery, there is currently no single reference text on this subject.  Thus, the aim of the proposed book “Focal Controlled Drug Delivery” is to bring together leading experts and researchers in this field to provide an authoritative account of the essential pharmaceutical, technological, physiological and biological sciences underpinning the topic.  This book contains two sections- first section includes fundamental introductory chapters for focal drug delivery whereas, second section includes chapters describing drug delivery to body sites/system. The book allows clinical, pharmaceutical and biological scientists to offer their own perspectives on the subject, making it of potential interest to a wider audience than just drug delivery scientists. ABRAHAM J. DOMB is Professor for Medicinal Chemistry and Biopolymers at the Faculty of Medicine of the Hebrew University, Jerusalem, Israel. He earned Bachelor’s degrees in Chemistry, Pharmacy and Law studies and PhD degree in Chemistry from Hebrew University. He did his postdoctoral training at MIT and Harvard Univ. USA and was R&D manager at Nova Pharm. Co. Baltimore USA during 1988-1992. During 2007-2012 he headed the Division of Identification and Forensic Sciences of the Israel Police. His primary research interests are in biopolymers, controlled drug delivery, cancer therapy, nanoparticulate systems, and forensic sciences. WAHID KHAN obtained his Master’s and PhD in Pharmaceutics at the National Institute of Pharmaceutical & Educational Research (NIPER) Mohali India and worked with Prof. Abraham J. Domb in The Hebrew University of Jerusalem, Israel for his post doctoral research. Currently, he is working as Assistant Professor in Department of Pharmaceutics, NIPER, Hyderabad, India. He is having experience of working in areas of drug delivery, drug targeting, nanomedicine and biodesign of implantable medical devices. Dr. Khan has also won various national and international awards and fellowships including- Israel government prestigious PBC fellowships for outstanding Post-doctoral Researcher, Valazzi-Pikovsky and Lady Davis fellowship award.

Processing of polymer nanocomposites usually requires special attention since the resultant structure—micro- and nano-level, is directly influenced by among other factors, polymer/nano-additive chemistry and the processing strategy. This book consolidates knowledge, from fundamental to product development, on polymer nanocomposites processing with special emphasis on the processing-structure-property-performance relationships in a wide range of polymer nanocomposites. Furthermore, this book focuses on emerging processing technologies such as electrospinning, which has very exciting applications ranging from medical to filtration. Additionally, the important role played by the nanoparticles in polymer blends structures has been illustrated in the current book, with special focus on fundamental aspects and properties of nanoparticles migration and interface crossing in immiscible polymer blend nanocomposites. This book focuses heavily on the processing technologies and strategies and extensively addresses the processing-structure-property-performance relationships in a wide range of polymer nanocomposites, such as commodity polymers (chapter 1), engineering polymers (chapter 2), elastomers (chapter 3), thermosets (chapter 4), biopolymers (chapter 5), polymer blends (chapter 6), and electrospun polymer (chapter 7). The important role played by nanoparticles in polymer blends structures in particular is illustrated. The book is useful to undergraduate and postgraduate students (polymer engineering, materials science & engineering, chemical & process engineering), as well as research & development personnel, engineers, and material scientists.
