Degradable elastomer composites containing layered silicate

Lipinska M., Zaborski M., Technical University of Lodz, PL

Polymers with an increased degree of degradability can be obtained through the addition of natural biodegradable supplements to the synthetic polymer. The aim of our study was to obtain an elastomeric composites determined time of [...]

Measuring Degradation Processes of Model Coatings Related to Bioenergy Applications

Dixon M.C., Oom A., Q-Sense a Division of Biolin Scientific, US

Degradation mechanisms are relevant to a wide variety of applications including the bioenergy, biomaterial, semiconductor, and detergent industries. Therefore, it is of interest to study these mechanisms, for example, to better tailor formulations for enzymatic [...]

Adhesion of moulding compounds. Can material pre-selection increase the reliability of electronic components?

Pufall R., Michel B., Kaulfersch E., Infineon Technology AG, DE

It is well known that high temperature storage can degrade moulding compounds for chip encapsulation to such an extent that the adhesions to surfaces like copper (lead frames) or polyimide (chip coating) decreases drastically causing [...]

Conducting Polymer Nanocomposites: Role of DNA Functionalized Carbon

Cheung W., Bogozi A., Ma Y., Mao G., Mao G., He H., Rutgers University, US

In this work, a water-soluble self-doped polyaniline nanocomposite was fabricated by in-situ polymerization of 3-aminophenylboronic acid monomers in the presence of single-stranded DNA dispersed- and functionalized- single-walled carbon nanotubes. For the first time, we found [...]

Less Harmful Acidic Degradation of Poly(lactide-co-glycolide) Bone Tissue Engineering Scaffolds through Titania Nanoparticle Addition

Liu H., Slamovich E.B., Webster T.J., Purdue University, US

In the last ten years, biodegradable aliphatic polyesters, such as poly(lactide-co-glycolide) acid (PLGA), have attracted increasing attention for their use as scaffold materials in bone tissue engineering because their degradation products can be removed by [...]

The role of the synthetic procedure on the photoactivity of nanocrystalline TiO2

Ardizzone S., Bianchi C.L., Cappelletti G., Pirola C., Ragaini V., University of Milan, IT

The nanometer scale of the TiO2 plays a key role in affecting the photocatalytic performance of the material. In recent years a great deal of activity was dedicated, by the authors, to the study of [...]

pH-Responsive Hydrogel with Controlled Swelling and Degradation Rate

Trujillo-Lemon M., Bowman C.N., Stansbury J.W., University of Colorado Denver and Health Sciences Center, US

Degradable polymeric materials that can be storage for months in aqueous enviroment before undergoing on-command controlled swelling and degradation were prepared and their kinetics of swelling and degradation were evaluated. The swelling and degradation rates [...]
