Biodegradable polymers such as polylactic acid (PLA) are used nowadays due to their degradability, durability and environmentally friendly properties. Alkaline surface treatment of natural fibres is used to increase the flexural properties of composites. ... see more

Biodegradable polymers play a very important role in plastic engineering by replacing non biodegradable, non renewable petrol based polymers. Starch is a renewable, biodegradable, low cost natural polymer with high availability. Natural polymers can be bl... see more

BACKGROUND: Many randomised control studies showed that percutaneous coronary interventions using biodegradable-polymer drug-eluting stents (DES) offer a safe and effective alternative to durable-polymer DES. However, not many studies have discussed its u... see more

The objective of this work was to manufacture biodegradable films based on polyvinyl alcohol (PVA) and also to evaluate the effect of the different degrees of hydrolysis (DH) and degrees of polymerization (DP) of PVA on the properties of these films. Four... see more

Polymer flooding could enhance the oil recovery by increasing the viscosity of water, thus, improving the mobility control and sweep efficiency. It is essential to explore natural sources of polymer, which is biologically degradable and negligible to envi... see more

This research seeks to improve the fertilizer use efficiency, particularly potassium nutrient, and to minimize any possible dose losses. The improvement was applied by the use of foliar sprays by encapsulated potassium element into biodegradable polymer. ... see more

In this work we present Multi-Photon Polymerization fabrication technique for biomedical applications. Optimal structuring parameters were defined in different polymeric materials using various lasers with different pulse durations (8 ps, 300 fs... see more

Materials able to decompose safely are very important for solving the environmental problems. In this paper the preparation conditions of biodegradable film based on polyvinyl alcohol (PVA) and starch were studied. IR-spectroscopy analysis showed that dur... see more

Ocular drug delivery has been a major challenge for clinical pharmacologists and biomaterial scientists due to intricate and unique anatomical and physiological barriers in the eye. The critical requirement varies from anterior and posterior ocular segmen... see more
