BIODEGRADABLE PLASTIC (PHB) FROM BACTERIA COLLECTED FROM GOPALPUR BEACH, BHUBANESWAR [PDF]
, 2020 Objective: Environmental concerns have prompted research into the development of biodegradable polymer as an alternative to petroleum-based plastics. Polyhydroxybutyrates (PHBs) are good alternatives to produce biodegradable plastics.

Three‐Dimensional Piezoelectric Fibrous Constructs for Muscle Regeneration
Small, EarlyView.This study fabricates 3D piezoelectric PHBV scaffolds to enhance muscle regeneration by systematically tuning electrospinning parameters. Introducing porosity yields a 25‐fold enhancement in the effective piezoelectric coefficient (d33). A highly effective d33 signal, activated by cellular tension and fiber deformation, significantly improves myogenic ...

Preparation and characterization of PHB blended with modified soluble starch
, 2010 碩士本研究利用溶液摻混與熔融摻混法製備生物可分解塑膠聚羥基丁酯與澱粉接枝聚醋酸乙烯酯PHB/PVAc-modified Starch聚掺合體，探討其相容性並測量其性質，因為PHB成本過高，於是藉著摻合同樣具有生物可分解性但價格便宜的澱粉以大幅降低成本。而為了增加澱粉和PHB的相容性，於是將和PHB相容的PVAc接枝到澱粉上，為了增加接枝比值，將硝酸銨鈰起始劑溶解在不同濃度之硝酸溶液中，探討硝酸濃度對單體轉化率，接枝效率和接枝比值的影響。將接枝比值最高(0.223)的改質澱粉(SV3 ...

High Voltage, EarlyView.ABSTRACT Artificial intelligence computing, renewable energy integration and transportation electrification are driving electrical and electronic equipment towards higher power densities, higher voltage ratings and greater miniaturisation. Under these trends, insulation systems have become a key bottleneck for reliability and compactness.

Progressive Convex Hull Simplification
Computer Graphics Forum, EarlyView.Abstract Convex hulls are useful as tight bounding proxies for a variety of tasks including collision detection, ray intersection, and distance computation. Unfortunately, the complexity of polyhedral convex hulls grows linearly with their input. We consider the problem of conservatively simplifying a convex hull to a specified number of half‐spaces ...

Telechelic Polyhydroxyalkanoates/Polyhydroxybutyrates (PHAs/PHBs)
, 2017 Poly(3-hydroxyalkanoate)s, PHAs, are natural polyesters collected as intracellular granules as a result of a metabolic stress upon unbalanced growth, owing to a limited supply of a necessary nutrient and to the presence of an excess of a carbon source [1,2,3,4,5,6,7-8]. PHAs have material properties ranging from rigid and highly crystalline to elastic,

Effects of climate change on marine biodiversity on the western Atlantic coast
Conservation Biology, EarlyView.Abstract The current climate crisis, driven by greenhouse gas emissions, threatens global biodiversity, including that in marine ecosystems. However, projections for the western Atlantic Ocean that jointly quantify species richness and endemism while accounting for spatially biased and incomplete occurrence data remain limited.
