Rapid and reversible hydrogen storage in clathrate hydrates using emulsion-templated polymers
A method for greatly accelerating the storage of gases such as hydrogen in clathrates by supporting the clathrate phase on a highly macroporous emulsion-templated polymer is presented. The gravimetric penalty is low due to the low bulk d. of the support, no mech. mixing is required, and the system is fully recyclable over multiple charge/discharge cycles.

Computer simulation of conic-shaped patterns on fracture surfaces of polymers
Fractographic analysis, using scanning electron microscopy, is an important method to study polymer fracture behavior. There are several distinctive patterns on
fracture surfaces, such as radial striations, regularly spaced ‘rib’ markings, and conic-shaped patterns. The conic-shaped pattern is the intersection locus of a moving planar crack front and a radially growing circular craze ...

Biodegradable polymers from 5-hydroxylevulinic acid: 1. Synthesis and degradation of poly(5-hydroxylevulinic acid)
As an attempt to synthesize new biodegradable polymers from renewable cellulose resources, melt polycondensation of 5-hydroxylevulinic acid (5-HLA) was reported for the first time. The resulting product, poly(5-hydroxylevulinic acid) (PHLA), was synthesized and characterized with GPC, FTIR, 1H NMR and DSC. The in vitro degradation behaviors in phosphate-buffered saline (PBS) and in deionized water...

Design and synthesis of reactive polymers containing perfluorocyclobutyl (PFCB) and hydroxyl moieties for postfunctionalization of PFCB aryl ether polymers
关键字：Perfluorocyclobutyl (PFCB), Post-functionalization, Reactive polymers
A novel class of perfluorocyclobutyl (PFCB)-containing reactive polymer with adjustable phenolic hydroxyl
contents (PFCB-OH-xx) has been developed. A serial of PFCB-OH-xx polymers with high molecular
weights (Mw > 100,000) and narrow molecular weight distributions (Mw/Mn < 1.15), were facilely prepared
from 2-methoxy-1,4-bis(trifluorovinyloxy)phenyl via thermal cyclopolymerization...

Host Vinyl Polymers Containing Carriers Transporting Groups for Efficient OLEDs
关键字：Host,Vinyl,Polymers,Containing,Carriers,Transporting,Groups,Efficient,OLEDs,
Electron-transport in conventional PVK host is much more difficult than hole-transport, resulting in imbalanced carriers transport. In order to overcome this problem, it is necessary to enhance electron transport rate by incorporating elect...

Use of Biodegradable Polymers to improve new Antifouling coatings :Erosion of marine paints
关键字：Use,Biodegradable,Polymers,improve,new,Antifouling,coatings,Erosion,marine,paints,
It is generally agreed that the prevention of marine fouling can be achieved by coatings from which a controlled release of toxic molecules prevents the growth of adhered organisms (bacteria, algae, molluscs)by killing them.
