BACKGROUND The optimal therapy for in-stent restenosis (ISR) is controversial. We evaluated three different strategies for the treatment of in-stent restenosis: cutting balloon angioplasty (CBA), paclitaxel-eluting balloon angioplasty (PEBA) and cutting balloon followed by paclitaxel-eluting balloon angioplasty (CB+PEBA). METHODS Forty-five coronary arteries in 45 mini-pigs underwent oversize...

Because of the high separation performance and easy preparation, mixed-matrix membranes (MMMs) consisting of metal-organic frameworks have received much attention. In this article, we report a novel ZIF-300/PEBA MMM consisting of zeolite imidazolate framework (ZIF-300) crystals and polyether block amide (PEBA) matrix. The ZIF-300 crystal size was effectively reduced by optimizing the hydrotherm...

In this work, poly (ether-block-amide) (PEBA)/ceramic hollow fiber (HF) composite membranes with high flux were prepared by dip-coating the ceramic hollow fiber with PEBA polymer solution for pervaporation (PV). The membrane fabrication was optimized by finely tailoring the coating parameters such as the viscosity and concentration of PEBA coating solution, which made the pervaporation flux as ...

Mixed matrix membranes containing metal-organic frameworks have attracted large attention owing to the combined advantages of high separation performance and easy processability. In this work, CO2-philic zirconium metal organic framework UiO-66 and UiO-66-NH2 nanocrystals were synthesized and embedded into polyether block amide (PEBA) polymer membranes for CO2 separation. It can be found that a...

Graphene oxide (GO)-polyether block amide (PEBA) mixed matrix membranes were fabricated and the effects of GO lateral size on membranes morphologies, microstructures, physicochemical properties, and gas separation performances were systematically investigated. By varying the GO lateral sizes (100–200 nm, 1–2 lm, and 5–10 lm), the polymer chains mobility, as well as the length of the gas channel...

Pervaporation membrane technology plays an important role in production of renewable bio-fuels. To improve the separation performance of polymeric membranes, an effective approach is development of mixed-matrix membranes containing high-performing fillers such as metal-organic frameworks. Towards practical application, hollow fiber could be an ideal substrate for mixed-matrix composite membrane...

Although the oceanic cyanobacterium Prochlorococcus harvests light with a chlorophyll antenna [1-3] rather than with the phycobilisomes that are typical of cyanobacteria, some strains express genes that are remnants of the ancestral Synechococcus phycobilisomes [4]. Similarly, some Prochlorococcus cyanophages, which often harbor photosynthesis-related genes [5], also carry homologs of phycobili...

We present investigations on noncovalent bonding and supramolecular self-assembly of two related molecular building blocks at a noble metal surface: 4-[trans-2-(pyrid-4-yl-vinyl)]benzoic acid (PVBA) and 4-[(pyrid-4-yl-ethynyl)]benzoic acid (PEBA). These rigid, rodlike molecules comprising the same complementary moieties for hydrogen bond formation are comparable in shape and size. For PVBA, the...

We introduce the ML-Peba system, a system which generates textual descriptions of animals in both English and Spanish from an abstract knowledge base. The system relies upon a phrasal lexicon for linguistic realization. The paper discusses the pros and cons of this approach for multilingual generation, suggesting that its use enables a more language-independent knowledge representation than mos...

As an alternative energy source to fossil fuels, biobutanol has received increasing attention. In this work, new mixed matrix membranes (MMMs) incorporating zeolitic imidazolate frameworks (ZIF-71) particles into polyether-block-amide (PEBA) were prepared for biobutanol recovery from acetone–butanol–ethanol (ABE) fermentation broth by pervaporation (PV). FESEM, EDS, XRD, FT-IR, DSC and contact ...
