Publication date: 15 April 2019Source: Journal of Alloys and Compounds, Volume 781Author(s): Zaixing Yang, Hong Sun, Hongren Li, Feng Li, Huang Qijing, Yan ZhangAbstractIn this paper, we report on a hydrogen storage material: MnO2 hollow spheres and ammonia borane (MHS/AB) composite, which is fabricated by a simple liquid mixing method. The BET, SEM and TEM results show that AB is well loaded in the MnO2 hollow spheres. The thermal dehydrogenation processes are investigated by thermogravimetry (TG), Differential scanning calorimetry (DSC), temperature programmed desorption/mass spectrometer (TPD/MS) measurements. The resul...

Publication date: Available online 8 December 2018Source: Journal of Molecular StructureAuthor(s): Haleh Mohebali, Abdolghafar Abolhosseini Shahrnoy, Ali Reza MahjoubAbstractHerein the potential use of cesium salts of polyoxometalate incorporated ceria and magnetic ceria as a photocatalyst for the photodegradation of Congo red was studied. Polyoxometalates salts (cesium salts of tungestophosphoric acid (H3PW12O40), molybdophosphoric acid (H3PMo12O40), and 6-molybdo tungestophosphoric acid (H3PW6Mo6O40)), having Keggin structure with large cations like Cs+, are porous materials. The morphological and structural studies of s...

Authors: Lee YN, Moon JH, Choi HJ Abstract Recent advances in cholangiopancreatoscopy technology permit image-enhanced endoscopy (IEE) for pancreatobiliary diseases. There are limitations in endoscopy performance and in the study of the clinical role of IEE in bile duct or pancreatic duct diseases. However, currently available IEEs during cholangiopancreatoscopy including traditional dye-aided chromoendoscopy, autofluorescence imaging, narrow-band imaging, and i-Scan have been evaluated and reported previously. Although the clinical role of IEE in pancreatobiliary diseases should be verified in future studies, IEE ...

CONCLUSION: Reducing interimplant distance may decrease global linear distortions (dR) for intraoral scanner systems, but had no effect on Impregum and the dental laboratory scanner systems. Impregum consistently exhibited the best or second-best accuracy at all implant locations, while True Definition exhibited the poorest accuracy for all linear distortions in both Models A and B. Impression systems could not be consistently ranked for absolute angular distortions. PMID: 30521661 [PubMed - as supplied by publisher]

Authors: Smeets R, Henningsen A, Heuberger R, Hanisch O, Schwarz F, Precht C Abstract PURPOSE: To compare the influence of ultraviolet (UV) irradiation and cold atmospheric pressure plasma (CAP) treatment on surface structure, surface chemistry, cytocompatibility, and cell behavior on zirconia in vitro. MATERIALS AND METHODS: Zirconia samples (TZ-3YSBE) were treated by UV irradiation, oxygen plasma, or argon plasma for 12 minutes each and compared with the nontreated samples. Surface analysis was conducted using scanning electron microscopy, roughness analysis, and x-ray photoelectron spectroscopy. Cell prolife...

CONCLUSION: This study demonstrated that morphologic, elemental, and biochemical modifications of periimplant bone can be studied using micro-ATR FTIR, SEM-EDS, and micro-CT. The complement of these techniques can be considered a new multipurpose approach to investigate bone affected by peri-implantitis. PMID: 30521655 [PubMed - as supplied by publisher]

This study aimed to investigate the in vitro and in vivo bone-forming potential of a sandblasted, large-grit, acid-etched (SLA) titanium (Ti) surface treated with a laminin-derived functional peptide, PPFEGCIWN (DN3). MATERIALS AND METHODS: Human osteoblast-like MG63 cells were cultured with SLA Ti discs untreated or treated with DN3 or a control scrambled peptide (SP). Cell adhesion, spreading, and viability on the discs were tested. Alkaline phosphatase gene expression and enzyme activity were also evaluated. Four DN3-coated SLA Ti implants and four untreated implants were placed into the tibiae of two rabbits (two i...
