Abstract Objectives In this study, a collagen-rich biomembrane obtained from porcine intestinal submucosa for application in guided bone regeneration was developed and characterized. Then, its biological and mechanical properties were compared with that of commercial products (GenDerm [Baumer], Lumina-Coat [Critéria]…
Technological aspects of the formation of wear- and corrosion-resistant coatings on aluminum alloys and steel via an integrated use of methods of the low-temperature heterophase transfer, microarc oxidation, and magnetron sputtering. The tribological and anticorrosion properties of the coatings developed were estimate…
There is a heighten interest on natural fiber reinforced polymer composites to achieve superior, mechanical properties. However, such composites are limited due to the poor compatibility between natural-fiber reinforcement and polymer matrices. An enhanced fiber-polymer interface compatibility was achieved for microcr…
Abstract The creation of materials that ensure high reliability and environmental safety of Arctic structures under extremely harsh operating conditions is an urgent scientific and technical task. This article deals with the creation of domestic aromatic polysulphons to create on their basis polymer construction mater…
Abstract The most gelatin is derived from porcine skins and bones that accounted for 46% of total gelatin. This is an obstacle to the development of food products in a Muslim country like Indonesia. One of the prospective source to be developed is fish bones that account for 10-20% of fish weight, with the highest cul…
It was recently shown that molecularly dispersed octaisobutyl -polyhedral oligomeric silsesquioxane (bu-POSS) nanoparticles acted like nanoplugs and reduced O 2 transmission in low-density polyethylene (LDPE) ( Romo-Uribe, A.; Polymer 2019, 165, 61−71, DOI: 10.1016/j.polymer.2019.01.024 ). Here, the influence of alkyl…
A more accurate cesium hydroxide (CsOH)-chemisorption model is required to improve the estimation of the Cs distribution in Fukushima Daiichi Nuclear Power Station by severe-accident (SA) analysis codes. The current CsOH-chemisorption model incorporated in SA analysis codes was developed with insufficient information…
Tunable-band-gap colloidal QDs are a potential building block to harvest the wide-energy solar spectrum. The solution-phase surface passivation with lead halide-based halometallate ligands has remarkably simplified the processing of quantum dots (QDs) and enabled the proficient use of materials for the development of…
A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging from 800 to 950 °C to fabricate dense pollucite ceramics. It was found that the application of ex…
Cone calorimetry experiments of on flexible polyurethane foam and flexible polyurethane foam covered with a variety of fire-blocking barrier fabrics were used to characterize and rank the effectiveness of barrier fabrics with the ultimate goal being an ability to predict the effectiveness of barrier fabrics for reduci…
Abstract Zinc-aluminum Layered double hydroxide was synthesized by copercipitation method in molar ratio Zn/Al 3:1.The prepared layered double hydroxide were characterized by Fourer-transform infrared spectra (FTIR), X-ray diffraction (XRD)and Atomic force microscope (AFM).The synthesized layered double hydroxides wer…
Abstract The aim of the research is to enhance the specifications of adhesives used in the treatment of cracks in the walls of buildings and concrete ceilings in addition to the oxide zirconium nanoparticles. Use epoxy resins and added ZrO2 by weight ratio (0, 1, 3, 5, 7, and 9)%and using the in situ method for Prepar…
Abstract In this work, a scalable thermal imprinting method that allows to directly fabricate superhydrophobic polymer surfaces with superstrong resistance to harsh cleaning and mechanical abrasion is reported. A titanium (Ti) mold is produced by femtosecond laser processing to possess a hierarchical micro‐ and nanosc…
Targeting angiogenesis in the microenvironment of a tumor can enable suppression of tumor angiogenesis and delivery of anticancer drugs into the tumor. Anti-angiogenesis targeted delivery systems utilizing passive targeting such as Enhanced Permeability and Retention (EPR) and specific receptor-mediated targeting (act…
CO emission is one of biggest problem in environmental sector due to increasing number of motorcycle user in every years. CO is poison gas which directly affects on the public health and earth’s atmosphere. The aim of this research to developed catalyst in catalytic converter system to oxidize CO to CO2 by using MnO2/…
Since the proposal of metamaterials by Rodger Walser in 1999, the recent twenty years have witnessed the rapid development of various metamaterials and 2D metasurfaces in a wide range of frequency bands covering the microwave, terahertz, infrared, visible and ultraviolet. Metamaterials exhibit unusual electromagnetic…
Borophene, the lightest elemental Dirac material, is realized experimentally in free-standing form by solution-phase synthesis by Prashant Kumar, Ajayan Vinu, and co-workers, as described in article number 1900353. Various sensing applications are demonstrated, such as in SERS-based molecular sensing, gas sensing, pho…
In article number 1901171, Won Suk Shin, Jae Won Shim, and co-workers report on ambient energy harvesting using organic photovoltaics (OPVs). The great indoor performance of the OPVs derived from their excellent optical and electrical properties allows them to serve as efficient semi-permanent self-powering systems fo…
