A study of HAp/PLLA composite as a substitute for bone powder, using FT-IR spectroscopy
(Elsevier Science Ltd, 2001)
Chemically synthesized hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial was studied in vivo. The biocomposite was implanted into Balb/c Singen mice and after 1 and 3 weeks removed from their organisms and ...
Pressure drop in a countercurrent gas-flowing solids-packed bed contactor
(American Chemical Society, 2001)
The equations for prediction of pressure drop in countercurrent gas-flowing solids-packed bed contactors are proposed. The correlations are based on all available data for various constructions, packing elements, and gas ...
Characterization of antifungal citrus pectin-based films for potential agricultural application
(Elsevier B.V., 2023)
In this study, pectin-based films blended with alginate and crosslinked with copper ions for potential application in agriculture were investigated. Copper was selected as crosslinking agent, due to its key role as a plant ...
Application of carbonized hemp fibers as a new solid-phase extraction sorbent for analysis of pesticides in water samples
(Elsevier Science Sa, Lausanne, 2012)
There is a growing interest in utilization of abundantly available materials, bio-mass or industrial byproducts, as precursors for the preparation of carbon materials. Short hemp fibers, acquired as waste from textile ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Elsevier, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H2 oxidation reaction (HOR) at MoOx-Pt electrode in 0.5 mol dm-3 HClO4 saturated with H 2 containing 100 ppm CO, was examined on rotating disc electrode ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
Solar-driven thermo-photocatalytic CO2 methanation over a structured RuO2:TiO2/SBA-15 nanocomposite at low temperature
(Elsevier B.V., 2024)
A new hybrid catalyst composed of mesostructured silica SBA-15 functionalized with TiO2 and further loaded with RuO2 was developed to efficiently promote thermo-photocatalytic CO2 hydrogenation into methane at low temperatures. ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier Sci Ltd, Oxford, 2019)
Highly ordered, anodically grown TiO2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping ( lt = 2 at.%) in the titanium oxide lattice. FESEM micrographs revealed ...
Obtaining jute fabrics with enhanced sorption properties and "closing the loop" of their lifecycle
(Industrial Crops and Products, 2021)
The objective of this investigation was to obtain jute fabrics with enhanced sorption properties (by using simple and cost-effective alkali and oxidative modifications) and a long life cycle. The applied alkali modifications ...
Determination of inorganic arsenic species in natural waters-Benefits of separation and preconcentration on ion exchange and hybrid resins
(Analytica Chimica Acta, 2010)
A simple method for the separation and determination of inorganic arsenic (iAs) species in natural and drinking water was developed. Procedures for sample preparation, separation of As(III) and As(V) species and preconcentration ...
