Influence of aging conditions on textural properties of water-glass-based silica aerogels prepared at ambient pressure
(Springer US, 2010-06-04)
The experimental results of aging time and temperature on the textural properties of water-glass (sodium
silicate)-based silica aerogels are reported and discussed. Aging of the hydrogel for different times and temperatures
led ...
Release Kinetic Models of Vanillin and Physicomechanical Properties of Thermoplastic Starch and Chitosan Nanocomposite Films: Effects of Mixing Order
(Springer Nature Switzerland AG., 2020-02-20)
The effects of mixing sequence of starch–chitosan nanocomposite films on antimicrobial properties of vanillin, the release kinetics of vanillin, and physicomechanical changes of films have been reported. Four types of films ...
Meticulous Overview on the Controlled Release Fertilizers
(Hindawi Publishing Corporation Advances in Chemistry, 2014-08-28)
Owing to the high demand for fertilizer formulations that will exhaust the possibilities of nutrient use efficiency (NUE), regulate
fertilizer consumption, and lessen agrophysicochemical properties and environmental adverse ...
Encapsulated Urea-Kaolinite Nanocomposite for Controlled Release Fertilizer Formulations
(Hindawi Publishing Corporation Journal of Chemistry, 2015)
Urea controlled release fertilizer (CRF) was prepared via kaolinite intercalation followed by gum arabic encapsulation in an attempt
to reduce its severe losses associated with dissolution, hydrolysis, and diffusion. ...
Dynamics of Kaolinite-Urea Nanocomposites via Coupled DMSO-Hydroxyaluminum Oligomeric Intermediates
(Hindawi Publishing Corporation Indian Journal of Materials Science, 2015)
Kaolinite-urea nanocompositeswere prepared via intercalation reactions in an attempt to investigate the dynamic nature of kaolinite
morphology for advanced applications in controlled release systems (CRS). Characterization ...
A review on strategies to optimize metabolic stages of anaerobic digestion of municipal solid wastes towards enhanced resources recovery
(BioMed Central Ltd, 2019-12-17)
Recently, there are increased efforts by municipals and researchers to investigate the potential of utilizing municipal solid wastes (MSW) for resources recovery. In many parts of developing countries, MSW is mostly collected ...
Enhancement of porosity of sodium silicate and titanium oxychloride based TiO2–SiO2 systems synthesized by sol–gel process and their photocatalytic activity
(Elsevier, 2013-09-15)
The textural properties of TiO2–SiO2 composites (TSCs) were successively enhanced using three approaches; (1) washing the hydrogels with different solvents, (2) using surfactant and (3) forming the TiO2 sol in ethanol ...
Synthesis and characterization of micrometer-sized silica aerogel nanoporous beads
(Elsevier, 2012-08-15)
Here we report the preparation of micrometer-sized highly nanoporous, relatively trasperant silica aerogel beads with high surface area as well as large pore volume with sizes ranging from 165 to 395 μm. The wet micrometer-sized ...
Quantitative recovery of high purity nanoporous silica from waste products of the phosphate fertilizer industry
(Elsevier, 2013-01-25)
This study reports on the quantitative recovery of high purity nanoporous silica from wastes material (H2SiF6) of the phosphate fertilizer industry and Na2O·SiO2. The silica recovered from the wastes was compared with ...
Synthesis of mesoporous silica with superior properties suitable for green tire
(Elsevier, 2012-09-25)
In this article we report synthesis of mesoporous silica with superior properties for application in green tire (environmentally friendly tire) as filler. The synthesis was done using a newly innovated apparatus which ...
