pH-Sensitive Hydrogels Based on (Meth)Acrylates and Itaconic Acid
(Polymer Soc Korea, Seoul, 2014)
Novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA), itaconic acid (IA) and different poly (alkylene glycol) (meth)acrylates (PAGM) (P(HEMA/IA/PAGM)) were synthesized. We investigated the influence of different ...
The enhanced removal of cationic dyes in binary system using novel copolymers with two kinds of acidic groups
(Elsevier Science Bv, Amsterdam, 2015)
In this study novel copolymer hydrogels based on methacrylic acid (MAA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) were synthesized by free-radical aqueous copolymerization and characterized. Derived P(MAA-co-AMPS) ...
Immobilization of horseradish peroxidase onto kaolin
(Springer, New York, 2016)
Kaolin showed as a very perspective carrier for the enzyme immobilization and it was used for the adsorption of horseradish peroxidase (HRP). The effects of the enzyme concentration and pH on the immobilization efficiency ...
Testing of the efficiency of military devices for personal respiratory protection in relation to sub-micron particles of biological agents
(Inst Materials Physics, Bucharest, 2012)
The construction of biological weapons and tactics of its application dictate that dissemination of biological agents on the target has to be in the form of aerosols. The work was done on the effectiveness of filtration ...
Influence of Microwave Heating on the Polymerization Kinetics and Application Properties of the PMMA Dental Materials
(Wiley, Hoboken, 2011)
The effects of heating mode (conventional isothermal heating (CIH) and microwave isothermal heating (MWIH) on the kinetics of polymerization and the properties important for the application (residual monomer, hardness, and ...
Silicon nanostructuring by Ag ions implantation through nanosphere lithography mask
(Elsevier Science Bv, Amsterdam, 2019)
Nanosphere lithography is an effective technique for high throughput fabrication of well-ordered patterns on large areas. This study reports on nanostructuring of silicon samples by means of Ag ions implantation through ...
A novel chitosan gels: Supercritical CO2 drying and impregnation with thymol
(Wiley, Hoboken, 2018)
Supercritical carbon dioxide (scCO(2)) technology was used for preparation of functional pH sensitive chitosan-based aerogels characterized with micron size pores and their impregnation with thymol as a natural bioactive ...
Sugar Beet Pulp as Leuconostoc mesenteroides T3 Support for Enhanced Dextransucrase Production on Molasses
(Humana Press Inc, Totowa, 2016)
Sugar beet pulp (SBP) and molasses, as an agro industrial waste material, are produced in large amounts annually. Thus, a major challenge nowadays is to develop procedures that could increase the value of the generated ...
A study of the removal of copper ions from aqueous solution using clinoptilolite from Serbia
(Springer, New York, 2011)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not ...
Ultrasound Pretreatment as an Useful Tool to Enhance Egg White Protein Hydrolysis: Kinetics, Reaction Model, and Thermodinamics
(Wiley, Hoboken, 2016)
The impact of ultrasound waves generated by probe-type sonicator and ultrasound cleaning bath on egg white protein susceptibility to hydrolysis by alcalase compared to both thermal pretreatment and conventional enzymatic ...
