Analysis of inquiry materials to explain complexity of chemical reasoning in physical chemistry students’ argumentation
(Springer, Science and Technology Education LibraryWiley Periodicals, Inc., 2017-12)
One aim of inquiry activities in science education is to promote students’ participation in the practices used to build scientific knowledge by providing opportunities to engage in scientific discourse. However, many factors ...
Gellan gum–O,O′‐bis(2‐aminopropyl)‐polyethylene glycol hydrogel for controlled fertilizer release
(Academic PressWiley Periodicals, Inc., 2018-01-10)
A gellan gum–Jeffamine superabsorbent hydrogel was obtained with different crosslink densities using different amounts of (1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide hydrochloride) and N‐hydroxysuccinimide. Infrared ...
Synthesis and performance of a thermosetting resin: Acrylated epoxidized soybean oil curing with a rosin‐based acrylamide
(Wiley Periodicals, Inc., 2017-03-05)
A synthesized rosin‐based polymeric monomer, N‐dehydroabietic acrylamide (DHA‐AM), was introduced into an acrylated epoxidized soybean oil (AESO)/DHA‐AM system to afford a thermosetting resin through thermocuring. Different ...
Microencapsulation of imidazole curing agent by solvent evaporation method using W/O/W emulsion
(Wiley Subscription Services, Inc., A Wiley Company, 2013-08-05)
The epoxy–imidazole resin system is used to form the anisotropic conducting film. The latent character of the system is very significant. In this study, imidazole (Im) or 2‐methylimidazole (2MI) was encapsulated for the ...
Examining student work for evidence of teacher uptake of educative curriculum materials
(Wiley Periodicals, Inc.Lawrence Erlbaum Associates, 2015-08)
The purpose of this study was to identify evidence in student work of teachers' uptake of educative features in educative curriculum materials. These are features in curriculum materials designed with the specific intent ...
