A model to evaluate acquisition price and quantity of used products for remanufacturing
(
Elsevier
, 2012 , Article)
In this paper, an analytical model is proposed to evaluate optimal acquisition price and quantity policy based on the quality of returned used products that are subsequently used for remanufacturing. The model is developed ...
Nanofeatures of resorcinol-formaldehyde carbon microspheres
(
Elsevier
, 2012 , Article)
Resorcinol-formaldehyde activated carbon xerogels were synthesized at certain conditions, and their morphology was studied experimentally to examine their detailed nature on the nanoscale level, which has not been reported ...
Collective osmotic shock in ordered materials
(
Nature Publishing Group
, 2012 , Article)
Osmotic shock in a vesicle or cell is the stress build-up and subsequent rupture of the phospholipid membrane that occurs when a relatively high concentration of salt is unable to cross the membrane and instead an inflow ...
Zeolitic imidazolate framework (ZIF-8) based polymer nanocomposite membranes for gas separation
(
Royal Society of Chemistry
, 2012 , Article)
As synthesised ZIF-8 nanoparticles (size ∼ 60 nm and specific surface area ∼ 1300–1600 m2 g−1) were directly incorporated into a model polymer matrix (Matrimid® 5218) by solution mixing. This produces flexible transparent ...

CO 2 adsorption studies on Prussian blue analogues
(
Elsevier Inc.
, 2012 , Article)
Carbon dioxide (CO2) adsorption capacities of several Prussian blue (PB) analogues have been studied using the state-of-the-art Rubotherm® sorption apparatus to obtain adsorption and desorption isotherms of these compounds ...
High capacity carbon dioxide adsorption by inexpensive covalent organic polymers
(
Royal Society of Chemistry
, 2012 , Article)
Efficient CO2 scrubbing without a significant energy penalty remains an outstanding challenge for the fossil fuel-burning industry where aqueous amine solutions are still widely used. Porous materials have long been evaluated ...
