Stimuli responsive drug delivery systems have attracted considerable attention due to their ability to deliver drugs on demand to special tissues and cells (e.g. cancer cells). In this paper, we fabricated a new kind of redox/pH dual stimuli-responsive biodegradable poly(methacrylic acid) (MAA) nanohydrogels crosslinked by N,N-bis(acryloyl)cystamine (BACy) through a facile reflux-precipitation polymerization...
Preparation and characterization of activated carbons from oil-palm stones by carbon dioxide activation were studied in this paper. These oil-palm stones are agricultural by-products from palm-oil mills in several tropical countries. Ultimate and proximate analyses, pycnometry, mercury porosimetry, surface area and porosimetry as well as transmission electron microscopy were carried out for evaluating...
