The effects of silica nanoparticles on the properties of a commonly used Sylgard 184 polydimethylsiloxane (PDMS) in microfluidics were systemically studied. Two kinds of silica nanoparticles, A380 fumed silica nanoparticles and MCM-41 mesoporous silica nanoparticles, were individually doped into PDMS, and the properties of PDMS with these two different silica nanoparticles were separately teste...
In this study, chemical transformations of benzyl ester of О-(phenyl-2-acetamido-2,3-dideoxy-1-thio-β-d-glucopyranoside-3-yl)-d-lactoyl-l-alanyl-d-isoglutamine (SPhMDPOBn) on the fumed silica surface were examined, and the surface complex structure was characterized by temperature-programmed desorption mass spectrometry (TPD-MS), infrared spectroscopy (FTIR) and electrospray ion trap mass spect...
Abstract This study describes the development of a fog collector material for harvesting. Polypropylene (PP) doped with fumed silica (0–2%) was punctured at equal intervals and exposed to produced by humidifier. The amount water harvested each sample measured using an ultrasonic fogger. 1% most effective harvesting water, collected almost 19–20 times more than pure polypropylene. improvement is...
