The maximum dry density of sand-capsules mixtures decreased from 1.56 to 1.53, 1.48, and 1.46 kg/m3, respectively. As the density of capsules were smaller than silica sand, with a greater percentage of additions, the density of the sand-capsules mixture decreased. However, the density ...

The practical application of nanoparticles (NPs) as chemotherapeutic drug delivery systems is often hampered by issues such as poor circulation stability and targeting inefficiency. Here, we have utilized a simple approach to prepare biocompatible and bi

(1 mmol) and p-tolualdehyde (3 mmol) in toluene (15 mL) was heated at reflux by using a three-necked flask equipped with a Dean-Stark apparatus. The resulting residue was purified by column chromatography on neutral silica gel (hexane/EtOAc = 4 : 1) to give NBP in 76% yield (0.76...

The mobility of negatively charged PNDDS strongly depended on the amount and type of salt present in the aqueous media: Without any salt, such PNDDS demonstrated no adsorption on silica surfaces and high levels of mobility in sand columns. The presence of CaCl2 and CaSO4, even at low ionic ...
