Gas fluidization of nanoparticles
… experimental study on the gas fluidization of nanoparticles shows that most nanoparticles can be fluidized in the form of nanoparticle agglomerates. For those agglomerates (fluffy carbon black and very large agglomerates) that are difficult to fluidize, channeling always occurs. For those …

Nanoparticles at liquid interfaces
This thesis is concerned with the study of two phase systems stabilised by nanometre sized solid particles. The understanding of how modifying these particles at the oil(air)-water interface can change the properties of the bulk systems they stabilise is important for a number of industrial …

Nanocalorimetry of Bismuth Nanoparticles
Also included is the results of a finite element analysis and simulated melting of bismuth films on various kinds of sensors. Temperature distributions are found to be nonuniform for calorimetric sensors with Al metallizations, but much more uniform for Pt metallized sensors. The consequences of …

Polymers, Nanoparticles and Phospholipids
In addition, we find binding of charged nanoparticles to the outer surface of phospholipid liposomes produces particle-stabilized liposomes that repel one another and do not fuse. Subsequently, the volume fraction can be raised as high as ∼50%, reversibly, still without fusion. In studies of …

Nanoparticles Targeting at Inflammation Site
… pain, two classes of biodegradable polymeric nanoparticles—PEG-b-PCL and PLGA—were investigated for their distinct drug release kinetics. PEG-b-PCL enabled prolonged, near zero-order release, whereas PLGA exhibited a rapid burst release. These insights informed the development of a clinically …

Defining Delivery Pathways of Nanoparticles
The goal of nanomedicine is to use nanoparticles to carry drugs to specific target site in the body. For cancer nanomedicine, a recent meta-analysis showed that only 0.7% of the injected nanoparticles reach the tumour. To address this delivery inefficiency, it is important to examine each …
