The particle size ranges from 10 to 100 nm, which enhances their penetration through cellular membranes making microemulsions suitable as drug carriers. Due to the presence of polar and non polar components in ME’s, they are very good solubilizing agents. Their properties can be adjusted to ...
For the first time, a model has been developed to characterize particle bodies in a variety of jamming situations and sizes.When several balls are crammed into a box, especially if they are all the same size, the amount of empty space between them can be seen. Due to the presence of ...
Fig. 2), we find t(U) ≈ 8 ns for the voltage U at which the pore becomes free of co-ions. In this sum, the waiting time Δtn increased from Δt0 ≈ 0.18 ns after the first step to Δt7 ≈ 3.6 ns after the last step, a more than ten-fold increase due ...
How a scanning electron microscope (SEM) works A scanning electron microscope scans a beam of electrons over a specimen to produce a magnified image of an object. That's completely different from a TEM, where the beam of electrons goes right through the specimen. Electrons are fired into the...
The method used to calibrate the automatic particle counter should also be considered, especially if it cannot distinguish bubbles from particles. This rarely will be presented in any oil analysis report, so you will need to contact your lab or equipment manufacturer to find out which ISO calibrat...
Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
Full size table Since the robotic setting is somewhat different from a traditional operating room setting, many current image guidance modalities have to be specifically adapted. However, since most robotic platforms harbor a plural of highly maneuverable instruments, this does open up many new advanta...

Fungi have been companions of mankind for millennia. Mushrooms inspired our eating culture, and yeasts and filamentous fungi were developed into highly efficient cell factories during the last 100 years to produce many products utilized in different indu
Full size image The RPE tight junctions form the outer retinal-blood barrier and prevent diffusion of large molecules from the choroid to the retina. Therefore, cholesterol from lipoprotein particles (LPPs) in the choroidal (systemic) circulation is delivered to the RPE via different receptors (LDL...
