The recent emergence of micro-devices for vaccine delivery into upper layers of the skin holds potential for increased immune responses using physical means to target abundant immune cell populations. A challenge in doing this has been a limited understanding of

A universal photoelectrochemical (PEC) sensing platform was fabricated based on the composition of protoporphyrin IX (PPIX), tungsten trioxide (WO3) and reduced graphene oxide (rGO) on indium tin oxide (ITO) electrode for detecting cysteine in aqueous solution. The rGO layer was

Geometrical confinement effect in exfoliated sheets of layered materials leads to significant evolution of energy dispersion in mono- to few-layer thickness regime. Molybdenum disulfide (MoS(2)) was recently found to exhibit indirect-to-direct gap transition when the thickness is reduced to a

Hyperlipidemia enhances xanthine oxidase (XO) activity. XO is an important source of reactive oxygen species (ROS). Since ROS are thought to promote atherosclerosis, we hypothesized that XO is involved in the development of atherosclerosis. ApoE(-/-) mice were fed a Western-type

The construction of complex collimators with a high number of oblique pinholes is very labor intensive, expensive or is sometimes impossible with the current available techniques (drilling, milling or electric discharge machining). All these techniques are subtractive: one starts from

Permanent magnets are an essential technology for energy conversion. Motors and generators are used to convert energy between electrical and mechanical forms.

Questions

  1. I see this powder is < or equal to 10um, are the particles fairly close to 10um and standard in size or are they less than 10um but very varied in size?

    1 answer
    1. The particle size distribution of this material is not available. The average particle size is not determined on a lot to lot basis. Historical data indicates an average particle size range of 4.5 um to 9.8 um.
