International Classification:

C01G 49/08

US Classification:

252062560, 977900000

Abstract:

A process for preparing superparamagnetic transition metal nanoparticles by introducing into a gas stream a hydrocarbon and a transition metal carboxyl wherein the transition metal carbonyl is introduced downstream from the hydrocarbon; wherein at the point of introduction of the hydrocarbon the gas stream is in the form of a plasma, and wherein at the point of introduction of the transition metal carbonyl the gas stream is at a temperature of at least 1000 C.; followed by quenching to form carbon-coated transition metal nanoparticles; and wherein the gas stream consists essentially of at least one inert gas and hydrogen.

Abstract:

The present disclosure provides improved film based pharmaceutical products containing uniformly distributed drug or active agent particles (e.g., to achieve improved/excellent dissolution control including enhancing dissolution and bioavailability and/or product uniformity). More particularly, the present disclosure provides improved systems/methods for fabricating film based pharmaceutical products by utilizing higher surface modified micronized drug or active agent powders and film forming precursors and drying methods that accomplish improved/efficient drying and provide improved/excellent content uniformity of active pharmaceutical agents in the fabricated film based pharmaceutical products. In exemplary embodiments, the present disclosure provides for an easier means of directly incorporating dry micronized poorly water-soluble drugs or active agent particles (e.g., fenofibrate (“FNB”)) into films. The present disclosure demonstrates some advantages of direct incorporation of surface modified-micronized poorly water-soluble drug or active agent powders in film manufacturing.

Abstract:

In some embodiments, apparatuses and methods are provided herein useful to evaluate shipping packaging used at a distribution facility. Some embodiments provide a system to evaluate packaging, comprising: an evaluation control circuit and memory storing computer instructions executed by the control circuit causing the control circuit to: for each of multiple different distribution facilities: identify a fixed number of different shipping package sizes to be available; identify multiple different potential packaging combinations; evaluate each of the multiple potential packaging combinations for each of thousands of historic order shipments; obtain a utilization rate of each of the multiple packaging combinations; identify potential packaging combinations that satisfy a utilization threshold, and identify a predicted cost to acquire and utilize each of the identified potential packaging combinations; and select a first potential packaging combination satisfying the utilization threshold and having a lowest predicted utilization cost.
