The functional group comprises primary amine, carboxylic acid, lactam ring, polyamide polymer chain or group used to attach a similar functional group.

Provided are a halloysite powder and a method for producing the halloysite powder. The halloysite powder contains granules in which halloysite including halloysite nanotubes is aggregated. The granules have first pores derived from the tube holes in the halloysite nanotubes and second pores that are different from the first pores.

The present invention provides for an ice-nucleating particle for cloud seeding and other applications, which can initiate ice nucleation at a temperature of−8° C. Further, the ice nucleation particle number increased continuously and rapidly with the reducing of temperature. The ice nucleating particle in the present invention is a nanostructured porous composite of 3-dimensional reduced graphene oxide and silica dioxide nanoparticles (PrGO-SN). The present invention also provides for a process for synthesizing the PrGO-SN.

The present invention provides an energy storage device comprising a cathode region or other element. The device has a major active region comprising a plurality of first active regions spatially disposed within the cathode region. The major active region expands or contracts from a first volume to a second volume during a period of a charge and discharge. The device has a catholyte material spatially confined within a spatial region of the cathode region and spatially disposed within spatial regions not occupied by the first active regions. In an example, the catholyte material comprises a lithium, germanium, phosphorous, and sulfur (“LGPS”) containing material configured in a polycrystalline state. The device has an oxygen species configured within the LGPS containing material, the oxygen species having a ratio to the sulfur species of 1:2 and less to form a LGPSO material. The device has a protective material formed overlying exposed regions of the cathode material to substantially maintain the sulfur species within the catholyte material. Also included is a novel dopant configuration of the Li.sub.aMP.sub.bS.sub.c (LMPS) [M=Si,Ge, and/or Sn] containing material.

A process for refining crude molten silicon. The process includes oxidatively refining the crude molten silicon in the production of technical silicon. The crude molten silicon is admixed during the refining with a particulate mediator which has a minimum amount of metallic silicon of 8% by mass and also at least one or more of the elements H, C, O, F, Cl, Ca, Fe and Al. The particulate mediator is described by a characteristic number K which has a value of 0.03 to 6 mm.sup.−1 and is calculated using the formula

[00001]$K=\frac{6.Math.\left(1-{\mathrm{.Math.}}_{m,M}\right)}{d_{50,M}}$

where d.sub.50,M is the particle size (diameter) at 50% of the mass undersize of the grading curve of the particulate mediator [mm] and the ε.sub.m,M is the mean effective porosity of the particulate mediator.
