Abstract: Methods, compositions, systems and devices are provided in which zeolite particles, preferably of silicon and aluminum, are used as desiccants. In embodiments a plurality of zeolite particles are provided that are less than 1 mm in size. The particles may be arrayed such that at least some of the plurality of particles are spaced apart from each other and may be arrayed in rows and columns. Embodiments provide the particles are useful or removing water under ambient conditions and in removing water from air or material and in an embodiment removing water from plant material, such as harvested crop material, or where the dried air is contacted with plant material. Microwave radiation may be used to efficiently and in a cost effective manner dehydrate the rehydrated particles.

Abstract: Described are composite photonic materials that incorporate magnetic nanoparticles inside hollow or solvent-filled nano-scale or micro-scale shells and methods of making and using such composite photonic materials. When these photonic materials are present in a magnetic field, they exhibit a change in reflected, scattered, and/or transmitted light as compared to when the materials are not in the presence of the magnetic field. This results in the materials appearing to have a different color, such as when observed by the human eye or a light detecting device, such as a camera.

Abstract: A method for dynamic enhancement of chemical reactions by nanomaterials under hard X-ray irradiation. The nanomaterials were gold and platinum nanoparticles, and the chemical reaction employed was the hydroxylation of coumarin carboxylic acid. The reaction yield was enhanced 2000 times over that predicted on the basis of the absorption of X-rays only by the nanoparticles, and the enhancement was found for the first time to depend on the X-ray dose rate. The maximum turnover frequency was measured at 1 16×10-4 s-1 Gy-1. We call this process chemical enhancement, which is defined as the increased yield of a chemical reaction due to the chemical properties of the added materials. The chemical enhancement described here is believed to be ubiquitous and may significantly alter the outcome of chemical reactions under X-ray irradiation with the assistance of nanomaterials.

Abstract: A principle is established to show that nanoscale energy deposition in water by X-rays can be greatly enhanced via the geometry of nanostructures. The calculated results show that enhancement over background water can reach over 60 times for a single nanoshell made of gold. Other geometries and nanostructures are investigated, and it is found that a shell of gold nanoparticles can generate similar enhancement. The concepts of composition, matrix, and satellite effects are established and studied, all of which can further increase the enhancement of the effect of X-rays.
