Abstract: Provided herein are systems, devices, and methods for improved treatment of tissue, such as brain tissue. The improved treatment described herein can result in improved tissue penetration of various compounds and chemicals, such as stains and immunohistochemistry reagents. For example, provided herein is a pressurizing device that may include a chamber body having an opening in one of a top and a sidewall of the body, and may also include a chamber lid covering the opening and releasably coupled to the chamber body proximate the opening. The chamber lid and chamber body form an air-tight cavity. The pressurizing device may also have an inlet passing through one of the chamber body and the chamber lid and into the air-tight cavity. The device may also include a retainer coupled inside the air-tight cavity and configured to releasably couple to at least one tissue sample receptacles.

Abstract: A polymeric material is produced by atomizing into droplets a composition containing addition-polymerizable material and reacting the addition polymerizable material in the droplets to produce the particulate product. The polymeric product may be, for example, a powder coating composition.

Abstract: A discoloration of an aminosilane having a content of a free base is treated by adding an acid chloride to the aminosilane to obtain a mixture having a molar excess of acid chloride; neutralizing the molar excess of the acid chloride in one or more steps with a molar deficit of a base to obtain a mixture containing a salt; separating off the salt from; and irradiating the remaining aminosilane with UV-containing light.

Abstract: A method for activating photoreactive compounds by supporting sample vessels containing a photoreactive compound at a selected temperature and irradiating the sample vessels while holding the sample vessels at a fixed relationship with the irradiating source so as to uniformly irradiate the compound.

Abstract: A water treatment apparatus is provided in which the ozone generation and the water treatment may take place simultaneously. The ozone is generated from a continuous supply of air and/or oxygen at the surface of a running water by means of a high voltage electrode placed in the air or in oxygen at some distance above the water surface. The strong electric field between the high voltage electrode and the surface of the electrically grounded water stream generates a multitude of small Taylor cones at the surface of the water. Each Taylor cone goes into corona and in the process it generates the ozone. As the ozone is generated at the water surface, a substantial amount of ozone is immediately dissolved in water and the ozone that diffuses in the air continues to be in contact with the water surface. The undissolved ozone may be percolated through the same water for an additional primary or secondary ozonation.

Abstract: The present invention discloses an apparatus and method for producing microcrystal particles by irradiating pulse laser beam on raw material gas and causing the raw material gas to generate dielectric gas breakdown. The apparatus includes a laser oscillator for generating the pulsed laser beam, a reactor in which the raw material gas is activated and dissociated by irradiating the pulsed laser beam, and cohered to the microcrystal particles by generating luminescence, and a control device for controlling the laser oscillator to establish a pulse spacing of the pulse laser beam larger than a duration defined as a time during which the activated and dissociated raw material gas completes cohesion and turns into the microcrystal particles in the reactor.

Abstract: The invention relates to apparatus for performing chemical and physical pressure reactions on samples by the action of microwaves, having container inserts to receive the samples that are at least in part microwave-permeable and are arranged in a microwave-impermeable housing connected via at least one coupling opening to a microwave generator. To enable pressure reactions to be performed at higher pressures and more economically overall, it is proposed according to the invention that the housing include at least one pressure vessel (4) of high-pressure resistant material whose coupling opening (12) is microwave-permeable and closed in a high-pressure resistant manner, and that a single container insert is arranged in the pressure vessel (4) so as to fit closely against its inner surface.

Abstract: The invention is primarily a metallized chloroplast composition for use in a photosynthetic reaction. A catalytic metal is precipitated on a chloroplast membrane at the location where a catalyzed reduction reaction occurs. This metallized chloroplast is stabilized by depositing it on a support medium such as fiber so that it can be easily handled. A possible application of this invention is the splitting of water to form hydrogen and oxygen that can be used as a renewable energy source.

Abstract: Photochemical reactions are conducted using polymer beads arranged as a monolayer, e.g. floating on the surface of a moving body of water. The polymer bead is impregnated with a reactant, floated on the water or otherwise exposed as a monolayer in direct sunlight so as to expose the reactant to solar radiation, collected at a downstream location, treated to remove product from the polymer, and then the bead can be recycled. The process can be used to collect and store solar energy in chemical form, or for conducting photochemical synthesis to produce useful chemical products.
