LED lighting device includes LED light housing including hollow outer shell with planar mounting surface defined inner top side of accommodation chamber to face toward bottom opening and reflector cup mounted accommodation chamber and defining conical reflective surface therein and carrying lens at top center thereof with light exit surface of lens facing toward bottom opening of hollow outer shell, LED light-emitting module including circuit board mounted between planar mounting surface and lens, array of LEDs arranged front side of circuit board and control circuit with driver IC and capacitor thereof respectively arranged opposing front and back sides of circuit board for converting inputted AC power into stabilized DC power for driving LEDS. This structural design effectively increases available surface area of circuit board for circuit layout and related circuit layout insulation distance, allows installation of relatively larger amount of LEDs to increase overall brightness and makes reflector cup replaceable.

Substrates that exhibit antimicrobial and/or antifungal characteristics that persist through the useful life of the substrate, and more particularly textile substrates infused with or covalently bound to well-dispersed antimicrobial nanoparticles, such as silver and/or copper nanoparticles, which exhibit persistent and demonstrable bacteriocidal, bacteriostatic, fungicidal, fungistatic behavior through numerous wash cycles. Methods of manufacturing such substrates are also provided.

Methods and compositions for preparation of biological samples are disclosed. The methods include a prelysis step and a lysis step to make the cellular DNA available for further processing, amplification or analysis. The prelysis step includes the addition of a prelysis reagent to the cells. The prelysis reagent may include an enzyme to facilitate the disruption of the cells. The lysis step includes the addition of a lysis reagent to at least a portion of the prelysis reagent and cells.

An outdoor cooking apparatus having an indirect cooking chamber joined to and extending upward and rearward from a direct cooking chamber. A damper is operable to regulate fluid flow between the cooking chambers. Preferably, the cooking apparatus is operable for installation into an outdoor structure, and a flange is joined to at least one of the cooking chambers for engaging the structure and supporting the cooking chambers. Preferably, the indirect cooking chamber includes first and second doors that are rotatable about an approximately vertical axis for accessing an interior of the chamber, and a plurality of vertically spaced shelves are supported within the chamber. The shelves may be vertically adjustable. The direct cooking chamber preferably has a lid that is operable to lock when it is in an open position.

The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group.

An autoignition composition 14 is provided to manage the safe combustion of a primary gas generant composition 12. The autoignition composition 14 contains carboxylic acid and potassium chlorate. A method of managing the safe combustion of the primary gas generant composition 12 is also provided.

An improved cooling system provides cooling away from the surface of electrical and electronic components, by providing an available heat transfer surface area many times greater than that of a convoluted fin structure. The component to be cooled is in thermal contact with a cold plate evaporator device, and a graphite material is associated with the cold plate device. Refrigerant is circulated through the graphite material and the cold plate evaporator device, and the liquid refrigerant is at least partially evaporated by the heat generated by the component. Due to the open nature of the graphite material, the permeability of liquids and vapors is high, allowing for low pressure loss while still maintaining sufficient two phase flow to carry heat away from the electronics.

The present invention relates to 3D printable composition comprising a cross-linkable component, a non-cross-linkable polymer, and analyte sensor particles, and to a method of fabricating a scaffold for living cells, a scaffold for a living cell, and a kit of parts comprising components for performing the method to obtain the scaffold. The scaffold is useful for prolonged culture of living cells and allows monitoring a metabolite throughout the culture with high spatial resolution of the metabolite in the scaffold.

Damping valve having a damping valve body with at least one passage channel between two cover sides. An outlet opening of the passage channel leads into a cover-side annular channel which is limited by an outer annular valve support surface and by an inner annular valve support surface, the at least one annular valve support surface for at least one valve disk has a substantially constant width along the circumference, and the annular channel has a varying width along the circumference, and at least one valve support surface has a varying radius of curvature along the circumference.

A wipe system is provided that is comprised of an inner portion sealed within an outer portion before use. The inner portion, which is used for cleaning, for example, may be wetted or saturated with a disinfecting fluid. Removal of an edge associated with the outer portion allows it to be opened to expose the inner portion. The wipe remains interconnected to the outer portion during use so that an opposite side of the outer portion is the only surface in contact with the user's hand.
