Abstract: A method of manufacturing an electrochromic device is provided. The method includes providing a patterned arrangement of an electrically conductive material; and applying one or more layers of an electrochromic material to the patterned arrangement, wherein at least a portion of the electrochromic material is in electrical contact with the electrically conductive material. An electrochromic device and an electrochromic ink composition are also provided.

Abstract: Provided are objects constructed of compressed salt combinations including salt and at least one additive, wherein the at least one additive is selected to impart the object with resistance to water and humidity.

Abstract: Provided is a spectrally selective solar thermal coating, formed as a continuous uniform layer, combining a light-absorbing coating and an infrared (IR) reflecting layer positioned on top of the absorber coating. The coating is adapted for use in a plurality of applications, including amongst many control of stray light and absorptivity in thermosolar devices.

Abstract: Paint formulations having a high absorptivity with respect to solar radiation are disclosed herein. The disclosed paint formulations are also thermally and mechanically durable, thereby enabling the paint formulations to be used on components in solar thermal applications where exposure to high temperatures and environmental conditions may be an issue. The paint formulation can include an oxide-based pigment, an organic binder, one or more additives, an inorganic filler, and/or an organic solvent. The pigment can have a relatively high absorptivity with respect to light having a wavelength in the range from 250 nm to 3000 nm. Curing of the paint formulation can irreversibly convert the organic binder into an inorganic binder.

Abstract: A driver circuit for a digital signal transmitting bus includes a main switch. The main switch is connected to the bus, is controllable by the digital signal to be transmitted, and has one on-switching state in which it has maximum electrical conductivity, one off-switching state in which it has minimum electrical conductivity and at least one intermediate switching state with an electrical conductivity between the minimum and maximum conductivity. The digital signal has a first logic state and a second logic state, the first logic state controls the main switch to be in the on-switching state and the second logic state controls the main switch to be in the off-switching state. The main switch is in the intermediate switching state during switching from the on-switching state to the off-switching state and/or vice versa.

Abstract: A paint formulation can include an inorganic oxide-based pigment and an organic binder. The organic binder can be irreversibly converted to an inorganic binder upon curing of the paint formulation at a temperature greater than 200° C. The oxide-based pigment and/or the paint formulation itself can have an absorptivity of at least 80% with respect to the AM 1.5 spectrum. The paint formulation can also include at least one organic solvent, an inorganic filler, and/or at least one additive. Such paint formulations may be stable at high temperatures (e.g., 750° C.) and can be used as solar-radiation-absorbing heat-resistant coatings for components of a solar tower system.

Abstract: A disposable heating unit for use for heating the contents of a container, includes a first region containing a combination of at least two solid substances which undergo an exothermic chemical reaction which is not spontaneous at room temperature. Adjacent to the first region is a second region containing at least a first reagent. A storage cell is configured for releasing the liquid containing a second reagent into the second region. The first and second reagents undergo a spontaneous exothermic chemical reaction when brought into contact, thereby initiating the exothermic chemical reaction of the solid substances.

Abstract: A highly sensitive assay for the determination of Cr(VI), in the presence of Cr(III) and in the presence of other cations by cyclic voltammetry. The determination is carried out with a gold or gold-plated electrode with a self-assembled monolayer of a pyridine derivative of the kind of 4-(2-ethanethiol) pyridine. Determinations can be affected at extremly low levels of the order of 1 ppt (part per trillion 10.sup.12).

Abstract: A highly specific and sensitive electrode for the determination of ultra-low levels of mercury and an analytical system based on such electrode. The electrode is a glassy carbon electrode spin-coated with a monolayer of a highly sensitive reagent for the detection of mercury. The analytical method based on the use of this type of electrode is a voltammetric method. Concentrations of the order of as low as about 2.10.sup.-12 Moles mercury can be detected and measured. The reagent is 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo-[8.8.8]hexacosane.
