Abstract
The subject of the invention is a hydrogen production device consisting of an evaporator (1) connected through a vapor channel with a sorbent bed (2) in which there is a heat exchanger (2a) to which from the source of cooling water a cooling water supply pipeline (14) is connected and from the heat exchanger (2a) cooling water discharge pipeline (13) is led. The heat exchanger (2a) is connected to the heat source (5) by means of the hot water supply pipeline (16) and the hot water discharge pipeline (17). The sorbent bed (2) is connected by means of a vapor channel (8) to the PEM electrolyser (3) from which the hydrogen discharge pipeline (21) and the oxygen discharge pipeline (20) are led. The method according to the invention consists in that in the first stage, sea water is sucked into the evaporator (1). After filling the evaporator, the seawater intake water valve (22) closes and the pump set (12) stops. In the second stage, the evaporator shut-off valve (7) opens and the sorbent bed (2) is cooled with sea water, whereby in the evaporator (1) clean water boils and is sucked in by the sorbent bed (2) as a result of the vacuum it generates. In the sorbent bed (2), the process of adsorption of vapor takes place until the sorbent bed (2) is saturated with vapor. In the third stage, the sorbent bed (2) is cut off from the evaporator (1) and the sorbent bed (2) is heated with hot water from a heat source (5) enabling desorption of water vapor from the sorbent bed (2) towards the anode of the PEM electrolyser (3). Pure hydrogen is produced by the reaction of water electrolysis.

Abstract
A non-transferred arc plasma torch with a method for the generation of plasma jet at high temperatures are disclosed. The main constituents of the torch assembly are a multiple-arc-producing cathode, a coolant distributing cell and an adjustable anode. The cathode comprises primary and secondary annular rods pointing towards the anode. The primary rod is pointing towards the center of the anode and is higher in length and diameter than the secondary ones. The secondary rods are similar in length and width. An internal coolant distribution cell was designed for internal cooling of the rods. The anode was configured to allow external adjustment of the gap between the electrodes. The electrodes were mounted into a jacketed cylindrical housing consisting an internal path within the jacket for efficient recycling of the coolant. The system is initiated by forming multiple arcs between the cathode and the anode leading to the ionization of the forming plasma gas that passed continuously through the torch. Thus, the power efficiency of the torch enhanced and the lifetime of the electrodes increased. Eventually, a thermal plasma jet exits the torch through the anode nozzle.

Abstract
The invention relates to a method for producing nanoparticles of zinc sulfide activated by silver and chlorine in an ecological furnace. The nanomaterial prepared according to the present invention is characterised in that it consists of spherical particles of zinc sulfide material having a nanostructure, the concentration of silver nitrate being 0.4 mg/g of zinc sulfide, giving efficiency and a luminescent glow. The luminescent glow of the silver-activated zinc sulfide was 67% of the luminescent glow of standard zinc sulfide material. The zinc sulfide prepared according to the present invention was also used to build a 610A-model radon cell. The efficiency of the new cell was 70% in comparison with the efficiency of a standard cell built using standard zinc sulfide material. The material prepared according to the invention has an excellent linear response to alpha particles with an energy of 5.48 million electronvolts, allowing the prepared material to be used in alpha-particle detectors and the measurement of radon gas concentration.

Abstract
A periodically-rippled patch antenna structure with metal coated trenches only along one in-plane direction or in two perpendicular in-plane directions on a dielectric substrate and ground plane and methods of fabricating the antenna radiating elements are provided. An optional layer of oxide or nitride can be placed between the substrate and metal layers as an insulation layer. This use of trenches allows for miniaturization of the patch antenna as well as dual-band degeneracy. When a square 1D rippled patch antenna is excited by a microstrip line connected along the ripples, the effective length is longer than with a line orthogonal to the ripples enabling dual mode degeneracy and antennas working at two distinct frequencies of operation.

Abstract
Methods for removing a material layer from a base substrate utilizing spalling in which mode III stress, i.e., the stress that is perpendicular to the fracture front created in the base substrate, during spalling is reduced. The substantial reduction of the mode III stress during spalling results in a spalling process in which the spalled material has less surface roughness at one of its' edges as compared to prior art spalling processes in which the mode III stress is present and competes with spalling.

Abstract
A convective method is employed to cool a solar concentrator device. The convective method employs formation of a vortex gas circulation inside an enclosure of the solar concentrator device, which is bounded by at least one light-path altering component, sidewalls, and a back panel. Optionally, a heat sink assembly can be provided within the enclosure. Internal convention through the vortex gas circulation transfers the heat generated at a photovoltaic cell to all surfaces of the solar concentrator device to facilitate radiative and/or convective cooling at the outside surfaces of the enclosure.

Abstract
Method to (i) introduce additional control into a material spalling process, thus improving both the crack initiation and propagation, and (ii) increase the range of selectable spalling depths are provided. In one embodiment, the method includes providing a stressor layer on a surface of a base substrate at a first temperature which is room temperature. Next, the base substrate including the stressor layer is brought to a second temperature which is less than room temperature. The base substrate is spalled at the second temperature to form a spalled material layer. Thereafter, the spalled material layer is returned to room temperature, i.e., the first temperature.
