A radiation shielding material for shielding against gamma radiation includes neodymium-doped zirconia nanoparticles in a matrix. The neodymium doped zirconia nanoparticles have a tetragonal crystal structure and an average size between about 25 nm to about 35 nm. The nanoparticles have a neodymium content in the range of about 1.5 mol % to about 3 mol % based on the total molar content of the zirconia nanoparticles. A method for the synthesis of neodymium-doped zirconia nanoparticles is provided. The method includes controlled metamorphosis of zirconia from monoclinic to tetragonal phase which results in a multifunctional shielding material having durability and high radiation absorption efficiency.

A battery cell arrangement for a battery of a motor vehicle having a plurality of cylindrical battery cells, of which at least two battery cells are arranged as a pair of cells. One battery cell of the pair of cells is arranged in an axial direction behind the other battery cell of the cell pair such that a top region of the one battery cell faces a bottom region of the other battery cell. A contact element arranged between them produces an electrically conductive connection between the top region and the bottom region. A thermal insulation is arranged between the battery cells, and the insulation inhibits a heat transmission by heat radiation in the axial direction between the battery cells of the pair of cells.

Systems and methods for nuclear reactor direct drive of a cryocooler turbine. A nuclear thermal propulsion (NTP) system may have a nuclear reactor that heats a thermal working fluid for directly driving the turbine to power a cryogenic fluid management (CFM) system for keeping propellant at cryogenic temperatures. The features may be used on NTP rockets. The propellant may be liquid hydrogen.

A method of controlling a substrate etching process includes disposing a surface or a surface of a substrate adjacent to etching fluid to produce an etchant-substrate interface and placing an electromagnetic radiation emitter on a moveable positioner. The method includes focusing electromagnetic radiation from the electromagnetic radiation emitter to a portion of the etchant-substrate interface. The portion of the etchant-substrate interface has a surface area of not less than 0.05 squared micrometers and not greater than 80 squared millimeters. The method includes selectively heating the portion of the etchant-substrate interface and transmitting a monitoring beam through the substrate.

Disclosed are methods for minimizing x-ray scattering artifacts, the method comprising: contacting an object with an x-ray scattering mitigation material. The contacting can comprise coating the x-ray scattering material on the object, including spraying a solution of suspension of an x-ray scattering mitigation material onto the object or dry powder coating the object with a x- ray scattering mitigation material. Alternatively, the contacting can comprise immersing the object in a fluid comprising the x-ray scattering material. The fluid can be a gas, a liquid, or a gel. The disclosed x-ray scattering mitigation material can be optimized for mitigating Compton radiation scattering or for mitigating Rayleigh radiation scattering. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A power generation system and related method for repowering a fossil-fueled power plant using a carbon-free nuclear steam supply system (NSSS) which replaces the existing fossil plant steam generator which burns fossil fuel such as coal, oil, or natural gas. The existing fossil plant energy conversion system including the turbine-generator (turbogenerator) and auxiliary components of the Rankine cycle is retained. The NSSS may include a small modular reactor (SMR) unit comprising a reactor vessel with nuclear fuel core and steam generator which receives heated primary coolant from the reactor to produce main steam to operate the Rankine cycle. The main steam output by the SMR unit is compressed in a steam compressor to increase its pressure to a level necessary to operate the turbogenerator. The compressor may be operated via a portion of the main steam. An intercooler of the compressor may be used for main steam reheating.

A method includes, using a laser, thinning a target site in an iris of an eye by irradiating the target site with one or more first radiation-pulses. Subsequently to thinning the target site, a peak intensity of radiation beams emitted by the laser is increased and, subsequently to increasing the peak intensity, a hole is formed through the target site by, using the laser, irradiating the target site with one or more second radiation-pulses.

In a method of generating extreme ultraviolet (EUV) radiation in a semiconductor manufacturing system one or more streams of a gas is directed, through one or more gas outlets mounted over a rim of a collector mirror of an EUV radiation source, to generate a flow of the gas over a surface of the collector mirror. The one or more flow rates of the one or more streams of the gas are adjusted to reduce an amount of metal debris deposited on the surface of the collector mirror.
