A support member for a thermal processing chamber is described. The support member has a sol coating on at least one surface. The sol coating contains a material that blocks a desired wavelength or spectrum of radiation from being transmitted by the material of the support member. The sol coating may be a multi-layer structure that may include adhesion layers, transition layers, and cap layers, in addition to radiation-blocking layers.

A perovskite film, method of preparing thereof, and an optoelectronic device are provided. They are prepared by steps including preparing a mixture containing a first monomer and a second monomer which can be crosslinked in situ; performing an annealing process, and the first monomer and the second monomer are reacted in situ to form a first polymer which combines with the perovskite crystal grains formed by the perovskite precursor and is concentrated at a crystal grain boundary of the perovskite crystal grains to passivate the perovskite crystal grain defects, and then a perovskite film is formed by curing.

The present disclosure relates to disk separator plates that include a coating to increase the water contact angle of the exterior surface of the disk separator plate so as to decrease its wettability. The present disclosure also involves hard disk drives that include such a disk separator plate and related methods of forming such a coating.

Systems and methods of synthesizing nanoparticles on substrates using rapid, high temperature thermal shock. A method involves depositing micro-sized particles or salt precursors on a substrate, and applying a rapid, high temperature thermal pulse or shock to the micro-sized particles or the salt precursors and the substrate to cause the micro-sized particles or the salt precursors to become nanoparticles on the substrate. A system may include a rotatable member that receives a roll of a substrate sheet having micro-sized particles or salt precursors; a motor that rotates the rotatable member so as to unroll consecutive portions of the substrate sheet from the roll; and a thermal energy source that applies a short, high temperature thermal shock to consecutive portions of the substrate sheet that are unrolled from the roll by rotating the first rotatable member. Some systems and methods produce nanoparticles on existing substrate. The nanoparticles may be metallic, ceramic, inorganic, semiconductor, or compound nanoparticles. The substrate may be a carbon-based substrate, a conducting substrate, or a non-conducting substrate. The high temperature thermal shock process may be enabled by electrical Joule heating, microwave heating, thermal radiative heating, plasma heating, or laser heating.

A multilayer structure including a substrate and a first stack of a layer of SiO.sub.2 and a layer of material of the SiO.sub.xN.sub.yH.sub.z type positioned between the substrate and the layer of SiO.sub.2, in which the layer of SiO.sub.2 and the layer of material of the SiO.sub.xN.sub.yH.sub.z type have thicknesses (e.sub.B, e.sub.A) such that the thickness of the layer of SiO.sub.2 is less than or equal to 60 nm, the thickness of the layer of material of the SiO.sub.xN.sub.yH.sub.z type (e.sub.B) is more than twice the thickness (e.sub.A) of the layer of SiO.sub.2, and the sum of the thicknesses of the layer of SiO.sub.2 and of the layer of material of the SiO.sub.xN.sub.yH.sub.z type is between 100 nm and 500 nm, and in which z is strictly less than the ratio (x+y)/5, and advantageously z is strictly less than the ratio (x+y)/10.

Methods and systems for forming a layer from a fluid mixture on a web are provided. The system includes a fluid delivery apparatus for delivering the fluid mixture onto the web. The fluid delivery apparatus includes a cascade device and a chemical dispenser device. The system also includes a fluid stirring apparatus comprising at least one fan positioned over the web and configured to generate a flow pattern that stirs the fluid mixture on the web while the layer is being formed, without the at least one fan contacting the fluid mixture. The system further includes a fluid removal apparatus having a rinsing device and a suction device. The rinsing device is configured to dispense a rinsing fluid onto the web. The suction device is configured to remove by suction the rinsing fluid and a remaining portion of the fluid mixture remaining on the web after formation of the layer.

Crystallization of perovskite films was performed in supercritical carbon dioxide with and without organic co-solvents. Post deposition crystallization of the films was performed in a binary, single phase supercritical fluid at constant conditions (45° C., 1200 psi) but with varying organic co-solvent volume fractions up to 2%. The co-solvents can provide selective interactions with one or both of the perovskite precursor compounds resulting in different film morphologies ranging from uniform films containing large grains to films exhibiting large cubic or hexagonal crystals or preferential crystallographic orientations. The use of supercritical fluids to enhance or tune crystallization in solid-state thin films could have broad applications toward the realization of high efficiency photovoltaic devices.

Methods for forming carbon-based lubricious and/or wear-protective films in situ on the surface of steel alloys are provided. The methods use chromium-containing steel alloys, molybdenum-containing steel alloys, and steel alloys that contain both copper and nickel. When such alloys are subjected to a rubbing motion in the presence of a hydrocarbon fluid, the chromium, molybdenum, copper, and nickel in the steel alloy catalyzes the formation of solid carbon-containing films that reduce the friction, wear, or both of the contacting surfaces.
