Abstract: Methods, apparatuses, and systems are provided for using laser ablation to manufacture nanoparticles. An example method includes steps of generating, by a laser beam generator, a laser beam, splitting, by a set of beam splitters, the laser beam into a plurality of derivative laser beams, and directing each derivative laser beam towards a plurality of targets. In this example method, the plurality of targets are submerged in corresponding synthesis solvents within corresponding synthesis chambers. Moreover, interaction of each derivative laser beam with its corresponding target releases nanoparticles into the corresponding synthesis solvent to create a nanoparticle solution including both the corresponding synthesis solvent and the released nanoparticles.

Abstract: A self-standing adhesive layer is configured to join a first adherend to a second adherend, with no additional adhesive. The adhesive layer includes a material that self-stands and is configured to adhere to the first and second adherends; a first surface of the material is opposite to a second surface of the material; a first area of the first surface has a first smoothness and/or morphology and/or adhesion properties; and a second area of the first surface has a second smoothness and/or morphology and/or adhesion properties, different from the first smoothness and/or morphology and/or adhesion properties. The first and second areas form a preset pattern on the first surface.

Abstract: A method for image reconstruction from plural copies, the method including receiving a series of measured projections pi of a target object h and associated background; iteratively reconstructing images hi(k) of the target object and images gi(k) of the background of the target object for each member i of the series of the measured projections pi over plural iterations k; and generating a final image of the target object h, based on the reconstructed images hi, when a set condition is met. The index i describes how many elements are in the series of projections pi, and iteration k indicates how many times the reconstruction of the image target is performed.

Abstract: A robotic vehicle for traversing surfaces comprises a chassis having a plurality of wheels mounted thereto. Two magnetic drive wheels are spaced apart in a lateral direction and rotate about a rotational axis while a stabilizing wheel is provided in front of or behind the two drive wheels. The drive wheels are configured to be driven independently, thereby driving and steering the vehicle along the surface. The vehicle also includes a sensor probe assembly that is supported by the chassis and configured to take measurements of the surface being traversed. In accordance with a salient aspect, the vehicle includes a probe normalization mechanism that is configured to determine the surface curvature and adjust the orientation of the probe transducer as a function of the curvature of the surface, thereby maintaining the probe at the preferred inspection angle irrespective of changes in the surface curvature with vehicle movement.

Abstract: A method for growing a transition metal dichalcogenide layer involves arranging a substrate having a first transition metal contained pad is arranged in a chemical vapor deposition chamber. A chalcogen contained precursor is arranged upstream of the substrate in the chemical vapor deposition chamber. The chemical vapor deposition chamber is heated for a period of time during which a transition metal dichalcogenides layer, containing transition metal from the first transition metal contained pad and chalcogen from the chalcogen contained precursor, is formed in an area adjacent to the first transition metal contained pad.

Abstract: Embodiments of the present disclosure describe diapocarotenoid plant growth regulators represented by formula (I): R-A-R (I) or a precursor, salt, solvate, stereoisomer or polymorph thereof; wherein R is a monovalent carbonyl moiety selected from the group consisting of aldehydes, ethers, diethers, carboxylic acids, alcohols, and ester carboxylates and A is a bivalent polyene represented by the bivalent moiety —(CRa═CRb)x—, wherein x is the number of double bonds in polyene moiety A, and Ra and Rb are, independently, hydrogen, a hydrocarbon, or an alkoxy group, and composition of the diapocarotenoid plant growth regulators in an agronomically acceptable carrier. Methods of regulating plant growth including promoting root development, increasing nutrient uptake, enhancing resistance to abiotic stress factors, invigorating plant growth, increasing plant yield, and increasing plant biomass by applying at least one diapocarotenoid plant growth regulator to a seed, plant propagation material, plant or plant growth medium are also described.
