摘要： A structured material is provided that includes a substrate and a porous structured polymer layer disposed thereon. The porous structured polymer layer includes a plurality of voids, and has a high hemispherical reflectance a high a hemispherical thermal emittance. The structured material is thus particularly advantageous for cool-roof coatings, enabling surfaces coated by the material to stay cool, even under strong sunlight. The material can be produced via structuring of polymers in a mixture including a solvent and a non-solvent. Sequential evaporation of the solvent and the non-solvent provide a polymer layer with the plurality of voids.

摘要： This application describes Swept, Confocally-Aligned Planar Excitation (SCAPE) microscopy systems that incorporate a gradient index (GRIN) lens to relay images from their distal tip to their proximal tip so that 3D images of deep tissue can be captured, without undue loss of light. A zero working distance feature can be designed into the third objective to ensure that the light that exits the second objective in the SCAPE system is not lost. Alternatively, a tapered fiber bundle may be positioned between the second objective and the third objective in the SCAPE system to ensure that the light that exits the second objective is not lost. As yet another alternative, direct detection at the intermediate image plane without using a third objective can ensure that the light that exits the second objective in the SCAPE system is not lost.

摘要： Described herein are new methods for making lung bud organoids (LBOs) that have the capacity of developing into branching airways and alveolar structures that a least partially recapitulate human lung development from mammalian, preferably human, pluripotent stem cells including embryonic stem cells (ESCs) and induced pluripotent stem cells (IPSC), either by culturing branched LBO in a 3D matrix or by transplanting the LBO under the kidney capsule of immune deficient mice. Branched LBOs contain pulmonary endoderm and mesoderm compatible with pulmonary mesenchyme, and undergo branching morphogenesis. Also described are LBOs harboring certain mutations that induce a fibrotic phenotype, and methods of making same. The mutated (B)LBOs can be used for screening agents that may treat pulmonary fibrosis.

摘要： A copper concentrate such as chalcopyrite is contacted with an aqueous solution includes acids and a reducing agent, such as vanadium (II) ions, chromium (II) ions, or tungstozincic acid (H6ZnW12O40). The aqueous solution reduces the copper in the copper concentrate, which can then dissolve into the solution for recovery therefrom, or precipitate out of solution as copper compounds or elemental copper for recovery in as a solid phase product. The solid phase product can then be isolated, dissolved, and further electrowinned to recover a copper product from the copper concentrate. Oxidized reducing agent can be recovered in an electrochemical device with ferrous iron reactants. Hydrometallurgical routes to convert copper concentrates to copper are potentially less expensive and less polluting than current pyrometallurgical processing and an advantageous response to environmental and economic pressures for increased copper production.
