Abstract: Biomineralization—the synthesis of inorganic materials using proteins—has recently gained interest as a low cost, green route for the production of metal chalcogenide semiconductor nanocrystals. Typical biomineralization approaches rely on proteins or biomolecules identified from organisms which possess a native biomineralization response. Disclosed herein is an alternative biomineralization approach for synthesizing metal chalcogenide nanocrystals which uses an artificially designed de novo protein. De novo proteins are non-natural proteins, allowing for facile modification of the protein through the tuning of amino acids within the sequence. This de novo protein was employed to produce size-controlled populations of semiconductor nanocrystals, with properties consistent with those produced using traditional routes.

Abstract: The present invention relates, in certain embodiments, to a fusion protein comprising a DEEP fusion tag and a target protein (e.g., protein of interest). In various other embodiments, the invention provides methods of producing a fusion protein comprising a DEEP fusion tag and a target protein, constructs comprising a nucleotide sequence encoding a DEEP fusion tag and a cloning site for introducing a nucleotide sequence encoding a target protein, and kits comprising such DNA constructs.

Abstract: A busbar assembly includes at least two busbars each having a current flow direction and a cross-sectional area with regard to the current flow direction, the cross-sectional area having opposing first and second long sides and two opposing small sides, each busbar having a through-hole extending from the first long side to the second long side. An insulating body surrounding the long sides and the small sides of each busbar along a part of the current flow direction and forming an opening for each busbar on the first long side so as to allow access to the through-hole. The insulating body forms a collar extending away from the first long side and surrounding the openings.

Abstract: Cooling structure including a fluid distribution layer with a first opening and a second opening for a cooling fluid, which are arranged at opposite sides of the fluid distribution layer. Also included is an elongated inner area, in which the first opening is positioned, an elongated outer area, in which the second opening is positioned, with two side arms, which partly surround the inner area, and a barrier separating the inner area and the outer area, The width of the inner area decreases along a direction from the first opening to the second opening. In addition, an electric power converter and a vehicle are disclosed.

Abstract: A cooling structure including several layers and a network of local chambers distributed between the several layers stacked one on another according to a stacking direction. Each local chamber includes at least two apertures, of which at least one is in communication with a local chamber of another of the layers. Each local chamber includes one or several meander-like structures blocking any direct path in the local chamber between the two apertures.

Abstract: We have developed a high through-put screen capable of isolating inhibitors of polypeptide aggregation, such as Alzheimer's Disease polypeptide A? aggregation, or other disease state aggregating proteins, from amidst large libraries of candidate inhibitors. The screen uses a fusion of a polypeptide domain that self-aggregates, such as an A?42 domain characteristic of Alzheimer's disease plaques, to a reporter construct, such as Green Fluorescent Protein (GFP) or similar fluorescent protein. In the absence of inhibition, the rapid misfolding and aggregation of A?42 causes the entire fusion protein to misfold, thereby preventing fluorescence. Compounds that inhibit A?42 aggregation enable GFP to fold into its native structure, and can be identified by the resulting fluorescent signal.

Abstract: The present invention provides a quadrupole mass spectrometer and an ion filter for use in the quadrupole mass spectrometer. The ion filter includes a thin patterned layer including a two-dimensional array of poles forming one or more quadrupoles. The patterned layer design permits the use of very short poles and with a very dense spacing of the poles, so that the ion filter may be made very small. Also provided is a method for making the ion filter and the quadrupole mass spectrometer. The method involves forming the patterned layer of the ion filter in such a way that as the poles of the patterned layer are formed, they have the relative positioning and alignment for use in a final quadrupole mass spectrometer device.
