Abstract
Quantum dots (QDs) and nanoplatelets (NPLs) are two types of nanoparticles used as scaffolds for enzymes operating in enzymatic cascades. Combinations of QDs and NPLs were surprisingly found to operate synergistically to create a greater enhancement than either alone when operating as scaffolds for enzymatic cascade reactions. A process involves providing an enzymatic cascade including a cluster of nanoparticles including both QDs and NPLs and having a plurality of enzymes bound thereto, the enzymes configured as an enzymatic cascade, such that the product of a first enzyme is a substrate of a second enzyme; contacting the cascade cluster with a substrate of the first enzyme; and allowing a reaction to proceed so that each of the plurality of enzymes acts in succession to produce an end product. The enzymes are bound to the nanoparticles via metal affinity coordination between histidine tags on the enzymes and zinc-containing surfaces of the nanoparticles.

Abstract
A method for using a single-pixel camera to reconstruct images of objects obscured by fog or other dynamic scattering media. A pseudo-random phase or intensity pattern is imposed on illumination beams directed at a target. The beam with the imposed pattern forms a pseudo random pattern on the target. Information regarding the pattern imposed on each pulse is entered into a data processor/controller. The illumination beams with the pseudo random patterns are reflected off the target, collected by receiving optics and a bucket detector and converted into electronic signals fed into the data processor/controller. The data processor/controller applies a high-pass filter to remove slower signal variations produced by dynamic changes in the scattering medium over time. The filtered bucket values are then used together with their corresponding speckle patterns to generate the images using any appropriate reconstruction algorithm such as CGI or CSI.

Abstract
Described herein is a one-pot, four-enzyme cascade of enzymes, three bound to quantum dots with one enzyme free in solution, for the conversion in vitro of fumarate to 1,3-diaminopropane. The cascade operates via two distinctly different enzymatic channeling mechanisms which simultaneously function to increase the overall rate. The first three enzymes of the pathway (AspB->LysC->Asd) were able to engage in channeling in a nanoparticle displayed format, but addition of the last two enzymes to this pathway in this format (AspB->LysC->Asd->Dat->Ddc) did not result in complete channeling through the entire pathway to the final diaminopropane product. Surprisingly, replacement of the last two enzymes (Dat->Ddc) with a naturally occurring fused Dat-Ddc hybrid (Daba) provided for full channeling in this system (AspB->LysC->Asd->Daba).

Abstract
A method of preventing photodegradation of dyes and pigments used in textiles and paints by surrounding photosensitive molecules with metal clusters that can absorb the damaging ultraviolet photons before they reach and damage the photosensitive molecules. A photosensitive dye or pigment is incorporated into a metal organic framework, which provides a scaffold to offer protection from ultraviolet degradation either by preferentially absorbing the ultraviolet light or by reflecting it before it reaches the dye. Isolating the dyes inside of the metal organic framework also sharpens the spectral features of the dye molecules.

Abstract
Disclosed herein are systems and methods related to a capsule endoscopy, where a patient can swallow an ingestible capsule that records images of digestive tract, and a new in-body positioning system can precisely localize the capsule's position. Implementations include a new frequency-division multiplexing-based magnetic localization (FDMML) approach which leverages a higher frequency carrier in the low MHz range. The approach significantly reduces the reference excitation coil sizes and decreases the required excitation current by three orders of magnitude compared to prior work, making it practical for wearable systems.

A method for coating high-aspect-ratio (HAR) and high-surface-area (HSA) substrates via atomic layer deposition (ALD) wherein the temperature of the substrate is varied cyclically during the ALD process. An exemplary temperature schedule for each ALD cycle includes at least one predetermined lower temperature during a diffusion/reaction stage of the cycle, where the lower temperature prevents decomposition of the ALD precursors and further prevents other side reactions, and further includes at least one predetermined higher temperature during a purge stage of the cycle, where the higher temperature enables rapid purging of excess precursor and/or byproducts produced during the reaction stage of the cycle. The prevention of side reactions ensures that the ALD coating is uniform and has the desired composition with minimal impurities, and the rapid purging ensures reasonable total process time.

LIME predicted thermostabilizing mutations were tested in four sets of sequence-related single domain antibodies (sdAb) having binding activity against Staphylococcal Enterotoxin B, 12 sdAb in total. The mutations were restricted to the constant regions. Two sets of interacting residues were consistently predicted. The first set was in the core of three variants, A7D, with W37R or W37H; these were predicted to form a salt bridge. The second predicted set of, interacting residues was on the surface and created a network of hydrogen bonds involving P22T with S8T accompanied by Q6S. Six mutations were common to all four sets: Q6S, A7D, S8T, (R/Q/E)14R, S18R, and P22T.

Abstract
A method of thermally protecting a leading edge of a hypersonic system includes saturating an annular primary wick in contact with an evaporator and having a first pore size with a phase change material by means of an annularly-inward secondary wick having a second pore size and being coupled to a liquid line, the second pore size being larger than the first, where a first end of the secondary wick extends into a reservoir and a second end of the secondary wick extends into the evaporator, the second end of the secondary wick having a terminal end. The method includes terminating the liquid line inside of the evaporator, transferring thermal energy from the leading edge into the phase change material, raising the temperature of the phase change material to a phase-change temperature, changing phase of the phase change material, and carrying away heat from the leading edge.
