Hydrogels are networks of polymer chains that are swollen in water. These gels can protect vulnerable objects (e.g., an egg or a fruit) if wrapped there around. Gels are constructed by either physical cross-linking (e.g., gelatin) or chemical cross-linking (e.g., acrylamide). The addition of starch granules to the above gels greatly enhances their protective abilities. When a load strikes a gelatin gel containing 20% starch, the peak impact force is reduced by 25% when compared to a bare gel without the starch. Correspondingly, the coefficient of restitution (COR) is also lowered by the presence of starch (e.g., a ball bounces less on a starch-bearing gel). The impact-absorbing effects of starch granules are correlated to their ability to shear-thicken water. When starch granules are gelatinized by heat, they no longer give rise to shear-thickening, and in turn, their protective ability in a gel is also eliminated.

REVERSIBLE ELECTROADHESION OF HYDROGELS TO ANIMAL TISSUES FOR SUTURELESS REPAIR OF CUTS OR TEARS
Electroadhesion, adhesion induced by an electric field, occurs between non-sticky cationic and anionic hydrogels. When gel and tissue are placed under an electric field, the pair strongly adhere, and the adhesion persists indefinitely thereafter. Applying a direct current (DC) field with reversed polarity elimi-nates the adhesion. The use of electroadhesion can seal cuts or tears in tissues or model anionic gels. In an example, electroadhesion works with the aorta, cornea, lung, and cartilage. In another example, electroadhered gel-patches provide a robust seal over openings in bovine aorta, and a gel sleeve is able to rejoin pieces of a severed gel tube.

After the spectrally-selective assembly, the Brillouin-scattered light from multiple points in the two-dimensional plane in the sample can be simultaneously detected by an electro-optical sensor. In some embodiments, the spectrally-selective assembly can be altered by changing a wavelength or polarization of the pumping light to allow acquisition of a Brillouin spectrum.

For example, methods and systems are described that include calculating initial radio frequency (RF) tones to be applied to multiple channels of the AOM; calculating, in response to an application of the initial RF tones, compensation RF tones to be added to the initial RF tones to at least partially correct for undesired crosstalk effects; and in response to the application of the initial RF tones and the compensation RF tones, calculating subsequent compensation RF tones to be added to the initial RF tones until the crosstalk effect in each of the multiple channels is below a threshold level.

IN-SITU CRYO-IMMUNE ENGINEERING FOR CANCER IMMUNOTHERAPY
Cancer immunotherapy deploys the host's immune system to recognize and attack cancerous tumors. However, the efficacy is greatly restricted by the immunosuppressive (i.e., immunologically cold) tumor microenvironment (TME). In-situ cryo-immune engineering (ICIE) strategy turns the TME from immunologically “cold” into “hot”. In particular, after the ICIE treatment, the ratio of the CD8+ cytotoxic T cells to the immunosuppressive regulatory T cells is increased in primary tumors and distant tumors without freezing. The ICIE treatment causes “frostbite” of tumor with cold-responsive nanoparticles that target cancer cells. This rapidly releases both anticancer drug(s) and PD-L1 silencing siRNA into the cytosol. This ICIE treatment leads to potent immunogenic cell death, which promotes maturation of dendritic cells and activation of CD8+ cytotoxic T cells and memory T cells. Collectively, ICIE enables an efficient and durable way to leverage the immune system for combating cancer and its metastasis.

Abstract
A system includes a quantum source and an optical device coupled to the quantum source. The quantum source is configured to emit an entangled photon. The optical device is configured to route the entangled photon to one or more outputs. In some aspects, the optical device can include a photonic integrated circuit (PIC). Advantageously the system can provide a routing scheme to route (e.g., passively, actively, dynamically, or a combination thereof) entangled photons from one or more quantum sources (e.g., trapped ion, single-photon source, quantum emitter, etc.) between different nodes, a quantum frequency conversion scheme to match near-infrared photons (750 nm to 1260 nm) and/or telecommunication photons (1260 nm to 1675 nm) entangled with photons from one or more quantum sources to an operating wavelength of the optical device (e.g., PIC), programmable routing and entanglement distribution, and scalable long-distance quantum networks.
Provided are compositions and methods for treatment of snakebites. The compositions include a metalloproteinase inhibitor. The compositions can further include one or more antibodies or antigen fragments thereof that bind to components of snake venom. The compositions are administered to an individual who has been envonmated by a snake to thereby reduce damage caused by the envonmation.
A structure can comprise a substrate and a composite coating. The composite coating can be formed over a surface of the substrate. The composite coating can include one or more nanoparticles within an oxide matrix. The nanoparticles can be formed of a temperature-dependent Mott insulator having a phase transition temperature. At a temperature below the phase transition temperature, the composite coating can transmit light in a first wavelength range, and at a temperature above the phase transition temperature, the composite coating can block light in the first wavelength range. For example, the structure can be used as a smart 10 window to help regulate heating of building interiors due to solar radiation. The composite coating can be formed via a short-duration, high-temperature heating pulse, for example, at least 1500 K for less than 60 seconds.

Radiative cooling compositions, as well as precursors for forming such compositions, are disclosed. The compositions comprise solid particles of at least a first composition (e.g., Al2O3), which are bound by a suitable binder (matrix or framework). During the synthesis of these compositions from a precursor, solvent of a binder-forming liquid such as water glass may be evaporated, or otherwise glass (e.g., mixed oxide) particles in the precursor may be softened and/or melted, in either case providing a binder for the solid particles. The manipulation of composition porosity, impacting mechanical strength, as well as performance characteristics (reflectance and/or emissivity), is possible through the selection of types and amounts of components, such that a suitable combination of properties can be engineered without the need for polymers or other materials that may be detrimental in terms of cost and/or stability.
