Abstract: The present application relates to cellulose nanocrystals and other anionic carbohydrates and methods of preparation thereof. Specifically, in certain embodiments, the cellulose nanocrystals are modified using ion exchange technology to yield thermally stable or task-specific, dispersible cellulose nanocrystals.
Abstract: A natural liquid composition is provided for disinfectant, antibacterial or anticorrosion applications. The natural liquid composition is an electrospun solubilized composition of natural chitosan (CS) and an FDA approved polymer polyvinyl alcohol (PVA). Two fillers, citric acid (CA) and ascorbic acid (AA), added anti-corrosion property to the composite nanofiber solution without affecting the other properties (disinfectant and antibacterial) and have a final synergistic effect of all components together in a final solution form. Embodiment of the invention advances the art by providing a natural solution to overcome at least some of the problems with the currently used agents.

Abstract: A method of extraction of pure iron (III) oxide from bulk iron ore is provided that includes crushing and grinding, using a crushing machine, raw hematite ore, where a milled ore is formed, water-washing the milled ore by rinsing under continuous stirring conditions, dilute acid-washing the milled ore with diluted hydrochloric acid under continuous stirring conditions, immersing the dilute acid-washed milled ore in concentrated acid under the continuous stirring conditions, and applying heat, treating the heated and immersed milled ore with an alkali to form a precipitate, washing with water the precipitate to purify the precipitate, and drying the purified precipitate, and igniting the purified dry precipitate to extract a pure iron (III) oxide from a bulk iron ore.
Abstract: A multi-power-mode ultra-low-power address detector for Radio Frequency (RF) wakeup receivers is provided herein. The address detector is implemented when combined charging and wake-up of a device is required. The method includes a set of components to process a complex address waveform. This address includes a preamble composed of a pulse with a specific width, followed by a digital Pulse Width Modulation (PWM) modulated bit pattern.

Abstract: Aspects of this disclosure relate to a miniaturized digital radar system and method that can be fabricated on a Printed Circuit Board (PCB) and/or a chip, such as on a System-On-a-Chip (SOC). The digital radar system can operate at the S-band (e.g. in the range of 3 GHz). Advantageously, the S-band frequency range is less susceptible and/or not susceptible to clutter from precipitation and is well suited for long range surveillance applications. The small form factor of the miniaturized digital radar system on the PCB and/or the SOC can be implemented on small and/or low-observable platforms, such as on fixed or rotary wing unmanned aerial vehicles.
Abstract: Here we show that epigenetic control of Neuregulin-1 (NRG1) affects adipose differentiation of stem cells in vitro. Building on this finding, we established a model in which NRG1 is a white adipose tissue (WAT) specific regulator analogous to the role of NRG4 in black adipose tissue (BAT). In this light, NRG1 functions in a paracrine or autocrine manner to regulate formation of new adipocytes from stem populations, both in vitro and in vivo. In neurons, NRG1 has been shown already to play a similar role, promoting neuronal cell differentiation from progenitors in the vertebrate cortex and retina and even promoting neuronal differentiation in vitro. Similarly, in the heart, NRG1 promotes differentiation of cardiomyocytes from their stem cell progenitors both in vivo and in vitro and for this reason has been successfully tested in clinical trials for heart failure.
Abstract: A method for electroless deposition of aluminum or an aluminum alloy on a substrate surface. The method includes activating the surface of the substrate to be coated by applying a coating of a catalyst metal; preparing a mixture of urea ((NH2CONH2) and anhydrous aluminum chloride (AlCl3) wherein a molar ratio of AlCl3:(NH2CONH2 is greater than 1:1 to obtain a Lewis acid room temperature ionic liquid (RTIL) optionally containing an alloy metal salt; dissolving a hydride reducing agent in an aprotic anhydrous solvent to obtain a hydride solution; mixing the hydride solution and the AlCl3:(NH2CONH2 RTIL to obtain an electroless Al solution; exposing the activated surface of the substrate to the electroless Al solution; and removing the electroless Al solution from the substrate surface; wherein upon exposure of the activated substrate surface to the electroless Al solution, an Al or Al alloy coating is obtained on the activated substrate surface.
Abstract: The device measures glucose concentration in blood without any extraction of blood. The device is a non-invasive method for measuring glucose Radio Frequency and Antenna Circuits and Systems. The device is a wearable device that can non-invasively measure blood glucose levels in an instantaneous manner and continuous manner.
