Here in our discovery, we present an innovative strategy to solve the self-discharge issue and to increase the battery's charge capacity. Moreover, we present all the electro-analytical results within a static battery (non-flow), indicating a discovery that meets more challenging and complex standards. The invention's strategy is the use of porous cathodes with a large surface area and the integration and embedding of bromine-capturing materials within expanded nanocavities. Additionally, we demonstrate an ideal quantitative range of bromine-capturing materials that can be introduced into the cathode pores. Discovering the correct quantity for operation is critical—either addition or reduction of the quantity adversely affects the battery's capabilities and fails to achieve desired performance. Furthermore, the invention showcases the creation of organic phases within the aqueous medium inside the pores, depending on bromine-capturing material types, that maximize bromine capture and prevent side reactions that may affect cathode efficiency

The current research deals with the development of an innovative technology for the future food industry, by growing different types of microalgae in unique hydrogel capsules made of polyvinyl alcohol/polyvinyl pyrrolidone/alginate (PVA/PVP/A)). The macrocapsules will serve as a basis to produce cultured seafood. These algae-based macrocapsules will be used as food supplements rich in nutrients, and as food for humans and other animals such as fish, poultry, etc. In this work, these unique hydrogel macrocapsules were developed and their composition and structure were optimized, and the ability to grow algae in them was demonstrated. The technologies that currently exist for growing algae are based on growing in a medium, in plates, and artificially in reactors, encountering many difficulties stemming, among other things, from various bacterial and fungal infections. In addition, to ensure adequate growth, an increased amount of expensive growth medium is used. As part of the present work, an innovative and unique technology for growing algae was developed instead of the technologies that exist today. We introduce microalgae plus growth mediums into macrocapsules that have been uniquely developed by algae encapsulation processes during the preparation of the hydrogel macrocapsules. The confinement of the algae is done to provide them with a place to grow and to protect the algae cells from infections and harmful microorganisms. We also provide microalgae the conditions they need for their growth: light, temperature, and growth medium. The capsules may also contain fragrances, flavors and chosen color. The monitoring of the growth of the microalgae was carried out in two main ways: 1. Tracking the intensity of the color of the macrocapsules, which increases as the concentration of algae in the macrocapsules increasing, 2. Monitoring the concentration of chlorophyll (absorbance at 680 nm) which increases as the concentration of algae in the macrocapsules increasing. It was most clearly demonstrated that the growth of the microalgae entrapped in the macrocapsules is significantly faster than their growth in the conventional methods. The capsules could be used as a basis for various food products by combining them as a raw material or as "ink" for 3D printing. In growing algae with the proposed technology, there is a significant saving in water growing areas compared to the technologies that exist today. The proposed technology of enclosing the algae in capsules will reduce the cases of pollution and at the same time reduce the amount of expensive medium required to grow the cells. This will reduce the growing expenses and make it possible to create future food at a cheaper price. Also, we save on the growing costs of the stage of separating the algae from the water, which is an expensive stage that requires resources and consumes a lot of energy. Furthermore, the capsule shell itself is used as a protein substitute and edible. In addition, if necessary, the separation of the cultured algae from the hydrogel polymeric macrocapsules can easily be achieved by adding chelating metal ions such as EDTA or sodium citrate. in conclusion, the use of the aforementioned macrocapsules will enable a controlled and clean process in a configuration close to the final food product, resulting in significant cost savings.

In this research, nano/micro-particles and thin coatings on different polymeric films were prepared in order to impart disinfectant properties on the film’s surface. The particles and coatings are based on silane polymers containing urea functional groups. The coatings divided into 4 types that release different biocide chemicals: activated chlorine, hydrogen peroxide, essential oils and metallic ions. All types of coatings illustrated biocidal effects against microorganisms and decrease/prevent biofilm formation. Synergetic anti-microbial effects were achieved by combining different types of coatings. The following diagram describes the four types of coatings prepared in the present work. Similar nano/micro-particles were also prepared.

In the present work, we purpose to achieve cobalt-free high capacity cathode for Na-ion batteries using high entropy approach. High entropy approach comprises the mixing of more than five elements in a single phase which itself is a challenge as it involves interplay between different elements to get the desired properties. Here, Li is introduced in the composition to get high configurational entropy that offers Na vacant sites, hence stabilizes the crystal structure by entropy stabilization, accelerate the kinetics and improves the air stability. With the optimization in the composition of cathode, a reversible capacity of 109 mAh g-1 (2-4V) and 144 mAh g-1 (2-4.3V) is observed in first few cycles with a significant stability during prolong cycling. Further, insitu and exsitu diffraction studies during charging and discharging has revealed that the high entropy strategy is successful in overcoming the complex phase transition in O3 layered structure by suppressing the O3’ phase. The impressive outcomes of the present work strongly motivate to pursue high entropy approach in developing efficient cathode for Na-ion batteries.

The invention is a new device and method that enables a better interface between electrodes and patients’ (or other) neural tissue, such as the retina. The invention is based on high-density electrode array integrated with glutamatergic (or other) cells. Upon implantation of the device into the subretinal space of patients suffering from retinal degeneration (e.g.; age-related macular degeneration) the neurons synapse with the host retina. Activation of individual neurons by electric field elicits activation of the host retina with natural characteristics and restores vision at resolution and quality near normal vision.

It is shown that when approaching the percolation threshold of a superconductor-insulator metamaterial, the critical temperature Tc can be significantly increased up to near-room temperature. This is due to the appearance of a negative permittivity near criticality. This yields electrons to experience attraction instead of repulsion, which leads the formation of Cooper electron pairs and, consequently, to superconductivity. The negative permittivity is found theoretically in the metal-dielectric superconducting metamaterial using the symmetric self-consistent effective medium approximation (SEMA) together with the Drude model of metal conductivity in the quasistatic limit. This negative permittivity value is substituted into the formula for the critical temperature, derived by the well accepted Ginzburg-Kirzhnits-Pashitskii theory which describes superconductivity in terms of permittivity where the concept of epsilon-near-zero (ENZ) has been employed. All analytical evaluations are exact within the framework of SEMA. We also provide a qualitative physical explanation for this theoretical prediction.

This invention relates to a novel method for low-temperature epitaxial growth of high-quality aluminum nitride (AlN) thin films using plasma-enhanced atomic layer deposition (PEALD). The process enables the deposition of epitaxial AlN films on GaN substrates emplates at just 300 °C, without requiring additional in situ plasma treatments or post-deposition annealing, which are typically needed to enhance film crystallinity but may damage underlying structures. The resulting AlN films exhibit excellent crystalline quality—validated by X-ray diffraction and transmission electron microscopy—maintaining epitaxial alignment throughout thicknesses up to 70 nm. This simplified, low-thermal-budget process enables integration of III-nitride semiconductors with thermally sensitive platforms like silicon, thereby advancing the manufacturing of next-generation optoelectronic and high-power electronic devices.
