The innovation described here consists of synthesizing in a one-step process a self-standing electrode with single-atom catalysts (SACs) supported on a nanocarbon matrix that will outperform the established standards at a much cheaper cost for most electrocatalytic reactions. The scientific breakthrough supporting this research is based on the simultaneous delamination and doping of a thin film stack using chemical vapor deposition (CVD).

An electrochemical reactor that works in asymmetric method using flow electrodes to produce low cost green hydrogen gas. The electrochemical cell produces hydrogen using faradaic reaction for hydrogen evolution and capacitance electrostatic adsorption instead of oxygen evolution. Based on our Nofar scholar research, we developed and improved the device that is based on the described patent named:"METHOD AND APPARATUS FOR HYDROGEN PRODUCTION BY ELECTROLYSIS". Instead of using a static electrodes for the capacitance behavior we use flow electrodes that allows the regeneration of the electrodes outside the reactor in a different cell; hence, we do not require to pause the evolution of hydrogen for electrode regeneration and we need less electrodes that lower the cost of the electrochemical reactor.

Brought herein a novel system for periodic capture and release of CO2 from air using asymmetric configuration electrochemical cells. The capture and release mechanism are based on the "pH swing" principle in which CO2 is efficiently being absorbed into alkaline solution and being released when the solution becomes acidic. Adjustment of the pH of the solution is controlled by passing current through a special asymmetric electrochemical reactor where the solution passes through the reactor. Absorption of CO2 from the air or exhaust gas ("flue gas") is facilitated by passing the solution and CO2 through ordinary absorption column (or tower).

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.

The present invention describes the synthesis of polyvinyl alcohol/polyvinyl pyrrolidone (PVA/PVP) hydrogels containing water soluble and insoluble functional active materials, e.g., fungicides, fertilizers, essential oils, oxidants, metal ions, drugs, dyes, etc.) for different applications in agriculture, environment, cosmetics, and medicine. For this purpose, two methods have been used, direct and a swelling method. In the direct method, PVP was added to warm PVA aqueous solution, e.g., 90-95 °C. After a while the system was cooled down slowly to room temperature. During the cooling process and the PVA/PVP hydrogel formation appropriate concentration/s of water soluble, e.g. hydrogen peroxide, urea, methyl orange or trichloro acetic acid, or water insoluble materials, e.g., essential oils such as thymol or benzoyl peroxide was/were added. The water-soluble functional materials were dissolved in the aqueous phase of the hydrogel while the water insoluble in the organic (PVP and/or PVA) part. The formation of the PVA/PVP hydrogels (due to hydrogen bonds between PVP and PVA) leads to gradual increased viscosity which enable to mold the formed hydrogel to any desired shape. The mechanical properties of the final material were improved by repeated freezing-thawing cycles. If necessary, surface crosslinking of the hydrogel for controlled release is accomplished by reacting surface PVA (hydroxyl groups) with glutaraldehyde under acidic conditions via formation of polyacetal bonds.
