摘要:The presented invention relates to a method of synthesis of carbon-supported platinum group metal or metal alloy nanoparticles, which comprises the following steps:n adsorbing on carbon support complexes of a platinum group metal with a urea complexing agent selected from a group comprising urea, urea derivative, a mixture of urea with at least one urea derivative, and a mixture of at least two urea derivatives; and reducing the complexes adsorbed on the carbon support to metal nanoparticles, forming a product of carbon-supported metal nanoparticles. nn The invention also provides the use of the carbon-supported platinum group metal or metal alloy nanoparticles obtained by the method of the invention as catalyst. n The present invention further relates to a method of adsorption of precursors of platinum group metals on the surface of a carbon support and use of complexes of platinum group metals with urea complexing agent for adsorption of platinum group metal precursors on carbon support.

标题 :Synthesis of transition metal hydroxides, oxides, and nanoparticles thereof
发明人：YAGHOOBNEJAD ASL HOOMAN

摘要:Techniques are disclosed for electrochemical synthesis of rechargeable battery cathode precursor materials using a porous carbon element. The porous carbon element acts as an air cathode to reduce oxygen. Reduced oxygen species may oxidize a transition metal anode, thereby facilitating a room temperature redox reaction with transition metals, including those that are generally resistant to corrosion, such as nickel. The transition metal reaction product(s) may be further processed into rechargeable battery cathode materials without also synthesizing hazardous waste products.

摘要:The present invention relates to a durable and multifunctional superhydrophobic coating composition and water based fabrication method of producing the durable and multifunctional superhydrophobic coating composition via chemical modification and functionalization of hydrophilic material by silanes under room temperature without any organic solvents. Synthesis of chemically modified cellulose nanofibers or clay in water forms excellent water repelling thin films upon coating over various substrates. The super hydrophobic materials are used as additive for paints, pigments, paper, varnish and, textile and used for various industrial applications such as construction of buildings and other super structures.

权利人:UNIV TEXAS TECH SYSTEM
摘要:Methods and systems for the electrochemical up-cycling of polymers. A slurry including a mixture of solid plastics flows through an electrochemical cell, which, through an applied potential, the plastics are converted into pure hydrogen, fuels, gasolines, and oxygen hydrogenated compounds that can be used for the synthesis of advanced materials and/or for easier biochemical/thermal degradation. Such methods and systems enables converting plastic waste to into fuels, chemicals, and high value products.

摘要:Site-specific modifications of proteins are desirable in biotechnological applications such as biopharmaceuticals, immunotherapy, vaccines, and are useful in chemical biology. Gluconoylation is a non-enzymatic, covalent, post-translational modification commonly observed on N-terminal His-Tags bearing proteins. We synthesized glucono-1,5-lactone derivatives, including azido variants for selective acylation. High yield acylation is achieved by simply mixing derivatives with target protein amidst diverse conditions of temperatures, aqueous buffers, excipients, or complex cell lysate.

摘要:A method of upcycling cathode active materials is provided. The method includes mixing two or more precursor materials at ambient temperature to form a first eutectic mixture. The method further includes mixing a cathode active material with the first eutectic mixture to form a second eutectic mixture. The method further includes subjecting the second eutectic mixture to a two-step calcination process. The two-step calcination process includes first calcining the second eutectic mixture at a first temperature for a first period of time to obtain an intermediate material and second, calcining the intermediate material at a second temperature for a second period of time to obtain an upcycled cathode active material. The second temperature is higher than the first temperature, and the upcycled cathode active material has a composition that is different than a composition of the cathode active material. A cathode active material formed by the method is also provided.
