Abstract: Polymer composites are provided, and more particularly, polymer composites of ground date pits disposed in a polymer matrix. The composites can be formed by a process of preparing reinforced polymer composites having a fibril melt fracture surface, including blending a mixture of date pit particulate with a thermoplastic polymer; melting the mixture; and forcing the melt through a die to produce the polymer composite having a fibril containing surface.

Abstract: A 3D structure of the graphite-titanium-nanocomposite complex and a method of preparing the graphite-titanium-nanocomposite complex are disclosed. The Graphite-titanium-nanocomposite complex includes a metal core associated with the two phases, amine functionalized graphite, and amine functionalized titanium. The method of preparation includes amine functionalizing of graphite and titanium with coupling agents to produce amine functionalized titanium and graphite, further mixing with a metal ion solution for synthesizing an ion complex. Trisodium citrate solution and sodium borohydride solution is added to the ion complex to prepare a 3D structure of the graphite-titanium-nanocomposite complex, employed as a catalyst.

Abstract: The invention provides a method and system for dynamically generating a hint to recall a password for a user account of a user. The method for dynamically generating the hint to recall the password for the user account of the user includes the steps of receiving the password for the user account while the user inputs the password field of a login page. The password comprises a plurality of characters. The method, then, converts the password from the plain text to a hash value using a hash function. Thereafter, the method performs a modulo operation on the hash value to obtain an index pointing an object within an object library associated with the user. The method, then, displays, the object as the hint. The hint enables the user to create a mental association between the password and the object for the user account.

Abstract: The invention provides a method and system for generating a message authentication code (MAC) for authenticating a message and for verifying the integrity and authenticity of the message. The method for generating the MAC for authenticating the message includes the step of compressing the message to generate a fixed-size residue of the message. The fixed-size residue of the message is computed from the message modulo a divisor. The method, then, multiplies the fixed-size residue of the message by an authentication key. Thereafter, the method computes an authentication tag for the message by encrypting the fixed-size residue of the message utilizing a semantically secure encryption algorithm. The method, then, transmits both the message and the authentication tag of the message from a sender computing device to a receiver computing device where the method verifies the integrity and authenticity of the message using the authentication key.

Abstract: A separation medium consisting of a cyclodextrin metal-organic framework (CD-MOF) for separating aromatic compounds and methods of preparing the same are presented. Bottom-up preparations include the following steps: (a) preparing a first mixture comprising a cyclodextrin, an alkali metal salt, water and an alcohol; (b) performing one of the following two steps: (i) stirring the first mixture; or (ii) adding an amount of a surfactant to the first mixture to form a second mixture; and (c) crystallizing the CD-MOF from the first mixture or the second mixture. Top-down preparations include the following steps: (a) preparing a first mixture comprising the cyclodextrin, an alkali metal salt, water and an alcohol; (b) crystallizing the CD-MOF from the first mixture; and (c) optionally performing particle size reduction of the crystallized CD-MOF. The CD-MOFs are amenable for use in methods for separating alkylaromatic and haloaromatic compounds from a mixture of hydrocarbons.
