Patent number: 11925977Abstract: A method for preparing aluminum foam sandwich material by rotating friction extrusion and electromagnetic pulse hybrid process includes: step 1: preparing the filler; step 2: processing the filler to prepare a plurality of preforms; step 3: clamping and fixing the plurality of preforms to form a preform assembly; step 4: welding the panel on the surface of the preform assembly to form an non-foaming sandwich material; step 5: heating and foaming the non-foaming sandwich material through a foaming mold; step 6: insulating the foaming mold after completion of foaming; injecting cooling water into the foaming mold after completion of insulation to maintain pressure and shape, forming the aluminum foam sandwich material of the required shape. The aluminum foam sandwich material produced by this method has good interface bonding, no adverse interface reaction, high bending resistance, impact resistance, and excellent sound absorption and insulation properties.Type: GrantFiled: April 19, 2023Date of Patent: March 12, 2024Assignee: NANCHANG HANGKONG UNIVERSITYInventors: Jilin Xie, Jinyang Hu, Yuhua Chen, Timing Zhang, Limeng Yin, Xiao Song, Shanlin Wang, Jiaming Ni

Patent number: 8660831Abstract: An extension of COSMO-SAC to electrolytes (eCOSMO-SAC) combines the COSMO-SAC term for short range molecule-molecule, molecule-ion and ion-ion interactions with the extended symmetric Pitzer-Debye-Hückel term for long range ion-ion interactions. The extension recognizes that like-ion repulsion and local electroneutrality govern the surface segment contacts, and introduces a dual sigma profile concept for electrolyte systems. The eCOSMO-SAC formulation predicts activity coefficients of several representative electrolyte systems.Type: GrantFiled: October 12, 2011Date of Patent: February 25, 2014Assignee: Aspen Technology, Inc.Inventors: Shu Wang, Yuhua Song, Chau-Chyun Chen

Patent number: 8370076Abstract: In the present invention the NonRandom Two-Liquid segment activity coefficient model system of the parent application is extended for computation of ionic activity coefficients and solubilities of electrolytes, organic and inorganic, in common solvents and solvent mixtures. The invention method and system may be applied to the chemical and/or pharmaceutical design process. In addition to the three types of molecular parameters defined for organic nonelectrolytes, i.e., hydrophobicity X, polarity Y, and hydrophilicity Z, an electrolyte parameter, E, is introduced to characterize both local and long-range ion-ion and ion-molecule interactions attributed to ionized segments of electrolytes. Successful representations of mean ionic activity coefficients and solubilities of electrolytes, inorganic and organic, in aqueous and nonaqueous solvents are presented.Type: GrantFiled: August 19, 2010Date of Patent: February 5, 2013Assignee: Aspen Technology, Inc.Inventors: Chau-Chyun Chen, Yuhua Song

Patent number: 8346525Abstract: Included are methods for modeling at least one physical property of a mixture of at least two chemical species. One or more chemical species of the mixture are approximated or represented by at least one conceptual segment. The conceptual segments are then used to compute at least one physical property of the mixture. An analysis of the computed physical properties forms a model of at least one physical property of the mixture. Also included are computer program products and computer systems for implementing the modeling methods.Type: GrantFiled: January 11, 2010Date of Patent: January 1, 2013Assignee: Aspen Technology, Inc.Inventors: Chau-Chyun Chen, Yuhua Song
