Atomic vibrations, in the form of phonons, are foundational describing thermal behavior materials. The possible frequencies phonons materials governed by complex bonding between atoms, which is physically represented a spring-mass model that can account for interactions (spring forces) atoms (masses). lowest-order, harmonic , approximation only considers linear forces and thought incapable expl...

The main objective of this search was to prepare novel soluble polyureas with improved thermal stability. Accordingly, a new types of polyureas was prepared through the polycondensation reaction of a prepared diamine containing ether, keto, and naphthyl groups with 4,4’-diphenylmethan diisocyanate (MDI), toluene-2,4-diisocyanate (TDI), and isophorone diisocyanate (IPDI) in N-methyl-2-pyrrol...

Commercial manufacturing of dairy products involves the addition ingredients (such as nonfat dry milk and protein concentrates) well non-dairy additives gums, stabilizers, emulsifiers, texture modifiers) to get best product appearance, maintain quality, extend shelf-life. Though these are not harmful, consumers do prefer them in food formulations. Therefore, industry is working on improving inh...
