摘要:A method for joining a ceramic or metal ceramic electrical heating element (1) to an electrical terminal (2) is disclosed, the heating element having been manufactured using micropyretic synthesis, the method for joining comprising the steps of preparing the electrical terminal by blending a combustible mixture and fashioning the mixture into a desired wet and uncombusted shape for the terminal, attaching the terminal to the element, drying the terminal portion of the terminal-element attachment and combusting the terminal portion of said terminal-element attachment by ignition at a temperature between about 150 °C and 1800 °C. An electrical terminal is disclosed, the terminal having been formed by micropyretic synthesis of a specific combustible composition. A heating element assembly for a heater is disclosed comprising a first and a second ceramic or metal ceramic electrical terminals, a plurality of ceramic or metal ceramic heating elements and a plurality of ceramic or metal ceramic coolers (3) which are used to connect said plurality of heating elements to each other.

摘要:The present invention is a method to produce a biodegradable thermally induced shape memory polymer (SMP) based on poly(ε-caprolactone) (PCL) and ethyl cellulose (EC). In this synthesis method, after grafting the PCL on the linear EC, the PCL chains are end-functionalized with furan and maleimide moieties. The cross-linked network is prepared via Diels-Alder (DA) reaction between furanyl and N-maleimidyl PCL chains. The synthesized SMP demonstrates excellent shape memory properties at near body temperature (41° C.). Moreover, the polymer network is recyclable and re-processable, since the DA reaction is thermally reversible. The SMP of the present invention is well suited for numerous applications, especially in medical devices, given their excellent shape memory performance, tunable materials properties, body temperature-based stimulus, biocompatibility, and potential for biodegradation and resorption.

摘要:RNAi nanoparticle conjugates and compositions thereof for management of cancer include an active ingredient, a polysaccharide, an RNAi silencer, and a coating agent. The conjugates are synthesized by encapsulating an active ingredient in a polysaccharide to obtain a nanoencapsulate that is fabricated into nanoparticles. The nanoencapsulate is immobilized with an RNAi silences to obtain a complex that is coated to form the conjugate. The conjugate is non-toxic, silences EphB4 gene, and is capable of targeted cancer therapeutics with enhanced permeation. The conjugate synergistically upregulates Wnt genes by RNAi and demonstrates tumor suppressive action of the active ingredient.

摘要:A product of acetoacetylated saccharide and the process of making such a product. The process is enzymatic where an enzyme is used as a catalyst for the reaction. The enzymatic process provides better yields and milder process conditions compared to other chemical synthesis process without any enzyme.
