Thermodynamic properties of three composite materials
3(hydroxymethyl)aminomethane is abbreviated as Tris, which can be used in many fields such as organic synthesis, new materials, biological buffers, and pharmaceutical excipients. The use of Tris in porous composite materials is one of the important applications and researches. This article briefly introduces its thermodynamic properties.
Tris(hydroxymethyl)aminomethane improves the thermal stability of composite materials
Tris composites improve energy distribution
Tris is used in porous composite materials to play an important role in energy distribution and improving utilization. Nowadays, energy shortage and energy waste are becoming more and more serious. In addition to the development of new energy sources, how to solve the problem of unequal distribution of energy in space and time has become the focus of research. Filling tris (Tris) into porous silica gel (SG) with a pore size in the range of 15-100 nm and porous glass (CPG) with a nominal pore size in the range of 12-100 nm, which can make these have excellent storage. Phase change materials with thermal properties are more widely used.
Thermohematological stability of Tris and its composites
Tris/silica gel and tris/porous glass composite materials can be shaped by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), differential scanning calorimeter (DSC) and other characterization methods. Characterization of appearance and heat storage performance. The phase transition temperature, phase transition enthalpy, and degree of subcooling of the composite heat storage material all change with the size change, that is, the "size effect". Usually composite materials have this phenomenon, but for composite materials with a single pore size, trihydroxyaminomethane exhibits a stable phase transition temperature and phase transition enthalpy during thermal cycling. Both the conventional trihydroxyaminomethane and the composite obtained by filling it in the porous medium have the same pattern in the characterization of its morphology and functional groups.
Performance of Tris(hydroxymethyl)aminomethane composite material
Solution immersion method is used to prepare composite materials with different pore diameters of silica particles and porous glass as the frame structure, and the Tris filling rate is not less than 80%; in the two types of composites, ΔT and ΔH are linearly related to the reciprocal of the pore diameter; the temperature rises and falls of the composite material Cycle several times (≥10), its phase transition temperature, enthalpy change and other cycle performance are stable.
In summary, we can know that both Tris itself and the Tris-filled composite material have the advantages of small size effect, stable thermodynamic properties, and stable performance in multiple cycles of heating and cooling. Desheng is a raw material manufacturer of Tris Hydroxymethylaminomethane, which can supply large quantities of industrial grade and reagent grade Tris raw materials.
MOPS buffer is an important biochemical reagent used to maintain the acid-base balance and ion environment of tissue samples, protecting cell structure and function. Widely used in cell culture, tissue fixation, and immunohistochemical staining to improve experimental accuracy and reliability. Understanding the characteristics and application principles of MOPS buffer is crucial for biomedical research.
