resistance to a huge variation of temperatures and pHs, an advantage against the most varied conditions required for enzymatic reactions, and the inhibitory action upon trypsin may put this inhibitor as a biopharmacological candidate. Considering that
nano-sorbents have proved to be especially effective because of their high specific surface areas, highly active surface sites, and the absence of internal diffusion resistance in the separation process [ 9 ]. Magnetic nanoparticles (MNPs) have
acid were obtained from Merck Company (Darmstadt, Germany). Ultrapure water (resistance >18 MΩ) was prepared by Milli-Q purification system (Bedford, USA). Figure 1. Chemical structure of panasenoside (A
sulfate (SDS) with purity of 97% was purchased from Macklin Biochemical Co., Ltd. (Shanghai, China). Ultrapure water with the specific resistances of 18.2 MΩ·cm was produced by a Milli-Q ultrapure water system (Millipore, Bedford, MA, USA) for aqueous
composed of uronic acid residues which are linked together by α -1, 4-glycosidic bonds [ 2 ]. The pectin is favored in formulations due to its resistance property against certain enzymes such as amylase and protease but a disadvantage of the early drug
[ 1 – 5 ]. The sieve-molecular properties, availability of strongly active surface sites, high resistance to acids and other useful properties of zeolites allow the use of them as catalysts in cracking, hydrocracking, isomerization and other processes
Introduction Advanced ceramic materials are used in variety industries, especially in optoelectronics, metallurgy, medicine, and space industry due to their high thermal resistance, hardness and other unique properties. The key
concreting in temperatures below zero, higher resistance for sulphate aggression or fast increase of strength are required. Moreover calcium aluminate cement may be a component of ready for use mixtures for special applications in building works, for example
]. Conventional, Earth-based analytical instruments have to face various requirements when applied in space: energy consumption, size and weight, temperature, and radiation resistance are pivotal parameters. A variety of analytical instruments are used on the ISS
resistance and thermo-oxidative stability [ 17 , 18 ]. The high reactivity of the oxirane ring of epoxides makes it possible to obtain a wide range of compounds or organic–inorganic hybrid polymers. Siloxanes are used for the modification of epoxy resins
