Mouse Eda (Ectodysplasin-A) ELISA Kit

Polyesteramide (PEA) based hot melt adhesive (HMA) was successfully designed containing a high content of renewable mass. The PEA HMA was synthesized based on dimer acid (DA), catechol, ethylenediamine (EDA), ricinoleic acid amide (RA amide) which was synthesized by using ricinoleic acid and diethanolamine. RA amide was reacted with dimer acid with a varying concentration of RA amide by 5%, 10%, 15% and 20% on a molar basis. Catechol was further added on the molar basis of 10%, 20%, and 30% as a partial replacement of ethylenediamine. The effect on the properties of the hot melt adhesive, such as mechanical properties: tensile strength, shore D hardness, elongation at break; thermal properties: glass transition temperature (Tg), melting temperature (Tm), heat of crystallization (Hc), crystallization temperature (Tc); adhesion properties: lap shear strength (LSS) and T-peel strength (TPS); rheological properties and degree of crystallinity was investigated. It was observed that the mechanical and thermal properties are increased with increasing concentration of RA amide and catechol. These HMA materials could hold potential for sustainability and high adhesive performance.

Carbon nanotubes could accumulate in organism and have a negative impact on the structure and function of the ecosystem when they were discharged into environment. Furthermore, it will affect the migration and fate of pollutants in the water body. The study is mainly to explore the adsorption behavior and mechanism of beta-blocker on multi-walled carbon nanotubes (MWCNTs). Propranolol (PRO) was selected as the representative of beta-blocker. The effects of different environmental factors such as pH, ionic strength and humic acid (HA) on the adsorption process were investigated. The adsorption results were characterized by Zeta potential. At the same time, the effects of different types of drugs on the adsorption process were explored and the possible adsorption mechanisms were analyzed. The experimental results showed that the adsorption behavior was significantly different under different pH conditions. pi-pi EDA interaction, hydrophobic interaction and hydrogen bonding were speculated to be the main adsorption mechanisms for PRO adsorption on MWCNTs.
