A “water free,” proton conducting membrane for use in a fuel cell is fabricated as a highly conducting sheet of converted solid state organic amine salt, such as converted acid salt of triethylenediamine with two quaternized tertiary nitrogen atoms, combined with a nanoparticulate oxide and a stable binder combined with the converted solid state organic amine salt to form a polymeric electrolyt...
A novel and simple preparation of amine-modified γ-Fe2O3 nanoparticles is described. The presence of amine groups on the surface, instead of hydroxyl groups, will allow conjugation of biologically active molecules to the iron oxide nanoparticles without the need for a size increasing silica shell. Furthermore, the outer amine-layer increases the temperature of the γ-Fe2O3 to α-Fe2O3 structural ...
The title salt, C(16)H(24)N(4) (2+)·2C(7)H(7)O(3)S(-), crystallizes with the dication situated on an inversion center and the anion in a general position. The cation contains two ammonium and two free amine groups, and the observed conformation for the chain linking the benzene rings is different from that found in the free tetra-amine and in the fully protonated tetra-amine. All amine and ammo...
The study explores the yearnings of fisherfolks on their child’s education, hindrances, and factors that shape desire as parents. Field observations key informant interview among elder members fisherfolk communities surrounding Albay, Ragay, Asid Gulfs Bicol Region was utilized. revealed majority parents do not want children to continue fishing main source livelihood because potential risks, ha...
Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment and might result in a situation in which the process specification...
Amine compounds are believed to have acceptable results regarding their use as clay swelling inhibitor and corrosion inhibitor additives in drilling fluids. It is crucial to know the capability of amine compounds to enhance the thermal stability of drilling fluid; herein, a water-based fluid composed of biopolymer and other additives as the proper representatives of muds used in the pay zone se...
