Complementary studies on N* from e ⁺ e ⁻ , pp and pp̄ collisions

Abstract

Complementary to the conventional experimental studies on N * from πN and γ ( * ) N reactions, the e + e − , pp and pp collisions can give novel insights into these N * resonances. While the e + e − collisions through production and decay of vector charmonium ψ provide a nice isospin filter for a simultaneously study of N * , ∆ * , Λ * , Σ * and Ξ * , the pp collisions should be the best place for producing those ∆ * ++ with large coupling to ρ + p though pp → n∆ * ++ reaction, and the pp collisions should be the best place for looking for those N * with large coupling to σN .

Controlled Grafting of S-Naproxen Imprinted Layer on PVDF Microporous Membrane by ATRP

“…Nowadays, surface functionalization of matrix materials with a controllable imprinting polymer layer is attracting attention because the polymer layer coating improves the adsorption and recognition efficiency to the targets. The choice of the matrix ranges from silica materials [7] and carbon filter [8] to metals such as gold and aluminium as micro gravimetric quartz crystal microbalances [9], up to polymer membranes [10] etc. Membrane process has the advantages of easily establishing in impressively large scale and integrating with other separation or reaction processes.…”
