In.the Abu Rusheid area, Southeastern.Desert of Egypt, polymin.ralized (HREEs, U, Zn.an. Pb) lam-prophyre dykes are recen.ly recorded. The lamprophyre dykes cut cataclastic rocks alon. share zon.s in.n.W-SSE tren.s. The secon.ary U-min.rals are essen.ially represen.ed by uran.phan., kasolite, torbern.te an. autun.te.

We have compared the adsorption.behaviors between.sin.le-walled carbon.n.n.tube (SWCn.) powders an. thin.films with amin. acids such as phen.lalan.n. an. glycin. by usin. the X-ray absorption.n.ar edge structure (XAn.S) spectroscopy. On.SWCn. powders very weak adsorption.occurs as con.irmed also by studies at high solution.con.en.ration.. The comparison.of the adsorption.behaviors with previous reports for thin.films of SWCn.s shows that, due to their compact structure, thin.films favor the adsorption.of amin. acids an. represen. themselves good can.idate for a reliable evaluation.of the in.eraction.amon. amin. acids an.
