Temperature-programmed desorption ͑TPD͒ has been used to investigate the adsorption of NO on Pt͕211͖ at 300 K and 120 K. Results show that NO dissociation occurs readily on Pt͕211͖,a s evidenced by the observation of N 2 and N 2 O in the TPD spectrum. Following adsorption at 120 K three NO TPD peaks at 338, 416, and 503 K are observed, in agreement with previous observations. In combination with data acquired in a recent reflection absorption infrared spectroscopy and density functional theory investigation of NO/Pt͕211͖, these peaks are assigned to the desorption of NO from an O-NO complex, the recombinative desorption of N and O atoms, and to desorption of a step-bridged NO species, respectively. These assignments are in disagreement with previous work, where the high-temperature NO peak was assigned to the desorption of step bound NO and the two low-temperature peaks were assigned to the desorption of NO from terrace sites. TPD spectra recorded following adsorption at 300 K, with a heating rate of 1 K s Ϫ1 , show similar features to those recorded following 120 K adsorption. This is also in disagreement with previous observations, where only two NO TPD peaks were observed following adsorption at room temperature. This disagreement can be accounted for by the different heating rates used in the two experiments. The influence of steps on the dissociation of NO on

“…For simple hydroxamic acids, this conversion reaction is known to have an overall percentage of only 28–35 %, where the product is contaminated by the unconverted acid chloride or ester starting material, or an unwanted carboxylic acid side product . Polyacrylic acid and polymethacrylic acid have been converted to their corresponding polyhydroxamic acids through an acid chloride intermediate . However, this route allowed for the presence of the carboxylate compound in the final product due to incomplete conversion to the acid chloride intermediate.…”

The promise of polyhydroxamic acid ligands for the selective chelation of the f-elements is becoming increasingly more apparent. The initial studies of polyhydroxamic acid siderophores showed the formation of highly stable complexes with Pu(IV), but a higher preference for Fe(III) hindered effective applications. The development of synthetic routes toward highly pure and customizable ligands containing multiple hydroxamic acids allowed for the growth of new classes of compounds. While the first round of these ligands focused on the incorporation of siderophore-like frameworks, the new synthetic strategies led to small molecules of various frameworks and even resins for applications in the field of f-element separations and biological desorption. Unfortunately, a lack of consistent stability constant data makes direct comparisons across this body of work difficult. More studies into the stability constants and separations of the f-elements in a variety of pH ranges is necessary to truly realize the potential for polyhydroxamic acid ligands.

A rapid and simple RP-TLC method for simultaneous quantification of pharmacologically important sesquiterpene artemisinin (AM) together with its precursors arteannuin-B (AB) and artemisinic acid (AA) in the inflorescence part of Artemisia annua plant has been developed. The RP-TLC of sesquiterpenes was performed on RP-18 F254 S thin-layer chromatographic plates by developing in mobile phase, containing 0.2% TFA in water/ACN (35:65, v/v). The densitometric determination of AM, AB and AA was carried out after derivatization with anisaldehyde reagent at 426 nm in absorption-reflectance mode.
