AB  - Carbonized nanostructured polyaniline (C.PANI) was hydrothermally treated in 1 mol dm(-3) KOH at 200 degrees C. The treatment caused significant reduction of micropore volume but negligible changes in mesoporous domain, as evidenced by nitrogen adsorption measurements, as well as significant increase of surface N/C and O/C ratios, as evidenced by XPS method. In comparison to the C.PANI precursor, the new material, denoted as C.PANI.HAT200, delivered twice as high gravimetric capacitances, amounting to 363, 220 and 432 F g(-1), in 6 mol dm(-3) KOH, 2 mol dm(-3) KNO3 and 1 mol dm(-3) H2SO4, respectively, when measured potentiodynamically at a scan rate of 5 mV s(-1). Moreover, its exceptionally high electrocatalytic activity towards the oxygen reduction reaction (ORR), almost one order of magnitude higher than that of C.PANI was evidenced in alkaline media, approaching closely a four-electron pathway. The onset potential for ORR matched the one of platinum-based electrocatalyst. Significant improvements of both capacitive and electrocatalytic properties of C.PANI.HAT200 were discussed in correlation to the modification of surface functional groups. These findings affirm the low temperature hydrothermal post-synthetic modification of N-doped nanocarbons as a route of production of advanced multifunctional carbon materials with exceptional characteristics.

AB  - The solvolysis of (Z)- and (E)-3β-acyloxy-5,10-seco-1(10)-cholesten-5β-ol p-nitrobenzoates 4 and 5 has been investigated and compared with the solvolytic reactivity of the epimeric (Z)- and (E)-5α-p-nitrobenzoates 1 and 2, as well as of the reference compound, i.e. the 1,10-saturated 5α-p-nitrobenzoate. Kinetic data and product analysis revealed that the relative spatial orientation of the 1(10)-olefinic double bond and the chiral center at C(5) in the 10-membered ring, which these secosteroidal 5-p-nitrobenzoates can adopt in the transition state, is the main factor which determines their solvolytic behaviour, so that the esters 1,2 and 5 solvolyse with transannular double bond participation, while such an interaction is not present in the case of the (Z)-5β-ester 4. © 1979.

AB  - Catalytic effects of foreign metal monolayers deposited at underpotentials have been found for the oxidation of formic acid on palladium electrode. Palladium is known to form no poisoning species in oxidation of HCOOH. However, the auto-inhibition of the reaction is found, caused most probably by a species xCx(OH)2. Submonolayer amounts of Pb, Bi, Cd, Tl, Ag and Cu electrosorbed at underpotentials exhibited significant catalytic effects which could be explained by the so-called "third-body" effect in terms of a previously published semiquattitative model. The results have bearing on the understanding of the catalytic effects observed under comparable conditions on platinum and rhodium. Since these effects are orders of magnitude larger than those on palladium, the "third-body" effect probably plays only a minor role at the other two noble metals. © 1978 Elsevier Sequoia S.A.
