A biomolecule-assisted pyrolysis method has been developed to synthesize sulfur-doped graphitic carbon nitride (CNS) nanosheets. During the synthesis, sulfur could be introduced as a dopant into the lattice of carbon nitride (CN). Sulfur doping changed the texture as well as relative band positions of CN. By growing CN on preformed sulfur-doped CN nanosheets, composite CN/CNS heterojunction nan...
A special relational structure, called genealogical tree, is introduced; its social interpretation and geometrical realizations are discussed. The numbers Cn,k of all abstract genealogical trees with exactly n+1 nodes and k leaves is found by means of enumeration of code words. For each n, the Cn,k form a partition of the n-th Catalan numer Cn, that means Cn,1 + Cn,2 + · · ·+ Cn,n = Cn.

The preparation and X-ray crystal structures of (CyNC)Au(I)CN, (n-BuNC)Au(I)CN, and (i-PrNC)Au(I)CN.0.5CH(2)Cl(2) are reported and compared with those of (MeNC)Au(I)CN and (t-BuNC)Au(I)CN, which were previously described. These linear molecules are all organized through aurophilic interactions into three structural classes: simple chains ((CyNC)Au(I)CN and (t-BuNC)Au(I)CN), side-by-side chains ...
In the present article we study the asymptotic behavior of the sums n≤x cn+1 pn+1 − cn pn and n≤x pn+1 cn+1 − pn cn , and of the series ∞ n=1 cn+1 pn+1 − cn pn α , where p n denotes the n-th prime number while c n stands for the n-th composed number.
OBJECTIVE The (CTG)(n) polymorphism in the serum carnosinase (CN-1) gene affects CN-1 secretion. Since CN-1 is heavily glycosylated and glycosylation might influence protein secretion as well, we tested the role of N-glycosylation for CN-1 secretion and enzyme activity. We also tested whether CN-1 secretion is changed under hyperglycemic conditions. RESULTS N-glycosylation of CN-1 was either ...
