Synthesis of noble metal nanoparticles embedded in the shell layer of core-shell poly(styrene-co-4-vinylpyridine) micospheres and their application in catalysis
pubs.acs.org/doi/abs/10.1021/cm703378c
The noble metal nanoparticles of Pd, Au, and Ag embedded in the shell layer of core−shell poly(styrene-co-4-vinylpyridine) micospheres were synthesized, and the catalytic activity of the shell-embedded Pd nanoparticles was investigated. To increase the accessible active site and therefore increase the catalytic activity of noble metal nanoparticles, th...

Nano Lett., 2012, 12, 5033-5038: Highly Porous Metal Oxide Networks of Interconnected Nanotubes by Atomic Layer Deposition
Mesoporous metal oxide networks composed of interconnected nanotubes with ultrathin tube walls down to 3 nm and high porosity up to 90% were fabricated by atomic layer deposition (ALD) of alumina or titania onto templates of swelling-induced porous block copolymers. The nanotube networks possessed dual sets of interconnected pores separated by the tube wall whose thickness could be finely tuned by...

[J. Am. Chem. Soc.] Surface-Initiated Group Transfer Polymerization (SI-GTP) Mediated by Rare Earth Metal Catalysts
We present the first example of a surfaceinitiated group transfer polymerization (SI-GTP) mediated by rare earth metal catalysts for polymer brush synthesis. The experimentally facile method allows rapid grafting of polymer brushes with a thickness of >150 nm in <5 min at room temperature. We show the preparation of common
poly(methacrylate) brushes and demonstrate that SI-GTP is a versati...

Highly sensitive and selective fluorescent sensor for Zn2+/Cu2+ and new approach for sensing Cu2+ by central metal displacement
An ‘‘off-on’’ Zn2+ and ‘‘on-off’’ Cu2+ fluorescent chemosensor
C was designed and synthesized. The binding of C and Zn2+/Cu2+
is chemically reversible by the addition of EDTA disodium
solution; moreover, the fluorescence emission signal of ZnC
decreased with the addition of Cu2+, demonstrating that ZnC
could detect Cu2+ via metal displacement.

Cis–trans isomerization and spin multiplicity dependences on the static first hyperpolarizability for the two-alkali-metal doped saddle[4]pyrrole compounds
Doping two alkali-metal atoms (Li and Na) into
the saddle-shaped saddle[4]pyrrole forms four new twoalkali-
metal-doped compounds with alkalide or electride
characteristic.

Abnormal current– voltage characteristics and metal– insulator transition of amorphous Fe-doped carbon films on Si substrates
Amorphous Fe0.05–C0.95 films have been deposited on n-type Si substrates using direct current magnetron sputtering. The structure and electrical properties of the films/Si are investigated. The film/Si deposited at room temperature exhibits abnormal current–voltage (I–V) characteristics, whose current
increases slowly at first, and then increases to a very large value when the v...

Abnormal current–voltage characteristics and metal–insulator transition of amorphous carbon film/silicon heterojunction
The amorphous carbon film/n-Si (a-C/n-Si) heterojunctions have been fabricated by direct current magnetron sputtering at room temperature, and their current–voltage characteristics have been investigated. The results show that these junctions have good rectifying properties in the temperature range 80–300 K. The interesting result is that the current–voltage curve changes dramati...

Abnormal I-V characteristics and metal-insulator transition of Fe-doped amorphous carbon/silicon p-n junction
Simple p-C/n-Si junctions have been fabricated by magnetron sputtering at room temperature and their current-voltage （I-V） characteristics have been investigated. The p-n junctions show good rectifying properties in a large voltage scope and interesting I-V characteristics. The most interesting
phenomenon observed in these p-n junctions is that the temperature dependence of some junction resist...
