Efficient enzymatic hydrolysis of lignocellulosic material remains one of the major bottlenecks to cost-effective conversion of biomass to ethanol. Improvement of... -
Selective Interactions of Porphyrins with Semiconducting Single-Walled Carbon...
A derivatized porphyrin with long alkyl chains, 5,10,15,20-tetrakis(hexadecyloxyphenyl)-21H,23H-porphine, is selective toward semiconducting single-walled carbon nanotubes... -
Thickness-Dependent Morphologies of Gold on N-Layer Graphenes
We report that gold thermally deposited onto n-layer graphenes interacts differently with these substrates depending on the number layer, indicating the different surface... -
2-Aroylbenzoyl Serine Proteases: Photoreversible Inhibition or Photoaffinity...
Phenyl esters of 2-benzoylbenzoates were determined to be inhibitors of the serine protease enzymes chymotrypsin and thrombin. Thus, p-guanidinophenyl 2-benzoylbenzoate (1b)... -

Development of a Zinc Ion-Selective Luminescent Lanthanide Chemosensor for Bi...
Detection of chelatable zinc (Zn2+) in biological studies has attracted much attention recently, because chelatable Zn2+ plays important roles in many biological systems.... -
Enantioselective Direct Aldol-Type Reaction of Azlactone via Protonation of V...
Highly enantio- and diastereoselective direct aldol-type reaction of azlactones with oxocarbenium ions generated by protonation of vinyl ethers using a chiral phosphoric acid... -
Selective Etching of Graphene Edges by Hydrogen Plasma
We devised a controlled hydrogen plasma reaction at 300 °C to etch graphene and graphene nanoribbons (GNRs) selectively at the edges over the basal plane. Atomic force... -
Zigzag Boron−Carbon Nanotubes with Quasi-planar Tetracoordinate Carbons
Four kinds of novel zigzag boron−carbon nanotubes with quasi-planar tetracoordinate carbons (2m, 0, i) (m = 3−6; i = 1−4) have been constructed, and their structures,... -
Femtosecond Dynamics of Isolated Phenylcarbenes
International audience; Understanding the primary photophysical processes in molecules is essential for interpreting their photochemistry, because molecules rarely react from... -
Pyridinium 1,1′-Binaphthyl-2,2′-disulfonates as Highly Effective Chiral Brøns...
We have established, for the first time, a practical synthesis of chiral 1,1′-binaphthyl-2,2′-disulfonic acid (BINSA 1) from inexpensive BINOL. An efficient enantioselective... -
Iridium-Catalyzed Asymmetric Hydrogenation of Cyclic Enamines
The first highly enantioselective iridium-catalyzed hydrogenation of cyclic enamines has been developed. This new reaction provided an efficient method for the synthesis of... -
Macromolecular Helicity Induction in a Cationic Polyacetylene Assisted by an ...
We report the first example of the replication of macromolecular helicity. An optically active helical and anionic polyelectrolyte, the sodium salt of poly(4-carboxyphenyl...
