At physiological conditions, most proteins or peptides can fold into relatively stable structures that present on their molecular surfaces specific chemical patterns partially smeared out by thermal fluctuations. These nanoscopically defined patterns of charge, hydrogen bonding, and/or hydrophobicity, along with their elasticity and shape stability (folded proteins have Young's moduli of ∼1 × 1...

Aiming at boosting the photocatalytic activities of rutile and anatase TiO2 surfaces, an in-depth investigation stoichiometric reduced (1 1 0) 0 1) decorated with bipyramidal trapezoidal Ag5 atomic quantum clusters (AQCs) is carried out. In this study, density functional theory (DFT) plus a Hubbard correction (U) implemented to explore geometric electronic properties such systems. It found that...

The flat sheets of the purple membrane from Halobacterium halobium contain only a single protein (bacteriorhodopsin) arranged in a hexagonal lattice. After freeze-drying at -80 degrees C (a method that is superior to air-drying), shadowing with tantalum/tungsten, and image processing, structural details on both surfaces are portrayed in the range of 2 nm. One surface is rough and lattice lines ...

We describe a simple optical method that employs measurement of the interaction energy of a liquid crystal (LC) with a surface (the so-called anchoring energy) to report proteins captured on surfaces through specific interactions with immobilized binding groups. To define the sensitivity and dynamic range of the response of the LC, we covalently immobilized a tyrosine-containing, 13-residue pep...

Motivated by the definition of super-Teichm\"uller spaces, and Penner-Zeitlin's recent extension this to decorated space, as examples super Riemann surfaces, we use Ptolemy relations obtain formulas for $\lambda$-lengths associated arcs in a bordered surface. In special case disk, are able give combinatorial expansion diagonals polygon spirit Ralf Schiffler's $T$-path type $A$ cluster algebras....

Our previous study has shown that the decorated tubules (collectively known as the decorated spongiome) of the contractile vacuole complex (CVC) in Paramecium are the site of fluid segregation, as the binding of microinjected monoclonal antibody (mAb) DS-1 to the tubules reduced the CVC's fluid output. In this study, we showed by immunogold labeling on cryosections that the antigenic sites for ...

Here we demonstrate that the photoactivity of Au-decorated TiO2 electrodes for photoelectrochemical water oxidation can be effectively enhanced in the entire UV-visible region from 300 to 800 nm by manipulating the shape of the decorated Au nanostructures. The samples were prepared by carefully depositing Au nanoparticles (NPs), Au nanorods (NRs), and a mixture of Au NPs and NRs on the surface ...

The paper is partly based on research done for the EU-funded (IST2004-2.4.9) project ALIS (Automated Legal Intelligent System) on Intellectual Property Law. We describe the development process of the ALIS Intellectual Property ontology from both a legal and a technical perspective. We discuss the scope and the features of this IP ontology, the lessons learned, and the problems solved. This is d...

Cu2O nanostructures of cubic or octahedral shape as well decorated with gold nanoparticles were synthesized by a chemical process. The electrochemical activity these for the oxygen evolution reaction (OER) in alkaline media was assessed dark and under solar light irradiation. Electrodes modified cubic-shaped Cu2O-Au revealed both enhanced electrocatalytic OER over octahedral-shaped ones, which ...

The outer surfaces of mycobacteria, including the organism that causes tuberculosis, are decorated with an array immunomodulatory glycans. Among these lipooligosaccharides (LOSs), a class molecules for which function remains poorly understood. We describe chemical synthesis glycan portion tridecasaccharide LOS from opportunistic pathogen Mycobacterium kansasii. target contains number unusual st...
