Sum frequency generation spectroscopy of the attachment disc of a spider

نویسندگان

چکیده

The pyriform silk of the attachment disc a spider was studied using infrared-visible vibrational sum frequency generation (SFG) spectroscopy. can attach dragline and radial lines to many kinds substrates in nature (concrete, alloy, metal, glass, plant branches, leaves, etc.) with disc. adhesion bear spider's own weight, resist wind on its orb web. From our SFG spectroscopy study, NH group arginine side chain and/or NH2 glutamine amino acid sequence proteins are suggested be oriented It inferred from observed doublet peaks at around 3300 cm−1 that peptide contains two structures.

Theoretical Sum Frequency Generation Spectroscopy of Peptides

Vibrational sum frequency generation (SFG) has become a very promising technique for the study of proteins at interfaces, and it has been applied to important systems such as anti-microbial peptides, ion channel proteins, and human islet amyloid polypeptide. Moreover, so-called "chiral" SFG techniques, which rely on polarization combinations that generate strong signals primarily for chiral mol...

Broadband vibrational sum frequency generation spectroscopy of a liquid surface.

An important advance in surface science has been the evolution of sum frequency generation to the application of studying surface structure and chemistry of liquid surfaces at the molecular-level by probing the vibrational signatures of surface molecules. Recently, broad-bandwidth sum frequency generation (BBSFG) spectroscopy has become an important tool for investigating gas-solid interfaces. ...

Edge pair sum labeling of spider graph

An injective map f : E(G) → {±1, ±2, · · · , ±q} is said to be an edge pair sum labeling of a graph G(p, q) if the induced vertex function f*: V (G) → Z − {0} defined by f*(v) = (Sigma e∈Ev) f (e) is one-one, where Ev denotes the set of edges in G that are incident with a vetex v and f*(V (G)) is either of the form {±k1, ±k2, · · · , ±kp/2} or {±k1, ±k2, · · · , ±k(p−1)/2} U {k(p+1)/2} accordin...
