General logarithmic corrections to black-hole entropy
We compute leading-order corrections to the entropy of any thermodynamic system due to small statistical fluctuations around equilibrium. When applied to black holes, these corrections are shown toExpand

Quantum black hole entropy
We derive an exact formula for the dimensionality of the Hilbert space of the boundary states of SU(2) Chern-Simons theory, which, according to the recent work of Ashtekar et al., leads to theExpand

Antifouling and antimicrobial mechanism of tethered quaternary ammonium salts in a cross-linked poly(dimethylsiloxane) matrix studied using sum frequency generation vibrational spectroscopy.
Poly(dimethylsiloxane) (PDMS) materials containing chemically bound (''tethered'') quaternary ammonium salt (QAS) moieties are being developed as new contact-active antimicrobial coatings. SuchExpand

Reflection coefficient for superresonant scattering
We investigate superresonant scattering of acoustic disturbances from a rotating acoustic black hole in the low-frequency range. We derive an expression for the reflection coefficient, exhibiting itsExpand

Schwarzschild horizon dynamics and SU(2) Chern-Simons theory
We discuss the effect of different choices in partial gauge fixing of bulk local Lorentz invariance, on the description of the horizon degrees of freedom of a Schwarzschild black hole as an SU(2)Expand

New holographic entropy bound from quantum geometry
A new entropy bound, tighter than the standard holographic bound due to Bekenstein, is derived for space-times with nonrotating isolated horizons from the quantum geometry approach, in which theExpand

Circular orbits in extremal Reissner–Nordstrom spacetime
Abstract Circular null geodesic orbits, in extremal Reissner–Nordstrom spacetime, are examined with regard to their stability, and compared with similar orbits in the near-extremal situation.Expand

Combinatorial materials research applied to the development of new surface coatings IX: An investigation of novel antifouling/fouling-release coatings containing quaternary ammonium salt groups
Polysiloxane coatings containing chemically-bound (“tethered”) quaternary ammonium salt (QAS) moieties were investigated for potential application as environmental-friendly coatings to control marineExpand

Synthesis and antimicrobial activity of quaternary ammonium-functionalized POSS (Q-POSS) and polysiloxane coatings containing Q-POSS
An array of quaternary ammonium-functionalized POSS (Q-POSS) compounds were synthesized and their antimicrobial properties toward the Gram-negative bacterium, Escherichia coli, and the Gram-positiveExpand

Silver(I) Assisted Metal Exchange Reaction. A Generalized Synthesis of Tris-Chelated Copper(II) Complexes of Neutral N,N-Donors
A novel and direct synthetic route for the syntheses of hexacoordinated cupric complexes involving bidentate N,N-donor ligands has been elaborated. This synthetic strategy has been successfullyExpand
