Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(2003)
We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ...
Finite amplitude elastic waves propagating in compressible solids
(2005)
The paper studies the interaction of a longitudinal wave with transverse waves in general isotropic and unconstrained hyperelastic materials, including the possibility of dissipation. The dissipative term chosen is similar ...
Surface waves in a stretched and sheared incompressible elastic material
(2005)
In this paper, we analyze the effect of a combined pure homogeneous strain and simple shear in a principal plane of the latter on the propagation of surface waves for an incompressible isotropic elastic half-space whose ...
The stress field in a pulled cork and some subtle points in the semi-inverse method of nonlinear elasticity
(The Royal Society, 2007-11-08)
In an attempt to describe cork-pulling, we model a cork as an incompressible rubber-like material and consider that it is subject to a helical shear deformation superimposed onto a shrink fit and a simple torsion. It turns ...
Stoneley waves and interface stability for Bell materials in compression; comparison with rubber
(2005)
Two semi-infinite bodies made of prestressed, homogeneous, Bell-constrained, hyperelastic materials are perfectly bonded along a plane interface. The half-space have been subjected to finite pure homogeneous predeformations, ...
Interface waves in misoriented pre-stressed incompressible elastic solids
(Oxford Journals, 2004-12-17)
Some relationships, fundamental to the resolution of interface wave problems, are presented. These equations allow for the derivation of explicit secular equations for problems involving waves localized near the plane ...
Explicit secular equations for piezoacoustic surface waves: Rayleigh modes
(American Institute of Physics, 2005-09-06)
The existence of a two-partial Rayleigh wave coupled to an electrical field in 2 mm piezoelectric crystals is known but has rarely been investigated analytically. It turns out that the Z cut X propagation problem can be ...
The explicit secular equation for surface acoustic waves in monoclinic elastic crystals
(Acoustical Society of America, 2001-01-25)
The secular equation for surface acoustic waves propagating on a monoclinic elastic half-space is derived in a direct manner, using the method of first integrals. Although the motion is at first assumed to correspond to ...
Some results on finite amplitude elastic waves propagating in rotating media
(Springer, 2004-12)
Two questions related to elastic motions are raised and addressed. First: in which theoretical framework can the equations of motion be written for an elastic half-space put into uniform rotation? It is seen that nonlinear ...
Explicit secular equation for Scholte waves over a monoclinic crystal
(Elsevier, 2004)
Scholte waves are acoustic waves propagating at a fluid/solid interface. They are localized in the neighborhood of the phase boundary in the sense that they decay exponentially in both directions along the normal to the ...
