Polymeric film-forming systems for dermal drug delivery represent an advantageous alternative to more conventional topically applied formulations. Their mechanical properties and homogeneity can be characterised with atomic force microscopy (AFM), using both imaging and nanoindentation modes, and Raman micro-spectroscopy mapping. Film-forming polymers, with and without a plasticizer and/or beta...

In this research, the elastic behaviour of two Co thin films simultaneously deposited in an off-normal angle method was studied. Towards this end, two Si micro-cantilevers were simultaneously coated using pulsed laser deposition at an oblique angle, creating a Co nano-string surface morphology with a predetermined orientation. The selected position of each micro-cantilever during the coating pr...

In this paper, based on Kelvin and Linear Standard Solid models, dynamic response and the buckling load of a viscoelastic beam under  lateral and axial loads have been determined. The governing equations have been extracted using Euler  and Timoshenko theories and their analytical solutions have been obtained by using the eigenfunctions expansion method. Buckling load have been calculated by us...

OBJECTIVE Macroporous cement with mechanical properties similar to cancellous bone may improve the treatment of large bone defects in relation to solid acrylic cement. The aim of this study was to compare physical and mechanical characteristics of a polymethyl methacrylate (PMMA) based porous cement with cancellous bone. METHODS Compressive strength and pore size, interconnectivity, and distr...

A computational study is performed to determine the contribution to ultrasound attenuation in carbon fiber reinforced polymer composite laminates of linear elastic scattering by matrix micro-cracking. Multiple scattering approximations are benchmarked against exact computational approaches. Results support linear scattering as the source of observed increased attenuation in the presence of micr...

An aside to the crash course on Basic mathematical structures of neo-classical continuum mechanics Energies through the ether flow, Waves travel to and fro, And with a ratio Their speed you measure. Colours yield their secret hue, And Saturn's rings subdued by you Suggest that gases Might be measured too. Science you freed From cramping mechanistic creed, And by your theory brought The elastic ...

We propose that C4N2 ice clouds observed in Titan’s springtime polar stratosphere arise due to solid-state photochemistry occurring within extant ice cloud particles of HCN-HC3N mixtures. This formation process resembles the halogen-induced ice particle surface chemistry that leads to condensed nitric acid trihydrate (NAT) particles and ozone depletion in Earth’s polar stratosphere. As our anal...

The digested sample can either be filtered prior to analysis or cleaned and concentrated with Thermo ScientificTM SOLAμTM HRP, a highly versatile polymeric micro-scale SPE device offering both polar and non-polar retention of peptides. The ability to elute in low elution volumes reduces the risk of solubility or binding issues as an evaporation step is not required to achieve a concentration fa...

We present a dynamical theory of a two–dimensional martensitic transition in an elastic solid, connecting a high–temperature phase which is nondegenerate and has triangular symmetry, and a low– temperature phase which is triply degenerate and has oblique symmetry. A global mode–based Galerkin method is employed to integrate the deterministic equation of motion, the latter of which is derived by...
