The ‘first generation’ of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) matrices was found randomly during the early days of MALDI by empirical testing of hundreds of small molecules with molecular weights of typicall

A simple procedure is proposed that allows computing the stress intensity factors for slightly curved and kinked cracks in finite bodies. Basis of the method is the computation of the stress field around a straight crack under externally applied trac

An analytical solution for the linear-elastic problem of an edge-cracked semi-infinite body was given already in 1957. For the numerical evaluation of this solution an iteration procedure had to be applied. This might be the reason why the related an

Crack paths of original Griffith crack and edge crack under biaxial remote mode-I loading after different local disturbances are calculated by using integro-differential equations of first-order perturbation and numerical simulation with FEM respecti

Tunneling cracks driven by drying in a ceramic precursor confined between two glass plates represent a simple type of three-dimensional (3D) crack pattern. They arrange themselves via mutual unloading which causes some cracks to stop whereby the rema

A novel experimental setup was developed which allows controlled quasi-static crack propagation in initially unpoled ferroelectric ceramics as a result of a moving electric field. Applying an electric field on unpoled specimens partially covered with

Even though the degradation of ginsenosides has been thoroughly studied in animals and in vitro using acids, enzymes, and intestinal bacteria, knowledge concerning the systemic availability of ginsenosides and their degradation products in humans is

Crack deflection can occur in a specimen subject to a stress gradient of high tensile stresses near the surface which decreases with increasing depth. Such a stress gradient can be induced by strain incompatibilities. These can for example arise unde

Piezoelectric systems like multilayer actuators are susceptible to damage by crack propagation induced by strain incompatibilities. These can arise under electric fields for example between the electroded and external regions. Such incompatibilities

This paper concerns the thermomechanical response of (Ti,Al)N coatings (on WC–6%Co substrates) subjected to short time thermal laser pulses. The relaxation of compressive stress at transient high temperature leads to tensile stress at ambient tempe
