Board level drop impact tests to evaluate electronic package mounts on printed circuit board (PCB) solder joint reliability is critical, especially for handheld and mobile consumer products. Standard drop tests refer the JEDEC specification (JESD22-B

In certain mixtures of nematic and cholesteric liquid crystals, it is found that the metastable final state in an electric‐field‐induced nematic to cholesteric transition depends on the turnoff rate of the applied voltage. Experimental evidence s

The spectrum of light scattered from the isotropic phase of p‐methoxybenzylidene p‐ (n‐butylaniline) (MBBA) has been studied over a 50 °C temperature range above the nematic–isotropic transition temperature (46.2 °C). Light scattered throug

Brillouin-scattering results are reported for monodomain samples of $\ensuremath{\beta}$-methyl butyl $p$ [($p$-methoxy benzylidine)amino] cinnamate in both the smectic-$A$ and -$B$ phases. For both phases theoretical predictions are confirmed concer
