TL;DR: The data presents the first observation of THz-induced molecular alignment in the gas phase, and calculates and measures the degree of both orientation and alignment induced by the THz field in an OCS gas sample, and correlates between the two observables.

TL;DR: In this article, a rigorous analysis of ultrashort pulse shaping by the spectral filtering of dispersed frequency components is presented, focusing on the case of two liquid-crystal spatial light modulators used to provide programmable manipulation of both the phase and amplitude profiles of the shaped waveform in the time domain.

TL;DR: In this article, the authors argue that the large interfacial strain needed to achieve bonding does not necessarily require adiabatic shear instability to trigger, and instead, they suggest that the interaction of strong pressure waves with the free surface at the particle edges can cause hydrodynamic plasticity that effects bonding, without requiring Shear instability, and they proceed on this basis to postulate and confirm a proportionality between critical velocity and the bulk speed of sound.

TL;DR: In this paper, the authors proposed a method for introducing desired electromagnetic radiation into a photonic crystal having at least one defect, wherein the desired EM radiation has a frequency within the photonic bandgap.

TL;DR: It is shown that when a small number of cleavable bonds are selectively installed within the strands of thermosets using a comonomer additive in otherwise traditional curing workflows, the resulting materials can display the same mechanical properties as the native material but can undergo triggered, mild degradation to yield soluble, recyclable products of controlled size and functionality.
