TL;DR: The phase diagram of the organic superconductor kappa-(ET)2Cu[N(CN)2]Cl has been accurately measured from 1H NMR and ac susceptibility techniques under helium gas pressure to determine the domains of stability of antiferromagnetic and superconducting orders in the pressure vs temperature plane.

TL;DR: NMR spectroscopy of oxygen-17 reveals a drop of the Knight shift in the superconducting state, contradicting previous work and imposing tight constraints on the order parameter symmetry of the system.

TL;DR: The existence of an intermediate charge-ordered phase in the TMTTF family of charge-transfer salts is demonstrated and the absence of an associated magnetic anomaly indicates only the charge degrees of freedom are involved and the lack of evidence for a structural anomaly suggests that charge-lattice coupling is too weak to drive the transition.

TL;DR: The novel solid-state polymerization (SSP) does not occur for 2,5-dichloro-3,4-ethylenedioxythiophene (DCEDOT), and requires a much higher temperature (>130 degrees C) for 2.5-diiodo- 3, 4- methylenedioxyphene (DIEDOT) and X-ray structural analysis of the above dihalothiophenes reveals short Hal.

TL;DR: In this paper, a reduction of Knight shifts was observed for all strain values and temperatures, consistent with a drop in spin polarization in the superconducting state in the quasi-two-dimensional and strongly correlated Sr$_2$RuO$_4$.
