Bilinear rotations like BIRD, TANGO, BANGO, and BIG-BIRD allow the rotation of an isolated spin without couplings, i.e. bilinear intereactions, in one way, while rotating spins with a matched coupling in another way. All four types of robust bilinear rotations with COB-compensation up to 750 Hz couplings are derived and applied in a HMBC/HSQC-COSY supersequence for isotropic samples and in a J-resolved type experiment using a partially aligned sample.

High critical field superconductors are less sensitive to magnet quenching, providing even higher fields. They can be cooled using cryogens like Helium, but simply using an oscillating pressure field. Using solar or wind energy, the cheap cooling promises magnetic resonance at high field, low operating cost, and renewable energy. Such magnets, made compact, can be used to prepolarise chemical samples, to be analysed in benchtop NMR systems, with better nuclear magnetic resonance spectra.

We present a technology that allows for the direct writing of conductive tracks on cylindrical substrates as receiver coils for magnetic resonance (MR) experiments. The structures are written with high precision, which has two benefits. First, the real structures behave very similarly to the simulated designs, reducing the component variation; second, this allows for the writing of coils apart from the fairly straightforward solenoidal coils, thereby making complex designs available for MR microcoils.

The magic angle spinning (MAS) technique of solid state NMR requires samples to be rapidly rotated within a magnetic field. The rotation rate speed record is 150 kHz, or 9 million RPM, and hence MAS turbines hold the world rotation speed record for extended objects. The containers holding the samples are made of the strongest materials known, to be able to withstand the excessive centrifugal forces. To overcome the speed limit, this paper delineates a way to do so using an optical tweezers setup

In contrast to adiabatic excitation, recently introduced SORDOR-90 pulses provide effective transverse 90° rotations throughout their bandwidth, with a quadratic offset dependence of the phase in the x,y plane. Together with phase-matched SORDOR-180 pulses, this enables a direct implementation of the Böhlen–Bodenhausen approach for frequency-swept pulses for a type of 90°/180° pulse–delay sequence. Example pulse shapes are characterised, and an application is given with a 19F-PROJECT experiment.
