Recently developed polarisation transfer techniques are applied to the 103Rh nuclear magnetic resonance (NMR) of the 103Rh(acac)3 coordination complex in solution. Four-bond 1H–103Rh J couplings of around 0.39 Hz are exploited to enhance the 103Rh

Abstract The cavity inside fullerene C60 provides a highly symmetric and inert environment for housing atoms and small molecules. Here we report the encapsulation of formaldehyde inside C60 by molecular surgery, yielding the supermolecular complex CH

Objective: We report a case of pituitary metastasis (PM) presenting with acute anterior and posterior pituitary dysfunction following a two-decade-long oncologic course marked by disease progression. Case Report: An elderly woman with a history of st

The chemical nature of molecules encapsulated within fullerenes remain debated, with reports proposing a Faraday cage effect. Here, the authors show that H2O and HF molecules encapsulated inside a C60 cage experience a substantial intra-cage electros

The quantum state of a spin ensemble is described by a density operator, which corresponds to a point in the Liouville space of orthogonal spin operators. Valid density operators are confined to a particular region of Liouville space, which we call t

In the majority of hydrogenative parahydrogen-induced polarization (PHIP) experiments, the hydrogen molecule undergoes pairwise cis addition to an unsaturated precursor to occupy vicinal positions on the product molecule. However, some ruthenium-base

Dissolution-dynamic nuclear polarization is able to enhance nuclear magnetic resonance signals, but requires complex procedures to generate hyperpolarized nuclear spins. Here the authors establish a fast and facile method to transfer hyperpolarized s

The Aharonov–Anandan phase is a contribution to the phase acquired by the cyclic evolution of a quantum state, which depends only on the geometric properties of its trajectory. We report the study and the exploitation of the Aharonov–Anandan phas
