Recently designed dipolar Halbach magnets used in portable MRI systems are much lighter and more compact than standard permanent or superconductive magnets. However, improved designs and manufacturing techniques aiming at lower weight and smaller ext

Low-temperature, metastable electrochromism has been used as a tool to assign pigments in Photosystem I (PS I) from Thermosynechococcus vulcanus and both the white light and far-red light (FRL) forms of Chroococcidiopsis thermalis. We find that a min

Transmit array spatial encoding (TRASE) is an MR imaging technique that achieves k-space encoding through the use of phase gradients in the RF transmit field. Without requiring B

PURPOSE TRASE uses phase gradients in the RF transmit field to encode MRI data. A highly efficient twisted solenoid coil was proposed recently for TRASE imaging for transverse B0 geometries. This novel coil can be rotated to generate a phase gradient

Multimodal probes are an asset for simplified, improved medical imaging. In particular, fluorescence and magnetic resonance imaging (MRI) are sought-after combined capabilities. Here, we show that pyrrolidin-2-one-capped manganese oxide nanoparticles

A radiofrequency (RF) power amplifier is an essential component of any magnetic resonance imaging (MRI) system. Unfortunately, no commercial amplifier exists to fulfill the needs of the transmit array spatial encoding (TRASE) MRI technique, requiring

The excited state dynamics of the red fluorescent protein DsRed have been studied by spectral hole-burning at low temperature. The homogeneous line width Γhom of the S1←S0 0–0 transition of the red (R-) form was obtained from MHz-resolution hole

Reversible conformational changes have been photo-induced in the red fluorescent protein DsRed at low temperature by wavelength-selective laser irradiation. We have found two new fluorescent forms: a shifted-red (SR-) and a new green (G′-) form tha
