Adiabatic pulses for wideband inversion and broadband decoupling
TLDR
In this article, an inversion pulse for wideband application is obtained from a simple nonlinear amplitude modulation wherein the amplitude is modulated in accord with A(t)=A 0 {1-| sin βt| n } and the entire pulse is frequency modulated such that the phase varies as φ(t) =φ 0 + 1/2 kt 2About:

Characterization of lignin derived from water-only flowthrough pretreatment of Miscanthus.
TL;DR: In this article, a water-only flow-through pretreatment is employed to Miscanthus at 160°C for various reaction times to derive the mode of depolymerization process of lignin.

Modulation of brain metabolism by very low concentrations of the commonly used drug delivery vehicle dimethyl sulfoxide (DMSO)
TL;DR: The results show that DMSO is accumulated by brain slices and emphasize that there is no practical concentration of D MSO that can be used in metabolic experiments without effect, so care should be taken when evaluating the actions of drugs administered in combination with this drug.

TL;DR: Results have shown for the first time in an experimental model that preserves the relationship between glia and neurones within the context of brain tissue-that inhibition of L-glutamate transport can exert a significant influence on neurotransmitter-related metabolism.

Methods of, and apparatus for, proton decoupling in nuclear magnetic resonance spectroscopy
TL;DR: In this paper, a radio-frequency pulse is tuned to the frequency of the nuclear species, such as 1 H, to be decoupled or saturated and has a bandwidth adjusted to correspond to the entire chemical shift spectrum, minimizing the amount of radiofrequency power transmitted into a volume of the irradiated sample.

Method and apparatus for broadband decoupling in nuclear magnetic resonance with chirp pulses
Riqiang Fu,Geoffrey Bodenhausen +1 more
TL;DR: In this article, the authors proposed a method for broadband decoupling in nuclear magnetic resonance with chirp and other RF pulses, where the sample is placed in a static field, and a first cycle of chirps pulses are generated, followed by a second cycle of pulses generated by a supercycle of the first and second cycles.

Method for exciting transverse magnetization in magnetic resonance
TL;DR: In this article, a method for exciting transverse magnetization by irradiating a nuclear spin system subjected to a constant magnetic field with a frequency-modulated rf-pulse ("chirp"-pulse) and with a further frequency-modified rfpulse (further chirppulse), for refocusing the magnetization, is characterized in that the rf pulse-(P1) and the further pulse (P2) overlap each other in time at least partially.
