Precision in nuclear magnetic resonance (NMR) spectroscopy and resolution in magnetic resonance imaging (MRI) are thought to be fundamentally limited by the transverse relaxation time. With the recent advent of radiofrequency amplification by stimulated emission of radiation (RASER), it is becoming apparent that RASERs can break these fundamental limitations and provide significant improvements in the resolution of NMR spectra and the resolution in MRI images. In this article, we show that carbon-13 RASERs can be controlled by changes to the magnetic field homogeneity and the spin coupling network.

Architectural distortions (ADs) detected on digital breast tomosynthesis (DBT) are more frequently associated with nonmalignant pathologies than those detected on digital mammography. To evaluate outcomes of ADs detected by DBT alone with no ultrasound correlate and nonmalignant results on core needle biopsy (CNB) when adopting a management strategy selectively incorporating imaging surveillance. This retrospective study included patients with ADs detected by DBT alone with no ultrasound correlate and nonmalignant results on stereotactic CNB with 12 vacuum-assisted 9-gauge cores from July 1, 2020, to December 31, 2023.

Transition metal tellurides (TMTes) are promising anodes for potassium-ion batteries (PIBs) due to their high theoretical specific capacity and impressive electronic conductivity. Nevertheless, TMTes suffer from persistent capacity degradation due to the large volume expansion, high ion-diffusion energy barriers, and the dissolution/shuttle of potassium polytellurides (KTe). Herein, a heterostructured CoTe composite equipped with a self-catalytic center (N-CoTe/LTTC) is developed, exploiting its low-tortuosity tunneling, chemical tunability, and self-catalytic properties to elevate cycling stability to new heights.
