AI Article Synopsis

  • The study investigates electron spin waves in compressed atomic hydrogen gas at high densities (∼10(18) cm(-3)) and low temperatures (0.26 to 0.6 K).
  • A variety of spin wave modes were observed, influenced by the spatial characteristics of the polarizing magnetic field, showcasing the identical spin rotation effect.
  • The research demonstrated the ability to confine and manipulate these spin wave modes by adjusting the location of the maximum magnetic field.

Article Abstract

We present a high magnetic field study of electron spin waves in atomic hydrogen gas compressed to high densities of ∼10(18)  cm(-3) at temperatures ranging from 0.26 to 0.6 K. We observed a variety of spin wave modes caused by the identical spin rotation effect with strong dependence on the spatial profile of the polarizing magnetic field. We demonstrate confinement of these modes in regions of strong magnetic field and manipulate their spatial distribution by changing the position of the field maximum.

The use of cardiac devices, including mechanical circulatory support (MCS), cardiac implantable electronic devices (CIEDs), and pacing wires, has increased and significantly improved survival in patients with severe cardiac failure. However, these devices are frequently associated with acute brain injuries (ABIs) including ischemic strokes, intracranial hemorrhages, seizures, and hypoxic-ischemic brain injury which contribute substantially to morbidity and mortality. Computed tomography (CT) and magnetic resonance imaging (MRI), the standard imaging modalities for ABI diagnosis, can pose significant challenges in this patient population due to the risks associated with patient transportation and the incompatibility of ferromagnetic components of certain cardiac devices with high magnetic field of the MRI.

Synergy between superconductivity and ferromagnetism may offer great opportunities in nondissipative spintronics and topological quantum computing. Yet at the microscopic level, the exchange splitting of the electronic states responsible for ferromagnetism is inherently incompatible with the spin-singlet nature of conventional superconducting Cooper pairs. Here, we exploit the recently discovered van der Waals ferromagnets as enabling platforms with marvelous controllability to unravel the myth between ferromagnetism and superconductivity.

Flexible magnetic sensors, which have advantages such as deformability, vector field sensing, and noncontact detection, are an important branch of flexible electronics and have significant applications in fields such as magnetosensitive electronic skin. Human skin surfaces have complicated deformations, which pose a demand for magnetic sensors that can withstand omnidirectional strain while maintaining stable performance. However, existing flexible magnetic sensor arrays can only withstand stretching along specific directions and are prone to failure under complicated deformations.

Enhanced Transepithelial Riboflavin Delivery Across the Cornea Using Magnetic Nanocarriers.

Keratoconus is a progressive corneal ectasia characterized by irregular astigmatism, leading to corneal scarring and decreased vision. Corneal cross-linking (CXL) is the standard treatment to halt disease progression, but its effectiveness in transepithelial (epithelium-on, epi-on) approaches is limited by the low permeability of the corneal epithelium to riboflavin (Rb). This study aimed to enhance transepithelial Rb penetration in bovine corneas using Rb-modified tannic acid-coated superparamagnetic iron oxide nanoparticles (Rb-TA-SPIONs) under an external magnetic field.

Field analysis of heavy metals in biological samples is essential for assessing their potential threats to human health. The development of portable pretreatment and detection devices is crucial to address this challenge. Herein, a magnetic field-accelerated nonthermal plasma digestion device using dielectric barrier discharge (DBD) is designed for the rapid and environmentally friendly pretreatment of biological samples and subsequently combined with point discharge-optical emission spectrometry (PD-OES) for sensitive determination of heavy metals.
