For preoperative and intraoperative detection of tumor distribution, numerous multimodal contrast agents, such as magnetic nanoparticles (MNPs) with several examination indicators, are currently in development. However, complex materials, configuration, and cost are required for multimodal contrast agents, accompanied by a high possibility of toxicity and low popularity in clinics. Nevertheless...

The magnetic properties and redetermination of crystal structure of copper(II) acetate monohydrate have been studied. The copper(II) centers are separated by 2.617(1) Å and antiferromagnetically coupled (-2J = 292.2 cm−1), which follows from temperature-dependent magnetic susceptibility measurements in the temperature range 4.2 to 300 K. The magnetic moment at 300 K is about 2.1 Bohr magnetons ...

The work of Brittenham [1], Fischer [2], and others has shown that biomagnetic susceptibility measurements are a uniquely effective, noninvasive method to monitor liver iron in patients with iron overload diseases. However, existing instruments, based on superconducting quantum interference devices (SQUIDs), are too expensive for widespread clinical use. We are developing a prototype biomagneti...

Highlights  Gradient-echo MRI phase contrast depends on the underlying tissue magnetic susceptibility but is orientation-dependent and non-local.  Calculating tissue magnetic susceptibility maps overcomes the orientation-dependent and non-local nature of phase contrast.  Phase and susceptibility are primarily affected by tissue composition. For example, tissues rich in ferritin (stored iron)...

In this study, the effects of various heat treatments on microstructure, mechanical and magnetic properties of HSLA-100 steel were evaluated. The heat treatments consisted of austenitizing at 900°C for 60 minutes, then quenching by different cooling rates via furnace, air, oil and water; and quenched specimens were aged at 600°C for one hour. Optical and field emission scanning electron m...

Abstract West Sumatra has the potential of abundant natural resources in form iron sand, one which is located Pasia Jambak Beach area, Nan Tigo, Padang. Basically sands have magnetite ( Fe 3 O 4 ), hematite α-Fe 2 and maghemite γ-Fe ) can be used as a mineral high economic value. However, sand Beach, no known magnetic mineral. This study aims to investigate content Padang based on its susceptib...

different La concentrations for the purpose of suppressing antiferromagnetism. The values of x prepared are x = 0, 0.15, and 0.5. The samples were grown in single crystal form using an In flux technique, then characterized by x-ray diffraction, magnetic susceptibility, and specific heat. Magnetic susceptibility data reveal that as x increases, the antiferromagnetism of heavy-fermion CeRhIn 5 is...

The magnetic susceptibility of liquid-mercury-based alloys containing5,8,15 and Bat .% Na is investigated. Changes in the paramagneric contribution of the conduction electrons are discussed in terms of negative excess molar volume. The anomalous variation of the total magnetic susceptibility with the composition is analysed. The occurrence of Hg, units appears to be corroborated from the compos...
