Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Influence of EDTA Coverage Density on Optical Fiber Sensor for Heavy Metal Ion Detection

Nano Select, EarlyView.
This study investigates the influence of chelating agent coverage on the performance of optical fiber sensors for heavy metal ion detection. Ethylenediaminetetraacetic acid (EDTA) was employed to functionalize single‐mode 28 optical fibers (SMF‐28), and the influence of surface coverage uniformity on zinc ion sensing performance was investigated ...

The 1.23 Ga Fjellhovdane rhyolite, Grøssæ-Totak; a new age within the Telemark supracrustals, southern Norway [PDF]

, 2011
The Grøssæ-Totak supracrustal belt is part of the several-kilometre thick Telemark supracrustal sequences that are exposed in southern Norway. Deposition of the Telemark supracrustals spans the period between Telemarkian continental growth at ~1.52-1.48 ...

Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

ChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is

Bimetallic M2B Boride Nanoparticles: A Robust and Recyclable Platform for Dehydration‐Driven Condensation of Aldehydes

ChemistryOpen, EarlyView.
Metal borides (MBs) emerge as a versatile class of nanomaterials, featuring high stability and bifunctional Lewis‐acidic/basic active sites. Despite these properties, their applications in CN bond formation are less explored. Herein, we report the first systematic use of M2B‐type boride nanoparticles as efficient and magnetically recoverable catalysts

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...
