Metal nanoparticles for sensing applications Elmira Rafatmah, Bahram Hemmateenejad, in Fundamentals of Sensor Technology, 2023 13.2.1.2 Electrochemical sensors modified by magnetic MNPs Magnetic NPs can be used to preconcentrate the catalytic materials at the electrode surface. By surface modification of...
New ternary metal borides, EuOs4B4 and EuIr4B4, have been synthesized from the elements. The compounds were found to crystallize with the structure type of NdCo4B4. Effective paramagnetic moments derived from χ-1 vs. T plots over the range 1.8-800 K are in good agreement with theoretical...
The first part of this paper will deal with the structural properties of binary and ternary fluorides of the 3d transition elements. In the second part the nature of the magnetic exchange interactions will be examined. Finally, the relationships between the magnetic properties and structure will be...

The initial employment of alpha-benzoin oxime (bzoxH(2)) in higher oxidation state 3d metal cluster chemistry has provided access to a new enneanuclear Mn(III) complex with an unprecedented metal-core topology consisting of two triangular [Mn(3)(mu(3)-Omicron(2-))(mu-OmicronNu)(3)](4+...
Groundwater arsenic mobilizations through multi-faucet channels pose a threat to living beings. To combat this, a self-reliant auto-combustive preparation route of magnetic cobalt and nickel oxide nanoparticles (CONP and NONP, respectively) was adopted and tested successfully to scavenge arsenic from...
(iDPC-STEM) has been proved to be quite dose-efficient and sensitive to light elements55,56, which is very suitable for high-resolution imaging of beam-sensitive organic materials like CNS helices. The severely aggregated CNS helices are well separated after prolonged probe sonication, which are ...
16 – Metal oxide structure, crystal chemistry, and magnetic propertiesCommercial interest in ceramic magnets started in the early 1930s with a Japanese patent describing application of copper and cobalt ferrites. The first Golden age of magnetic oxides was the 1950s and the 1960s, when the...
driven by large fluctuations in the price of the rare-earth elements: according to the Ministry of Economy Trade and Industry, Japan, the price of dysprosium metal rose from US$250 per kg in April 2010 to US$2840 per kg in July 2011, while the price for neodymium metal rose from US$42...
