Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

Antiferromagnetic ground state in the MnGa$_4$ intermetallic compound

open access: yes, 2018
Magnetism of the binary intermetallic compound MnGa$_4$ is re-investigated. Band-structure calculations predict antiferromagnetic behavior in contrast to Pauli paramagnetism reported previously.

Sustainable Synthesis of Bio‐Based Magnetic and Conductive Wood for Electromagnetic Interference Shielding Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Synthesis and characterization complexes of bis (2-mercaptobenzimidazole) mercury (II) with transition metal (Ni (II), Pd (II), and Pt (II))

open access: yesZanco Journal of Pure and Applied Sciences, 2020
Treatment of 2-Mercaptobenzimidazol (HL) with the mercuric acetate (Hg(OAc)2) give the complex[Hg(L)2] (1). Then the multinuclear complexes of the type [M2Hg2(L)4Cl4] were prepared through the reaction of complex (1) with each of NiCl2.6H2O, PdCl2 and ...

Synthesis and characterization of modified κ-carrageenan for enhanced proton conductivity as polymer electrolyte membrane. [PDF]

open access: yesPLoS ONE, 2017
Polymer electrolyte membranes based on the natural polymer κ-carrageenan were modified and characterized for application in electrochemical devices. In general, pure κ-carrageenan membranes show a low ionic conductivity.

Extremely low-frequency spectroscopy in low-field nuclear magnetic resonance

open access: yes, 2009
We demonstrate a new phenomenon in nuclear magnetic resonance spectroscopy, in which nuclear spin transitions are induced by radio frequency irradiation at extremely low frequencies (of the order of a few Hz).

Serum metabonomics of acute leukemia using nuclear magnetic resonance spectroscopy

open access: yesScientific Reports, 2016
Acute leukemia is a critical neoplasm of white blood cells. In order to differentiate between the metabolic alterations associated with two subtypes of acute leukemia, acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML), we investigated ...
