The spin population distribution in the ferromagnetically coupled hetero-bimetallic chain compound [MnNi(NO(2))(4)(en)(2)] (en = 1,2-ethanediamine) has been investigated by means of polarized neutron diffraction experiments, and the results compared with those from theoretical estimates obtained via calculations based on density functional theory on dinuclear molecular models of the chain. The ...

The booming electric vehicle industry continues to place higher requirements on power batteries related economic-cost, density and safety. positive electrode materials play an important role in the energy storage performance of battery. nickel-rich NCM (LiNixCoyMnzO2 with x + y z = 1) have received increasing attention due their high density, which can satisfy demand commercial-grade batteries....

Neural network predictions suggested that strength of a high strength steel weld metal with 7 wt. % nickel and 0.5 wt. % manganese could be increased significantly at moderate expense to impact toughness by additions of carbon. Based on this, three experimental weld metals were produced with carbon levels between 0.03 and 0.11 wt. %. Mechanical test results were in agreement with predictions. W...

Cobalt-manganese-nickel oxalates micropolyhedrons were successfully fabricated by a room temperature chemical co-precipitation method. Interestingly, the Co0.5Mn0.4Ni0.1C2O4*nH2O micropolyhedrons and graphene nanosheets have been successfully applied as the positive and negative electrode materials (a battery type Faradaic electrode and a capacitive electrode, respectively) for flexible solid-s...

Tap water from 497 properties using private water supplies, in an area of metalliferous and arsenic mineralisation (Cornwall, UK), was measured to assess the extent of compliance with chemical drinking water quality standards, and how this is influenced by householder water treatment decisions. The proportion of analyses exceeding water quality standards were high, with 65 % of tap water sample...

The cycling performance of nickel-rich lithium nickel cobalt manganese oxide (NMC) electrodes in Li-ion batteries (LIBs) partially depends on the control kinetics degradation processes that result impedance rise. contribution from surface film formation at NMC/electrolyte interfaces is highly dependent initial chemical composition and structure NMC surfaces. Through comparison quantity electroc...

Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...

BACKGROUND Hemodialysis patients are at risk for deficiency of essential trace elements and excess of toxic trace elements, both of which can affect health. We conducted a systematic review to summarize existing literature on trace element status in hemodialysis patients. METHODS All studies which reported relevant data for chronic hemodialysis patients and a healthy control population were e...
