Carbon-coated CoFe-CoFeO composite particles with high and dual-band electromagnetic wave absorbing properties.

SiO and TiO, as conventional dielectric shells of ferromagnetic/dielectric composite particles, can protect ferromagnetic particles from aggregation and oxidation, but contribute little to electromagnetic loss. In this work, we designed nano-assembled CoFe-CoFeO@C composite particles, in which ferrites with high permeability were dielectric elements and carbon was introduced as protective layers, aiming for high-efficiency microwave absorption. These assembled particles with different CoFe contents were prepared through solvothermal methods and subsequent hydrogen-thermal reduction.

CoFe and CoFe@SiO Nanospheres with Tunable Diameters for High-Performance Electromagnetic Wave Absorption.

Ferromagnetic metal/alloy nanoparticles have attracted extensive interest for electromagnetic wave-absorbing applications. However, ferromagnetic nanoparticles are prone to oxidization and producing eddy currents, leading to the deterioration of electromagnetic properties. In this work, a simple and scalable liquid-phase reduction method was employed to synthesize uniform CoFe nanospheres with diameters ranging from 350 to 650 nm for high-performance microwave absorption application.

[Effect of electroacupuncture intervention on ERK 1/2 signaling and TNF-α and IL-1β protein levels in the substantia Nigra in rats with Parkinson's Disease].

Objective: To observe the effect of electroacupuncture(EA) on phosphalized extracellular regulated protein kinases(p-ERK) 1/2 signaling pathway and tumor necrosis factor (TNF)-α and IL-1β protein levels in the substantia nigra (SN) in rats with Parkinson's disease (PD), so as to explore its mechanism underlying improvement of PD.

Methods: 32 male SD rats were randomly and averagely divided into normal control group, sham-operation group, model group and EA group. PD model was established by intra-dermal-injection of rotenone(1 mg/kg, dissolved in DMSO and saline, concentration: 0.

[Impacts of electroacupuncture on ubiquitin-proteasome system in rats with Parkinson's disease].

Objective: To explore action mechanism of electroacupuncture (EA) on treatment and prevention of Parkinson's disease (PD).

Methods: Fifty clean-grade SD rats were randomly divided into a normal group, a control group, a model group, a pretreatment group and a treatment group, ten rats in each one. The PD model was established by subcutaneous injection of rotenone in neck-back skin (2 mg/kg, dissolved in sun-flower oil, 2 mg/mL in density).
