It's commonly known that the electrocatalytic nitrogen (N2) reduction reaction (NRR) can convert N2 and H2O into Ammonia (NH3), one of the most essential chemicals in ecological system. With renewable electricity under mild conditions, it’s envisaged as a promising strategy to replace the industrial Haber-Bosch process. However, this method is still far away from the practical application because the developed NRR electrocatalysts and electrocatalysis system possess low NH3 yield and current efficiency.
As an important non-canonical DNA secondary structure in vivo and in vitro, G-quadruplexes (GQs) have been widely investigated in many fields including biology, medicinal chemistry, supramolecular chemistry and nanotechnology. Vast G-quadruplexes (GQs) are primarily folded by one, two, or four G-rich oligomers, rarely with an exception.
Plasma instabilities known as edge-localized modes (ELMs) are a challenge to stable operation of fusion reactors. Effective ELM control is particularly important in high-confinement, steady-state fusion plasmas such as ITER. The research at DIII-D and EAST found that maintaining high density at the edge of the plasma and a high density ratio between the pedestal bottom and top can reduce the severity of ELMs.
Recently, researchers led by Prof. XU An from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS) reported their new findings that silver nanoparticles (AgNPs) at non-toxic concentrations protect against arsenic induced genotoxicity via attenuating arsenic bioaccumulation and elevating anti-oxidation in mammalian cells.
Recently, a team led by Prof. Huang Qing at the Institute of Intelligent Machines, Hefei Institutes of Physical Science (HFIPS) constructed a novel biosensor based on surface-enhanced Raman spectroscopy (SERS) to detect inflammatory Interleukin-6 (IL-6) protein in serum samples.
