Picosecond Spin Current Generation from Vicinal Metal-Antiferromagnetic Insulator Interfaces.

We report the picosecond spin current generation from the interface between a heavy metal and a vicinal antiferromagnet insulator Cr_{2}O_{3} by laser pulses at room temperature and zero magnetic field.

Does supplier concentration matter to investors during the COV1D-19 crisis: evidence from China?

The literature shows that investor attention to customer-supplier disclosure increases when suppliers' information arrival is anticipated. Due to the widespread of city lockdowns in China and the implementation of social distancing to control the COVID-19 pandemic, investor attention to potential disruption of the supply chain spikes, leading to a price devaluation for firms with high supplier concentration risk. We find that a higher degree of supplier concentration is related to more serious stock price declines over the short-term and medium-term windows right after the Wuhan lockdown.

All-solid-state asymmetric supercapacitors based on Fe-doped mesoporous CoO and three-dimensional reduced graphene oxide electrodes with high energy and power densities.

An asymmetric supercapacitor offers opportunities to effectively utilize the full potential of the different potential windows of the two electrodes for a higher operating voltage, resulting in an enhanced specific capacitance and significantly improved energy without sacrificing the power delivery and cycle life. To achieve high energy and power densities, we have synthesized an all-solid-state asymmetric supercapacitor with a wider voltage range using Fe-doped CoO and three-dimensional reduced graphene oxide (3DrGO) as the positive and negative electrodes, respectively. In contrast to undoped CoO, the increased density of states and modified charge spatial separation endow the Fe-doped CoO electrode with greatly improved electrochemical capacitive performance, including high specific capacitance (1997 F g and 1757 F g at current densities of 1 and 20 A g, respectively), excellent rate capability, and superior cycling stability.
