Modulation of the electronic structure metal catalysts is an effective approach to optimize electrocatalytic activity. Herein, we show a surprisingly strong activation effect black phosphorus (BP) on platinum (Pt) give greatly enhanced catalytic activity in hydrogen evolution reaction (HER).

Organic spintronic devices have been appealing because of the long spin lifetime charge carriers in organic materials and their low cost, flexibility chemical diversity. In previous studies, control resistance valves is generally achieved by alignment magnetization directions two ferromagnetic electrodes, generating magnetoresistance. Here we employ a new knob to tune adding thin ferroelectric interfacial layer between electrode spacer: magnetoresistance valve depends strongly on history...

For liquid water in the far-infrared spectrum, phonons of molecular vibrations constitute two bands with a narrow gap at around 30 meV. Interestingly, there are distinct peaks for ice this gap. We demonstrated that come from kinds translational modes. Considering different O–O–O bending constants, we yielded frequencies based on ideal model Ic. These vibrational modes do not exist due to collapse rigid tetrahedral structure. Thus, window remains resonance absorption minimum energy loss...
