TL;DR: In this article, a fiber-like nanostructured Ti4O7 was synthesized by multistep method and platinized and characterized by X-ray diffraction, transmission electron microscopy (TEM), high-resolution TEM (HRTEM), Xray photoelectron spectroscopy (XPS), and electrochemical testing.

TL;DR: In this paper, supported chemically ordered Pt-Fe intermetallic compounds have been prepared through a straightforward two-stage approach and the nanoparticles of supported intermetall Pt3Fe1 and Pt1Fe1 compounds showed superior electrocatalytic activities towards the oxygen reduction reaction (ORR).

TL;DR: The advanced catalytic activities are mainly attributed to the synergetic effects of electro-active atomic Au and Cu on the particle surface, in which Cu helps to activate the O2 molecule and Au benefits OH(-) desorption.

TL;DR: In this article, the magnetic properties and thermal stability of both the waste and recycled magnet were investigated, and the results showed that the recycled magnet exhibits magnetic properties with remanence (Br) of 12.38 kGs, coercivity (Hci) of 24.89 kG, and maximum energy product (BH)max) of 36.51 kG.

TL;DR: In this paper, an Ag 4 Sn/C intermetallic electrocatalyst was synthesized by a solution phase reduction method assisted with ultrasonic at 0°C. The as-prepared catalyst was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and electrochemical measurements.
