ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Scanning electron microscope studies of Avena coleoptiles during primary leaf emergence
A scanning electron microscope study of the fine structure of coleoptiles of Avena sativa L. cv. Clintford has revealed information about the relationship between aspects of coleoptilar structure and the emergence of the primary leaf. Stomata are located

A Scanning Probe Microscope in My Scanning Electron Microscope? [PDF]
Abstract Scanning probe microscopes (SPMs) designed to fit into scanning elec- tron microscopes (SEMs) are now becoming commercially available and you might ask, "Why would I want to put an SPM in my SEM"? The primary reason is that the too forms of microscope are very complimentary. Each microscope extends the power of the other.

Flexible high-voltage supply for experimental electron microscope [PDF]
Scanning microscope uses a field-emission tip for the electron source, an electron gun that simultaneously accelerates and focuses electrons from the source, and one auxiliary lens to produce a final probe size at the specimen on the order of ...

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Resonant electron heating and molecular phonon cooling in single C$_{60}$ junctions [PDF]
We study heating and heat dissipation of a single \c60 molecule in the junction of a scanning tunneling microscope (STM) by measuring the electron current required to thermally decompose the fullerene cage.
