Material strain changes bond lengths, which alters their vibrational frequencies and the properties of the material being investigated. Raman spectroscopy is particularly sensitive to strain. With ...

Cu-MOF was pyrolyzed at 400, 500, 600 °C in flowing N 2 (20 sccm) and 700,800 °C in flowing Ar (20 sccm) for 2h to obtain Cu-Graphene-XC (X indicates ... X-ray absorption spectroscopy signals were ...

As an avid runner who loves racing, I’ve been testing the best carbon plate running shoes ever since the original Nike Vaporfly 4% launched. I’ve tried almost every super-shoe released since ...

Zigzag scientists: NUS researchers Lu Jiong (centre), Song Shaotang (right) and PhD student Teng Yu (left) were part of the multidisciplinary research team that developed the Janus graphene ...

In this article, we report hybrid chemiresistor sensor arrays based on single-walled carbon nanotubes (SWNTs) non-covalently functionalized with six different MPs using the solvent casting technique.

"The starting point for this work is two flakes of graphene, which are made up of carbon atoms arranged in a honeycomb structure," says the study's senior author Joshua Folk, a condensed matter ...

Abstract: In this work, we propose a method of efficiently generating a watt-level 1.72 μm ultrafast fiber laser by using a Raman amplifier seeded by a single frequency continuous wave (CW) laser. The ...

Silkworm silk is a protein-based fiber with mechanical ... of Sciences has developed a new method using low-frequency Raman spectroscopy to detect extremely subtle changes in ...
