Tip-enhanced Raman spectroscopy resolved “resonance” Raman scattering with 1-nm resolution in ultrathin zinc oxide films epitaxially grown on a single-crystal silver surface. Tip-enhanced “resonance” ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

What is the Raman Effect? The Raman Effect is a fundamental scattering phenomenon that occurs when a transparent medium is illuminated by monochromatic light, causing the scattered radiation to ...

Foreword -- Historical Overview -- Theory and Understanding -- Combination of RS and Other Techniques -- Pigments, Dyes and Coloured Agents -- Cultural Heritage Meets Art Forensics -- Jewellery and ...

Graphene is a two-dimensional, one-atom-thick hexagonally organized material composed of sp2 carbon networks with strong covalent bonds. As graphene absorbs only 2.3 percent of incident light, it is ...

Material identification and analysis are crucially important within the forensic analysis field. Similarly to how there is no pre-determined set of materials that comprises all forensic lab analytes, ...

Scientists introduce a single-cell Raman method that monitors beer fermentation in real time, capturing metabolic variation and predicting key process metrics accurately.

Identifying gemstones is not a trivial task. While properties such as color and transparency can help with identification, gemstones such as rubies, spinels, and garnets can be difficult to ...
