Advanced Materials Interfaces, EarlyView.Epitaxial Cr(1+δ)Te2 thin films were synthesized via hybrid Pulsed Laser Deposition (PLD) that combined Molecular Beam Epitaxy (MBE) techniques with PLD. Control of the Cr intercalation, δ, enabled modulation of magnetic anisotropy, Curie temperature, and transport properties.

Raman and Raman optical activity of glycosaminoglycans
Chemical Communications, 2010The first Raman optical activity spectra of glycosaminoglycans (GAGs) are reported and exhibited characteristic features specific to the major chemical differences in GAGs (N-, O-sulfation and N-acetylation). Furthermore, the lack of major features between 1050-1150 cm(-1) for heparin and N-acetyl heparin suggests that these molecules do not adopt ...

Annual Review of Analytical Chemistry, 2012
The past decade has seen an enormous increase in the number and breadth of imaging techniques developed for analysis in many industries, including pharmaceuticals, food, and especially biomedicine. Rather than accept single-dimensional forms of information, users now demand multidimensional assessment of samples.

From portable Raman to mobile Raman: the progression of Raman spectroscopy
Next-Generation Spectroscopic Technologies XI, 2018Over the past 15, Raman systems have evolved from benchtop analyzers interfaced with a laptop computer to a smart phone based sensor. The journey from the first handheld system to newly developed smartphone-based Raman sensors is presented. Combining a Raman sensor with a smartphone enables advanced processors and cloud computing, greatly expanding ...

Raman and surface Raman spectroscopy with ultraviolet excitation
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005We record the accurate and reliable Raman spectra of benzoic acid (BA), p-nitrobenzoic acid (PNBA) and o-nitrobenzoic (ONBA) in aqueous solution with ultraviolet excitation. And we find that the ultraviolet (UV) Raman spectrum of aqueous BA solution has one-to-one correspondence to that of BA solid whereas the others are less resemble to the solid ...

Raman and resonance-Raman scattering by erythrocyte ghosts
Biochimica et Biophysica Acta (BBA) - Biomembranes, 19751. We present the laser-Raman spectra of human erythrocyte ghosts, isolated by standard conditions and compare these with the spectra of lecithin liposomes and fat-free serum albumin. 2. The hydrocarbon stretching modes of membrane lipids are temperature sensitive and may serve as a index of hydrocarbon chain motion. 3.

Raman Imaging and Raman Mapping
2009Raman spectroscopy can be used to non-destructively add image contrast in visualizing structures and dynamics in living systems and materials. Image contrast can be derived from any information contained in Raman spectra, including band intensities, positions and widths.

Coherent anti‐Stokes Raman scattering in Raman lasers and Raman wavelength converters
Laser & Photonics Reviews, 2010AbstractIn this paper recent research progress on the use of Coherent Anti‐Stokes Raman Scattering (CARS) in Raman lasers and Raman wavelength converters is reviewed. The latest insights in the physical nature and behavior of CARS are addressed, and the recent performance breakthroughs in CARS‐based Raman wavelength conversion are discussed.

Raman, Resonance Raman and Electronic Raman Spectroscopy
1989The theory and practice of Raman, resonance Raman, and electronic Raman spectroscopy are outlined. Resonance Raman spectra are usually characterized by the development of intense overtone and combination tone progressions (A-term Scattering). This form of spectroscopy yields detailed information regarding the resonant excited state since only ...
