The Raman spectrum of rutile

open access: yes, 1962
The Raman spectrum of rutile has been investigated both at room temperature and at the temperature of liquid air. The Raman lines which, at room temperature are quite wide, are observed to sharpen greatly at the low temperature.

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

RAMPAC: a program for analysis of complicated Raman spectra [PDF]

open access: yes, 1993
A computer program for the analysis of complicated (e.g. multi-line) Raman spectra is described. The program includes automatic peak search, various procedures for background determination, peak fit and spectrum deconvolution and extensive spectrum ...

Surface-Enhanced Raman Scattering Detection of Fipronil Pesticide Adsorbed on Silver Nanoparticles

open access: yesSensors, 2019
This work presents a surface-enhanced Raman scattering (SERS) and density functional theory (DFT) study of a fipronil adsorbed on colloidal silver nanoparticles (AgNPs). A standard curve was established to quantify fipronil within a range of 0.0001–

Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

open access: yesAdvanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

open access: yesAdvanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

The Worst Influence of Raman Spectra Surrounding a Sample: A Study of Containers and Contact Surface Materials to Improve the Raman Signal

open access: yesOptics
Raman spectroscopy is a widely used analytical technique; however, the choice of container material can significantly affect repeatability due to noise and unwanted Raman bands. This paper describes the interaction of excitation radiation with the sample’

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

open access: yesAdvanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

The Raman spectrum of beryllium silicate

open access: yes, 1950
The Raman spectrum of beryllium silicate has been studied using the resonance radiation of mercury as exciter. The spectrum exhibits 25 Raman lines, 17 of which have been recorded for the first time. The Raman lines are extremely sharp.
