Hybrid perovskites: Terahertz communications boost

Date: Nov 15, 2017

Author: David Bradley

A hybrid inorganic-organic perovskite that has the same structure as the original mineral can be layered on to a silicon wafer to build a component of future terahertz communications devices according to research from the University of Utah.

Silicon solution: AAS testing in multiple sclerosis

Date: Nov 15, 2017

Author: David Bradley

Transversely -heated graphite furnace atomic absorption spectrometry has been used to show that drinking silicon-rich mineral water can increase the rate of urinary excretion of toxic aluminium ions in people with secondary progressive multiple sclerosis (SPMS).

What a pen and ink: X-rayed papyrus

Date: Nov 15, 2017

Author: David Bradley

X-ray microscopic analyses of 2,000-year-old papyri fragments by scientists at the University of Copenhagen, Denmark, has shown that the black ink used by Egyptian scribes was not comprised of purely carbon-based organic materials as previously thought but contains the metallic element copper not previously identified in such inks.

Journal Highlight: Comparative chemometric analysis for classification of acids and bases via a colorimetric sensor array

Date: Nov 13, 2017

Author: spectroscopyNOW

An 8 sensor colorimetric array was used to analyze acid and basic samples to determine whether PCA, HCA, or LDA is the best chemometric method for classification quantification of analytes within clusters.

Journal Highlight: Chemiluminescence detection of trace iodide with flow injection analysis of KMnO4-carbon dots system

Date: Nov 6, 2017

Author: spectroscopyNOW

Ultra-weak chemiluminescence from the reaction of iodide and KMnO4 was strongly enhanced by carbon nanodots in an acidic medium, allowing the evaluation of iodide in foodstuffs such as seaweed.

Journal Highlight: In vivo X-ray imaging of transport of renal clearable gold nanoparticles in the kidneys

Date: Nov 6, 2017

Author: spectroscopyNOW

Noninvasive X-ray imaging of renal clearable gold nanoparticles in normal and nephropathic kidneys has advanced understanding of the nano-bio interactions while offering a new pathway to noninvasively image kidney dysfunction and local injuries at the anatomical level.

Compromised coffee: Soybean and corn adulterants by CE-MS

Date: Nov 1, 2017

Author: Steve Down

The adulteration of roasted coffee beans with coffee husks, corn or soybean has been detected using capillary electrophoresis-mass spectrometry to measure the monosaccharides originating from the constituent polysaccharides present in the beans.

E-Cigarettes: As dangerous as cigarettes?

Date: Nov 1, 2017

Author: Steve Down

The safety of e-cigarettes has been thrown into doubt following new research which revealed that it induces high levels of proteins in the lungs that are linked with cystic fibrosis, COPD and bronchitis.
