Magnetic Resonance Spectroscopy and Sleep Apnea
Using magnetic resonance spectroscopy, researchers at the University of New South Wales Brain Sciences (Sydney, Australia) recently showed that the brain is damaged more severely by obstructive sleep apnea (OSA) and snoring than previously thought.
A recent study at the University of New South Wales Brain Sciences (Sydney, Australia) has shown that the brain is damaged more severely by obstructive sleep apnea (OSA) and snoring than previously thought.
Sleep specialists from the Woolcock Institute at Sydney University used magnetic resonance spectroscopy to study a dozen male patients who had severe, untreated OSA. The researchers found that these men experienced changes in brain biochemistry similar to those experienced by people who have suffered a severe stroke or are dying. Even a small percentage of oxygen desaturation during sleep caused serious effects on the bioenergetic status of the brain.
This study was different from previous sleep apnea studies that focused on re-creating the condition in patients who were already awake. The researchers also found that lack of oxygen while asleep is much worse than while awake because people can compensate much better for lack of oxygen when they are awake.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
Deep Level Transient Spectroscopy Reveals Influence of Defects on 2D Semiconductor Devices

Single Cell and Microplastic Analysis by ICP-MS with Automated Micro-Flow Sample Introduction
April 25th 2024Single cell ICP-MS (scICP-MS) is increasingly seen as a powerful and fast tool for the measurement of elements in individual cells, mainly due to the high sensitivity and selectivity of ICP-MS. Analysis is performed in the same way as single nanoparticle (spICP-MS) analysis, which has become a well-established technique for the analysis of nanoparticles and particles.
