LiCoO2 has been labelled with 17O from 17O-enriched water, and then examined via 7Li, 17O and 59Co solid-state NMR at different charge states. The results reveal the atomic-level environment evolution during the phase transitions, and 17O NMR is found to be more sensitive to the subtle structural changes.

We studied the charging behavior of an amorphous carbon thin film kept at liquid-nitrogen temperature under focused electron-beam irradiation. Negative charging of the thin film is observed. The charg...
The development of active, acid-stable and low-cost electrocatalysts for oxygen evolution reaction is urgent and challenging. Herein we report an Iridium-free and low ruthenium-content oxide material ...
Large-scale chromatin features, such as replication time and accessibility influence the rate of somatic and germline mutations at the megabase scale. This article reviews how local chromatin structur...
The establishment of electrocatalysts with bifunctionality for efficient oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in acidic environments is necessary for the development o...
Extreme conditions of complex materials often lead to a manifold of local environments that challenge characterization and require new advances at the intersection of modern experimental and theoretic...
The investigators will conduct a study around the best way to monitor infants hospitalized with bronchiolitis, the most common lung infection and a leading reason for hospitalization in in...
Vasospasm is a current complication after aneurysmal subarachnoid hemorrhage and often and often associated with brain ischemia. This complication is difficult to detect, because clinical ...
The purpose of this study was to compare ACCM/PALS guidelines performed with and without central venous oxygen saturation monitoring on the morbidity and mortality rate of children with se...
It is anticipated that the use of tissue oxygen monitoring to measure brain tissue oxygen and deltoid muscle oxygen will provide more precise information about focal brain ischemia and sys...
Hypoxic ischemic brain injury is a devastating illness that occurs after cardiac arrest (the heart stopping) and can yield irreversible brain damage, often leading to death. The mainstay i...
Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
The interdisciplinary science that studies evolutionary biology, including the origin and evolution of the major elements required for life, their processing in the interstellar medium and in protostellar systems. This field also includes the study of chemical evolution and the subsequent interactions between evolving biota and planetary evolution as well as the field of biology that deals with the study of extraterrestrial life.
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
Physiologic or biochemical monitoring of the fetus. It is usually done during LABOR, OBSTETRIC and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery.
