High temperature batteries require the battery components to be thermally stable and function properly at high temperatures. Conventional batteries have high temperature safety issues such as thermal runaway, which are mainly attributed to the properties of liquid organic electrolytes such as low boiling points and high flammability. In this work, we demonstrate a truly all-solid-state high temperature battery using a thermally stable garnet solid-state electrolyte, a lithium metal anode, and a V2O5 cathode, which can operate well at 100(o)C...

BACKGROUND: Surgeons who work with trainees must address their learning needs without compromising patient safety. METHODS: We used a constructivist grounded theory approach to examine videos of five teaching surgeries. Attending surgeons were interviewed afterward while watching cued videos of their cases. Codes were iteratively refined into major themes, and then constructed into a larger framework. RESULTS: We present a novel framework, Intelligent Cooperation, which accounts for the highly adaptive, iterative features of surgical teaching in the operating room...

Concerns still exist over the safety of prolonged exposure to radio frequency (RF) wireless transmissions and there are also potential data security issues due to remote signal interception techniques such as Bluesniping. Airborne ultrasound may be used as an alternative to RF for indoor wireless communication systems for securely transmitting data over short ranges, as signals are difficult to intercept from outside the room. Two types of air-coupled capacitive ultrasonic transducer were used in the implementation of an indoor airborne wireless communication system...

A deepened investigation on an innovative organic-inorganic hybrid material, referred to as ECS-14 (where ECS = Eni carbon silicates), revealed the possibility to use them as gas sensors. Indeed, among ECS phases, the crystalline state and the hexagonal microplateletlike morphology characteristic of ECS-14 seemed favorable properties to obtain continuous and uniform films. ECS-14 phase was used as functional material in screen-printable compositions and was thus deposited by drop coating for morphological, structural, thermal, and electrical characterizations...

Standard preparation for a surgical procedure requires patients to fast (nulla per os [NPO]) after midnight before their operation. Unfortunately, given the unpredictable nature of operating room scheduling and unavoidable delays, patients may find themselves anxiously waiting and fasting much longer than expected. In recent years, the usefulness of prolonged fasting to prevent pulmonary aspiration has been questioned. According to the American Society of Anesthesiologists (ASA) guidelines, unnecessarily prolonged fasting can be avoided by allowing patients to have clear liquids with the minimal fasting time of only two hours...

This analysis looks at the application of a robust process improvement methodology to achieve a sustained organizational change. The implementation took place in a safety net hospital's operating suites that had a problem with relatively long, nonproductive turnover times between surgical procedures. Organizational leadership empowered stakeholders to use Lean and Six-Sigma tools to develop more efficient organizational processes. These processes were then implemented in a phased approach with careful attention to the organization's culture...

BACKGROUND: The debriefing phase of the surgical safety checklist (SSC) provides the operative team an opportunity to share pertinent intraoperative information and communicate postoperative plans. Prior quality improvement initiatives at our institution focused on the preincision phase of the SSC; however, the debriefing phase has not been evaluated. We aimed to assess adherence to the debrief checklist at our institution and identify areas for improvement. MATERIALS AND METHODS: An observational study was conducted from 2014 to 2016 with a convenience sample of pediatric surgery cases at an academic children's hospital over 8-wk periods annually to evaluate the debriefing checklist across 14 subspecialties...

Patient safety secured by constant vigilance remains a primary responsibility of every anesthesia professional. Although significant attention has been focused on patient falls occurring before and after surgery, a potentially catastrophic complication is when patients fall off an operating room or procedure table during anesthesia care. Because such events are (fortunately) uncommon, and because very little information is published in our literature, we queried 2 independent closed claims databases (the American Society of Anesthesiologists Closed Claims Project and the secure records of a private, anesthesia specialty-specific liability insurer) for information...
