    Abstract Light-weight aluminum (Al) alloys have widespread applications. However, most Al alloys have inherently low mechanical strength. Nanotwins can induce high strength and ductility in metallic materials. Yet, introducing high-density growth twins into Al remains difficult due to its ultrahigh stacking-fault energy. In this study, it is shown that incorporating merely several atomic percent of Fe solutes into Al enables the formation of nanotwinned (nt) columnar grains with high-density 9R phase in Al(Fe) solid solutions. The nt Al-Fe alloy coatings reach a maximum hardness of ≈5.5 GPa, one of the strongest binary Al alloys ever created. In situ uniaxial compressions show that the nt Al-Fe alloys populated with 9R phase have flow stress exceeding 1.5 GPa, comparable to high-strength steels. Molecular dynamics simulations reveal that high strength and hardening ability of Al-Fe alloys arise mainly from the high-density 9R phase and nanoscale grain sizes.

    Abstract Film-forming techniques and the control of heat release in micro-energetic chips or devices create challenges and bottlenecks for the utilization of energy. In this study, promising nano-Al/MoO 3 metastable intermolecular composite (MIC) chips with an uniform distribution of particles were firstly designed via a convenient and high-efficiency electrophoretic deposition (EPD) technique at room temperature and under ambient pressure conditions. The mixture of isopropanol, polyethyleneimine, and benzoic acid proved to be an optimized dispersing agent for EPD. The kinetics of EPD for oxidants (Al) and reductants (MoO 3 ) were systematically investigated, which contributed to adjusting the equivalence ratio of targeted energetic chips after changing the EPD dynamic behaviors of Al and MoO 3 in suspension. In addition, the obtained nano-Al/MoO 3 MIC energetic chips showed excellent heat-release performance with a high heat release of ca. 3340 J/g, and were successfully ignited with a dazzling flame recorded by a high-speed camera. Moreover, the fabrication method here is fully compatible with a micro-electromechanical system (MEMS), which suggests promising potential in designing and developing other MIC energetic chips or devices for micro-ignition/propulsion applications.

    Abstract Ageism manifests as stereotyping of or discrimination against people-usually older adults-because of their age. Since ageism contributes to global mental health inequity among older people, responding to their needs should be a clinical, ethical, and policy priority. This article suggests how relatively simple, low-cost, high-yield interventions can be implemented globally and domestically to improve the well-being and quality of life of older individuals.

    Abstract Background: Primary adrenal failure is considered to be an extremely rare disease presenting in the ED, with an incidence reported to be as low as 50 cases per 1,000,000 persons (Klauer, 2017). I would like to present a case of a young man who presented to the ED, with what I suspected to be this rare entity.
    Case report: A 26year old otherwise healthy male presented to our ED with complaints of weakness, nausea, vomiting, and hiccups of 1.5-day duration. He also complained of lightheadedness, describing it as if he was going to pass out. Other than slight tachycardia (100) and darkened skin, his physical exam, ROS, PMH, Family and Social History, were all unremarkable. His sodium returned at 111, and he was later noted to become more confused in the ED prompting the emergent use of Hypertonic Saline. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Albeit a rare disease entity, EPs need to keep this life threatening disease process in the back of their minds when presented with a patient with vague symptoms such as weakness or fatigue, electrolyte abnormalities and darkening of their skin.

  8. Article: Call of Duty - What are Physicians' Obligations During Crises?

    Giwa, Al O / Urdaneta, Alfredo E / Wedro, Benjamin

    The Journal of emergency medicine

    2022  Volume 63, Issue 4, Page(s) 592–596

    Abstract Background: Society allows physicians the privilege and responsibility of caring for patients. Those responsibilities demand that their knowledge and technical expertise meet standards defined and policed by their colleagues, through medical societies or governmental entities. However, the fiduciary duty that patients' interests are held above those of the physicians' is an ethical precept that is tested when society is under threat.
    Discussion: Disasters that stress society are a constant and can present themselves in a myriad of ways to include medical, meteorological, or political. Minimizing the potential damage to the quality and quantity of life of the population is dependent upon public safety personnel and health care professionals who may put their health and safety in harm's way to care for patients. These acts may be taken for granted or assumed to be part of the professional obligations of physicians and other health care workers who work at the bedside. The obligations of physicians to their patients and society may differ from those not in the medical field, and the level of risk deemed acceptable by the physician and by society should be clearly delineated.
    Conclusion: Despite the conflict between normative and descriptive ethics, in times of disaster, physicians must respond to the call of duty. This duty is contingent on the responsibility being shared with governmental agencies and health care facilities, to mitigate the risks borne by those who answer the call.
