Climbing the Hydrogen Evolution Volcano with a NiTi Shape Memory Alloy.

Alkaline water electrolysis is a sustainable way to produce green hydrogen using renewable electricity. Even though the rates of the cathodic hydrogen evolution reaction (HER) are 2-3 orders of magnitude less under alkaline conditions than under acidic conditions, the possibility of using non-precious metal catalysts makes alkaline HER appealing. We identify a novel and facile route for substantially improving HER performance via the use of commercially available NiTi shape memory alloys, which upon heating undergo a phase transformation from the monoclinic martensite to the cubic austenite structure.

An Innovative Approach to Calcaneal Decubitus Ulcerations Through Calcaneal Decorticalization with Use of Localized Bone Marrow and Negative-Pressure Wound Therapy: A Case Study.

Heel decubitus ulcerations are relatively common occurrences that can be limb threatening. There are many options to treat these ulcerations, ranging from conservative wound care to serial debridement with flap reconstruction. However, not all patients are good candidates for major reconstructive surgery.

Exploring Mental Health and Illness in the UK Sports Coaching Workforce.

There is growing international concern about the mental health of those who work in sport, including coaches. However, we currently know little about the prevalence of mental illness and the experience of mental health among coaches, and their perceptions and use of workplace mental health support services. Little is also known about coaches' disclosure of mental illness to, and seeking help from, work colleagues.

Arthroscopy-assisted retrograde drilling of osteochondral lesions of the talar dome.

Traumatic ankle conditions can lead to long-term sequelae if a pathologic process is misdiagnosed. The clinical presentation of an osteochondral lesion of the talar dome requires the clinician to have a high index of suspicion, and advanced imaging is often necessary to make the final diagnosis. Treatment should be initiated once the lesion is appropriately staged by radiologic or magnetic resonance imaging.
