Nanoneedles of Mixed Transition Metal Phosphides as Bifunctional Catalysts for Electrocatalytic Water Splitting in Alkaline Media.

In this work, mixed Ni/Co and Ni/Fe metal phosphides with different metal ratios were synthesized through the phosphidization of high-surface-area hydroxides grown hydrothermally on carbon cloth. The materials were characterized by means of X-ray photoemission spectroscopy, X-ray diffraction, energy dispersive X-ray analysis, and electron microscopies. The electrocatalytic performance in the electrochemical water splitting was tested in alkaline media.

Patient positioning on the operative table for more accurate reduction during elastic stable intramedullary nailing of the femur: a technical note.

Elastic stable intramedullary nailing is currently considered a clinical practice standard for the treatment of femoral fractures in children in the age-appropriate group. Malreduction, particularly in rotation, due to the closed reduction technique has been reported. We describe a new technique of positioning on a standard operating table that permits better control of rotational alignment during femoral elastic stable intramedullary nailing.

Factors affecting bone mineral mass loss after lower-limb fractures in a pediatric population.

Background: The purpose of this study was to assess the effects of the durations of cast immobilization and non-weight-bearing periods, and decreases in vigorous physical activity (VPA) on bone mineral parameters in a pediatric population treated for a lower-limb fracture.

Methods: Fifty children and teenagers who had undergone a cast-mediated immobilization for a leg or ankle fracture were prospectively recruited. The durations of cast immobilization and non-weight-bearing periods were recorded for each participant.

Osteoarticular infections in young children: what has changed over the last years?

Osteoarticular infections remain a significant cause of morbidity worldwide in young children. They can have a devastating impact with a high rate of serious and long-lasting sequelae, especially on remaining growth. Depending on the localisation of infection, they manifest as osteomyelitis, septic arthritis, a combination of both (i.

Risk factors for post-traumatic osteoarthritis of the ankle: an eighteen year follow-up study.

Purpose: Long-term studies evaluating risk factors for development of ankle osteoarthritis (OA) following malleolar fractures are sparse.

Methods: We conducted a retrospective cohort study including consecutive patients treated by open reduction and internal fixation for malleolar fracture between January 1988 and December 1997. Perioperative information was obtained retrospectively.
