Revealing CO dissociation pathways at vicinal copper (997) interfaces.

Size- and shape-tailored copper (Cu) nanocrystals can offer vicinal planes for facile carbon dioxide (CO) activation. Despite extensive reactivity benchmarks, a correlation between CO conversion and morphology structure has not yet been established at vicinal Cu interfaces. Herein, ambient pressure scanning tunneling microscopy reveals step-broken Cu nanocluster evolutions on the Cu(997) surface under 1 mbar CO(g).

Effect of Quality of Repair on Clinical and Structural Outcomes of Rotator Cuff Repair.

Background: Anatomic repair of a torn rotator cuff tendon on the greater tuberosity (GT) is an important surgical goal in rotator cuff repair. However, few studies have investigated whether the efforts made to maximize coverage of the GT are associated with the clinical and structural outcomes after rotator cuff repair surgery.

Purpose: To investigate whether the quality of repair at the time of surgery is associated with clinical and structural outcomes after surgery and to identify factors influencing the quality of repair.

Direct Observation of Atomic-Scale Gliding on Hydrophilic Surfaces.

Nanoscale friction behavior on hydrophilic surfaces (HS), influenced by a probe gliding on a confined water layer, has been investigated with friction force microscopy under various relative humidity (RH) conditions. The topographical and frictional responses of the mechanically exfoliated single-layer graphene (SLG) on native-oxide-covered silicon (SiO/Si) and mica were both influenced by RH conditions. The ordinary phenomena at ambient conditions (i.

Prevalence of Accessory Bones and Tarsal Coalitions Based on Radiographic Findings in a Healthy, Asymptomatic Population.

Background: Accessory bones and tarsal coalitions are the most common developmental variations of the foot and ankle. However, their clinical implications are not well understood because there is no established prevalence data in the normal population and the reported prevalence varies widely. Therefore, we aimed to investigate the incidence of accessory ossicles and tarsal coalitions in a healthy, asymptomatic Korean population.

Reduction and fixation of anterior inferior tibiofibular ligament avulsion fracture without syndesmotic screw fixation in rotational ankle fracture.

Objective: We aimed to present the radiographic and functional outcomes of anatomical reduction and fixation of anterior inferior tibiofibular ligament (AITFL) avulsion fracture without syndesmotic screw fixation in rotational ankle fracture.

Methods: We retrospectively reviewed 66 consecutive patients with displaced malleolar fracture combined with AITFL avulsion fracture. We performed reduction and fixation for the AITFL avulsion fracture when syndesmotic instability was present after malleolar fracture fixation.
