Prussian blue analogue-derived Ni and Co bimetallic oxide nanoplate arrays block-built from porous and hollow nanocubes for the efficient oxygen evolution reaction.

Effective oxygen evolution reaction (OER) catalysts composed of Earth-abundant transition metals are crucial for sustainable energy conversion and storage. Metal-organic frameworks (MOFs) with tunable compositions are promising precursors for the fabrication of hollow and porous electrocatalysts. However, pulverous MOFs usually suffer from agglomeration during pyrolysis, greatly reducing the activity of their derived catalysts.

On the least signless Laplacian eigenvalue of a non-bipartite connected graph with fixed maximum degree.

In this paper, we determine the unique graph whose least signless Laplacian eigenvalue attains the minimum among all non-bipartite unicyclic graphs of order with maximum degree Δ and among all non-bipartite connected graphs of order with maximum degree Δ, respectively.

Tension band wiring through double-cannulated screws as a new internal fixation method for treatment of olecranon fractures: a randomized comparative study.

Objective: The aim of this study was to assess the therapeutic effects and complications of tension band wiring (TBW) through the use of double-cannulated screws versus conventional TBW in the treatment of olecranon fractures.

Methods: Eligible participants were randomly assigned to 2 groups to undergo different methods of fixation. The related indices and data of the 2 groups were collected for comparative analysis after an average follow-up of 32.

[Analyses of risk factors for deep vein thrombosis in lower extremities].

Objective: To explore the risk factors of deep vein thrombosis (DVT) in lower extremities.

Methods: Retrospective data analyses were performed for a total of 1264 DVT patients at our department from January 2010 to December 2012.

Results: Among them, 984 cases (77.

[Endovascular therapy for traumatic arterial injury].

Objective: To explore the clinical efficacies of endovascular therapy for traumatic arterial intima injury, arterial pseudoaneurysm and arteriovenous fistula.

Methods: From October 2009 to December 2011, 24 patients of arterial intima injury, arterial pseudoaneurysm and arteriovenous fistula underwent endovascular therapy including embolism and stent implantation, etc.

Results: Among them, 14 patients were punctured directly and another 10 were punctured after the exposure of arteries.

[Clinical treatment of application of deep venous thrombosis by retrievable vena cava filter].

Objective: To summarize the clinical experiences of treating deep venous thrombosis (DVT) with retrievable vena cava filter.

Methods: A total of 180 patients with DVT in unilateral lower extremity were recruited. There were 82 males and 98 females with an average age of 46 years old.

[Latest cognition of treatment on deep vein thrombosis of lower extremity].

Objective: To explore the effects of surgical procedure combined with the intravascular minimal invasive technique for the treatment of deep vein thrombosis (DVT) of lower extremity.

Methods: At the curse of disease from six hours to ninety days, one hundred and two patients with DVT including one hundred and three lower extremities had received surgical procedure and intravascular minimal invasive treatment.

Results: There were not procedure-related morbidities in 102 cases, and symptoms disappeared, all procedures were successful based on angiography.
