Background: Diabetes in conjunction with a foot burn can compound the challenges in wound healing;however, the impact of diabetes on outcomes of patients with foot burns has not been examined. Methods: A retrospective notes audit was conducted at the Concord Hospital Burns Unit for patients with foot burns who were admitted from 1st January 2012 to 31st December 2013. Data were collected for 15 subjects with foot burns and diabetes and 18 subjects with foot burns and no diabetes as a control group. Subjects were matched for percentage total body surface area of burns. Results: The mean inpatient and total lengths of stay for the diabetic group were 21.27 days and 64.80 days, which were significantly longer (P = 0.090 and P = 0.054) than the 9.61 days and 30.56 days in the control, based on a significance level of 0.10. The diabetic group was significantly older (P = 0.001), at 56.60 years versus 39.44 years in the control. Significantly (P = 0.033) more patients with diabetes were not working (n = 12/15 or 80.00 % versus n = 7/18 or 38.89 %) compared to the control. The diabetic group had higher rates of regrafting (n = 3/15 or 20.00 % versus n = 1/18 or 5.55 %) than the control and significantly (P = 0.013) more amputations (n = 5/15 or 33.33 % versus n = 0 or 0.00 %) compared to the control. fewer patients with diabetes were prescribed pressure garments (n = 2/15 or 13.33 % versus n = 9/18 or 50.00 %), which was significant (P = 0.034). The increased age of patients in the diabetic group correlates with results from other studies. Healing time may be reflected by total length of stay, which was more than double for patients with diabetes, increasing demand and cost of inpatient and outpatient services. Conclusion: This study highlights the importance of recognizing the potential for poorer outcomes for patients with diabetes and indicates the need for more burn prevention education and promotion in this 'at risk' patient group.

There remain great challenges in developing highly efficient electrocatalysts with both high activity and good stability for the ethanol oxidation reaction in alkaline media. Herein, two architectures of tri-metallic PdIrAu/C electrocatalysts are designed and the promoting effect of Au and Ir on Pd toward the ethanol oxidation reaction (EOR) in alkaline media is investigated in detail. On the one hand, the tri-metallic Pd7Au7Ir/C electrocatalyst with a solid solution alloy architecture is less active relative to Pd7Ir/C and Pd/C while the stabilizing effect of Au leads to both a higher activity and a lower degradation percentage after 3000 cycles of the accelerated degradation test (ADT) on Pd7Au7Ir/C than those on Pd7Ir/C. On the other hand, the tri-metallic Pd7Ir@(1/3Au)/C electrocatalyst with a near surface alloy architecture delivers a much higher activity with an improvement up to 50.4% compared to Pd7Ir/C. It is speculated that for the tri-metallic Pd7Ir@(1/3Au)/C electrocatalyst, certain Au atoms are well designed on surfaces to introduce an electronic modification, thus leading to an anti-poisoning effect and improving the EOR activity.

Catalytic decomposition of methane with the addition of sulfur was used to synthesize unique single-walled carbon nanotubes (SWNTs), double-walled carbon nanotubes (DWNTs), and their aligned long ropes. High-resolution transmission electron microscopy (HRTEM) and laser Raman resonance spectroscopy were employed to study the structure and diameter distribution of these carbon nanotubes (CNTs). HRTEM observations show that, with
