Microwave pyrolysis bio-oil from waste paper and K60 silica gel have been utilised to synthesise mesoporous carbon–silica composites with uniquely tuneable surface properties for the selective recovery of gold from acidic solutions.

The incidence of aortoesophageal fistula after thoracic endovascular aortic repair has increased following an increase in thoracic endovascular aortic procedures. A 68-year-old man was diagnosed with aortoesophageal fistula 6 years after thoracic endovascular aortic repair of a descending aortic aneurysm. Due to massive hematemesis and instability, he underwent a left thoracotomy, graft repair of the aorta with stent removal, gastrostomy, and proximal esophagostomy. Unfortunately, he died 1 week later due to sepsis. Aortoesophageal fistula may present long after thoracic endovascular aortic repair, and clinicians treating such cases should always be aware of this complication.
