Co-pyrolysis of chicken feathers and macadamia nut shells, a promising strategy to create nitrogen-enriched electrode materials for supercapacitor applications.

Global food waste emits substantial quantities of nitrogen to the environment (6.3 Mtons annually), chicken feather (CF) waste is a major contributor to this. Pyrolysis, in particular co-pyrolysis of nitrogen-rich and lignocellulosic waste streams is a promising strategy to improve the extent of pyrolytic nitrogen retention by incorporating nitrogen in its solid biochar structure.

The screening of various biochars for Cd removal at relevant soil pH.

Fourteen biochars from seven biomass sources were investigated on their long-term Cd removal. The experiments consisted of a ten-day batch Cd adsorption in a pH-buffered solution (pH = 6) to minimise pH effects. Insect frass, spent peat and chicken manure-derived biochars are promising Cd adsorbents.

Robust, defensible, and fair: The AMEE guide to selection into medical school: AMEE Guide No. 153.

Selection is the first assessment of medical education and training. Medical schools must select from a pool of academically successful applicants and ensure that the way in which they choose future clinicians is robust, defensible, fair to all who apply and cost-effective. However, there is no comprehensive and evidence-informed guide to help those tasked with setting up or rejuvenating their local selection process.

Improving Shared Decision Making in Vascular Surgery: A Stepped Wedge Cluster Randomised Trial.

Objective: Different treatment options are available and feasible for various vascular surgical disorders. Hence, vascular surgery seems an area par excellence for shared decision making (SDM), in which clinicians incorporate the patient's preferences into the final treatment decision. However, current SDM levels in vascular surgical outpatient clinics are below expectations.
