Cost minimisation in micro-hydro systems using pumps-as-turbines [PDF]
The use of reverse-running pumps as turbines (PATs) is a promising technology for small-scale hydropower. This thesis reviews the published knowledge about PATs and deals with some areas of uncertainty that have hampered their dissemination ...

Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels
Advanced Materials Interfaces, EarlyView.Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...
