A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition
Advanced Intelligent Systems, EarlyView.An implantable robotic bladder is presented that can store urine in an origami‐designed enclosure. An inductance sensing principle can monitor and transfer the urine volume in real‐time. It can actively expand based on the amount of urine collected from kidneys and apply on‐demand mechanical compression to assist urination.

Propagation law of gas-coal dust explosion shock waves under different explosion conditions
Gong-kuang zidonghuaTo address the limitations of current experimental and numerical studies on the propagation of gas-coal dust explosion shock waves, which are mostly confined to small-scale laboratory pipelines or local roadways, this study adopted a segmented relay ...

Animal Models and Experimental Medicine, EarlyView.Currently, the animals commonly used to establish animal models of benign airway stenosis (BAS) include mice, rats, pigs, dogs, rabbits, and ferrets. The establishment methods involve one or a combination of two methods such as mechanical injury, tracheal cautery, cuff overpressure intubation, laser injury, and endoscopic silver nitrate cauterization ...

A comparison of measured and theoretical predictions for STS ascent and entry sonic booms [PDF]
, 1983 Sonic boom measurements have been obtained during the flights of STS-1 through 5. During STS-1, 2, and 4, entry sonic boom measurements were obtained and ascent measurements were made on STS-5.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions
Biotechnology and Bioengineering, EarlyView.Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor
The Canadian Journal of Chemical Engineering, EarlyView.A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.
