Modification of glass screen printed electrodes with graphene quantum dots for enhanced power output in miniaturized microbial fuel cells.

This paper demonstrates screen-printing technique, Glass Screen printed (GSP) on glass layer with Graphene Quantum Dots (GQDs) via drop casting approach to manufacture electrodes for Miniaturized Microbial Fuel Cells (MMFCs). MMFCs are viable options to sustainably operate low-power devices such as sensors, implantable medical devices, etc. However, the technology is still not fully mature for practical applications due to limitations of output power.

The process of implementing culture change across a city-operated long-term care home and the importance of stakeholder engagement.

This article describes the Quality Improvement (QI) initiative of a culture change model, CareTO. CareTO is a made-in-Toronto, resident-driven, person-centred approach to care that was implemented across all units of a City of Toronto-operated Long-Term Care (LTC) home during the COVID-19 pandemic. The City of Toronto's Seniors Services and Long-Term Care (SSLTC) Division partnered with an external QI team to support the implementation of CareTO at the pilot site.

S-BIRD: A Novel Critical Multi-Class Imagery Dataset for Sewer Monitoring and Maintenance Systems.

Computer vision in consideration of automated and robotic systems has come up as a steady and robust platform in sewer maintenance and cleaning tasks. The AI revolution has enhanced the ability of computer vision and is being used to detect problems with underground sewer pipes, such as blockages and damages. A large amount of appropriate, validated, and labeled imagery data is always a key requirement for learning AI-based detection models to generate the desired outcomes.

Isolation and Characterisation of Electrogenic Bacteria from Mud Samples.

To develop efficient microbial fuel cell systems for green energy production using different waste products, establishing characterised bacterial consortia is necessary. In this study, bacteria with electrogenic potentials were isolated from mud samples and examined to determine biofilm-formation capacities and macromolecule degradation. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry identifications have revealed that isolates represented 18 known and 4 unknown genuses.

Modelling the dispersion of flashing jets using CFD.

Risk assessments related to industrial environments where gas is kept in liquid form under high pressure rely on the results from predictive tools. Computational Fluid Dynamics (CFD) is one such predictive tool and it is currently used for a range of applications. One of the most challenging application areas is the simulation of multiphase flows resulting from a breach or leakage in a pressurised pipeline or a vessel containing liquefied gas.
