ConspectusGas sensors are used in various applications to sense toxic gases, mainly for enhanced safety. Resistive particularly popular owing their ability detect trace amounts of high stability, fast response times, and affordability. Semiconducting metal oxides commonly employed the fabrication resistive gas sensors. However, these often require working temperatures, bringing about increased energy consumption reduced selectivity. Furthermore, they do not have enough flexibility, performance is significantly decreased under bending, stretching, or twisting. To address challenges, alternative materials capable operating at lower temperatures with flexibility needed. Two-dimensional (2D) such as MXenes transition-metal dichalcogenides (TMDs) offer surface area conductivity unique 2D structure, making them promising candidates realization Nevertheless, sensing pristine form typically weak unacceptable, terms response, selectivity, recovery time (

Improved sanitation, increased access to health care, and advances in preventive clinical medicine have reduced the mortality morbidity rates of several infectious diseases. However, recent outbreaks emerging diseases (EIDs) caused substantial morbidity, frequency these is likely increase due pathogen, environmental, population effects driven by climate change. Extreme or persistent changes temperature, precipitation, humidity, air pollution associated with change can, for example, expand size EID reservoirs, host-pathogen cross-species host contacts promote transmission spillover events, degrade overall susceptible populations leading new outbreaks. It therefore vital establish global strategies track model potential responses candidate EIDs project their future behaviour guide research efforts on early detection diagnosis technologies vaccine development targets.
