MXenes stretch hydrogel sensor performance to new limits

Performance limits in sensor localization

In this paper, we study performance limits of sensor localization from a novel perspective. Specifically, we consider the Cramér-Rao Lower Bound (CRLB) in single-hop sensor localization using measurements from received signal strength (RSS), time of arrival (TOA) and bearing, respectively, but differently from the existing work, we statistically analyze the trace of the associated CRLB matrix (...

Fundamental Performance Limits of Wireless Sensor Networks

Understanding the fundamental performance limits of wireless sensor networks is critical towards their appropriate deployment strategies. Both the data transmission rate and the lifetime of sensor networks can be constrained, due to interference among the transmissions and the limited energy source of the sensor. In addition to presenting the general results with respect to the maximum sustaina...

Limits to human performance

Introduction In 1950, Maurice Herzog and Louis Lachenal became the first climbers to reach the summit of an 8000 m peak (Annapurna, 8091 m). Since that pioneering achievement, tens of thousands of mountaineers have ventured to Nepal, Pakistan, Tibet and China to climb the 14 peaks that rise above 8000 m. Some have succeeded. Some have died in the attempt. Climbing above 8000 m is a severe test ...

TiC2: a new two-dimensional sheet beyond MXenes.

MXenes are attracting attention due to their rich chemistry and intriguing properties. Here a new type of metal-carbon-based sheet composed of transition metal centers and C2 dimers rather than individual C atom is designed. Taking the Ti system as a test case, density functional theory calculations combined with a thermodynamic analysis uncover the thermal and dynamic stability of the sheet, a...
