A ratiometric fluorescent nanosensor, comprising biomass‐derived iron‐doped carbon dots as the probe and silver nanoclusters as the internal reference, was immobilized onto a polyvinyl alcohol nanofiber membrane via electrospinning. A deep learning model, integrated into a smartphone application, accurately quantified chlorpyrifos by analyzing images ...

ABSTRACT The numerical approximation of nonlinear chaotic differential systems, such as the modified stretch‐twist‐fold (STF) flow and multi‐bond chaotic attractors, presents a significant challenge due to their sensitive dependence on initial conditions and complex dynamics where analytical solutions are unattainable.

ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling ...

ABSTRACT Precipitation of isothermal ω phase is an effective way to strengthen the metastable β‐Ti alloys but generally severely embrittles the materials by suppressing stress‐induced martensitic transformation and deformation twinning. Here, we architect heterogeneous structures with tailored ω phase in a metastable β‐Ti‐20Zr‐12Nb‐2Sn alloy via ...

The Ceiling Height of Wildland Fire Plumes in Quasi‐Steady Stratified and Sheared Boundary Layers
Abstract Radar observations from a prescribed fire experiment reveal a large‐scale, billow‐like vorticity structure associated with the plume head near the onset of plume bending. This bending limits the vertical extent of the plume and defines the characteristic plume ceiling height.
