A Promising Point‐of‐Care Testing Strategy: Ultrasmooth Gold Nanogroove Arrays Biosensor Combined with Initial Rate Analysis

Advanced Science, EarlyView.
This work reports a nanoplasmonic biosensing platform with exceptional surface sensitivity (0.618 nm nm−1, Δn = 0.117 nmol) and narrow linewidth (≈20 nm) under normal incidence. By integrating a miscellaneous‐protein strategy with initial rate analysis (IRA), this sensor can detect 1 ng mL−1 of AFP in serum with a broad linear range (1–104 ng mL−1 ...

Effects of additive noise on the stability of glacial cycles

, 2016
It is well acknowledged that the sequence of glacial-interglacial cycles is paced by the astronomical forcing. However, how much is the sequence robust against natural fluctuations associated, for example, with the chaotic motions of atmosphere and ...

Movement Mechanisms Harness Lévy Flight for Energy‐Efficient Wastewater Treatment in Microalgae–Bacteria Systems

Advanced Science, EarlyView.
Here, our novel model that integrates metabolism with motility dynamics reveals that microalgae shift bacterial movement toward Lévy flight patterns, enhancing encounter rates and self‐aggregation. This microecological manipulation reduces energy costs, strengthens functions such as pollutant removal and system stability.

Optimal Chirality Enhances Long‐Range Fluctuation‐Induced Interactions in Active Fluids

Advanced Science, EarlyView.
Chiral active particles move along curved trajectories arising from the interplay of propulsion and self‐rotation. How chirality influences fluctuation‐induced forces in active matter systems remains unclear. It is shown that particle shape dictates this effect: chirality suppresses forces for circular particles but can enhance them for elongated ones,

Mapping uncertainty using differentiable programming

AIChE Journal, EarlyView.
Abstract Uncertainty quantification (UQ) and propagation is a ubiquitous challenge in science, permeating our field in a general fashion, and its importance cannot be overstated. Recently, the commoditization of differentiable programming, motivated by the development of machine learning, has allowed easier access to tools for evaluating derivatives of
