Multispectral Photonic Structural Colors via Enhanced Interfacial Interference of Ultrathin Cellulose Nanofiber/MXene Films

open access: yesAdvanced Science, EarlyView.
Fabrication of CNF‐MXene free‐standing films: Ti3C2Tx MXene flakes integrated into a cellulose nanofiber (CNF) matrix through layered self‐assembly using vacuum‐assisted filtration. The layered structure of 4 µm thickness is displayed on SEM image.

Camerobiid mites (Acariformes: Raphignathina: Camerobiidae) inhabiting epiphytic bromeliads and soil litter of tropical dry forest with analysis of setal homology in the genus Neophyllobius

open access: yesEuropean Journal of Taxonomy, 2016
A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N ...

Consequences of Culling in Deterministic ODE Predator-Prey Models [PDF]

open access: yesarXiv, 2016
We show, within the context of the standard class of deterministic ODE predator-prey mathematical models, that predator culling does not produce a long term decrease in the predator population.

A Transient Photoelectric Spiking Neuron Based on a Highly Robust MgO Composite Threshold Switching Memristor for Selective UV Perception

open access: yesAdvanced Electronic Materials, EarlyView.
The artificial UV photoelectric spiking neuron baesd on the LIF circuit is built by integrating a physically transient TS device and an UV photodetector. Artificial photoelectric spiking neuron can selectively detect UV stimuli and encode them into electrical spikes, compensating for this deficiency of human vision and promising for implantable optical

Predator-prey models with competition, Part II: uniform regularity estimates [PDF]

open access: yesarXiv, 2019
We study a system of elliptic equations with strong competition and an arbitrary large number of components. The system is related to a model of predators and prey, with a single and where several predators compete with each other. In this paper we derive regularity estimates of the solutions that are independent of the number of components (i.e ...

Ultrathin High‐Efficiency Zener Diode Fabricated Using Organized ZnS Nanoparticles in Surface‐Grafted Poly(methacrylic acid) Matrix

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a unique approach for fabricating homogeneously dispersed ZnS nanoparticles within an ultra‐thin (<40 nm) polymer matrix. The uniformity of dispersion is ensured through post‐polymerization substitution of Zn2⁺‐terminated side groups in surface‐grafted PMAA brushes. Due to the homogeneous distribution of semi‐conducting nanoparticles,

Micro‐Engraving UV‐Sensitive Thin‐Film Transistor from Metal–Metal Oxide Nanoparticles with Band‐Gap Engineering

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports the development of UV‐sensitive thin‐film transistors using Ag‐doped ZnO nanoparticles. Through an engraving transfer printing process, high‐resolution patterning of conductive channels achieves feature sizes down to 2 µm. The optimal Ag‐doped ZnO nanoparticles enhance electron mobility and UV responsiveness compared to pristine ZnO ...
