A Homeostatic Photonic Device Integrating Vapor‐Regulated Thermo‐Optical Feedback Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
An inorganic homeostatic photonic device is designed to autonomously regulate light, temperature, and vapor sorption through integrated positive and negative feedback mechanisms at multiple wavelengths. The device uses a graded mesoporous 1D photonic crystal coupled with a photothermal layer.

Predicting Extinction Risk for Data Deficient Bats

open access: yesDiversity, 2018
Conservation biology aims to identify species most at risk of extinction and to understand factors that forecast species vulnerability. The International Union for Conservation of Nature (IUCN) Red List is a leading source for extinction risk data of ...

High prices for rare species can drive large populations extinct: the anthropogenic Allee effect revisited [PDF]

open access: yesJournal of Theoretical Biology, Volume 429, Pages 170-180 (2017), 2017
Consumer demand for plant and animal products threatens many populations with extinction. The anthropogenic Allee effect (AAE) proposes that such extinctions can be caused by prices for wildlife products increasing with species rarity. This price-rarity relationship creates financial incentives to extract the last remaining individuals of a population,

High‐Performance Field‐Effect Transistors and Phototransistors Array Based on Solution‐Processed Quasi‐1D Van der Waals Ta2Pd3S8 Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Herein, the synthesis of Ta₂Pd₃S₈ nanowires is reported via scalable liquid cascade exfoliation and their integration into high‐mobility field‐effect transistors (FETs) and sensitive photodetectors, achieving carrier mobility of up to 27.3 cm2 V⁻¹ s⁻¹ and responsivities of 322.40 A W⁻¹ and 1.85 mA W⁻¹ for single nanowire and network devices ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Risk, Non-Identity, and Extinction

open access: yesThe Monist
Abstract This paper examines a recent argument in favour of strong precautionary action—possibly including working to hasten human extinction—on the basis of a decision-theoretic view that accommodates the risk-attitudes of all affected while giving more weight to the more risk-averse attitudes.

Mastering Proton Activities in Aqueous Batteries

open access: yesAdvanced Materials, EarlyView.
Advanced aqueous batteries are promising alternatives for grid energy storage. Understanding and mastering the proton activities in aqueous electrolytes will guide the design of sustainable and long‐lasting aqueous batteries. This Perspective comments on the current understanding of the thermodynamic and kinetic perspectives of proton activities and ...

From Molecule to Aggregate: Designing AIE Nanocrystals for Low‐Power Backward Third‐Harmonic Generation Angiography

open access: yesAdvanced Materials, EarlyView.
An organic BTHG agent called OTBP with prominent crystallinity is developed. The resonant absorption at 433 nm and prominent crystallinity of OTBP enhance its BTHG efficiency when excited by a 1300 nm femtosecond laser. Tuning the size of OTBP nanocrystals based on Mie scattering theory successfully enables them to achieve high‐contrast muti‐organ ...

Impact of Colored Environmental Noise on the Extinction of a Long-Lived Stochastic Population: Role of the Allee Effect [PDF]

open access: yesPhys. Rev. E 87, 032127 (2013), 2012
We study the combined impact of a colored environmental noise and demographic noise on the extinction risk of a long-lived and well-mixed isolated stochastic population which exhibits the Allee effect. The environmental noise modulates the population birth and death rates.
