Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

open access: yesGlobal Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Revealing Ionic Transfer Kinetics in Poly(3,4‐Ethylenedioxythiophene)/Multi‐Wall Carbon Nanotubes

open access: yesNano Select, EarlyView.
Binder‐free electrodes are critical for advancing supercapacitor performance. Here, the development of carbon nanotubes electrodes by replacing conventional non‐conducting polymer binders by a conducting polymer was evaluated. Advanced gravimetric tools permits a deep investigation of the various mechanisms related to the ionic/solvent transfers ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Time-to-Voltage Converter With Miller-Impedance Technique for Single-Photon Arrival Time-to-Digital Conversions

open access: yesIEEE Open Journal of Circuits and Systems
A low-power time-to-voltage converter (TVC) is composed of a reconfigurable current-mode integrator and a capacitive voltage holder specifically for random sampling-and-averaging (RSA) time-to-digital conversions (TDC) in time-correlated single-photon ...

Lepidagathis konkanensis sp. nov. (Acanthaceae: Barlerieae) from Lateritic Plateaus of Konkan Region of Western Ghats based on morphological and molecular evidence

open access: yesNordic Journal of Botany, EarlyView.
Lepidagathis konkanensis, a new species from the lateritic plateaus of the Konkan region in Maharashtra, India, is described and illustrated based on distinct morphological and molecular characters. Morphologically and phylogenetically, this species is close to L. mahakassapae and L. dalzelliana, but it can be distinguished by its compact inflorescence,

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.
