Grid‐Shaped, Vertically Aligned Carbon Nanotube Architectures for Electrical, Optical, and Mechanical Bolometers

open access: yesAdvanced Sensor Research, Volume 5, Issue 2, February 2026.
The small geometry of nano/micro sensor devices, down to 3 × 3 µm2, makes them ideal for reliable large‐scale integration into sensor arrays for single‐use biomedical, industrial, and security applications. These devices allow for the efficient conversion of ultraviolet to terahertz radiation into electrical or optical output signals using simple ...

Organic Bulk‐Heterojunction‐Integrated Flexible Perovskite Photodetection Arrays for High‐Speed Broadband Optical Communication

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.

Evaluating the Resistance of Bifacial Perovskite Photodetectors to Xenon Ion Irradiation

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
Bifacial perovskite photodetectors maintain high efficiency and stability after 231 MeV xenon ion irradiation. Key photodetector parameters remain nearly unchanged at low fluence (1010 nucleons cm−2) and show only moderate degradation at high fluence (1011 nucleons cm−2), highlighting their strong radiation tolerance and suitability for optoelectronic ...

Genome‐Wide Codon Reprogramming Enables a Multifactorially Attenuated Influenza Vaccine with Broad Cross‐Protection

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
Genome‐wide codon reprogramming of influenza A virus introduces 1956 synonymous mutations across five segments and elevates CpG content, causing defective NA packaging, loss of NS1 accumulation, and enhanced ZAP‐mediated antiviral responses without affecting RNA or protein synthesis. These mechanisms result in profound attenuation and potent homologous

Demographic Models and Behavioral Assessments Uncover Distinct Species Histories in the Pseudocryptic Nudibranch Genus Hermissenda

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We reconstructed the speciation history of the recently split pseudocryptic nudibranch genus Hermissenda, finding divergence times in the Pleistocene (1.29–0.55 mya). Demographic modeling and behavioral experiments show no gene flow and assortative mating between sympatric species H. crassicornis (s.s.) and H.

Synergistic Plasmonic‐Thermoelectric Enhancement in Semiconducting Carbon Nanotubes for Infrared Light Detection

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
Purified semiconducting carbon nanotube films with controlled amphoteric doping exhibit a synergistic enhancement of plasmonic absorption and thermoelectric response, thereby enabling high‐sensitivity infrared (IR) light detection. By tuning electronic and thermal transport simultaneously, an 11‐fold improvement in photothermoelectric response is ...

Decoupling the Impacts of Climate Change and Human Activities on Terrestrial Vegetation Carbon Sink

open access: yesRemote Sensing
Net ecosystem productivity (NEP) plays a vital role in quantifying the carbon exchange between the atmosphere and terrestrial ecosystems. Understanding the effects of dominant driving forces and their respective contribution rates on NEP can aid in the ...
