The ACRIM data in the context of stellar variability [PDF]

, 1990
The Active Cavity Radiometer Irradiance Monitor (ACRIM) total-irradiance data from the Solar Maximum Mission have given a first comprehensive view of solar variability in the stellar sense.

Engineering an Optogenetic pH‐Modulator in Bacteria

Advanced Science, EarlyView.
ABSTRACT Cells in many naturally occurring organisms routinely cooperate to control their extracellular pH in a dynamic and reversible manner, but this capability has been underexplored in synthetic biology. Here, we sought to engineer a microbial system that switches between two states —high and low extracellular pH— with minimal human intervention ...

The effect of temperature and irradiance on the growth and carotenogenic capacity of seven strains of Dunaliella salina (Chlorophyta) cultivated under laboratory conditions

Biological Research, 2005
The carotenogenic microalga Dunaliella salina is cultivated as a natural source of ß-carotene. The 9-cis isomer of ß-carotene is found only in natural sources having commercial advantages over the all-trans isomer due to its high liposolubility and ...

Volcano‐Inspired Dual‐Carbon Network Aerogel for High‐Performance Solar Evaporation With Edge‐Directed Salt Crystallization and Recovery

Advanced Science, EarlyView.
A volcano‐inspired dual‐carbon aerogel featuring hierarchical conduits and an outer carbon‐fiber shell directs rapid water transport, confines heat, and enables directional salt migration. Radial temperature gradients in the conical structure trigger Marangoni‐driven edge‐localized salt crystallization while maintaining an unobstructed photothermal ...

Irradiance levels of phototherapy devices fabricated in Nigeria

Nigerian Journal of Paediatrics
Background: Phototherapy (PT) remains difficult to deliver in many resource- constrained countries, including Nigeria due to the unavailability of devices that can deliver intensive PT (irradiance ≥30 µW/cm2 / nm) needed to treat the more severe cases of

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

Advanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.
