Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

open access: yesAdvanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

open access: yesAngewandte Chemie, EarlyView.
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

Fingerless [PDF]

open access: yes, 2017
This reflective poem about the self and being in a new area is based on the total solar eclipse (dubbed the Great American Eclipse) that occurred on August 21, 2017. It explores themes similar to those raised in discussions about the case of Charity Lamb.

Examining the broadband emission spectrum of WASP-19b: A new z band eclipse detection [PDF]

open access: yes, 2013
WASP-19b is one of the most irradiated hot-Jupiters known. Its secondary eclipse is the deepest of all transiting planets, and has been measured in multiple optical and infrared bands.

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

The dynamic effects of solar eclipses of October 25, 2022, and October 14, 2023, on GPS-derived total electron content

open access: yesGeodesy and Geodynamics
This study analyzes total electron content (TEC) variations during two solar eclipse events that occurred on October 25, 2022, and October 14, 2023. The solar eclipse of October 25, 2022, was a partial solar eclipse, while the eclipse of October 14, 2023,

Accuracy of Solar Eclipse Calculation Algorithm Based on Jet Propulsion Laboratory Data Nasa

open access: yesAl-Ahkam, 2020
DE200 and DE405 are Development Ephemeris (DE) series released by the National Aeronautics and Space Administration (NASA) in 1981 and 1997. NASA uses DE405 to predict solar eclipses in 2011-2020.

Solar eclipse

open access: yesEos, Transactions American Geophysical Union, 1972
There will be an eclipse of the sun on Monday, July 10, 1972, with a path of totality passing from northern Alaska southeastward across Canada to Nova Scotia. Much of its path crosses sparsely inhabited parts of Canada, but the province of Prince Edward Island is directly in the path The capital city of Charlottetown is nine miles from the line and ...

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...
