Tunable Reversible Photochromic Ultralong Organic Phosphorescence via a Universal Phenylpyridine Noncovalent Assembly Strategy

Advanced Science, EarlyView.
A concise supramolecular assembly strategy using α‐cyclodextrin and phenylpyridine derivatives affords dual‐functional materials with switchable multicolor photochromism and tunable ultralong organic phosphorescence, offering new platforms for various photonic applications. ABSTRACT Supramolecular photochromic materials capable of reversible alteration

A Phosphorylation‐Induced Micellization Switch in the Low‐Complexity Domain of TDP‐43

Advanced Science, EarlyView.
Phosphorylation of TAR DNA‐binding protein's 43 kDa (TDP‐43) low‐complexity domain by casein kinase 1 delta (CK1δ) acts as a molecular switch, redirecting its self‐assembly from macroscopic phase separation toward finite‐sized, spherical block‐copolymer micelles of ∼30 nm.

A Paradox of LED Road Lighting: Reducing Light Pollution Is Not Always Linked to Energy Savings

Energies
A variety of LED types can be employed for street and road lighting purposes. White phosphor-converted LEDs represent the most widely used option. However, amber LEDs are increasingly being used to reduce some negative effects associated with light ...

Unveiling a Near‐Total Rear Passivation for High Performance of Ultra‐Thin ACIGS

Advanced Science, EarlyView.
Ultra‐thin solar cells of (Ag,Cu)(In,Ga)Se2 (ACIGS) suffer from rear interface recombination, limiting their performance. To tackle it, a full coverage plasma enhanced chemically vapor‐deposited 8 nm porous SiOx passivation layer was implemented and evaluated. It is shown that a combination of the near‐complete passivation from silica and the formation

Fractal Characteristics of the Auroral Oval Structure According to the All-Sky Camera Data in Apatity for 2013–2020

Russian Journal of Earth Sciences
The spatial structure of polar auroras is described by the fractal dimension of glow fluctuations and its anisotropy from direction. The fractal dimension is estimated from the slope in the logarithmic axes of the spectrum in the range of 1.5–50 km ...

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

The “Sky-Coloured Clouds” or Twilight Glows [PDF]

Nature, 1908
THERE can, I think, be no doubt that the numerous descriptions which have appeared of the recent twilight phenomena relate to essentially the same phenomenon as the “sky-coloured clouds”, or, as the late O. Jesse called them, the “luminous night-clouds”. On June 30 and July 1, which seem to have been the principal dates, I was unfavourably situated for

Sky Glow Measurements in the Netherlands [PDF]

Symposium - International Astronomical Union, 2001
Sky glow was measured in the Netherlands in 1992 and in 1997. The 1992 measurements were photographic surveys, assessed in the Netherlands and in Japan, whereas the 1997 measurements were limit-star assessments. In all cases, the number of measurements was very small. The three sets of data are compared.
