Green monomeric photosensitizing fluorescent protein for photo-inducible protein inactivation and cell ablation

open access: yesBMC Biology, 2018
Background Photosensitizing fluorescent proteins, which generate reactive oxygen species (ROS) upon light irradiation, are useful for spatiotemporal protein inactivation and cell ablation.

The Carnegie Supernova Project. I. Third Photometry Data Release of Low-redshift Type Ia Supernovae and Other White Dwarf Explosions [PDF]

open access: yes, 2017
We present final natural-system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004–2009 as part of the first stage of the Carnegie Supernova Project (CSP-I).

Quark deconfinement as a supernova explosion engine for massive blue supergiant stars [PDF]

open access: yesNature Astronomy, 2017
Blue supergiant stars develop into core-collapse supernovae—one of the most energetic outbursts in the Universe—when all nuclear burning fuel is exhausted in the stellar core.

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

SN 2023ixf: The Closest Supernova of the Decade

open access: yesUniverse
Supernova 2023ixf occurred on 18 May 2023 in the nearby galaxy Messier 101 (D≈6.85 Mpc), making it the closest supernova in the last decade. Following its discovery, astronomers around the world rushed to observe the explosion across the electromagnetic ...

The Observer's Guide to the Gamma-Ray Burst-Supernova Connection [PDF]

open access: yes, 2016
We present a detailed report of the connection between long-duration gamma-ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained ...

Gold(I) Phosphine/Phosphido‐Borohydride Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

Understanding Supernova Neutrino Physics using Low-Energy Beta-Beams

open access: yes, 2005
We show that fitting linear combinations of low-energy beta-beam spectra to supernova-neutrino energy-distributions reconstructs the response of a nuclear target to a supernova flux in a very accurate way. This allows one to make direct predictions about

N‐Geranylated Amino Acid Surfactants with Low Critical Micelle Concentrations from Abundant, Naturally Derived Starting Materials

open access: yesChemistryOpen, EarlyView.
Cleaning Up Surfactants: Realising critical micelle concentrations lower than sodium dodecyl sulfate with sustainable surfactants prepared from amino acids and naturally occurring aldehydes. In this work, a simple method for the preparation of N‐alkylated amino acid surfactants in 1–2 steps is reported.
