Reversible, Chemically Gated FRET via Ligand‐Activated Acceptors
Advanced Science, EarlyView.Fluorogen binding turns the compact FAST tag into a tunable FRET acceptor, with ligand chemistry programming spectral overlap and excited‐state lifetimes. Fluorescence‐lifetime imaging reads out energy transfer through the shortened donor lifetime, while simply adding or washing out the dye switches FRET on and off, reversibly mapping the supramodular ...

Supramolecular Enforcement of Planar Tetracoordinate Halides
Angewandte Chemie, EarlyView.A calix[4]pyrrolato‐indium scaffold preorganizes Li4 pockets that trap Cl−, Br−, and I− in strongly flattened to square‐planar tetracoordinate environments. Computations reveal low planarization energies for the heavier halides, while crystallography shows that their geometry is readily modulated by subtle supramolecular and packing effects ...

Advanced Science, EarlyView.A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

Angewandte Chemie, EarlyView.Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Advanced Science, EarlyView.GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides
Advanced Science, EarlyView.Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

The determination of the optimum counting conditions for a ZnS (Ag) scintillation detector [PDF]
, 2004 The methods that use scintillation counting with ZnS(Ag) scintillation detector are widely used for gross alpha activity determination. The common criteria for the selection of optimum counting condition for a ZnS(Ag) scintillation detector do not ...
