The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Design, Synthesis, X‐Ray Crystallographic Characterization, Anticholinesterase and Antioxidant Evaluation, and Molecular Modeling of Novel Dispiroindene‐Pyrrolidine Derivatives as Multifunctional Anti‐Alzheimer Agents

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A novel series of 5‐chloro‐N‐alkyl‐1′,1″‐dimethyl‐4′‐aryldispiro[indene‐2,3′‐pyrrolidine‐2′,3″‐indoline]−1,2″(3H)‐diones (4a–r) was rationally designed and synthesized via a one‐pot multicomponent reaction of N‐alkylated 5‐chloroisatin derivatives, 2‐(arylmethylidene)−2,3‐dihydro‐1H‐inden‐1‐ones (2a–i), and sarcosine (3).

The generation of gravitational radiation by escaping supernova neutrinos

The Astrophysical Journal, 1978
Formulae for the gravitational radiation due to the anisotropic axisymmetric emission of neutrinos from a small source are derived. We find that a burst of neutrinos released anisotropically from a supernova will generate a burst of gravitational radiation that may be comparable in amplitude and energy to the gravitational radiation generated by the ...

Dual‐Stabilized Single‐Site Fe(II) for Catalytic Conversion of CO2 to Propiolic Acid Under Ambient Condition

EcoEnergy, Volume 4, Issue 4, August 2026.
We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.

Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, Volume 29, Issue 22, 1 August 2026.
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 ...

Generalized Hubble Law, Violation of the Cosmological Principle and Supernovae

, 2001
The acceleration of the cosmic expansion has been discovered as a consequence of redshift Supernovae data. In the usual way, this cosmic acceleration is explained by the presence of a positive cosmological constant or quantum vacuum energy, in the background of standard Friedmann models.

Dioxomolybdenum(VI) Complexes Supported by Fluxional Bis(amide)‐Functionalized Aminophenolate Ligands

European Journal of Inorganic Chemistry, Volume 29, Issue 22, 1 August 2026.
New bis(amide) aminophenolate ligands form dioxomolybdenum(vi) and dioxotungsten(vi) complexes showing solvent‐dependent nuclearity. Whilst monomeric complexes featuring methoxide ligands are obtained in methanol, water triggers formation of μ‐oxo‐bridged dimers via oxo exchange, verified by 18O labelling.

Effect of molecular perturbation on cocrystal formation: theophylline and its 8‐halo analogues with flavonoids

Acta Crystallographica Section C, Volume 82, Issue 8, Page 414-426, August 2026.
The tendency for alkaloid–flavonoid cocrystal formation is found to be markedly different for theophylline (Tph) compared to its 8‐halo analogues. Through screening with 13 common flavonoids, Tph is found to form cocrystals with six flavonoids, whereas 8‐Cl‐Tph and 8‐Br‐Tph each form cocrystals with just two, myricetin and kaempferol.
