Effect of catalyst support on dihydroeugenol hydrodeoxygenation on low cost FeNi catalyst to produce renewable alkane fuel
Solventless hydrodeoxygenation of dihydroeugenol was investigated in a continuous reactor at 300 °C under 30 bar over different nickel-iron catalysts, prepared using a two-step impregnation method. The following catalysts were studied: mesoporous FeNi/Al$_2$O$_3$, FeNi/SiO$_2$ and FeNi/H-MCM-48 as well as microporous FeNi/H-Beta-300, FeNi/H-Beta-38, FeNi/H-Y-5.1, FeNi/H-MCM-48 and FeNi/USY-30 [...]

Tunable Dirac nodal line in orthorhombic RuO$_2$
The pressure evolution of RuO$_2$ is studied using single-crystal x-ray diffraction in a diamond anvil cell, combined with ab initio band-structure calculations. The tetragonal rutile structure transforms into the orthorhombic CaCl$_2$-type structure above 13 GPa under quasihydrostatic pressure conditions. [...]

Low-temperature luminescence of LiB$_3$O$_5$: Ag glass excited by synchrotron radiation
Low temperature physics 51(4), 509 - 512 () [10.1063/10.0036247]  GO
The paper presents the results of studies of photoluminescence (PL) of glass at a temperature of 12.6 K under the influence of synchrotron radiation λexc = 45 nm. It was found that the obtained PL spectra consist of three bands $λ_{mon}$ = 278, 336, and 379 nm. [...]

Dynamics of highly-ionized diiodomethane: Coulomb explosion, energy exchange and rotating fragments
The dissociation dynamics of diiodomethane molecules (CH$_2$I$_2$) have been investigated following absorption of 98 eV XUV photons. In the measurement at the reaction microscope endstation at the free-electron laser FLASH2, ionic fragments created by 4d core ionization followed by Auger decay have been detected in coincidence [...]

Flux Growth and Characterization of Bulk InVO$_4$ Crystals
Crystals 13(10), 1439 () [10.3390/cryst13101439]  GO
The flux growth of InVO$_4$ bulk single crystals has been explored for the first time. The reported eutectic composition at a ratio of V$_2$O$_5$:InVO$_4$ = 1:1 could not be used as a self-flux since no sign of melting was observed up to 1100 °C. [...]

Observations of the singly Cabibbo-suppressed decays $ {\Xi}_c^{+}\to p{K}_S^0 $, $ {\Xi}_c^{+}\to \Lambda {\pi}^{+} $, and $ {\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+} $ at Belle and Belle II
[Belle II Preprint 2024-028; KEK Preprint 2024-29; arXiv:2412.10677]
Using data samples of 983.0 fb$^{−1}$ and 427.9 fb$^{−1}$ accumulated with the Belle and Belle II detectors operating at the KEKB and SuperKEKB asymmetric-energy e$^{+}$e$^{−}$ colliders, singly Cabibbo-suppressed decays $ {\Xi}_c^{+}\to p{K}_S^0 $, $ {\Xi}_c^{+}\to \Lambda {\pi}^{+} $, and $ {\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+} $ are observed for the first time. The ratios of branching fractions of $ {\Xi}_c^{+}\to p{K}_S^0 $, $ {\Xi}_c^{+}\to \Lambda {\pi}^{+} $, and $ {\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+} $ relative to that of $ {\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+} $ are measured to be$ {\displaystyle \begin{array}{c}\frac{\mathcal{B}\left({\Xi}_c^{+}\to p{K}_S^0\right)}{\mathcal{B}\left({\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+}\right)}=\left(2.47\pm 0.16\pm 0.07\right)\%,\\ {}\frac{\mathcal{B}\left({\Xi}_c^{+}\to \Lambda {\pi}^{+}\right)}{\mathcal{B}\left({\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+}\right)}=\left(1.56\pm 0.14\pm 0.09\right)\%,\\ {}\frac{\mathcal{B}\left({\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+}\right)}{\mathcal{B}\left({\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+}\right)}=\left(4.13\pm 0.26\pm 0.22\right)\%.\end{array}} $Multiplying these values by the branching fraction of the normalization channel, $ \mathcal{B}\left({\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+}\right)=\left(2.9\pm 1.3\right)\% $, the absolute branching fractions are determined to be$ {\displaystyle \begin{array}{c}\mathcal{B}\left({\Xi}_c^{+}\to p{K}_S^0\right)=\left(7.16\pm 0.46\pm 0.20\pm 3.21\right)\times {10}^{-4},\\ {}\mathcal{B}\left({\Xi}_c^{+}\to \Lambda {\pi}^{+}\right)=\left(4.52\pm 0.41\pm 0.26\pm 2.03\right)\times {10}^{-4},\\ {}\mathcal{B}\left({\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+}\right)=\left(1.20\pm 0.08\pm 0.07\pm 0.54\right)\times {10}^{-3}.\end{array}} $The first and second uncertainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty in $ \mathcal{B}\left({\Xi}_c^{+}\to {\Xi}^{-}{\pi}^{+}{\pi}^{+}\right) $..

Measurement of the inclusive branching fractions for ${B}_{s}^{0}$ decays into D mesons via hadronic tagging
[Belle II Preprint 2024-030; KEK Preprint 2024-32; arXiv:2411.14032]
We report measurements of the absolute branching fractions $\mathcal{B}\left({B}_{s}^{0}\to {D}_{s}^{\pm }X\right)$, $\mathcal{B}\left({B}_{s}^{0}\to {D}^{0}/{\overline{D} }^{0}X\right)$, and $\mathcal{B}\left({B}_{s}^{0}\to {D}^{\pm }X\right)$, where the latter is measured for the first time. The results are based on a 121.4 fb$^{−1}$ data sample collected at the Υ(10860) resonance by the Belle detector at the KEKB asymmetric-energy e$^{+}$e$^{−}$ collider. [...]

Search for CP violation in $ {D}_{(s)}^{+}\to {K}_S^0{K}^{-}{\pi}^{+}{\pi}^{+} $ decays using triple and quadruple products
[Belle II Preprint 2024-025; KEK Preprint 2024-24; UCHEP-24-05; arXiv:2409.15777]
We perform the first search for CP violation in $ {D}_{(s)}^{+}\to {K}_S^0{K}^{-}{\pi}^{+}{\pi}^{+} $ decays. We use a combined data set from the Belle and Belle II experiments, which study e$^{+}$e$^{−}$ collisions at center-of-mass energies at or near the Υ(4S) resonance [...]
