The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of l...

Magnetically hidden order is a hypernym for electronic ordering phenomena that are visible to macroscopic thermodynamic probes but whose microscopic symmetry cannot be revealed with conventional neutron or x-ray diffraction. In handful of f-electron systems, the odd-rank multipoles leads parameters vanishing cross-section. Among them, Ce$_3$Pd$_{20}$Si$_6$ known its unique phase diagram exhibit...

In the JWST, Extremely Large Telescopes, and LUVOIR era, we expect to characterize a number of potentially habitable Earth-like exoplanets. However, characterization these worlds depends crucially on accuracy theoretical models. Validating models against observations planets with known properties will be key for future terrestrial Due its sensitivity micro- macro-physical an atmosphere, polarim...

We consider the task of estimating expectation value an $n$-qubit tensor product observable $O_1\otimes O_2\otimes \cdots \otimes O_n$ in output state a shallow quantum circuit. This is cornerstone variational algorithms for optimization, machine learning, and simulation many-body systems. Here we study its computational complexity constant-depth circuits three types single-qubit observables $O...

Molecular dynamics (MD) simulations are performed to investigate the thermal and mass accommodation coefficients (TAC MAC, respectively) for combination of iron(-oxide) air. The obtained values TAC MAC then used in a point-particle Knudsen model effect chemisorption transition regime on combustion behavior (fine) iron particles. interactions $\mathrm{Fe}$ with $\mathrm{N_2}$ $\mathrm{Fe_xO_y}$ ...

ABSTRACT Inside-out planet formation (IOPF) proposes that the abundant systems of close-in Super-Earths and Mini-Neptunes form in situ at pressure maximum associated with dead zone inner boundary (DZIB). We present a model physical chemical evolution protoplanetary disc midplanes follows gas advection, radial drift pebbles, gas-grain chemistry to predict abundances from ?300 au down DZIB near 0...
