Advanced Science, EarlyView.The configurational‐entropy strategy enables rapid and sensitive ethanol detection using a multicomponent oxide. The high‐entropy (InSnFeZnW)Ox provides enriched oxygen vacancies and diverse adsorption sites that strengthen surface reactivity. The sensor achieves a 5135% ethanol response with fast kinetics and stable long‐term operation.

Polynomial Curve Systems are Exponentially Decaying
The finite global attractor conjecture for the polynomial case was recently solved by using tree lifting algorithm [1]. It remains unclear how fast the pull back of a curve by a polynomial converges to the attractor. In the paper we introduce the ideas of quick returns and barrier lakes to analyze the combinatorial models of curves.

Advanced Science, EarlyView.ABSTRACT The shift from point‐based thermal sensing to filter‐free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spectral regions matching the sensitivity profiles of the red, green and blue (RGB) channels of a digital camera.

Selecciones Matemáticas, 2018 We studied the uniform stabilization of a class of Timoshenko systems with partial dissipation of the beam. Our main result is to prove that the semigroup associated to this model has polynomial decay.

On the irrationality of certain super-polynomially decaying series
Colloquium MathematicumWe give a negative answer to the question by Paul Erdős and Ronald Graham on whether the series ∑n=1∞1(n+1)(n+2)⋯(n+f(n)) has irrational sum whenever (f(n))∞n=1 is a sequence of positive integers converging to infinity. To achieve this, we generalize a classical observation of Sōichi Kakeya on the set of all subsums of a convergent positive series.

Rate of decay for solutions of viscoelastic evolution equations
Electronic Journal of Differential Equations, 2013 In this article we consider a Cauchy problem of a nonlinear viscoelastic equation of order four. Under suitable conditions on the initial data and the relaxation function, we prove polynomial and logarithmic decay of solutions.

Uranium Doped Gallium Nitride Epitaxial Thin Films
Advanced Electronic Materials, EarlyView.Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained
