In a companion study, we demonstrated that pretreatment of gamma-alumina surface with arsenate enhances uranyl uptake under acidic conditions, where uranyl otherwise sorbs poorly. Here, we examine the local structure and long-range order of the sorption products by using X-ray absorption spectroscopy (XAS) and X-ray diffraction (XRD). Arsenate was chosen for the pretreatment because of its high...

‎let $p$ be a prime with $pgeq 7$ and $q=2(p-1)$‎. ‎in this paper‎ ‎we prove the existence of a nontrivial product of‎ ‎filtration $s+4$ in the stable homotopy groups of spheres‎. ‎this nontrivial‎ ‎product is shown to be represented up to a nonzero scalar by‎ ‎the product element $widetilde{gamma}_{s}b_{n-1}g_{0}in‎ ‎{ext}_{mathcal{a}}^{s+4,(p^n+sp^2+sp+s)q+s-3}(mathbb{z}/p,mathbb{z}/p)$‎ ‎in ...

Abstract The influence of laser shock peening on the surface morphology and microstructure single-crystal CMSX4 nickel-based superalloy was investigated by optical profilometry atomic force microscopy, scanning transmission electron microscopy as well scanning-transmission in high-angle annular dark-field mode. Maps chemical elements distribution laser-affected areas were determined using energ...

We consider the production of a Higgs boson in association with two electroweak vector bosons at hadron colliders. In particular, we examine $\gamma\gamma H$, $\gamma ZH$, $ZZH$, and $W^{+}W^{-}H$ LHC (14 TeV), HE-LHC (27 FCC-hh (100 TeV) Our main focus is to estimate gluon-gluon ($gg$) channel ($gg \to VV^\prime H$) contributions $pp H~(V,V^\prime=\gamma,Z,W)$ compare them corresponding arisin...

the prime graph $gamma(g)$ of a group $g$ is a graph with vertex set $pi(g)$, the set of primes dividing the order of $g$, and two distinct vertices $p$ and $q$ are adjacent by an edge written $psim q$ if there is an element in $g$ of order $pq$. let $pi(g)={p_{1},p_{2},...,p_{k}}$. for $pinpi(g)$, set $deg(p):=|{q inpi(g)| psim q}|$, which is called the degree of $p$. we also set $d(g):...
