In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Coenzyme Q as an Antiadipogenic Factor

Antioxidants & Redox Signaling, 2011
Coenzyme Q (CoQ) is not only the single antioxidant synthesized in humans but also an obligatory element of mitochondrial functions. We have previously reported CoQ deficiency in white adipose tissue of ob/ob mice. We sought to determine (i) whether this deficit exists in all species and its relevance in human obesity and (ii) to what extent CoQ could ...

Factorizations that involve Ramanujan’s function k(q) = r(q)r 2(q 2)

Acta Mathematica Sinica, English Series, 2011
Consider the Rogers-Ramanujan continued fraction defined by \[ r= r(q) = \dfrac{q^{1/5}}{1+} \;\dfrac{q}{1+} \;\dfrac{q^2}{1+} \;\dfrac{q^3}{1+ \cdots}, \quad |q|0 \) and \(\eta(\tau) \) denotes the Dedekind eta-function. The left-hand side has the factorization given by \[ \dfrac{1}{r} -1 - r = \left(\dfrac{1}{\sqrt r} - \left( \dfrac{1-\sqrt 5}{2 ...

Q-factor of tuned microstrip resonator

Radioelectronics and Communications Systems, 2016
The paper presents research of quality factor in the micro-mechanically tunable microstrip resonator and its change in response to tuning. In the presented design unloaded quality factor increases about 10% during tuning due to reduction of dielectric loss in substrate’s medium and ohmic loss in metal electrodes.

Factorizations of the groupsG 2 (q)

Archiv der Mathematik, 1985
Let \(G_ 2(q)\) be the (simple) group of Lie type \((G_ 2)\) over the finite field GF(q). The following result is proved. Theorem. Let \(G=G_ 2(q)\) and \(G=AB\) where A, B are proper non-Abelian simple subgroups of G. Then one of the following holds: (1) \(q=4\) and \(A\cong HJ\), \(B\cong U_ 3(4)\); (2) \(q=3^ n\) and \(A\cong L_ 3(q)\), \(B\cong U_ ...

The Q Factor

2018
In this paper I criticize the Chalmers–Jackson position on the commitments of Materialism from a new direction. Unlike my earlier critique, and that of Block and Stalnaker, I here accept for the sake of argument the overall neo-Fregean semantic project that Chalmers and Jackson employ to draw out the alleged a priori commitments of Materialism ...
