The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

Angewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.

Defect‐Guided Assembly of Aperiodic and Flexible Metal–Organic Frameworks From Pre‐Formed Cages

Angewandte Chemie, EarlyView.
A cage‐directed strategy is used to program topologically correlated defects and induce aperiodicity in HKUST‐1‐type MOFs. A missing carboxylate group in the linker drives the formation of Cu‐vacancy domains, while Rh(II) cages spatially confine these defects.

A Comprehensive 19F NMR Framework for Fragment‐Based Drug Discovery: The Validated Screening Library OpenFL600 and Efficient Affinity Ranking by CSAR

Angewandte Chemie, EarlyView.
NMR screening is a powerful method for hit detection in drug‐discovery. We designed and validated the OpenFL600 19F$^{19}{\rm F}$ NMR library to probe diverse targets, including RNA, GPCRs, kinases, and proteases. This library yields target‐specific ligands without generating promiscuous binders.

Existence results for Robin problems involving p(x)-Laplacian-like operators with convection term

Demonstratio Mathematica
This paper studies the existence of solutions for Robin problems involving p(x)-Laplacian-like operators which arise from capillarity phenomena. When we only consider the convective term, due to the lack of a variational structure, the well-known ...

MIXED BOUNDARY VALUE PROBLEM FOR A QUARTER-PLANE WITH A ROBIN CONDITION [PDF]

Journal of Sciences, Islamic Republic of Iran, 2002
We consider a mixed boundary value problem for a quarter-plane with a Robin condition on one edge. We have developed two procedures, one based on the advanced theory of dual integral equations and the other, in our opinion simpler technique, relying on ...

Entropy solutions for nonlinear elliptic anisotropic problem with Robin boundary condition

Le Matematiche, 2013
We study a Robin boundary value problem of nonlinear elliptic anisotropic type. We prove the existence and uniqueness of entropy solutions for $L^{1}$-data, via the existence and uniqueness of weak solution.

Numerical methods of the fractional advection-dispersion equation with Robin boundary condition

四川大学学报. 自然科学版, 2018
In this paper, we study the practical numerical methods to solve the fractional advection-dispersion equation with Robin boundary condition. We propose an implicit finite difference scheme based on the shifted Grünwald formula to discretize Riemann ...

On some nonlinear potential problems

Electronic Journal of Differential Equations, 1999
The degree theory of mappings is applied to a two-dimensional semilinear elliptic problem with the Laplacian as principal part subject to a nonlinear boundary condition of Robin type. Under some growth conditions we obtain existence.

Direct and inverse Robin-Regge problems

Electronic Journal of Differential Equations, 2017
The Sturm-Liouville equation is considered on a bounded interval with a Robin boundary condition at the left end and a generalized Regge condition at the right end.
