Next generation pH responsive isoporous antifouling nanomembranes deriving from block copolymers

Dimitri IVANOV · Martin ROSENTHAL · IOANNIS MOUTSIOS

The present research is focused on design of novel materials for applications in water-permeable or pH-responsive micro-membranes. An in-situ study of these materials under controlled humidity will be performed in which we will monitor swelling of PEO and P4VP blocks. Given that P4VP is hydrophilic only at acidic pH va...

Valentina BELOVA · Julia CZARNECKA · Maciej JANKOWSKI · NIKOO GHANADAN · y 5 más

In-house research on the growth of 2D materials on liquid metal surface within the new european project 2D-Engine.

Adaptive nonlinear learning framework with dynamic representations for scalar-on-function regression

Jiayu Shang · Xiao-Jun Zeng

Continuous functional data, such as biomedical signals and sensor measurements, are increasingly prevalent in modern scientific and industrial applications. Effectively modelling scalar-on-function regression, where scalar responses depend on infinite-dimensional predictors, remains a significant challenge in statistic...

Universal proof theory: Semi-analytic rules and uniform interpolation

Amirhossein Akbar Tabatabai · Raheleh Jalali

In \cite{Craig}, we introduced a syntactically defined and highly general class of calculi known as \emph{semi-analytic}. We then demonstrated that any sufficiently strong (modal) substructural logic with a semi-analytic calculus must satisfy the Craig interpolation property. In this paper, we show that if the calculus...

Sensitizing and inhibiting effects of nitrogen oxides in dimethoxymethane oxidation: Experiments and kinetic modeling

Alessandro Stagni · Steffen Schmitt · Ewald Keksel · Nina Gaiser · y 8 más

Dimethoxymethane (DMM, or OME1) has recently raised significant attention as the archetypal species of the oxymethylene ethers (OME) family, identified as a potential sustainable alternative to diesel fuels. However, so far limited attention has been paid to the sensitizing and inhibiting effects of nitrogen oxides (NO...

Joint-Structural Biology Group (JSBG) BAG proposal for ID29 beamline

Heather PINKETT · Sabine BOTHA · Samuel ROSE · Shibom BASU · y 1 más

The aim of the JSBG BAG proposal for ID29 beamline is to develop new methods for time-resolved serial crystallography experiments at 4th generation source and to study time dependent structural conformation of biological macromolecules that are studies at the ESRF-EMBL-GR Joint Structural Biology Group. Method developm...

Investigating the iron oxidation state in silicate melt using nano-focused synchrotron Mössbauer spectroscopy under deep magma ocean conditi

Xiang LI · Ilya KUPENKO · Edith KUBIK · Lianjie MAN

The redox conditions of the magma ocean on early Earth had a far-reaching impact on the composition and evolution of the silicate mantle and atmosphere. In this study, we propose to investigate the iron oxidation state of silicate melts under metallic-iron saturated conditions, for the first time, reaching pressures an...

On Lichnerowicz sharp distance-regular graphs

Kaizhe Chen · Shiping Liu · Heng Zhang

The first non-zero Laplacian eigenvalue $λ_1$ of a finite graph is bounded below by its minimum Lin--Lu--Yau curvature $κ$. This is a discrete analogue of the classical Lichnerowicz Theorem. A graph with $λ_1=κ$ is called Lichnerowicz sharp. In this note, we give a new proof of the classification of Lichnerowicz sharp...

Powerful Fibonacci polynomials over finite fields

Graeme Bates · Ryan Jesubalan · Seewoo Lee · Jane Lu · y 1 más

Bugeaud, Mignotte, and Siksek proved that the only perfect powers in Fibonacci sequence are 0, 1, 8, and 144. In this paper, we study the polynomial analogue of the problem. Especially, we give a complete characterization of the Fibonacci polynomials that are perfect powers or powerful over finite fields, where there a...
