Bartholdi zeta functions for periodic simple graphs [PDF]

open access: yes, 2008
The definition of the Bartholdi zeta function is extended to the, case of infinite periodic graphs. By means of the analytic determinant for semifinite von Neumann algebras studied by the authors in [7], a determinant formula and functional equations are

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

open access: yesAdvanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

open access: yesAdvanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Vacuum Energy for Generalized Dirac Combs at T = 0

open access: yesFrontiers in Physics, 2019
The quantum vacuum energy for a hybrid comb of Dirac δ-δ′ potentials is computed by using the energy of the single δ-δ′ potential over the real line that makes up the comb.

Linear law for the logarithms of the Riemann periods at simple critical zeta zeros [PDF]

open access: yes, 2006
Each simple zero 1/2 + iγn of the Riemann zeta function on the critical line with γn > 0 is a center for the flow s˙ = ξ(s) of the Riemann xi function with an associated period Tn. It is shown that, as γn →∞, log Tn ≥ π/4 γn + O(log γn).

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.
