Surface Reconstruction Induced by Preconditioning in Different Electrolytes Impacts Electrooxidation of Solketal on Multi‐Metal‐Based Catalysts

open access: yesAdvanced Functional Materials, Volume 35, Issue 16, April 18, 2025.
The electrocatalytic activity and stability of CoNiFeCu (1:1:1:0.5) toward glycerol and solketal electrooxidation are strongly impacted by the electrolyte composition used during the catalyst activation. Solketal tends to inhibit oxyhydroxide formation and suppresses Cu leaching, leading to increased activity while also supporting increased production ...

Approximating Holant problems by winding [PDF]

open access: yes, 2013
We give an FPRAS for Holant problems with parity constraints and not-all-equal constraints, a generalisation of the problem of counting sink-free-orientations.

Integration of Cobalt Ferromagnetic Control Gates for Electrical and Magnetic Manipulation of Semiconductor Quantum Dots

open access: yesAdvanced Functional Materials, Volume 35, Issue 14, April 3, 2025.
This work integrates nano‐sized cobalt control gates into a fully‐depleted silicon‐on‐insulator (FDSOI) nanowire architecture, combining electrical and ferromagnetic properties for scalable electron spin qubits. The design enables quantum dot formation at cryogenic temperatures and localized electric dipole spin resonance (EDSR).

Nanoscale Agglomeration Mechanisms of BF‐DPB:BPyMPM Donor–Acceptor Systems for Organic Optoelectronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
The intermolecular and molecule‐substrate interactions and resulting molecular assembly of the OLED and OPV donor and acceptor molecules BF‐DPB and BPyMPM are investigated on different single crystalline substrates using high‐resolution scanning probe microscopy.

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

open access: yesAdvanced Functional Materials, EarlyView.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.
