Exploring 3D Printing and Electrospinning Technologies for Advanced Porous Membrane Fabrication: A Review

open access: yesAdvanced Materials Technologies, EarlyView.
This paper contrasts electrospinning and 3D printing for porous membrane fabrication, evaluating their evolution, cost, resolution, mechanical traits, and scalability. While 3D printing excels in material diversity and industrial adaptability, electrospinning achieves finer resolution and thermal resilience.

Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

open access: yesAdvanced Materials Technologies, EarlyView.
Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies are employed to stabilize SnO2 upon cycling i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating.

Temperature‐Dependent Voltage Control of Flexible Polymeric Electrochromic Devices for Improved Durability

open access: yesAdvanced Materials Technologies, EarlyView.
The functionality of flexible polymeric electrochromic devices (ECDs) in high‐temperature environments is crucial for long‐term durability. The thermal stability of ECDs based on a poly(3,4‐ethylenedioxythiophene) derivate and Prussian blue is improved by analyzing the temperature‐dependent electrochemical behavior of the electrodes and the ECDs.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

open access: yesAdvanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

open access: yesAdvanced Optical Materials, EarlyView.
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.
