Agglomeration of Nanoparticles Inhibits Solvent‐Driven Ligand Stripping

open access: yesAdvanced Materials Interfaces, EarlyView.
This article investigates how solvent quality influences agglomeration and ligand stripping of oleylamine‐coated Fe3O4 nanoparticles using experimental techniques and atomistic molecular dynamics simulations. It demonstrates how poor solvents, such as ethanol, induce nanoparticle agglomeration and hinder ligand stripping through interdigitation.

Can NSEC5 be practical for DNSSEC deployments? [PDF]

open access: yes, 2017
NSEC5 is proposed modification to DNSSEC that simultaneously guarantees two security properties: (1) privacy against offline zone enumeration, and (2) integrity of zone contents, even if an adversary compromises the authoritative nameserver responsible ...

Enabling Additively Manufactured Electronics Through Laser Induced Graphene and Copper Deposition on Fully‐Aromatic Polyimides

open access: yesAdvanced Materials Technologies, EarlyView.
This article introduces a hybrid manufacturing approach to create conductive pathways in additively manufactured fully‐aromatic polyimides. This is enabled through a combination of high‐resolution laser scribing process for fabricating graphene and metallizing it with electrodeposition of copper to further increase conductivity.

Study on Early Compressive Strength of Mortar- and Crumb Rubber-Engineered Cementitious Composites Contain Variation of Cement, Palm Shell Ash and River Sand [PDF]

open access: yesE3S Web of Conferences
Engineered cementitious composite (ECC) is a composite that has better tensile properties and behavior compared to concrete. ECC is usually made from cement, water, silica sand, cementitious material, fiber, and other materials.

Controlled Air Gap Formation between W and TiO2 Films via Sub‐Surface TiO2 Atomic Layer Etching

open access: yesAdvanced Materials Technologies, EarlyView.
Delivering SiH4 and WF6 to a lined array of TiO2 films produces a thin film of tungsten while simultaneously, the underlying TiO2 is removed. When the W‐coated TiO2 structure is exposed to further etching cycles after deposition, TiO2 etching continues vertically and laterally, creating a self‐supported W structure and a vacant air gap.

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.
