Multifunctional Gold Nanocluster‐Based PROTAC System for Targeted Degradation of Phosphorylated Tau and Modulation of Neuroinflammation in Alzheimer's Disease

Advanced Functional Materials, EarlyView.
We present a novel proteolysis‐targeting chimera (PROTAC) system conjugated to lipoic acid gold nanoclusters (PLANC), designed to degrade pTau, regulate inflammatory signaling, and effectively traverse the blood‐brain barrier (BBB). PLANC degraded pTau at various phosphorylation sites, with mechanistic studies confirming proteasome‐mediated degradation

Onboard attitude determination for a small satellite

, 1996
A system for attitude and rate estimation for a small satellite is described. The estimates are used for onboard attitude control and the precision requirements are limited. An important feature of the effort is, however, the ability of the system to handle multiple sensor faults. Presented are results from the Danish Ørsted micro satellite.

Validation of Astrodynamic Formation Flying Models Against SPACE-SI Experiments with Prisma Satellites

, 2012
In this paper several astrodynamical formation flying models are assessed against the experimental results derived from the SPACE-SI formation flying experiments performed in September 2011 with the OHB Sweden developed Prisma satellites Mango and Tango.

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

Advanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Atomized Oxidative Polymerization as a 3D Printing Platform for Binder‐Free, Bulk Conductive Polymer Architectures

Advanced Functional Materials, EarlyView.
Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

Advanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.
