Elastomeric Nanocomposite with Solvent‐Free, One Step, In Situ Shear Exfoliation of Graphite to Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...

How to Achieve High Spatial Resolution in Organic Optobioelectronic Devices?

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores how the optoelectronic properties of organic semiconductors impact on the resolution of light‐activated bioelectronic interfaces. Using photovoltage and photocurrent microscopy techniques, the authors show that H2PC/PTCDI heterojunctions enable a resolution down to 6.5 µm due to low carrier mobility along the heterojunction.

High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

open access: yesAdvanced Materials Interfaces, EarlyView.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...

Better Word Embeddings by Disentangling Contextual n-Gram Information [PDF]

open access: yesarXiv, 2019
Pre-trained word vectors are ubiquitous in Natural Language Processing applications. In this paper, we show how training word embeddings jointly with bigram and even trigram embeddings, results in improved unigram embeddings. We claim that training word embeddings along with higher n-gram embeddings helps in the removal of the contextual information ...

Probing for Semantic Classes: Diagnosing the Meaning Content of Word Embeddings [PDF]

open access: yesarXiv, 2019
Word embeddings typically represent different meanings of a word in a single conflated vector. Empirical analysis of embeddings of ambiguous words is currently limited by the small size of manually annotated resources and by the fact that word senses are treated as unrelated individual concepts.

Sustainable Sensors Prepared by Environmentally Benign Means for Improving the Environmental Footprint of Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
A stretchable and bendable resistance sensor made predominantly from sustainable and biodegradable components is conductive courtesy a water soluble self‐doped conjugated polymer. The wearable sensor measures micromovements by changes in its resistance and it can track both human movement and phonation. Abstract Sustainable electronic devices offer the

Learning Semantic Representations for Novel Words: Leveraging Both Form and Context [PDF]

open access: yesarXiv, 2018
Word embeddings are a key component of high-performing natural language processing (NLP) systems, but it remains a challenge to learn good representations for novel words on the fly, i.e., for words that did not occur in the training data. The general problem setting is that word embeddings are induced on an unlabeled training corpus and then a model ...

Aerosol Jet Printing of Superhydrophobic Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Flexible 3D‐Printed Cellulosic Constructs for EMI Shielding and Piezoresistive Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a method for fabricating lightweight, conductive, and compressible 3D‐printed structures from CNFs. By using ion‐seeded 3D printing and cold chemical vapor polymerization, PEDOT/CNF frameworks with electrical conductivity and compressibility are produced.
