Metal‐Organic Framework Embedded Electrospun Fibrous Membranes‐Based Hybrid Nanogenerators with Hierarchical Modified Polyamide Films for Mechanical Energy Harvesting and IoT Applications

open access: yesAdvanced Functional Materials, EarlyView.
Hybrid nanogenerator (HNG) based on a zinc‐metal‐organic framework‐loaded fibrous film integrated with a hierarchically modified nylon film having micropatterns and micropores is fabricated via an electrospinning technique, and its electrical properties are optimized. The HNGs are incorporated into wearable garments and automobile systems for practical

Experiments with a Layered Transmission Scheme over the Internet

open access: yes, 1997
Combining hierarchical coding of data with receiver-driven control appears to be an attractive scheme for the multicast transmission of audio/video flows in a heterogeneous multicast environment such as the Internet. However, little experimental data is available regarding the actual performance of such schemes over the Internet.

Quantum Dots and Perovskites‐Based Physically Unclonable Functions for Binary and Ternary Keys via Optical‐to‐Electrical Conversion

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates optoelectronic PUFs that improve on traditional optical and electrical PUFs. The absorber materials are randomly coated through spray coating, ligand exchange, and dynamic spin coating. Incident light generates wavelength‐dependent binary multikey and enhances security ternary keys, approaching near‐ideal inter‐ and intra ...

Multi-layered security in the Internet of the Things

open access: yes, 2014
It is well discussed and understood that there is still a need for suitable security for the Internet of Things. It is however still not clear how existing or emerging security paradigms can be effectively applied to a network of constrained nodes in a lossy communications environment.

Metal‐Organic Nanosheet Gels: Hierarchically Porous Materials for Selective Loading and Differential Release

open access: yesAdvanced Functional Materials, EarlyView.
A suspension of metal‐organic nanosheets was centrifuged to form self‐healing gels with a hierarchically porous structure. The prepared gels were used to selectively capture small molecules from solutions and differentially release them based on their size and charge. Abstract Metal‐organic nanosheets (MONs) are intrinsically porous 2D materials with a

Printing Nacre‐Mimetic MXene‐Based E‐Textile Devices for Sensing and Breathing‐Pattern Recognition Using Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a Ti3C2Tx MXene/WPU nacre‐mimetic nanomaterial as a printable ink for direct‐write printing onto textiles‐based sensors. The resulting wearable device demonstrates high sensitivity, biocompatibility, and mechanical strength. Furthermore, NFC‐enabled humidity sensor produces time‐series data, which informs a machine learning ...
