Towards Autonomous Knowledge Creation from Big Data in Smart Cities

open access: yes, 2020
The notion of smart cities is inherently connected with the notion of Big Data. It is Big Data that allows more and more intelligence to be added to our existing urban systems. This intelligence then, at least as a goal, is used to serve the needs of the

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Smart Cities in Europe [PDF]

open access: yesJournal of Urban Technology, 2011
Urban performance currently depends not only on a city's endowment of hard infrastructure (physical capital), but also, and increasingly so, on the availability and quality of knowledge communication and social infrastructure (human and social capital). The latter form of capital is decisive for urban competitiveness.

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

open access: yesAdvanced Science, EarlyView.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

Vulnerability mapping of typhoon-induced flooding based on ECC model

open access: yesSmart Construction and Sustainable Cities
Typhoons lead to meteorological disasters along the coastal region of China. Typhoons induce secondary hazards in cities such as flooding, landslides, vibration of high-rise buildings etc. This paper introduces an improved multi-criteria decision-making (

Smart schools in sentient cities [PDF]

open access: yes, 2014
What makes a city “smart?” And, in a “smart city,” what makes a “smart school?” Designers, researchers and commercial technology companies are increasingly concerned with the development of "smarter cities ...

Toward Long‐Term Reliable Human‐Machine Interaction: A Flexible, Breathable, and Self‐Powered Pressure Sensor System With Firefighting Validation

open access: yesAdvanced Science, EarlyView.
This work develops a breathable potentiometric self‐powered pressure sensor with good wearability, using a non‐woven fabric substrate and hydrogel electrolyte. The sensor is integrated into a five‐channel smart glove to acquire reliable hand motion signals, which are processed by a CNN for identity verification and smart vehicle control in human ...

Waste Heat Recovery in a Transcritical Carbon Dioxide Vapor Compression Cycle with Thermoelectric Generators

open access: yesEnergies
Thermoelectric generators are a great alternative for waste heat energy harvesting in several technological fields. Vapor compression refrigeration systems present great potential for waste heat energy harvesting as they dissipate heat in a condenser/gas

Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly

open access: yesAdvanced Science, EarlyView.
This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.
