Advanced Functional Materials, EarlyView.We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...

Authentication for Pervasive Computing
, 2004 Key management is fundamental to communications security, and for security in pervasive computing sound key management is particularly difficult. However, sound key management itself depends critically on sound authentication. In this paper we review current notions of entity authentication and discuss why we believe these notions are unsuitable for ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies
Advanced Functional Materials, EarlyView.Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Advanced Functional Materials, EarlyView.Atomic layer deposition is used to conformally surface engineer polymeric membranes to fabricate inorganic–organic hybrid membranes. These membranes have exceptionally strong attraction toward water even in high oil containing emulsions, which leads to an extremely strong hydration layer at the interface.

Pervasive Computing and Space [PDF]
, 2002 Changes between Accessibility space and Physical space is a major factor in the “pervasive computing scenario”. An example of this type of change, drawn from the maritime domain, is presented. The case is used to suggest concepts and notations for understanding the change. Finally, I argue that skills developed for adapting traditional stationary signs

The Future of Pervasive Health
IEEE Pervasive Computing, 2017 During the May 2016 Pervasive Health Conference Workshop, participants identified five general themes related to pervasive health solutions that must be addressed: technological challenges and opportunities, adoption and adherence, open data, methods and ethical issues, and education. Here, the authors discuss each of these themes in more detail.
