Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation
Advanced Functional Materials, EarlyView.It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Random key pre-distribution with transitory master key for wireless sensor networks [PDF]
Proceedings of the 5th international student workshop on Emerging networking experiments and technologies, 2009 Many Wireless Sensor Networks (WSNs) employ security schemes based on the symmetric encryption, which requires the establishment and management of cryptographic keys. This paper presents a new key management scheme based on Random Key Pre-Distribution. The novelty of the proposed approach is the introduction of a keyed transformation with a Transitory ...

A resilient key predistribution scheme for multiphase wireless sensor networks [PDF]
, 2009 In wireless sensor networks, sensor nodes eventually die due to battery depletion. Wireless sensor networks (WSNs) in which new nodes are periodically redeployed with certain intervals, called generations, to replace the dead nodes are called multi-phase
