Enhancing Indoor Photovoltaic Efficiency to 37.6% Through Triple Passivation Reassembly and n‐Type to p‐Type Modulation in Wide Bandgap Perovskites

Advanced Functional Materials, EarlyView.
Triple Passivation Treatment (TPT) strategy enables 1.75 eV wide‐bandgap perovskite solar cells (WB‐PSCs) with suppressed halide phase segregation and n‐to‐p type surface transition. The photoluminescence quantum yield increases from 0.5 to 2.1%, indicating reduced non‐radiative losses.

PAMPAS

Proceedings of the 28th International Conference on Scientific and Statistical Database Management, 2016
Mobile participatory sensing could be used in many applications such as vehicular traffic monitoring, pollution tracking, or even health surveying. However, its success dependson finding a solution for querying large numbers of users which protects user location privacy and works in real-time.

Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

Advanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Mobile participatory sensing with strong privacy guarantees using secure probes

GeoInformatica, 2019
Mobile participatory sensing (MPS) could benefit many application domains. A major domain is smart transportation, with applications such as vehicular traffic monitoring, vehicle routing, or driving behavior analysis. However, MPS’s success depends on finding a solution for querying large numbers of smart phones or vehicular systems, which protects ...

Intangible trust requirements - how to fill the requirements trust "gap"? [PDF]

, 2010
Previous research efforts have been expended in terms of the capture and subsequent instantiation of "soft" trust requirements that relate to HCI usability concerns or in relation to "hard" tangible security requirements that primarily relate to security

Mixing Additive and Multiplicative Masking for Probing Secure Polynomial Evaluation Methods

IACR Transactions on Cryptographic Hardware and Embedded Systems, 2018
Masking is a sound countermeasure to protect implementations of block- cipher algorithms against Side Channel Analysis (SCA). Currently, the most efficient masking schemes use Lagrange’s Interpolation Theorem in order to represent any S- box by a polynomial function over a binary finite field.

A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring

Advanced Functional Materials, EarlyView.
This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

Spoiled Onions: Exposing Malicious Tor Exit Relays

, 2014
Several hundred Tor exit relays together push more than 1 GiB/s of network traffic. However, it is easy for exit relays to snoop and tamper with anonymised network traffic and as all relays are run by independent volunteers, not all of them are innocuous.
