Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

An Improved Hash Function Based on the Tillich-Zémor Hash Function [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem.

Incompressible strips in dissipative Hall bars as origin of quantized Hall plateaus

open access: yes, 2004
We study the current and charge distribution in a two dimensional electron system, under the conditions of the integer quantized Hall effect, on the basis of a quasi-local transport model, that includes non-linear screening effects on the conductivity ...

Syndrome Based Collision Resistant Hashing [PDF]

open access: yes, 2008
Hash functions are a hot topic at the moment in cryptography. Many proposals are going to be made for SHA-3, and among them, some provably collision resistant hash functions might also be proposed. These do not really compete with "standard" designs as they are usually much slower and not well suited for constrained environments.

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

On the power of memory in the design of collision resistant hash functions [PDF]

open access: yes, 1993
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on “fingerprinting”. This paper proposes a new efficient class of hash functions based on a block cipher that allows for a tradeoff between security and speed.
