A universal route to efficient non-linear response via Thomson scattering in linear solids

Gabriel Aeppli, Ji Zhou, Cheng Wang, Junjie Li, Joe Martin Bailey, Min Chen

Non-linear materials are cornerstones of modern optics and electronics. Strong dependence on the intrinsic properties of particular materials, however, inhibits the at-will extension of demanding non-linear effects, especially those second-order ones, to w ...

A hybrid niobium-based oxide with bio-based porous carbon as an efficient electrocatalyst in photovoltaics: a general strategy for understanding the catalytic mechanism

Ulf Anders Hagfeldt, Sining Yun, Cheng Wang

Developing a high-performance catalyst and establishing a catalytic mechanism for understanding the catalytic activity are crucial to new generation photovoltaic technology. In this work, we present a feasible and general route to synthesize a bio-based po ...

Required growth facilitators propel axon regeneration across complete spinal cord injury

Grégoire Courtine, Mark Andrew Anderson, Nicholas David James, Cheng Wang, Sabry Leonardo Barlatey, Michael V. Sofroniew, Zhigang He

Transected axons fail to regrow across anatomically complete spinal cord injuries (SCI) in adults. Diverse molecules can partially facilitate or attenuate axon growth during development or after injury1,2,3, but efficient reversal of this regrowth failure ...

Fast turnaround fabrication of silicon point-contact quantum-dot transistors using combined thermal scanning probe lithography and laser writing

Matthieu Jean Michel Rüegg, Cheng Wang, Nolan Lassaline

The fabrication of high-performance solid-state silicon quantum-devices requires high resolution patterning with minimal substrate damage. We have fabricated room temperature (RT) single-electron transistors (SETs) based on point-contact tunnel junctions u ...

In situ dynamic observations of perovskite crystallisation and microstructure evolution intermediated from [PbI6](4-) cage nanoparticles

Wei Zhang, Feng Liu, Cheng Wang, Lichen Zhao, Rui Zhu, Ke Gao

Hybrid lead halide perovskites have emerged as high-performance photovoltaic materials with their extraordinary optoelectronic properties. In particular, the remarkable device efficiency is strongly influenced by the perovskite crystallinity and the film m ...

Asynchronous Byzantine Agreement with Optimal Resilience and Linear Complexity

Cheng Wang

Given a system with

n > 3t + 1

processes, where

t

is the tolerated number of faulty ones, we present a fast asynchronous Byzantine agreement protocol that can reach agreement in

O(t)

expected running time. This improves the

O(n^2)

expected running ...

A Thrifty Universal Construction

Rachid Guerraoui, Cheng Wang

A universal construction is an algorithm which transforms any sequential implementation of an object into a concurrent implementation of that same object in a linearizable and wait-free manner. Such constructions require underlying low-level universal shar ...

Beyond One Third Byzantine Failures

Rachid Guerraoui, Anne-Marie Kermarrec, Cheng Wang

The Byzantine agreement problem requires a set of

n

processes to agree on a value sent by a transmitter, despite a subset of

b

processes behaving in an arbitrary, i.e. Byzantine, manner and sending corrupted messages to all processes in the system. It ...

Selective degradation of wood lignin over noble-metal catalysts in a two-step process

Paul Joseph Dyson, Chenxu Zhao, Ning Yan, Cheng Wang

Direct conversion of lignin into alkanes and methanol was carried out in a two-step process (hydrogenolysis and hydrogenation) involving initial treatment of white birch wood sawdust with H2 in dioxane/water/phosphoric acid using carbon supported Ru, Pd, R ...
