Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

A Simple Test of Momentum in Foreign Exchange Markets [PDF]

This study proposes a new method for testing for the presence of momentum in nominal exchange rates, using a probabilistic approach. We illustrate our methodology estimating a binary response model using information on local currency / US dollar exchange

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures

Advanced Functional Materials, EarlyView.
3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Identification through technical analysis : A study of charting and UK non-professional investors [PDF]

, 2013
The usefulness of technical analysis, or charting, has been questioned because it flies in the face of the 'random walk' and tests present conflicting results.

Bimetallic Nanoparticles as Cocatalysts for Photocatalytic Hydrogen Production

Advanced Functional Materials, EarlyView.
Recent developments have introduced bimetallic nanoparticles as effective cocatalysts for photocatalytic systems. This review explores the rapidly expanding research on bimetallic cocatalysts for photocatalytic production of hydrogen, emphasizing the creation of carrier‐selective contacts, localized surface plasmon resonance effects, methodologies for ...

Symmetry Enhanced Unconventional Spin Current Anisotropy in a Collinear Antiferromagnet

Advanced Functional Materials, EarlyView.
Spin‐orbit torques (SOTs) are investigated in epitaxial FeSn, a topological antiferromagnet with kagome lattice symmetry. Combining experimental and theoretical approaches, the study identifies a six‐fold conventional damping‐like spin‐orbit torque (DL SOT), along with the coexistence of both six‐fold and uniaxial unconventional field‐like torque (FL ...

Building on momentum from the global campaigns: an exploration of factors that influenced prioritization of stillbirth prevention at the national level in Uganda

Globalization and Health, 2021
Background Of the close to 2.6 million stillbirths that happen annually, most are from low-income countries where until recently policies rarely paid special attention to addressing them.
