Global Engagement and Returns Volatility [PDF]

open access: yes, 2015
This paper finds that a greater reliance on foreign market sales increases the volatility of firms’ stock returns, using high-frequency data for publicly listed Japanese manufacturing firms over the period 2000–10. The two margins of global engagement we

Dual‐Site Ru Single‐Atoms and RuP Nanoclusters on N, P, and B Co‐Doped Porous Carbon for Efficient Alkaline HER and AEM Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Cross‐Layer Molecular Design for Coherent Interface Passivation in Rigid and Flexible Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A cross‐layer passivation strategy employing molecularly designed thiazol‐5‐ylmethanamine hydrochloride (TMACl) enables coherent defect regulation at the SnO2/perovskite interface, stabilizes both layers, promotes phase‐pure α‐FAPbI3 formation, and enhances charge extraction, delivering PCEs of 26.44% in rigid and 24.72% in flexible perovskite solar ...

Corporate financing and macroeconomic volatility in the European union [PDF]

open access: yesInternational Economics and Economic Policy, 2010
This paper investigates the impact of corporate financing patterns in the European Union (EU) on macroeconomic volatility. We examine macroeconomic data for eight EU countries. We find that during the period 1990 through 2005 bank financing was positively associated with volatility in GDP, consumption and investment.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
