Securing a more balanced global economy [PDF]

open access: yes
In this speech, made shortly after the stock market crash of October 1987, President Corrigan identifies imbalances in the U.S. and the world economy that contributed to financial market instability. He emphasizes that the reduction of U.S.

Theories of Everything and Hawking's Wave Function of the Universe [PDF]

open access: yesin The Future of Theoretical Physics and Cosmology, ed. by G.W. Gibons, E.P.S. Shellard and S.J. Rankin, (Cambridge Univ. Press, Cambridge, 2003)., 2002
If a cat, a cannonball, and an economics textbook are all dropped from the same height, they fall to the ground with exactly the same acceleration under the influence of gravity. This equality of gravitational accelerations of different things is one of the most accurately tested laws of physics.

The determinants of urban concentration [PDF]

open access: yes
Urban concentration differs across countries. One determinant of these differences is economic development, which first increases and subsequently decreases urban concentration.

Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Reciprocity as the foundation of Financial Economics [PDF]

open access: yesarXiv, 2013
This paper argues that the fundamental principle of contemporary financial economics is balanced reciprocity, not the principle of utility maximisation that is important in economics more generally. The argument is developed by analysing the mathematical Fundamental Theory of Asset Pricing with reference to the emergence of mathematical probability in ...

Economy vs History - What Does Actually Determine the Distribution of Shops' Locations in Cities? [PDF]

open access: yes
This study examines in which cases economic forces or historical singularities prevail in the determination of the spatial distribution of retail shops. We develop a relatively general model of location choice in discrete space. The main force towards an

Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

Harnessing Interfacial Cl− Ions for Concurrent Formate Production at Industrial Level via CO2 Reduction and Methanol Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...
