Long Term Consequences of Natural Resource Booms for Human Capital Accumulation [PDF]

open access: yes
Tight labour markets driven by resource booms could increase the opportunity cost of schooling and crowd out human capital formation. For oil producing economies like the Province of Alberta, the OPEC oil shocks of 1973 to 1981 may have had an adverse ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Borrowing, resource transfers, and external shocks to developing countries : historical and counterfactual [PDF]

open access: yes
Since the late 1970's the buildup and servicing of external debt has dominated the economic situation in many developing countries. This paper gathers some statistical evidence on the magnitude of lending and repayment and on the question of whether ...

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

THE IMPACT OF GATT ON INTERNATIONAL TRADE: EVIDENCE FROM STRUCTURAL BREAK ANALYSIS [PDF]

open access: yes
In this study we test for structural changes in international trade patterns of 77 countries over the post-WWII period, to examine if they experienced a substantial increase in their trade ratios following major GATT rounds such as the Kennedy Round, or ...

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Volatility Spillovers in Emerging Markets: Oil Shocks, Energy, Stocks, and Gold

open access: yesEnergies
This paper extends the literature on the relationship between oil price shocks and financial markets by examining the effect of supply and demand oil shocks on emerging energy markets, stocks of emerging markets, and gold and exploring the impact of ...

Vehicle-to-Grid - What is the Benefit for a Sustainable Mobility? [PDF]

open access: yes
The demand for vehicles in industrialised countries is dropping and the growth rate in developing countries is slowing down rapidly. Driver of this evolution is evidently the current crisis but also the expectation that in the long run oil will not be ...

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...
