Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Foreign exchange reserves in a credit constrained economy [PDF]

International Economics, 2012
cet article traite du rôle des réserves de change en tant qu’épargne de précaution dans un cadre de marché imparfait, dû à la présence de contraintes de crédit déterminées de façon endogène. nous montrons que le coût de détention des réserves est plus élevé en présence de contraintes sur le crédit, en raison de l’effet de levier de la dette ...

Determinants of foreign exchange reserves and the optimal level of foreign exchange reserves in Bosnia and Herzegovina

Bankarstvo, 2023
The research answered the question of what affects BH foreign exchange reserves and what is the lower limit of the optimal level of foreign exchange reserves of the Central Bank of Bosnia and Herzegovina (CBBH). We defined excess foreign exchange reserves as the difference between the balance of foreign exchange reserves and the lower limit of the ...

The Cost of Holding Foreign Exchange Reserves [PDF]

, 2020
Recent studies that have emphasized that the costs of accumulating reserves for self-insurance purposes have overlooked two potentially important side effects. First, the impact of the resulting lower spreads on the service costs of the stock of sovereign debt, which could substantially reduce the marginal cost of holding reserves. Second, when reserve

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

Advanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.
