2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

The Impact of the QFIIs Deregulation on Normal and Abnormal Information Transmission Between the Stock and Exchange rates in Taiwan [PDF]
This investigation adopts the Correlated Bivariate Poisson GARCH with Jump and Diffusion Volatility Spillover (CBP-GARCH-JDSV) model to determine whether the Qualified Foreign Institutional Investors (QFIIs) deregulation in Taiwanese stock markets ...

Arbitrage pricing theory: Evidence from an emerging stock market
Employing the data for the period before the Asian Financial Crisis 1997-1998, between Jan 1987 and Dec 1996 under the light of the methodology proposed by Fama and McBeth (1973), the research investigates the relationship between the stock returns in ...

We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Stock Prices and Exchange Rates in the EU and the United States: Evidence on their Mutual Interactions (in English) [PDF]
This paper investigates the nature of the causal relationships among stock prices and effective exchange rates in four old EU member countries (Austria, France, Germany, and the UK), four new EU member countries (Czech Republic, Hungary, Poland, and ...

A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

The Dynamic Relationship between Stock Prices and Exchange Rates: evidence for Brazil [PDF]
This paper studies the dynamic relationship between stock prices and exchange rates in the Brazilian economy. We use recently developed unit root and cointegration tests, which allow endogenous breaks, to test for a long run relationship between these ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with
