Abstract Charge redistribution plays a prominent role in interpreting the intrinsic electrocatalytic mechanism. Establishing quantitative relationship between local charges and electrochemical performance can fundamentally update design philosophies beyond conventional methods. We describe exertion of an external electric field cobalt phthalocyanine (CoPc)/MoS 2 heterojunction to finely manipulate intermolecular charge transfer. The injected (e − ) from CoPc MoS migrate natural S vacancies...

The basal plane of transition metal dichalcogenides (TMDCs) is inert for the hydrogen evolution reaction (HER) due to its low-efficiency charge transfer kinetics. We propose a strategy filling van der Waals (vdW) layer with delocalized electrons enable vertical penetration from collector adsorption intermediate vertically. Guided by density functional theory, we achieve this concept incorporating Cu atoms into interlayers tantalum disulfide (TaS2). d-orbitals interlayered can constitute...

Efficient photocatalysis is important for sustainable energy. Recently, an unconventional photocatalyst based on intrinsic plasmon, called plasmonic (IPP), seems promising higher efficiency in hydrogen evolution. This catalyst to benefit from the advantages of visible light absorption, plasmon-assisted hot carrier generation, and good catalytic stability over conventional semiconductor photocatalysts. In this work, we report relative evolution under irradiation a family IPP alkaline earth...

Molecular functionalization has been intensely studied and artificially constructed to advance various electrocatalytic processes. While there is a widely approved charge-doping effect, the underlying action for reactant distribution/transport remains long neglected. Here an on-chip microdevice unravels that proton enrichment effect at prototypical methylene blue (MB)/MoS2 interfaces rather than charge doping contributes hydrogen evolution reaction (HER) activity. Back-gated...

In the U.S., carbon emissions escalated with patent applications until Greenhouse Gas Reporting Program (GHGRP) mandated firms to disclose emissions. this study, we show that, post-GHGRP, a greater amount of inefficient CO2 produce significantly more low-carbon patents (as classified by Cooperative Patent Classification system as well our text-based keyword search method), which in turn reduces and increases market value. We provide possible internal external channels for corporate...

This study examines that the institutional investors rollover index options and futures contracts when their nearby-month positions exhibit higher unrealized losses as expiration date approaches. Utilizing trader-type identified account-level data, we perform Regression Discontinuity Design (RDD) analysis by excluding market making possible hedging trading volume using 2008 Taiwanese presidential election an exogenous political uncertainty. We discover investors, both foreign domestic,...

This study examines potential spoofing tactics by analyzing comprehensive order and transaction data of index options futures. We find that prices go up (down) after revisions aggressive limit buy (sell) orders. These improvements in result from the synchronous execution opposite-side orders at better prices, consistent with tactics. rule out alternative explanations for our findings: submission equilibrium chasing scenario. employ Dynamic Price Banding Mechanism, imposed to spoofing, as a...

We evaluate the impact of 2008 Apex Oil court decision that made creditors some corporations financially liable for environmental damages caused by specific pollutants. reduced circumstances under which liabilities were dischargeable in Chapter 11, generated financial incentives firms near bankruptcy to pressure their reduce emissions those discover lowered bond prices, widened loan spreads, and corporate pollution among (a) release chemicals covered (b) are close 11 hence likely be affected...
