The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical ...

Nonequilibrium Laser Regulation of the Electronic Structure of the Ni‐Based Electrode for Boosting Nucleophilic Electrooxidation of Alcohols

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports an efficient, simple, low‐cost, and scalable method for overall electrode preparation. Nonequilibrium laser synthesis rapidly yields NiO nanocrystals on which a nickel oxyhydroxide (NiOOH) overlayer is grown in situ. By varying the number of laser pulses, the Ni3+/Ni2+ ratio is precisely tuned, thereby modulating the electronic ...

Cross-cultural study of intensifiers in face-threatening situations: A gender perspective in English and Bahasa Indonesia [PDF]

Training, Language and Culture
Intensifiers play a crucial role in everyday communication, varying in frequency, function, and socio-pragmatic significance across languages. However, gender-based variation in their use remains underexplored. This study examines intensifier usage among

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Pediatric spinal ependymomas: Long‐term surgical outcomes in a cohort of 61 cases

Pediatric Investigation, EarlyView.
Spinal ependymomas are rare in children, with limited long‐term outcome data. In this retrospective study of 61 pediatric patients undergoing surgical resection, gross total resection was achieved in 62.3% and was associated with favorable functional improvement. Recurrence was observed in 31.1% of cases.

A Highly Porous Nanofibrillar PEDOT:PSS Matrix for Beyond‐Surface Precious‐Metal Utilization and Volumetric Electrocatalysis

Small, EarlyView.
Solvent‐assisted crystallization transforms PEDOT:PSS into a conductive nanoporous scaffold that enables volumetric incorporation and utilization of Pt nanoparticles. Unlike surface‐limited Pt only electrodes, the PP–Pt electrode allows ion penetration and bulk catalyst activation, improving precious‐metal utilization and sustaining electrocatalytic ...
