Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

The abundances of hydrocarbon functional groups in the interstellar medium inferred from laboratory spectra of hydrogenated and methylated polycyclic aromatic hydrocarbons

open access: yes, 2013
Infrared (IR) absorption spectra of individual polycyclic aromatic hydrocarbons (PAHs) containing methyl (-CH3), methylene (>CH2), or diamond-like *CH groups and IR spectra of mixtures of methylated and hydrogenated PAHs prepared by gas phase ...

Concentration, source identification, and exposure risk assessment of PM2.5-bound parent PAHs and nitro-PAHs in atmosphere from typical Chinese cities

open access: yesScientific Reports, 2017
Sixteen parent PAHs and twelve nitro-PAHs were measured in PM2.5 samples collected over one year (2013–2014) at nine urban sites in China. During the sampling period, concentrations of individual nitro-PAHs were one or two orders of magnitude lower than ...

Synthesis and Application of Conductive Pitch‐Based Porous Carbon for Energy Storage Device as a Supercapacitor

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...

Portopulmonary hypertension practice patterns after liver transplantation

open access: yesLiver Transplantation, EarlyView., 2022
Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

Long‐Term Outcomes of Reduced‐Intensity Conditioning Hematopoietic Stem Cell Transplantation for Patients With Systemic Sclerosis With Impaired Cardiac Function

open access: yesArthritis &Rheumatology, EarlyView.
Objective High‐intensity conditioning autologous hematopoietic stem cell transplantation (AHSCT) is standard of care for patients with advanced systemic sclerosis (SSc). The role of reduced‐intensity conditioning (RIC) before AHSCT in this population remains unclear.

Impact of Evolving Treatment Patterns on Interstitial Lung Disease Progression in Systemic Sclerosis Using the European Scleroderma Trials and Research Database

open access: yesArthritis &Rheumatology, EarlyView.
Objective The treatment landscape for systemic sclerosis‐associated interstitial lung disease (SSc‐ILD) has evolved with increasingly available immunosuppressive therapies (ISTs) and antifibrotic treatments. However, their real‐world use remains unclear.

The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...

Search for PAHs in the Perseus molecular cloud with the Green Bank Telescope

open access: yes, 2014
Polycyclic Aromatic Hydrocarbons (PAHs) are believed to be the small-size tail of the interstellar carbonaceous dust grain population. Their vibrational emission is the most widely accepted source of the aromatic near-infrared features, and their ...
