Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis

The Canadian Journal of Chemical Engineering, EarlyView.
The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for

Ruxolitinib Pharmacokinetics and Exposure–Toxicity Relationship in Hematologic Malignancies and Immune‐Mediated Diseases: A Prospective Observational Study

Clinical Pharmacology &Therapeutics, EarlyView.
Ruxolitinib pharmacokinetics (PK) has been characterized in clinical trials but remains poorly documented in real‐world practice. This project aimed to investigate ruxolitinib PK in routine clinical practice, identify factors driving its variability, and explore exposure–response relationships to assess the potential role of therapeutic drug monitoring.

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Associations Between Preexisting Depression and Anxiety and Postoperative Outcomes Among Medicare Beneficiaries Undergoing Head and Neck Cancer Surgery

Head &Neck, EarlyView.
ABSTRACT Introduction Depression and anxiety are common in patients with head and neck cancer (HNC), but their impacts on postoperative outcomes after major HNC surgery are not well defined. We evaluated whether preexisting, clinically diagnosed depression or anxiety independently predicted short‐term postoperative outcomes among adults undergoing HNC ...

Occurrence of South American fur seals Arctocephalus australis (Zimmermann, 1783) in San Matías Gulf, Patagonia, Argentina

Latin American Journal of Aquatic Research, 2013
The South American fur seal, Arctocephalus australis (SAFS) population suffered a drastic reduction due to commercial exploitation during the XVIII and XIX centuries. In the last decades a population recovery was detected in the Atlantic region. However,
