Residual Strength Prediction of Chemically Reactive Two‐Phase Nanofluid Flow in a Bingham–Papanastasiou Rheological Theory Using a Morlet‐Based Wavelet Neural Network Approach

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The behavior of nanofluid flow involving a zero‐mass flux condition has received considerable interest because of a realistic scenario. In reality, this condition confines the optimistic accumulation or disappearance of nanoparticles past a sheet, constructing a more physically realistic demonstration through several applications, such as heat

Hip Arthroscopy in Adults Aged 40 or Older Produces Clinically Meaningful Symptom Improvement but Carries a Substantial Risk of Conversion to Total Hip Arthroplasty: A Systematic Review

open access: yesArthroscopy, EarlyView.
Purpose To report conversion rates to total hip arthroplasty (THA), patient‐reported outcome measures, and complication rates in adults aged ≥ 40 years undergoing hip arthroscopy since 2016. Methods MEDLINE, EMBASE, and PubMed were searched from January 2016 to March 2025, and pertinent data were abstracted from eligible studies according to the ...

Structural Allograft Reconstruction for Chronic Proximal Hamstring Avulsion Yields Significant Functional Improvement, Acceptable Satisfaction, but Limited Return to Preinjury Sport Levels

open access: yesArthroscopy, EarlyView.
Purpose To evaluate midterm outcomes of structural allograft reconstruction in patients with chronic proximal hamstring avulsion injuries. Methods This was a retrospective cohort study (minimum 2‐year follow‐up) including patients who underwent allograft surgical reconstruction for proximal hamstring avulsion injuries between 2016 and 2023. The primary

Near‐infrared light‐activated aptamer‐based nanoprobe for spatiotemporally resolved detection of L‐lactate in colorectal cancer

open access: yesBMEMat, EarlyView.
A near‐infrared (NIR) light‐activated “lock‐key” nanodevice is reported for spatiotemporally resolved detection of intratumoral L‐lactate. The system stays silent until deep‐penetrating NIR light remotely unlocks its function, allowing for precise sensing within tumors.

Carbon Coking‐Tolerant Perovskite Catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 for Efficient Methane Dry Reforming

open access: yesCarbon and Hydrogen, EarlyView.
A new perovskite‐type catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 was developed for methane dry reforming, which exhibited 93.1% CH4 and 94.7% CO2 conversion with 100 h stability run and excellent anti‐coking capability, benefited from in situ exsolved Fe‐Ni alloy nanoparticles. ABSTRACT Perovskite with high temperature stability and tunability is a very promising
