Surface Ligand Engineering in Quantum Dot Photocatalysis: Mechanisms, Design Principles, and Applications

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
Surface ligands govern quantum dot photocatalysis through thermodynamic band‐edge tuning, kinetic charge‐transfer regulation, and microenvironmental control. Rational ligand engineering, using short‐chain, inorganic, conjugated, or dual‐ligand systems, enables efficient solar fuel production, selective organic transformations, environmental remediation,

Diffusely impaired myocardial perfusion in patients with suspected coronary artery disease: Clinical utility of relative perfusion

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Background In patients with suspected coronary artery disease (CAD), diffusely impaired hyperaemic myocardial blood flow (MBF) may indicate a multivessel epicardial CAD but also impaired coronary microcirculation. We assessed whether relative hyperaemic MBF—that is, the ratio of the lowest to the highest regional hyperaemic MBF—predicts ...

Spleens With Disseminated Lymphoma Exhibit Higher Standardized Uptake Value Maximum, Metabolic Tumor Volumes, and Total Lesion Glycolysis on Fluorine‐18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

Veterinary Radiology &Ultrasound, Volume 67, Issue 6, November 2026.
ABSTRACT Standardized uptake value maximum (SUVmax), metabolic tumor volumes (MTV), and total lesion glycolysis (TLG) are metabolic parameters used to quantify tumors detected on fluorine‐18 fluorodeoxyglucose positron emission tomography/computed tomography (18F‐FDG PET/CT).

Feasibility of multi‐energy CT and fat fraction MRI for characterizing active bone marrow response to pelvic external beam radiation therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Pelvic external beam radiation therapy (EBRT), frequently exposes a substantial fraction of active bone marrow (ABM), leading to radiation‐induced marrow suppression and associated hematologic toxicity. Accurate delineation and quantitative assessment of ABM are therefore essential to enable marrow‐sparing radiotherapy strategies ...

Seeing radiation: Applications of an imaging survey meter in radiation oncology

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background and purpose Radiation shielding surveys require location and evaluation of radiation hotspots in shielding barriers. This process is normally done by using a conventional survey meter and slowly moving the survey meter manually across the face of the barrier.
