Insight into the Growth Mechanism of Mixed Phase CZTS and the Photocatalytic Performance

open access: yesNanomaterials, 2022
In this work, CZTS particles with a mixed phase of wurtzite and kesterite were synthesized by the solvothermal method. The time-dependent XRD patterns, Raman spectra, SEM, and EDS analysis were employed to study the growth mechanism of CZTS.

Dynamic SPECT Assessment of Hepatic Function in Patients With Liver Disease: A Systematic Review and Meta‐Analysis

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Dynamic Single Photon Emission Computed Tomography (dynSPECT) is an advanced functional imaging modality that enables estimation of temporal changes in radiopharmaceutical distribution and physiological function. While dynSPECT has been employed in several clinical applications, it has not been widely applied to liver imaging ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

open access: yesMedicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

.Effect of calcium substitutional doping on the structural and optical properties of kesterite Cu2ZnSnS4 thin films

open access: yesApplied Surface Science Advances
CZTS (Cu2ZnSnS4) kesterite-based solar cells represent promising low-cost and eco-friendly alternatives to traditional solar technologies. While CZTS absorber layers exhibit notable optical advantages, their solar cell efficiency remains below 15 %.

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Obese patient imaging: Potential dose reduction with photon‐counting CT

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Photon‐counting CT (PCCT) offers key advantages over energy integrating detector CT (EID‐CT), especially in low‐dose scans and imaging larger patients. As obesity rates rise, minimizing image noise is critical for diagnostic accuracy.

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

A projection‐domain deep learning approach for respiratory motion correction of myocardial perfusion imaging using a multi‐pinhole solid‐state SPECT

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Myocardial perfusion imagining (MPI) is a nuclear medicine technique used in the assessment of coronary artery disease. Differences in the perfusion of the myocardium at rest and stress and regions of perfusion defects can be indicators of various cardiac disease states. Respiratory motion (RM) can result in the degradation of image
