Adaptive Diffusion Models for Sparse-View Motion-Corrected Head Cone-beam CT [PDF]

arXiv
Cone-beam computed tomography (CBCT) is a imaging modality widely used in head and neck diagnostics due to its accessibility and lower radiation dose. However, its relatively long acquisition times make it susceptible to patient motion, especially under sparse-view settings used to reduce dose, which can result in severe image artifacts.

Elastomeric Nanocomposite with Solvent‐Free, One Step, In Situ Shear Exfoliation of Graphite to Graphene

Advanced Materials Interfaces, EarlyView.
This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...

Excited‐State Intramolecular Charge‐Transfer Dynamics in 4‐Dimethylamino‐4′‐cyanodiphenylacetylene: An Ultrafast Raman Loss Spectroscopic Perspective

ChemPhotoChem, Volume 6, Issue 12, December 2022., 2022
The D‐π‐A compound 4‐dimethylamino‐4′‐cyanodiphenylacetylene (DACN‐DPA) exhibits intramolecular charge transfer (ICT) upon photoexcitation. Ultrafast Raman Loss Spectroscopy (URLS) measurements show distinct spectral and temporal dynamics of C≡C and C=C vibrational modes in MeCN and n‐hexane, revealing that ICT is strongly coupled to the structural ...
