Pushing the limits of atomic force microscopy: Emerging methods for speed, resolution, and quantitative analysis

Journal of Microscopy, EarlyView.
Abstract Since its introduction 40 years ago, atomic force microscopy (AFM) has transformed nanoscale imaging across the physical and life sciences. In biology, AFM has provided unprecedented insights into nanoscale biomolecular organisation under near‐physiological conditions, revealing structures and interactions inaccessible to many conventional ...

Random forest segmentation and spatial analysis of injected cardiac spheroids in optically cleared myocardium

Journal of Microscopy, EarlyView.
Abstract Accurate quantification of transplanted cardiac spheroids requires three‐dimensional (3D) localisation within intact myocardium, yet this remains technically challenging. Optical clearing and light‐sheet microscopy enable volumetric imaging of injection sites, but automated segmentation is difficult when transplanted spheroids and host tissue ...

The use of thermal imaging to assess heat generation during dental implant bed preparation in the presence of a surgical guide with an incorporated coolant channel

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluates the thermodynamic benefits of including an irrigation fluid channel in the design of surgical guides used for dental implant site drilling. Materials and Methods Two types of guides suitable for hosting artificial bone plates that mimic the mechanical properties of human alveolar bone were designed: a classical ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

Water and hydroxyl on asteroid Bennu: Reconciling remote observations with OSIRIS‐REx sample analysis

Meteoritics &Planetary Science, EarlyView.
Abstract This study investigates the spatial distribution and spectral characteristics of the broad hydration feature near 3 μm across the surface of asteroid (101955) Bennu using OVIRS (OSIRIS‐REx Visible and InfraRed Spectrometer) data. We analyzed multiple global OVIRS data sets obtained at different times throughout the Bennu day, revealing ...
