Further, the dissolution time was found to correlate with acoustic emissions generated by the bubble cloud during histotripsy insonation. Overall, these results indicate a combination of modeling and high frame rate imaging may provide means to quantify mechanical energy imparted to the tissue due to bubble expansion for histotripsy.When a topological insulator (TI) is brought to the proximity of a ferromagnetic insulator (FMI), the breaking of the time-reversal symmetry may give rise to quantum anomalous Hall effect (QAHE). The physical properties of such TI-FMI systems are greatly affected by the interfacial structures of the components. Here, we report the growth and structural properties of Bi(110) and Bi2Se3thin films on a FMI of Cr2Ge2Te6(CGT) substrate by scanning tunneling microscopy. We observed various defects and impurities on the CGT surfaces, which serve as the preferential sites for initial nucleation and epitaxial growth of Bi(110) thin films. The exposure of the as-grown Bi(110) thin films to Se vapor leads to the formation of polycrystalline Bi2Se3thin films with randomly distributed holes. The structure and composition of the as-prepared Bi2Se3thin films were further confirmed by Raman spectroscopy and x-ray photoelectron spectroscopy. Our work shows that the quality of the CGT crystals is vital for the growth of high-quality TIs on CGT substrates for QAHE.We report a comprehensive evaluation of a full field-of-view (FOV) photon-counting detector (PCD) CT system using phantoms, and qualitatively assess image quality in patient examples. A whole-body PCD-CT system with 50 cm FOV, 5.76 cm z-detector coverage and two acquisition modes (standard 144 × 0.4 mm collimation and ultra-high resolution, UHR 120 × 0.2 mm collimation) was used in this study. Phantom scans were acquired to assess image uniformity, CT number accuracy, noise power spectrum, spatial resolution, material decomposition and virtual monoenergetic imaging (VMI) performance. 7ACC2 cell line Four patients were scanned on the PCD-CT system with matched or lower radiation dose than their prior clinical CT scans performed using energy-integrating detector (EID) CT, and the potential clinical impact of PCD-CT was qualitatively evaluated. Phantom results showed water CT numbers within ±5 HU, and image uniformity measured between peripheral and central ROIs to be within ±5 HU. For the UHR mode using a dedicated sharp kernel, the limiting in-plane spatial resolution was 40 line-pairs/cm, which corresponds to a 125 µm spatial resolution. The full-width-at-half-maximum for the section sensitivity profile was 0.33 mm for the smallest slice thickness (0.2 mm) using the UHR mode. Material decomposition in a multi-energy CT phantom showed accurate material classification, with a root-mean-squared-error of 0.3 mg/cc for iodine concentrations (2 to 15 mg/cc) and 14.2 mg/cc for hydroxyapatite concentrations (200 and 400 mg/cc). The average percent error for CT numbers corresponding to the iodine concentrations in VMI (40-70 keV) was 2.75 %. Patient PCD-CT images demonstrated better delineation of anatomy for chest and temporal bone exams performed with the UHR mode, which allowed the use of very sharp kernels not possible with EID-CT. VMI and virtual non-contrast images generated on a patient head CT angiography exam using the standard acquisition mode demonstrated the multi-energy capability of the PCD-CT system.We report the enhanced performance of multilayer MoS2transistors by AZ®5214E photoresist encapsulation. The MoS2transistors with SiO2bottom-gate dielectrics exhibited an average increase of 4× in the on/off-current ratio and a 50% increase in the field-effect mobility after photoresist encapsulation. The Y-function method further showed a decrease of 87% in the contact resistance and a 30% increase in the intrinsic carrier mobility, suggesting that photoresist encapsulation provides not only n-type doping but also dielectric screening. The Raman spectra of the photoresist-encapsulated MoS2also suggest n-type doping, which may be due to the electropositive hydroxyl groups in the photoresist. The operation of the photoresist-encapsulated MoS2transistors remained stable in ambient air for at least one month. These results demonstrate that simple photoresist encapsulation can be an effective performance booster of MoS2and other transition metal dichalcogenides transistors.Tissue engineering is a branch of regenerative medicine that harnesses biomaterial and stem cell research to utilise the body's natural healing responses to regenerate tissue and organs. There remain many unanswered questions in tissue engineering, with optimal biomaterial designs still to be developed and a lack of adequate stem cell knowledge limiting successful application. Advances in artificial intelligence (AI), and deep learning specifically, offer the potential to improve both scientific understanding and clinical outcomes in regenerative medicine. With enhanced perception of how to integrate artificial intelligence into current research and clinical practice, AI offers an invaluable tool to improve patient outcome.Strain is one of the important factors that determine the photoelectric and mechanical properties of semiconductor materials and devices. In this paper, the scanning transmission electron microscopy multiplication nano-moiré method is proposed to increase the measurement range and sensitivity for strain field. The formation principle, condition, and measurement range of positive and negative multiplication moiré fringes (PMMFs and NMMFs) are analysed in detail here. PMMF generally refers to the multiplication of field of view, NMMF generally refers to the multiplication of displacement measurement sensitivity. Based on the principle of multiplication nano-moiré, Theoretical formulas of the fringe spacing and strain field are derived. Compared with geometric phase analysis of deformation measurements based on high-resolution atom images, both the range of field of view and the sensitivity of displacement measurements of the multiplication moiré method are significantly improved. Most importantly, the area of field of view of the PMMF method is increased by about two orders of magnitude, which is close to micrometre-scale with strain measurement sensitivity of 2 × 10-5.
