Dispersion of biased swimming microorganisms in a fluid flowing through a tube

, 2010
Classical Taylor-Aris dispersion theory is extended to describe the transport of suspensions of self-propelled dipolar cells in a tubular flow. General expressions for the mean drift and effective diffusivity are determined exactly in terms of axial ...

Enhanced Scintillation with Uncorrelated TL and OSL Signals in LiCaAlF6:Eu Nanoparticles Enables Unprecedented Multimodal Radiation Dosimetry

Advanced Optical Materials, EarlyView.
The graphical abstract illustrates the coexistence of independent OSL and TL signals, demonstrating that the material preserves TL information even after complete OSL zeroing, enabling a dual dosimetric readout within the same material. Abstract The development of multimodal dosimeters capable of preserving independent luminescent signals is a ...

Synergistic effect of Mn + Sc additions on the microstructure evolution and mechanical properties of Mg-Gd-Y-Mn-Sc alloy

Journal of Materials Research and Technology, 2022
Mg-Gd-Y-Mn-Sc alloys with different Mn + Sc contents were prepared by hot extrusion and ageing treatment. The effect of Mn + Sc additions on the microstructures, tensile properties, and corresponding strengthening mechanisms of the as-extruded and peak ...

Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

Journal of Medical Radiation Sciences, EarlyView.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).
