Summary: This study investigates the acoustic radiation forces on spherical objects generated by Bessel beams in a viscous fluid. The researchers examine the forces on elastic spheres and shells of different materials using a viscid expression, and compare the results with numerical simulations. The study finds that there is a negative pulling force even when there are positive forces from other sources, but the parameter regions for pulling forces are reduced, especially for small objects. This work contributes to the further study of particle manipulation by acoustic Bessel beams in viscous fluids and guides the experimental realization of acoustic tractor beams.

Summary: Acoustic radiation force and torque can be used for biocompatible, contact-free, and precise translation and rotation of micro-objects. By utilizing the shape asymmetry of an object, a simple standing wavefield is used to trap and rotate micro-objects. The conformal transformation approach is employed to facilitate fast analysis and real-time computer-controlled manipulation. A low-cost, simple rotational tweezing system is built to confirm the theoretical predictions.

Summary: This work presents a model for calculating the acoustic radiation torque on a compressible spheroid, applicable to objects of arbitrary size, shape, and impedance in any incident sound field. By using spheroidal wave expansions to obtain scattering coefficients, the results illustrate the dependence of the radiation torque on the size, aspect ratio, impedance, and orientation of the spheroid with respect to the incident wave field.

Summary: This study focuses on the application of magnetized hybrid nanofluid in engineering and advanced industrial processes, and investigates the effect of suspended nano-size particles on the fluid flow using buoyancy and viscous dissipation. A numerical model of three-dimensional hybrid nanofluid flow is developed, considering the heat transmission phenomenon and the influence of parameters such as magnetic parameter M, slip parameter K, rotation parameter λ, and buoyancy parameter λb. The velocity and temperature distributions are determined using the Runge-Kutta (4th order) method, and the influence of various parameters on the flow behavior is graphically presented. The results are validated numerically and will contribute significantly to the field of fluid mechanics.

Summary: An expression for the acoustic radiation force on a free spherical particle in a viscous fluid subjected to an incident plane wave was derived, considering fluid viscosity, particle elasticity, and the particle's state when suspended in the liquid. Experiments were designed and conducted to compare measured ARFs with theoretical predictions using polystyrene spheres. The analysis showed that ARF increases with pressure amplitude or dynamic viscosity, with maxima or minima depending on dimensionless frequency kR, and good agreement between theoretical and experimental values. This work provides an advanced ARF theory for more accurate real-world predictions.

Summary: With the attributes of being biocompatible, label-free, and contact-free, sound has been widely used to manipulate micro-objects, such as cells, soft matters, and living things, by the acoustic radiation force and torque arising from wave scattering. However, handling irregular surfaces subject to non-orthogonal and inseparable boundary conditions remains a challenge. In this study, a calculation method is proposed based on conformal mapping and separation of variables to solve the acoustic radiation force and torque on an axisymmetric geometry with an irregular cross-section excited by a time-harmonic plane wave. The method is validated by comparisons with full 3D numerical solutions and found to be more efficient.

Summary: This study analyzes the flow pattern and power consumption of mixing highly viscous fluids under vertical acoustic vibration, and investigates the effects of various process parameters on them. It is found that increasing the frequency or amplitude of vibration can expedite the mixing process, leading to improved mixing uniformity and significantly enhancing the effective mixing power. However, the energy absorbed by the fluids is highly nonlinear with respect to the frequency or amplitude of vibration.

Summary: Nanofluids are a new generation of fluids that improve the heat transfer capabilities of conventional fluids. However, current nanofluid models fail to describe fluids with certain microscopic characteristics. This study numerically investigates the laminar two-dimensional heat transfer flow of a micropolar nanofluid containing copper nanoparticles and water through a porous medium over a stretching sheet. The effects of parameters such as micro-rotation, boundary, and suction on velocity, angular velocity, and temperature are analyzed.

Summary: This article discusses the two-dimensional steady laminar boundary layer flow and heat mass transfer caused by a non-Newtonian nanofluid due to a horizontally stretching sheet. By considering various non-dimensional parameters, including convective boundary condition, slip velocity, Brownian motion, thermophoresis and viscous dissipation, numerical values for dimensionless velocity, temperature and nanoparticle concentration are obtained. The distributions of these variables are plotted against important governing factors, and local skin-friction coefficient, Sherwood number and Nusselt number are discussed to further explain the problem.

Summary: This study numerically investigates the stagnation point flow of a copper-water nanofluid across a convective stretching/shrinking cylinder, taking into account the effects of thermal radiation and viscous dissipation. The results demonstrate that for a shrinking cylinder, the skin friction increases while for a stretching cylinder, it decreases. On the other hand, the heat transfer rate exhibits the opposite trend.

Summary: Patient-derived tumor xenograft (PDX)/organoid (PDO) models, driven by cancer stem cells (CSC), are considered the most predictive models for translational oncology and have been extensively used for testing investigational therapies. We have created a biobank of carcinoma PDX-derived organoids (PDXOs) and confirmed their similarity to parental PDXs in genomics, histopathology, and pharmacology. We demonstrate the applications of this PDXO biobank in high-throughput screening, immune therapies, and in vitro/in vivo imaging.

Summary: We developed a simple and convenient genotyping assay using oral swabs for sample preparation, in which PCR coupled with nested invasive reaction and visualisation based on gold nanoparticle probes were performed in a closed tube. This method relies on the single base recognition property of the invasive reaction and allows rapid and accurate detection of CYP2C19*2 and CYP2C19*3 genotypes. The typing results of 20 oral swab samples were consistent with pyrosequencing, indicating the great potential of this method for SNP typing in source-limited regions to guide personalised medicine.

Summary: This paper investigates the method of generating inflow turbulence based on turbulence fluctuation library (TFL) in direct numerical simulation (DNS) of the hypersonic turbulent boundary layer (TBL). The application of the TFL method to the DNS of a supersonic TBL shows successful development to the target TBL downstream, despite significant differences in freestream between the TFL and the target TBL. New thermodynamic fluctuations scaling laws are derived to address the defects of the current TFL method under hypersonic TBL, resulting in more rational and accurate scaling laws. The study also highlights the importance of matching the friction Reynolds number (Re-tau) between the TFL and the target TBL in determining the length of recovery distance.
