Published: October 2023

AbstractCommonly used isotonic arthroscopic irrigation fluids, such as normal saline or lactated Ringer's, were initially formulated for intravenous administration so they do not replicate the physiologic properties of healthy synovial fluid. Synovial fluid plays an important role in regulating joint homeostasis such that even transient disruptions in its composition and physiology can be detrimental. Previous studies suggest that hyperosmolar solutions may be a promising alternative to traditional isotonic fluids. This manuscript sought to systematically review and synthesize previously published basic science, translational, and clinical studies on the use of hyperosmolar arthroscopic irrigation fluids to delineate the optimal fluid for clinical use. A systematic literature search of MEDLINE/PubMed and Embase databases was performed in accordance with Preferred Reporting Items for Systemic Reviews and Meta-analyses (PRISMA) guidelines. The search phrases were: (“cartilage” AND “hyperosmolar”); (“arthroscopy” OR “arthroscopic” AND “hyperosmolar”). The titles, abstracts, and full texts were screened for studies on hyperosmolar solutions and articular cartilage. Study quality was assessed, and relevant data were collected. A meta-analysis was not performed due to study heterogeneity. A risk of bias assessment was performed on the included translational and clinical studies. There were 10 basic science studies, 2 studies performed in translational animal models, and 2 clinical studies included in this review. Of the basic science studies, 7 utilized a mechanical injury model. The translational studies were carried out in the canine shoulder and equine stifle (knee) joint. Clinical studies were performed in the shoulder and knee. Multiple basic science, translational, and clinical studies highlight the short-term safety, cost-effectiveness, and potential benefits associated with use of hyperosmolar solutions for arthroscopic irrigation. Further work is needed to develop and validate the ideal formulation for a hyperosmolar irrigation solution with proven long-term benefits for patients undergoing arthroscopic surgeries.

Abstract
Background The concept of robotic microsurgery is becoming increasingly known as several robotic systems tailored to the specific needs of microsurgery are being introduced. Training with these devices is essential to draw conclusions about their potential clinical utility. This study describes the training and learning curve of experienced microsurgeons and complete novices using such a robotic surgical system in combination with an exoscope.
Methods Four experienced microsurgeons and three complete novices performed a total of 62 manual and robot-assisted anastomoses. The time for anastomosis completion and surgeon's satisfaction with the anastomosis and with the robotic system were recorded. The anastomoses' quality was assessed using the Structured Assessment of Microsurgery Skills (SAMS) and the Anastomosis Lapse Index (ALI). The Rapid Entire Body Assessment (REBA) was used for ergonomics evaluation.
Results All expert microsurgeons and novices improved their performance during training. The average anastomosis time decreased significantly, while satisfaction with the anastomosis and robotic system increased significantly over time. Multiple SAMS score parameters increased significantly throughout robotic but not manual training and the ALI score demonstrated more errors in the manual group. The REBA score displayed a significantly lower risk for musculoskeletal disorders in the robotic group.
Conclusion Currently, the first clinical applications of robotic surgical systems specifically designed for microsurgery are being reported. The introduction of such systems into clinical practice can be expected to have a steep learning curve, as demonstrated in our study. Meanwhile, robotic systems for microsurgical procedures may hold great potential for improvement of surgical quality and ergonomics.

Published: October 2023

Nanosheets of transition metal dichalcogenides with prospects of photocatalysis and optoelectronics applications have significant potential in device fabrication due to their low-cost production and easily controllable morphology. Here, non-degenerate pump-probe differential transmission studies with varying pump-fluence have been carried out on single-phase 2H–MoSe2 and mixed-phase 1T/2H–MoSe2 nanosheets to characterize their excited carrier dynamics. For both the samples, the differential probe transmission data show photo-induced bleaching at earlier pump-probe delay followed by photo-induced absorption unveiling signatures of exciton-state filling, exciton trapping, defect-mediated photo-induced probe absorption and recombination of defect bound excitons. The exciton trapping and photo-induced absorption by the trapped-carriers are estimated to occur with time constant of ∼430 to 500 fs based on multi-exponential modelling of the differential transmission till pump-probe delay of ∼3.5 ps. Biexponential modeling of the subsequent slow-recovery of the negative differential transmission at pump-probe delay ≳3.5 ps reveals that the exciton recombination happens via two distinct decay channels with ∼25 to 55 ps (τ1) and ≳1 ns (τ2) time constants. Pump-fluence dependent reduction in τ1 and further modelling of exciton population using higher order kinetic rate equation reveals that the two-body exciton-exciton annihilation governs the exciton recombination initially with a decay rate of ∼10−8 cm3s−1. The detailed analysis suggests that the fraction of total excitons that decay via long decay channel decreases with increasing exciton density for 2H–MoSe2, in contrast to 1T/2H–MoSe2 where the fraction of excitons decaying via long decay channel remains constant.
Diffusion and thermodiffusion of the ternary system polystyrene + toluene + cyclohexane
Authors: Sommermann D. , Köhler W. 
Published: October 2023

We have studied diffusion and thermodiffusion in the ternary system polystyrene + toluene + cyclohexane over the entire composition range of the binary solvent toluene + cyclohexane and for polymer concentrations up to 0.1 mass fractions by multi-color optical beam deflection. The polystyrene molar masses were 4.88 and 17.90 kg/mol. The inversion problem of the contrast factor matrix could be avoided by reasonable a priori assumptions about the diffusion eigenvectors. The fast mode of the bimodal dynamics is attributed to the interdiffusion of the two solvents at constant polymer concentration, whereas the slow mode is due to the diffusion of the polymer with respect to the binary solvent. The amplitude of the fast mode vanishes in the pure toluene and the pure cyclohexane limits of the mixed solvent. The amplitude of the slow mode increases with polymer concentration. The composition and temperature dependence of the slow diffusion eigenvalue, the hydrodynamic correlation length, and the Soret coefficient of the polymer reflect the transition from a good to a theta solvent with increasing cyclohexane content and with decreasing temperature. Due to cross diffusion, cyclohexane reverses its migration direction between the fast and the slow mode, leading to a positive thermodiffusion but a negative Soret coefficient. The polymer thermodiffusion coefficients during the slow mode vary by approximately a factor of two, depending on the solvent composition. Rescaling with the solvent viscosity collapses all data onto a single master curve with an extrapolated value of ηDT ≈ 6 × 10−15 Pa m2 K−1 in the dilute limit. This value is well known from various other binary polymer/solvent mixtures.

Abstract
In this work, long-time operation of a dielectric barrier discharge (DBD) characterized by a single thin dielectric was investigated. The discharge was operated under nitrogen at atmospheric pressure in a typical filamentary regime. Electrical measurements were performed, i.e. applied voltage, current and charge were retrieved. The Lissajous figure method combined with an equivalent circuit of the DBD was used to calculate the dissipated power, estimate the gas gap voltage

as well as the capacitances of the discharge cell. The results over a one-hour operation indicated that the total dissipated power remained constant, but a decrease of the gas gap voltage with an increase of the charge deposited was also depicted. For the capacitances, both dielectric and cell capacitances variations were studied from the Lissajous figures. The dielectric capacitance showed a voltage dependency over half a period of applied voltage.

Abstract
The use of electrolyte-gated transistors (EGTs) as sensors can be an advantageous alternative for the detection of anionic molecules due to their capability to detect various ions in solution. In this study, we explore the potential of EGTs as analytical tools for detecting anionic molecules, utilizing a copper phthalocyanine-3,4′,4″,4‴-tetrasulfonic acid tetrasodium salt (CuTsPc) solution as a proof of concept. The results demonstrate the EGT’s capacity in detecting CuTsPc in an aqueous solution, which molecule dissociates into sodium ions (Na+) and CuPc(SO3
−)4 ions, leading to high ionic conductivity and the formation of electrical double layers (EDLs). Varying the concentration of the molecule induced alterations in the EDLs, exhibiting good linearity and sensitivity in the transconductance, and a detection limit of 6.0 × 10−8 mol l−1. Transistors employing the CuTsPc solution as electrolyte operated at low voltages and performed better than water-gated transistors (W-GTs). The transconductance (gm
) value for EGTs using CuTsPc solution reached 1.93 mS, while for W-GTs it was around 0.10 mS. Thus, the CuTsPc solution not only serves as a target-molecule in sensor measurements, but also demonstrates potential as an electrolyte in EGTs, thereby assuming a dual role within the device. The main advantage of the EGTs as an analytical tool is their use as a multiparameter device that enables the detection of the analytes using different phenomena that occur at the EDLs interface and which, consequently, changes the device’s performance.

Published: October 2023

Abstract
Aiming at the complexity of the rolling bearing operation state in actual working conditions and the limitation of the feature extraction capability of single-scale model, this paper proposes a fault diagnosis method based on two-channel adaptive deconvolution and transformer module (TADAT). First, a frequency domain dataset is built and multiscale feature information is extracted using two-channel adaptive deconvolution at the beginning stage of the model; the global features of the signal are further extracted by combining them in series with the transformer (multi-head attention). Next, the loss function is optimized by introducing a regularized loss function with label smoothing and L2 regularization penalty term. Finally, the model is validated against an open-source dataset and operating condition data collected from an unbalanced bearing load test bed with an accuracy of over 98.5%. The model also maintains high accuracy under noisy samples. The test shows that the rolling bearing service condition monitoring method based on TADAT feature extraction model proposed by this method is characterized by simple model structure, high diagnostic accuracy and strong generalization performance, which provides a useful reference for the research of rolling bearing service condition monitoring.

Abstract
Electron beam (e-beam) generated plasmas are useful for material processing applications such as deposition and etching because the plasmas deliver a large fluence of very low energy of ions to surfaces. Metastable species produced in the beam-region can also transport significant energy to the plasma periphery and surfaces. In this work, we have investigated the spatially resolved density of metastable Ar 1s5 species produced in an Ar and Ar/N2 e-beam generated plasma at pressures of 60–67 mTorr using laser-induced fluorescence (LIF). The experiments provide the first direct measure of absolute density and reduction of Ar 1s5 in an e-beam generated plasma when argon is diluted with nitrogen. These results are consistent with previous predictions of numerical modeling and measurements using optical emission spectroscopy. The present spatially resolved LIF measurements directly quantify the reduction of Ar 1s5 in the e-beam generated plasma by nitrogen admixing. This reduction was observed in the region of the electron beam and in the plasma periphery, where substrates are usually placed. For example, up to a threefold reduction of the density of Ar 1s5 was measured when the argon background was diluted with 15.5% nitrogen at pressure of 60 mTorr. Ar 1s5 reduction is attributed to excitation exchange with nitrogen molecules as well as the cooling of plasma electrons via inelastic collisions with nitrogen molecules.
High performance SAW resonator with spurious mode suppression using double-layer electrode transverse modulation
Authors: Zhang Shengkuo , Wang Hongliang , Zhang Peng , Cao Gang 
Published: October 2023

Abstract
This work aims to solve the problem of tradeoff between various properties and spurious mode suppression in surface acoustic wave (SAW) resonators. A high-angle rotated Y-cut LiNbO3 (LN)/SiO2/Si multilayered structure was proposed to balance the electromechanical coupling coefficient (K
2) and temperature coefficient of frequency (TCF), and the propagation characteristics of Rayleigh mode were simulated by the finite element method. For the widely existing spurious modes, the shear-horizontal wave and longitudinal modes were eliminated by optimizing the cut angle of LN and electrode thickness, and a method of double-layer electrode transverse modulation was proposed to suppress the transverse modes. This method reduces the mass loading effect by replacing the electrode from Cu to Cu/Al. Moreover, the Al thicknesses in different regions are changed to perform the transverse modulation, and thus a widespread suppression of transverse modes is achieved by exciting the piston mode and enhancing the energy constraint, with a significant improvement on quality factor at the resonance frequency. Eventually, the spurious-free SAW resonator has the K
2 of 9.5% and the TCF close to zero. This work provides a feasible scheme for the design of high performance SAW resonators with spurious mode suppression.
Transduction modality near instability in domain engineered relaxor ferroelectric single crystals
Authors: Finkel Peter , Lynch Chris , Amin Ahmed 
Published: October 2023

Abstract
A transduction modality based on inter-ferroelectric (FE) transitions in domain engineered single crystals, poised near an instability via mechanical clamping is reviewed. The phase transition is associated with strain levels that are much higher than what could be achieved using the linear piezoelectric mode. They are also accessible at significantly lower drive fields compared to the free state. The large FE–FE polarization change accompanying the phase switching has been utilized to demonstrate the vast electromechanical and thermal energy conversion capabilities of this sensing modality. The harvested mechanical energy density per cycle is nearly two orders of magnitude larger than that of linear piezoelectric bimorphs operating in a resonance-mode. Additionally, being a non-resonant modality, the problems associated with matching the harvester’s frequency to that of the structure (for maximum output) are obviated. Magnetoelectric energy harvesters and sensors have demonstrated similarly large coefficients. Compact broadband sound projectors fabricated using this modality have delivered 10–15 dB more source level over two and half octaves compared to the linear piezoelectric mode counterpart. Ongoing research in utilizing this modality in electro-optic modulation is discussed. Advances that have occurred over the last decade in fundamental understanding of this transduction modality and device physics are presented. It is our intent that this up-to-date review will stimulate interest in the applied physics community to further explore the benefits of this transduction modality. This review also summarizes fundamental knowledge gained of relevant issues. The focus of this review is on single crystals and thus the recent work on lead free ceramics is not addressed.
Accessing inaccessible information via quantum indistinguishability
Authors: Horvat Sebastian , Dakić Borivoje 
Published: October 2023

Abstract
In this paper we present and analyze an information-theoretic task that consists in learning a bit of information by spatially moving the ‘target’ particle that encodes it. We show that, on one hand, the task can be solved with the use of additional independently prepared quantum particles, only if these are indistinguishable from the target particle. On the other hand, the task can be solved with the use of distinguishable quantum particles, only if they are entangled with the target particle. Our task thus provides a new example in which the entanglement apparently inherent to independently prepared indistinguishable quantum particles is put into use for information processing. Importantly, a novelty of our protocol lies in that it does not require any spatial overlap between the involved particles. Besides analyzing the class of quantum-mechanical protocols that solve our task, we gesture towards possible ways of generalizing our results and of applying them in cryptography.

Published: October 2023

Abstract
PANI@FePO4@FeSi composites were prepared by one-pot synthesis. The PANI@FePO4 coating layer can effectively enhance magnetic loss, dielectric losses, and improve impedance matching by reduce the skin effect. The optimized reflection loss (RL) of the composites is −54 dB at 15.76 GHz with the absorption bandwidth (RL<−10 dB) of 2.7 GHz (14.3−17 GHz).Density functional theory (DFT) and ANSYS High-Frequency Structure Simulator (HFSS) analysis results suggest that destruction of local microstructural symmetry and inducing additional electric dipoles at the interface of each component. The density of state (DOS) of p orbital near the Fermi level decreases. Thus, dipole oscillation and polarization loss get enhanced under the external electromagnetic field. This work provides an avenue for designing new microwave absorbers.

Abstract
Herein, we prepared new nanocomposites from polyaniline (PANI) as a conductive polymer, and ferrites, MFe2O4 (M = Co2+, Cu2+, Mg2+, Ni2+, and Zn2+), as metal-oxide ceramics using sucrose sol–gel auto-combustion and in situ of polymerization. The prepared nanocomposites’ structural, thermal, magnetic, and electrical/dielectric characteristics were investigated. X-ray diffraction (XRD) revealed the formation of the metal-oxide ceramics with weak crystallinity due to their coating in the amorphous structure of the PANI matrix. Transmission electron microscopy (TEM) images exhibited the wrapping of the entire metal-oxide ceramic particles by the PANI matrix, thus confirming the core–shell structure formation. Vibrating sample magnetometer (VSM) results showed drastic reductions in all ferrites’ magnetization by their inclusion in the non-magnetic PANI matrix. The measured coercivity values showed a noticeable lowering in the presence of PANI. Besides, the thermogravimetric analysis (TG) technique indicated apparent increases in the thermal stability of the prepared nanocomposites compared to the pure PANI. Moreover, the electrical conductivity results indicated a change from metallic-like behavior for the pure PANI to the semiconductor by including the ferrites. Furthermore, by comparing the pure PANI, the dielectric properties of nanocomposites increased by the presence of ferrites, suggesting the suitability of the entire nanocomposites to be used in energy storage devices such as capacitors.
Microstructure, multi-phase and corrosion resistance of amorphous phase reinforced multi-layer fabricated by laser beam
Authors: Li Jianing , Xu Lianyong 
Published: October 2023

Abstract
The Fe-Cr-B-Si deposited layers were prepared on the titanium alloy by the laser melting deposition (LMD) or the laser cladding (LC) technology. The microstructure of the clad layer and the deposition bulk was characterized by the scanning electron microscopy, transmission electron microscopy and electron-backscattered diffraction. The single clad layer was primarily composed of the amorphous phase (APs), the fraction of APs decreased with increasing of the LMD layer thickness due to the heat accumulation, producing the crystalline phases. Parts of the nanocrystalline phases (NPs) were produced due to the characteristics of a laser-induced pool (LIP), producing the deposition bulk with the good metallurgy bond between the adjacent laser fabricated layers. The corrosion resistance of the deposition bulk was enhanced due to the production of the oxides and hydroxides, forming a passive film to enhance the corrosion resistance.
