Published: November 2023

Abstract
Time independent Schrodinger wave equation (SWE) for a quantum system can be solved computationally which involves application of numerical method. Different computational tools used to solve SWE involving different potentials were reviewed. XCOS, an inbuilt tool of Scilab for modelling and simulating hybrid dynamic system and is an open-source is used to solve the Schrodinger wave equation for different quantum systems. Only basic understanding of mathematics up to high school level is required to solve Schrodinger wave equation using XCOS. Different quantum systems considered are free particle in a well bounded by infinite potential at the boundaries, radial part of SWE for Hydrogen atom under coulombic potential, screened coulombic potential. Radial part of Schrodinger wave equation for a particle under harmonic and anharmonic potential were also solved using XCOS computational tool. Eigenvalues and eigenvectors were obtained by solving radial part of Schrodinger wave equation for molecules under Morse potential. Advantages and limitation of XCOS computational tools were also discussed. We argue in favour of the academic use of computational tool XCOS to solve Schrodinger wave equation in introductory quantum mechanics courses.

Published: November 2023

Abstract
We investigate the impacts of backward scattering (BS) of non-Kolmogorov turbulence on the entangled perfect Laguerre–Gaussian (PLG) beams. The explicit expressions for PLG quantum entanglement and quantum coherence are derived in the BS case. We find that the introduction of BS reduces the entanglement and coherence, disrupts the initial decay characteristics, and induces the revival of entanglement and coherence, in which sense turbulence may possess a non-Markovian (memory) effect. As the OAM number increases, the non-Markovian feature increases logarithmically. In addition, the universal decay of entanglement and coherence and the non-Kolmogorov effects are also explored.

Published: November 2023

Abstract
Laser speckle is a non-contact, non-interfering, non-destructive, rapid and controllable technique with a large area of coverage that has attracted much attention for surface analysis of materials. The emergence of different natural cellulosic materials as potential candidates for the replacement of synthetic ones is promising, but their sustainability from the point of view of material design is still in question. Machining of the surface of cellulosic components for making sound-dampening materials has a critical effect on determining their surface condition. Laser speckle is an emerging tool for surface analysis of a variety of materials, and it has important applications in material design and analysis. As a cutting-edge research tool, ultrasonic wave technology has maintained a significant contribution to the design and structural monitoring of composite materials. The present work uses date palm leaf fibers for composite reinforcement. The sound-dampening properties, such as sound absorption and transmission, were analyzed on the basis of surface roughness observed with the laser speckle technique and modified by ultrasonically blended surfactants. The surface roughness of the synthesized material was found to increase with sonication time with an R
2 value of 0.944 and observed fluctuation in roughness data on the surface of the material. The sound absorption coefficient is 0.98 with a transmission loss of 60 dB, for which the material is classified as an ASTM E1050 Class A acoustic material. Further, the method of laser speckle-based roughness estimation is found to be potential tool for the design of any type of quieter material.
Simulation of x-ray bremsstrahlung generation under vacuum heating of solid target electrons
Authors: Kostenko O F 
Published: November 2023

Abstract
An extended Brunel model of hot electron generation in nonrelativistic laser-plasma interactions is considered. The model takes into account the permittivity of the surface plasma and the energy absorbed by electrons accelerated by the electric field components perpendicular and parallel to the target. A model for the generation of x-ray bremsstrahlung in the case of a Gaussian laser beam is presented. It is shown that the influence of electron motion parallel to the plasma surface on the absorbed intensity becomes distinguishable only at relatively low absolute values of the permittivity. Calculations of the dependences of the yield of hard bremsstrahlung x-rays on the angle of incidence of laser radiation and on the energy interval in which the yield of bremsstrahlung is measured are in qualitative agreement with the experimental data, if we assume that the electron concentration in the skin layer is relatively low (approximately 5–7 times the critical concentration).
Neutron radiation induced effects in 4H-SiC PiN diodes
Authors: Gsponer Andreas , Gaggl Philipp , Burin Jürgen , Thalmeier Richard , Waid Simon , Bergauer Thomas 
Published: November 2023

Abstract
Silicon carbide (SiC) is a wide band gap semiconductor and an attractive candidate for
applications in harsh environments such as space, fusion, or future high luminosity colliders. Due
to the large band gap, the leakage currents in SiC devices are extremely small, even after
irradiation to very high fluences, enabling operation without cooling and at high
temperatures. This study investigates the effect of neutron irradiation on 50 μm p-n 4H-SiC
diodes using current-voltage, capacitance-voltage, and charge collection efficiency (CCE)
measurements up to neutron fluences of 1 × 1016
n
eq/cm2. The leakage
currents of the investigated devices remained extremely small, below 10 pA at 1.1 kV reverse bias.
In the forward bias, a remarkable drop of the current was observed, which was attributed to an
increased epi resistivity due to compensation of the epi layer doping by deep-level defects. The
CCE was evaluated for alpha particles from a radioactive source, a 62.4 MeV proton beam at the
MedAustron ion therapy center and using UV-TCT. The charge collection efficiency in reverse bias
was shown to scale directly with the 1 MeV equivalent fluence Φeq as CCE∝Φeq
-0.63±0.01. A CCE better than 50% was able to be obtained for
fluences up to 1 × 1015
n
eq/cm2. Because of the low currents in the
forward direction, particle detection was also possible in forward bias, where the CCE was found
to be increased relative to reverse bias. Furthermore, a significant dependency on the amount of
injected charge was observed, with the CCE surpassing 100% in alpha and UV-TCT measurements,
requiring further systematic investigation.
Active correction of window Faraday effects for ITER laser diagnostics

Published: November 2023

Abstract
Measurement of the change in polarization of a laser beam traversing a magnetized plasma is a standard diagnostic technique for extracting key plasma parameters, including density and current profile. Depending on the polarization orientation of the incident laser beam relative to the

plasma
magnetic field, the polarization change is denoted as either Faraday rotation or Cotton-Mouton effect. On ITER three laser diagnostics will make use of this effect to make their measurements. Unfortunately, this effect is also evident when the laser beam passes through the vacuum window. The large magnetic field and finite verdet constant of the window material mean that on ITER this effect — in particular faraday rotation — is non-negligible, and needs to be disentangled from the desired measurement parameter. The Toroidal Interferometer-Polarimeter (TIP) and Density Interferometer-Polarimeter (DIP), in particular, are affected. Both diagnostics use lasers in the 5–10 μm range, and will use zinc-selenide (ZnSe) as the vacuum window material.

In order to compensate for the unwanted window distortion a sensor is being developed to monitor the magnetic field perpendicular to the window and actively

correct
for the faraday rotation in real time. The sensor consists of an inductive coil closely fitted just in front of the window disc. It comprises several turns of fine wire in center-tap configuration. Both the raw voltage signal, as well as the integrated signal, will be monitored to estimate the magnetic field through the window disk. The system is designed to measure fields up to B <1 T with an accuracy of 0.01 T, at frequencies of D.C. to 1 kHz. The backend electronics will leverage off similar technology developed for other ITER magnetics systems. Using the real-time magnetic field information, in conjunction with published and/or measured data on the verdet constant of the ZnSe window material, in-house developed software will estimate the faraday rotation induced by passing through the window.

An initial prototype of the sensor has been fabricated and results from preliminary characterization trials of the system are presented. Detailed testing is planned for the future using the DIP system prototype currently under development.
Measurement of the detection efficiency of a 100 µm thin plastic scintillator for muons with p = 28 MeV/c
Authors: Stäger David ,   the muEDM collaboration
Published: November 2023

Abstract
In the muEDM experiment, a gate detector is used to trigger the storage mechanism when a muon enters the experimental apparatus. This detector should operate at full efficiency and low thermal noise contamination. Furthermore, it should have a very low material budget to minimize the deflection of the muon trajectory by multiple coulomb scattering. A first prototype of this detector is a 100 µm thick plastic scintillator, connected to eight silicon photomultipliers reading out the scintillation light. In a dedicated beamtime at the πE1 beamline at the Paul Scherrer Institute, we measured the detection efficiency of this scintillator with 28 MeV/c muons.

Published: November 2023

Abstract
The Super Tau Charm Facility (STCF) is a high-luminosity
electron-positron collider experiment operating at center-of-mass
energy of 2–7 GeV. Its primary goal is to explore flavor
physics, CP-violations, and investigate physics beyond the Standard
Model. The inner tracker (ITK) is a crucial component of the STCF
tracking system, which is responsible for detecting particle hits,
especially those with low momentum below 100 MeV/c. Its primary
objectives include providing high detection efficiency and spatial
resolution for charged particle tracks. However, the electronics of
ITK is susceptible to single-event upset (SEU) caused by
beam-related background. To address this, this paper presents a
prototype of FPGA (Field Programmable Gate Array)-based electronics
that can detect and automatically repair SEU induced soft errors in
its Configuration Random Access Memory (CRAM) and whose Block Random
Access Memory (BRAM) has been also subjected to commonly used
hardening techniques. Importantly, the prototype's corrective
operations do not result in any dead time due to hot redundancy
backup. In the laboratory environment, we measured the bit error
rate of the data transmission to be lower than 10-12 with a
confidence level of 99.99%. Through neutron beam experiments
conducted at China Spallation Neutron Source (CSNS) back-n white
neutron source. We demonstrated that the readout electronics can
effectively restore correct functionality and promptly rectify soft
errors.

Published: November 2023

Abstract
Eight EXOGAM-type, Ge-clover detectors of the EXILL array,
arranged on an octagon plan and acting as Compton polarimeters, were
used to measure directional-polarization correlations of γ
rays populated in various processes. Measurements of γ
radiation following neutron-induced fission of 235U and
241Pu targets; β
--decay following fission; (n,γ)
reactions on various stable targets and measurements using
radioactive sources of 60Co, 133Ba and 152Eu were
performed at the PF1B cold-neutron facility of the Institut
Laue-Langevin in Grenoble. Digital electronics and a trigger-less
acquisition system allowed the collection of signals from Ge
detectors down to about 20 keV, providing measurements of linear
polarization down to 120 keV. The precise sensitivity
calibration was determined for the set of eight EXILL clover
polarimeters in a range from 100 keV to 10000 keV. A new formula
for calculating the directional-polarization correlations for the
upper transition in a γγ cascade is derived from first
principles. Directional-polarization correlations were measured for
a few dozens of transitions in a number of nuclei, including values
for twenty transitions in the 152Sm nucleus measured for the
first time, and compared against the calculated values, to
illustrate the quality of the technique. The combined analysis of
angular and directional-polarization correlations is presented,
which helps the determination of spin-parity assignments to excited
levels.

Published: November 2023

Abstract
Intercellular communication is critical to the understanding of human health and disease progression. However, compared to traditional methods with inefficient analysis, microfluidic co-culture technologies developed for cell–cell communication research can reliably analyze crucial biological processes, such as cell signaling, and monitor dynamic intercellular interactions under reproducible physiological cell co-culture conditions. Moreover, microfluidic-based technologies can achieve precise spatial control of two cell types at the single-cell level with high throughput. Herein, this review focuses on recent advances in microfluidic-based 2D and 3D devices developed to confine two or more heterogeneous cells in the study of intercellular communication and decipher the advantages and limitations of these models in specific cellular research scenarios. This review will stimulate the development of more functionalized microfluidic platforms for biomedical research, inspiring broader interests across various disciplines to better comprehend cell–cell communication and other fields, such as tumor heterogeneity and drug screening.

Published: November 2023

Abstract
Nowadays, remarkable progress has been observed in research into neuromorphic computing systems inspired by the human brain. A memristive device can behaviorally imitate the biological neuronal synapse therefore memristor-based neuromorphic computing systems have been proposed in recent studies. In this study, the memristive behaviors of titanium dioxide sandwiched between two platinum electrodes were investigated. For this purpose, three SiO2/Pt/TiOx/Pt thin films with 7.2 nm, 40 nm, and 80 nm TiOx metal-oxide layers were fabricated using a pulsed laser deposition technique. The fabrication process, structural properties, photoluminescence properties and electrical transport characterization of each thin film have been investigated. All thin films were analyzed in terms of the film stoichiometry and degree of oxidation using high-resolution x-ray photoelectron spectroscopy. By measuring the layer thickness, density, and surface roughness with the x-ray reflectivity technique, by analyzing the structural defects with photoluminescence spectroscopy and by characterizing the quasi-static electrical properties with the conventional two probes technique, we have shown that the fabricated memristive devices have bipolar digital switching properties with high ROFF/RON ratio. This type of switching behavior is applicable in random access memories. Experimental current–voltage behavior in the form of pinched hysteresis loop of the films have been modelled with generalized memristor model.

Published: November 2023

Abstract
Multi-walled carbon nanotubes (MCNTs)-enhanced glass fiber composite (GFC) laminates are among the most promising materials for fulfilling various structural and non-structural requirements. They have also shown exceptional functional applications as excellent electrical and thermal conductors, as well as electromagnetic interference shielding materials. The present work primarily focuses on developing regression models for the drilling process of 0.3 wt% MCNTs-GFC laminates. For experimentation, three different coated drills—carbide, TiCN-coated, and TiAlN-coated—are used under both dry and chilled air cutting environments. The lowest thrust force, torque, and delamination factor were observed at a feed rate of 10 mm min−1 and a speed of 1500 RPM using a TiCN-coated drill in a chilled air environment. Regression analysis reveals that feed rate significantly influences thrust force, as justified by the R2 value, which is above 90% for the selected cutting conditions. The corresponding t and F statistics values indicate the statistical significance of the relevant explanatory factors. The efficiency of the developed models is further validated by considering the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) values, which are 136.9 and 144.7, respectively. These values indicate a good regression fit and likelihood of the models for data prediction. Additionally, there is a strong correlation (coefficient > 0.85) between thrust force and delamination factor under the selected cutting environments. Concurrently, the developed regression models are simulated and evaluated for random experiments (Nos. 87, 125, 187, 243, 244, and 399), and the predicted responses closely match the experimental values.
Experimental investigation on trinary blended geopolymer mortar synthesized from Industrial-agro and municipal solid waste ash subjected to different acid exposure
Authors: Tipraj Babu , Shanmugapriya T 
Published: November 2023

Abstract
Geopolymer binders prove to be a reliable option to avoid dependency on conventional binders, and reduce the burden on the environment. The current study assesses the durability characteristics of a developed mortar made from a combination of Granulated blast furnace slag (GBFS), Sugar cane bagasse ash (SCBA), and Municipal solid waste ash (MSWA). The Geopolymer mortar specimens were cured under ambient conditions after the ternary blended mix had been activated by a solution of sodium silicate and sodium hydroxide of 8 M (SS/SH-2.5). Mass loss and compressive strength were measured at various time regimes of acid attack studies under mild concentrations of 3% sulphuric acid, hydrochloric acid, and nitric acid. The durability, macroscopic, microscopic, and morphological, studies were carried out. The results indicated that trinary blended geopolymer mortar exposed to sulphuric acid showed less mass loss and high compressive strength retention compared to the control mortar. The nitric acid exposure exhibited comparable strength loss for the trinary blend with control mortar and hydrochloric acid showed negligible effect on mortar. Mass loss was more significant in sulfuric acid than the hydrochloric and nitric acid. RCPT and Carbonation tests revealed that geopolymer mortar exhibits moderate chlorine ion penetration and the ingress of CO2 was less in the trinary blend mix. The mineralogical studies showed the formation of gypsum, nitrate, and chloride products. The optical microscopic image revealed the ingress of sulfuric acid is more intense in the mortar compared to hydrochloric and nitric acid and microstructural studies witnessed the degradation of C-A-S-H supported by EDX.
A kinetic study on oxygen redox reaction of a double-perovskite reversible oxygen electrode— Part II: Modelling analysis
Authors: Bianchi Fiammetta Rita , Asensio Antonio Maria , Clematis Davide , Bosio Barbara , Barbucci Antonio 
Published: November 2023

Abstract
Mixed ionic and electronic conductor double perovskites are very promising oxygen electrode materials for solid oxide cell technology. However, understanding their specific kinetic mechanism is a fundamental preliminary step towards detecting the best reachable performance, optimising the operation conditions and the electrode architecture. Indeed, the contributions of different rate-determining steps can vary as a function of the working point. In this framework, after a detailed experimental campaign devoted to the study of SmBa0.8Ca0.2Co2O5+δ
(SBCCO) oxygen electrode behaviour, the authors propose a theoretical analysis of oxygen reduction and oxygen evolution reaction paths that couples a preliminary study through equivalent circuit analysis with a physics-based model to predict the operation of SBCCO as a reversible oxygen electrode. Following a semi-empirical approach, the kinetics formulation was derived from thermodynamics and electrochemistry fundamental principles and was tuned on electrochemical impedance spectroscopy (EIS) spectra in order to retrieve the unknown kinetic parameters. The successful cross-checking of the simulated results with the experimental data obtained by direct current measurements validated the proposed model, here applicable in further works on full cells to simulate the SBCCO oxygen reversible electrode performance.
Toward equitable grid resilience: operationalizing climate adaptation strategies to mitigate flooding impacts

Published: November 2023

Abstract
Disadvantaged communities are disproportionately affected by flooding, exacerbated by climate change. This paper presents a novel framework for incorporating environmental justice into climate adaptation planning of power grids against flooding. A new energy equity metric is introduced with the vision that addressing environmental justice warrants prioritizing disadvantaged communities that have lower risk thresholds. The framework is applied to a levee-protected IEEE standard test system in northern California. The grid performance disturbed due to flooded substations is investigated under current and future climate. The mathematical model of the framework is structured as a two-stage stochastic mixed-integer programming model. This model aims to minimize the equity gap in grid resilience (EGGR) between disadvantaged and non-disadvantaged communities while enhancing the system resilience by reducing the risk of power outages due to flooding. The results show that climate change undermines grid resilience, with disproportionally worse impacts on disadvantaged communities. A significant EGGR is observed that worsens under a changing climate. For adaptation, the optimal placement of distributed energy resources is determined by maximizing the grid resilience to flooding while minimizing EGGR. The proposed framework can equip decision-makers with a robust tool for operationalizing equitable climate adaptation strategies for power grids.
