Abstract
The NSLS-II network and computing infrastructure has been significantly updated recently. The re-IP process in 2020-2021 enabled the NSLS-II network to be routable to the rest of the BNL campus. Then, standardization of the operating systems and deployment procedures helped to deliver a consistent environment to workstations and servers used by all NSLS-II beamlines. In particular, the RedHat Enterprise Linux 8 was deployed to 700+ machines using the RedHat Satellite infrastructure management product, and all critical services (IOCs, databases, etc.) were migrated to the new OS. NFS users’ home directories are consistent across all of the machines, which eliminates the need for the individual configuration of the user environment on each host. The standard suite of software packages is available to the beamline staff and users, which includes the system packages (deployed via RPM) as well as the conda environments for data acquisition and analysis. Security measures were implemented to comply with the industry standards, which include multi-factor authentication (using Duo), secure screen lock for the beamline machines, and advanced access control to the experimental data that is stored in shared central storage available on all hosts. These major enhancements facilitated sharing the experimental data (currently for a number of selected beamlines, with a plan to extend it to the whole facility in the nearest future) with the users via an externally facing JupyterHub instance - https://jupyter.nsls2.bnl.gov. The beamlines keep using the Bluesky data acquisition framework to orchestrate their experiments, and the new infrastructure enabled them to use a next-generation data access library called tiled.

Abstract
TARUMÃ is a multi-technique station at CARNAÚBA (Coherent X-Ray Nanoprobe Beamline) at the 4th-generation light source Sirius at the Brazilian Synchrotron Light Laboratory (LNLS). With a tender-to-hard energy range from 2.05 to 15 keV and a fully coherent nanoprobe focused via an all-achromatic KB (Kirkpatrick-Baez) optics, it can be used for simultaneous multiple nanoscale X-ray techniques in 2D and 3D. This includes ptychography coherent diffraction imaging (ptycho-CDI), absorption spectroscopy (XAS), diffraction (XRD), fluorescence (XRF) and luminescence (XEOL). In particular, the tender energies can be used to study light elements that are commonly present in soft biological samples, ensuring the unique position of the station in the Life and Environmental Sciences program at LNLS. Still, enabling this range of experiments is sometimes only possible with cryogenically cooled samples as the high beam dose can result in both chemical and structural damage at ambient temperature conditions. At TARUMÃ, to comply with the heavily occupied volume around the sample and the sample positioning architecture, this is enabled by an open-atmosphere cryogenic system based on a commercial cryojet and a custom-designed sample holder. Following a predictive engineering approach, the system is capable of conditioning the sample down to 155K, whilst avoiding icing and condensation in nearby instrumentation and preserving the nanometer-level positioning requirements of the scanning station. Here we present the commissioning results of the referred system along with the first beamline measurements.

Abstract
For the study of thin films and fibres under load, a uniaxial tensile stage has been developed for synchrotron-based polarized Fourier-transform infrared (FTIR) microspectroscopy. One of the advantages compared to commercial available stages is its compact design at the sample position (<20 mm thickness) and the large field of view on the sample for transmission and reflection geometry. In addition, the stage is mounted on a base plate, which can be rotated between -15° and +193° in the sample plane, in order to rotate the sample relative to the inherent polarization of the incoming infrared light from the synchrotron light source. Preliminary in situ tensile load experiments conducted at MIRAS beamline of the ALBA synchrotron were done on 3D printed thermoplastic polyurethane (TPU) polymer thin films. The samples could be mapped in transmission geometry under tensile load achieving high spatial resolution up to 10 micros using the intense IR source of the synchrotron light. Making use of polarized synchrotron-based infrared light, it was possible to show the alignment of different vibrational bands parallel and orthogonal to the stretching direction. The v(C=O) absorbance bands decrease upon stretching using parallel polarized infrared light, while the v(C=C) bands are increasing in intensity, revealing the orientation of v(C=O) bonds orthogonal to the stretching direction during stretching. The experiments highlight the unique instrumentation capabilities of the tensile stage for in situ measurement of molecular distributions and chemical bond orientations as a function of sample displacement and applied load.

Abstract
Synchrotron Endstations typically use a stack of coarse and fine motion stages to position and scan a sample in the beam. The serial nature of this design causes a low resonant frequency and hence limits the position stability. The combination of multiple stages also adds motion control and data analysis complexity. A large range parallel kinematic cartesian sample scanner has been designed, built, tested and installed to address these limitations. The stage combines a 3 mm travel range with < 3 nm RMS position jitter in the scan directions and < 1 nm/minute thermal drift during scanning. This paper describes and demonstrates the mechatronic design process of Dynamic Error Budgeting. The stage is installed and fully operational on beamline I14 at the Diamond Light Source being used for nanoscale XRF mapping, imaging and ptychography.

Abstract
Double multilayer monochromators (DMMs) for 40 keV and 110 keV have been installed at BL20B2 in SPring-8. The DMMs provide X-rays with a few percent bandwidths at those energies. The flux density of the X-rays is more than several hundred times higher than that of monochromatic X-rays with a silicon double crystal monochromator, which enables us to perform high-speed X-ray imaging with a large field of view and high spatial resolution X-ray imaging in those high-energy X-rays. Here characteristics of DMMs and some demonstrations of X-ray imaging using the high flux density beams are shown.

Published: December 2022

Abstract
This paper presents an image reconstruction method for reflective ultrasonic tomography. The variation of the time corresponding to the first peak for the transmitter-receiver pairs is used in the transmission tomography. Commonly, all the reflected packets are used in the reflective reconstruction, but here we assume that the inside of the object is either changing or has a high absorption coefficient. Classical tomography methods are based on an equation where the system matrix is not square. Therefore, inverting such a matrix is a complex task. The solution to this problem is our simple geometrical method, which is very fast and accurate. Moreover, a very high spatial resolution can be achieved. In this case, the amount of information obtained from the system is limited only by the number of transducers used for the ultrasonic measurement.

Abstract
Separation of seed mixtures for the purpose of their purification or calibration by fractions is a mandatory technological operation in the processing of most crops. Due to its properties, the process of separation of seed mixtures of individual crops has undefined parameters or low efficiency of its flow. A similar seed material is safflower, the parameters of the purification process of which were determined in the work taking into account different methods of separation of the components of the mixture. The work involves determining the parameters of the holes of the sieves and the scheme of their installation during the separation of the seed mixture of safflower, provided the maximum quality of seeds. For this purpose, the dimensional characteristics of safflower seeds and characteristic impurities were determined, which allowed to determine the possibilities of their qualitative separation. As a result of experiments, variation curves of dimensional characteristics of safflower seed mixture components in thickness and width were established. To imitate hard-to-separate components, winter wheat and pea grains were added to safflower seeds. The efficiency of sieve separation was also determined taking into account different types of sieve openings. Studies of the process of purification of safflower seed mixture were performed both on traditional flat stamped sieves and on the proposed sieves with activators. A study on the separation of safflower seed mixtures on traditional sieves with round holes with a diameter of 5.0 mm and rectangular holes with a width of 3.0 mm has been carried out. For the first time, a sieve with five-petalled epicycloid and volume activators was used to clean the seed mixture, which, thanks to the innovative design, allows us to increase the efficiency of the separation process. For the first time, a well-grounded method of determining the coefficient, which comprehensively takes into account the parameters of holes and jumpers, can be used to optimize the parameters of seed and grain cleaning machines. The separation efficiency of the safflower seed mixture was determined both by the content of fractions and by the indicators of 1000 seed weight, germination energy and seed germination. It has been found that to increase the productivity and quality of separation, it is advisable to use sieves with sieve activators: the upper sieve with five-petalled epicycloid activators 5 mm, and the lower with elongated holes 3 mm wide as well as volume activators.

Published: December 2022

Abstract
In this work we present the development of a monitoring system that is targeted to track the data of electrical potential measurements in biological tissues. The system is conceived to be portable and its design allows for low-energy consumption. To account for different types of biological materials, the measurement of the bioimpedance of the material is generally used. To achieve both speed and accuracy, we deploy a system using hardware-software codesign with reconfigurable hardware. This integral approach is facilitated by the use of a modern system of chip with mixed signal capabilities. In particular we use a field programmable gate array for accelerating signal processing and data acquisition. A double core microcontroller is used to collect, process and deliver the data over a networked environment.

Published: December 2022

Abstract
The article presents the change in temperature to time ratio of the solenoid winding depending on the working fluid flow. This measurement is extremely important from the point of view of the stimulation of biological material using the electromagnetic field, due to the possibility of denaturing the protein of the organic substance, which transfer into false experimental results. The differences in temperature to time ratio between the coil winding and the working fluid were presented and the results were supplemented with pictures from a thermal imaging camera. An attempt was also made to determine the theoretical reserve of the thermal energy flux. The obtained results will be used to create a system that will fully automatically control the set temperature of the cooling liquid, with the possibility of its cyclical changes.

Published: December 2022

AbstractIn this work, dip coating process (DCP) was used to synthesize TiO2 nanoparticles (NPs). The photocatalytic nanostructured heterojunction was formed on ZnO nanoseeds (NSs) layer grown by radio frequency (RF) sputtering on flexible Teflon (PTFE) substrate. Series of characterizations and analyses reveal the morphology, optical, and structural properties of the nanocomplexes. These include several identified peaks observed by XRD. While, UV-Vis reflectance spectroscopy, photoluminescence (PL), and FTIR were utilized to determine the opto-characteristics, and to observe the presence of functional bonds involved in the growth of the heterojunction thin film. Based on the presented results, the heterostructures relying on a flexible substrate are believed to be highly promising for photocatalytic applications.

Abstract
Surface plasmon resonance (SPR) sensors have many applications in detecting toxic gases, water pollutants, and biomarkers of many diseases. Surface plasmon resonance sensors are a good candidate for future sensing platforms due to their high sensitivity and fine resolution. However, the challenges of high cost, cross-sensitivity, and large amount of generated data need to be addressed to unlock surface plasmon resonance potential. Machine learning (ML) algorithms can address these challenges. In this short review, recent studies integrating the algorithms of Artificial Intelligence (AI) and Machine Learning (ML) with (SPR) sensing mechanisms for bio-detection applications are presented here. This short review shows how the integrated approach can help mitigate some of the challenges faced by traditional SPR sensing.

Authors: Zaiton A M , Joyce Y P L , Ahmad Z , Jasman F , Hassan W H W 
Published: December 2022

Abstract
Light Fidelity (Li-Fi) is a wireless technology that utilizes light emitting diodes to convey data. Li-Fi has emerged as a promising alternative to radio frequency communication technology in recent years. This paper examines the performance characterisation between NRZ-OOK and carrier-less amplitude-phase modulation (CAP-2, CAP-4 and CAP-8), within a simulated Li-Fi environment. For the parameters of interest, the eye pattern, bit error rate (BER) and constellation diagram are reported. As no distance is specified in the simulation, the BER for CAP is zero, allowing an ideal transmission to be emulated. The scatter diagram increases as the number of CAP modulations increases. For the eye pattern, CAP modulation provides a better visual representation of how noise might affect system performance compared to OOK modulation.

Published: December 2022

Abstract
Self-image interference in a single mode-no-core-single mode fiber plays an important role especially for length optimization before acting as a sensor. The interference can be observed through optical simulation software. Past literature has successfully demonstrated the interference via COMSOL Multiphysics®, but the simulation was not restricted to the use of important domains and settings such as perfectly matched layer and surrounding domain causing imprecise simulation results. This paper proposes a simulation of self-image interference in a single mode-no-core-single mode fiber by using the wave-optics module in COMSOL Multiphysics® software. The beam propagation method is used to observe the self-image interference for different self-image indexes ranging from one to four indexes while the self-image length is obtained from the theoretical calculation before a simulation is carried out. The results show that accurate results can be obtained with restricted simulation settings. The number of the self-image index and self-image length produced by the simulation are similar to the calculation. The self-image point is located exactly at the calculated length with a four-decimal point 0.0000 difference, thus overcoming the limitation of the simulated previous work. In the future, the simulation settings and results can be used for reference to simulate the single mode- no-core-single mode fiber structure.

Abstract
New type plasmonic sensitizer, titanium nanoparticles (Ti NPs) shown potential in enhancing photoluminescence of rare-earth ions (REIs) as doped into magnesium zinc-sulfophosphate (MZS) glass for optical to optic application. Here, neodymium ions (Nd3+)-doped MZS glass with Ti NPs inclusion gone heat treatment (HT) at 450°C for 6 and 12 hours in order to tune the NPs size and tailor their plasmonic strength. The sample was characterized using X-ray diffractometer (XRD), high-resolution transmission electron microscope (HRTEM), and photoluminescence (PL) spectrometer. Heat treatment (HT) grows Ti NPs with a mean size ≈ 16 nm. The SPR bands are probed around 585and 739 nm. The SPR band intensities change with HT duration. The NIR PL bands were perceived around 878 nm, 1050 nm and 1322 nm corresponding to 4F3/2→4I9/2, 4F3/2→4I11/2 and 4F3/2→4I13/2 transitions, accordingly. The PL transition 4F3/2→4I9/2 (878 nm) and 4F3/2→4I13/2 (1322 nm) is enhanced about 1.44 and 1.52 times respectively, after 12 hours HT. The results show that HT enhances PL through SPR amplification. These findings may be useful in developing solid-state lasers and optical materials.

Abstract
The problem encountered in the culture of asian redtail catfish is its slow growth. The increase in growth can be accelerated by the addition of bromealin enzymes found in pineapple processing industrial waste. The aim of this research was to analyze: the optimal dose of bromealin enzyme added to feed in increasing the activity of digestive enzymes and growth performance of asian redtail catchfish. The main ingredients used were asian redtail catchfish (Hemibagrus nemurus) measuring 5-7 cm, pakcoy plants, boster, bromealin enzymes, commercial pellets with 38% protein content, round tubs and gutters as test containers. The method of research used is Completely Randomized Design (CRD) experimental method with 1 factor, 5 levels of treatment and 3 replications. The treatment levels in this study were: without bromealin enzyme (P0), 2.5% kg-1 feed (P1), 3.5% kg-1 feed (P2), 4.5% kg-1 feed (P3) and 5.5% kg-1 feed (P4) respectively. To determine the effect of treatment, variance analysis (ANOVA) was performed using SPSS software version 13.0. The results showed that bromelin enzymes with different doses had an effect on digestive enzyme activity and growth performance of asian redtail catfish. The best treatment was found in the treatment of bromealin enzyme at 5.5 g kg-1 feed, which increased the protease enzyme by 95.56%, lipase 612.12%, amylase 338.12%, average growth weight of 13.85 grams, average growth length of 12.03 cm, absolute growth weight of 33.47 grams, absolute growth length 6.17 cm, specific growth rate of 2.92 %, Feed Efficiency of 69.33%, FCR of 1.45% and survival rates of 92.86% with water quality parameters such as temperature 24.33-29.73 °C, pH 6.17-7.67, dissolved oxygen (DO) 3.53-7.57 mg L-1, and ammonia 0.00537 mg L-1.
