Abstract
As an additive manufacturing process, material jetting techniques allow to selectively deposit droplets of materials in liquid or powder form through a small-diameter aperture, such as a nozzle of a print head. For the fabrication of printed electronics, a variety of inks and dispersions of functional materials can be deposited by drop-on-demand printing on rigid and flexible substrates. In this work, zero-dimensional multi-layer shell-structured fullerene material, also known as carbon nano-onion (CNO) or onion-like carbon, is printed on polyethylene terephthalate substrates using drop-on-demand inkjet printing. CNOs are produced using a low-cost flame synthesis technique and characterized by electron microscopy, Raman, x-ray photoelectron spectroscopy, and specific surface area and pore size measurements. The produced CNO material has an average diameter of ∼33 nm, pore diameter in the range ∼2–40 nm and a specific surface area of 160 m2.g−1. The CNO dispersions in ethanol have a reduced viscosity (∼1.2 mPa.s) and are compatible with commercial piezoelectric inkjet heads. The jetting parameters are optimized to avoid satellite drops and to obtain a reduced drop volume (52 pL), resulting in optimal resolution (220 μm) and line continuity. A multi-step process is implemented without inter-layer curing and a fine control over the CNO layer thickness is achieved (∼180 nm thick layer after 10 printing passes). The printed CNO structures show an electrical resistivity of ∼600 Ω.m, a high negative temperature coefficient of resistance (−4.35 × 10−2 °C−1) and a marked dependency on relative humidity (−1.29 × 10−2 RH%
−1). The high sensitivity to temperature and humidity, combined to the large specific area of the CNOs, make this material and the corresponding ink a viable prospect for inkjet-printed technologies, such as environmental and gas sensors.

To that end, we start by reviewing the historical context and essential theoretical developments, before focusing on the decades of progress made in high-energy collider experiments. Special attention is given to the evolution in experimental approaches in response to various challenges, to the demanding detector capabilities required to unambiguously identify the linear Breit–Wheeler process, and to the connections with VB. We close the report with a discussion, followed by a look at near-future opportunities for utilizing these discoveries and for testing quantum electrodynamics in previously unexplored regimes.

Published: June 2023

Abstract
Lateral depletion-mode, beta-phase gallium oxide (β-Ga2O3) metal-oxide-semiconductor field-effect transistors (MOSFETs) with source-drain spacings of 3 µm, 8 µm, and 13 µm are studied using a modified transfer length method (TLM) to obtain sheet resistances in the gated and ungated regions as well as to observe their gate electric field dependence. The modified TLM requires the contact resistance to be independent of the gate-source voltage, or changing current density. We verify this by performing measurements on conventional TLM structures in dark and UV conditions and observe a changing current density with constant contact resistance, enabling the development of the proposed method. The conventional and modified TLM give sheet resistances of 20.0 kΩ sq−1 ± 1.0 kΩ sq−1 and 27.5 kΩ sq−1 ± 0.8 kΩ sq−1, respectively. Using a traditional method for determining the channel resistance, the modified TLM improves the convergence of the channel resistances between the three devices, showing higher accuracy than the conventional TLM structures. Gate-source voltage dependence of the sheet resistances is seen in the ungated regions, leading to non-ideal behavior which cannot be observed using the traditional method and conventional TLM structures. These results and analysis methods are important in improving MOSFET parameter extraction and understanding the gate electric field effects on the channel and series resistances in β-Ga2O3 MOSFETs.
Dexamethasone release pattern via a three-dimensional system for effective bone regeneration
Authors: Channey Hareet Singh , Holkar Ketki , Kale Vaijayanti , Ingavle Ganesh 
Published: June 2023

Abstract
For over a decade, dexamethasone (DEX) has been used for bone regenerative and anti-inflammatory purposes. It has also shown promise for inducing bone regeneration by using it as component of osteoinductive differentiation medium, particularly for in vitro culture models. Despite its osteoinductive properties, its use is limited due to its associated cytotoxicity, particularly when used at higher concentrations. DEX has adverse effects when taken orally; thus, it is best to use it in a targeted manner. Even when given locally, the pharmaceutical should be distributed in a controlled manner based on the needs of the wounded tissue. However, because drug activity is assessed in two-dimensional (2D) circumstances and the target tissue is a three-dimensional (3D) structure, assessing DEX activity and dosage in a 3D milieu is critical for bone tissue development. The current review examines the advantages of a 3D approach over traditional 2D culture methods and delivery devices for controlled DEX delivery, particularly for bone repair. Further, this review explores the latest advancement and challenges in biomaterial-based therapeutic delivery approaches for bone regeneration. This review also discusses possible future biomaterial-based strategies to study efficient DEX delivery.
Grain size trend analysis for sediment characteristic of Cirebon Waters
Authors: Agusta V C , Putri M R 
Published: June 2023

Abstract
This research aims to understand the sediment characteristic of Cirebon waters using a grain size trend analysis (GSTA). The GSTA can be used to determine sediment physical characteristics and demonstrate the sedimentary processes. A total of 32 seabed surface sediments were analyzed by measuring the size of sedimentary grains using the Mastersizer 2000 instrument and calculating grain size parameters such as mean grain size, sorting, skewness, and kurtosis using geometric methods in the Gradistat program. Analysis of grain size showed that sediments in the Cirebon Waters are dominated by silt with ranges from 7.765 to 33.43 µm (very coarse to fine silt). The mean grain size and skewness values indicated an increase in current energy and sediment transport rate from the southwest to the northeast part of Cirebon Waters. Sediments are poorly sorted, and kurtosis is predominantly mesokurtic type. All sediments were deposited by deposition mechanism in pelagic suspension and affected by slow deposition from quiet waters. Granulometric analyses become a good proxy to give fundamental information on sediment dynamics.

Abstract
Semarang coastal zone is one of the essential area in Indonesia. The area included ports and other land access that passes through the Semarang coast, the city’s central point of rapid development. The characteristic of the soil is one of the crucial parameters for base supporting regional planning, which is growing fast by the time. Currently, the capacity of the soil according to SNI 1706-2019 can refer through Vs30 data. As we know, Vs30 data provides an overview of the seismicity in an area. The main issue is that the empirical data of Vs30 is relatively expensive to acquire. Thus, many practitioners use a method by correlating data from CPT-u or SPT-N. The study approached the Vs30 data derived from the CPT-u then compared with the Vs30 data from SPT-N. The result shows that the value of Vs30 derived by CPT-u and N-SPT have a similar range of value to determining seismicity hazard particularly within the coastal area.

Published: June 2023

Abstract
Bumiaji Sub-District is located in a mountainous area with a high-risk level of landslides. Throughout 2017-2022, there were 45 landslide events affected physical, social, and economic damages. One approach to reduce disaster risk is building community resilience. This research aims to assess Landslide Community resilience in Bumiaji Sub-District. It is important to describe the characteristic of resilience level in each village. This research was done by using AHP to determine the weight of variables and indicators, then calculated with Baseline Resilience Indicators for Communities (BRIC) based on six variables: Physical, Social, Economic, Environmental, Community Capital, and Institutional. Data was collected by primary and secondary data. Primary data was collected by using interviews with experts from the government and the local community in Batu City, and secondary data was collected from the literature study. The results of AHP show that the highest priority of indicators is community preparedness, and the lowest priority is the number of health facilities. The weight of each factor was multiplied by the values of the indicators to assess the landslide community resilience index. The highest level of community resilience is Punten, caused by the high score in Physical, Economic, and Institutional aspects. The low level of resilience is Bumiaji and Pandanrejo Village. Both villages did not have regular mitigation programs to strengthen local communities, so the resilience level of community capital is low.

In 2017, land use was developed by 48% and undeveloped land by 52%. This study aimed to determine the characteristics of Surabaya City’s surface temperature distribution based on land cover characteristics and vegetation density in 2019. This study used a descriptive quantitative method with Overlay and Remote Sensing analysis techniques. The results of the analysis found that the dominant type of land cover in 2019 was undeveloped land (51%), and the vegetation density class was dominated by a very low density of green and a low density of green with a value of 0.4 − 0.25. In this case, the western part of Surabaya has a low surface temperature ranging from 23,2°C − 24°C, located in Pakal district. While the highest surface temperature (31°C − 41,1°C) is in the eastern part of Surabaya and the largest is in the Rungkut District. In conclusion, in the type of land cover and vegetation density class significantly affect the increase or decrease in surface temperature in Surabaya City.

Published: June 2023

Abstract
Tosari District is one of the tourist villages in Pasuruan Regency that has potential ecotourism because it is the gateway to Mount Bromo National Park. There are protected areas with the socio-cultural values of the Tenggerese Tribe. Ecotourism is an appropriate concept because it prioritizes sustainability, environmental conservation, and the uniqueness of tourist attraction objects. Developing sustainable rural infrastructure is the key to inclusive development to improve the concept of Ecotourism, thereby increasing economic resilience and engaging community productivity. This study aims to analyze the development of rural infrastructure that can improve ecotourism management. This study uses a qualitative approach to identify problems that are closely related to the provision of the physical infrastructure to reduce disaster levels, infrastructure that can boost agricultural productivity, and social infrastructure that needs to be established for ecotourism purposes. The need for infrastructure development is translated into the provision of waste management, disaster protection infrastructure, and improvement of road and communication infrastructure. The concept of a cultural approach requires carrying out tourism operations and preserving the culture of the Tengger tribe.

Published: June 2023

Abstract
Land conversion and food security are two related aspects that should be part of managing the system of cities and their surrounding regions. Rapid land conversion in fertile soil can be caused by hardship to get continuous water supply for agricultural system, competition over development sectors, or limited income from agricultural sectors. This paper investigates what challenges should be countered by the rice farming in rapidly urbanized region and what strategies should be applied to overcome the challenge. The study uses case study method with Sragen District for macro level analysis, and Gondang and Sragen, two sub-districts in Sragen District for micro level analysis. Interviews, survey with questionnaire, and focus group discussion are conducted for data collection The results show that Sragen District is experiencing decreasing number of agricultural workforce and contribution of agricultural sector to its GRDP. Low productivity of agricultural sector, especially of rice farming, due to small plot of rice field, high production cost, and difficulty to maintain continuous water supply for irrigation due to competition over water for irrigation and domestic uses are among the problems encountered by farmers. More strict regulation regarding variation of water function and uses, by multi stakeholders, and subsidy for agricultural input are required to secure the sustainability of rice farming in urbanized region that in the end will affect the sustainability of food and agriculture.
Initial steps towards a robotic solution for the manufacturing and assembly of thin-film space solar arrays
Authors: Carr John A , Thompson Furman , Bumbalough Austin 
Published: June 2023

Abstract
Print-assisted photovoltaic panel assembly (PAPPA), a novel printed electronic process presented herein, uses additive manufacturing to print flexible paneling components around commercial off-the-shelf thin-film solar cells. This builds a fully functional, flexible solar panel, suitable for space environments, via an automated process. Currently, thin-film space solar panels are manufactured via the compilation of piece parts by hand. In contrast PAPPA automates the labor-intensive paneling process. The advantages are twofold: (i) near-term: solar panel cost reduction alongside the enablement of very large-scale production and (ii) long-term: builds towards a capability for in-space solar panel manufacturing. Herein, details of the process, proof-of-concept functional testing, and implications for further development and application are presented.
From spectral analysis to hysteresis loops: a breakthrough in the optimization of magnetic nanomaterials for bioapplications
Authors: Barrera Gabriele , Allia Paolo , Tiberto Paola 
Published: June 2023

Abstract
An innovative method is proposed to determine the most important magnetic properties of bioapplication-oriented magnetic nanomaterials exploiting the connection between hysteresis loop and frequency spectrum of magnetization. Owing to conceptual and practical simplicity, the method may result in a substantial advance in the optimization of magnetic nanomaterials for use in precision medicine. The techniques of frequency analysis of the magnetization currently applied to nanomaterials both in vitro and in vivo usually give a limited, qualitative picture of the effects of the active biological environment, and have to be complemented by direct measurement of the hysteresis loop. We show that the very same techniques can be used to convey all the information needed by present-day biomedical applications without the necessity of doing conventional magnetic measurements in the same experimental conditions. The spectral harmonics obtained analysing the response of a magnetic tracer in frequency, as in magnetic particle spectroscopy/imaging, are demonstrated to lead to a precise reconstruction of the hysteresis loop, whose most important parameters (loop’s area, magnetic remanence and coercive field) are directly obtained through transformation formulas based on simple manipulation of the harmonics amplitudes and phases. The validity of the method is experimentally verified on various magnetic nanomaterials for bioapplications submitted to ac magnetic fields of different amplitude, frequency and waveform. In all cases, the experimental data taken in the frequency domain exactly reproduce the magnetic properties obtained from conventional magnetic measurements.
Evaluation of interlaminar shear strength of co-cured fiber-reinforced fabric composite structures by lap joint method
Authors: Jeon Jae-An , Lee Sang-Eui 
Published: June 2023

Abstract
Interlaminar shear strength (ILSS) indicates the resistance to interlaminar delamination of fiber-reinforced composite structures. The short beam shear (SBS) method has been commonly used for ILSS measurement, but unwanted failure modes can appear like a compressive or tensile failure in surface, and diagonal shear failure, causing poor measurement accuracy. The lap joint method has advantage that leading to a clear measurement of the shear strength. This paper proposed the lap joint method for extracting ILSS values of co-cured carbon or glass fiber-reinforced fabric composites (CFRC or GFRC) by minimizing the discrepancy between the experiment and finite element analysis of ILSS test. The lap joint method can compensate for the shortcomings of the SBS method. The calculated ILSS based on the lap joint method (LJ-ILSS) with correction factors showed similar values to the ILSS values by SBS method (SBS-ILSS) done by our work and other works of literature. Therefore, the proposed lap joint method has shown potential as a method to measure ILSS of the co-cured fiber-reinforced fabric composites, but also it can be extended to other types of fiber-reinforced composites.
A theoretical and deep learning hybrid model for predicting surface roughness of diamond-turned polycrystalline materials
Authors: He Chunlei , Yan Jiwang , Wang Shuqi , Zhang Shuo , Chen Guang , Ren Chengzu 
Published: June 2023

Abstract
Polycrystalline materials are extensively employed in industry. Its surface roughness significantly affects the working performance. Material defects, particularly grain boundaries, have a great impact on the achieved surface roughness of polycrystalline materials. However, it is difficult to establish a purely theoretical model for surface roughness with consideration of the grain boundary effect using conventional analytical methods. In this work, a theoretical and deep learning hybrid model for predicting the surface roughness of diamond-turned polycrystalline materials is proposed. The kinematic–dynamic roughness component in relation to the tool profile duplication effect, work material plastic side flow, relative vibration between the diamond tool and workpiece, etc, is theoretically calculated. The material-defect roughness component is modeled with a cascade forward neural network. In the neural network, the ratio of maximum undeformed chip thickness to cutting edge radius R
TS, work material properties (misorientation angle θ
g and grain size d
g), and spindle rotation speed n
s are configured as input variables. The material-defect roughness component is set as the output variable. To validate the developed model, polycrystalline copper with a gradient distribution of grains prepared by friction stir processing is machined with various processing parameters and different diamond tools. Compared with the previously developed model, obvious improvement in the prediction accuracy is observed with this hybrid prediction model. Based on this model, the influences of different factors on the surface roughness of polycrystalline materials are discussed. The influencing mechanism of the misorientation angle and grain size is quantitatively analyzed. Two fracture modes, including transcrystalline and intercrystalline fractures at different R
TS values, are observed. Meanwhile, optimal processing parameters are obtained with a simulated annealing algorithm. Cutting experiments are performed with the optimal parameters, and a flat surface finish with Sa 1.314 nm is finally achieved. The developed model and corresponding new findings in this work are beneficial for accurately predicting the surface roughness of polycrystalline materials and understanding the impacting mechanism of material defects in diamond turning.
