Abstract
A novel single-layer graphene-based structure is designed in this article. This structure consists of two graphene strips and two graphene blocks. The components of this structure generate two bright modes and one dark mode in the terahertz region, and these three modes undergo destructive interference, leading to the phenomenon of double plasmonic induced transparency. The graphene of this structure has continuity, and the Fermi level can be adjusted by adjusting the bias voltage applied to the structure. Compared with those discontinuous structures, it is easier to achieve tuning function. The structure uses the finite-difference time-domain for data simulation, uses the coupled mode theory for theoretic calculation, and compares the transmission spectra obtained by the two methods. Through observation, it can be found that the frequency positions of the peaks and dips of the simulated transmission spectrum increase with the increase of the Fermi level, showing a perfect linear relationship, which indicates that this structure has great prospects in the modulator. In addition, the structure has achieved good results in the slow light effect, and after measurement, the peak values of group index and group delay can reach up to 380 and 0.241 ps, respectively. By utilizing these advantages, this structure can provide more possibilities for the development and research of slow light fields.

Abstract
Silver-gold alloy nanoparticles were grown using heat treatment of soda-lime glass slides with depercolated gold film subjected to silver-to-sodium ion exchange. Varying the regime of the heat treatment allows one to control the proportion of silver in the nanoparticles and adjust the spectral position of their local surface plasmon resonance (LSPR) in the spectral range between the resonances of gold and silver nanoparticles. The position of LSPR in gold nanoparticles can be shifted by 15% via their dilution by silver in 50 wt % concentration. This shift is accompanied by only a 3% decrease in HeLa cell viability on the slides with alloy nanoparticles on the surface and by a slight decrease in the cell functionality/adhesion (FA) that show the biocompatibility of these nanoparticles. On the contrary, a notable decrease in the viability and ∼100% drop of FA were registered for the slides with purely silver nanoparticles.

Abstract
Hydrogen–disproportionation–desorption–recombination (HDDR) Nd–Fe–B magnetic powders are promising to prepare bulk anisotropic magnets, but high magnetic performance has not been achieved due to the absence of an Nd-rich phase in the powder and the low degree of orientation of the bulk magnets. In this study, an alternative process of pre-orientation sintering via magnetic alignment followed by spark plasma sintering was proposed to prepare the precursor of hot-deformation (HD) magnets, and a high maximum energy product of 294 kJ m−3 was achieved in the HD magnet with a relatively low height reduction of 35%, then an improved coercivity of 1107 kA m−1 could be obtained followed by a grain boundary diffusion of Pr40Tb30Al20Cu10. Microstructure analysis indicates that pre-orientation of HDDR powders facilitates grain rotation and alignment during the HD process, thereby reducing the minimum deformation ratio. It helps to obtain the deformed grains with lower shape anisotropy and smaller grain size, enabling a good compatibility of magnetic and mechanical behaviors. In-situ Lorentzian transmission electron microscopy results show that the magnetic domains have been strongly fixed by the thick intergranular RE-rich phase and the fully Tb-diffused grains, which contributes to the improved coercivity after grain boundary diffusion. This study provides a guiding significance for the preparation of the anisotropic Nd–Fe–B HDDR magnets with optimized performance.

Published: December 2023

Abstract
Fermi-level pinning caused by the kinetic damage during metallization has been recognized as one of the major reasons for the non-ideal behavior of electrical contacts, forbidding reaching the Schottky–Mott limit. In this manuscript, we present a scalable technique wherein Indium, a low-work-function metal, is diffused to contact a few-layered MoS2 flake. The technique exploits a smooth outflow of Indium over gold electrodes to make edge contacts to pre-transferred MoS2 flakes. We compare the performance of three pairs of contacts made onto the same MoS2 flake, the bottom-gold, top-gold, and Indium contacts, and find that the Indium contacts are superior to other contacts. The Indium contacts maintain linear I–V characteristics down to cryogenic temperatures with an extracted Schottky barrier height of ∼2.1 meV. First-principle calculations show the induced in-gap states close to the Fermi level, and the damage-free contact interface could be the reason for the nearly Ohmic behavior of the Indium/MoS2 interface.

Authors: Aier K Moatemsu , Dhar Jay Chandra 
Published: December 2023

Abstract
A UV–visible broadband photodetector (PD) based on single walled carbon nanotube (SWCNT)/Zinc oxide nanowire (ZnO NW) hybrid is being reported. This work focuses on designing a stable, fast, efficient and reliable hybrid broadband PD by surface modification of ZnO NWs using SWCNT. The study shows that spectral response of the hybrid heterostructure (HS) spans beyond the UV spectrum and into the visible region which is due to the integration of SWCNTs. Photoluminescence (PL) study reveals surface plasmon (SP) mediated resonance phenomenon resulting in an increase in PL intensity. High nanotube charge carrier mobility and conductivity allows the hybrid HS to attain high values of spectral responsivity (R
λ = 187.77 A W−1), external quantum efficiency (EQE = 5.82 × 104%), specific detectivity (D* = 7.04 × 1011 Jones) and small noise equivalent power (NEP = 4.77 × 10−12 W) values for the SWCNT/ZnO NW hybrid HS. The device also gives quick rise (t
rise = 0.43 s) and fall (t
fall = 0.60 s) time values.

Published: December 2023

Abstract
NH3 is widely existed in the environment and is closely associated with various health issues. Additionally, detecting the small amounts of NH3 exhaled by patients with liver and kidney diseases offers potential opportunities for painless early disease diagnosis. Therefore, there is an urgent need for a convenient, rapid, and highly sensitive real-time NH3 monitoring method. This work presents a high-performance NH3 sensor based on olfactory receptor-derived peptides (ORPs) on a pyramid silicon nanowires (SiNWs) structure substrate. First, we successfully fabricated the pyramid-SiNWs structure on a silicon substrate using a chemical etching method. Subsequently, by dehydrative condensation reaction between the amino groups on APTES and the carboxyl groups of ORPs, ORPs were successfully immobilized onto the pyramid-SiNWs structure. This methodology allows the ORPs sensor on the pyramid-SiNWs substrate to detect NH3 as low as 1 ppb, which was the reported lowest limit of detection, with a higher response rate compared to ORPs sensors on flat SiNWs substrates. The sensors also exhibit good sensitivity and stability for NH3 gas detection. The results show the feasibility and potential applications of ORPs-pyramid-SiNWs structure sensors, in the fields of food safety, disease monitoring, and environmental protection, etc.
The ground state, localization, and chiral edge dynamics of a three-legged bosonic magnetic ladder

Published: December 2023

Abstract
Three-legged bosonic/fermionic magnetic ladder, reproducing the main features of magnetic lattice systems, is an ideal model to study the edge-bulk coupling and chiral edge dynamics, which are a hallmark of quantum Hall physics. Here, the ground state transition, localization, and chiral edge (bulk) states of an interacting three-legged bosonic magnetic ladder are studied analytically and numerically. When the system is in a quasi-steady state, using variational analysis, the threshold for the transition from zero momentum state to plane wave state is obtained. The energy spectrum, the ground state diagram, the chiral current of the system are presented, and the chiral current reversal at the state transition point is observed. Furthermore, the localization and its stability in the system are discussed, and rich localized phenomena (diffusion, breather, soliton, and self-trapping) are predicted. Stable soliton/breather prefers to form an edge state, while the self-trapping is favorite to form a bulk state, i.e. localized edge and bulk states are obtained. Particularly, for the unstable soliton in the ground state or metastable state, different kinds of chiral edge/bulk state and edge-bulk coupling are observed. The stability of the localized states, the edge-bulk coupling characteristics, and the chirality of the system depend on the energy band structure of the system. Additionally, a controllable transition between localized edge state and bulk state is realized by quenching the soliton state. We proposed a theoretical evidence to design and manipulate edge-bulk coupling and different kinds of localized/chiral edge (bulk) states in three-legged bosonic magnetic ladder.

Published: December 2023

Abstract
In terms of survival, resilience serves as an example of choice when confronted with situations where opportunities to choose are lacking. Thus, in such conditions, it becomes necessary to adapt to the incompatible circumstances being encountered. The traditional settlement community of Bugis Wajo holds “ulayat rights”, enabling them to thrive for generations in the vicinity of Tempe Lake. One of them, the traditional communities in Wette Hamlet in Lautang Village must grapple with annual flooding of 2–3 meters during the rainy season due to river water overflow from Tempe Lake. This flooding phenomenon stands as a testament to the unique ability of local traditional communities to adjust to normal conditions during dry seasons and adapt to the rainy seasons, allowing them to endure in their daily communal pursuits. This research employed quantitative descriptive methods and utilized eight variables, which were subsequently assigned scores to quantify resilience. Based on the results and the ensuing discussion of the analysis, it is evident that secure housing holds immense value in bolstering community resilience. There are high values in community resilience concerning community capacity, social capital, connectedness, and access to clean water. Meanwhile, there is a moderate level of community resilience when considering aspects such as disaster preparedness, livelihoods, and health. In conclusion, the analysis identifies a high degree of community resilience within the traditional community of Wettee Hamlet in Lautang Village.

Published: December 2023

AbstractBojonegoro is a regency in East Java province with a population of 1,322,474 (BPS, 2022) and high population density. Population growth is strong, and demand for land is increasing. Increased human activity leads to land conversion, which could impact regional development. The objectives of this study are to: 1) Analyze the dynamics of land cover change, 2) Compare the SDI (Sub-district Development Index) scores of 2008 and 2020 in Bojonegoro Regency, and 3) Analyze the factors affecting the level of Regional development in Bojonegoro Regency. The methods used are overlay (GIS analysis), scale plot analysis, and geographically weighted regression (GWR) analysis. The most significant land cover change occurred in forest cover, with the area decreasing from 99,815 hectares (2000) to 84,845 hectares (2020), while the built-up area increased from 12,665 hectares (2000) to 22,901 hectares ( 2020). Bojonegoro sub-district has the highest SDI of 44,043 (2008) and 44,917 (2020) because it has the largest population and become a capital district and central business district (CBD). Based on the results of the GWR analysis, the highest local R2 is located in the eastern part of the Regency. In contrast, the lowest local R2 is located in the western administrative district of Bojonegoro Regency. The results show that the driving forces influencing regional development in Bojonegoro Regency vary spatially.

Published: December 2023

Abstract
The issue of microplastics has garnered significant attention in light of their potential environmental hazards and possible health effects on higher trophic organisms and humans. However, the available information is restricted and knowledge about the interaction between microplastics in aquatic sediments and the microplastic-related impacts of aquaculture activities, and this area has not yet been adequately researched. This research looks at the occurrence and properties of microplastics in the bed sediment from Perna veridis aquaculture activity areas, in the Strait of Johor, Malaysia. Bed sediments were collected in replicates from five sampling sites using a box corer (Wildco). The extracted organic matter was digested with 30% hydrogen peroxide (H2O2) before being separated using NaCl and ZnCl solutions. The inspection of plastic debris was conducted via a Stereomicroscope (HSZ-600) at magnifications ranging from 40x to 45x and considered according to morphology, size, and colour. Microplastic polymers were validated using Attenuated Total Reflection Fourier Transferred Infra-Red (ATR-FTIR) spectroscopy. The sediment samples exhibited a varying range of microplastic abundance, with values ranging from 29 to 60 particles/kg.d.w. Microplastics within the size range of 101-500μm (63%) predominated in all samples collected, with fragments (79%) and fibres (18%) being the main morphologies of MPs found. The dominant particles found in the sediment were polypropylene (PP) and polyamide. The findings suggest that aquaculture practises may have an impact on the presence of microplastics (MPs) in bottom sediment, as these locations are well-known aquaculture areas for Perna veridis.

Published: December 2023

Abstract
Municipal Solid Waste Management (MSWM) is a significant challenge in developing countries, including Indonesia, where landfilling is the predominant waste treatment method. This study examines the case of Makassar City, where landfilling is still in use while composting is utilized to a limited extent. The research aims to evaluate and compare the environmental impact with three alternative scenarios involving biological treatment and life cycle assessment (LCA) processing. The scenarios were examined: Business as Usual Scenario (BaU), Landfill and Composting, Landfill and Anaerobic Digestion, Landfill, Composting, and Anaerobic Digestion. The study considers waste transportation, landfilling, anaerobic digestion, and composting within its system boundary, using annual waste processing as the functional unit. Environmental impacts assessed include global warming, acidification, and eutrophication. The findings indicate that the BaU scenario has the highest environmental impact, particularly regarding global warming, with 8,436,685.61 kg CO2eq/year emissions. On the other hand, alternative scenario 3, which incorporates landfill management, composting, and anaerobic digestion, shows a relatively lower Global Warming Potential (GWP) emission. However, further measures are needed to effectively reduce emissions, such as implementing a cover for the compost pile and arranging the mixing.

Published: December 2023

Abstract
Coastal tourism is a tourism market segment that is increasing in popularity. The said increase happened due to coastal destinations’ ability to give visitors a tranquil and isolated atmosphere. This trend often triggered excessive coastal developments that could strain and cause irreparable damage to the local coastal ecosystem. Previous findings stated that a local environmental carrying capacity assessment needs to be formulated before a physical development can be exercised. Sekotong is a district in West Lombok that has the potential to be developed as a coastal tourism hub. It is located by the Lombok Strait that has good surfing waves and a beautiful seascape. This region is projected to experience a drastic visitor increase in the coming years. These potentials and increasing visitor number projections could attract physical development interests in the future. This study aims to assess local environmental carrying capacity, especially regarding coastal tourism activities. A quantitative approach utilizing statistical data and remote sensing tools is done to assess the physical and real carrying capacity models. The assessment shows that the study area can endure tourism development that is aimed to satisfy 3.087,57 individuals. This number represents the local ecosystem’s limit to endure future development plans and is expected to be referenced in future physical development plans in Sekotong. This study is also hoped to contribute to local coastal environment sustainability.

Abstract
The development of world cultural heritage areas into tourist attractions often faces land conversion problems, social and environmental pressures. The phenomenon of migration, exclusivity and loss of local characteristics cannot be avoided. Therefore, studies are needed that are able to find better solutions for developing world cultural heritage areas in order to achieve sustainability. This research aims to examine Subak’s participation in preserving the world cultural heritage area in Bali and develop appropriate strategies for the sustainability of this site. Data was analyzed using the SWOT method. The research results show that farmer participation in preserving world heritage sites is at a high level. There are several weaknesses in developing cultural heritage areas in Jatiluwih, namely the lack of variety of tourist attractions and climate change which threatens rice planting patterns in rice fields. Even though farmers feel the impact of climate change, they have not yet made changes to planting patterns as an effort to adapt to climate change so that it will have an impact on the quality of crops in the future. Innovative and inclusive spatial models must be based on climate change, IoT developments and the image of the subak world cultural heritage site.
