Published: March 2023

AbstractThe increasing lithium-ion battery production calls for profitable and ecologically benign technologies for their recycling. Unfortunately, all used recycling technologies are always associated with large energy consumption and utilization of corrosive reagents, which creates a risk to the environment. Herein we report a highly efficient mechanochemically induced acid-free process for recycling Li from cathode materials of different chemistries such as LiCoO2, LiMn2O4, Li(CoNiMn)O2, and LiFePO4. The introduced technology uses Al as a reducing agent in the mechanochemical reaction. Two different processes have been developed to regenerate lithium and transform it into pure Li2CO3. The mechanisms of mechanochemical transformation, aqueous leaching, and lithium purification were investigated. The presented technology achieves a recovery rate for Li of up to 70% without applying any corrosive leachates or utilizing high temperatures. The key innovation is that the regeneration of lithium was successfully performed for all relevant cathode chemistries, including their mixture.

Published: March 2023

AbstractStudying the surface chemistry of functionalized cellulose nanofibrils at atomic scale is an ongoing challenge, mainly because FT-IR, NMR, XPS and RAMAN spectroscopy are limited in sensitivity or resolution. Herein, we show that dynamic nuclear polarization (DNP) enhanced13C and15N solid-state NMR is a uniquely suited technique to optimize the drug loading on nanocellulose using aqueous heterogenous chemistry. We compare the efficiency of two conventional coupling agents (DMTMM vs EDC/NHS) to bind a complex prodrug of ciprofloxacin designed for controlled drug release. Besides quantifying the drug grafting, we also evidence the challenge to control the concurrent prodrug adsorption and to optimize washing procedures. We notably highlight the presence of an unexpected prodrug cleavage mechanism triggered by carboxylates at the surface of the cellulose nanofibrils.

Published: March 2023

AbstractA “synthetic minimal cell” is considered here as a cell-like artificial vesicle reproduction system in which a chemical and physico-chemical transformation network is regulated by information polymers. Here we synthesise such a minimal cell consisting of three units: energy production, information polymer synthesis, and vesicle reproduction. Supplied ingredients are converted to energy currencies which trigger the synthesis of an information polymer, where the vesicle membrane plays the role of a template. The information polymer promotes membrane growth. By tuning the membrane composition and permeability to osmolytes, the growing vesicles show recursive reproduction over several generations. Our “synthetic minimal cell” greatly simplifies the scheme of contemporary living cells while keeping their essence. The chemical pathways and the vesicle reproduction pathways are well described by kinetic equations and by applying the membrane elasticity model, respectively. This study provides new insights to better understand the differences and similarities between non-living forms of matter and life.
Locating real-time water level sensors in coastal communities to assess flood risk by optimizing across multiple objectives
Authors: Tien Iris , Lozano Jorge-Mario , Chavan Akhil 
Published: March 2023

AbstractCoastal communities around the world are experiencing increased flooding. Water level sensors provide real-time information on water levels and detections of flood risk. Previous sensor installations, however, have relied on qualitative judgments or limited quantitative factors to decide on sensor locations. Here, we provide a method to optimally place real-time water level sensors across a community. We utilize a multi-objective optimization approach, including traditional measures of sensor network performance such as coverage and uncertainty, and new flood-specific parameters such as hazard estimations (flood likelihood, critical infrastructure exposure), serviceability (sensor accessibility), and social vulnerability (socio-economic index, vulnerable residential communities index). We propose a workflow combining quantitative analyses with local expertise and experience. We show the method is able to reduce the set of possible new sensor locations to just 1.3% of the full solution set, supporting effective and feasible community decision-making. The method also supports sequential expansion of a sensor network, creating a network that provides detailed and accurate real-time water level information at the hyperlocal level for flood risk assessment and mitigation in coastal communities.

Authors: Zidane Miriam , Theurich Sebastian , Schlaak Max 
Published: March 2023

Zusammenfassung
Einleitung Die Inzidenz von Adipositas nimmt weltweit stetig zu. Übergewicht und Adipositas werden als mögliche Risikofaktoren für verschiedene Krebserkrankungen, einschließlich des malignen Melanoms, diskutiert. Dieser Review stellt die Evidenz zu der Assoziation zwischen Adipositas und dem malignen Melanom dar.
Methodik Selektive Literaturrecherche.
Ergebnisse Obwohl verschiedene Erklärungsansätze für eine mögliche Assoziation von Adipositas und dem malignen Melanom existieren, sind diese nicht vollständig bekannt und weiterhin Gegenstand der Forschung. Die Evidenz zur Assoziation zwischen Adipositas und Melanom-Outcomes für Patienten ohne Systemtherapie ist gering. Für Patienten mit Systemtherapie gibt es Evidenz, die einen protektiven Effekt unter Immuntherapien und zielgerichteten Therapien beschreibt.
Schlussfolgerung Insgesamt gibt es zu der Assoziation zwischen dem malignen Melanom und Adipositas nicht ausreichend Evidenz, um zu schlussfolgern, ob Adipositas einen unabhängigen protektiven Effekt hat oder ein Risikofaktor für die Entstehung von Melanomen darstellt. Weitere Forschung ist erforderlich, um das Wissen über diesen möglichen Zusammenhang zu vertiefen.

Published: March 2023

AbstractOver the past two years, the outbreak of coronavirus disease of 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has centralized the interest of the health care systems and the scientific world. The majority of COVID-19-infected individuals recover fully. However, about 12–50% of patients experience various mid- and long-term effects after recovering from the initial illness. These mid- and long-term effects are collectively known as post-COVID-19 condition or 'long-COVID'. In the coming months, the long-term consequences of COVID-19 on the metabolic and endocrine systems may expect to rise and pose a global healthcare challenge. This review article discusses the possible metabolic and endocrine complications of long-COVID and the relevant research findings.

Abstract
Objective Mandibular fracture is the most common maxillofacial fracture accompanied by complaints of malocclusion and pain. This causes a decrease in the quality of life. Mandibular fracture management can be done with open reduction and internal fixation or intermaxillary fixation. The Oral Health Impact Profile (OHIP 14) and the General Oral Health Assessment Index (GOHAI) were used to evaluate the quality of life after surgical treatment based on the distribution of age, sex, type of neglect, and surgical management.
Materials and Methods This research is an analytic study with an analytical observational method with total sampling. The total sample used was 15 patients during the 2006 to 2020 period. The results of this study were scored, and then, the data were processed using the eta test.
Results The results of the study based on the OHIP 14 parameters showed the results of each distribution, namely, age: p = 0.154, gender: p = 0.080, neglected type: p = 0.080, and management: p = 0.419. Meanwhile, the GOHAI parameters showed the results of each distribution, namely, age: p = 0.105, gender: p = 0.356, neglected type: p = 0.356, and management p = 0.286. The results of this distribution showed that there was no significant difference between patients' quality of life based on age, sex, neglected type, and treatment using both OHIP 14 and GOHAI parameters.
Conclusions The results obtained in this study using characteristics of age, gender, type of fracture, type of neglect, and management did not have a significant effect on the level of patient satisfaction after surgery, using both OHIP 14 and GOHAI questionnaires.

Abstract
FOXP1 encodes a transcription factor involved in tissue regulation and cell-type-specific functions. Haploinsufficiency of FOXP1 is associated with a neurodevelopmental disorder: autosomal dominant mental retardation with language impairment with or without autistic features. More recently, heterozygous FOXP1 variants have also been shown to cause a variety of structural birth defects including central nervous system (CNS) anomalies, congenital heart defects, congenital anomalies of the kidney and urinary tract, cryptorchidism, and hypospadias. In this report, we present a previously unpublished case of an individual with congenital diaphragmatic hernia (CDH) who carries an approximately 3.8 Mb deletion. Based on this deletion, and deletions previously reported in two other individuals with CDH, we define a CDH critical region on chromosome 3p13 that includes FOXP1 and four other protein-coding genes. We also provide detailed clinical descriptions of two previously reported individuals with CDH who carry de novo, pathogenic variants in FOXP1 that are predicted to trigger nonsense-mediated mRNA decay. A subset of individuals with putatively deleterious FOXP4 variants has also been shown to develop CDH. Since FOXP proteins function as homo- or heterodimers and the homologs of FOXP1 and FOXP4 are expressed at the same time points in the embryonic mouse diaphragm, they may function together as a dimer, or in parallel as homodimers, to regulate gene expression during diaphragm development. Not all individuals with heterozygous, loss-of-function changes in FOXP1 develop CDH. Hence, we conclude that FOXP1 acts as a susceptibility factor that contributes to the development of CDH in conjunction with other genetic, epigenetic, environmental, and/or stochastic factors.
Thickness dependent microstructural and magnetic studies of iron embedded PVA nanocomposite films
Authors: Joshi Aruna , Mukherjee G. S. , Gupta Mukul , Banerjee M. 
Published: March 2023

This paper presents the structural and magnetic properties of polyvinyl alcohol/iron (PVA/Fe) nanocomposite films. Iron (Fe) films of different thicknesses were deposited on a PVA substrate using ion beam sputtering. The Fe nanoparticle layer thickness ranges from 3 to 50 nm on the PVA substrate. Grazing incidence x-ray diffraction has been carried out to study the structural behavior of the prepared films. An atomic force microscope records the indicated remarkable change in the roughness of the nanocomposite film as a result of initiation of vertical growth of sputtered Fe nanoparticles.Magneto-optic Kerr effect (MOKE) magnetometry and MOKE spectroscopy have been employed to evaluate the magnetic property and simultaneously study the real time growth of the magnetic domain structure for both 0° and 90° azimuthal angles. MOKE microscopic images indicated the magnetization reversal commensurate with the hysteresis loop of the nanocomposites. All the films show soft ferromagnetic behavior. Gradual development of the domain structure is observed in the MOKE micrograph with the increase in the thickness of Fe nanoparticle deposition. Ex situ magnetic force micrographs of the magnetic domain structures supported the observation of MOKE microscopic studies, which indicated switching of in-plane magnetization to out-of-plane magnetization near an Fe nanoparticle deposition thickness of 40 nm. The PVA matrix appears to be an effective material to support the growth of magnetic properties in the PVA/Fe nanocomposite system. The evolution of Fe nanostructures on PVA and the resulting magnetic behavior have been discussed.

Published: March 2023

This study adopted molecular dynamics to investigate the influence of C28H58 mass fraction on the structure and phase change of C28H58/C22H46 n-alkane mixtures at different temperatures; systematically analyzed the C–H and C–C bond lengths, changes in the H–C–H bond angle and C–C–C–C torsion angle, and energy conversions within the mixture during heating of C28H58/C22H46 n-alkane mixtures; calculated the self-diffusion coefficient (D) by combining the Einstein relation and mean squared displacement; and determined the phase change temperature of each mixture according to the relationship between D and temperature. The results show that, at 280 K, changing the mass fraction of C28H58 does not affect the C–H and C–C bond lengths and the H–C–H bond angle. At 350 K, the C–H bond length decreases with the increase in the mass fraction of C28H58, the C–C bond length increases slightly when the mass fraction is 65.2% and remains unchanged for other mass fractions, and the H–C–H bond angle slightly decreases. With an increase in temperature, the peak intensity of the stretched conformation at ±180° gradually decreases, while the peak of the twisted conformation appears around ±70°, and the degree of twist of the C–C–C–C dihedral angle in the mixture increases. The phase change temperature begins to increase slowly with the increase in the mass fraction of C28H58, and the phase change temperature increases rapidly when the mass fraction exceeds 65.2%. The kinetic and potential energies of the mixture tend to increase with the increasing mass fraction of C28H58.

There have been continual attempts to identify alternatives to increase the agricultural output to improve the living standards of farmers, meet the current demand, and promote sustainability in commercial agriculture. Within this paradigm, low-temperature plasma (LTP) treatments have piqued the attention of investigators and are presently being extensively researched in the agriculture sector. A preliminary study was conducted on mustard seeds (Brassica nigra) to examine the potential of LTP in agriculture to enhance germination and productivity. The seeds were subjected to LTP treatment for 1 to 4 min in an argon environment (11.7 kV, 50 Hz, and Q = 3 L/min) at atmospheric pressure. The germination and growth parameters of the untreated and treated seeds were calculated on the 16th day of the seeds’ germination and compared. All germination and growth-related parameters were found to be improved in LTP-exposed seeds up to 3 min. However, the germination and growth-related parameters deteriorated in 4-min LTP-treated seeds compared to those of control and other treatment time seeds. The water contact angle and scanning electron micrograph images clearly indicated that there is a significant change in the seed coat after being exposed to LTP for a specific time period. The treated seed’s texture was significantly rougher than that of the control, which is directly related to the hydrophilicity of seeds. The findings of this study suggest that using seeds exposed to LTP for a suitable time results in a considerable increase in the germination percentage of sown seeds while also hastening seedling growth and development.
The effectivity of the law protection on the sustainability of Yellow-Crested Cockatoos (cacatua sulphurea) in Indonesia
Authors: Purwanto E , Susanto  
Published: March 2023

AbstractYellow-crested cockatoos (Cacatua sulphurea) is one of 435 species protected by law and of 512 endemic species in Indonesia. This study aimed to assess whether law enforcement to protect the Yellow-crested cockatoos (Cacatua Sulphurea) from extinction was maximal. This research method applied normative juridical research, in which the court decision is the primary legal material. The later decision of the East Kalimantan High Court Number 6/PID/2018/PT.SMR is the primary legal data or materials that be analyzed in this study. The results of this study assess that law enforcement to protect the sustainability of Yellow-crested cockatoos in Indonesia is still not optimal. Furthermore, law enforcement related to corporate violations that are more dangerous to the extinction of these species is still a problem that needs to be studied further. This study will contribute to law enforcement realizing that the protection of endemic species in Indonesia relies heavily on their firmness and fair decisions according to law. Socialization related to the law on the Conservation of Biological Natural Resources and Its Ecosystems to the people needs to be improved. Most likely, people are still not aware of protected species because they are on the verge of extinction or endemic. The research limitation of the study is that the study analyzes high court decisions that do not yet have permanent legal force (Inkracht). There is still an opportunity for both the convict and the public prosecutor to appeal to the Supreme Court of Cassation if the court’s decision is deemed not right.

Abstract
Occurrence of drought is due to climate variability and climate change. Drought affected on agriculture, economic, social and environment. The suitable technique in detecting and monitoring drought events can provide useful information for prevention and mitigation planning from their impacts. The study objective was to investigate the change of rainfall and temperate as well as find out the appropriate drought index and its trend for the Northern part of Thailand. These drought indices were calculated by using meteorological data during 1951-2020 of 10 stations comparing with historical drought records between January and May during 2011-2016 in the same areas. The drought indices consisted of Standardized Precipitation Index (SPI), Deciles index and Moisture Available index (MAI) at 1-, 3- and 6-month timescales and Palmer Drought Severity Index (PDSI). It was found that PDSI was the most appropriate index. The Mann-Kendal test was used to investigate the trend of rainfall, temperature and PDSI. The results showed an increasing of temperature. There was no trend of drought intensity for long-term (40 years) periods but was in 4 stations for short-term (20 years) periods. The PDSI can be used for drought monitoring and predicting in advance by using numerical weather prediction products.

Abstract
Mineralogical and geochemical investigations were carried out to determine the characteristics of limestone in the Wonosari Formation and to suggest its depositional environment and a preliminary study for the properties of Portland Cement. The study was conducted at Ponjong Area, Gunungkidul Regency, Daerah Istimewa Yogyakarta, Indonesia. The outcrop in this study area is composed of Wonosari layered limestone. Based on the facies interpretation in the research area, there are three depositional units: packstone, wackstone, and grainstone. This area’s depositional environment is the back reef lagoon and sand apron zones that are not related to the open sea. According to XRF data, limestone showed a reasonably high composition of CaO compounds, about 53.78% - 59.09%. Most limestone samples were classified as good quality as Portland Cement Raw Material due to CaO content >49%. The MgO, SiO2, Al2O3, Fe2O3, SO3, K2O, Na2O, TiO2, and P2O5 compounds also fulfil the Indonesian National Standard (SNI-15-2049-2004). Geochemical content shows limestone has a higher grain percentage than the matrix. The utilization of limestone in research area are expected to be a reference for the development of natural resources in the future that pay attention to the environment for mutual sustainability.
