Published: January 2025

Fossil assemblages preserved in nodules of the methane-seep deposits, recognized by Haig et al. (2022) in the lower Permian (Cisuralian, Sakmarian stage) of the Irwin Basin, include representatives of three ecosystems: seep, pelagic, and coastal plain. The seep biota, new to the Australian Permian, consists of small thickets with a framework of tubeworms, less common algal-like Tubiphytes, and problematica (? algae or sponges). Other components include microbial mats, macrophyte alga Litostroma (first report from Gondwana); foraminifers; sponges with siliceous monaxon spicules; a new group of small, lightly ornamented rostroconchs; microgastropods and rare larger types; ostracods and minute scolecodonts from polychaete jaws. Elements of the pelagic ecosystem are ammonoids (abundant in enclosing shale) and marine microphytoplankton. Probable vertebrate bone (possibly amphibians) and diverse spores and pollen from land plants come from the adjoining coastal plain. The surrounding mudstone lacks benthic macrofauna but includes an unusual assemblage of siliceous agglutinated foraminifers. The seeps were oases of high organic productivity on an otherwise barren muddy seafloor. The Holmwood Shale’s seep carbonates have close similarities to modern seep deposits in shallow-marine settings.
Statistical accounting of religious groups: some data on the history of Old Believer statistics in the Olonets and Arkhangelsk provinces
Authors: Kuznetsova Natalya Yurevna 
Published: January 2025

The article examines the features of the statistics of accounting for religious groups in the Russian Empire on the example of the Old Believer community in the Olonets and Arkhangelsk provinces in the XIX century. A brief digression is made into the history of the formation of statistics in Russia within the framework of the XIX century. This allows you to see on what data the registration of believers took place, as well as who and how it was conducted. Within the framework of the study, special cases of statistical accounting of Old Believers in the Olonets and Arkhangelsk provinces are considered, demonstrating the difficulties encountered in this matter. In particular, statistical tables are provided for a number of counties, which show discrepancies in the data. Such discrepancies became possible due to the difference in approaches to accounting for Old Believers among officials, the police and the clergy. The research is based on the analysis of archival data from the National Archive of the Republic of Karelia and the State Archive of the Arkhangelsk region. Materials from the funds of the provincial statistical committees are compared and compared. The author comes to the conclusion that despite all the standardization of state statistics and the importance of the issue of accounting for religious groups of the population, the statistics of the Old Believers in the northern provinces had a number of difficulties. They concerned both the field accounting itself and the data consolidation into single tables. In particular, the question of who more accurately counted representatives of other religious groups that do not belong to official Orthodoxy remained open. The statistical tables provide data from both the police and the priests of local parishes. They are often very different. Another point that the author comes to in the study is the importance of comparing data over several years and the moment they are reflected in statistics. The research was carried out at the expense of a grant from the Russian Science Foundation No. 23-28-10260, https://rscf.ru/project/23-28-10260 / conducted jointly with the Republic of Karelia with financing from the Venture Capital Investment Fund of the Republic of Karelia (FVI RK).

Published: January 2025

This study aims to: 1) analyse the utilization direction of the Regional Spatial Plan (RTRW) and its influence on land use change in Buntulia Sub-district, Pohuwato Regency; 2) analyse the pattern of land use change in Buntulia Sub-district during the period 2012-2024. This research uses a quantitative descriptive method with a spatial approach through ArcGIS 10.8 software. Data was obtained from overlaying the 2012 and 2024 land use maps and analysing the transition matrix to see the pattern of land use change. The results showed that the implementation of the RTRW direction in Buntulia Sub-district was not optimal. Of the total area of 43,422.71 hectares, 1,877.85 hectares of land use is not in accordance with the RTRW direction. Significant land use change occurred in primary and secondary forest areas that were converted into plantations, mixed agriculture, and open land. Analysis of land use change patterns for the 2012-2024 period revealed an increase in the area of plantations by 231.57 hectares and mixed agriculture by 980.44 hectares, while the area of primary and secondary forests decreased significantly. The conclusion of this study shows that the dynamics of land use change in Buntulia Sub-district are influenced by a lack of compliance with the RTRW, population growth, and economic development pressures. Strengthening spatial planning policies, stricter supervision, and mitigation are needed to minimise the environmental impact of uncontrolled land use change.

An investigation was carried out to study the micronutrient status of rice-growing soils of the delta area of Krishna district in Andhra Pradesh to know the potential of these soils to supply micronutrients to rice crops. For this, six profiles viz., Vemulamada (P1), Kothapalli (P2), Velivelu (P3), Nangegadda (P4), Penamaluru (P5), and Ganguru (P6) were studied covering the major cereal-maize/ cereal- pulse growing areas. The soils were near neutral to strongly alkaline in reaction, non-saline, and low in organic carbon content. The weighted average of DTPA extractable zinc, copper, iron, and manganese ranged from 0.71 mg kg-1 (P6) – 1.65 mg kg-1 (P2), 1.50 mg kg-1 (P2) – 3.38 mg kg-1 (P3), 4.35 mg kg-1 (P1)- 5.62 mg kg-1 (P5) and 5.6 mg kg-1 (P4) to 11.95 mg kg-1 (P6) respectively. A mixed trend is observed across horizons in all profiles. DTPA-Fe exhibited low variability while the other micronutrients displayed higher variability. The DTPA extractable Zn was found to be deficient whereas DTPA extractable Cu and Mn were found to be sufficient. The available Mn was decreased with increasing depth in most of the profiles. All the micronutrient are positive correlation with organic carbon content.

Aims: To study the optimization and characterization of chitosan-based edible films for food packaging applications
Study Design: This study was experimental and conducted in a lab.
Place and Duration of Study: The study was conducted at the Department of Dairy Technology, Dairy Science College, Hebbal, Bengaluru, Karnataka, India, between October 2022 and July 2023.
Methodology: The edible film was developed with 9 different combinations by 3 concentrations of chitosan 1.50, 2.0 and 2.5% along with 3 concentrations of glycerol 0.5, 0.75 and 1%. Various characteristics like moisture content, water solubility, thickness, density, GSM, colour, transmittance, water vapor transmission rate (WVTR), tensile strength, elongation are assessed. The film was optimised on the basis of water vapor transmission rate, tensile strength and elongation. ANOVA was the method used for statistical analysis, and the significance between the control and sample was assessed using a critical difference (CD) at a 5% significance level.
Results: Increase in chitosan concentration the film thickness, GSM, solubility and density increases whereas moisture content decreases. Increase in glycerol concentration the film thickness, GSM, moisture, solubility increases but there was decrease in film density. The film colour parameters lightness L*, redness a* and yellowness b* increase as chitosan content increases, whereas transmittance decreases. Increased glycerol content increased the film's colour parameters redness a* and transmittance, but had no influence on the film's yellowness whereas as the lightness value decreases. The film made with 2.5% chitosan and 0.5% glycerol has the lowest water vapour transmission rate, 10.70 g/m2h. The tensile strength of film made with 2.5% chitosan and 0.5% glycerol has the highest value of 18.56 MPa. Film produced using 1.5% chitosan and 1% glycerol has the highest value of 51.73% elongation.
Conclusion: Increasing the concentration of chitosan improves tensile strength but reduces elongation. On the other hand, adding more glycerol lowers tensile strength but increases elongation. A film containing 2% chitosan and 0.75% glycerol is considered the best choice, offering a balanced water vapor transfer rate, tensile strength, and elongation.

AbstractDumbbell‐shaped systems based on PAHs‐BODIPY‐triarylamine hybrids TM‐(01‐04) are designed as novel and highly efficient hole‐transporting materials for usage in planar inverted perovskite solar cells. BODIPY is employed as a bridge between the PAH units, and the effects of the conjugated π‐system's covalent attachment and size are investigated. Fluorescence quenching, 3D fluorescence heat maps, and theoretical studies support energy transfer within the moieties. The systems are extremely resistant to UVC 254 nm germicidal light sources and present remarkable thermal stability at degradation temperatures exceeding 350 °C. Integrating these systems into perovskite solar cells results in outstanding power conversion efficiency (PCE), with TM‐02‐based devices exhibiting a PCE of 20.26%. The devices base on TM‐01, TM‐03, and TM‐04 achieve PCE values of 16.98%, 17.58%, and 18.80%, respectively. The long‐term stability of these devices is measured for 600 h, with initial efficiency retention between 94% and 86%. The TM‐04‐based device presents noticeable stability of 94%, better than the reference polymer PTAA with 91%. These findings highlight the exciting potential of dumbbell‐shaped systems based on PAHs‐BODIPY‐triarylamine derivatives for next‐generation photovoltaics.

AbstractEnallenylamides have been utilized for the synthesis of heterobicycle[4.2.0]octane derivatives via Ir/hν promoted [2+2] cycloaddition reaction. The reaction specifically targets the distal double bond of the allene moiety, and results in the exclusive formation of the trans product. The process is conducted at room temperature and under an inert atmosphere. An extensive study on the substituent propensities during the cycloaddition step revealed variable effects. Electron‐withdrawing groups conjugated with the double bond participating in the cycloaddition either hindered the process or reduced its yield. Conversely, electron‐donating substituents enhanced the efficiency, resulting in product yields ranging from 60% to 88%. Our study also demonstrated the influence of protecting groups on the reaction pathway.

Published: July 2023

AbstractOver the last decade, the rapid development of wearable electronics has generated renewed interest in textiles. The integration of advanced nanotechnology and microelectronics with well‐established textile production processes has resulted in textile electronics, that are lightweight, flexible, breathable, and conformable, which broadens the applications of electronic products. The hierarchical textile structure, ranging from a single fiber to twisted yarns and various fabrics, is suitable for constructing multifunctional flexible devices. In particular, yarn, which bridges between fiber and fabric, is advantageous owing to its easy integration into wearable formats via weaving, knitting, or braiding. However, because of the dearth of effective interdisciplinary communication between researchers of electronic and textile engineering, fabricating yarn‐based devices with superior mechanical properties and versatile electronic functionality is difficult. Therefore, this review provides an overview of yarn‐based electronics, followed by a systematical summary of recent progress in yarns with respect to material and device design, multifunctional integration, and applications in wearable devices, including sensors, actuators, stealth, batteries, and nanogenerators. Furthermore, the major challenges and future developments in this field are discussed.

AbstractWe report the surface modification of ferrite nanoparticles (MFe2O4 NPs; M= Mn, Fe, Co, Ni, Cu, Zn) with chiral surfactants derived from cinchona alkaloids. The successful synthesis of chiral ferrites were characterized using powder X‐ray diffraction (PXRD), X‐ray photoelectron spectroscopy (XPS), Atomic force microscopy (AFM), Thermogravimetric analysis (TGA) and vibrating sample magnetometer (VSM). These chiral materials were highly active in the oxidative kinetic resolution (OKR) of racemic benzoins. Remarkably gemini surfactant modified Fe3O4 NPs were found to be a potential candidate in the OKR and (R)‐benzoin was isolated with 97% enantiomeric excess (ee). The sustainability of our catalyst has been demonstrated in the gram scale synthesis of (R)‐furoin (93% ee). The recyclability studies have also been performed and found that it could be recyclable with decrease in ee.

AbstractSolvothermal reaction of 5,5′‐(pyridine‐2,6‐diylbis(oxy))diisophthalic acid (H4L) with europium(III) or terbium(III) nitrates in acetonitrile‐water (1 : 1) at 120 °C gave rise to isostructural 2D coordination polymers, [Ln(HL)(H2O)3]∞ (NIIC‐1‐Eu and NIIC‐1‐Tb), the layers of which are composed by eight‐coordinated lanthanide(III) ions interconnected by triply deprotonated ligands HL3−. The layers are packed in the crystal without any specific intermolecular interactions between them, allowing the facile preparation of stable water suspensions, in which NIIC‐1‐Tb exhibited top‐performing sensing properties through luminescence quenching effect with exceptionally low detection limits towards Fe3+ (LOD 8.62 nM), ofloxacin (OFX) antibiotic (LOD 3.91 nM) and cotton phytotoxicant gossypol (LOD 2.27 nM). In addition to low detection limit and high selectivity, NIIC‐1‐Tb features fast sensing response (within 60–90 seconds), making it superior to other MOF‐based sensors for metal cations and organic toxicants. The photoluminescence quantum yield of NIIC‐1‐Tb was 93 %, one of the highest among lanthanide MOFs. Mixed‐metal coordination polymers NIIC‐1‐EuxTb1−x demonstrated efficient photoluminescence, the color of which could be modulated by the excitation wavelength and time delay for emission monitoring (within 1 millisecond). Furthermore, an original 2D QR‐coding scheme was designed for anti‐counterfeiting labeling of goods based on unique and tunable emission spectra of NIIC‐1‐Ln coordination polymers.

Published: July 2023

AbstractAlthough many monometallic active sites have been installed in metal–organic frameworks (MOFs) for catalytic reactions, there are no effective strategies to generate bimetallic catalysts in MOFs. Here we report the synthesis of a robust, efficient, and reusable MOF catalyst, MOF‐NiH, by adaptively generating and stabilizing dinickel active sites using the bipyridine groups in MOF‐253 with the formula of Al(OH)(2,2′‐bipyridine‐5,5′‐dicarboxylate) forZ‐selective semihydrogenation of alkynes and selective hydrogenation of C=C bonds in α,β‐unsaturated aldehydes and ketones. Spectroscopic studies established the dinickel complex (bpy⋅−)NiII(μ2‐H)2NiII(bpy⋅−) as the active catalyst. MOF‐NiH efficiently catalyzed selective hydrogenation reactions with turnover numbers of up to 192 and could be used in five cycles of hydrogenation reactions without catalyst leaching or significant decrease of catalytic activities. The present work uncovers a synthetic strategy toward solution‐inaccessible Earth‐abundant bimetallic MOF catalysts for sustainable catalysis.

Published: July 2023

AbstractLuminescent thermometry allows the remote detection of the temperature and holds great potential in future technological applications in which conventional systems could not operate. Complementary approaches to measuring the temperature aiming to enhance the thermal sensitivity would however represent a decisive step forward. For the first time, we demonstrate the proof‐of‐concept that luminescence thermometry could be associated with a complementary temperature readout related to a different property. Namely, we propose to take advantage of the temperature dependence of both magnetic (canonical susceptibility and relaxation time) and luminescence features (emission intensity) found in Single‐Molecule Magnets (SMM) to develop original dual magneto‐optical molecular thermometers to conciliate high‐performance SMM and Boltzmann‐type luminescence thermometry. We highlight this integrative approach to concurrent luminescent and magnetic thermometry using an air‐stable benchmark SMM [Dy(bbpen)Cl] (H2bbpen=N,N′‐bis(2‐hydroxybenzyl)‐N,N′‐bis(2‐methylpyridyl)ethyl‐enediamine)) exhibiting Dy3+ luminescence. The synergy between multiparametric magneto‐optical readouts and multiple linear regression makes possible a 10‐fold improvement in the relative thermal sensitivity of the thermometer over the whole temperature range, compared with the values obtained with the single optical or magnetic devices.
Supramolecular Enhancement of Electrochemical Nitrate Reduction Catalyzed by Cobalt Porphyrin Organic Cages for Ammonia Electrosynthesis in Water**

Published: July 2023

AbstractThe electrochemical nitrate (NO3−) reduction reaction (NO3RR) to ammonia (NH3) represents a sustainable approach for denitrification to balance global nitrogen cycles and an alternative to traditional thermal Haber‐Bosch processes. Here, we present a supramolecular strategy for promoting NH3 production in water from NO3RR by integrating two‐dimensional (2D) molecular cobalt porphyrin (CoTPP) units into a three‐dimensional (3D) porous organic cage architecture. The porphyrin box CoPB‐C8 enhances electrochemical active site exposure, facilitates substrate–catalyst interactions, and improves catalyst stability, leading to turnover numbers and frequencies for NH3 production exceeding 200,000 and 56 s−1, respectively. These values represent a 15‐fold increase in NO3RR activity and 200‐mV improvement in overpotential for the 3D CoPB‐C8 box structure compared to its 2D CoTPP counterpart. Synthetic tuning of peripheral alkyl substituents highlights the importance of supramolecular porosity and cavity size on electrochemical NO3RR activity. These findings establish the incorporation of 2D molecular units into 3D confined space microenvironments as an effective supramolecular design strategy for enhancing electrocatalysis.
Programmable Amine Synthesis via Iterative Boron Homologation

Published: July 2023

AbstractThe value of Matteson‐type reactions has been increasingly recognized for developing automated organic synthesis. However, the typical Matteson reactions almost exclusively focus on homologation of carbon units. Here, we report the detailed development of sequential insertion of nitrogen and carbon atoms into boronate C−B bonds, which provides a modular and iterative approach to access functionalized tertiary amines. A new class of nitrenoid reagents is uncovered to allow direct formation of aminoboranes from aryl or alkyl boronates via N‐insertion. The one‐pot N‐insertion followed by controlled mono‐ or double‐carbenoid insertion has been realized with widely available aryl boronates. The resulting aminoalkyl boronate products can undergo further homologation and various other transformations. Preliminary success on homologation of N,N‐dialkylaminoboranes and sequential N‐ and C‐insertions with alkyl boronates have also been achieved. To broaden the synthetic utility, selective removal of a benzyl or aryl substituent permits access to secondary or primary amine products. The application of this method has been demonstrated in the modular synthesis of bioactive compounds and the programmable construction of diamines and aminoethers. A plausible reaction mechanism, supported by preliminary NMR (nuclear magnetic resonance) and computational studies, is also proposed.
