Authors: Ünal Filiz , Eğerci Yeşim , Kurbetli İlker
Published: March 2024

Bu çalışma, Rhizoctonia solani AG 4'e karşı etkili fungisitlerin ve bunların farklı dozlarının aktivatörlerle kombinasyonunun sonuçlarını tespit etmek ve düşük dozda fungisit kullanımı ile çevre dostu bir mücadele yöntemi tespit etmek amacıyla yapılmıştır. İn vitro koşullarında fungusa karşı etkili bulunan iki fungisitin farklı dozlarının Lactobacillus acidophilus, Arthrobacter sp. ve Harpin Protein ile kombinasyonlarının etkisi öncelikle sera koşullarında saksı denemeleri ile belirlenmiştir. Antalya ve Ankara’da arazi koşullarında ise saksı denemelerinde başarılı bulunan iki kombinasyonun hastalığa karşı etkileri araştırılmıştır. Tarla koşullarındaki deneme sonuçlarına göre % 90.77 ile en yüksek etki Arthrobacter sp.-(Prothioconazole+Spiroxamine) önerilen doz (100 mL da-1) kombinasyonunda bulunurken bunu fungisit dozunun azaltıldığı % 88.37 etki ile Arthrobacter sp.-(Prothioconazole+Spiroxamine) (50 mL da-1) takip etmiştir. Hastalığa karşı tek başına kullanılan Arthrobacter sp., Lactobacillus acidophilus, ve Harpin Protein sırasıyla % 46.20, % 39.73 ve % 23.40 düşük etki değerleri ile sonlarda yer almıştır. Sonuç olarak düşük doz fungisit kullanılmasından dolayı çevre dostu bir mücadele uygulaması olarak Arthrobacter sp.-(Prothioconazole+Spiroxamine) 1. alt doz (50 mL da-1) uygulamasının, çim alanlarında Rhizoctonia solani AG 4 mücadelesi için etkili olabileceği sonucuna varılmıştır.

Published: March 2024

İris (Iris spp.) bitkilerinde uzun yıllar boyunca yapraklarda şiddetli mozaik, sararma ve nekroz gibi belirtiler gözlemlenmiştir. Bu çalışma kapsamında iris bitkilerinde ilgili simptomlara neden olabilecek Potyvirüs türlerinin varlığı araştırılmıştır. Arazi çalışmaları 2022 yılında Güney Marmara Bölgesi’nde bulunan Bilecik ilinde gerçekleştirilmiştir. Çalışmada, 34 simptomatik ve 7 asimptomatik olmak üzere toplam 41 iris bitkisi toplanmıştır. Potyvirüs enfeksiyonları, Potyvirüs cinsine özgün kısmi NIb (nuclear inclusion protein b) gen bölgesinin amplifikasyonuna yönelik dejenere primerler kullanarak konvansiyonel moleküler yöntemler ile belirlenmiştir. Moleküler çalışmalar sonucunda virüslerin neden olduğu belirtiler gösteren 6 bitkide Potyvirüs enfeksiyonu tespit edilmiştir. Elde edilen 6 Potyvirüs fragmentinin nükleotit dizileme çalışmaları tamamlandıktan sonra enfeksiyonlara iris şiddetli mozaik virüsü (iris severe mosaic virus, ISMV)’nün neden olduğu belirlenmiştir. Bu izolatlar kendi aralarında % 94’ün üzerinde nükleotit benzerliği gösterirken, global izolat ile % 82-99 oranlarında benzerlik göstermiştir. Filogenetik analizler ise bu dejenere primerle elde edilen NIb gen bölgesine göre Potyvirüs türlerinin kendi aralarında başarılı bir şekilde ayrıldığını göstermiştir.
Effects of Selenium on DNA Methylation and Genomic Instability Induced by Drought Stress in Wheat (Triticum aestivum L.)
Authors: Şahin Zehra , Ağar Güleray , Yiğider Esma , Aydın Murat
Published: March 2024

The main purpose of the study was to clarify the effect of selenium (Se) on DNA damage and DNA methylation in wheat (Triticum aestivum L.) plants exposed to polyethylene glycol (PEG)-induced drought stress under in vitro tissue culture. Random amplified polymorphic DNA (RAPD) and coupled restriction enzyme digestion-random amplification (CRED-RA) were utilized to explain the DNA damage grade and variations in DNA methylation patterns, respectively. The outcomes indicate that drought stress gives rise to a rise in RAPD profile variations (as DNA damage) and a decrease in genomic template stability (GTS) rate and DNA methylation changes. According to the RAPD data, the greatest GTS value was computed at 56.9% (5% PEG 6000), and the lowest GTS value was 41.2% (15% PEG 6000), demonstrating the adverse effects of PEG 6000. However, DNA damage can be reduced by treatment with sodium selenate (2, 4, and 6 µM of Na2SeO4) together with PEG (5%, 10%, and 15% PEG 6000)-induced water deficits. Moreover, according to CRED-RA analysis, PEG-induced DNA methylation rates were changed after treating different doses of Se. These data demonstrate that Se dose-dependently modulates both DNA damage and methylation alterations induced by drought in wheat.
Commodity Exchanges in Structure of Energy Market: a Fresh Look
Authors: Telegina E. , Cherniy B.
Published: March 2024

The paper offers a systematized and updated view of exchange-traded energy products. The increase in natural gas and electricity trade volumes at commodity exchanges has dramatically changed the wholesale market structure in Europe. Nowadays commodity exchanges have played an essential role in energy trading. The complexity of exchange technologies and the reasons for their demand are often hidden under everyday exchange routine. Academic analysis of exchange activity has traditionally been feebly developed, because, firstly, classical economics assumes that finding of equilibrium between supply and demand is an instantaneous and cost-free process. Markets were mainly described as simple market exchanges where faceless buyers and sellers meet for an instant to exchange standardized goods at equilibrium prices. Secondly, energy exchanges are relatively new phenomenon. The justification of exchange trading became possible as a result of new institutional economics (NIE) and transaction cost theory (TCT) findings. Under conditions of positive transaction costs, incomplete foresight and bounded rationality – the conditions of the New Institutional Economics (NIE) – the institutional framework not only of firms but also of markets matters. Also, within this institutional framework the concept of “governance structure” was introduced. A high-performance system shall align transactions with governance structures in relation to their adaptive needs. Governance structures are properly regarded as part of the optimization problem. A shift from one structure to another may permit a simultaneous reduction in both the expense of writing a complex contract and the expense of executing it effectively in an adaptive, sequential way. The founders of NIE and TCT, having been investigating the stock and commodity exchanges, approached them as a measure of transaction costs for other-the-counter trades. However, they did not include exchange trading into classification of governance structures. As far as is known, it has not been described in this way in terms of NIE and TCT to date. Natural gas and electricity markets is a good examples of network industries, which are an appropriate case of institutional flexibility regarding the alignment between transactions and governance structures. “Liberalised” network industries needed and still need an “intense” design and re-design to be able to host any kind of markets and to interact with. Organized markets, energy exchanges have developed a required bridge between leaving long-term contracts and price promulgation. The hypothesis of energy exchange classification as a special type of governance structure, in the meaning of NIE and TCT, for network industries is discussed in this article.

Published: March 2024

Abstract: Exercise has been repeatedly shown to be safe and beneficial for cancer survivors. However, there is no normative guideline for exercise prescription, and it is under exploration. Therefore, this literature review aims to provide some advice for the formulation of exercise prescriptions for patients with breast cancer-related lymphedema (BCRL) from the perspective of reducing lymphedema severity. A review of relevant studies published before November 2023 was conducted using three scientific databases PubMed, Embase, and Scopus. A total of 2696 articles were found. Eventually, 13 studies fulfilled the inclusion criteria and were included in this literature review. We concluded daily, or nearly daily exercise at home can be recommended. Moreover, reduced lymphedema severity may not be maintained after ceasing the exercise program, so exercise should be a lifelong practice.

Authors: Knitter-Piątkowska Anna , Przychodzki Maciej , Guminiak Michał
Published: March 2024

The paper delves into the critical issue of damage detection within the guy cable of a truss steel mast, a pivotal component in structural integrity. It introduces a model wherein damage manifests as a localized cross-section reduction in a single element of the cable. Employing Discrete Wavelet Transform (DWT), a pioneering methodology, the study scrutinizes the behavior of the affected elements through static structural analyses. Signal decomposition via the Mallat pyramid algorithm facilitates comprehensive examination. Static displacements at the connection point between the cable and the truss mast serve as the measured variables. Through systematic investigation, the paper evaluates the impact of damage size and location, external loading force, and cable tension force on the efficacy of the proposed approach. Utilizing data derived from Finite Element Method (FEM) computations for wavelet analysis the authors substantiate the findings with numerical examples, thus offering valuable insights into damage detection strategies for structural health monitoring and engineering applications.

Published: March 2024

This study delves into the critical domain of public procurement, specifically focusing on Sustainable Public Procurement (SPP) and Environmental, Social, and Governance (ESG) considerations within the context of South Korea. The aim of this research is to empirically scrutinize the factors influencing the impact index of SPP, with a particular emphasis on services related to labor standards. The investigation spans three years, from January 1, 2019, to July 31, 2021, encompassing state agency orders and post-implementation legal changes. Leveraging the comprehensive Korea On-line E-Procurement Sys-tem(KONEPS) platform, we meticulously collected data, ultimately culminating in 21,573 services meeting our criteria, from which 250 cases underwent an in-depth analysis. The study sheds light on the influence of social responsibility evaluation cri-teria on overall procurement scores, while also uncovering the moderating effects of various factors.
The outcomes of this study offer valuable insights into the impact index of social responsibility evaluation criteria within South Korea's public procurement landscape. Factors including procurement year, classification, service period, and estimated price were identified as significant influencers. Moreover, the number and location of evalu-ation criteria items, inclusion of sincerity elements, and the evaluating agency were deemed pivotal determinants of the influence index. These findings hold profound implications for policymakers, procurement practitioners, and researchers and provide a roadmap for optimizing the utilization of social responsibility evaluation criteria to advance responsible and sustainable procurement practices.
Future research avenues include conducting further study of additional moderat-ing variables, expanding datasets to encompass a broader spectrum of procurement contexts, and evaluating the long-term repercussions of social responsibility evaluation on procurement outcomes. These endeavors promise to further refine and advance public procurement practices in South Korea and beyond.

Antibiotic resistance is one of the main challenges faced by the health world today. Therefore, various efforts are being made to find new alternative antibiotics from various sources. Endophytic bacteria from medicinal plants are thought to have an antibacterial activity that can potentially inhibit pathogenic bacteria growth. This study aimed to isolate and characterize endophytic bacteria from the Dayak onion plant and determine their potential to inhibit the growth of two pathogenic bacteria Escherichia coli and Staphylococcus aureus. Bacterial isolation was carried out using the surface sterilization method and grown on nutrient agar media. The endophytic bacteria isolates obtained were then characterized macroscopically and microscopically. The agar plug diffusion method carried out the antagonism test against pathogenic bacteria. The result showed that 40 isolates of endophytic bacteria were successfully isolated from the Dayak onion plant's leaves, bulbs, and roots. Based on the antagonism test, 3 isolates were able to inhibit E.coli while 8 isolates were able to inhibit S. aureus. Three isolates (CED3, CED4, and CEU6) were able to inhibit both pathogenic bacteria, and the highest activity was shown by CED3 isolates.

Religious moderation is politically included in public policies that are integrated into the 2020-2024 National Medium-Term Development Plan (Rencana Pembangunan Jangka Menengah Nasional, RPJMN). Ministry of Religion as the leading sector for mainstreaming religious moderation in its environment has the responsibility to translate religious moderation from the narrative of religious moderation to the real action in its institutional units. This research is qualitative research conducted at State Islamic University (Universitas Islam Negeri, UIN) Walisongo Semarang which seriously promotes religious moderation in the institution. The results of this study are the problem of strengthening identity politics as one of the main causes of religious extremism and social change that exist, one of the efforts to minimize social turmoil in UIN Walisongo is by instilling the values of religious moderation through the tri dharma of university, namely teaching, research, and community service. The aspect of locality is the main capital in implementing religious moderation at UIN Walisongo. Indigenous religiosity combines religion and locality with a theo-anthropocentric approach, exploring cultural values in order to strengthen religion in the implementation aspect. The impact of the implementation of the data religious moderation policy is seen from the realm of ideality of policy content in the religious moderation policy, which can be seen from the integration of relations or a harmonious relationship between individual elements and social elements in human interaction which is the main target in the religious moderation policy promoted by the Ministry of Religion.
Formation of the Great Bend and Enhanced Quaternary Incision of the Upper Yangtze River: New Insights from Low-Temperature Thermochronology and Tributary Morphology
Authors: Zheng Yong , Pan Jiawei , Li Haibing , Wang Yang , Gong Zheng , Bai Mingkun
Published: March 2024

The occurrence of a sharp turn along the upper course of the Yangtze River is referred to as the “Great Bend” and represents a large-scale drainage reorganization in response to the surface rise of the Tibetan Plateau. However, the timing and mechanism of the formation of the Great Bend remain disputed. In this paper, we report new (U–Th)/He and apatite fission track thermochronological data from the deep river valley in the Great Bend area of the southeastern margin of the Tibetan Plateau. Compared with the adjacent Jianchuan Basin, two phases of younger rapid cooling for the Great Bend area are identified based on thermal-history modeling, namely, Miocene (ca. 17 to 11–8 Ma) and Quaternary, with the former phase being contemporaneous with the formation of the anticline in the Tiger Leaping Gorge. Progressive increases in the normalized channel steepness (ksn) and the degree of river-valley incision with increasing distance downstream for tributaries of the Yangtze River in the Tiger Leaping Gorge indicate that river rerouting and formation of the Great Bend occurred during the Miocene. Samples located at the bottom of the Tiger Leaping Gorge also reveal a phase of rapid cooling since ca. 1.9 Ma, with an exhumation rate of 1.5 ± 0.2 mm/year. We hypothesize that enhanced Quaternary exhumation in the southeastern margin of the Tibetan Plateau occurred mainly within the narrow region between the Sichuan Basin and the Eastern Himalayan Syntaxis, corresponding to an episode of widespread extensional deformation superimposed above middle- to upper-crustal flexure in this region.
Experimental Investigation on the Grouting Performance of Foam-CNT Composite Grouts in Vertical Inclined Fractures Under Flowing Condition
Authors: Liu Yaohui , Lv Fang , Ouyang Zebin , Wang Tao
Published: March 2024

Grouting is an effective method to solve the problem of water inrush in tunnel and underground engineering. However, rock fractures are often simplified as horizontal and smooth fractures in most grouting studies, while studies on vertical inclined fractures are still rare. To investigate the diffusion law in vertical inclined fractures, a vertical inclined fracture grouting simulation device was developed. A new type of cement slurry with low weight and high flowing water resistance was developed by combining carbon nanotube (CNT) slurry with foamed cement. Physical simulation experiments were conducted to investigate various factors (initial flowing water, inclination angle, sand content, and grouting rate) on the sealing efficiency of grouting. Results show that the high foam content has a negative effect on the compressive strength of the slurry, and has a positive effect on the fluidity and water resistance. The optimum ratio of slurry is 30% foam content, 1.0% CNT content, 1.3 water/cement ratio, and 3% additive content. The inclination angle and inclination direction of the fracture have a great influence on the sealing efficiency of grouting. Foam-CNT composite grouts can meet the requirement of flowing water grouting in vertical inclined fractures.
Effects of Clay Contamination on the Stability of Aqueous Foams at High Pressure
Authors: Obisesan Oyindamola , Ahmed Ramadan , Ahmed Nayem , Amani Mahmood
Published: March 2024

Because of its low density, high viscosity, and good hole-cleaning performance, foam is used in the industry as a drilling and completion fluid. Due to these unique properties, foam can be applied in underbalanced drilling. After an extended period, however, the degradation of its thermodynamically unstable structure leads to the gradual loss of these valuable properties. While a number of research studies have been performed to investigate foam flow behavior, more is needed to know about their drainage characteristics and stability at high pressure.

The primary goal of this investigation is to examine the effects of clay contaminants on the drainage of foam at high pressure. Moreover, the results and findings of this study not only show the effect of clay contaminants on foam stability but also help develop clay-based stable foam formulations without using chemicals that have the potential to contaminate groundwater or seawater.

This paper shows the findings of an investigation on the aqueous foam stability in the presence of clay (bentonite and kaolinite) contaminants. Experiments were conducted at ambient temperature while varying foam quality and clay concentration at a constant pressure of 6.8 MPa. During the study, the foam was created in a flow loop. After generation, its rheology and stability were measured using a pipe viscometer and a vertical test tube (column). The hydrostatic pressure profile in the column was measured with time to assess foam drainage.

The results show that clay type and concentration affect aqueous foam drainage and flow behavior. The impact of clay on these foam properties is controlled by foam quality. Adding more than 2.5% bentonite considerably enhanced foam stability and viscosity. In contrast, the impacts of kaolinite on these foam properties were minimal at the same concentration. The drainage became negligible when 5% bentonite was added to the foam. However, at a reduced concentration (2.5%), bentonite addition was only an effective stabilizer for low-quality foam (40%). Microscopic examination of the foams prepared under ambient conditions demonstrated the accumulation of colloidal particles at the plateau borders and nodes that block the drained liquid flow and reduce drainage.
Experimental Study of the Effect of Molecular Collision Frequency and Adsorption Capacity on Gas Seepage Flux in Coal
Authors: Gao Yang , Yu Qingchun
Published: March 2024

The differences in the transport behavior and adsorption capacity of different gases in coal play crucial roles in the evolution of coal permeability. Previous studies of coreflooding experiments failed to explain the mechanism of gas flow and have attributed the variation in gas seepage flux (flow rate) at the beginning of the experiment to the change in effective stress, while the differences in the microscopic properties of different gases, such as molar mass, molecular diameter, mean molecular free path, and molecular collision frequency, were ignored. To research the effect of these gas properties on seepage flux while circumventing the effective stress, coreflooding experiments with helium (He), argon (Ar), nitrogen (N2), methane (CH4), and carbon dioxide (CO2) were designed. The results show that the gas transport velocity in coal is affected by the combination of molecular collision frequency and dynamic viscosity, and the transport velocities follow the order of ν (CH4) > ν (He) > ν (N2) > ν (CO2) > ν (Ar). A permeability equation corrected by the molecular collision frequency is proposed to eliminate differences in the permeabilities measured with different gases. The adsorption of different gases on the coal matrix causes different degrees of swelling, and the adsorption-induced swelling strains follow the order of ε (CO2) > ε (CH4) > ε (N2) > ε (Ar) > ε (He). The reduction in seepage flux and irreversible alterations in pore structure caused by adsorption-induced swelling are positively correlated with their adsorption capacities. The gas seepage fluxes after adsorption equilibrium of coal follow the order of Q (He) > Q (CH4) >Q (N2) > Q (Ar) > Q (CO2). Like supercritical CO2 (ScCO2), conventional CO2 can also dissolve the organic matter in coal. The organic molecules close to the walls of the cleats along the direction of gas flow are preferentially dissolved by CO2, and the gas seepage flux increases when the dissolution effect on the cleat width is greater than that on adsorption swelling.

This research significantly advances Component-Wise Natural Gradient Descent (CW-NGD), a network training method that facilitates efficient parameter updates by approximating the curvature Fisher Information Matrix. By the investigation of the exponential moving average integration, and appropriate hyperparameters selection obtained from the comprehensive analysis results, significant enhancements in CW-NGD's performance have been achieved. Particularly we enhance CW-NGD to operate across multiple GPUs, bypassing the memory constraints when working with large-scale models. These improvements enable CW-NGD to attain state-of-the-art accuracy on deep networks, which prior work could not achieve In an expansive comparison across four diverse datasets and models, CW-NGD achieves similar or superior accuracy while outperforming all other established network training methods, encompassing Adam, Stochastic Gradient Descent, and Kronecker-factored Approximate Curvature, in terms of convergence speed and stability. This study establishes CW-NGD as a robust and versatile network training technique, showcasing its adaptability and potential applications across various domains.

The Chinese cabbage (Brassica rapa L.ssp. pekinensis) is suffering more and more serious blackleg disease, leading to a great impact on cultivation and development of the vegetable species in recent years. To make deep insight of the blackleg disease, the relevant characteristics of its causal pathogen was studied in this work. Upon morphology observation and specific PCR amplification, the blackleg causal pathogen was considered as Leptosphaeria biglobosa ‘brassicae’ B3.5 (Lbb B3.5), a weakly progressive pathogen on Brassicae napus, which could produce disease lesions on cotyledons and true leaves of Chinese cabbage seedlings. Under pathogenicity test, the pathogen was not easy to invade into the interior tissue of true leaves of resistant materials, not generating disease spots until on the 12th day after inoculation. Yet the pathogen mycelium tissue was soon observed in true leaves of susceptible materials only on the 2nd day after inoculation, then resulting in the visible disease spots on the 4th day after inoculation. Through the measurement of (superoxide dismutase (SOD) activity, phenylalanine ammonia lyase (PAL) activity, chitinase activity and malondialdehyde (MDA) content, except for the MDA content, the activity of three kinds of defense enzymes in resistant treatments were higher than that in susceptible treatments. In addition, two effector protein encoding genes (Avrlm3, Avrlm4-7) were detected in the blackleg causal pathogen of Chinese cabbage. The blackleg causal pathogen of Chinese cabbage belongs to a kind of weak Leptosphaeria subspecies, with stronger pathogenicity on Chinese cabbage. The pathogen could influence the defense enzyme activity of resistant and susceptible materials and contain homologous effector protein encoding genes of progressive Leptosphaeria subspecies.
Fracture toughness of mixed-mode anticracks in highly porous materials

Published: March 2024

When porous materials are subjected to compressive loads, localized failure chains, commonly termed as anticracks, can occur and cause large-scale structural failure. Similar to tensile and shear cracks, the resistance to anticrack growth is governed by fracture toughness. Yet, nothing is known about the mixed-mode fracture toughness for highly porous materials subjected to shear and compression. We present novel fracture mechanical field experiments tailored for weak layers in a natural snowpack. Using a mechanical model for interpretation, we calculate the fracture toughness for anticrack growth for the full range of mode interactions, from pure shear to pure collapse. The measurements show that fracture toughness values are significantly larger in shear than in collapse, and suggest a power-law interaction between the anticrack propagation
modes. Our results reveal new insights into the fracture characteristics of anticracks in highly porous materials and provide important benchmarks for computational modeling.

Published: March 2024

The bound states in the continuum (BICs), coupled resonance in non-Hermitian system, is typically manifested by a zero linewidth and an infinite resonance quality factor. These unique features facilitate various developments and applications in low-threshold lasers, ultrasensitive sensing, and highly efficient optoelectronics. Numerous research has been devoted to achieving perfect absorption leveraging BICs in the visible regime. For hybrid systems, it is a major issue to manipulate BICs in the ultraviolet regime. Moreover, there is currently a lack of achieving perfect absorption leveraging BICs in the ultraviolet regime. Here, a kind of Al/SiO2 hybrid system is theoretically proposed to realize perfect absorption by motivating various types of BICs in the ultraviolet regime. In this work, the perfect absorption of 99.97% can be achieved in the Al/SiO2 hybrid system at the wavelength of 304.4 nm. Importantly, the BICs can be modulated into the ultraviolet regime by adjusting the geometric parameters and the incident light angles, and the Q factor of 1099.4 can be successfully obtained. This work builds a theoretical foundation to realize the perfect absorption leveraging BICs for UV light detection.

Published: March 2024

Autophagy is a highly conserved eukaryotic pathway and plays a crucial role in cell survival under stress. Here, we applied a full-length transcriptome approach to study Arabidopsis autophagy mutant (atg5-1) exposed to nitrogen-starvation, using Oxford Nanopore Technologies. A total of 39,033 transcripts were identified, including 11,356 new transcripts. In addition, alternative splicing (AS) events and lncRNAs were also detected between Col-0 (WT) and atg5-1. Differentially expressed transcripts enrichment shown that autophagy upregulates the expression of many stress-responsive genes and inhibits transcription of photosynthesis-associated genes. The results of qRT-PCR showed that the expression patterns of photosynthesis-related genes in the atg5-1 were different under the conditions of nitrogen starvation and carbon starvation. Under nitrogen starvation treatment, many genes related to photosynthesis also exhibited AS. The chlorophyll fluorescence images showed that the Fv/Fm and ΦPSII of old atg5-1 leaves were significantly reduced after nitrogen starvation treatment, but the Y(NPQ) indices were significantly increased compared to those of WT. Taken together, the results provide new insights into how new transcripts, lncRNAs and AS (alternative splicing) are involved in plant autophagy through full-length transcriptome sequencing and suggest a new potential link between autophagy and photosynthesis.

Published: March 2024

Neutron detectors play a crucial role in fundamental science, nuclear security, safeguards, and civil applications. Traditionally, 3He-filled gas proportional counters are the gold standard for thermal neutron detection, prized for their efficiency, neutron/gamma discrimination, and stability—however, the scarcity of 3He has prompted the search for alternatives. Here, we introduce an innovative neutron detector design based on a scintillating composite consisting of 6Li-enriched glass scintillator particles dispersed in an organic matrix. A detector consisting of this scintillating composite, photomultiplier tubes (PMTs) for optical detection, and electronics for reading out the PMT signal in both pulse and current modes was prototyped and characterized using various neutron and gamma sources. The prototype (69.7 mm diameter and 260 mm length) achieves a detection efficiency of 6.7%, a die-away time of 10.5 µs, a negligible gamma misidentification probability (for 137Cs and 60Co gamma sources), and response linearity up to at least 3.7×106 incident neutrons/s established via an innovative cross-calibration technique. This novel detector holds the potential to outperform traditional 3He-gas-based neutron systems, offering a viable alternative amidst the ongoing 3He shortage and promising advancements in neutron detection technology.
