Synthesis And Photocatalytic Efficiency Under Visible Light Of Biobr-Based Composites
Authors:   , Prasitthikun Tuangphorn
Published: November 2023

This research aimed to improve the photocatalytic activity under visible light of BiOBr-based composites. Due to its narrow band gap energy which can be responded to visible light and good performance for decomposition of harmful organic contaminants, BiOBr becomes one of the promising candidate photocatalysts. Anyhow, the easy recombination of generated electron and hole limited its photocatalytic efficiency. To solve this problem, BiOBr hybriding with other materials such as graphene oxide (GO), reduced-graphene oxide (rGO) and graphitic carbon nitride (g-C3N4) that can enhance charge carriers separation was proposed. From this study, it was found that the enhanced photocatalytic activity of BiOBr was successfully achieved by hybriding with GO, rGO and g-C3N4. The amount of these 3 materials in the composites had played an important role on their photocatalytic efficiency. The highest photocatalytic degradation of Rh-B and nitrogen oxide gas was obtained from BiOBr/ g-C3N4 with 2wt%, which was higher than that of other composites and pure BiOBr. Moreover, these BiOBr-based composites showed high photocatalytic stability after 3 cycles reusing for Rh-B and NOx degradation, in that the BiOBr/ g-C3N4 with 2wt% exhibited the highest reused stability followed by BiOBr/rGO, BiOBr/GO and BiOBr, respectively. As the results, it can be proposed that the BiOBr-based composites synthesized in this study would be promising visible-light responsive photocatalyst materials for water and air purifications in future.
PERFORMANCE ENHANCEMENT OF A FLEXIBLE PRINTED ZINC–AIR BATTERY BY IMPROVING ELECTROLYTE SYSTEM
Authors:   , Chotipanich Jutamart
Published: November 2023

Flexible printed zinc-air battery is an energy storage technology which has the high energy density. However, the difference between theoretical and practical energy densities is quite high. Therefore, in this study, zinc utilization in flexible printed zinc-air battery was enhanced by adding anionic surfactants in 7 mol L-1 KOH which is a traditional electrolyte. These surfactants which are employed consisted of sodium dodecyl benzene sulphonate (SDBS) and sodium dodecyl sulfate (SDS). In addition, an ethanol was also used to improve SDBS and SDS capabilities. Then the battery cells which used various modified electrolytes were examined by the battery analyzer. Additionally, the surface of discharged zinc electrodes was investigated by scanning electron microscope. The results reveal that the capacity and the energy of the batteries are doubled by using SDBS and SDS modified electrolyte. The use of SDS modified electrolyte without ethanol is higher capacity and energy than the use of SDBS additive. The proper concentration for a flexible printed zinc-air battery of both SDBS and SDS is 0.4 mol L-1. Both SDBS and SDS modify the zinc electrode surface to become more porosity, leading to improve the wettability of zinc electrode. Therefore the modified electrolytes can easily penetrate to the zinc electrode, resulting in improvement of active species diffusion. Moreover, addition of ethanol in the modified electrolytes can improve SDBS and SDS capabilities when the surfactant concentration is higher than their critical micelle concentration and the surfactant molecule with the large molecular structure is employed. Furthermore, characteristics of surfactants (such as molecular structure and the CMC) should be taken into account because they also affect the battery performance.
Natural rubber latex – modified asphalts for pavement application
Authors:   , Saowapark Wachira
Published: November 2023

Elastomers are the most utilized modifiers for asphalt products worldwide. In Thailand, natural rubber is currently being used to modify asphalt for pavement throughout the country in order to promote the utilization of this major agricultural product. However, due to limited service life from poor stability of the obtained asphalt mixture, investigation to prolong the stability of the natural rubber-modified asphalt is necessary. This research aims to investigate physical, storage stability, morphology and rheological properties of asphalt using natural rubber (NR), polyphosphoric acid and sulfur as its modifiers. NR is a renewable and ecology friendly elastomer which can use in latex form to avoid severe mixing condition. In this work, small quantity of both PPA and sulfur are proved to be highly effective modifiers working in complementary with the elastomeric system to further enhance stability of the resulting asphalt. The experimental results reveal that when AC 60/70 penetration grade asphalt is modified with 0.6 to 4.5wt% of NR, 1 to 2wt% of PPA and sulfur (based on 100 parts NR) 0.3 to 1.0 wt% using a shear mixer, the penetration of the modified asphalt systematically decreases while its softening points and Brookfield viscosity increase with increasing NR and PPA contents. An addition of sulfur in the asphalt system shows improvement in toughness and tenacity property, as well as storage stability and also promotes compatibility between asphalt and natural rubber. Our results suggest the modified asphalt with 3.2 wt% of NR, 2 wt% of PPA and 0.3 wt% of sulfur (based on 100 parts NR) is a suitable formula to produce asphalt mixture with high stability for pavement application.
POLYMERIZATION OF ETHYLENE WITH BIS[N-(3-TERT-BUTYLSALICYLIDENE)CYCLOHEPTYLAMINE] TITANIUM DICHLORO-SUPPORTED ON SILICA
Authors:   , Thongyoo Pasucha
Published: November 2023

One of the most popular catalysts for ethylene polymerization is metallocene catalyst that is used with methylaluminoxane as cocatalyst because it makes high activity. The metallocene catalysts in a homogeneous system presents very high activity, but major disadvantages of this system are fouling in a reactor and lack of ability to control polymer morphology. Silica is extensively used for heterogeneous system in order to overcome these drawbacks. In the present study, various silica supports are used for supported metallocence catalyst. This research is aimed to study the effect of various amounts of methylaluminoxane with SiO2-LP, SiO2-SP, SiO2-MP, SiO2-VSP and SSP supports for ethylene polymerization via in situ, and to study the effect of SiCl4-modified SiO2-MP support compared with unmodified SiO2-MP support. From the experiment, it was found that the SSP support expressed the highest activity at low methylaluminoxane and the SiO2-LP support showed the highest activity at high methylaluminoxane. The small particles of silica exhibit good activity and big particles show poor reaction on silica surface where high homopolymerization occurred. The polyethylene obtained from modified SiO2-MP support was observed that the crystallinity is higher than the polyethylene obtained from unmodified SiO2-MP support and improved catalytic activity with decreased methylaluminoxane used.
SELECTIVE HYDROGENATION OF 3-NITROSTYRENE TO 3-VINYLANILINE OVER PT-BASED BIMETALLIC CATALYSTS
Authors:   , Tiensermsub Sathaporn
Published: November 2023

The Pt-based bimetallic catalysts on degussa P25 titanium dioxide were synthesized by co-impregnation method with metal from the 4th row of periodic table such as Cr, Fe, Co, Ni, Cu, Zn, and Ga. The catalytic activities were tested in the liquid-phase selective hydrogenation of 3-nitrostyrene (3-NS) to 3-vinylaniline (3-VA) under 2 MPa of H2 and 50ºC. I was found that the 0.5Pt-xFe/TiO2 series exhibited superior NS conversion and higher 3-VA selectivity than the monometallic Pt catalyst. The Pt-Co(0.3-0.5%) and Pt-Ga(0.2-0.5%) also showed improved catalytic performances. The activity of the bimetallic Pt-based catalysts did not follow the CO-chemisorption trend due probably to the Pt-alloy formation and/or the coverage of Pt active site by the 2nd metal. However, the H2-TPR results showed that the reducibility of Pt oxide was easier for the bimetallic catalysts and the XRD results revealed the presence of amorphous phase when Fe, Co, or Ga were added to the Pt catalysts. This could be the reason for higher VA selectivity of these catalysts. The 0.5Pt-0.5Fe/TiO2 showed the best catalytic performances which gave the lowest undesire product (3-ethylnitrobenzene) about 0.2 % with the highest yield of 3-VA at 78%.

Authors:   , Pisuttangkul Suchanut
Published: November 2023

Vanadium phosphorus oxide (VPO) catalysts have been employed in partial oxidation of n-butane and n-pentane. In this study, VPO catalysts were synthesized by refluxing vanadyl phosphate dihydrate (VOPO4•2H2O) with isobutanol and modified with transition metals promoters such as Co, Bi, Fe, and Mn at the mass ratio of M/V 0.35. In the first part, Mn was found to be the best metal to improve the performances of VPO catalyst in n-pentane oxidation. Then the Mn-VPO catalysts were prepared with different ratios of Mn/V loadings at 0.25, 0.35, 0.45, 0.55, and 0.65. All the catalysts were calcined at 300ᵒC for 8 h to generate the vanadyl pyrophosphate ((VO)2P2O7) phase which is the active phase of VPO catalysts and was confirmed by the XRD results. As shown by SEM results, all the synthesized catalysts showed the rosette-shape morphologies of vanadyl pyrophosphate. The transition metal promoted catalysts presented the formation of V4+ state which provided a better catalytic performance with 42.7-55.8% n-pentane conversion, 28.9-62.5% MA selectivity, and 8-13.1% PA selectivity. The optimum ratio of Mn/V was determined to be at 0.45
THE STUDY OF EFFECTS AND MECHANISMS OF INDUSTRIAL CONTROLLED FACTORS ON ELECTROLESS NICKEL IMMERSION GOLD (ENIG) PLATING PROCESS
Authors:   , Pattarakiatikun Suphitsara
Published: November 2023

This research aimed to study the effects of the factors and mechanisms which were controlled by the industry on the electroless nickel immersion gold (ENIG) process including pretreatment step and condition used in ENIG. The thickness analysis of nickel and gold layers by X-ray fluorescence spectrometry (XRF) found that increasing the concentration of precursors, chelating agents, the alkalinity in the controlled range, temperature, and decreasing of oxides on the surface of the substrate resulting in a thick layer of nickel and gold. Also the phosphorus on the nickel substrate caused the thinner layer of gold. For the Ni/P alloy, the nickel composition ratio measured by energy dispersive X-ray spectrometer (EDX) would be greater due to increasing of nickel salt, alkalinity in the EN plating solution or temperature. However, increasing the temperature more than 90 oC caused decomposition of EN plating solution. Moreover, the decreasing of reducing agent resulted in increasing of nickel composition ratio of nickel alloy. The factors affected the roughness and morphology of the nickel surface measured by scanning electron microscopy (SEM) and stylus containing the morphology of the substrate, the gas bubbles generated by the plating reaction which affected the flow of the plating solution and agitation. In the case of gold roughness was based on the nickel surface roughness. The too thick gold plating layer resulted in the dropping of the adhesion between gold layer and nickel surface. The sensitive parameters of EN plating were by-product of plating reaction and pH of EN solution. For IM plating, the sensitive parameter was pH of IM plating solution.

Authors:   , Nimmanterdwong Prathana
Published: November 2023

The recent development of biomass utilization systems to reduce the dependence on non-renewable resources is an effective strategy to achieve a sustainable solution. The evolution of bio-production requires industrial symbiosis strategies called ‘eco-industrial park’ to achieve lower pollution emission and resource consumption. The aim of this study is to provide a sustainability decision tool called emergy accounting analysis using MATLAB language which consists of two components; 1) the search of emergy pathways and 2) the computation of emergy flow. The algorithm has been validated and found to be accurate. Then, the algorithm was applied to a bio-based eco-industrial park model which was developed using ASPEN PLUS. Napier grass (Pennisetum purpureum) grown in Thailand was used as a representative feedstock. The main emergy support the cultivation were human labor resources and diesel consumption. The sustainability indicator (ESI) of the cultivation and the entire system were 0.29 and 0.10, respectively. The reason is that the industrial section relied on imported and non-renewable resources. The integrated biorefinery system with four main products (liquid fuels, methanol, steam and electricity) achieves higher performance in terms of the emergy compared to the existing alternative processes. Finally, emergy and exergy analyses were compared. The exergy analysis provides an insight view mainly on the efficiency of the specific process, while the emergy analysis gives a broader view of the resource supporting to the entire system.

Authors: Adenutsi Deodat Emilson , Whajah Agnes
Published: November 2023

The purpose of this study is three-fold. First, examine the effect of ERM on the operational and financial performances; second, the effect of competitive advantage on operational and financial performances; and third, explore the mediating roles of competitive advantage and financial literacy on the relationship between ERM and the operational and financial performances of SMEs in Ghana. Sampling 8,384 SMEs purposively, the analytical framework was based on SMART PLS-SEM. The empirical results reveal that ERM just as competitive advantage are positive determinants of financial and operational performances of SMEs. Financial literacy does not mediate the relationship between ERM and financial performance, although it partially mediates the relationship between ERM and operational performance just as competitive advantage partially mediates ERM and financial performance. Competitive advantage mediates between ERM and operational performance of SMEs in Ghana. Therefore, effective ERM practices and competitive advantage strategies are necessary conditions for the long-run sustainability of Ghanaian SMEs by way of improved financial and operational performances, given that the key officers are financial literate.

Sustainable development seeks to improve people’s lives and associates economic development and environmental preservation with proper management of natural resources. The objective of this study was to evaluate the sustainability of agroecosystems, based on some sustainability indicators, covering the economic, social and environmental dimensions of rural and rural riverside properties in the southern Amazon region, a predominantly family farming region. The research was based on the SIA - Sustainability Indicators in Agroecosystems, carried out in an interdisciplinary and participative way, and for this purpose, it was necessary to contextualize the bases of the theoretical currents of sustainable development, establishing the historical and current insertion of family agriculture, addressing the attributes of sustainability in the socioeconomic and environmental dimensions. The methodological proposal applied was multivariate statistical analysis, Principal Component Analysis, from the three production systems, in order to identify the similarities underlying all the multiple relationships existing between the indicators, for the construction of the Sustainability Index (SI). Through the use of graphs and tables it was possible to evaluate the production systems in an integrated way and it was verified that the systems are different even though they are inserted in the same region and present a regular sustainability index.

The manuscript demonstrate which percentage indexes of fibrous and organic material are necessary in composting windrows, the replacement of the biocatalyst (feces) by organic sludge, with the purpose of forming an alternative quality fertilizer. Individual windrows were designed with different compositions based on 10 calculations of different proportions. The three different materials used in the composting process for each treatment (T1, T2, T3, T4 and T5 with animal feces as biocatalyst, and T6, T7, T8, T9 and T10, with sludge as biocatalyst). Each treatment consisted of 1kg of material with the following proportions: T1 - 70% of fibrous material and 30% of organic material; T2 - 50% fibrous material and 50% organic material; T3 - 30% fibrous material and 70% organic material; T4 - 10% fibrous material and 90% organic material; T5 - 0% of fibrous material and 100% of organic material, where the following parameters of the organic fertilizers generated were analyzed: physical - granulometry; density and porosity, chemical – Organic Matter; pH; P; K; Ca; Mg; At; SB; Al; H and CTC. All treatments are within the classification range of soil with weak acidity, since the pH and OM content were between 7.01 and 10.8% respectively. Thus, even with the variation of the organic biocatalysts used, the indices and required levels of the physicochemical parameters analyzed, of all treatments, regardless of the fiber content, were above the references expressed in the literature, demonstrating a high quality in the fertilizers produced.

Published: November 2023

This article uses the movie “Hello! Mr. Tree” as the research object, and aims to explore how such a work achieved a word-of-mouth counterattack after several years of its appearance. What kind of magic does it have? Why is it so sought after? Many viewers said they saw themselves in it, what exactly did they see? Through the interpretation of the film and the review of time clues, it is found that in addition to the ingenuity of the film itself, under the changes of the times, the feeling of marginalization in society is also an important reason for the revival of film, and the deep reason for the pervasive feeling of marginalization lies in self-exhaustion and burnout under the meritorious society.
O ensino dos gêneros discursivos em um material didático pautado na semiótica francesa
Authors: Antunes Tiana Andreza Melo
Published: November 2023

Neste trabalho dedicamo-nos a uma reflexão sobre a abordagem de gêneros discursivos em uma obra didática destinada ao sexto ano do ensino fundamental. Como a obra é pautada em conceitos teóricos da semiótica francesa, o objetivo principal é demonstrar como este direcionamento teórico é pertinente para a abordagem dos gêneros discursivos, já que a semiótica greimasiana traz contribuições para a análise de quaisquer textos. Além das contribuições da semiótica francesa, retoma-se o posicionamento de Bakhtin e outros estudiosos para a compreensão da noção de gênero discursivo; também, apontam-se possíveis caminhos para o trabalho com os gêneros conto (a partir da obra eleita) e miniconto, seguindo a linha teórica escolhida. Conclui-se que, para um bom processo de ensino-aprendizagem dos gêneros discursivos, é preciso não somente que o material didático usado seja bem recortado teoricamente, mas também que a utilização de uma linha teórica tem necessidade de um estudo constante por parte dos professores de língua portuguesa.

Which measures predict risk taking in a multi-stage controlled investment decision process?
Authors: Bachmann Kremena , Hens Thorsten , Stossel Remo
Published: November 2023

We assess the ability of different risk profiling measures to predict risk taking along a multistage process that reflects individuals’ discovery of their willingness to take risks. We find that the individual willingness to take risks varies along the process, but its level is always related to a composite measure of the individual risk tolerance. Assessment of the risk tolerance cannot be substituted by a simulated experience, although the latter can improve the perception of the risk and reward potential of the investment and motivate higher risk taking. The risk tolerance measure addresses different notions of risk, but we found that the individual loss aversion is the most powerful predictor of risk taking at all stages of the discovery process. By contrast, we found that neither the self-assessed risk tolerance measures nor the investment experience are suitable for consistently predicting risk taking at different stages of the process.

Introduction: Stroke is one of the leading causes of death worldwide, in majority triggered by modifiable risk factors such as hypertension. AIM: to assess relations between hypertension and carotid arteries radial and circumferential deformation, assessing a population of participants after a first ischemic stroke and healthy controls. Methods: Retrospective study, from 2016 to 2017, with a sample of the PAI project control group, an urban population of the São Francisco Valley in the Northeast of Brazil, 105 people between 40-80 years-old, including patients after a first episode of ischemic stroke in the absence of known cardiovascular disease; and a control group of healthy volunteers, matched by age, sex, and presence of hypertension. Asynchronous analysis was performed by tele-ultrasonography of carotid artery ultrasound with images acquisition of EKG-synchronized videos in cross-section of the common carotid artery bilaterally and then strain values were acquired by Speckle Tracking technique, computing the mean circumferential and radial peaks of both carotids. Univariate and multivariable analyses assessed the association between carotid strain and hypertension. Results: 84 participants had analyzable images (29 patients after a first episode of stroke). The mean age was 60.5 + 11.6 years, 46.5% were women, 70.2% had hypertension. Radial deformation was lower but non-significant in participants with hypertension compared to those without hypertension (-3.13% vs. -3.35%, respectively, p = 0.54). There was significantly less circumferential deformation among participants who had hypertension compared to those without hypertension (4.16% vs. 5.3%, respectively, p = 0.003). Hypertension maintained association with lower circumferential strain in multivariate analysis (coef = -1.13; p = 0.019). Conclusion: hypertension was independently associated with the decrease in the carotid artery circumferential deformation. Tele-ultrasound associated with carotid strain analysis shows promising results for the evaluation of subclinical changes in carotid arteries in populations with limited resources in remote regions such as the Northeast of Brazil.

Introdução: O objetivo principal do estudo é avaliar a concordância entre ultrassonografias mamárias realizadas em um centro especializado em radiologia da mama (exame interno) em comparação com ultrassonografias trazidas pelas pacientes, provenientes de diferentes unidades de atendimento (exame externo), bem como comparar a descrição de lesões sólidas mamárias com relação à sua ecogenicidade, margens e BI-RADS™. Métodos: Ultrassonografias de 62 pacientes foram comparadas. Em 49, o mesmo nódulo sólido foi descrito em ambos os exames e em 44 a classificação BI-RADS™ estava expressa ambos, sendo utilizado para estes casos o coeficiente kappa na análise de concordância. Biópsia com resultado conclusivo foi realizada em 48 pacientes e nestes casos foram calculadas medidas de acurácia para os exames internos e externos. Resultados: Obtiveram-se os seguintes coeficientes kappa:  para ecogenicidade (k = 0,39), margens (k = 0,69), classificação BI-RADS™ (k = 0,40). Destacaram-se nódulos hipoecogênicos (k = 0,62) e a categoria B5 (k = 0,64). Entre os exames externos, sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo foram de 71,4%; 69,2%; 35% e 45%. Nos exames internos os mesmos valores atingiram 86,7%; 78,1%; 65% e 92,6%. Conclusão: A concordância foi leve para ecogenicidade e classificação BI-RADS™, substancial para margens, nódulos hipoecogênicos e categoria B5. Medidas de acurácia foram maiores nos exames internos em relação aos externos.
The Phenomenon Of Al-Takfir: Impacts On Unity Within The Islamic Ummah
Authors: Mohammad Qasim Rashidi  , Habiburrahman Rizapoor
Published: November 2023

The phenomenon of Al-Takfir, characterized by the practice of denouncing fellow Muslims as apostates, has emerged as a critical concern within the Islamic community. This article delves into the detrimental ramifications of Al-Takfir on the unity of the Islamic ummah, elucidating its role as a divisive theological practice that has led to fragmentation within the global Muslim community. Employing an extensive examination of historical occurrences, theological viewpoints, and modern expressions of Al-Takfir, this study scrutinizes its contributory role in eroding the essential unity intrinsic to Islam.
The research underscores that the prerogative of declaring Takfir is not vested in every individual but is relegated to Allah and the Prophet, supported by explicit Quranic verses, authenticated Hadiths, or consensus (Ijma') among Muslim scholars. Similarly, the research underscores that the phenomenon of Takfir has grave repercussions for Muslim unity, as it engenders multiple factions and nurtures mutual animosity among Muslims.
In conclusion, the study proffers strategies aimed at fortifying unity within the Islamic ummah. These strategies encompass raising awareness about the diverse aspects of Islam, promoting dialogue among divergent perspectives, and accentuating the shared values that traverse sectarian divides. Ultimately, this research endeavors to present a nuanced comprehension of the intricate issue of Al-Takfir and its effects on the unity of the Islamic ummah. By providing insights into this multifaceted concern, the study aspires to contribute to the cultivation of a more harmonious and all-encompassing Muslim community.

BACKGROUND

Care partners are essential supports to individuals with multiple sclerosis (MS). Both negative and positive outcomes associated with the caregiving role have been reported. Psychological resilience may be an important factor influencing the MS caregiving experience, but an MS-specific model of care partner resilience has yet to be established. This study sought to explore an explicit model of MS care partner resilience.

METHODS

Cross-sectional data from 471 Canadian MS care partners were collected via an online survey. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used to test measures within a hypothesized model of resilience. Resilience was measured using the 25-item Connor-Davidson Resilience Scale.

RESULTS

Following CFA, the hypothesized model was simplified due to the poor fit of several variables. The final model yielded a moderate SEM fit (χ2 = 6030.95, P < .01). Being a woman was associated with greater caregiving tasks (β = 0.53, P < .001) and poorer spiritual health (β = –0.35, P < .001). Spiritual health, but not caregiving tasks, had a positive impact on both positive (β = 0.48, P < .01) and negative coping (β = 0.49, P = .01). Quality of life and resilience did not have relationships with other variables in the model. However, quality of life had a positive, unidirectional influence on resilience (β = 0.83, P < .01).

CONCLUSIONS

Our findings indicate that spiritual health is an important predictor of coping and should be further explored in MS care partners. Quality of life may act as a precursor to resilience within MS care partners. Further research and exploration into MS care partner resilience is warranted to confirm this exploratory model.

Does thermodynamics still hold true for mecroscopic small systems with only limited degrees of freedom? Do concepts such as temperature, entropy, work done, heat transfer, isothermal processes, and the Carnot cycle remain valid? Does the thermodynamic theory for small systems need modifying or supplementing compared with traditional thermodynamics applicable to macroscopic systems? Taking a single-particle system for example, we investigate the applicability of thermodynamic concepts and laws in small systems. We have found that thermodynamic laws still hold true in small systems at an ensemble-averaged level. After considering the information erasure of the Maxwell’s demon, the second law of thermodynamics is not violated. Additionally, ‘small systems’ bring some new features. Fluctuations in thermodynamic quantities become prominent. In any process far from equilibrium, the distribution functions of thermodynamic quantities satisfy certain rigorously established identities. These identities are known as fluctuation theorems. The second law of thermodynamics can be derived from them. Therefore, fluctuation theorems can be considered an upgradation to the second law of thermodynamics. They enable physicists to obtain equilibrium properties (e.g. free energy difference) by measuring physical quantities associated with non-equilibrium processes (e.g. work distributions). Furthermore, despite some distinct quantum features, the performance of quantum heat engine does not outperform that of classical heat engine. The introduction of motion equations into small system makes the relationship between thermodynamics and mechanics closer than before. Physicists can study energy dissipation in non-equilibrium process and optimize the power and efficiency of heat engine from the first principle. These findings enrich the content of thermodynamic theory and provide new ideas for establishing a general framework for non-equilibrium thermodynamics.

Astrocyte-derived L-lactate was shown to confer beneficial effects on synaptic plasticity and cognitive functions. However, how astrocytic Gi signaling in the anterior cingulate cortex (ACC) modulates L-lactate levels and schema memory is not clear. Here, using chemogenetic approach and well-established behavioral paradigm, we demonstrate that astrocytic Gi pathway activation in the ACC causes significant impairments in flavor-place paired associates (PAs) learning, schema formation, and PA memory retrieval in rats. It also impairs new PA learning even if a prior associative schema exists. These impairments are mediated by decreased L-lactate in the ACC due to astrocytic Gi activation. Concurrent exogenous L-lactate administration bilaterally into the ACC rescues these impairments. Furthermore, we show that the impaired schema memory formation is associated with a decreased neuronal mitochondrial biogenesis caused by decreased L-lactate level in the ACC upon astrocytic Gi activation. Our study also reveals that L-lactate-mediated mitochondrial biogenesis is dependent on monocarboxylate transporter 2 (MCT2) and NMDA receptor activity – discovering a previously unrecognized signaling role of L-lactate. These findings expand our understanding of the role of astrocytes and L-lactate in the brain functions.

In vitro culture systems that structurally model human myogenesis and promote PAX7+ myogenic progenitor maturation have not been established. Here we report that human skeletal muscle organoids can be differentiated from induced pluripotent stem cell lines to contain paraxial mesoderm and neuromesodermal progenitors and develop into organized structures reassembling neural plate border and dermomyotome. Culture conditions instigate neural lineage arrest and promote fetal hypaxial myogenesis toward limb axial anatomical identity, with generation of sustainable uncommitted PAX7 myogenic progenitors and fibroadipogenic (PDGFRa+) progenitor populations equivalent to those from the second trimester of human gestation. Single-cell comparison to human fetal and adult myogenic progenitor /satellite cells reveals distinct molecular signatures for non-dividing myogenic progenitors in activated (CD44High/CD98+/MYOD1+) and dormant (PAX7High/FBN1High/SPRY1High) states. Our approach provides a robust 3D in vitro developmental system for investigating muscle tissue morphogenesis and homeostasis.
