Authors: Tasliati Djafar  , Wilis Ruhalena , Nurlia Farida  , Elviani
Published: January 2025

This research examines the effect of rice husk biochar and manure on the growth of shallots and the interaction between the two treatments carried out. This research was conducted in Gampong Pineung, Syiah Kuala District, Banda Aceh, from September to December 2023. The method used was a Randomized Block Design (RBD) with a 3x3 factorial design and three replications. The factors tested in this research were the dose of rice husk biochar (0, 10, and 20 tons/ha) and the dose of manure (0, 10, and 20 tons/ha). Several parameters were observed, such as plant height at the age of 15, 30, and 45 dap, the number of tubers per clump at the age of 30 and 45 dap, the weight of wet tubers and dry tubers per clump, and the potential yield per hectare. The results of the research showed that the dose of biochar had a very significant impact on plant height at 30 and 45 dap, the weight of wet tubers, the weight of dry tubers, and the potential yield per hectare. Plant height at 15, 30, and 45 dap, number of tubers per hill at 30 and 45 dap, wet and dry tuber weight per hill, and potential yield per hectare. The study showed that plant height at 30 and 45, wet tuber weight, dry tuber weight, and potential yield per hectare were all significantly affected by biochar dosage. It had no visible impact on the number of tubers per hill at 30 and 45 dap, or on plant height at 15. Plant height at 15 and 30 days was significantly affected by manure application, but plant height at 45 dap, number of tubers per hill at 30 and 45 dap, wet and dry tuber weight, and potential yield per hectare were not affected. In the study of shallot growth and yield results, there was no clear interaction between manure dosage and rice husk biochar

Rumah Masker Tarakan is a business entity in the field of selling cosmetic and skincare products. A common problem faced by Rumah Masker is the placement of products, which often leads to difficulties in finding similar products. Therefore, a method is needed to organize the layout of skincare products that are frequently purchased together, making it easier for customers to select the products they want. The Pincer Search Algorithm, also known as the Two-Way Search, uses two approaches: Top-Down and Bottom-Up. In its process, the primary direction of the Pincer Search is Bottom-Up. The Maximum Frequent Set is a collection of maximal itemsets that are classified as frequent. The purpose of the Maximum Frequent Set is to reduce (prune) the number of candidate Frequent Itemsets that need to be examined in the Bottom-Up process. Based on research conducted using the Pincer Search Algorithm with sales data from January to June 2022, involving a total of 148 data points, it was found that 72 transactions yielded a value of 0.028% for a candidate of 3 itemsets. This demonstrates that the best sales performance occurs with a combination of 3 itemsets.
Hvor vover hun!

Analyzing the Danish media reception of Greta Thunberg’s speech at the UN’s climate action summit in 2019, this article illustrates how anger sticks to Thunberg and the youth climate movement, as wellas how ‘their’ anger is problematized and pathologized. The anger ascribed to Thunberg is framed as a symptom of her autism spectrum diagnosis; as a ‘mental problem’ rather than a reaction to a political problem. Further, ‘her’ anger is portrayed as contagious, posing a risk to the health of other children, and ‘her’ anger becomes the source of ‘our’ concern. The article illustrates this by drawing attention to the emergence of the fi gure of ‘the impossible child’: an angry fi gure who is denied the positive affective status of the Child even though her childishness is constantly emphasized. She is not the innocent Child who must be protected but a problematic child whose dysregulated, pathological anger must be regulated to protect other children from her.
Affective Evictions:
Authors: Gaonkar Anna Meera
Published: January 2025

The article suggests that government statements on anti-ghetto (2021) and security (2020) initiatives feature expressions of ‘white homesickness’ that manifest as longings for a national past and future with less or no migration to Denmark from outside Europe. The analysed statements justify the planned evictions of racialised-migrantised residents of social housing areas. The article argues that the statements also perform ‘affective evictions’ of racialised-migrantised members of society from the community of the imagined national home. Drawing on critical postmigration studies and a media-analytical approach to affect theory, two instrumentalised figures are accentuated as the haunting specters of this homesick politics: the fi gure of insecurity-creating immigrant boys and the figure of parallel societies inhabited by a ‘brown underclass.’ The article concludes that for racialised-migrantised residents of social housing estates in particular, the threat of ‘affective eviction’ paradoxically involves the material threat of eviction from society’s overarching welfare shelter, that is the threat of being deprived of the right to social security.

В статье представлены подробные результаты разработки карт регионального прогноза газодинамических явлений в пределах Гремячинского месторождения калийных солей на основе линейного дискриминантного анализа актуальных геологоразведочных данных. Анализ производился на основе следующих процентных показателей: суммарного содержания нерастворимого остатка и сульфата кальция, содержания хлорида калия и содержания хлорида магния. Особенностью проведенного анализа было его разделение на западную и восточную часть в пределах шахтного поля, что имеет обоснование в статистических и геологических различиях рассматриваемых участков. Полученная результирующая эффективность алгоритма классификации составила 96,6 % и 91,9 % для западной и восточной частей шахтного поля соответственно. Построенные на основе полученных решающих правил прогнозные карты зон, опасных по газодинамическим явлениям, показали высокую адекватность. Полученный алгоритм может быть использован при региональном прогнозировании газодинамических явлений в пределах шахтного поля рассматриваемого рудника.

К АНАЛИЗУ СТАТИСТИЧЕСКИХ АСПЕКТОВ ИЗМЕРЕНИЯ РАСХОДА ВОДЫ В ВОДОТОКАХ НА ОСНОВЕ МЕТОДА РАЗБАВЛЕНИЯ (ХИМИЧЕСКИЙ МЕТОД)
Authors: Лепихин А.П. , Синцова Т.Н. , Богомолов А.В.
Published: January 2025

В настоящее время при решении практических задач появляется необходимость оценки расходов воды в водотоке, имеющем сложную геометрическую форму поперечного сечения русла. Поэтому предложено для решения этих задач использовать метод разбавления, так как он не требует задания скорости течения и площади поперечного сечения, как в традиционных методах измерения. Однако при его широком практическом использовании наблюдается значительная нестабильность измерений расходов воды. Поэтому впервые в данной работе теоретически обоснованы механизмы, определяющие погрешности измерений расходов воды химическим методом. Показано, что высокая неустойчивость результатов измерения расходов воды в водотоках обусловлена самой структурой используемых расчетных зависимостей, при этом колебания расходов воды описываются обратным нормальным распределением, для которого оценки средних значений и дисперсий несостоятельны. Впервые в результате математического моделирования погрешностей измерений расходов воды по схеме Монте–Карло выявлено, что при низкой изменчивости концентрации маркера СvС < 0,1 их оценки состоятельны, а при СvС > 0,25 – неустойчивы. Предложен эффективный способ для повышения устойчивости измерений расходов воды – уменьшение колебаний измеряемых концентраций в контрольном створе.

Does the Temperature of the Distension Medium Affect Pain Perception in Patients undergoing Ambulatory Hysteroscopy?
Authors: Kalmegh Sai , Patvekar Meenal
Published: January 2025

Introduction: Ambulatory Hysteroscopy (AH) has become a valuable tool for modern gynaecologists. However, its success largely depends on the patient’s perception of pain. Advances such as the vaginoscopic technique and the use of smaller instruments have significantly reduced discomfort. Additionally, the use of warm saline as the distension medium is thought to further alleviate pain.

Aim: To compare the degree of pain perceived by patients undergoing office hysteroscopy using normal saline as a distension medium at room temperature with that using normal saline warmed to 37.5°C.

Materials and Methods: A prospective interventional study was conducted at the Department of Obstetrics and Gynaecology, Dr. D. Y. Patil Medical College Hospital and Research Centre, Pimpri, Pune, Maharashtra, India from August 2022 to August 2024. AH was performed on 60 patients using the vaginoscopic technique. Patients were randomly classified into two groups of 30 each. Group A used room temperature normal saline as a distension medium, while Group B used normal saline warmed to 37.5°C. After 15 minutes of the procedure, patients from both groups were asked to rate their level of discomfort throughout the procedure on a 10-cm Visual Analogue Scale (VAS), and the pain scores were compared. The Chi-square test was utilised to determine the association between two independent categorical variables.

Results: The age of the women ranged from 34 to 53 years, with a mean age of 41.77±6.28 years. Among the 60 patients, 40 (66.67%) were premenopausal, and 20 (33.33%) were menopausal. The most common indication was Abnormal Uterine Bleeding (AUB) in 17 (28.3%) patients. Mild pain (0-3) was reported by 15 women in Group A and 24 women in Group B (p-value=0.041). Moderate pain was experienced by 10 women in Group A and 6 in Group B. Severe pain was reported by 5 patients in Group A and none in Group B.

Conclusion: The use of warm saline in AH is a simple, easy and cost-effective method for reducing pain and optimising clinical outcomes.

Published: January 2025

Introduction: Compulsive Buying Disorder (CBD), also known as buying shopping disorder or Oniomania, is a growing concern that affects mental health, relationships, and financial stability. It is characterised by excessive and uncontrollable buying behaviour. With the rise of consumerism and the proliferation of online shopping, compulsive buying has increased, particularly among adolescents and young adults.

Aim: To estimate the prevalence of CBD and identify associated risk factors among undergraduate medical, dental, and nursing students.

Materials and Methods: A cross-sectional study was conducted in the Chengalpattu district of Tamil Nadu, India from November 2023 to March 2024 among undergraduate students from six colleges. A total of 380 students from medical, dental, and nursing disciplines participated in the study. A pretested semistructured questionnaire was used to collect information on socio-demographic details and various risk factors associated with CBD. The validated Richmond Compulsive Buying Scale (RCBS) was employed to determine the prevalence of CBD. Data analysis was performed using Statistical Package for Social Sciences (SPSS) version 22.0.

Results: Among the participants, 232 (61.1%) were female, and 148 (38.9%) were male, with the majority, 272 (71.6%), being under 21 years of age. Educationally, 201 (55.3%) were medical students, while 85 (22.4%) were from nursing and dental disciplines. CBD was observed in 113 (29.7%) of the participants. Significant associations with CBD included female gender, medical education, family history of shopaholics, online shopping, shopping-induced euphoria, anxiety or distress when unable to shop, and lying to family or friends about shopping expenses (p-value <0.05).

Conclusion: The study revealed that 29.7% of undergraduate students exhibited Compulsive Buying Behaviour (CBB). These findings underscore the importance of targeted interventions and awareness campaigns that address identified risk factors, such as gender, academic discipline, family history, and emotional triggers related to shopping. Such efforts could enhance mental health, financial stability, and interpersonal relationships among students.

Authors: Purushotum  , Arya Sushila , Pakpu Tapor
Published: January 2025

The study examined the effects of different phosphorus levels and plant spacing on the growth, yield, and economic viability of black wheat (Triticum aestivum L.), a variety known for its nutritional benefits. The experiment was conducted during the 2023–24 rabi season at the Crop Research Farm of Dev Bhoomi Uttarakhand University in Dehradun, India. A factorial randomized block design with three replications was employed. Four phosphorus levels (40, 50, 60, and 70 kg P₂O₅ ha⁻¹) were applied as diammonium phosphate (DAP) at planting, in combination with three plant spacings (15 cm x 10 cm, 20 cm x 10 cm, and 25 cm x 10 cm).The results showed that 70 kg P₂O₅ ha⁻¹ significantly improved growth parameters, yield attributes, and nitrogen uptake, while the optimal plant spacing of 25 cm x 10 cm further enhanced these outcomes. The highest grain and straw yields were obtained with 70 kg P₂O₅ ha⁻¹, though 60 kg P₂O₅ ha⁻¹ provided similar yields with greater cost-effectiveness. Economic analysis indicated that the combination of 70 kg P₂O₅ ha⁻¹ and optimal spacing (25 cm X 10 cm) resulted in the highest net returns. These findings suggest that strategic phosphorus application, combined with appropriate plant spacing, can improve both the productivity and profitability of black wheat cultivation, offering a sustainable approach to agriculture.

Published: January 2025

Climate change is one of the world's greatest challenges. which creates effects on our forest ecosystem. Sensitivity of forest ecosystem and climate significance affects the growth rate and structure of the forest, and it also have a direct impact on species composition, growth of tress, their mortality and reproduction of trees is also affected by climate change. Increase and decrease in temperature leads to change in time phenology due to which earlier burst of bud, leafing and flowering in trees is affected, this review is all about how climate change affects forest ecosystem. All direct and indirect alterations and shifts in the ecosystems are affected by change in climate. Direct alterations involve temperature changes, precipitation, sea level etc whereas Indirect alteration involves habitat loss and fragmentation, disruption of carbon and nitrogen cycles etc. Examples: Mountain pine beetle (Dendroctonus ponderosae) in north America warmer temperature have extended the breeding season of the mountain pine beetle, Artic species (e.g., Polar bear and walruses). Rise in temperature will affect respiration process due to which photosynthesis rate will also change. Disturbance in climate change. Affects carbon cycle, forest structure, composition of species and alteration in forest ecosystem. Disturbance includes; invasion in species, forest fire, insects and disease outbreaks. Disease outbreaks destroy the structure, composition and function of forest ecosystems. Forest fire also disturbs our forest ecosystem by disturbing wildlife, habitat, increase and decrease in nutrient cycling and mortality of individual. Trees frequency, size, seasonality, intensity due to fire multiplication of pests and pathogen is faster. They expand their range and invade into new regions under warmer, wetter, or carbon dioxide enriched conditions. Nutrient availability is affected by an increase in the temperature through change of organic matter decomposition and mineralization of soil nutrients, mainly nitrogen.
The Impact of Climate Change on the U.S. Insurance Industry and Means of Prevention
Authors: Al-Nimri Ade
Published: January 2025

This research paper examines climate change's effects on the U.S. insurance sector from 1980 to 2023. The paper suggested that to alleviate the effects of climate change, insurers and insurance regulators must improve openness and accountability in their climate risk management and encourage firms to handle climate risks effectively. Furthermore, they must elucidate the appropriate management of climate risk and instruct examiners on circumventing blue-lining, which complicates families' access to affordable insurance and other financial services, thus hindering their capacity to recuperate from the impacts of climate change. Finally, they should select an appropriate external financial services provider, to assess the insurer's operational practices, financial reporting, internal controls, and the general condition of the industry to detect potential risks. then, the service provider devises strategies centered on high-risk insurance categories, ensuring enough field testing to mitigate the risks associated with climate change.

Published: January 2025

This study aimed to evaluate the combining ability (GCA and SCA) and genetic variability among 10 parental wheat lines (7 females and 3 males) and their 21 F1 hybrids using a line × tester mating design. The experiment, conducted at the Research Farm of BRD PG College during the 2021-2022 rabi season, assessed 13 agronomic traits, including plant height, days to flowering, biological yield, and grain yield, using a randomized block design (RBD) with three replications. ANOVA results revealed significant variability among genotypes for all traits except the harvest index, indicating the presence of both additive and non-additive genetic effects. GCA analysis identified PBW-502 and SR-303 as promising parents for early flowering, reduced plant height, and yield-related traits. SCA analysis highlighted hybrids like PBW-502 × DBW-187 and SR-303 × PBW-667 as superior for traits such as early flowering, plant height, and grain yield. These findings provide essential insights for breeders to select suitable parents and hybrids, guiding effective strategies to enhance wheat productivity and agronomic performance.

Authors: Suleiman Mikailu , Iwedi Joy Nkemkanma
Published: January 2025

Rauwolfia vomitoria fruits has been claimed to be used traditionally in treating cancer related diseases. However, this activity has not yet been scientifically proven. This study focused on investigating the cytotoxicity activity of this plant on Tadpoles (Raniceps raninus). The powdered fruits was extracted with methanol and partitioned with n-hexane, dichloromethane and ethyl acetate. The extract and fractions obtained were evaluated for cytotoxic potential in tadpoles. Bioactive fractions were analyzed on Gas chromatography-Mass spectrometry. The n-hexane fraction showed significant cytotoxicity at 20mg/ml, 10mg/ml and 5mg/ml while dichloromethane fraction showed toxicity at 20mg/ml and 10mg/ml. The crude methanol extract and ethyl acetate fraction showed toxicity at 20mg/ml while the aqueous methanol fraction showed no toxicity at all. The GC-MS analysis of n-hexane fraction identified Hexadecenoic acid, methyl ester and three (3) other compounds while that of the dichloromethane fraction revealed n-hexadecenoic acid and three (3) other compounds. This study justifies the use of Rauwolfia vomitoria as an anticancer agent.

Water is an essential component of all life forms.  Its unavailability and inaccessibility are a major concern in developing countries and areas of clean water scarcity.  Wastewater treatment is essential for managing water pollution, protecting public health, and maintaining a sustainable environment. The aim of this work is to treat wastewater using indigenous organic materials such as corn husk and charcoal as filters because of their ability adsorb organic and chemical pollutants in water. The study was carried out by isolating fungal species before and after treatment alongside the changes in physicochemical parameters. The results obtained for the Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO) showed a marked reduction in the treated water by 90%. This constructed trickling filter using charcoal and corn husks were able to remove the color, reduce microorganisms, offensive odor and some chemicals from wastewater. The charcoal and corn husk were cost effective and sustainable. The treated water can be used for irrigation and washing drilling equipment, thereby providing more of this scarce resource in areas it is needed. This answers to the United Nations Sustainable Development Goal (SDGs) 6.

This study addresses a research gap by examining the impact of the voluntary adoption of integrated reporting on company value (TOBINSQ) for companies listed on the Indonesian Stock Exchange. A purposive sampling method was used to select the sample, which included companies with available ESG scores from 2018 to 2022 and accessible annual reports for the same period. The final sample consists of 83 companies, totalling 299 observations. Multiple regression analysis was employed to assess the direct effects of integrated reporting and the moderating role of ESG performance (ESGSCORE) on company value. Our findings reveal that integrated reporting positively influences company value and that ESG performance significantly moderates this relationship, enhancing the benefits of integrated reporting. The results underscore the importance for companies to adopt integrated reporting and enhance ESG performance to improve market valuation. The study also suggests that promoting integrated reporting and ESG disclosures can enhance market transparency and accountability. Future research should focus on longitudinal studies, sector-specific analyses, geographical variations, and the role of digital technologies in integrated reporting and ESG performance to provide deeper insights and practical recommendations.

Efficient catalyst design is crucial for addressing the sluggish multi‐step sulfur redox reaction (SRR) in lithium‐sulfur batteries (LiSBs), which are among the promising candidates for the next‐generation high‐energy‐density storage systems. However, the limited understanding of the underlying catalytic kinetic mechanisms and the lack of precise control over catalyst structures pose challenges in designing highly efficient catalysts, which hinder the LiSBs’ practical application. Here, drawing inspiration from the theoretical calculations, the concept of precisely controlled pre‐lithiation SRR electrocatalysts is proposed. The dual roles of channel and surface lithium in pre‐lithiated 1T’‐MoS2 are revealed, referred to as the “electronic modulation effect” and “drifting effect”, respectively, both of which contribute to accelerating the SRR kinetics. As a result, the thus‐designed 1T’‐LixMoS2/CS cathode obtained by epitaxial growth of pre‐lithiated 1T’‐MoS2 on cubic Co9S8 exhibits impressive performance with a high initial specific capacity of 1049.8 mAh g−1, excellent rate‐capability, and remarkable long‐term cycling stability with a decay rate of only 0.019% per cycle over 1000 cycles at 3 C. This work highlights the importance of precise control in pre‐lithiation parameters and the synergistic effects of channel and surface lithium, providing new valuable insights into the design and optimization of SRR electrocatalysts for high‐performance LiSBs.

Published: October 2023

The Q‐switched material and device have attracted extensive attention due to their irreplaceable role in pulsed lasers. In this paper, BaO–TeO2–WO3 glass (BTW glass) with sound velocity and sound attenuation coefficient of 3422 m−1 s and 0.653 dB cm−1 is successfully selected and fabricated as acousto‐optic material. Both free‐spaced and fiber‐coupled acousto‐optic modulation devices based on BTW glass are designed and fabricated. The primary parameters such as diffraction efficiency, polarization extinction ratio, and insertion loss are comparable to or even surpassed that of commercial devices. A 1064 nm pulsed laser is successfully realized with a BTW glass free‐spaced acousto‐optic modulator. The maximum optical conversion efficiency, the narrowest pulse width, and the maximum single pulse energy of the 1064 nm pulsed laser are 32%, 54 ns, and 242.6 µJ, respectively. Both the device and laser performance indicate that the BTW glass is a remarkable acousto‐optic material.

Here we report the use of a base metal complex [(tBupyrpyrr2)Fe(OEt2)] (1‐OEt2) (tBupyrpyrr22−=3,5‐tBu2‐bis(pyrrolyl)pyridine) as a catalyst for intermolecular amination of Csp3−H bonds of 9,10‐dihydroanthracene (2 a) using 2,4,6‐trimethyl phenyl azide (3 a) as the nitrene source. The reaction is complete within one hour at 80 °C using as low as 2 mol % 1‐OEt2 with control in selectivity for single C−H amination versus double C−H amination. Catalytic C−H amination reactions can be extended to other substrates such as cyclohexadiene and xanthene derivatives and can tolerate a variety of aryl azides having methyl groups in both ortho positions. Under stoichiometric conditions the imido radical species [(tBupyrpyrr2)Fe{=N(2,6‐Me2‐4‐tBu‐C6H2)] (1‐imido) can be isolated in 56 % yield, and spectroscopic, magnetometric, and computational studies confirmed it to be an S = 1 FeIV complex. Complex 1‐imido reacts with 2 a to produce the ferrous aniline adduct [(tBupyrpyrr2)Fe{NH(2,6‐Me2‐4‐tBu‐C6H2)(C14H11)}] (1‐aniline) in 45 % yield. Lastly, it was found that complexes 1‐imido and 1‐aniline are both competent intermediates in catalytic intermolecular C−H amination.
Ligand Modulation of Active Sites to Promote Cobalt‐Doped 1T‐MoS2 Electrocatalytic Hydrogen Evolution in Alkaline Media
Authors: Liu Hai‐Jun , Zhang Shuo , Chai Yong‐Ming , Dong Bin
Published: October 2023

Highly efficient hydrogen evolution reaction (HER) electrocatalyst will determine the mass distributions of hydrogen‐powered clean technologies, while still faces grand challenges. In this work, a synergistic ligand modulation plus Co doping strategy is applied to 1T−MoS2 catalyst via CoMo‐metal‐organic frameworks precursors, boosting the HER catalytic activity and durability of 1T−MoS2. Confirmed by Cs corrected transmission electron microscope and X‐ray absorption spectroscopy, the polydentate 1,2‐bis(4‐pyridyl)ethane ligand can stably link with two‐dimensional 1T−MoS2 layers through cobalt sites to expand interlayer spacing of MoS2 (Co−1T−MoS2‐bpe), which promotes active site exposure, accelerates water dissociation, and optimizes the adsorption and desorption of H in alkaline HER processes. Theoretical calculations indicate the promotions in the electronic structure of 1T−MoS2 originate in the formation of three‐dimensional metal‐organic constructs by linking π‐conjugated ligand, which weakens the hybridization between Mo‐3d and S‐2p orbitals, and in turn makes S‐2p orbital more suitable for hybridization with H‐1s orbital. Therefore, Co−1T−MoS2‐bpe exhibits excellent stability and exceedingly low overpotential for alkaline HER (118 mV at 10 mA cm−2). In addition, integrated into an anion‐exchange membrane water electrolyzer, Co−1T−MoS2‐bpe is much superior to the Pt/C catalyst at the large current densities. This study provides a feasible ligand modulation strategy for designs of two‐dimensional catalysts.

These protocols are atom‐economic, greener, in line with the goal of sustainability, eventually pave the way for numerous novel environmentally benign methodologies. Appealing progress has been achieved in the realm of homogeneous catalysis utilizing noble metals. Owing to their high cost, less abundance along with toxicity issues led the scientific community to search for sustainable alternatives. In this context, earth‐ abundant base metals have gained substantial attention culminating enormous progress in recent years, predominantly with pincer‐type complexes of nickel, cobalt, iron, and manganese. In this regard, group VI chromium, molybdenum and tungsten complexes have been overlooked and remain underdeveloped despite their earth‐abundance and bio‐compatibility. This review delineates a comprehensive overview in the arena of homogeneously catalysed (de)hydrogenation reactions using group VI base metals chromium, molybdenum, and tungsten till date. Various reactions have been described; hydrogenation, transfer hydrogenation, dehydrogenation, acceptorless dehydrogenative coupling, hydrogen auto transfer, along with their scope and brief mechanistic insights.

Zum absoluten Einzelelektrodenpotential
Authors: Bagchi S. N.
Published: October 2023

Der Elektrodenprozeß kann als eine Reaktion vom Typ \documentclass{article}\pagestyle{empty}\begin{document}$ \mathop A\limits_ - \rlhar2 \mathop A\limits_ = ^ + $\end{document} + Θ Gleichung (1) angesehen werden. Die freie Energie dieser Reaktion ist dann ein Maß für das absolute Einzelelektrodenpotential an der Grenzfläche. Der Vorteil dieses Verfahrens liegt darin, daß die Differenz der aus derartigen Reaktionen berechneten absoluten Einzelpotentiale für zwei Elektroden direkt die Differenz der gemessenen Normal‐potentiale ergibt. Die absoluten Elektrodenpotentiale, die aus der freien Energie des üblichen Elektrodenprozesses \documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {A^ + }\limits_ - \rlhar2 \mathop A\limits_ = ^ + $\end{document} Gleichung (2) berechnet werden können, unterscheiden sich dagegen von den gemessenen Normalpotentialen um das Galvanipotential zwischen den beiden Elektroden. In dieser Arbeit wird gezeigt, daß E1 — E2 = Eh2 = E'1 — E'2 + 1G2 ist, und daß somit die beiden Methoden konsistent sind. Was man wirklich unter dem absoluten Elektrodenpotential verstehen soll, ist dann tatsächlich nur eine Frage der Konvention und Definition. Das durch Gleichung (1) gegebene Potential kann als absolutes Einzelelektrodenpotential und das durch Gleichung (2) bestimmte als absolutes Grenzflächenpotential definiert werden.
A preliminary report on the adsorption of water vapor by silver iodide
Authors: Coulter L. V. , Candela G. A.
Published: October 2023

Adsorption isotherms of water on silver iodide have been determined by the volumetric at 16.0°, 34.0° and 50.0°C. Normal surface adsorption was accompanied by a phase transition at P/P0 ∼ 1/2 which appeared to be the formation of a chemical hydrate by a surface impurity. After correcting for this effect, a type III isotherm was obtained. The isosteric heat of adsorption was found to be ∼1 kcal. less than the heat of liquefaction of water at the same temperature and is in qualitative agreement with the energy of adsorption calculated from the B.E.T. theory and the Hüttig equation.
Die Abhängigkeit der Gleichgewichtsgalvanispannung von kleinen Anfangskonzentrationen auf Grund der potentialbestimmenden Ionenadsorption
Authors: Lange E. , Schücker J.
Published: October 2023

Die Ausbildung der Gleichgewichtsgalvanispannung eines elektrochemischen Zweiphasensystems ist mit einer potentialbestimmenden Ionenadsorption verbunden. Durch diese Ionenadsorption kann eine vorgegebene Anfangskonzentration der potentialbestimmenden Ionen bis zu einer von dieser merklich verschiedenen Endkonzentration nach Einstellung des elektrochemischen Gleichgewichts verändert werden. Diese Konzentrationsänderung ist um so größer, je kleiner die Anfangskonzentration ist.

Es wird daher quantitativ untersucht, in welchem Maße die Galvanispannung von der vorgegebenen Anfangskonzentration abhängt. Die Ergebnisse werden durch, graphische Darstellungen an Hand einiger Beispiele veranschaulicht.

Dabei lassen sich für die einfache Elektrode zwei charakteristische Fälle der Abhängigkeit der Galvanispannung von der Anfangskonzentration angeben. In beiden Fällen wird die Galvanispannung bei sehr kleinen Konzentrationen unabhängig von der Anfangskonzentration. Während aber bei hohen Nullkonzentrationen c0 der konzentrationsunabhängige Endwert von dem spezifischen Dipolanteil gD wenig abhängig ist, geht er bei kleinen Nullkonzentrationen in diesen spezifischen Dipolanteil gD über.

Für die 2:1,1fache Elektrode im elektrochemischen Doppelgleichgewicht sind bezüglich der Lage der Nullkonzentration und des Löslichkeitsproduktes drei Fälle unterscheidbar. Ist das Löslichkeitsprodukt größer als 10−16/1−2, so hängt die Galvanispannung im gesamten Konzentrationsgebiet geradlinig vom Logarithmus der praktisch unverändert bleibenden Anfangskonzentration ab. Dagegen weicht der Verlauf hiervon bei Elektroden mit kleinerem Löslichkeitsprodukt je nach der Lage der Nullkonzentration ab; und zwar erhält man bei großen Nullkonzentrationen in einem Gebiet beiderseits der Äquivalenzkonzentration einen von der Anfangskonzentration unabhängigen Verlauf der Galvanispannung. Bei kleinen Nullkonzentrationen ist die Abhängigkeit von der Anfangskonzentration ähnlich, nur ist die Galvanispannung in dem von der Anfangskonzentration unabhängigen Bereich zahlenmäßig gleich gD.
Zur Kalorimetrie der Hochpolymeren: I. Bestimmung von integralen Verdünnungswärmen über den gesamten Konzentrationsbereich
Authors: Gorke K. , Jenckel E.
Published: October 2023

Es wird ein adiabatisches Differentialkalorimeter beschrieben, mit dem es möglich ist, integrale Verdünnungswärmen von 2 · 10−2 cal, entwickelt in etwa zwei Minuten, bei Zimmertemperatur zu messen. Das zur Verfügung stehende Volumen Lösungsmittel beträgt 800cm3. Die infolge von Temperaturdifferenzen (etwa 10−5 bis 10−6 Grad) auftretenden Thermospannungen (etwa 10−8 Volt) einer hochempfindlichen Thermosäule werden von einem Photozellenkompensator verstärkt, kompensiert und von einem elektrischen Schreiber alle 10 sec notiert. Die Homogenität der zu verdünnenden Ausgangskonzentration kann durch beliebig langes Warten vor dem Versuch, die restlose Verdünnung durch kleine Einwaagen und gute Rührung während des Versuchs erreicht werden. Das Kalorimeter wird elektrisch geeicht. Eine besondere Konstruktion der Thermosäule erlaubt es, Eich‐ und Meßkurven zu vergleichen, obwohl die elektrische Arbeit beim Eichen konstant je Zeiteinheit, die im Versuch umgesetzte Arbeit jedoch nicht konstant je Zeiteinheit frei wird. Auf diese Weise werden Wärmeausgleichsrechnungen vermieden.
