Authors: Masic Fatima , Saric Mirza , Hivziefendic Jasna , Dzemic Zijad
Published: October 2024

The increased installation of distributed generators in the electrical network presents significant challenges for system planners and operators, demanding strategic adaptations to accommodate diverse energy sources while ensuring grid stability and operational efficiency. HC analysis has recently been proposed as an essential tool capable of guiding investments into the areas of the network, most likely to offer optimal benefits. This paper presents a method for the estimation of photovoltaic HC of the distribution network. For this purpose, the OpenDSS program, employing the Monte Carlo-based method, is utilised to quantify the HC of the electrical distribution network. The simulation is conducted using a real electrical MV network and then verified against the IEEE Test System for validation. The paper reports HC of 166.5%, which is higher in comparison with similar methods and models, investigates the influence of constant generation in daily simulation and proves that voltage constraint is violated before line loading. A considerable increase of the circuit losses is recorded if the optimal penetration of PV is exceeded. The main contribution of this work is the development, testing and implementation of the HC estimation method in complex power systems using open-source tools and integrating them in an innovative fashion. The results of this research will contribute to collective endeavours of energy transition and a sustainable future.

The article has obtained an analytical solution to the thermal conductivity equation for the contact connection of long sections of overhead lines, and also considered the case for a line with two short and two long sections, which makes it possible to take into account distributed defects and clamp sizes. The application of the obtained mathematical model to determine the temperature of an overhead power line near contact connections is shown. A comparative analysis of the temperature values in the power line, calculated using the created mathematical model, with published data obtained based on finite element modeling using the results of a physical experiment is performed. It has been shown that heating of contact connections can significantly limit the throughput of lines even at an acceptable level of contact resistance. This makes relevant the tasks of calculating the temperature of contact connections of power lines and clarifying permissible currents taking into account the influence of transient contact resistances.
Overcoming dead-end situations of synthesis of motions of anthropomorphic robots on the basis of the use of motions of the clutch axis along the linear surface limiting the body angle of service
Authors:   Omsk State Technical University, Pritykin F. N.
Published: October 2024

An algorithm for synthesizing hand motions of anthropomorphic robots by velocity vector during the installation of objects of manipulation given, in the form of rectangular prisms in a container, is proposed. The algorithm makes it possible to solve deadlock situations in computer simulation of motions. The essence of the method consists in the use of hand motions, at which the axis of the clash carrier moves and forms with some approximation a rulered surface, which specifies the body angle of service. For this purpose, it is proposed to use a database of configurations that specify certain positions of the output link centre and of the accumulation carrier axes which coincide with the above-mentioned line surfaces. The results of calculations of intermediate configurations in computer modeling of motions of anthropomorphic robots in an organized environment using the developed algorithm are presented.

The article presents the results of studies of profile joints of mechanisms and machines for rigidity and strength. The device is based on the use of fixed and movable profile connections designed to transmit torque. Profile joints with a guaranteed gap are considered, made on the basis of an equiaxial contour of the P3, P5 type and a curved contour of the PC4 type, which have received the most widespread introduction in the nodes of metal-cutting machines and other machines manufactured in Russia, as well as Hungary, Germany and the DPRK. Using a well-known technique designed to assess the stress-strain state (VAT) of the parts of profile joints, calculations are performed according to the criteria of operability for strength and stiffness of hubs (bushings) with different wall thicknesses. The analysis of the results of the calculation of strength and stiffness is carried out using the example of the P3 profile. When stretching the hub from the action of spacer forces, the geometric shape, the nominal size of the covered part, the wall thickness of the covering part, as well as the magnitude of the external load transmitted by the connection in static are taken into account. The permissible values of the thickness of the walls of the hub (bushings) of the joint are determined to ensure the rigidity of the hub under tension from the action of external loads. As a result of the research, the influence of the thickness of the hub walls for the studied shapes of the joint parts on the values of the transmitted torque is established. For example, a change in the thickness of the hub wall from 15 to 3 mm for a normal range of shaft mounting diameters causes the sleeve to stretch radially up to 50 microns in the range of transmitted torques from 5 to 600 Nm.

Prompt receipt of reliable information about the terrain with sufficient detail is one of the main tasks in the fields of national economy, territorial development or research of large territorial units. The multiplicity of error sources in Earth remote sensing materials is due to a number of factors, and the resulting terrain models have a certain degree of generalization, which directly affects the correctness of digital terrain models. This article is devoted to the analysis of existing methods for estimating errors of open digital terrain models in order to increase their accuracy. Correct digital elevation models have a high similarity to reality and can be used in regional studies to determine the morphometric indicators of the territory.

Authors:   Saint Petersburg State University of Aerospace Instrumentation, Kuzmenko V. P.
Published: October 2024

Modern energy systems are increasingly integrating renewable energy sources, presenting new challenges for voltage regulation. This study aims to model the voltage regulation process in the context of distributed electrical grids equipped with solar photovoltaic systems. A three-tier voltage control algorithm is proposed, which analyzes and integrates data on solar generation, suggests optimal actions for managing energy storage systems, calculates voltage levels, and recommends measures for controlling inverter reactive power to effectively mitigate voltage fluctuations. The study employs methods of mathematical averaging of time series and optimization based on the analysis of real data. The algorithm's performance is evaluated using an open dataset of solar energy generation. The results show a significant improvement in voltage regulation metrics, conforming to the standards established by GOST 32144-2013. This validates the effectiveness of the proposed voltage control method in electrical grids incorporating solar photovoltaic systems.

A supraciliary subcutaneous browlift for tattooed eyebrow ptosis
Authors: Beraja Gabriela Esther , Beraja Victor
Published: October 2024

Patients with eyebrow ptosis often remove their natural eyebrow hairs and tattoo the skin above the brow in their desired position. Frequently, these tattooed brows are drawn significantly higher than their actual anatomical location, resulting in an artificial appearance. By extending the incision laterally into the temporal region and meticulously undermining the subcutaneous tissue beneath the eyebrow, supraciliary, and temporal regions, we can effectively correct ptosis and achieve the creation of more esthetically pleasing tattooed brows.
EVALUATING GROWTH AND NUTRIENT COMPOSITION OF AFRICAN CATFISH UNDER DIFFERENT SALINITIES

Published: October 2024

An investigation was carried out to explore the effect of salinity on the growth and flesh quality of African catfish (Clarias gariepinus), a significant species in global aquaculture. Fifty juvenile catfish of weight 24.25±0.4g were collected from the Chenab River in Pakistan and acclimatized in controlled aquaculture conditions at different salinity levels NaCl (T1; 0, T2; 2, T3; 4; T4; 6, and T5; 8 ppt) over 60 days. Growth performance indicators, including final weights, weight gain, growth rate, and feed conversion ratio (FCR), were measured. The statistical result indicated that the fish in lower salinity environments (0-2 ppt) exhibited significant (p < 0.05)  final weights, weight gain, and growth rates, with performance declining significantly as salinity increased. The best FCR 1.2±0.01 was indicated at 0 ppt, while the highest salinity (8 ppt) was revealed in the FCR 1.7±0.04. Proximate composition analysis indicated that crude protein and moisture content elevated with salinity while crude fat and ash content decreased. These results suggest that C. gariepinus thrives in slightly brackish conditions, with optimal growth at low salinity levels. However, higher salinities adversely impact physiological health and growth performance.
Reducing Recommender System Biases: An Investigation of Rating Display Designs
Authors: Adomavicius Gediminas , Bockstedt Jesse C. , Curley Shawn P. , Zhang Jingjing
Published: October 2024

Prior research has shown that online recommendations have a significant influence on consumers’ preference ratings and economic behavior. Specifically, biases induced by observing personalized system recommendations can lead to distortions in users’ self-reported preference ratings after consumption of an item, thus contaminating the users’ subsequent inputs to the recommender system. This, in turn, provides the system with an inaccurate view of user preferences and opens up possibilities of rating manipulation. As recommender systems continue to become increasingly popular in today’s online environments, preventing or reducing such system-induced biases constitutes a highly important and practical research problem. In this paper, we address this problem via the analysis of different rating display designs for the purpose of proactively preventing biases before they occur (i.e., at rating collection time). We use randomized laboratory experimentation to test how the presentation format of personalized recommendations affects the biases generated in post-consumption preference ratings. We demonstrate that graphical rating display designs of recommender systems are more advantageous than numerical designs in reducing the biases, although none are able to remove biases completely. We also show that scale compatibility is a contributing mechanism operating to create these biases, although not the only one. Together, the results have practical implications for the design and implementation of recommender systems as well as theoretical implications for the study of recommendation biases.
ТЕНТАТИВ ИССЛЕДОВАНИЯ ОНОМАСТИЧЕСКОГО МАТЕРИАЛА НАЦИОНАЛЬНЫХ ВЕРСИЙ ЭПОСА «КЫЗ ЖИБЕК»
Authors:   Independent Researcher, RAKHIMOV Adil
Published: October 2024

It is believed that the recording and publication of the Kazakh lyrical epic Kyz Zhibek took place at the end of the 19th century. The beginning of the collection, study and scientific research of numerous versions of the poem, including by foreign scientists, dates back to the beginning of the 20th century. The relevance of this work is seen against the background of unresolved problems of folkloristics of the past period concerning the genesis of the lyrical epic work Kyz Zhibek, which became common to a number of Turkic peoples. The novelty of the research is that for the first time a comparison was made of the main national versions of the poem in the Kazakh and Nogai languages, as well as their translations into other Turkic languages. The purpose of this article is an attempt to attract the attention of industry specialists and to submit for scientific discussion the hypothesis of reception and transformation of onomastic terminology of the main variants of the Kyz Zhibek epic in the context of existing ethnolinguistic issues. The main objective of the work is to compare the main epic objects: the ethnonym Zhagalbaily from the Kazakh versions of the epic and the toponym Yagalybaily, found in its Nogai versions. In a comparative analysis of the content of the text of various versions of the epic in Kazakh (Kyz Zhibek, Kyz Zhibek hikayasi Kissa) and Nogai (Kyz-Yibek, Tolegen men Kyz-Yibek) languages, as well as their translations into Kyrgyz (Kyz Jibek), Russian (Kyz Jibek), Turkish (Kizcibek Destani, Kız Jibek Destanı) and Uzbek (Kizzhibak, Qiz jibek and Qiz-Jibek) languages were used comparatively historical method. As a result of the conducted research, it was found that if in the Kazakh versions of the epic Zhagalbaily is the name of the Kazakh tribe, then in its Nogai versions Yagalybaily is the name of the area. At the same time, in the national versions of the epic of both peoples, they look like interchangeable terms. It is noteworthy that the events described in both cases take place on the Black Sea coast. Excerpts from the text of the epics, which contain Zhagalbaily and Yagalybaily, look like a calculated translation. In our opinion, further research to establish the etymological ambiguity of the onyms Zhagalbaily and Yagalybaily seems promising. It is of scientific interest to establish the factors of amplification and contamination that influenced the processes of plot composition of national versions of the Kyz Zhibek epic. It is proposed to discuss the possibility and expediency of conducting further research aimed at studying the considered synonyms in relation to each other from the point of view of the theory of binary oppositions (ethnonym – toponym; toponym – ethnonym) and from the point of view of the concept of etymological nests.
СПОСОБЫ ВЫРАЖЕНИЯ СРАВНЕНИЯ В ФОЛЬКЛОРЕ БАРАБИНЦЕВ (по материалам В. В. Радлова и Л. В. Дмитриевой)

The language of the Baraba Tatars, an indigenous small Turkic-speaking ethnic group living in the Novosibirsk Region, is considered to be severely endangered. Its levels are extremely poorly understood. The purpose of this article is to study the ways of expressing comparativity based on the material of this idiom and such study is being conducted for the first time. To achieve this goal, folklore texts presented mainly by dastans, i. e. heroic tales, published in two works: V. V. Radlova “Samples of folk literature of Turkic tribes living in Southern Siberia and the Dzungarian steppe” and L. V. Dmitrieva “The language of the Baraba Tatars” were analyzed. An approach developed in the Sector of Languages of the Peoples of Siberia at the Institute of Philology of the Siberian Branch of the Russian Academy of Sciences was used to analyze the linguistic material. In the course of the study, the following ways of transmitting comparativity were identified: 1) the equivalence is expressed by affixes =taw / =täw; =lai / =läi and =layin / =läyin; predicates of similarity osha= ʻto be similarʼ, oqsha= ʻto be similarʼ; analytical index bolyp; parametric name sorlugu ʻthe same size asʼ; and other means – words shägällü ʻsimilarʼ, käbäk ʻsimilar, alikeʼ, tagynnajyn ʻthe same wayʼ; 2) differentiation of the compared objects is achieved both by lexical means – the words artyk ʻbetter, best ʼ, eng ʻthe mostʼ, otary ʻmore and more ʼ, kichӓ, kichyӓ ʻlessʼ, and with the help of the affix of comparison =rak / =rӓk. In most cases, the parameter and/or comparison standard is expressed implicitly and is deduced from the context. Examples from each group are represented by an uneven number of units. On the one hand, this may indicate a different frequency of use of certain ways of expressing comparison, on the other hand, genre features may have imposed restrictions on usage. In general, the considered comparisons have analogues in other Turkic languages, but also have a certain uniqueness, which can be accounted for by the transitional nature of the language of the Baraba Tatars – from the South Siberian Turkic languages to the languages of the Urals and the Volga region, as well as Central Asia. In the future, it is planned to consider the use of comparative concepts based on the material of the colloquial speech of the Barabians.

Проблема совершенствования машиностроительных производств приобретает первостепенное значение. Требуемая точность высокоточных изделий достигается при традиционных методах изготовления усложнением технологического оборудования и использованием информационных и измерительных технологий. В настоящее время функциональная точность высокоточных изделий превзошла точность обрабатывающего и сборочного оборудований почти на порядок. Это привело к возникновению проблемы достижения заданного качества и точности высокоточных изделий при их изготовлении. На сегодняшний день наблюдаются разрозненные решения отдельных задач этой проблемы, отсутствует наиболее приближенная к реальным требованиям концепция системы в целом. В данной статье формируется структура комплекса проектных процедур, который основывается на установлении связи между технологической подготовкой механообрабатывающего и сборочного производств. Также в статье рассматриваются математическая модель представления и анализа деталей и сборок (исходными данными являются полученные графы сопряжений сборочной единицы и графы размеров) и подход для автоматизации расчета технологических размерных цепей (исходными данными являются граф технологического процесса и размерные цепи).

The problem of improving machine-building production is of paramount importance. The required precision is achieved with the traditional methods of manufacturing. They are: the complication of the processing equipment and the applying of the information technologies and measurement technologies. At present, the functional precision of the high-precision products (the devices and the machines) has surpassed the precision of the machining equipment and the assembly equipment almost by a decade. This leads to the problem of the achieving of the specified quality and accuracy of the high-precision products during their manufacture. Now there are just the segmental solutions for some specific tasks of these issues, such as the upgrading of the quality and the precision of the production, the reduction of the material costs, the adoption of the resource-saving technologies and so on. But the unifying vision of the system meeting the real requirements does not exist. In the present paper the discipline of the holistic approach (complex of design procedures) which provide the effectiveness of the realization of the assembly operations is considered. The effective realization of the assembly operations is based on the links between the process design of the manufacturing of the high-precision products and the process design of the assembly production of the high-precision products. Moreover, mathematical models and approaches of realization of the complex are considered in this paper.

В статье представлена феноменологическая модель кавитационной интенсификации химических реакций в высокоинтенсивном ультразвуковом поле. В основе предложенной модели лежит статистический подход, который заключается в оценке константы скорости химической реакции, усредненной по объему. Усреднение проводится по объему, который намного больше, чем объем кавитационного пузырька, в котором микроскопическое значение постоянной зависит от ударного волнового давления при коллапсе кавитационных пузырьков.  Константа скорости химической реакции зависит от давления и рассчитывается с использованием распределения скоростей молекул Максвелла и вероятности события, что энергия молекулы больше энергии  активации для данной реакции. Численный анализ модели показал, что ультразвуковое воздействие повышает эффективность химических реакций в 1,5 раза.

The model is based statistical approach which is evaluation of volume-averaged chemical reaction rate constant. Averaging is performed over volume that is much more than cavitation bubble volume in which the microscopic value of constant depends on shock wave pressure at cavitation bubbles collapse. The chemical reaction constant dependency on pressure is calculated by using Maxwell distribution of molecules velocities and probability of event that the molecule energy is more than activation energy for given reaction. The numerical analysis of model shown that ultrasonic influence increase of chemical reaction efficiency up to 1.5 times.

Рассматривается роль прокурора в арбитражном судопроизводстве. Законодатель наделил прокурора полномочиями, связанными с обращением с исковым заявлением в арбитражный суд для защиты публичных интересов или путем опротестования судебных актов в рамках надзорного производства. Прокурор как участник судебного процесса может выступать и в качестве третьего лица, его могут привлекать к рассмотрению спора в особых случаях. Сложности заключаются в разграничении полномочий: прокурор представляет публичные интересы, но также может выступать в защиту интересов конкретных лиц, он может участвовать в процессе от имени государственного или муниципального органа. В связи с этим определение конкретной роли прокурора довольно затруднительно.

The role of the prosecutor in arbitration proceedings is considered. The legislator has vested the prosecutor with powers related to filing a claim with the arbitration court to protect public interests or by challenging judicial acts within the framework of supervisory proceedings. The prosecutor as a participant in the trial can also act as a third party; he can be involved in the consideration of a dispute in special cases. The difficulties lie in the delineation of powers, because the prosecutor represents public interests, but can also act in defense of the interests of specific individuals; he can participate on behalf of a state or municipal body. Therefore, it is quite difficult to determine a specific role.

The first total synthesis of the cyclic depsipeptide antibiotic LL-A03411-beta1 (LL) is described. The configuration of the -methyltryptophan (-MeTrp) residue was established by preparing all four stereoisomers of Fmoc--MeTrp which were used for the synthesis of LL via Fmoc solid phase peptide synthesis. The most active of the four peptides was the one containing (2R,3R)--MeTrp. The activity of LL was strongly inhibited by cardiolipin (CL), but not other common phos-pholipids found in bacterial cell membranes suggesting that LL interacts with CL in the lipid membrane
Decoding Aromaticity in the [24]paracyclophanetetraene Anions
Authors: Szczepanik Dariusz , El Bakouri Ouissam , Wieczorkiewicz Paweł
Published: October 2024

Paracyclophanetetraene (PCT) anions are known for their extraordinary stability that determines cycling performance under fast-charge/fast-discharge conditions, making PCT a suitable material for energy storage in batteries. In previous studies, it was suggested that the unique energy-harnessing capabilities of PCT are associated with the redox-based aromaticity switching from local 24𝜋-aromaticity (PCT) through global 26𝜋-aromaticity (PCT2-) to 28𝜋-antiaromaticity (PCT4-), in accordance with the famous 𝜋-electron bookkeeping rules by Hückel ("4n+2" / "4n"). In this work, however, we call into question this interpretation by showing that the ability of PCT to accumulate up to four electrons is associated with the superposition of the ionic forms that represent the migration of multiple 𝜋-sextets in accordance with Clar's rule. Our findings challenge existing paradigms and offer insight into the resonance-electronic structure of the conjugated macrocycles to better understand the origins of their exceptional electron-transport capabilities and thermodynamic stability.

Pharmacological inhibition of cGAS-STING-controlled innate immune pathway is an emerging therapeutic strategy for a myriad of inflammatory diseases, including autoimmune disease, ulcerative colitis, non-alcoholic fatty liver disease and aging-related neurodegeneration. Here we report GHN105 as an orally bioavailable covalent STING inhibitor. Late-stage diversification of the briarane-type diterpenoid excavatolide B allowed the installation of solubility-enhancing functional groups while enhancing its activity as a covalent STING inhibitor against multiple human STING variants, including the S154 variant responsible for a genetic autoimmune disease. Selectively engaging the membrane-proximal Cys91 residue of STING, GHN105 dose-dependently inhibited cGAS-STING signaling and type I interferon responses in cells and in vivo. Orally administered GHN105 exerted marked therapeutic efficacy and reversed key pathological features in a delayed-treatment acute colitis mouse model. Notably, we also showed that GHN105 covalently engaged STING in the colon tissues. Our study provided proof of concept that synthetic briarane analog GHN105 serves as a safe and orally active covalent STING inhibitor. With a growing number of chronic inflammatory diseases linked to aberrant STING activation, orally bioavailable STING inhibitors would benefit patients by lowering the infection risk from frequent injections while allowing long-term systemic administration.

Understanding the oxidation behavior of Pt nanoparticles (NPs) is crucial for developing durable and efficient catalysts. In this study, we investigate the oxidation of a realistic Pt NP, retrieved from scanning transmission electron microscopy (STEM) images. We use a multistep approach combining ReaxFF and MACE-MP-0 forcefields with Density Functional Theory (DFT) calculations. Our Monte Carlo simulations reveal high oxidation of the nanoparticle, with oxygen penetrating deep into the core. We explore the plausibility of these configurations by carrying out XRD, TEM and EXAFS measurements on samples of various average particle sizes. Progressing in our workflow, we find that 100 ns of thermostated dynamics at 350 K using the ReaxFF forcefield leads to the formation of detached Pt$_6$O$_8$ species. To explore the validity of this small platinum-oxide cluster, we first optimize the geometries using the recent MACE-MP-0 forcefield resulting in structures without the species. We then compare both forcefields to DFT calculations showing closer agreement for MACE-MP-0 compared to ReaxFF. Finally, we discuss the electronic structure of our oxidized nanoparticles spanning a whole range of oxygen coverages, finding substantial changes in the Pt-5$d$ and O-2$p$ projected density of states of the platinum structure as the coverage increases. Our findings emphasize the importance of accurately describing the potential energy surface and explicitly modeling oxygen coverage to predict catalytically relevant properties at high potentials. This study aims to provide a foundation for understanding the complex interplay between nanoparticle structure, oxidation state, and catalytic performance, aiming to guide the rational design of advanced catalytic materials.

Published: October 2024

Metal hydrides (MHs) are promising candidates for hydrogen storage due to their high volumetric energy densities and safety features. Recent developments suggest hydride systems can cycle and operate at pressures and temperatures favorable coupling with fuel cells for stationary long-duration energy storage applications. In this study, we present a conceptual design of a metal hydride-based storage system for backup power (0 to 20 MW supplied over 0 to 100 hours), and benchmark system cost and performance. Leveraging experimental hydrogen absorption and desorption data, we determine the uptake/release of hydrogen across likely pressure and temperature conditions, and estimate the equipment power, upfront capital cost, levelized cost of storage, land footprint, and energy density for a select number of metal hydrides and hypothetical operation scenarios. Our findings indicate that hydride-based storage systems hold significant size advantage in physical footprint, requiring up to 65% less land than the 170-bar compressed gas storage options. Metal hydride systems can be cost competitive with 350-bar compressed gas systems, with TiFe0.85Mn0.05 achieving $0.453/kWh and complex MH 2Mg(NH2)2-2.1LiH-0.1KH achieving $0.383/kWh, compared to $0.397/kWh for 350 bar compressed gas in the base case scenario. However, these advantages are sensitive to charging and discharging rate requirements, operational cycles and material manufacturing prices. Extending charging times and increasing operating cycles significantly reduce LCOS, especially for complex MHs, making them more competitive for applications with slow charging and long duration energy storage needs. Key strategies to further enhance the competitiveness of MHs include leveraging waste heat from fuel cells, increasing hydrogen uptake, and achieving metal hydride production costs of US$10/kg.
A bright organic fluorophore for precise measurement of the relative quantum yield in the NIR-II window

Organic dyes with photoluminescence in the second near-infrared window (NIR-II, 1000–1700 nm) are essential in bioimaging and optoelectronic devices. Photoluminescence quantum yield (PLQY) is their important performance indicator. Integrating sphere technology is effective in determining the absolute PLQY. However, the low emission brightness of most NIR-II organic fluorophores results in unacceptable errors. Therefore, the most common method for determining the PLQY is a relative approach using photoluminescence spectrometers and a standard reference like IR-26. Although the relative method can obtain accurate PLQY ratios between the samples and references, the specific PLQY value of IR-26 is not clearly defined, which is reported to range from 0.05% to 0.50%. Such a deviation can cause significant errors in relative PLQY measurements. In this study, a bright organic fluorophore called TPE-BBT exhibits a high PLQY of 4.17% in THF, which can be accurately measured using a commercially available integrating sphere. Using TPE-BBT as a standard reference, we have determined the PLQY values of IR-26 in DCE to be 0.0301% and IR-1061 in DCM to be 0.193%.

Gas-phase photothermal reactions using metallic catalysts have attracted increasing attention recently due to their potential for reducing activation energy and improving reaction selectivity. However, many challenges remain, including the validation of non-thermal contributions with accurate temperature measurement, strategies to enhance the non-thermal contribution, and its microscopic understanding. Here we propose using metallic nanostructures instead of metal oxide powder as catalyst support to eliminate the challenge in temperature measurement and further enhance the non-thermal contribution. We choose CO2 methanation using Ru on Ti nanostructures to demonstrate this idea. Ru-decorated Ti nanostructures are fabricated using two-step pulsed laser irradiation on Ti foil. Several-fold enhancements in CH4 production rate are observed under 1 sun illumination in the 150-350 ℃ temperature range. More than a 100-fold enhancement in reaction rate is achieved with white light alone as both the thermal and photon sources. The non-thermal contribution is further confirmed by the observations that only blue light (445 nm) accelerates the reaction rate while green (525 nm) and red (665 nm) light have no effect. The wavelength-dependent enhancement and atomic-scale Ru catalysts lead us to conclude that the non-thermal contribution is due to the direct photo-excitation of CO2 adsorbed on the Ru catalysts, and this excitation is further enhanced by the near-filed of Ti nanostructures. The idea of nanostructured metallic support and our experimental approach can be applied to other photothermal reactions to achieve high activity and mechanistic understanding.
Ultimate Strategy for Preventing Metal Nanoparticle Sintering in Polymer Derived Mesoporous SiCN Ceramics
Authors: Thayuman Saravanakumar , Kempe Rhett
Published: October 2024

Polymer-derived ceramics (PDCs) are increasingly recognised as robust supports for high-temperature catalysis. However, the efficiency of these catalysts is often compromised by the sintering of metal nanoparticles, which reduces the surface area available for efficient interaction with reactants. This article introduces a new synthetic approach to prevent nanoparticle sintering through co-polymerization, microphase separation, and pyrolysis. An efficient version of HD-Polyethylene synthesised via Ziegler’s Aufbaureaktion and aminopyridinato gold complex as a porogen block and precursor for the generation of gold nanoparticles respectively. Particularly, a commercially available precursor derived siliconcarbonitride (SiCN) is used as a model PDC to demonstrate effective prevention of gold nanoparticle sintering, in contrast to conventional methods that often lead to particle agglomeration. The successfully synthesised Au@SiCN catalyst overcoming the sintering phenomenon is characterised using transmission electron microscopy, scanning electron microscopy, atomic force microscopy, powder X-ray diffractometry, and nitrogen physisorption techniques. Our findings highlight the effectiveness of this innovative synthetic approach in maintaining nanoparticle dispersion as well as enhancing the performance of PDCs for catalytic and energy applications.
