На основании проведенных экспериментальных исследований, направленных на исследование микроструктуры и элементного состава титановых порошков для аддитивных машин, полученных электродиспергированием металлоотходов сплава ОТ4 в воде, показано, что процесс быстрой кристаллизации расплавленного ОТ4 в жидкой рабочей среде способствует приданию частицам сферической формы с содержанием в них основных элементов Ti и Al. Титановые порошковые материалы сферической формы, получаемые ЭД отходов титанового сплава ОТ4, могут эффективно использоваться для аддитивных машин.
Based on the conducted experimental studies aimed at studying the microstructure and elemental composition of titanium powders for additive machines obtained by electrodispersing metal waste from OT4 alloy in water, it is shown that the process of rapid crystallization of molten OT4 in a liquid working medium contributes to giving the particles a spherical shape with the content of the main elements Ti and Al in them. Spherical titanium powder materials obtained from waste titanium alloy OT4 can be effectively used for additive machines.

Моделирование трения и изнашивания углеродных материалов представляет собой сложную задачу, т.к. материалы обладают уникальными свойствами, такими как высокая твердость, хрупкость и химическая инертность. В контактных парах, например, «металл–углеродный материал» происходят сложные физико-химические процессы, связанные с наличием продуктов износа в зоне контакта, высокой температурой и ряда других факторов. Трение и изнашивание этих материалов играют важную роль в промышленности: станкостроении и двигателестроении, металлообработке, при создании узлов машин и механизмов различного назначения. Регрессионный анализ в моделировании трения и изнашивания углеродных материалов позволяет выявить зависимости между различными факторами, влияющими на эти процессы. Это необходимо для прогнозирования и оптимизации параметров, таких как уменьшение трения и износа в различных трибологических системах, что позволяет предсказать поведение системы при различных условиях. Эти необходимо при разработке исследуемых материалов и технологий, что может значительно повысить их эффективность и долговечность.
The simulation of friction and wear of carbon materials is a changeling task because these materials have unique properties, such as high hardness and brittleness and chemical inertness. In contact pairs, e.g., "metal–carbon material" complex physical and chemical processes take place due to the presence of wear products in the contact zone, high temperature etc. Friction and wear of these materials play an important role in industry: machine tool and engine building, metalworking, creating machine units for various purposes. Regression analysis in simulation of friction and wear of carbon materials helps us to identify the correlations of various factors affecting the wear process. This simulation is indispensable for predicting and optimizing friction and wear parameters, which allows us to predict the behavior of friction system under various conditions and significantly increase their efficiency and durability.

FIQH'S CONTRIBUTION TO SUSTAINABLE DEVELOPMENT
Authors: Agustiar  
Published: February 2025

Sustainable development is a global challenge that requires a holistic approach, including economic, social and environmental dimensions. Countries with a majority Muslim population have the potential to utilize fiqh, as a system of Islamic law and ethics, to support sustainable development. This research aims to explore the contribution of fiqh to sustainable development and public policy. Using a qualitative approach and descriptive-analytical design, this research examines relevant literature, analyzing policy documents. The research results show that fiqh provides a strong ethical and normative foundation to support sustainable development. Fiqh principles such as justice ('adl), public benefit (maslahat), and amanah (trust) are very relevant in overcoming the challenges of sustainable development. Analysis of policy documents reveals that although there are initiatives to integrate fiqh principles in public policy, implementation is still limited and sporadic. In conclusion, fiqh has great potential to contribute to sustainable development by offering strong ethical and normative guidance for creating a more just and sustainable society. It is recommended that future research conduct in-depth case studies in countries with a majority Muslim population to evaluate the implementation of fiqh principles in sustainable development policies, as well as analyze their effectiveness on sustainable development indicators. In addition, it is important to develop a practical framework for the implementation of fiqh principles, conduct comparative studies with other countries, examine the role of stakeholders, and assess the impact of educational programs and public awareness. Long-term evaluation is also needed to measure the real impact on sustainable development and community welfare.

ImportanceIn-hospital mortality of patients with sepsis is frequently measured for benchmarking, both by researchers and policymakers. Prior studies have reported higher in-hospital mortality among patients with sepsis at safety-net hospitals compared with non–safety-net hospitals; however, in critically ill patients, in-hospital mortality rates are known to be associated with hospital discharge practices, which may differ between safety-net hospitals and non–safety-net hospitals.ObjectiveTo assess how admission to safety-net hospitals is associated with 2 metrics of short-term mortality (in-hospital mortality and 30-day mortality) and discharge practices among patients with sepsis.Design, Setting, and ParticipantsRetrospective, national cohort study of Medicare fee-for-service beneficiaries aged 66 years and older, admitted with sepsis to an intensive care unit from January 2011 to December 2019 based on information from the Medicare Provider Analysis and Review File. Data were analyzed from October 2022 to September 2023.ExposureAdmission to a safety-net hospital (hospitals with a Medicare disproportionate share index in the top quartile per US region).Main Outcomes and MeasuresCoprimary outcomes: in-hospital mortality and 30-day mortality. Secondary outcomes: (1) in-hospital do-not-resuscitate orders, (2) in-hospital palliative care delivery, (3) discharge to a postacute facility (skilled nursing facility, inpatient rehabilitation facility, or long-term acute care hospital), and (4) discharge to hospice.ResultsBetween 2011 and 2019, 2 551 743 patients with sepsis (mean [SD] age, 78.8 [8.2] years; 1 324 109 [51.9%] female; 262 496 [10.3%] Black, 2 137 493 [83.8%] White, and 151 754 [5.9%] other) were admitted to 666 safety-net hospitals and 1924 non–safety-net hospitals. Admission to safety-net hospitals was associated with higher in-hospital mortality (odds ratio [OR], 1.09; 95% CI, 1.06-1.13) but not 30-day mortality (OR, 1.01; 95% CI, 0.99-1.04). Admission to safety-net hospitals was associated with lower do-not-resuscitate rates (OR, 0.86; 95% CI, 0.81-0.91), palliative care delivery rates (OR, 0.66; 95% CI, 0.60-0.73), and hospice discharge (OR, 0.82; 95% CI, 0.78-0.87) but not with discharge to postacute facilities (OR, 0.98; 95% CI, 0.95-1.01).Conclusions and RelevanceIn this cohort study, among patients with sepsis, admission to safety-net hospitals was associated with higher in-hospital mortality but not with 30-day mortality. Differences in in-hospital mortality may partially be explained by greater use of hospice at non–safety-net hospitals, which shifts attribution of death from the index hospitalization to hospice. Future investigations and publicly reported quality measures should consider time-delimited rather than hospital-delimited measures of short-term mortality to avoid undue penalty to safety-net hospitals with similar short-term mortality.
Clinical value of nano‐carbon lymphatic tracer for regional lymph node dissections of rectal cancer after neoadjuvant chemoradiotherapy

Published: May 2024

AbstractObjectivesRegional lymph node (LN) volume decreases after neoadjuvant therapy, requiring a tracer for more accurate detection. Nano‐carbon tracer is a third‐generation tracer with several advantages, but its use for LN detection after neoadjuvant chemoradiotherapy for middle and low rectal cancer remains unclear. Therefore, this study investigated the effects and safety of anoscope‐guided subrectal injections of nano‐carbon suspension in this patient population.MethodsThis study retrospectively reviewed the medical records of 45 patients with middle and low rectal cancer admitted to our institution from March 2019 to March 2022. All patients received preoperative neoadjuvant chemotherapy and radiotherapy and were divided into nano‐carbon injection (n = 23; anoscope‐guided injections of nano‐carbon suspension in the rectal submucosa 2 cm above the dentate line 24 h preoperatively) and control (n = 22; directly underwent surgery) groups. The LN detection and complication rates were compared between the groups.ResultsThe total and mean numbers of LNs and small LNs and the number of patients with > 12 LNs were significantly higher in the nano‐carbon injection group than in the control group. The total number of positive LNs and LN metastasis did not differ between the groups, nor did the anastomotic leakage, bleeding, stenosis, and abscess occurrence rates.ConclusionsAnoscope‐guided nano‐carbon lymphatic tracing increased the LN detection rate, caused less trauma, and resulted in fewer postoperative complications than the direct surgical procedure. Thus, it is an effective, safe, and practical method that may improve dissections and the postoperative pathological staging accuracy.

AbstractIn response to the increasing demand for spheroid‐based cancer research, the importance of developing integrated platforms that can simultaneously facilitate high‐throughput spheroid production and multiplexed analysis is emphasized. In addition, the understanding of how the size and cellular composition of tumors directly influence their internal structures and functionalities underlines the critical need to produce spheroids of diverse sizes and compositions on a large scale. To address this rising demand, this work presents a configurable and linkable in vitro three‐dimensional (3D) cell culture kit (CLiCK) for spheroids, termed CLiCK‐Spheroid. This platform consists of three primary components: a hanging drop microarray (HDMA), a concave pillar microarray (CPMA), and gradient blocks. The HDMA alone produces a homogeneous spheroid array, while its combination with the gradient block enables one‐step generation of a size‐gradient spheroid array. Using the size‐gradient spheroid arrays, the occurrence of necrotic cores based on spheroid size is demonstrated. Additionally, spheroids in a single batch can be conveniently compartmentalized and regrouped using a CPMA, enhancing the versatility of spheroid arrays and enabling multiplexed drug treatments. By combining the different assembly methods, this work has achieved high‐throughput production of cell composition‐gradient spheroid arrays, with noticeable variations in morphology and vascularization based on cell compositions.

Published: May 2024

AbstractPathological ocular neovascularization resulting from retinal ischemia constitutes a major cause of vision loss. Current anti‐VEGF therapies rely on burdensome intravitreal injections of Bevacizumab (Beva). Herein ultrasmall polymeric micelles encapsulating Beva (P@Beva) are developed for noninvasive topical delivery to posterior eye tissues. Beva is efficiently loaded into 11 nm micelles fabricated via self‐assembly of hyperbranched amphiphilic copolymers. The neutral, brush‐like micelles demonstrate excellent drug encapsulation and colloidal stability. In vitro, P@Beva enhances intracellular delivery of Beva in ocular cells versus free drug. Ex vivo corneal and conjunctival‐sclera‐choroidal tissues transport after eye drops are improved 23‐fold and 7.9‐fold, respectively. Anti‐angiogenic bioactivity is retained with P@Beva eliciting greater inhibition of endothelial tube formation and choroid sprouting over Beva alone. Remarkably, in an oxygen‐induced retinopathy (OIR) model, topical P@Beva matching efficacy of intravitreal Beva injection, is the clinical standard. Comprehensive biocompatibility verifies safety. Overall, this pioneering protein delivery platform holds promise to shift paradigms from invasive intravitreal injections toward simplified, noninvasive administration of biotherapeutics targeting posterior eye diseases.

AbstractTwo‐photon excited fluorescence materials with sufficient responsiveness to magnetic field are essential for applications such as 3D mapping of magnetic field distributions based on magneto‐optical effect. In this study, a two‐photon excited magneto‐photoluminescence (MPL) in the intermolecular exciplex of 1,1‐bis[(di‐4‐tolylamino)phenyl]cyclohexane and tris(2,4,6‐trimethyl‐3‐(pyridin‐3‐yl)phenyl)borane (TAPC:3TPYMB) is observed. This MPL can be attributed to the promotion of delocalization of excitons in the exciplex under two‐photon excitation, resulting in a weakened spin‐exchange interaction and thereby enhancing the magnetic field‐sensitive spin conversion process. The temperature‐dependent MPL further validates the strong correlation between the delocalization of excitons in the exciplex and the enhanced MPL observed during temperature variation. Combining the penetration capability and magneto‐optical effect of two‐photon excited fluorescence in TAPC:3TPYMB exciplex, a novel magnetic sensor suitable for 3D mapping of magnetic field distributions is further developed. The present work not only enhances the understanding of the magneto‐optical coupling mechanism but also opens up opportunities for the application of molecular materials in opto‐spintronic devices.

AbstractInorganic CsPbI3 perovskite has great potential to fabricate deep‐red light‐emitting diodes (LEDs) owing to excellent color purity, thermal stability, and carrier mobility. However, fabricating high‐quality CsPbI3 thin films for high‐performance LEDs remains challenging. While it is demonstrated that hydrogen bonds between organic ammonium cations and molecule additives can lead to high‐quality organic–inorganic hybrid perovskite films, this method cannot be applied to CsPbI3 thin films due to the absence of hydrogen bonds between Cs+ ions and additives. In this study, an amorphous complex‐seed‐crystal growth process to fabricate high‐quality γ‐CsPbI3 cuboid crystallite thin films, is reported. During the initial annealing, the metastable intermediates formed crystal nucleate seeds and transformed into amorphous complex intermediates, maintaining stability at an elevated temperature for perovskite crystallization. With prolonged annealing, the amorphous complex around the nucleate seeds gradually converts to γ‐CsPbI3 perovskite, enabling us to fabricate CsPbI3 thin films with high crystallinity and orientation. The resulting deep‐red LEDs exhibit a peak external quantum efficiency (EQE) of 16.5% and a high maximum luminance of 3158 cd m−2. Moreover, the devices show significantly suppressed efficiency roll‐off, maintaining an EQE of 14.8% even under a high current density of 500 mA cm−2.

Published: May 2024

AbstractAn In(III)‐catalyzed [2+3+1] annulation strategy is developed for the diastereoselective construction of diversely functionalized tetrahydroxanthones bearing chromone rings. This protocol is based on a three‐component reaction involving various 3‐formylchromones and α‐methylstyrenes via a carbonyl‐ene and formal [4+2] cycloaddition reaction. Notable features of this reaction include its wide substrate scope, high tolerance towards functional groups, atom economy, and excellent diastereoselectivity. In addition, the synthesized tetrahydroxanthones are readily transformed into 2‐hydroxybenzophenone products.
Electrochemical Synthesis of Trifluoromethylated Oxazoles: Aminotrifluoromethylation of Alkynes/in‐situ Cyclization
Authors: Jang Jihoon , Cho Eun Jin 
Published: May 2024

AbstractWe report the development of a four‐component electrochemical method for the synthesis of CF3‐oxazoles, utilizing alkynes and NaSO2CF3 in MeCN. The method leverages the simplicity and mildness of the reaction conditions, despite the inherent complexity of utilizing four distinct components through aminotrifluoromethylation of alkyne followed by in‐situ cyclization. Notably, in addition to MeCN solvent, the presence of residual water in the reaction mixture also contributed as a coupling partner. The synthesis involves a sequence of four controlled oxidation steps under constant potential with graphite electrodes, facilitated by the mediator TMEDA, highlighting the precision achievable in electrochemistry.
