В работе рассматривалась возможность использования нановолокон оксида алюминия марки «Алюминан» в химических никель-фосфорных (Ni-P) покрытиях. Были проведены исследования морфологии полученных композиционных покрытий и их структуры. Показано, что введение нановолокон алюминия в никель-фосфорную матрицу снижает пористость покрытий, а также увеличивает микротвердость покрытий, подвергшихся термообработке, подтверждая их армирующее действие. Нановолокна марки «Алюминан» могут быть рассмотрены как перспективный материал для использования в металлических покрытиях.
The paper considered the possibility of using aluminum oxide nanofibers of the Aluminan brand in chemical nickel-phosphorus (Ni-P) coatings. The morphology of the obtained composite coatings and their structure were studied. It is shown that the introduction of aluminum nanofibers into a nickel-phosphorus matrix increases the microhardness of coatings subjected to heat treatment, confirming their reinforcing effect. Nanofibers of the Aluminan brand can be considered as a promising material for use in metal coatings.

Published: January 2025

Расчетно-теоретическим методом проведена оценка влияния замены полимерного связующего на основные термодинамические характеристики модельных метательных композиций. В качестве полимера-заменителя использованы полинитрополифенилен (PNP) и сополимер хлортрифторэтилена/винилиденфторида (KFL-F800). Их выбор обусловлен высокой плотностью (от 1,6 г/см3 до 2,2 г/см3), термостабильностью, применением в качестве вяжущих составов пиротехнических и взрывчатых композиций. В качестве наполнителей для модельных составов использовались соединения: наполнители 3-нитро-1,2,4-триазол-5-он (NTO), 1,3,5-триамино-2,4,6-тринитробензол (TATB), 1,1-диамино-2,2-динитроэтен (FOX-7), динитрамид N-гуанилмочевины (FOX-12), 1,3,3-тринитроазетидин (TNAZ); модификаторы горения 1,9-диазидо-2,4,6,8-тетранитро-2,4,6,8-тетраазанонан (ДИАЗ-4) и 2,4-динитротолуола (ДНТ). Расчётным методом показано: применение PNP в качестве связующего уменьшает силу пороха на 2,8 % в смеси с TNAZ, с остальными наполнителями увеличивает силу от 0,5 % до 3,6 %; применение KFL-F 800 приводит к снижению силы от 3,4 % до 6,3 % для всех видов наполнителя. При этом суммарное увеличение температуры находится в диапазоне от 1,7 % до 13,8 % что может ограничить спектр потенциального применения составов.
The influence of the polymer binder change on the main thermodynamic characteristics of model propellant compositions was evaluated by the computational and theoretical method. Polyinitro-polyphenylene (PNP) and a copolymer of chlorotrifluoroethylene/vinylidene fluoride (KFL-F 800) were used as a substitute polymer. Their choice is due to their high density (from 1.6 g/cm3 to 2.2 g/cm3), thermal stability (, the use of pyrotechnic and explosive compositions as binders. The following compounds were used as fillers for model formulations: fillers 3-nitro-1,2,4-triazole-5-one (NTO), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), 1,1-diamino-2,2-dinitroethene (Aprol, FOX-7), dinitramide of N-guanylurea (FOX-12), 1,3,3-trinitroazetidine (TNAZ); gorenje modifiers 1,9-diazido-2,4,6,8-tetranitro-2,4,6,8-tetraazanonane (DIAZ-4) and 2,4-dinitrotoluene (DNT). The calculated method (for compositions without gorenje modifiers) shows: the use of PNP as a binder reduces the strength of gunpowder by 2.8% in a mixture with TNAZ, with other fillers increases the strength from 0.5% to 3.6%; the use of KFL-F 800 leads to a decrease in the strength of gunpowder from 3.4% to 6.3% for all types of filler. At the same time, the total temperature increase is in the range from 1.7% to 13.8%, which may somewhat limit the range of potential applications of the formulations.

Published: January 2025

Полиморфизм является одной из важнейших характеристик индивидуальных ВВ, так как полиморфы одного и того же ВВ обладают разными физико-химическими и взрывчатыми параметрами. Получение требуемых полиморфных модификаций CL-20 является важной практической задачей и предопределяет актуальность исследований. Целью данной работы является получение β- и g-CL-20 методом осадительной перекристаллизации с оценкой морфологических свойств частиц порошков и идентификацией кристаллических полиморфов по ИК-спектрам поглощения. Рассмотрены две системы осадительной перекристаллизации CL-20 этилацетат/хлороформ и ацетонитрил/толуол. В зависимости от скорости дозировки осадителя возможно получение частиц β- и g-CL-20 размерами от 5 до 140 мкм и от 4 до 210 мкм, соответственно. Методом инфракрасной спектроскопии идентифицированы β- и g- полиморфные модификации. Показана возможность сокращения времени исследований за счёт исключения пробоподготовки прессовок образцов CL-20 с KBr для инфракрасной спектроскопии.
Polymorphism is one of the most important characteristics of individual explosives, since polymorphs of the same explosives have different physico-chemical and explosive parameters. Obtaining the required polymorphic modifications of CL-20 is an important practical task and determines the relevance of research. The aim of this work is to obtain β- and γ-CL-20 by precipitation recrystallization with an assessment of the morphological properties of powder particles and identification of crystalline polymorphs by IR absorption spectra. Two systems of sedimentary recrystallization of CL-20 ethyl acetate/chloroform and acetonitrile/toluene are considered. Depending on the dosage rate of the precipitator, it is possible to obtain β- and γ-CL-20 particles with sizes from 5 to 140 microns and from 4 to 210 microns, respectively. β- and γ-polymorphic modifications have been identified by infrared spectroscopy. The possibility of reducing the study time by eliminating sample preparation of CL-20 samples with KBr for infrared spectroscopy is shown.

Сохранение свойств веществ под воздействием различных факторов всегда было и остается актуальным. Именно стабильность физических и химических свойств веществ напрямую влияет на стабильную работу изделий и их целевые характеристики. Целью работы является оценка разработанного нами ранее способа сольватотермической модификации поверхностей неорганических солей наноразмерным оксидом меди (II) в качестве средства защиты веществ от воздействия влаги. В работе представлены материалы экспериментальных исследований по снижению влагопоглощения нитрата калия и перхлората калия путем нанесения на их поверхность различных защитных покрытий. В качестве защитных покрытий в работе рассматривались фторопласт Ф-42Л, наноразмерный оксид меди (II) и их комбинация. Оценку влагопоглощения производили гравиметрическим способом. Влагопоглощение исследуемых солей проводили по ГОСТ 24816-2014. В результате проведенных экспериментов было установлено, что сольватотермическая модификация поверхности неорганических солей не уступает в защите образцов от воздействия влаги полимерным материалам, а комбинация покрытий из сольватотермического нанооксида меди и фторопласта значительно снижает степень влагопоглощения.
Preservation of properties of substances under the influence of various factors has always been and remains relevant. It is the stability of physical and chemical properties of substances that directly affects the stable operation of products and their target characteristics. The aim of the work is to evaluate the previously developed method of solvothermal modification of surfaces of inorganic salts with nanosized copper (II) oxide as a means of protecting substances from moisture. The work presents materials of experimental studies on reducing moisture absorption of potassium nitrate and potassium perchlorate by applying various protective coatings to their surface. Fluoroplastic F-42L, nanosized copper (II) oxide and their combination were considered as protective coatings in the work. Moisture absorption was assessed gravimetrically. Moisture absorption of the salts under study was carried out according to GOST 24816-2014. As a result of the experiments, it was established that the solvothermal modification of the surface of inorganic salts is not inferior to polymeric materials in protecting samples from the effects of moisture, and the combination of coatings made of solvothermal copper nanooxide and fluoroplastic significantly reduces the degree of moisture absorption.

Методами дифференциальной сканирующей калориметрии и термогравиметрического анализа определены термические свойства составов, особенности термолиза и химическая совместимость компонентов. Проведённые исследования показали, что связующие на основе полимера МПВТ-А, пластифицированные динитратпропиленгликолем, либо нитроаминами с нитроэфирами, полностью совместимы с кристаллическим окислителем 4,10-динитро-2,6,8,12-тетраокса-4,10-диазатетрцикло[5.5.0.05,9.03,11]-додеканом и совершенно не совместимы с 5-нитро-1,2-дигидро-3Н-1,2,4-триазин-3-ОН.
The article presents the results of experimental studies of the thermal characteristics of high-energy compounds of low-sensitivity oxidants 5-nitro-1,2-dihydro-3H-1,2,4-triazine-3-ONe, 1,3,5-triamino-2,4,6-trinitrobenzene and 4,10-dinitro-2,6,8,12-tetraox-4,10-diazatetrcyclone[5.5.0.05,9.03,11]-dodecane with tetrazole binders based on poly-N-methyl-5-vinyltetrazole allylated (MPVT-A). The methods of differential scanning calorimetry and thermogravimetric analysis have determined the thermal properties of the compositions, the features of thermolysis and the chemical compatibility of the components. Studies have shown that binders based on the MPVT-A polymer, plasticized with dinitrate propylene glycol or nitroamines with nitroesters, are fully compatible with the crystalline oxidizer 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetrcyclone[5.5.0.05,9.03,11]-dodecane and are completely incompatible with 5-nitro-1,2-dihydro-3H-1,2,4-triazine-3-ONE.

Kesejahteraan seorang ibu rumah tangga (IRT) penuh waktu memiliki peranan yang sangat penting bagi semua anggotanya, yaitu mencakup kesejahteraan emosional dan fisik. Sampel dalam penelitian ini merupakan IRT penuh waktu yang mengalami burnout dan berdampak terhadap kesejahteraaan keluarga. Banyak perempuan berpendidikan tinggi meninggalkan pekerjaan dan memutuskan menjadi IRT penuh waktu. Namun seiring berjalannya waktu, IRT penuh waktu mengalami burnout akibat rutinitas baru. Burnout disebabkan oleh pekerjaan rumah tangga dan pengasuhan anak yang tidak pernah selesai dalam kehidupan sehari-hari sehingga mengakibatkan kelelahan fisik dan psikis. Resiliensi merupakan kemampuan untuk bangkit kembali dalam mengatasi stres. Penelitian ini terdiri dari dua variabel, yaitu resiliensi sebagai variabel bebas dan kesejahteraan subyektif ibu sebagai variabel terikat. Kedua alat ukur tersebut adalah Subjective Well-being for Mother (SWBM) dan Connor-Davidson Resilience Scale (CD-RISC). Metode kuantitatif korelasional digunakan dalam penelitian ini. Kuesioner disebarkan kepada 317 IRT yang sebelumnya bekerja minimal enam bulan dan masih memiliki anak usia sekolah. Burnout dapat terjadi pada IRT penuh waktu mana pun tanpa memandang usia, pendidikan, dan status sosial ekonomi. Penelitian ini membuktikan bahwa resiliensi memberikan dampak yang baik bagi IRT penuh waktu yang mengalami burnout untuk memperoleh kembali kesejahteraan dirinya.

IntroductionManagement of infected burn wounds should include clinical diagnosis, pathogen identification, wound care, surgical debridement, and targeted antibiotic therapy.AimThis article highlights the usage of an atypically stored split-thickness skin graft (STSG) in infected burn wounds and affirm that burn wound closure with STSG application is the standard of care.Case studyWe present a case of infected burn wounds in an elderly patient. Intraoperatively, her condition deteriorated and surgery had to be terminated abruptly. We were unable to apply the harvested STSGs. The meshed STSGs were refrigerated at 4°C after being wrapped in chlorhexidine-impregnated paraffin gauze and saline-moisturized gauze. On day 4 of storage, the STSGs were applied to Pseudomonas aeruginosa infected wounds, post-debridement. Graft take was 100% during subsequent review.Results and discussionIf the wounds are debrided thoroughly and targeted antibiotic administered, STSG application on infected burn wounds might not be absolutely contraindicated. When appropriately stored, time sensitive STSGs can still be used to achieve wound closure.ConclusionsA simple storage method of STSGs using chlorhexidine and saline warrants further research.
