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.

Published: January 2025

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.

Understanding the viscosity and phase state of biomass-burning organic aerosol (BBOA) from wildfires and pyrocumulonimbus (pyroCb) events in the stratosphere is critical for predicting their role in stratospheric multiphase chemistry and ozone depletion. However, the viscosity and phase state of BBOA under stratospheric conditions, including interactions with sulfuric acid (H₂SO₄), remain largely unquantified. In this study, we combine laboratory data with a thermodynamic model to predict the viscosity and phase state of BBOA under stratospheric conditions. Our results suggest that BBOA with a H₂SO₄-to-BBOA mass ratio of 0.37—an estimated upper limit for pyroCb smoke in the lower stratosphere after two months of aging— is highly viscous and frequently exists in a glassy state. Even at a higher H₂SO₄-to-BBOA mass ratio of 0.79 – an estimated upper limit after nine months of aging – BBOA can still transition to a glassy state under certain stratospheric conditions. In the glassy state, bulk reactions are suppressed, and multiphase chemistry may be limited to the particle surfaces. We also highlight key areas for future research needed to better constrain the viscosity and phase state of BBOA in the stratosphere and its subsequent impact on ozone.
Dual-responsive phosphorus-based fluorescent sensors: synthesis and selective metal sensing of pyrazolyl phosphine oxides
Authors: Calder Ethan , Hawes Isobel , Jupp Andrew
Published: January 2025

Despite a wealth of previously reported frameworks for fluorescent metal sensors, there are few examples of phosphorus-based fluorophores being used in metal sensing applications. Here, we report the synthesis and characterisation of a new family of pyrazolyl-phosphine oxides and their use in metal sensing applications. The mechanism of their formation has been probed in detail with both computational and experimental studies, rationalising the selectivity of the reaction. Their use as dual-responsive fluorescent metal sensors is then demonstrated, with ‘turn-off’ and ‘turn-on’ responses observed for Fe3+ and Al3+, respectively. These systems exhibit good selectivity, large Stokes shifts, and submicromolar limits of detection, and will open new avenues in phosphorus-based fluorophores and metal-sensing applications.

Breast cancer, the most commonly diagnosed disease worldwide, has been linked to the overexpression of the kinesin Eg5 protein, a spindle motor protein crucial for the assembly and maintenance of the bipolar spindle during mitosis. This makes Eg5 an attractive therapeutic target for tumor treatment. To address the urgent need for effective treatments for this lifethreatening illness, we utilized generative AI to design novel and potential inhibitors of this protein. In this study, a generative LSTM model was pretrained on SMILES data from ChEMBL and subsequently fine-tuned using SMILES of compounds with reported activity against the Eg5 protein. The fine-tuned model generated valid compounds, which were screened using a machine learning model, drug-likeness filters, molecular docking, and molecular dynamics (MD) simulations conducted over 200 ns. Five novel compounds with better binding affinities to Eg5 compared to the co-crystallized ligand were identified. The top compound, Compound 103 (a bioisostere of the co-crystallized ligand), demonstrated a significantly improved binding free energy (-82.68 kcal/mol) compared to the co-crystallized ligand (-76.98 kcal/mol), as determined by MM-GBSA calculations. ADMET predictions and MD simulations further confirmed that the top compounds interacted effectively with the target protein and exhibited drug-like properties. This study shows the potential of generative AI to explore our vast chemical space and find promising drug candidates. However, further in vitro and in vivo studies are needed to confirm the predicted biological effects of the top compounds.

Published: January 2025

A commercial QqTOF platform (ZenoTOF 7600 system) was modified to enable three fragmentation modes, collision induced dissociation (CID), electron activated dissociation (EAD) and ultraviolet photodissociation (UVPD) at 266 nm. 168 pesticides, which showed fragmentation in CID provides also EAD spectra. In the case of UVPD, 158 compounds fragmented under 266 nm photon irradiation. The performance of the novel platform was evaluated using data independent CID SWATH acquisition for the general screening and schedule multiple product ion acquisition with CID/EAD/UVPD for confirmatory analysis of pesticides in juice, white and red wines samples. A column-switching LC method with online dilution was developed allowing for injection of large volumes (80 μL) into the system. The approach enabled the detection and concentration estimation of approximately thirty pesticides in juices and wines, including insecticides, neonicotinoids and fungicides. Pesticide LODs were found to be in the pg/ml to ng/ml range for MS1 and MS2 acquisitions.

Authors: Das Ishita , Ghosh Anupam , Buragohain Dipankar
Published: January 2025

Coastal areas are transition zones and hence, are susceptible to dynamic changes. To understand the seasonal changes in benthic foraminiferal distribution, a study based on surface sampling was carried in two distinct sub-environments – intertidal flats (Bakkhali, Fraserganj) and marsh areas (Patibhunia and Henry’s Island). Two short cores (~16 cm) were procured to observe the changes in foraminiferal signatures from top sediment surface to down the core. The characteristic foraminiferal population consists of Ammonia beccarii, Ammonia tepida, Asterorotalia pulchella, Haynesina depressula, Haynesina germanica, Nonionella labradorica, Nonionella turgida, Quinqueloculina seminulum, Cribroelphidium hispidulum, Cribroelphidium poeynum, Trochammina inflata, Miliammina spp., Haplophragmoides canariensis, Haplophragmoides wilberti and Ammodiscus evolutus. The abundance of foraminifera increases from tens to few hundreds and species richness increases from 4 to 8 on an average as we move from the western locations to the eastern locations of the study area. Agglutinated species were dominant in the marsh areas whereas, the intertidal flat consists of calcareous forms. Overall, the diversity of foraminiferal assemblages is poor.
