Исследования проводились на спектрометре ЮМО реактора ИБР-2 (ОИЯИ, Дубна). Изучен процесс заполнения-вытекания несмачивающей жидкости (тяжелой воды) из наноразмерных пор материала при изменении внешнего давления. Для этого были спроектированы и изготовлены стенд и камера высокого давления, позволяющие проводить измерения методом МУРН в диапазоне давлений 1–1000 атм. Полученные результаты показывают, что данная методика позволяет исследовать процесс заполнения пор несмачивающей жидкостью в нанопористых материалах.</p></abstract><trans-abstract xml:lang="en"><p>The small-angle neutron scattering (SANS) method was used to study the ordered structure of the pores of the MSM-41 powder coated with a layer of a hydrophobic substance. The studies were carried out on the YuMO spectrometer of the IBR-2 reactor (JINR, Dubna). The process of filling and leakage of a non-wetting liquid (heavy water) from nanosized pores of the material with a change in external pressure was studied. For this purpose, a stand and a high-pressure chamber were designed and manufactured, allowing measurements to be carried out using the SANS method in the pressure range of 1–1000 atm. The results obtained show that this technique allows studying the process of filling pores with a non-wetting liquid in nanoporous materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>малоугловое рассеяние нейтронов</kwd><kwd>нанопористый материал МСМ-41</kwd><kwd>несмачивающая жидкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small-angle neutron scattering</kwd><kwd>nanoporous material MCM-41</kwd><kwd>non-wetting liquid</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках финансирования государственного задания НИЦ “Курчатовский институт”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Feigin L.A., Svergun D.I.
