Физико-химические свойства сорбента на основе силикагеля с привитым комплексом медьацетоуксусного эфира
Authors: Пахнутова Евгения Андреевна , Слижов Юрий Геннадьевич 
Published: December 2021

Нанопористые минеральные оксиды способны радикально менять свои физико-химические свойства в результате химического модифицирования поверхности, что способствует развитию методов направленного синтеза материалов на их основе и широкому применению в условиях газовой хроматографии. Целью данной работы является получение газохроматографического сорбента с привитым слоем медьацетоуксусного эфира методом последовательной сборки на поверхности Силохрома С-120 через стадию его хлорирования.
Данные термического анализа свидетельствуют об устойчивости исследуемого комплекса этилацетоацетата меди до 210°С. Методом адсорбционной порометрии установлено, что в результате химического модифицирования SiO2 происходит сокращение площади удельной поверхности и пористости. По результатам элементного анализа рассчитаны количество привитого слоя, поверхностная плотность привитых групп, толщина слоя этилацетоацетата меди на поверхности силикагеля.
Процессы адсорбции органических соединений (н-алканов, галогензамещенных алканов, 1-нитропропана, гептена-1, ароматических углеводородов, кетонов и спиртов), способных к различным типам межмолекулярных взаимодействий с Силохромом С-120 и сорбентом на его основе исследованы газохроматографически. Модифицирование SiO2 этилацетоацетатом меди приводит к выраженному повышению констант Генри адсорбции спиртов, кетонов и ароматических углеводородов, обусловленному проявлением донорно-акцепторных, ориентационных и π-взаимодействий адсорбат-адсорбент. Рассчитанные термодинамические характеристики (q̅dif,1 и) указывают на повышение адсорбционного потенциала нового сорбента, отражающееся в возрастании теплот и энтропии адсорбции тестовых соединений. На основе экспериментальных данных определено, что химическое модифицирование SiO2 медьацетоуксусным эфиром приводит к увеличению вклада специфических взаимодействий в теплоту адсорбции, при этом наибольшие значения Δq̅dif,1(спец) характерны для органических соединений, склонных к образованию водородных связей и донорно-акцепторному комплексообразованию. Анализ компенсационных термодинамических зависимостей показал, что определяющим термодинамическим параметром при адсорбции органических соединений на исследуемых сорбентах является энтропия. Полученный сорбент апробирован для разделения смесей органических соединений различных классов, в числе которых предельные и непредельные углеводороды, спирты, альдегиды и кетоны.
Продолжение обсуждения статьи В.А. Шапошника «Электростатическая теория селективности ионообменников»
Authors: Хамизов Руслан Хажсетович 
Published: December 2021

Дискуссионная статья Р.Х. Хамизова посвящена обсуждению материалов, представленных профессором В.А. Шапошником в журнале «Сорбционные и хроматографические процессы» (2021, Т. 21, № 1) В статье Р.Х. Хамизова и А.М.Долгоносова «К вопросу о статье В.А. Шапошника «Электростатическая теория селективных ионообменников» рассмотрены подходы к этой проблеме, в том числе, в модели Дж. Поли для оценки констант равновесия ионного обмена.
Более корректной моделью селективности представляется модель Дж. Эйзенмана, хотя она выступает только в роли качественной характеристики. Привлекательность модели Эйзенмана вытекает из того, что она неподгоночная. Эйзенман использовал в своих расчетах табличные значения кристаллохимических радиусов, считая, что между фиксированным ионом и противоионом нет молекул воды.
Критические замечания в адрес В.А. Шапошника в своем подходе к теории селективности сделаны в связи с тем, что, развивая какую-то гипотезу, необходимо пользоваться не только первыми шагами предшественников, но и последующими (или наиболее признаваемыми) достижениями. В этом плане выражено несогласие с позицией В.А. Шапошника в том, что он отказывается от энергии дегидратации. Неучет энергий дегидратации при рассмотрении селективности ионообменников приводит к очень большим ошибкам. Следует отметить, что модель качественную, основанную на энергии кулоновского взаимодействия, до количественных оценок успешно довел Д. Райхенберг, введя в соответствующие соотношения термы для энергий близкодействующих взаимодействий, включая дисперсионные.
Автор данной статьи считает, что поправлять расчеты с помощью дробных зарядов в точечной модели Кулона (где не предусмотрена делокализация) нецелесообразно. Рассматривая применимость уравнения Пуассона к ионообменникам, автор этой статьи рекомендует ознакомиться с его работами (в соавторстве с Н.А. Тихоновым), где были решены очень сложные задачи для сильноосновных анионообменников и гидрогелей на основе графена.

Published: December 2021

One of the most pressing issues in modern tax law is the solution of the issue of taxation in the field of electronic commerce. Currently, in the world practice of national states and economic unions of taxation, a number of methods have been formed related to the development of a tax mechanism in this area.An analysis of the scientific literature, as well as domestic and international legislation, indicates that attempts are being made to legally regulate the term “electronic commerce”, as well as to determine the types of taxes applicable to it. The most common taxes in international tax practice are VAT and the tax on goods and services. The Russian Federation also uses VAT in this area in the implementation of electronic commerce.

Published: December 2021

This study discusses electronic business licensing in Indonesia, by reviewing and analyzing the development of the regulations on electronic business licensing, electronically integrated business licensing reguations, and electronically integrated business licensing implementation. This research was conducted using normative legal research methods, with primary legal materials, secondary legal materials, and tertiary legal materials. The results of the study indicate that the development of regulations on business licensing is inseparable from the development of one-stop integrated licensing. However, the Online Single Submission system has not been implemented in all business licensing, leaving some with the use of offline arrangement. Proper implementation of electronic business licensing at the central government level, the provincial government level, to the regency level has not been achieved.
The Influence of the COVID-19 Pandemic on the U.S. Theater Industry
Authors: Khalilov Vladimir 
Published: December 2021

The article focuses on the effects, responses and consequences of the coronavirus pandemic on the U.S. theater industry. The author considers the economic contribution of the industry to the U.S. economy in the pre-covid years, restores the chronology of the shutdown (the longest closing of Broadway in history), lists the damages incurred, analyzes the measures taken, including at the federal level, to survive, and predicts the prospects for its development in the conditions of &quot;new normality&quot; and &quot;New Deal&quot; (on equality, diversity, inclusiveness and belonging).
The main negative consequences of a year and a half of industrial downtime are the sharp decrease in tourist flow and the shortfall of billions of dollars in trade both for the theatre and related industries (hotels, restaurants, transportation and other business sectors), as well as the growth of budget deficits, losses of direct and induced jobs and reduced incomes.
As practice shows, it will take at least 4-5 years for the industry in order to achieve the level and indicators of 2019, even with a complete return to normal life. Nevertheless, the author concludes that despite the temporary financial losses suffered by the theater industry, it demonstrates all the capacities for recovery, simultaneously mastering new artistic techniques and innovative ways to convey its products to the audience, as well as to systemic restructuring and transformation.

Published: December 2021

The success of a teaching process cannot be separated from the learning tools used, one of the requirements is that the learning tools must be valid. The success of a teaching process is measured by the extent to which students can master the subject matter presented by the teacher. A learning model is needed that can make it easier to develop critical thinking skills so that a truly valid learning tool is obtained to measure the potential and skills that exist in students. Among the learning models that emphasize the process of seeking and finding is the inquiry model. This study aims to prepare in measuring critical thinking skills of Madrasah Tsanawiyah students. The Learning Toolkit has been validated by 3 experts and will then be averaged to find the final score. The values obtained will be entered into the validation criteria table based on the validation criteria table and the results are that the tools made are very valid and can be used in the teaching and learning process because previously the tools made have been revised several times. Keywords: validity, learning tools, critical thinking skills AbstrakKeberhasilan suatu proses pengajaran tidak terlepas dari perangkat pembelajaran yang digunakan, salah satu persyaratan adalah perangkat pembelajaran harus valid.
