High-Performance Porous Supports Based on Hydroxyl-Terminated Polysulfone and CO/CO-Selective Composite Membranes.

The scope of this work was to develop a thin-film composite (TFC) membrane for the separation of CO/CO mixtures, which are relevant for many processes of gas processing and gasification of carbon-based feedstock. Special attention was given to the development of highly permeable porous polysulfone (PSF) supports (more than 26,000 GPU for CO) since both the selective and support layers contribute significantly to the overall performance of the TFC membrane. The PSF porous support is widely used in commercial and lab-scale TFC membranes, and its porous structure and other exploitation parameters are set during the non-solvent-induced phase separation (NIPS) process.

Investigation of the 4D Multi-Material 316L/FeNi36 Obtained by Selective Laser Melting.

Multi-material can have functional properties, which are not typical for the materials of which they are composed (for instance, shape-changing effect). This can be used in robotics, micromachines, aerospace, and other fields. In this work, the 316L/FeNi36 multi-material produced by selective laser melting was investigated.

Metabolic and Morphological Aspects of Adaptation of Alkaliphilic 5-DB and Alkali-Tolerant ATCC 6633 to Changes in pH and Mineralization.

The goal of the study is to evaluate metabolic and morphological changes of the facultative alkaliphile 5-DB and the weakly alkali-resistant ATCC 6633 in a wide pH range and at different NaCl concentrations. The alkaliphile 5-DB is shown to have a broader general resistance to adverse factors (wide pH range, 50 g/L NaCl) than a weakly alkali-tolerant strain of the same genus. This alkaliphile is also shown to have a significantly greater resistance not only to high pH but also to low pH in comparison with ATCC 6633.

[To assess Resilience of Russian cities under international sanctions and the consequences of COVID-19: a sociological study].

The paper presents the results of in-depth interviews and a questionnaire survey of the Russian cites administration representatives about cities resilience under the sanctions pressure and COVID-19. The survey was conducted by the Center for Territorial Changes and Urban Development of IPEI RANEPA in March-May 2023, it was attended by representatives of the administration of more than 50 cities of the Russian Federation. We found overall situation as stable: social programs are being implemented in full, unemployment is decreasing, construction of municipal facilities continues, problems with failures in the supply of spare parts, equipment and components are being solved.

Ecological and human health impact assessments based on long-term monitoring of soil PAHs near a coal-fired power plant.

The combustion of coal in power plants releases significant amounts of polycyclic aromatic hydrocarbons (PAHs), which are highly toxic and carcinogenic. This study assesses the ecological and human health impacts of PAHs contamination from a coal-fired power plant over 8 years. The monitoring site selection considered the distance from the power plant and the prevailing wind direction in the investigated area.
