Methane-to-chemicals: a pathway to decarbonization.

The utilization of methane for chemical production, often considered as the future of petrochemistry, historically could not compete economically with conventional processes due to higher investment costs. Achieving sustainability and decarbonization of the downstream industry by integration with a methane-to-chemicals process may provide an opportunity to unlock the future for these technologies. Gas-to-chemicals is an efficient tool to boost the decarbonization potential of renewable energy.

Exploration, explanation and exploitation of hydroxyls in zeolites.

The precise location and role of all types of hydroxyls in zeolites are still enigmatic, and their control permits tailoring of novel properties increasing the efficiency of catalysts and adsorbents in industrial processes for cleaner energy.

Laboratory markers of adaptation to Arctic conditions: scientific search and prospects of implementation.

The complex of climatic and geographical conditions of the Arctic determines the high intensity of the polysystem adaptive response of the organism, the duration of which is additionally influenced by individual genetic characteristics, social conditions, psychological and work loads. Taking into account the relevance of timely prevention and early diagnosis of stress-induced somatic pathology in EMERCOM employees working in unfavorable climatic and geographical zones, the authors evaluated the informative value of determining the level of steroid hormones and insulin as laboratory markers of adaptation to Arctic conditions. The expediency of developing objective criteria for the interpretation of the insulin/cortisol index and studying the informativeness of the 17ONprogesterone level as the earliest marker of adaptation to unfavorable climatic and geographical conditions of the Arctic is substantiated.

Unraveling the Effect of Silanol Defects on the Insertion of Single-Site Mo in the MFI Zeolite Framework.

The preparation of defect-free MFI crystals containing single-site framework Mo through a hydrothermal postsynthesis treatment is reported. The insertion of single Mo sites in the MFI zeolite samples with different crystal sizes of 100, 200, and 2000 nm presenting a diverse concentration of silanol groups is revealed. The nature of the silanols and their role in the incorporation of Mo into the zeolite structure are elucidated through an extensive spectroscopic characterization (Si NMR, H NMR, P NMR, and IR) combined with X-ray diffraction and HRTEM.

Unlocking the Potential of Hidden Sites in Faujasite: New Insights in a Proton Transfer Mechanism.

Zeolite Y and its ultra-stabilized hierarchical derivative (USY) are the most widely used zeolite-based heterogeneous catalysts in oil refining, petrochemisty, and other chemicals manufacturing. After almost 60 years of academic and industrial research, their resilience is unique as no other catalyst displaced them from key processes such as FCC and hydrocracking. The present study highlights the key difference leading to the exceptional catalytic performance of USY versus the parent zeolite Y in a multi-technique study combining advanced spectroscopies (IR and solid-state NMR) and molecular modeling.
