Cubic boronate ester cages with unprecedented robustness and stability under ambient conditions were synthesized using a dynamic covalent approach. Sterically demanding t-Bu groups were installed in ortho-positions of diboronic acid precursor 4, which kinetically suppressed exchange of oxygen substituents under neutral conditions but allowed catalysis in acidic media. These cages can dissolve in protic solvents like MeOH and tolerate slightly acidic conditions without degradation. Crystalline samples of 6a remained structurally intact and retained microporous solid-state arrangement even after prolonged storage in MeOH or H2O. The cages demonstrated potential for adsorption of β-carotene and on-demand release under strong acidic stimulus, and encapsulation of a molecular Ru catalyst for photocatalytic water oxidation with enhanced kinetics and stability.

The article presents a study on the size determination of covalent organic cages using diffusion-ordered NMR spectroscopy (DOSY). It discusses the challenges in characterizing complex cage structures and how DOSY NMR can be a powerful tool to distinguish cages by size in solution. The study provides a guideline for determining diffusion coefficients from 1H-DOSY NMR spectra and elaborates on the influence of solvent, guest encapsulation, and exohedral substituents on diffusion behavior. The research includes comprehensive measurements on various cage compounds, analyzing the correlation between diffusion and molecular mass for different cage topologies and extending investigations to various covalent organic cages from the literature.

The study explores the synthesis of molecular nanocubes through co-condensation processes and the effects of varying alkyl substituents on solubility and precipitation. The research details the self-assembly of novel cubic cages, their characterization, and the analysis of their solubility, mobility, and structural integrity. The study also discusses the challenges in obtaining single crystals suitable for X-ray diffraction and the successful crystallization of cages in a trigonal space group. The findings reveal the isoreticular packing within the series of cages and the potential of these cages for selective gas sorption and the design of porous materials.

The study analyzes the use of Ellenberg indicator values in ecological research from 2020 to 2022, focusing on habitat assessment and vegetation dynamics. It reveals that most studies were conducted in Germany and Poland, with forests and grasslands being the primary focus. The research confirms the effectiveness of Ellenberg indicator values in addressing ecological niches, habitat analysis, and the impact of various factors on plants. The study also highlights the importance of adapting these values for new regions and improving ecosystem assessment methodologies. Despite recent publication, the articles are actively cited, indicating the relevance and scientific significance of the research.

Artificial intelligence (AI) encompasses various methods and disciplines such as vision, perception, speech, decision making, and robotics, with applications in construction to enhance safety and efficiency. The study reviews scientific publications on AI in construction, highlighting the use of 3D modeling, machine learning, computer vision, and unmanned aircraft systems. AI technologies are shown to improve construction management, safety, and productivity, addressing issues like low labor productivity and high accident rates. The research emphasizes the need for digitalization in the construction industry to optimize resources and ensure sustainable development. The study also discusses the historical development of AI in construction, the role of AI in ensuring safety, cost estimation, contract management, and logistics, and the prospects and limitations of AI in the industry.

The article examines the current state of solid waste management systems in developed and developing countries, with a focus on the features and prospects of waste management in Russia. It identifies the organizational, sanitary, and legal measures in place, and the legal regulation of relations and law enforcement practices in the field of solid municipal waste management. The text highlights the positive experiences of countries implementing sustainable systems of safe waste management and discusses the positions of judicial bodies on controversial issues of waste management in cities. The study aims to provide a basis for an environmental policy of safe waste management at all levels of public authority and to improve legislation in the field of waste management.

The study explores the potential of using microalgae, specifically Arthrospira platensis and Chlorella vulgaris, as ingredients in functional bread production. The research involved baking bread with varying concentrations of microalgae and analyzing its organoleptic, physicochemical, and antioxidant properties. Findings indicate that bread with 3% microalgae content had the best balance of texture, taste, and nutritional value, including increased polyphenol content and antioxidant capacity. The study concludes that microalgae-enriched bread could offer improved nutritional and biological value, making it a competitive alternative to traditional wheat bread.

The article explores the complexity of neuronal circuits in the central nervous system, focusing on the habenuloid complex and its potential as a biomarker for psychiatric disorders. It discusses the evolutionary development of the forebrain and the dorsal diencephalic connection system, emphasizing the role of genetic variants of receptors, transporters, or enzymes in predicting treatment responses. The most promising biomarkers are linked to the activation or inhibition of the nicotine receptor, dopamine D4 receptor, μ-opioid receptor, and the functioning of habenular glia cells. The article calls for more nuanced research into the habenula's role in mental disorders and the development of specific biomarkers.

Russian student Darya, a survivor of domestic violence, is advocating for stronger protections for women in Russia. After being shot by her boyfriend, she has become a vocal critic of the country's inadequate laws and cultural attitudes towards domestic violence. Despite her traumatic experience, Darya is rebuilding her life, using her platform to raise awareness and support other victims. The article highlights the broader issue of violence against women in Russia and the need for legislative reform.

Tensions in Kiev escalated as protesters from Spilna Sprava seized the Justice Ministry building, leading to threats of a state of emergency by Justice Minister Olena Lukash. The protests, demanding President Viktor Yanukovych's resignation, have spread, with Lukash warning that negotiations could be halted if the building is not vacated.
