Eco-compatible oxides enabling energy storage via Li+/Mg2+ co-intercalation

10 Oct 2024  |  pubs.rsc.org
The article explores a novel approach to enhance magnesium ion intercalation in energy storage systems by utilizing dual intercalation of lithium and magnesium ions. This method leverages eco-compatible oxides like magnesium manganate spinels and lithium titanates, which exhibit varying potentials of ion intercalation. The study demonstrates the synthesis of well-crystallized nanosized spinels and examines their intercalation properties in model cells. A new hybrid Li–Mg ion cell is developed, achieving an operating voltage of approximately 1.7 V, showcasing the potential for improved energy density in lithium-ion batteries.

Epimerization of glucose over ionic liquid/phosphomolybdate hybrids: structure–activity relationship

17 Aug 2024  |  pubs.rsc.org
The article discusses the epimerization of glucose using ionic liquid/phosphomolybdate hybrids, focusing on the structure–activity relationship. It provides detailed insights into the chemical processes and the efficiency of the catalysts used.

A Water-Stable Boronate Ester Cage

13 May 2024  |  pubs.acs.org
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.

Size Determination of Organic Cages by Diffusion NMR Spectroscopy

15 Apr 2024  |  chemistry-europe.onlinelibrary.wiley.com
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.

Isoreticular Crystallization of Highly Porous Cubic Covalent Organic Cage Compounds

13 Apr 2024  |  onlinelibrary.wiley.com
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.

Practical Batch Proofs of Exponentiation

01 Jan 2024  |  IACR Cryptology ePrint Archive
Introduces two new batch Proofs of Exponentiation (PoEs) that outperform previous proposals by Rotem, combining them to improve efficiency and adapting the bucket test from Bellare, Garay, and Rabin for groups of unknown order. These new PoEs significantly reduce proof size and verification complexity, achieving substantial improvements even with non-optimized implementations, and provide a tight reduction under the low order assumption for secure batching.

Global Overview of Modern Research Based on Ellenberg Indicator Values

21 Dec 2023  |  MDPI
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.

Bulletproof: a survivor fights to end violence against women in Russia

25 Nov 2023  |  Yahoo Entertainment
Darya, a Russian student, survived a violent attack by her boyfriend and is now advocating for stronger protections against domestic violence in Russia. Despite the challenges she faced, including a severe injury, she is determined to use her experiences to help others. The article highlights the inadequacies in Russian laws regarding domestic violence, with criticism directed at President Vladimir Putin for easing penalties. Organizations like the United Nations and the Centre for the Protection of Victims of Domestic Violence are mentioned in the context of global and local efforts to combat violence against women.

Artificial Intelligence Methods for the Construction and Management of Buildings

26 Oct 2023  |  MDPI
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.

Municipal and Industrial Urban Waste: Legal Aspects of Safe Management

25 May 2023  |  mdpi.com
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.
