Stability and cooperativity in chimeric de novo TIM barrels via quarter swapping. [PDF]

Protein Sci
Abstract The use of repetitive units as building blocks in protein design, mimicking evolutionary duplication events, is a valuable strategy that reduces structural complexity. Such modular designs offer an opportunity to dissect how local contributions are integrated in a context‐dependent manner.

Mechanochemical Synthesis of Lead-Free Halide Layered Double Perovskites: A Green and Scalable Approach. [PDF]

ChemSusChem
Herein we report a facile, green, and scalable synthetic alternative for the obtention of layered double perovskites (LDPs) via mechanosynthesis. This approach allows for the synthesis of phase‐pure LDPs in batches of up to 5 g within minutes. To our knowledge, this represents the largest scale and fastest synthesis of these materials reported to date.

Exploring the Antimicrobial Potential of Vanadium-Based MXenes for Biomedical Applications. [PDF]

Microbiologyopen
Vanadium‐based MXenes (V₂CTₓ and V₄C₃Tₓ) exhibit moderate antibacterial activity against E. coli and S. aureus, mainly through mechanical “nano‐knife” membrane disruption rather than ROS generation. These nanomaterials show good biocompatibility and highlight the importance of standardized experimental models for evaluating MXene antimicrobial ...

Mapping Functionally Relevant Tractable Lysines of Challenging Protein Targets by Covalent Fragment Screening. [PDF]

Chembiochem
Screening a lysine‐targeting covalent fragment library against challenging protein targets revealed suitable warheads and characterized binding sites for the development of targeted covalent ligands. Covalent fragment screening has become an established strategy for identifying targetable amino acid residues or viable chemical starting points against ...

Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer. [PDF]

Angew Chem Int Ed Engl
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

Efecto de las sales fundidas en la termofluencia del acero inoxidable tipo 304

Revista de Metalurgia, 1995
Los problemas causados tanto por la corrosión por sales fundidas, así como por la termofluencia en los tubos de los sobrecalentadores y recalentadores de una planta de potencia que usa combustibles fósiles, reducen su vida prevista en diseño.

Epigallocatechin 3-gallate inhibits the plasma membrane Ca2+-ATPase: effects on calcium homeostasis

Heliyon, 2021
Flavonoids are natural compounds responsible for the health benefits of green tea. Some of the flavonoids present in green tea are catechins, among which are: epigallocatechin, epicatechin-3-gallate, epicatechin, catechin and epigallocatechin-3-gallate ...

A Borane Sandwich Analogue of Ferrocene

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
The first ferrocene analogue with two boron‐based ligands is identified through a global exploration of the FeB10H20 potential energy surface. The η5,η5‐Fe(B5H10)2 complex emerges as the global minimum, showing that metal coordination inverts borane stability and enables aromatic boron rings inaccessible in isolation.

Comparative Study of the Effects of Aqueous Micellar Media Formed by Amphiphilic Ionic Liquids and Conventional Surfactants on Reactions of Synthetic Interest

Chemistry Proceedings, 2021
For polar Diels–Alder (DA) reactions, one of the most relevant aspects is its dependence on the reaction media; thus, in this work, the objective is to analyze the effect of aqueous micellar systems on the synthesis of compounds of biological interest ...
