Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Nonperturbative Determination of Quark Masses in Quenched Lattice QCD with the Kogut-Susskind Fermion Action [PDF]

open access: yes, 1999
We report results of quark masses in quenched lattice QCD with the Kogut-Susskind fermion action, employing the regularization independent scheme of Martinelli et al.

Impact of PVDF Homo and Copolymer on Thiophosphate Solid Electrolyte Characteristics and Comprehensive Bulk‐To‐Surface Characterization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Na2Fe3(SO4)4: A Zero‐Strain Sustainable Positive Electrode Material for Na‐Ion Batteries

open access: yesAngewandte Chemie, Volume 137, Issue 44, October 27, 2025.
A new sustainable zero‐strain Na2Fe3(SO4)4 (NFS) positive electrode material is obtained by only ball‐milling from cheap and available Na2SO4 and FeSO4. Iron coordination polyhedra include the Fe2O11 dimer of distorted octahedra (active during cycling) and FeO5 trigonal bipyramid, similar to that in the relative Pbca‐Na2Mn3(SO4)4 (NMS).

DES modified silica gel as dispersing material for miniaturized matrix solid phase dispersion applied to triazoles determination

open access: yesAdvances in Sample Preparation
Matrix solid phase dispersion (MSPD) represents one of the most useful methods for pesticides determination in vegetables. This extraction method involves the use of a solid, dispersing material, which is homogenized together with the sample in a mortar ...

Pair distribution function studies in cementitious systems [PDF]

open access: yes, 2017
The analysis of amorphous/nanocrystalline phase(s) within cement matrices that contain high amounts of crystalline phase(s) is very challenging. Synchrotron techniques can be very useful to characterize such complex samples.1 This work is focused on ...

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

open access: yesFood Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Molecularly Imprinted Nanomicrospheres as Matrix Solid-Phase Dispersant Combined with Gas Chromatography for Determination of Four Phosphorothioate Pesticides in Carrot and Yacon

open access: yesJournal of Analytical Methods in Chemistry, 2015
An efficient, rapid, and selective method for sample pretreatment, namely, molecularly imprinted matrix solid-phase dispersion (MI-MSPD) coupled with gas chromatography (GC), was developed for the rapid isolation of four phosphorothioate organophosphorus
