Alkoxide complexes of rhenium, niobium and tantalum [PDF]

open access: yes, 2009
This thesis describes two major methods for preparation of new mono-, bi- and trimetallic complexes on the basis of Rhenium, Niobium and Tantalum: (1) - the electrochemical method for the synthesis of Re4O4(OEt)12 and (2) - the interaction of Rhenium ...

Recycling of Polymer Components From Waste Face Masks for Asphalt Modification: A Mini Review

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The COVID‐19 pandemic greatly increased plastic waste through widespread personal protective equipment (PPE) use, creating a serious environmental challenge. Disposable face masks (FM), primarily composed of non‐biodegradable polypropylene, account for an estimated 86 million units discarded monthly, leading to significant environmental ...

Poly(aryl ethers) and related polysiloxane copolymer molecular coatings: Preparation and radiation degradation [PDF]

open access: yes
The radiation degradation of poly(arylene ether sulfones) and related materials is studied. These basic studies are important both as a means to developing stronger, more stable matrix resins for composite materials, as well as to improve the data base ...

A Practical Guide to Heterogeneous Catalysis in Hydrocarbon Transformations

open access: yesChemistry – An Asian Journal, EarlyView.
A focused overview of the catalytic processing of hydrocarbons to transform them into more valuable compounds is presented. This work is intended to assist BSc, MSc, and PhD students, as well as junior researchers, in selecting and performing appropriate heterogeneous catalytic processes for specific heterogeneous catalytic reactions.

Boron: A key element in radical reactions [PDF]

open access: yes, 2017
Boron derivatives are becoming key reagents in radical chemistry. Here, we describe reactions where an organoboron derivative is used as a radical initiator, a chain-transfer reagent, and a radical precursor.

Catalytic Reactions Involving the Oxidative Addition of Si─Halogen and Si─Pseudohalogen Bonds as a Key Step

open access: yesChemistry – An Asian Journal, EarlyView.
This review highlights the transition metal‐catalyzed reactions in which the oxidative addition of R3Si‐X (I, Br, Cl, F, and OTf) appears to be a key step. The reaction of C─C multiple bonds, such as alkenes, alkynes, and 1,3‐dienes with R3Si‐X proceeds though silylmetalation.

Comparative Study of High Voltage Spinel∥Lithium Titanate Lithium‐ion Batteries in Ethylene Carbonate Free Electrolytes

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
FEC and sulfone‐based co‐solvents are investigated as EC‐free electrolytes for LNMO∥LTO cells. FEC‐containing electrolytes demonstrate enhanced electrochemical stability by stabilizing the CEI and SEI layers, mitigating transition metal migration. Conversely, sulfone electrolytes form thinner CEIs and thick, sulfur‐rich SEIs, which are less effective ...

Structure–Performance Relationships in Anthraquinone‐Disulfonate Coordination Polymers for Li‐Ion and Na‐Ion Battery Cathodes

open access: yesBatteries &Supercaps, EarlyView.
Anthraquinone‐disulfonate coordination polymers (AQDS‐Na, AQDS‐Mg, AQDS‐Cu) are synthesized and evaluated as cathodes for Li‐ion and Na‐ion storage. Structural dimensionality and coordinated water critically impact the practical capacity and cycling stability, highlighting design principles for organic‐based energy storage materials.
