Cyclic and Macrocyclic Organic Compounds - a Personal Review in Honor of Professor Leopold Ružička [PDF]
Kemija u Industriji, 2009 Ružička opened the field of cyclic molecules such as cyclic terpenes and cyclic ketones with up to 17 ring atoms. This work until now was extended in many directions such as cyclic paraffins, crown ethers and cryptands and cyclic ester amides.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies
Advanced Functional Materials, EarlyView.Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Advanced Functional Materials, EarlyView.The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption
Advanced Functional Materials, EarlyView.Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Stereoselective alkene syntheses from cyclic enol ethers
, 1988 Two novel methods for the stereoselective synthesis of trisubstituted olefins from cyclic enol ethers were investigated. The first utilised the nickel (O)-catalysed coupling reactions of α-alkyl substituted cyclic enol ethers with Grignard reagents.

Journal of the American Chemical Society, 2020 Ruthenium alkoxymethylidene complexes have rarely been demonstrated as active species in metathesis reactions and are frequently regarded as inert. Herein, we highlight the ability of these Fischer-type carbenes to participate in cascade alternating ring-

Advanced Functional Materials, EarlyView.A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...
