Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Dithioketal Polymers Via Radical Polymerization of γ‐Dithiobutyrolactone
Angewandte Chemie, EarlyView.γ‐Dithiobutyrolactone (DTBL) behaves like a ring‐retaining monomer in radical copolymerization with a series of conjugated monomers like styrene, t‐butyl acrylate and N,N‐dimethylacrylamide. The resulting copolymers contain controlled fractions of dithioketal linkages in their backbone, allowing chemical degradation.

Pulling and Stretching a Molecular Wire to Tune its Conductance
, 2015 A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured during the lifting procedure are associated to the detachment of molecular

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing
Advanced Functional Materials, EarlyView.A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Proximity‐Induced Transfer of a Mass Tag Enables Direct Profiling of Active Matrix Metalloproteases
Angewandte Chemie, EarlyView.A proximity‐induced, mass‐encoded activity‐based protein profiling (ABPP) approach transfers a MALDI‐detectable α‐cyano‐4‐hydroxycinnamic acid (CHCA) tag directly to active proteases. This tag enables the direct, multiplexed, and quantitative detection of enzyme activity in complex proteomes without enrichment or purification.

Methodos, 2005 According to the most part of historians, the reception of Bacon’s natural philosophy shows its failure to restore sciences. Bacon was not read faithfully, because his natural philosophy did not grasp with the new science’s canons.

Advanced Functional Materials, EarlyView.Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Cobalt‐Catalyzed Intramolecular C─H Silylation of Arenes
Angewandte Chemie, EarlyView.Direct C─Si bond formation via C─H silylation is an atom‐economical route to organosilanes but is largely limited to noble metals. We report the first cobalt‐catalyzed intramolecular arene C–H silylation enabled by HCo(PMe3)4, which activates Si–H and C–H bonds to form diverse silacycles and silafluorenes in high yields with broad functional‐group ...
