Miskoncepcie pojmov organickej chémie u absolventov základných škôl po školskej reforme na Slovensku

open access: yesScientia in Educatione, 2014
Početné výskumy dokazujú, že žiaci majú mylné predstavy v mnohých oblastiach chémie a problémy s pochopením viacerých chemických pojmov. Mylné koncepcie žiakov sú pevne zakotvené v ich kognitívnych štruktúrach, sú trváce, sú často odolné voči rôznorodým ...

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators

open access: yesAdvanced Science, EarlyView.
This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

Synergistic Optimization of Cathode Composite Architecture and Stack Pressure for High‐Performance All‐Solid‐State Chloride‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Composite cathode engineering and stack pressure co‐optimization enable a high‐performance all‐solid‐state chloride‐ion battery based on a VOCl/CsSn₀.₉In₀.₀₆₇Cl3/In architecture, delivering 169 mAh g−1 with 500‐cycle durability. Electrode‐resolved impedance tracking via distribution of relaxation times revealed progressive interphase and charge ...

Planar Chiral Carbazole‐Naphthalene Bisimide Hetero‐Cyclophane for Circularly Polarized Delayed Fluorescence

open access: yesAngewandte Chemie, EarlyView.
Tightly stacked carbazole and 1,2:5,6–naphthalene bisimide units afforded a planar chiral hetero‐cyclophane. The architecturally refined system, with strong charge‐transfer interaction and enhanced structural rigidity, exhibits orange‐red delayed CPL emission in both solution and solid states.

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

open access: yesAdvanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

Introducing Diradicaloid Thiele's Hydrocarbon Derivatives as Ligand in Transition Metal Chemistry

open access: yesAngewandte Chemie, EarlyView.
N‐doped Thiele's hydrocarbon derivative is introduced as a ligand for the synthesis of mono‐ and bimetallic rhodium complexes as well as cyclometalated iridium complexes. These compounds constitute the first metal complexes based on a Thiele's hydrocarbon (or p‐quinodimethane) derivative and, to the best of our knowledge, the first cyclometalated ...

Zähmung eines blauen Gases—Struktur und Chemie von Hexafluorthioaceton

open access: yesAngewandte Chemie, EarlyView.
Hexaflouorthioaceton (1), ein blaues Gas bei Raumtemperatur, wurde durch Vakuumpyrolyse des zyklischen Dimers bei 660 °C synthetisiert. Wir diskutieren grundlegende Eigeschaften des schwer greifbaren 1, einschließlich Einkristallstruktur und Kernmagnetische Resonansspektroskopie, obwohl es eine starke Tendenz zur Dimerisierung selbst bei –74 °C zeigt ...
