Protonolysis of a Ruthenium–Carbene Bond and Applications in Olefin Metathesis [PDF]

open access: yes, 2011
The synthesis of a ruthenium complex containing an N-heterocylic carbene (NHC) and a mesoionic carbene (MIC) is described wherein addition of a Brønsted acid results in protonolysis of the Ru–MIC bond to generate an extremely active metathesis catalyst ...

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

open access: yesAdvanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

open access: yesAdvanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Synthesis, Characterization, Electrochemistry, and Spectroscopic Properties of Some Anthracenyl Functionalized Phthalocyanine Complexes of Ruthenium(II)

open access: yesJournal of Chemistry, 2014
The synthesis of single- and double-decked anthracenyl functionalized ruthenium(II) phthalocyanine complexes has been achieved through a controlled electrophilic aromatic substitution reaction of the free unsubstituted ruthenium(II) phthalocyanine with ...

Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

open access: yesAdvanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Shaping Carbon Nitrides for Advanced Macrostructures

open access: yesAdvanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design
