Simultaneous determination of in situ vertical transitions of color, pore-water metals, and visualization of infaunal activity in marine sediments [PDF]

open access: yes, 2009
The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment profile imaging with diffusive gradient thin (DGT) gels

Paving the Way for Next‐Generation All‐Solid‐State Batteries: Dry Electrode Technology

open access: yesAdvanced Materials, EarlyView.
The dry‐electrode process offers a highly efficient solution to the key challenges faced by all‐solid‐state batteries, including complex processing, high CO2 emissions, interfacial instability, toxicity, and limited energy density. This perspective outlines the critical challenges of implementing the dry electrode process from material fundamentals to ...

Substrate-dependent divergent outcomes from catalytic reactions of silyl-protected enol diazoacetates with nitrile oxides: azabicyclo[3.1.0]hexanes or 5-arylaminofuran-2(3H)-ones.

open access: yesJournal of Organic Chemistry, 2012
Dirhodium(II)-catalyzed reactions of silyl-protected enol diazoacetates with nitrile oxides exhibit high nitrile oxide substituent dependence in the production rearrangement products via dipolar cycloaddition and either the Neber rearrangement or the ...

Carbazole‐Based Thin Microporous Polymer Films for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
Photocatalytic hydrogen evolution with electropolymerized microporous films enable a direct and scalable process for the production of industrial relevant amounts of hydrogen gas. For developing cost‐ and material‐effective devices it is beneficial to increase the accessible outer surface area via microstructuring and stacking of polymeric films ...

NMR studies on 1,3-dipolar cycloaddition of nitrile oxides to norbornenes

open access: yes, 2013
The 1,3-dipolar cycloaddition reaction of nitrile oxides to norbornenes substituted with an acrylate-derived moiety was examined. Only adducts to norbornene system were formed with a good exo selectivity and complete site-selectivity.

Reaction of pyrroles with ethyl 2-nitroso- and 2-azo-propenoates, and with ethyl cyanoformate N-oxide: a comparison of the reaction pathways [PDF]

open access: yes, 2012
The reaction of ethyl 2-nitrosopropenoate 2a with 1 -methylpyrrole, 2.5-dimethylpyrrole and 2.5- diphenylpyrrole has been investigated. In every case the products result from highly regioselective attack at C-2 of the pyrrole by the electrophile.

Interfacial Strength in Hierarchical Carbon Fiber Composites: Interplay of Interphase Modulus and Roughness

open access: yesAdvanced Materials Interfaces, EarlyView.
A facile deposition method involving two small molecule difunctional (DL) and trifunctional (TL) crosslinkers on a carbon fiber surface improves carbon fiber and acrylonitrile‐butadiene‐lignin rubber matrix adhesion and increases tensile strength by up to 50%.
