Multifunctional Charge and Hydrogen-Bond Effects of Second-Sphere Imidazolium Pendants Promote Capture and Electrochemical Reduction of CO2 in Water Catalyzed by Iron Porphyrins

open access: yesAngewandte Chemie, 2022
Microenvironments tailored by multifunctional secondary coordination sphere groups can enhance catalytic performance at primary metal active sites in natural systems. Here, we capture this biological concept in synthetic systems by developing a family of

Catalytic One-Handed Helix Induction and Subsequent Static Memory of Poly(biphenylylacetylene)s Assisted by a Small Amount of Carboxy Groups Introduced at the Pendants

open access: yesACS Macro Letters, 2022
A dynamically racemic helical copolymer composed of an achiral biphenylylacetylene (BPA) bearing methoxymethoxy groups at the 2,2′-positions and 1 mol % of an achiral BPA carrying 2-carboxy-2′-methoxymethoxy groups at the biphenyl pendants was found to ...

Juglet Pendants from Pannonia [PDF]

open access: yes, 2020
Most juglet pendants are of 4th century from Pannonia, the glass is frequently dark, appearing black. Although juglet pendants have a greater concentration in the eastern Mediterranean, they are also widely attested in the empire’s western half.

Iterative synthesis of monodisperse pendants for making comb-like polyurethanes

open access: yes, 2018
Polyurethanes grafted with well-defined polar pendants were synthesized and investigated. A series of linear and dendritic poly(urea/malonamide)s with uniform chain length were first prepared from an iterative synthesis route, which is based on a dual ...

The naturally occurring radioactivity of ‘scalar energy’ pendants and concomitant radiation risk

open access: yesPLoS ONE, 2021
Forming part of a study of radiological risk arising from use of radioactive consumer products, investigation is made of pendants containing naturally occurring radioactive material. Based on use of gamma-ray spectrometry and Monte Carlo (MC) simulations,

Pendant capsule elastometry

open access: yesJournal of Colloid and Interface Science, 2018
We provide a C/C++ software for the shape analysis of deflated elastic capsules in a pendant capsule geometry, which is based on an elastic description of the capsule material as a quasi two-dimensional elastic membrane using shell theory. Pendant capsule elastometry provides a new in-situ and non-contact method for interfacial rheology of elastic ...
