Surface modified microfibrillated cellulose‐poly(vinylidene fluoride) composites: β‐phase formation, viscoelastic and dielectric performance

Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Mohammed Arif Poothanari

The effect of silylation of microfibrillated cellulose (MFC) surfaces on β‐phase formation in poly(vinylidene difluoride) (PVDF) and the resulting viscoelastic and dielectric performance of MFC‐PVDF composites is investigated. Two different organosilanes, ...

Self-consistent Hubbard parameters from density-functional perturbation theory in the ultrasoft and projector-augmented wave formulations

Nicola Marzari, Iurii Timrov, Matteo Cococcioni

The self-consistent evaluation of Hubbard parameters using linear-response theory is crucial for quantitatively predictive calculations based on Hubbard-corrected density-functional theory. Here, we extend a recently introduced approach based on density-fu ...

Crystallographically Oriented Hybrid Perovskites via Thermal Vacuum Codeposition

Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Yen-Cheng Liu, Cristina Roldán Carmona, Hiroyuki Kanda, Nadja Isabelle Desiree Klipfel, Cheng Liu, Maria Cristina Momblona Rincón

Hybrid lead halide perovskites typically form polycrystalline films that have multiple grain sizes and surface defects. A key engineering challenge toward commercialization is therefore the production of homogeneous, defect-free largearea devices achieving ...

Focusing on the liquid role in the vapour liquid solid growth mechanism

Lea Ghisalberti

In this work we dive into key questions regarding the wetting of a nanoscale droplet which provides fundamental understanding of Vapor-Liquid-Solid growth mode of nanowires. This understanding is important to performreproducible NW fabrication and allow th ...

Secondary ice production in summer clouds over the Antarctic coast: an underappreciated process in atmospheric models

Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Etienne Gabriel Henri Vignon

The correct representation of Antarctic clouds in atmospheric models is crucial for accurate projections of the future Antarctic climate. This is particularly true for summer clouds which play a critical role in the surface melting of the ice shelves in th ...

Reduction of PdO/Al2O3 in Liquid Cyclohexane Followed In Situ by ATR-IR, High-Energy XRD, and XAS

Oliver Kröcher, Davide Ferri, Thibault Xavier Florian Fovanna

Supported Pd-based catalysts used in heterogeneously catalyzed liquid phase processes often undergo an activation step through reduction of the oxide phase or of the oxidic passivation layer prior to reaction. An oxidized Pd/Al2O3 catalyst was reduced by u ...

Fabrication of micrometer-sized drops as templates for particles

Mathias Steinacher

Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...
