Localized Ionic Reinforcement of Double Network Granular Hydrogels

Nature produces soft materials with fascinating combinations of mechanical properties. For example, the mussel byssus embodies a combination of stiffness and toughness, a feature that is unmatched by synthetic hydrogels. Key to enabling these excellent mec ...

Nanolithography of the nanocorral structure of chemisorbed oxygen atoms on the graphitic lattice

Kumar Varoon Agrawal, Shaoxian Li

Controlled atomic patterning is an attractive tool to fine tune properties of graphitic lattice. Several O-functionalized derivatives of graphitic lattice have been widely studied, e.g., graphene oxide, reduced graphene oxide, and functionalized carbon nan ...

Colloidal-ALD Grown Hybrid Shells Nucleate via a Ligand–Precursor Complex

David Lyndon Emsley, Raffaella Buonsanti, Anna Loiudice, Kevin Rossi, Michael Allan Hope, Snaedis Björgvinsdóttir, Ona Segura Lecina, Amrit Venkatesh

Colloidal atomic layer deposition (c-ALD) enables the growth of hybrid organic/inorganic oxide shells with tunable thickness at the nanometer scale around ligand-functionalized inorganic nanoparticles (NPs). This recently developed method has demonstrated ...

Wetting of nanopores probed with pressure

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion, Michal Daniel Macha, Sebastian James Davis

Nanopores are both a tool to study single-molecule biophysics and nanoscale ion transport, but also a promising material for desalination or osmotic power generation. Understanding the physics underlying ion transport through nano-sized pores allows better ...

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 ...

Single yeast cell nanomotions correlate with cellular activity

Giovanni Dietler, Sandor Kasas, María Inés Villalba, Anton Malovichko

Living single yeast cells show a specific cellular motion at the nanometer scale with a magnitude that is proportional to the cellular activity of the cell. We characterized this cellular nanomotion pattern of nonattached single yeast cells using classical ...

Three-dimensional imaging of integrated circuits with macro- to nanoscale zoom

Gabriel Aeppli, Manuel Guizar Sicairos, Christian David, Michal Odstrcil

The imaging of integrated circuits across different length scales is required for failure analysis, design validation and quality control. At present, such inspection is accomplished using a hierarchy of different probes, from optical microscopy on the mil ...

The interfacial structure of nano-and micron-sized oil and water droplets stabilized with SDS and Span80

Sylvie Roke, Esther Amstad, Nikolay Smolentsev, Evangelia Zdrali, Gianluca Nicolas Etienne

In this work, we provide a comparison between the stability and the interfacial structure of micrometer-sized and nanometer-sized droplets by employing a multi-instrumental approach comprised of the surface-sensitive technique of sum frequency scattering a ...

Automated Integration of Dual-Edge Clocking for Low-Power Operation in Nanometer Nodes

Andreas Peter Burg, Adam Shmuel Teman, Andrea Bonetti, Nicholas Alexander Preyss

Clocking power, including both clock distribution and registers, has long been one of the primary factors in the total power consumption of many digital systems. One straightforward approach to reduce this power consumption is to apply dual-edge-triggered ...

Nanoscale studies link amyloid maturity with polyglutamine diseases onset

Giovanni Dietler, Hilal Lashuel, Giovanni Longo, Francesco Simone Ruggeri, Urszula Beata Cendrowska

The presence of expanded poly-glutamine (polyQ) repeats in proteins is directly linked to the pathogenesis of several neurodegenerative diseases, including Huntington's disease. However, the molecular and structural basis underlying the increased toxicity ...
