Design and characterization of variable stiffness structural joints

This paper presents design and characterization of a new type of structural joint which can vary its stiffness through actuation. Stiffness variation is employed to control the dynamic response of frame structures equipped with such joints. The joint is ma ...

Rhodium(III)-Catalyzed Enantiotopic C-HActivation Enables Access to P-Chiral Cyclic Phosphinamides

Nicolai Cramer, Yang Sun

Compounds with stereogenic phosphorus atoms are frequently used as ligands for transition-metal as well as organocatalysts. A direct catalytic enantioselective method for the synthesis of P-chiral compounds from easily accessible diaryl phosphinamides is p ...

Elevated temperature, micro-compression transient plasticity tests. on nanocrystalline Palladium-Gold: Probing activation parameters at the lower limit of crystallinity

Stefano Mischler, Johann Michler, Xavier Maeder

In this study, we probe the activation parameters and time-dependent plastic behavior of a nano crystalline Palladium-Gold alloy by means of elevated temperature micropillar compression experiments. All tests were conducted on a stable, displacement-contro ...

Activated Dissociation of HCl on Au(111)

We report zero-coverage reaction probabilities (S-0) for HCl dissociative adsorption on Au(111) obtained by the seeded molecular beam hot-nozzle method. For measurements at normal incidence with mean translational energies ranging from 0.94 to 2.56 eV (noz ...

Reconstitution of [Fe]-hydrogenase using model complexes

Xile Hu, Matthew Wodrich, Tao Xu, Dafa Chen

[Fe]-Hydrogenase catalyses the reversible hydrogenation of a methenyltetrahydromethanopterin substrate, which is an intermediate step during the methanogenesis from CO2 and H-2. The active site contains an iron-guanylylpyridinol cofactor, in which Fe2+ is ...

CCN properties of organic aerosol collected below and within marine stratocumulus clouds near Monterey, California

Athanasios Nenes

The composition of aerosol from cloud droplets differs from that below cloud. Its implications for the Cloud Condensation Nuclei (CCN) activity are the focus of this study. Water-soluble organic matter from below cloud, and cloud droplet residuals off the ...

A Deeper Look at Dataset Bias

Barbara Caputo, Tatiana Tommasi, Novi Patricia

The presence of a bias in each image data collection has recently attracted a lot of attention in the computer vision community showing the limits in generalization of any learning method trained on a specific dataset. At the same time, with the rapid deve ...

Reactions of Grignard Reagents with Nitrous Oxide

Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov

The chemical activation of nitrous oxide (N2O) can be achieved by organocalcium, organosodium, and organolithium compounds. Grignard reagents, on the other hand, are believed to be inert. We demonstrate that this generalization is not correct. Some aliphat ...

Loading and release of internally self-assembled emulsions embedded in a magnetic hydrogel

László Forró, Andrzej Sienkiewicz, Katarzyna Pierzchala

We have investigated drug loading and release from thermosensitive gel emulsions with external triggering by an alternating magnetic field (AMF) for on-demand drug delivery. Superparamagnetic iron oxide nanoparticles dispersed in gel emulsions were used to ...

Incorporation of advanced aerosol activation treatments into CESM/CAM5: Model evaluation and impacts on aerosol indirect effects

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

One of the greatest sources of uncertainty in the science of anthropogenic climate change is from aerosol-cloud interactions. The activation of aerosols into cloud droplets is a direct microphysical linkage between aerosols and clouds; parameterizations of ...
