Experimental and theoretical evidence for molecular forces driving surface segregation in photonic colloidal assemblies
Surface segregation in binary colloidal mixtures offers a simple way to control both surface and bulk properties without affecting their bulk composition. Here, we combine experiments and coarse-grained molecular dynamics ...
Control of Stratification in Drying Particle Suspensions via Temperature Gradients
A potential strategy for controlling stratification in a drying suspension of bidisperse particles is studied using molecular dynamics simulations. When the suspension is maintained at a constant temperature during fast ...
A Geodetic Strain Rate and Tectonic Velocity Model for China
The conjoining and interfering influence of the Circum-Pacific zone and the Tethys-Himalayan zone make China a country of intense intracontinental seismicity. Here we provide three new quantitatively assessed products and ...
A New Family of High Tc Molecule-Based Magnetic Networks: V[x-ClnPTCE]2·yCH2Cl2 (PTCE = Phenyltricyanoethylene)
Using the structural and electronic tunability of molecules to control magnetism is a central challenge of inorganic chemistry. Herein, a ten-member family of the high-ordering temperature (<i>T</i><sub>c</sub>) molecule-based ...
Octametallic Cluster of Cp*Ir(glycinato) Cations
Block copolymer–based porous carbon fibers
(American Association for the Advancement of Science, 2019-02-01)
Carbon fibers have high surface areas and rich functionalities for interacting with ions, molecules, and particles. However, the control over their porosity remains challenging. Conventional syntheses rely on blending ...

Nematodes in a polar desert reveal the relative role of biotic interactions in the coexistence of soil animals
(Springer Nature, 2019-02-15)
Abiotic factors are major determinants of soil animal distributions and their dominant role is pronounced in extreme ecosystems, with biotic interactions seemingly playing a minor role. We modelled co-occurrence and ...
Environmental stresses induce karyotypic instability in colorectal cancer cells
Understanding how cells acquire genetic mutations is a fundamental biological question with implications for many different areas of biomedical research, ranging from tumor evolution to drug resistance. While karyotypic ...
Simulating demography, genetics, and spatially explicit processes to inform reintroduction of a threatened char
The success of species reintroductions can depend on a combination of environmental, demographic, and genetic factors. Although the importance of these factors in the success of reintroductions is well-accepted, they are ...
