A fundamental unsolved problem is to understand the differences between inanimate matter and living matter. Although this question might be framed as philosophical, there are many fundamental and practical reasons to pursue the development of synthetic materials with the properties of living ones. There are three fundamental properties of living materials that we seek to reproduce: The ability ...

We present a novel method to produce a PMMA-quantum-dot (QD) composite fabricated by pre-polymerization of PMMA and dispersing commercially available colloidal semiconductor QDs. The QDs are stabilized in rapidly formed oligomer matrices, and the complete polymerization of the PMMA-QD composite is achieved by commonly used polymerization. The properties of the PMMA-QD composite are measured and...

A solution-phase halide passivation strategy to engineer the optical properties of two-dimensional transition metal dichalcogenides synthesized by a colloidal approach.

Colloidal particles interacting via a long-range repulsion can, in contrast to hard-sphere systems, exhibit crystalline ordering at low volume fraction. Here we experimentally investigate the structure and properties of such "colloidal Wigner crystals." We find a body-centered-cubic crystalline phase at volume fractions of ϕ≳15%, which exhibits large fluctuations of individual particles from th...

A review is given of liquid crystals formed in colloidal dispersions, in particular those consisting of mineral particles. Starting with the historical development and early theory, the characteristic properties related to the colloidal nature of this type of liquid crystals are discussed. The possibility to find biaxial nematic and smectic phases is described for mixtures of rods and plates an...

A dual thermoresponsive and magnetic colloidal gel matrix is described for enhanced stem-cell culture. The combined properties of the material allow enzyme-free passaging and expansion of mesenchymal stem cells, as well as isolation of cells postculture by the simple process of lowering the temperature and applying an external magnetic field. The colloidal gel can be reconfigured with thermal a...

Poly(methyl methacrylate) (PMMA) stabilized colloidal metallic iron nanoparticles without additional surfactant or stabilizer were fabricated by a wet chemical reduction method. The synthesized colloidal iron nanoparticles were found to be stable in tetrahydrofuran (THF) solution and the dried PMMA–Fe nanocomposites were ferromagnetic even at room temperature as illustrated by magnetometer meas...

Solid lipid nanoparticles (SLN) have been reported to be an alternative system to emulsions, liposomes, microparticles and their polymeric counterparts for various application routes since the early 1990s due to their advantages. Solid lipid nanoparticles colloidal drug carrier system gained a lot of popularity among researcher as colloidal drug carriers for incorporating hydrophilic or lipophi...

smp was substituted by wpc in four levels for preparing reconstituted milk. two ropy and one nonropy starter cultures was used for doogh preparation. yield stress, viscosity, consistency index and pseudoplastic behavior of doogh increased by increasing wpc content. results showed that wpc increased colloidal particles dimension and constructed a network which led to a decrease in doogh phase se...

Colloidal Self Assembly In article number 2211197, Dwaipayan Chakrabarti and co-workers report on the self-assembly of enantiomorphic single colloidal gyroid crystals in silico from designer chiral patchy spheres. Each these is shown to support a complete photonic bandgap, whilst also exhibiting rich chiroptical properties. This computational study introduces gyroids as attractive targets for o...
