In an effort to contribute to research in scalable production systems for polymeric delivery systems loaded with antimicrobial peptides (AMPs), we here investigate effects of hydrodynamic flow conditions on microfluidic particle generation. For this purpose, rapid prototyping using 3D printing was applied to prepare micromixers with three different geometric designs, which were used to prepare Ca-cross-linked alginate microgels loaded with the AMP polymyxin B in a continuous process. Based on fluid dynamic simulations, the hydrodynamic flow patterns in the micromixers were designed to be either (i) turbulent with chaotic disruption, (ii) laminar with convective mixing, or (iii) convective with microvortex formation.

Hypothesis: Temperature-controlled self-faceting of liquid droplets has been recently discovered in surfactant-stabilized alkane-in-water emulsions. We hypothesize that similar self-faceting may occur in emulsion droplets of UV-polymerizable linear hydrocarbons. We further hypothesize that the faceted droplet shapes can be fixed by UV-initiated polymerization, thus providing a new route towards the production of solid polyhedra. Read More

Biodegradable polymer based 'controlled release packaging' technology has ability to release packaging actives in controlled manner to prolong the food shelf-life. Currently available systems are not sufficiently capable of releasing multiple actives in sustainable fashion. Hence, the purpose of this study was to develop dual actives (antioxidant and antibacterial) loaded multilayered microparticles in one step and to release them at rates suitable for long-term inhibition of bacterial growth as well as lipid oxidation in food.

The carbon quantum dots termined with amine groups (CQDs-NH) were synthesized in one-pot hydrothermal method with citric acid as carbon source and branched polyethylenimine (BPEI) as passive agent, which was then covalently linked to 1, 4, 7, 10-tetraazacyclononane (DOTA) framework to yield CQDs-DOTA. The CQDs-DOTA provide excellent ligand scaffolds for the chelation of lanthanide ions, yielding the related complexes CQDs-DOTA-Ln (Ln = Eu, Tb, Yb and Gd). The successful preparation of CQDs-DOTA-Ln was validated by TEM, XRD, XPS, and FT-IR spectroscopy. Read More

Using video microscopy and particle-tracking techniques developed for dense Brownian systems of polygons, we study the structure-dynamics relationship in a near-equilibrium 2D glass consisting of anisotropic Penrose kite-shaped colloids. Detailed vibrational properties of kite glasses, both translational and rotational, are obtained using covariance matrix techniques. Different from other colloidal glasses of spheres and ellipsoids, the vibrational modes of kite glasses at low frequencies show a strong translational character with spatially localized rotational modes and extended translational modes.

How to reduce the usage of precious metals in electrocatalysts is a big challenge for the development of fuel cells. Metal nanoclusters (NCs) are highly desirable as active catalysts, but palladium nanoclusters (Pd NCs) have been less well developed than other metal clusters, such as gold, silver and copper, owing partly to the difficulties in size-controlled synthesis. Here, based on N, N-dimethylformamide (DMF)-mediation and ligand-exchange reaction, atomically precise Pd(CHS) nanoclusters are successfully synthesized. Read More

The self-assembly of AB diblock copolymers in three-dimensional (3D) soft confinement of nanoemulsions has recently become an attractive bottom up route to prepare colloids with controlled inner morphologies. In that regard, ABC triblock terpolymers show a more complex morphological behavior and could thus give access to extensive libraries of multicompartment microparticles. However, knowledge about their self-assembly in confinement is very limited thus far. Read More

Pyrrole, furan, and thiophene modified hyper-cross-linked polymers (HCPs) were prepared in one-pot method by two successive Friedel-Crafts reactions, and they were assessed by phenol adsorption from aqueous solution. The results indicated that the three chemically modified polymers had lower Brunauer-Emmett-Teller surface area and pore volume than the common HCPs, while the phenol adsorption on the pyrrole and thiophene modified polymers was relatively enhanced due to the introduction of the heteroatoms on the surface. Notably, the enthalpy changes of HCP-Py, HCP-Fu, and HCP-Th were greater than the HCPs, and the introduced heteroatoms provide greater interaction with phenol through dipole-dipole interaction.

A novel polymer-coated ZnO based bilayer electron transporting material is investigated for highly efficiency perovskite solar cells. The bilayer ETM consisting of an upper-layer of ZnO nanosheets and a lower-layer of ZnO nanoparticles demonstrates the averaged power conversion efficiency of 13.11% and a maximum power conversion efficiency of 15.

Capacitive deionization (CDI), which is one of up-and-coming water treatment technologies, is based on ion electrostatic adsorption on electrode surface. Herein, three-dimensional channel-structured graphene (CSG), which was synthesized via exothermic reaction between liquid potassium and carbon monoxide gas, was demonstrated as an efficient electrode material for CDI. Namely, the CSG electrode exhibited a specific capacity of 207. Read More
