Estimation of p,p'-DDT degradation in soil by modeling and constraining hydrological and biogeochemical controls.

Environ Pollut 2018 Aug 11;239:179-188. Epub 2018 Apr 11.

Research Centre for Toxic Compounds in the Environment (RECETOX), Faculty of Science, Masaryk University, Kamenice 753/5, Brno, 62500, Czech Republic; Norwegian Institute for Water Research, Oslo, NO-0349, Norway. Electronic address:

Despite not being used for decades in most countries, DDT remains ubiquitous in soils due to its persistence and intense past usage. Because of this it is still a pollutant of high global concern. Assessing long term dissipation of DDT from this reservoir is fundamental to understand future environmental and human exposure. Read More

Directed Assembly of Janus Cylinders by Controlling the Solvent Polarity.

Langmuir 2017 08 21;33(30):7503-7511. Epub 2017 Jul 21.

Department of Chemical Engineering, Chungnam National University , 99 Daehak-ro, Yuseong-gu, Daejeon 34134, Republic of Korea.

This study demonstrates the possibility of controlling the directed self-assembly of microsized Janus cylinders by changing the solvent polarity of the assembly media. Experimental results are analyzed and theoretical calculations of the free energy of adhesion (ΔG) are performed to elucidate the underlying basic principles and investigate the effects of the solvent on the self-assembled structures. This approach will pave a predictive route for controlling the structures of assembly depending on the solvent polarity. Read More

Efficient Construction of Well-Defined Multicompartment Porous Systems in a Modular and Chemically Orthogonal Fashion.

Angew Chem Int Ed Engl 2017 03 6;56(14):3880-3885. Epub 2017 Mar 6.

Department of Chemistry, Key Lab of Organic Optoelectronics & Molecular Engineering, Tsinghua University, Beijing, 100084, China.

A microfluidic assembly approach was developed for efficiently producing hydrogel spheres with reactive multidomains that can be employed as an advantageous platform to create spherical porous networks in a facile manner with well-defined multicompartments and spatiotemporally controlled functions. This strategy allows for not only large scale fabrication of various robust hydrogel microspheres with controlled size and porosity, but also the domains embedded in hydrogel network could be introduced in a modular manner. Additionally, the number of different domains and their ratio could be widely variable on demand. Read More

Electrostatic Self-Assembly of Soft Matter Nanoparticle Cocrystals with Tunable Lattice Parameters.

ACS Nano 2015 Nov 28;9(11):11278-85. Epub 2015 Oct 28.

Biohybrid Materials, Department of Biotechnology and Chemical Technology, and ‡Molecular Materials, Department of Applied Physics, Aalto University , 00076 Aalto, Finland.

Atomic crystal structure affects the electromagnetic and thermal properties of common matter. Similarly, the nanoscale structure controls the properties of higher length-scale metamaterials, for example, nanoparticle superlattices and photonic crystals. Electrostatic self-assembly of oppositely charged nanoparticles has recently become a convenient way to produce crystalline nanostructures. Read More

Nonspherical double emulsions with multiple distinct cores enveloped by ultrathin shells.

ACS Appl Mater Interfaces 2014 Jan 9;6(2):1294-300. Epub 2014 Jan 9.

Department of Chemical and Biomolecular Engineering and KINC, KAIST , Daejeon 305-701, Korea.

Microfluidics has provided means to control emulsification, enabling the production of highly monodisperse double-emulsion drops; they have served as useful templates for production of microcapsules. To provide new opportunities for double-emulsion templates, here, we report a new design of capillary microfluidic devices that create nonspherical double-emulsion drops with multiple distinct cores covered by ultrathin middle layer. To accomplish this, we parallelize capillary channels, each of which has a biphasic flow in a form of core-sheath stream; this is achieved by preferential wetting of oil to the hydrophobic wall.

Proton MRI of (13)C distribution by J and chemical shift editing.

J Magn Reson 2001 Nov;153(1):117-23

INFM and Department of Physics, University of L'Aquila, I-67100 L'Aquila, Italy.

The sensitivity of (13)C NMR imaging can be considerably favored by detecting the (1)H nuclei bound to (13)C nuclei via scalar J-interaction (X-filter). However, the J-editing approaches have difficulty in discriminating between compounds with similar J-constant as, for example, different glucose metabolites. In such cases, it is almost impossible to get J-edited images of a single-compound distribution, since the various molecules are distinguishable only via their chemical shift. Read More

A stochastic approach for the interpretation of single pulse experiments in morphological multicompartments of renewing and exponentially growing cell populations.

J Theor Biol 1983 Mar;101(1):39-75

A general approach for the interpretation of single pulse experiments in multicompartment systems is presented. It allows an extension of the classical single compartment Barret's methodology, and has been detailed in the pipeline model case to show its capabilities. FLM, FLC, grain count curves, labelling indices and compartment size ratios of each compartment, are fitted into a coherent scheme that fully describes the statistical aspects of the phase durations including possible losses.
