Polylactic acid (PLA) microfibrous composite scaffolds having hydroxy apatite (HA) particles in the fibers were prepared by electrospinning of PLA and wet chemical hydrothermal reaction HA with average diameter of 8.13 µm. The fibers were compressed in mould into bulk scaffolds. Microscopy characterizations confirmed integration of the crystalline HA and PLA fibers in both before and after compression.

Ebook "Smoke, dust, and haze: Fundamentals of aerosol dynamics" covers the effects of turbulence on coagulation and gas-to-particle conversion and also discusses the formation of primary particles by the collision-coalescence mechanism. The chapter on the atmospheric aerosol has been completely rewritten within the aerosol dynamics framework. Its basic approach and topicality make Smoke, Dust, and Haze: Fundamentals of Aerosol Dynamics, 2/e, an essential guide for both students and researchers.

The dependence of the magnetic responsiveness on magnetite nanoparticle size has been studied. Monodisperse magnetite nanoparticles of 10 nm diameter were prepared by an ultrasonically enhanced co-precipitation procedure. A carboxyl-functionalised solvothermal approach was applied to synthesise magnetite nanoparticles with an average size of 30 nm.

The cross-linked microbeads with average diameter of 106–300 μm, [poly(EGDMA-MATrp)], were obtained by copolymerization reaction of N-methacryloyl-L-(+)-tryptophan methyl ester (MATrp) with ethylene glycol dimethacrylate (EGDMA) and successfully applied as a heterogeneous catalyst in conjugate addition reaction of nitromethane to substituted 2-iminochromenes in aqueous media. A variety of 2-amino-4-(nitromethyl)-4H-chromene-3-carbonitriles has been synthesized in good yields. Polymeric microbeads were very durable and reused 5 times without a significant loss of activity.

Median diameters (D50) of suspended particles were inferred in the wet season in the Cam - Nam Trieu estuary (Hai Phong, Vietnam) based on the particle size distribution measured by LISST-100X on five transects along the river from 23 to 26 September 2015. The results showed that floc diameters varied between 3.6 μm to 146.5 μm and averaged 49.14 μm.

Studying four species of red wood ants (Formica rufa, F. polyctena, F. aquilonia, F. lugubris), we examined nest morphometrics (height and diameter of anthills), spatial parameters (location of anthills of different sizes relative to each other), and the number of trails per colony in three regions of Ukraine and Russia: Kyiv region (877 anthills), the Urals (274 anthills) and Cis-Baikal (72 anthills). We have established a relationship between the number of anthills in the nest complex and the maximum parameters of the average height and diameter, as well as the average number of trails.

Immobilized metal chelate affinity chromatography (IMAC) support was practiced for α-amylase immobilization. Poly(hydroxyethylmethacrylate-methacryloylamidotryptophan)-Ni2+[p(HEMA-MAT)-Ni2+] nanospheres, average diameter 100 nm, were produced by surfactant free emulsion polymerization. Characterizations of p(HEMAMAT)-Ni2+ nanospheres were carried out by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscope (SEM). In addition, average particle size, size distribution, and surface charge were specified.

In this study, the ethanol degradation ability of the catalyst, which was added with 0; 0.5; 1, and 1.5% liquid glass and calcined at 400 and 500 oC, was determined. TiO2 nanotubes after preparation have a uniform diameter from 10-12 nm and an average length of about 150nm, specific surface area increases markedly compared to commercial granules (nearly 15 times).

The results show that the cerium oxide spherical nanoparticles built from primary nanoparticles with the average size of ~5 nm, exhibited dispersion and uniform size and shapes with their average particle diameter of ~50 nm in size. With such a good morphology, CeO2 material possessed good catalytic activity for the decomposition of methylene blue (MB), in which the material was synthesized at a hydrothermal temperature of 80 oC (CeO2-80) for the best MB decomposition performance.

Melamine-formaldehyde resin (MFR) microparticles with average diameters of 1.06 µm were synthesized with PEG-20000 as the particle-forming agent. Palladium nanoparticles were entrapped in and adsorbed on the MFR microparticles, consecutively. Scanning electron microscopy (SEM) was used to characterize the morphologies of MFR microparticles. X-ray diffraction (XRD) and transition electron microscopy (TEM) showed that the palladium nanoparticles entrapped in the MFR microparticles dispersed much more homogeneously than those adsorbed on the MFR microparticles.

In this study, 3,4-dihydroxy-L-phenylalanine (L-Dopa) was solvothermally polymerized to monodisperse microspheres 1 µm in diameter. Polymerization was carried out in dimethylformamide containing appropriate amounts of urea and L-Dopa at 120 ◦ C for 24 h. Synthesis of the polymer in basic aqueous solution under hydrothermal conditions or via conventional heating resulted in the formation of bulky powders including irregularly shaped particles of the polymer. The morphologies of the synthesized polymers were characterized by scanning electron microscopy (SEM).

Fe(II)-montmorillonites (Fe(II)-MMTs) were prepared by mixing solutions of Fe(II) and montmorillonite at pH 3.5. Two different Fe(II)-MMTs were prepared and the ferrous iron contents were 40 mg/L and 80 mg/L. All samples were characterized by XRD, FT-IR, TGA, DSC, and nitrogen adsorption. By nitrogen adsorption, the pore size can be obtained in the pore diameter curve with average pore widths of 6.67 nm, 9.96 nm, and 17.07 nm, respectively.

The biocompatibility of nanocomposites was assessed by haemolytic, cytotoxic, and quantitative reverse transcription PCR (qRT-PCR) assays. FT-IR and PXRD results revealed that nanocomposites consisted of pure MOFs and PPy. Moreover, SEM results indicated their spherical morphology along with an average diameter of 190 nm. (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed a concentration, and percentagedependent cytotoxic effect of the nanocomposites on some cell lines including 3T3 fibroblasts, MCF-7, and J774.A1 macrophages.

In this study, carbon nanotubes (CNTs) added polyacrylonitrile/polypyrrole (PAN/PPy) electrospun nanofibers were produced. Average diameters of the nanofibers were measured as 268 and 153 nm for 10 and 25 wt% of PPy contents, respectively. A relatively higher strain to failure values (23.3%) were observed for the low PPy content. When as-grown CNTs (1 and 4 wt%) were added into the PAN/PPy blends, disordered nanofibers were observed to form within the microstructure. To improve the interfacial properties of CNTs/PAN/PPy composites, CNTs were functionalized with H2SO4/HNO3/HCl solution.
