Abundance mass spectra, obtained upon carefully electrospraying solutions of tert-butanol (TB) in water into a mass spectrometer, display a systematic series of peaks due to mixed H(+)(TB)m(H2O)n clusters. Clusters with m + n = 21 have higher abundance (magic number peaks) than their neighbours when m ≤ 9, while for m > 9 they have lower abundance. This indicates that the mixed TB-H2O clusters ...

We synthesized and evaluated biodegradable and elastomeric polyesters (poly(glycerol sebacate) (PGS)) using polycondensation between glycerol and sebacic acid to form a cross-linked network structure without using exogenous catalysts. Synthesized materials possess good mechanical properties, elasticity, and surface erosion biodegradation behavior. The tensile strength of the PGS was as high as ...

Electro-hydrodynamic processing, comprising electrospraying and electrospinning techniques, has emerged as a versatile technology to produce nanostructured fiber-based and particle-based materials. In this work, an antimicrobial active multilayer system comprising a commercial polyhydroxyalkanoate substrate (PHA) and an electrospun PHA coating containing in situ-stabilized silver nanoparticles ...

Electrospraying a mixture of Ac-(GA)7K and Ac-A(GA)7K (Ac = acetyl, G = glycine, A = alanine, and K = lysine) peptides produces strong signals for unsolvated dimers and trimers. The conformations of these multimers have been examined with use of ion mobility measurements in conjunction with molecular dynamics simulations. The results suggest that the trimers adopt a pinwheel arrangement of heli...

We introduce an innovative method for patterning one or multiple types of polymeric microparticles by electrospraying them towards a collecting surface patterned with an array of microelectrodes. By independently programming the electric state of each microelectrode, microparticles can be confined within desired regions with a high patterning contrast. The patterning principle and the role of t...

Abundance mass spectra, obtained upon carefully electrospraying solutions of tert-butanol (TB) in water into a mass spectrometer, display a systematic series of peaks due to mixed H(TB)m(H2O)n clusters. Clusters with m + n = 21 have higher abundance (magic number peaks) than their neighbours when m r 9, while for m 4 9 they have lower abundance. This indicates that the mixed TB–H2O clusters ret...

A novel fused-droplet electrospray ionization (FD-ESI) source was developed to generate peptide and protein ions. The sample solution was first ultrasonically nebulized to form fine aerosols. The aerosols were then purged into a glass reaction chamber via nitrogen. Charged methanol droplets were continuously generated through electrospraying the acidic methanol solution from a capillary, which ...

Abstract. Two types of DC electrical discharges in atmospheric air (streamer corona and transient spark) were tested for decontamination and decoloration of water contaminated by bacteria and organic dyes. The flowing water passed through the high voltage (HV) needle electrode into the active discharge region. The bacteria were killed most efficiently by transient spark and streamer corona with...

Antimicrobial nanobunches with different amounts of chitosan-capped Ag were prepared by continuous gas-liquid green route under ultrasound irradiation. Spark-produced aerosol Cu nanoparticles were directly injected into an ultrasound Ag(I)-chitosan reaction cell for efficient hydrosolization of the Cu particles and the subsequent incorporation of Ag and chitosan on Cu. Subsequently, electrospra...

Tumor heterogeneity makes combination chemotherapy one of the preferred modes of treatment regimens. In this work, sequential exposure of two anticancer agents, paclitaxel (Tx) followed by topotecan (TPT), was shown to have a synergistic effect on non-small cell lung cancer (NSCLC) cell line, NCI-H460. In order to improve patient compliance, the aforementioned concept was translated into a drug...
