Nanoscale Processing by Adaptive Laser Pulses
, 2002 We theoretically demonstrate that atomically-precise ``nanoscale processing" can be reproducibly performed by adaptive laser pulses. We present the new approach on the controlled welding of crossed carbon nanotubes, giving various metastable junctions of

Chemistry – A European Journal, EarlyView.A versatile method was developed to fabricate hierarchically porous monoliths using UiO‐66/TOCNC composites as Pickering emulsion stabilizers. The resulting polyHIPEs, produced under mild and scalable conditions, showed confirmed structural integrity through TGA, XRD, SEM, BET, and FT‐IR.

Influence of Mucilage Viscosity On The Globule Structure And Stability Of Certain Starch Emulsions [PDF]
, 2005 A study was carried out to determine the influence of mucilage viscosity on the globule structure (i.e. size and number) of certain starch emulsions. The starches investigated were cassava, potato and maize.

Model for hypernucleus production in heavy ion collisions
, 2010 We estimate the production cross sections of hypernuclei in projectile like fragment (PLF) in heavy ion collisions. The discussed scenario for the formation cross section of hypernucleus is: (a) Lambda particles are produced in the participant region but

Chemie Ingenieur Technik, EarlyView.Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor
The Canadian Journal of Chemical Engineering, EarlyView.A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Characterization of a two‐phase hybrid flotation column
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study explored the performance of a novel hybrid flotation column, which combines the advantages of a mechanically agitated cell with a flotation column and compared the results with a conventional flotation column setup. The experiments were performed in an air/water two‐phase system under varying airflow rates, frother concentrations ...
