Molecular dynamics simulations for the prediction of the dielectric spectra of alcohols, glycols, and monoethanolamine [PDF]
The response of molecular systems to electromagnetic radiation in the microwave region (0.3–300 GHz) has been principally studied experimentally, using broadband dielectric spectroscopy.

Eco-friendly methods of reducing the consequences of winter maintenance in urban green areas
Trees play a crucial role in the urban environment. They fulfil aesthetic, sociocultural, ecological, health-promoting and economic functions. Urban development and related human activity bring many risks to green areas within urban space.

Effects of cryoprotectant concentration and cooling rate on vitrification of aqueous solutions
Vitrification of aqueous cryoprotectant mixtures is essential in cryopreservation of proteins and other biological samples. We report systematic measurements of critical cryoprotective agent (CPA) concentrations required for vitrification during plunge ...

Palladium-bismuth intermetallic and surface-poisoned catalysts for the semi-hydrogenation of 2-methyl-3-butyn-2-ol [PDF]
The effects of poisoning of Pd catalysts with Bi and annealing in a polyol (ethylene glycol) were studied on the semi-hydrogenation of 2-methyl-3-butyn-2-ol (MBY).

Hydrophilicity as a measure of the efficiency of the superplasticisers
This paper presents the results of chemical structural investigations of four new-generation superplasticizers (denoted here as SP-A through SP-M2) used in concrete production engineering. The commercial product samples, the gel permeation chromatography

Polyester Polyols from Waste PET Bottles for Polyurethane Rigid Foams [PDF]
This paper describes a modified process to produce polyester polyols from PET wastes derived from the “bottle fraction residue” of the German Dual System (DSD) [11] employing a waste oligoester condensate of the polyesterification process with the ...
