Analysis and experimental demonstration of forced periodic operation of an adiabatic stirred tank reactor: Simultaneous modulation of inlet concentration and total flow-rate
(Chemical Engineering Journal, 2021)
It is well known, that forced periodic operation possesses the potential for process improvements. Nevertheless, only a small number of applications is reported, due to complex realization, limited predictability and high ...
Twin nucleation from a single lt c plus a > dislocation in hexagonal close-packed crystals
(Acta Materialia, 2021)
Twinning plays an important role in governing the balance between strength and ductility in hexagonal-close-packed (HCP) metals. Here, we report a combined experimental and theoretical study of twin nucleation from a single ...
Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Progress in Organic Coatings, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using alpha,omega-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Electrokinetic and sorption properties of hydrogen peroxide treated flax fibers (Linum usitatissimum L.)
(Cellulose, 2021)
Hydrogen peroxide represents an ecologically and economically acceptable agent for bleaching of flax fibers. The influence of hydrogen peroxide treatment under different conditions, i.e. hydrogen peroxide concentrations ...
Design and thermo-economic evaluation of an integrated concentrated solar power-Desalination tri-generation system
(Energy Conversion and Management, 2021)
In this work, a concentrated solar power (CSP) tri-generation system that is capable of the simultaneous production of steam, power and freshwater is introduced. The abundantly available direct normal irradiance can ...
Characterization of potential probiotic strain, L. reuteri B2, and its microencapsulation using alginate-based biopolymers
(International Journal of Biological Macromolecules, 2021)
In this study, Lactobacillus reuteri B2 was isolated from the feces of C57BL/6 mice and assessed on probiotic activity. L. reuteri B2 was identified by 16S rDNA sequencing, which the cell viability in acidic conditions at ...
Recommendations for replacing PET on packaging, fiber, and film materials with biobased counterparts
(Green Chemistry, 2021)
This review sheds light on urgent questions that arise from the need to replace a polymer resin,-poly(ethylene terephthalate), which represents 7.7% market-share in the global plastic demand (Plastics-the Facts 2019), by ...
The chitosan-based bioactive composite coating on titanium
(Elsevier B.V., 2021)
This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin on titanium substrate. ...
Halochromic cellulose textile obtained via dyeing with biocolorant isolated from Streptomyces sp. strain NP4
(Cellulose, 2021)
Halochromic (pH-responsive) material was obtained by dyeing functionalized viscose fabric with a crude extract from Streptomyces sp. strain NP4. The functionalization of the fabric before dyeing was performed to make ...
Spatial distribution, radiological risk assessment and positive matrix factorization of gamma-emitting radionuclides in the sediment of the Boka Kotorska Bay
(Marine Pollution Bulletin, 2021)
Surface sediment from the Boka Kotorska Bay (Adriatic Sea) was analyzed for the content of technogenic cesium (137Cs) and naturally occurring (40K, 226Ra, 232Th, 238U) radionuclides. The activity concentrations of the ...
