Advances and gaps in Natech quantitative risk analysis
(2021-12-26)
Article
Open AccessThe occurrence of Natech (natural hazard triggering technological disasters) accidents has generated a reflection about the need to manage adequately the risk to people, to the environment, and to the infrastructures ... -
The influence of Ni2+ and other ions on the trigonal structure of DNA
(Wiley, 2021-04-13)
Article
Restricted access - publisher's policyWe present a new structure of a DNA dodecamer obtained in the presence of Ni2+ ions. The DNA forms Ni-guanine cross-links between neighboring molecules. Our results show that an adequate dosage of Ni2+ may help to form ... -
Surface modification of polyester fabrics by ozone and its effect on coloration using disperse dyes
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-01)
Article
Open AccessPolyester fibers (PES) are the most consumed textile fibers due to their low water absorption; non-ionic character and high crystallinity. However, due to their chemical structure, the chemical interactions between polyester, ... -
Effects of water deficit irrigation on phenolic composition and antioxidant activity of monastrell grapes under semiarid conditions
(2021-08-01)
Article
Open AccessThe high phenolic compound content of grapes makes them an important source of natural antioxidants, among other beneficial health properties. Vineyard irrigation might affect berry composition and quality. Regulated deficit ... -
Poly(butylene succinate-co-e-caprolactone) copolyesters: Enzymatic synthesis in bulk and thermal properties
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-11)
Article
Open AccessThis work explores for the first time the enzymatic synthesis of poly(butylene-co-e-caprolactone) (PBSCL) copolyesters in bulk using commercially available monomers (dimethyl succinate (DMS), 1,4-butanediol (BD), and ... -
Comparative anaerobic decolorization of AZO dyes by carbon-based membrane bioreactor
(2021-04-02)
Article
Open AccessThis study used a novel integrated technology of ceramic supported carbon membrane(CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneouslyas biofilm support, redox mediator, and nano-filter ... -
GTR/NBR/Silica composites performance properties as a function of curing system: sulfur versus peroxides
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-09-15)
Article
Open AccessIn this work, conventional sulfur and two types of organic peroxides (dicumyl peroxide (DCP) and di-(2-tert-butyl-peroxyisopropyl)-benzene (BIB)) curing systems were used to investigate the possibility for tailoring of the ... -
Economic and environmental assessment of plastic waste pyrolysis products and biofuels as substitutes for fossil-based fuels
(2021-06-24)
Article
Open AccessThe global economy is shifting toward more sustainable sources of energy. The transportation sector is a remarkable example of this fact, where biofuels have emerged as promising alternatives to traditional fossil fuels. ... -

(2021-09-02)
Article
Restricted access - publisher's policyHemp (Cannabis sativa L.) is a plant of which, its ease of cultivation, structure and properties, provide it great potential for industrial applications; nevertheless, the unfavorable content of lignin complicates its ... -
Low-temperature methane partial oxidation over Pd supported on CeO2: effect of the preparation method and precursors
(MDPI AG, 2021-02-17)
Article
Open AccessThe catalytic production of syngas by the partial oxidation of methane (POM) was investigated over Pd supported on ceria (0.5–2 Pd wt.%) prepared by incipient wetness impregnation and by mechanochemical methods. The ...
