Acetylation of tropical hardwood species from forest plantations in Costa Rica: an FTIR spectroscopic analysis
(2020)Acetylation of softwoods has been largely investigated to increase the dimensional stability and biological resistance of wood. However, the knowledge of this technology has not been applied to tropical hardwood species ... -
Almond and walnut shell-derived biochars affect sorption-desorption, fractionation, and release of phosphorus in two different soils
(2020)Effective soil phosphorus (P) management requires higher level of knowledge concerning its sorption-desorption, fractionation, and release, as well as its interactions with soil amendments including biochar (BC). The purpose ... -
Fire performance and leach resistance of pine wood impregnated with guanyl-urea phosphate/boric acid and a melamine-formaldehyde resin
(2020)Scots pine (Pinus sylvestris L.) wood impregnated with guanyl-urea phosphate/boric acid and a melamine-formaldehyde resin exhibited considerably increased resistance to leaching, while sustaining superior fire retardancy ... -
Fire Retardancy and Leaching Resistance of Furfurylated Pine Wood (Pinus sylvestris L.) Treated with Guanyl-Urea Phosphate
(2022)Guanyl-urea phosphate (GUP) was introduced into furfurylated wood in order to improve fire retardancy. Modified wood was produced via vacuum-pressure impregnation of the GUP– furfuryl alcohol (FA) aqueous solution, which ... -
Furfurylation of tropical wood species with and without silver nanoparticles: Part I: Analysis with confocal laser scanning microscopy and FTIR spectroscopy
(2021)This work focused on the upgrading of non-durable tropical wood species originating from fast-growing plantations of Costa Rica. Modification of such tropical woods with furfuryl alcohol, although has not been broadly ... -
Geo- and nano-materials affect the mono-metal and competitive sorption of Cd, Cu, Ni, and Zn in a sewage sludge-treated alkaline soil
(2019)We evaluated the effect of geomaterials (modified zeolite and bentonite using CaCl2) and nanoparticles (ZnO and MgO) on the mono-metal and competitive sorption of cadmium (Cd), copper (Cu), nickel (Ni), and zinc (Zn) in ... -
The in vitro antimicrobial activity assessment of ultrasound assisted Lycium barbarum fruit extracts and pomegranate fruit peels
(2019)The present study aimed at assessing the antimicrobial properties of a water and ethanol ultrasound-assisted extraction (UAE) of dry goji berries and of lyophilised powdered pomegranate peel in vitro. Minimum inhibitory ... -
Magnetic nanoparticles in medical diagnostic applications: Synthesis, characterization and proteins conjugation
(2016)Background: Magnetic nanoparticles (NPs) used in biomedical applications should be discrete with small particle sizes, narrow size distribution and superparamagnetic. NPs can be tailored to target, through chemical bonds, ... -
Self-Healing pH- and Enzyme Stimuli-Responsive Hydrogels for Targeted Delivery of Gemcitabine to Treat Pancreatic Cancer
(2018)A novel, multifunctional hydrogel that exhibits a unique set of properties for the effective treatment of pancreatic cancer (PC) is presented. The material is composed of a pentablock terpolypeptide of the type ... -
Wet chemical silver treatment of endotracheal tubes to produce antibacterial surfaces
(2007)Mechanically ventilated patients in hospitals are subjected to an increased risk of acquiring nosocomial pneumonia that sometimes has a lethal outcome. One way to minimize the risk could be to make the surfaces on endotracheal ...
