Interaction of lignin derivatives with polymers, ions and soft surfaces in aqueous systems
(2021)
Lignin is one of the most abundant biopolymers on earth which has recently gained considerable
attention due to its unique potentials to be used in many applications. Many efforts have been made
in improving the compatibility ...
Carboxyalkylated cullulose nanocrystals for novel applications
(2021)
Cellulose nanocrystals (CNC), rigid rod-like nanoparticles, are derived from cellulose through acid
hydrolysis and are considered as emerging nanomaterials according to their beneficial properties
and commercial availability. ...
Male outdoor educators’ understandings of masculinity in practice: a North American case study
(2021)
This exploratory, single embedded case study examined male outdoor educators’ understandings
of masculinity in the field and how such notions impact their practices. Data were collected via
interviews (n = 18), observations ...
Impact of physicochemical properties of lignin-based polymers on their flocculation and adsorption performance
(2021)
Industrial and municipal effluents contain colloidal charged particles, dissolved salts, heavy metals
and other impurities, which may represent varied health risks and must be removed before
discharge into the environment. ...
Narcissism predicts facial muscle reactivity during a body comparison threat: the role of personality in shaping affiliative behaviour
(2021)
The facial feedback hypothesis suggests that individuals automatically activate facial
muscles that are congruent with an expresser’s facial display, which in turn results in a congruent
emotional experience within ...
Drought effects on soil enzyme activity
(2021)
Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle
nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also
mineralizing and stabilizing gas. ...
Sulfo-functionalization of lignin and its impact on the stabilization of colloidal systems
(2021)
Lignin macromolecules, derived from renewable biomass resources, have gained extensive interest
during the past decade as a sustainable substitute for synthetic oil-based materials. The main goal
of this dissertation was ...
Design methodology for Class D ultrasound transducer drivers
(2021)
Ultrasound refers to sound waves with frequencies above the upper limit
of human hearing. Due to the high frequency, the energy can be concentrated and used for therapeutic applications, such as ultrasound imaging ...
Examining adverse childhood experiences in a First Nations treatment-seeking population
(2021)
Experiencing adversity during childhood can disrupt typical developmental pathways and
consequently affect health outcomes throughout the lifespan (Norman et al., 2012), particularly
for Indigenous populations in Canada ...
The impact of climate change on the phenology of short- and long-distance migratory birds
(2021)
Quickly changing temperatures due to climate change are expected to have
devastating consequences on the migratory bird populations around the globe. However,
surprisingly, several studies have demonstrated that some ...
