Polymer-clay Nanocomposites
No full textPhDPolymer-clay nanocomposites are attracting global interest principally because
property enhancements are obtained at low clay particle loadings (1-5 wt%).
However there is lack of fundamental understanding of such composites. The aim
of this work is to provide an insight into the interaction between polymer and clay.
This includes the driving force for intercalation, the reinforcement mechanisms and
property-volume fraction relationships.
Functionalised poly(ethylene glycol)-clay, poly(c-caprolactone)-clay and
thermoplastic starch-clay nanocomposites with a range of polymer molecular
weights, clay volume fractions and with different clays were prepared using
solution methods, melt-processing methods, and in situ polymerisation. A reliable
X-ray diffraction technique for low angle basal plane spacing of clay, the essential
parameter for structure determination, was established obtaining ±0.005 Mn
between three diffractometers. The basal plane spacing was found to be unaffected
by polymer molecular weight and preparation method but was affected by the
nature of the polymer and clay. Increasing clay loading could lead to a lower
spacing. As a cautionary observation, poly(ethylene glycol) with high molecular
weight (2: 10,000) was found to undergo degradation readily during preparation of
nanocomposites with and without clay.
Competitive sorption experiments for molecular weight showed that high
molecular weight fractions of polymer intercalate preferentially into clay during
solution preparation. Thermodynamic studies on the intercalation process found
that significant enthalpic change occurred during intercalation, which is coincident
with the observation that heat-treated clays without interlayer water can intercalate
polymer. The calculation of true volume fraction against nominal volume fraction
provided reasonable explanation of property enhancement and helps understand the
relation between nanocomposites and conventional composites. At a given clay
loading, nanocomposites with better dispersion gave more property enhancement
than those with lower dispersion or conventional composites. The crystallinity of
semicrystalline polymer was also affected by varying extents of dispersion of clay.
The use of X-ray diffraction with an internal standard was explored for quantitative
analysis of intercalation and exfoliation
Mineral acquisition from clay by Budongo Forest chimpanzees
No full textDate of Acceptance: 06/07/2015Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations. The presence of aluminium in the clay consumed indicates that it takes the form of kaolinite. We discuss the contribution of clay geophagy to the mineral intake of the Sonso chimpanzees and show that clay eaten using leaf sponges is particularly rich in minerals. We show that termite mound soil, also regularly consumed, is rich in minerals. We discuss the frequency of clay and termite soil geophagy in the context of the disappearance from Budongo Forest of a formerly rich source of minerals, the decaying pith of Raphia farinifera palms.Peer reviewe
Seawater redox variations during the deposition of the Kimmeridge Clay Formation, United Kingdom (Upper Jurassic): evidence from molybdenum isotopes and trace metal ratios
No full textThe Kimmeridge Clay Formation (KCF) and its equivalents worldwide represent one of the most prolonged periods of organic carbon accumulation of the Mesozoic. In this study, we use the molybdenum (Mo) stable isotope system in conjunction with a range of trace metal paleoredox proxies to assess how seawater redox varied both locally and globally during the deposition of the KCF. Facies with lower organic carbon contents (TOC 1–7 wt %) were deposited under mildly reducing (suboxic) conditions, while organic-rich facies (TOC >7 wt %) accumulated under more strongly reducing (anoxic or euxinic) local conditions. Trace metal abundances are closely linked to TOC content, suggesting that the intensity of reducing conditions varied repeatedly during the deposition of the KCF and may have been related to orbitally controlled climate changes. Long-term variations in ?98/95Mo are associated with the formation of organic-rich intervals and are related to third-order fluctuations in relative sea level. Differences in the mean ?98/95Mo composition of the organic-rich intervals suggest that the global distribution of reducing conditions was more extensive during the deposition of the Pectinatites wheatleyensis and lower Pectinatites hudlestoni zones than during the deposition of the upper Pectinatites hudlestoni and Pectinatites pectinatus zones. The global extent of reducing conditions during the Kimmerigidan was greater than today but was less widespread than during the Toarcian (Early Jurassic) oceanic anoxic event. This study also demonstrates that the Mo isotope system in Jurassic seawater responded to changes in redox conditions in a manner consistent with its behavior in present-day sedimentary environment
Aqueous Acid Orange 7 dye removal by clay and red mud mixes
No full textIn this study, Portuguese clay, Fe-impregnated clay, red mud and clay/red mud mixtures were used in the removal of Acid Orange 7 by Fenton and photo-Fenton (under UV light) oxidation processes. In comparison with pure adsorption, the catalytic activity of Fe-loaded clay showed an optimum removal rate (98%). This photo-assisted Fenton degradation of Acid Orange 7 azo-dye molecules was exploiting HO radicals from generated H2O2 and clay supported iron species, following the pseudo-first order kinetic mechanism.By using red mud pre-calcined at 400 °C, 10% improvement in overall discolouration was observed in comparison to the untreated clay. This improvement is attributed to the partial reduction of Fe3+ to Fe2+ species on the surface of the catalyst, and to the reaction with H2O2 to generate highly oxidative hydroxyl radicals. It was seen that the synergistic effect of photocatalysis due to the presence of TiO2 in the red mud also contributed in this photo-Fenton process. Furthermore, the use of red mud/clay catalyst mixes assured 38% dye discolouration at pH 7, but a lowering of solution pH to 3 resulted in a much higher discolouration rate (over 80% after 1 h). The good fitting with a pseudo-second-order kinetic model (R2 equals to 0.99) shows that adsorption processes could strongly contribute in the dye removal efficiency
Guide to the nature and methods of analysis of the clay fraction of tephras from the South Auckland region, New Zealand.
No full textThe manual outlines some of the more common laboratory procedures available for qualitatively and quantitatively analysing the composition of the tephric clays, many of which are difficult to determine because of their short range order or 'amorphous' nature. Techniques described and assessed in terms of their rapidity and quantitativeness include XRD, IR, DTA, TEM and SEM, sodium fluoride reactivity, chemical dissolution analyses, and surface area measurements. No one technique alone produces a definitive clay fraction analysis of tephric deposits. -from Author

Hello Rebels Family!
It's easy to believe that the rich and famous are born well...rich and famous. Not so! On the
way to being famous...Gwen Stefani worked at Dairy Queen, Madonna was fired from Dunkin'
Donuts, Brad Pitt handed out flyers wearing a chicken suit for El Polio Loco, Rachel McAdams
was a server at McDonald's and Beyonce was swept up hair in her mother's salon. There are
jobs you will have before you 'make it' too. Some you will enjoy. And some - not so much.
On my way to becoming a teacher I was a waiter, a landscaper, a tree planter, and a
bartender. Some of these jobs I liked and some I hated. But ALL of these jobs brought me to
the profession I love and shaped who I have become.
At W.R. Myers High School we are proud of being a school where every student can find an
avenue for success and in being part of a community where everyone in the Rebel family
strives to find the best in themselves and others. As Christian Larson said, "Believe in yourself
and all that you are. Know that there is something inside you that is greater than any obstacle."
Remember that you are the star of your own life and that, with hard work, your dreams will become reality!
Take care,
Ken Pon

Wow! What a year! I chose "REBEL RESILIENCE" as the yearbook theme this year as I thought it was rather fitting given our
current 'COVID-1 9' situation. Some of you are already VERY RESILIENT, while others may feel like you are not. One thing is
for sure - you can always WORK on becoming MORE resilient.
Here are 10 ways you can work on becoming more resilient:
Have the courage to be imperfect
Take time for yourself
Sign up for that course, join that club
Be active every day in as many ways as you can
Spend time with people who make you feel good
Laugh out loud each day
Invite your neighbor (friend) over for a cup of tea (chat)
Do one thing now that you've been putting off
Focus more on things you can control
Remember, this too shall pass (~https://wayahead.org.au/get-the-facts/building-resilience/)
Thank you to all those who gave me a big smile (or at least didn't run away) when I put the camera in front of your face! I
apologize to those teams I missed getting photos of (that actually had the opportunity to play). Because this year is unlike any
other, I also decided to change up the color scheme from the traditional red/black/yellow! I would love some feedback on
this decision (love it/dislike it etc).
A huge shout-out to a stellar group of grade 9's who helped me with the yearbook in June (Madisen and Bryden O'Connor,
Kiernan Gyepesi, Will Evanson, Madison Reid, Heston Bevans and Allen Clements). Thank you specifically to Bryden O'Connor
for creating the color graphic used throughout the yearbook.
Some of the quotes found through out the yearbook were from the survey you filled out in the spring, which in, most cases,
does not have the author information and therefore simply states the grade level the quote came from. All other quotes with
Author Unknown" were found online and in most cases didn't have any author information either. In any case, my hope is
that they will either put a smile on your face, make you go 'hmm' or possibly even take time to pause and reflect on the
message being shared. Enjoy! 5

A Message ■
from ou„r awth^lOtiC DiPOCtO
It was a sad reality that we all had to face this year with little to no athletic
competitions across the Province for High School Sport. But very thankfully, and
in true Rebel Spirit, we made the most of the situation and were able to organize
and provide our student-athletes with a few opportunities to participate in sport.
The Rebels made teams and practiced as much as they possibly could in football,
volleyball, cross-country, golf, basketball, and curling. Unfortunately, a few of our
traditional sports were not able to get off the ground in the Spring, but hopefully
that will only fuel the fire of the up and coming athletes for next season! We want
to give a big thanks to all those student-athletes and coaches who committed to
one or more of our teams during these tough, unprecedented circumstances, and
a special shout out to all the Grade 1 2 student-athletes for all of their years of
dedication to High School Sport!

The W.R. Myers Concert and
Stage Bands were unable to
perform this year due to COVID,
but we were lucky enough to still
be able to play our instruments.
Vince Gassi, a composer from
Toronto, was commissioned by
the W.R. Myers Band Parent
Association to write a piece for
the Concert Band. The band
students met with Mr. Gassi via
Zoom in October to talk to him
about the piece and the writing
process. He completed the piece
for us in January and we began
working on it. Again the band
students met with Mr. Gassi on
Zoom for him to listen to us play
and give feedback. But
unfortunately due to the COVID
restrictions, we were unable to
premier the piece. Hopefully,
next year we will be able to play

Sayge Turcato was in the Alberta
High School Rodeo Provincials
Finals at the beginning of June
she went into the finals as the
season leader in the Barrel
Racing and she was 8th in
District 1 for the Breakaway
Roping with a few go round wins
she ended up winning the
Alberta Finals in the Barrel
Racing and placing 4th in the
Breakaway. That qualified Sayge
to go to the National High School
Rodeo Finals 2021 in Lincoln,
Nebraska.
Way to go Sayge!!
Kayce Liptak has also had a great showing this year
so far. She placed 2nd at Provincials, just behind
Sayce Turcato. This meant that she also qualified to
go to the National High School Rodeo Finals 2021
in Lincoln, Nebraska.

The Taber Thrashers get a season after all! With vaccinate numbers up and COVID cases dropping substantially
after a short shutdown the Lacrosse league got the green light to play. And play they did! If you enjoy watching
playing a high-intensity, high-contact sport, then this is a game for you! With the Lacrosse league in its infancy in
^ber (this is just the second season of play) the team did a stellar job working on basic skills, learning plays, and
Alling as a team unit. They definitely had their ups and downs where the scoreboard was concerned. But considering
^ey were up against teams with many more years experience, the Thrashers had a phenomenal season!

Reactivity of the Clay Mineral Montmorillonite: A First Principles Study
No full textPhDThe recent development of clay-polymer nanocomposite materials has led to ail
increased interest in the structure and properties of clay minerals. In this thesis the
reactivity of the clay mineral montmorillonite is explored by means of density
functional theory based calculations. In particular three aspects are considered:
catalytic properties, cation migration and dehydroxylation.
The origin of the catalytic properties of the clay mineral is investigated in the
context of the synthesis of clay-polymer nanocomposite materials, by in sttu,
intercalative polymerisation. It is found that catalysis is most likely to occur at the
clay mineral lattice-edge where exposed aluminium atoms act as Lewis acid sites.
Migration of lithium cations into the clay mineral lattice is explored by
means of first principles molecular dynamics. Comparison of calculated hvdrox-vl
stretching frequencies, with those from experiment indicates that cations migrate to
vacant octahedral sites, as oppose to the ditrigonal cavities.
Dehydroxylation of the clay mineral is examined by consideration of a cis-vacant
pyrophyllite structure. It is shown that dehydroxylation leads to formation of a
tyan8-vacant structure, with aluminium in trigonal bipyramidal coordination and a
highly distorted tetrahedral layer. Differences in the dehydroxylation behaviour of
cm and tran8-vacant pyrophyllite are shown to be due to the fact that in the
former adjacent hydroxyl groups bridge different pairs of aluminium atoms,
while in the latter they are both bonded to the same pair.
Overall density functional theory based calculations are shown to be
a powerful tool for the studly of the structure and reactivity of clay minerals.Queen Mary University of London

Polymer-based treatments to control runoff, leachate and erosion from engineered slopes at Simfer Mine, Guinea, Africa
No full textIt is necessary to understand the erodibility and hydrological response of mine-site slope forming materials (SFMs), because of increasing awareness of the environmental impacts of mining. Steep engineered slopes in high intensity rainfall environments present a serious erosion risk. Temporary surface stabilisers, such as polyacrylamides (PAMs) and polyvinylacrylic latex (PVALs) are potentially cost effective erosion control solutions. In this study PAM and PVAL efficacy to reduce runoff, leachate and erosion was assessed at two application rates, with and without gypsum on SFMs from an iron ore mine in Guinea (West Africa). NSPASS (near-surface photogrammetry assessment of slope forming materials’ surface roughness) is a novel method that integrates digital image capture and GIS. It is shown to detect and quantify surface micro-relief changes of 2-3 mm, not visible to the naked eye.
As expected, soil and non-soil SFMs were significantly different in terms of their physical and chemical properties. Phase I of the study investigated the erodibility of ten SFMs, including soil, ore and waste-rock. The results indicate that the hydrological response to rainfall of most SFMs is to generate leachate. Weathered phyllite (PHY-WEA) is the most erodible SFM by both runoff and leachate. Multiple regression analysis demonstrated that magnetic susceptibility, mineralogy and dry aggregate distribution; parameters not commonly assessed in erosion studies, are important in explaining SFM erodibility and hydrological response.
Phase II evaluated critically the effectiveness of three commercially available polymer solutions (two PAMs and one PVAL) at reducing runoff, leachate and erosion from four of the most erodible SFMs identified in Phase I. The results indicate that some PAM and PVAL treatments significantly reduce runoff, leachate and erosion. Polymer efficacy is highly dependent on the physical and chemical properties of the SFM, as well as the mechanism of polymer to SFM adsorption. Increasing the application rate of select treatments lowered leachate volumes, runoff and leachate total sediment loads. Contrary to previous studies, gypsum amendments did not significantly improve polymer efficiency.
This research has added to our understanding of the erodibility and hydrological response of soil and non-soil SFMs. This is the first study to evaluate critically the efficacy of PVALs in controlling erosion from mine-site SFMs. Future studies should continue to optimise NSPASS performance in monitoring changes in surface micro-relief
Predicting shear strength mobilization of London clay
No full textWhen designing geotechnical structures engineers need to assign soil parameters. Soil design parameters are often inferred through correlations with basic site investigation data. The objective of this work is to determine the shape of the undrained stress-strain curve of a heavily overconsolidated Eocene clay in such a way that it may conveniently be used in simplified deformation mechanisms to predict ground movements due to construction. A database of London clay triaxial test data is presented. Use of a power model to predict strength mobilization is demonstrated for 17 previously published triaxial tests on high quality cores of London clay. A novel method of normalising these mobilization curves is demonstrated (using a reference strain at 50% mobilization of shear strength), and different relations are shown to apply to different magnitudes of strain. The parameters that influence the variation of the reference strain are studied
