Abstract:
Currently, the relevance of reuse of agroindustrial waste to obtain fillers in micro- and nano-sizes for the development of biocomposite materials has grown significantly. Production processes based on sustainable and low carbon development have increased interest in more environmentally friendly polymer composites, which have made the origin of reinforcement materials a determining factor for their application in this segment. This work presents a review of the developments of our team in the field of thermoplastic biocomposites reinforced with micro- and nano-sized fillers extracted from agroindustry residues. The different residues from Brazilian agroindustry available for the extraction of micro- and nano-sized fillers for the production of polymer biocomposites, the methods of the extraction and treatments of these natural fillers are presented; and its application as reinforcements in thermoplastic-based biocomposite are discussed in this review.

Abstract:
Chronic wounds are skin injuries with failed healing. They have become a
public health problem that affects more than 2% of the population and the presence of
bacteria resistances difficult of treatment. Pseudomonas aeruginosa is opportunist
pathogens and the treatment is difficult and requires a long period of treatment.
Hydrogels are structure polymeric tridimensional and biocompatible. They have been
used as a controlled delivery system for treatment of topic infection. Studies have
reported calcium carbonate and silver ion can improve the mechanical properties and
biocide activity of hydrogel. Here in this study, hydrogels loaded CaCO3-Ag were
prepared using poly (N-vinyl-2-pyrrolidone), poly (ethylene glycol), agar, calcium
carbonate, silver nitrate followed gamma irradiation with 25 kGy dose. The gel
fraction, behavior swelling and biocide action against P. aeruginosawas investigated.
The degree of swelling of the hydrogel loaded CaCO3-Ag was 12% higher than the
unloaded and exhibited antibacterial effects against P. aeruginosa and biofilm.

Abstract:
Plastics have been replacing other traditional materials such as wood,
metal and glass over the past decades due to its versatility in properties, processability,
and cost. Polypropylene can be highlighted as one of the main thermoplastics
used in industry since it presents properties suitable for various applications, combining
density, cost, availability, and ease of molding. By considering the mechanical
recycling of post-consumer or post-industrial material, difficulty in flowability is
observed, which demands modification to promote processability. This work used
the traditional solution for flow modification (peroxide) and elastomeric modifier
to evaluate the impact of these additives on the mechanical and flow properties of
recycled polypropylene by tensile strength, melt index and spiral flow analyses.
Although the modified sample with organic peroxide had a higher melt flow index,
the mechanical resistance was lower than the elastomeric modifier, which showed
good performance in the material flow during processing according to spiral flow
analysis.

Abstract:
Thiswork aimed at the synthesis of graphene oxide (GO) and its reduction
in reduced graphene oxide (rGO), as well as the characterization of the obtained GO
and of each of the products of the various GO reduction methods. The characteristics
of the GO and rGO samples were compared in order to study the results for
each reduction method. Graphene oxide was synthesized, from the modified Hummers
methodology, using powdered graphite and subsequently reduced to rGO by
different methods (chemical method: reduction with hydrazine and carbon–C-dots
nanoparticles, and physical: ultrasound). The samples obtained from graphene oxide
and reduced graphene oxide were characterized electrically and microstructurally.
The results showed that the samples of GO reduced with hydrazine were those that
obtained the best results of conductivity and good restructuring of the sp2 hybridization,
followed by the carbon nanoparticles and ultrasound.

Abstract:
Foamed polymers are future materials, considered “green materials” due to their
properties with very low consumption of raw materials; they can be used to ameliorate
appearance of structures besides contributing for thermal and acoustic insulation.
Nevertheless, waste disposal has generated about 20–30% of total of solid
volume in landfills besides prejudicing flora and fauna by uncontrolled disposal.
The development of biodegradable polymers aims to solve this problem, considering
that in 2012, bio-plastics market was evaluated in 1.4 million tons produced and
in 2017 attained 6.2 million tons. Biodegradable polymers as poly(lactic acid) (PLA)
and poly(butylene adipate-co-terephthalate) (PBAT) are thermoplastics which can
be processed using the most conventional polymer processing methods. PLA is high
in strength and modulus but brittle, while PBAT is flexible and tough. In order to
reduce interfacial tension exhibited by PLA/PBAT blends, it was used as compatibilizing
agent 5 phr of PLA previously gamma-radiated at 150 kGy. Ionizing radiation
induces compatibilization by free radicals, improving the dispersion and adhesion
of blend phases, without using chemical additives and at room temperature. As
a reinforcement agent, calcium carbonate from avian eggshell waste was used, at
10 ph of micro particles, 125 μm. Admixtures were further processed in a singlescrew
extruder, using CO2 as physical blowing agent (PBA). Property investigations
were performed by DSC, TGA, XRD, SEM, FTIR, and mechanical essays.

Abstract:
Crystal Violet (CV) is widely used for various purposes and enters into
the aquatic systems from the effluents of textile, paint, medical and
biotechnological industries. A considerable amount of this dye is lost
during manufacturing and processing operations. Contaminated
wastewater containing CV must be treated before releasing in the
environment because it is highly cytotoxic and carcinogenic to
mammalian cells, present mitotic poisoning nature and is nonbiodegradable
being classified as a recalcitrant molecule. This chapter
reports the removal of CV dye from water using surfactant-modified zeolite from coal fly ash (MZSF), surfactant-modified zeolite from coal
bottom ash (MZSB) and nanosilica from sugarcane waste ash (SiO2NP).
The adsorbent materials were characterized to obtain chemical and
mineralogical composition and others physicochemical properties. The
adsorption kinetic of CV onto adsorbents was discussed using the
pseudo-first order, pseudo-second order, and Elovich models. The
Langmuir and Freundlich isotherm models were used to describe the
equilibrium adsorption data. The maximum adsorption capacities were
36.7 mg g-1 and 21.1 mg g-1 for CV/MZSF and CV/MZSB, respectively.
The adsorption process of CV/SiO2NP achieves equilibrium in 60 min of
contact time, and the maximum adsorption capacity was 117.98 mg g-1.
Application of the adsorbent materials synthesized from agricultural
waste and coal combustion products can ensure the sustainability and
cost-effectiveness of treating effluent containing CV dye, especially
effluent from the textile industries generated in large quantity.

Abstract:
The recycling of expanded polystyrene (EPS) by the use of ethyl acetate,
a biodegradable solvent is an alternative by the regular recycling process. Due to
the fragility of the polystyrene (PS), 2 wt% of glycerol was added in the recycled
expanded polystyrene (REPS) to increase the mobility of the polymer chains reducing
the brittleness of this material. As a dispersed phase was used recycled gypsum from
construction waste. 5, 10, and 15 wt% of recycled gypsum were used to obtain composites
by melt extrusion.Virgin PS, RPS, RPS/Glycerol, and RPS/Glycerol/Gypsum
composites were characterized by Thermogravimetric Analysis (TG), Differential
Scanning Calorimetry (DSC), Field Emission Scanning Electron Microscopy (FEGSEM),
and flammability test. The results showed that the addition of glycerin plasticized
RPS and Gypsum particles improved the thermal stability. In the flammability
test, the samples containing gypsum do not extinguish the flames of the material, this
phenomenon was not observed in the other compositions.

Abstract:
Waste materials have been frequently used as reinforcing materials, to
obtain a composite with better properties. Piassava palm is native to the state of Bahia
(Brazil) and its fiber, piassava fiber (PF) is awaste material frequently used for industrial
and domestic brooms, industrial brushes, carpets, and roofs. The light green clay
(LGC) is a natural smectite Brazilian clay from the state of Paraiba. This work aims
to produce and evaluate the advantages of this new product achieved by the inclusion
of these two natural materials into polypropylene (PP) matrix. A melting extrusion
process, using a twin-screw extruder and injection molding machine was used to
obtain PP/LGC (97/3 wt%), PP/PF (90/10 wt%) and PP/LGC/PF (87/3/10 wt%)
composites. The materials were characterized by mechanical tests, TG, DSC, SEM,
and XRD analysis.

Abstract:
An overview of neutron activation analysis (NAA) and some applications for this technique are provided in this paper. The fundamentals of the various methods of NAA (INAA, relative, k0, large sample, prompt gamma charge particles, cyclic, molecular and radiochemical NAA) are discussed in order to describe the most important scientific and technical aspects. Several problems associated with the technique are pointed out and briefly discussed. Emphasis is laid on the advantages of this technique for the determination of trace elements in geological, biological and environmental samples as an alternative analytical technique where other methods would not be the best choice.

Abstract:
The geometric increase in the production and exploitation of plastics
worldwide has several advantages as well as disadvantages due to the mismanagement
of plastic waste. These waste products find its way into the aquatic body.
Microplastics are plastic particles with its longest diameter less than or equal to
5 mm. Their microscopic nature, irregular color and morphology have made their
extraction from the buoyant organic materials problematic. This work documents for
the first time, the sampling and sample extraction of microplastics in Nigeria. An optimized
sampling and sample extraction protocol for surfacewaterwas developed. The
extraction protocolwas developed in a laboratory study using a simulated sample that
mimics the environmental sample (microplastics+organic materials). A micronized
LDPE (<300 μm) was used for the study and yielded a percentage recovery rate
of 82%. The digested microplastics which were subjected to SEM analysis showed
a slight change in the surface morphology. Thereafter, the environmental sample
was extracted using the developed laboratory protocol and a high positive result was
achieved. This protocol improved NOAA’s method of extraction by excluding the
use of microscope for the final extraction, which, of course, will yield a biased result.
This was achieved by the addition of ethanol to the final solution.

Abstract:
Elemental mercury is highly toxic and may be absorbed by dental professionals through direct skin contact or inhalation. The use of mercury in dental amalgam has been a concern of the academic community for years, for its incorporation is likely to affect vital organ systems. Several studies have been conducted to address the possible risks of occupational exposure to mercury vapor in dental offices. The present study aimed to present evidences that mercury is assimilated by exposed workers through the determination of urinary mercury (HgU) from dental professionals (n = 91) of public offices in Araguaína (Tocantins, Brazil). This uptake was verified against samples from unexposed individuals (n = 43), which activities are not dentistry related. Cold vapor atomic absorption spectrometry (CV-AAS) technique enabled the subjects’ biological monitoring. Approximately 44.8% (n = 60) of the 134 participants were aged between 21 and 30 years and were at the beginning of their professional lives; 9.7% (13) of the study participants were men and 90.3% (121) were women. Hg concentrations in all samples analyzed were within the maximum biological limit set by the World Health Organization (WHO) (<50 μgHg·L−1). HgU concentrations in dental professionals were within the limits proposed by the Brazilian regulatory standard, Regulatory Norm-7 (RN-7) (≤35 μgHg·g−1 creatinine). Nevertheless, the average concentration of HgU was approximately 8 times higher in the potentially exposed group (5.61 μgHg·g−1 creatinine) than in the unexposed group (0.65 μgHg·g−1 creatinine), highlighting the potential risk of occupational exposure to mercury.

Abstract:
The inorganic halloysite nanotubes (HNTs) are a promising type of natural
occurring filler for polymers. Its characteristics such as high aspect ratio (10–50),
small size, and high strength (elastic modulus—140 GPa) suggest that HNTs have
a potential use in high-performance polymer nanocomposites. Compared to other
nanoclays and nanosilica, the relatively low content of hydroxyl groups on their
surfaces makes HNTs relatively hydrophobic, although, sometimes, this is not sufficient
for guaranty a good interfacial adhesion in composite systems. In the present
study, halloysite nanotubes were incorporated in a polyamide 11 (PA11) matrix by
melt extrusion, using a twin-screw extruder and injection molding machine. The
neat PA11 and PA11/HNT nanocomposites were characterized by mechanical tests
(tensile, flexural and impact tests), and the correlation between properties were discussed.

Abstract:
The purpose of present study is to evaluate the antimicrobial potential of
Thermoplastic Polyester Elastomer (TPE-E) incorporated with zinc oxide added with
colloidal dispersion of metallic silver adsorbed on pyrogenic silica (AgNPs_ZnO).
A combination of single screw extruder and hot press technique was used to fabricate
these polymer nanocomposite films. These polymer nanocomposite films were prepared
by mechanical mixing of 1% (w/w) of oil, anti-oxidant 0.05% (w/w), TPE-E
granules 0.5% (w/w) and followed by single screw extruder to produce the pellets.
As-prepared pellets were further melted for films in hot press technique. Antimicrobial
activity was evaluated according to Japan Industrial Standard—JIS Z 2801
in TPE-E compounds against Staphylococcus aureus (S. aureus) and Escherichia
coli (E. coli). TPE-E samples containing additives 0.05 and 0.5% AgNPs_ZnO presented
75 and93%bactericidal reduction for Gram-negative bacteria Escherichia coli
(E. coli) and 76 and 92% bactericidal activity reduction for Gram-positive bacteria
Staphylococcus aureus (S. aureus), respectively.

Abstract:
Environmental sustainability demands the advancement in water treatment and
the use of lighting natural resources. Brazil has one of the most stable and intense
solar irradiation in the world. It has to be used not only for energy generation
purposes but also and mostly for water treatment, water quality polishment, and
furthermore water disinfection. The chapter performs a comparison of different
green technologies for water treatment as natural solar irradiation, simulated solar
photolysis, solar photo-Fenton with and without hydrogen peroxide addition (solar/
Fe), solar photo-Fenton with and without peroxide (solar/Fe/H2O2), titanium
oxide-mediated photocatalysis (UV/TiO2), photolysis under UV irradiation, and
UV treatment with hydrogen peroxide (UV/H2O2). The chapter describes the solar
photodecomposition calculations for pharmaceuticals and the emerging pollutants
mostly found in polluted waters, including the decomposition route, kinetics, and
process parameters. Many published works to point out the important properties to
evaluate catalyzer and semiconductor materials after their use in photodecomposition
processes. The essay includes the solar photodecomposition of dyes, carbamazepine,
hormones, acetaminophen, antipyrine, bisphenol A, antibiotics, and
the photodecomposition by-products. Finally, the chapter presents the synergistic
effect between them with the probable mechanism and mineralization degree.

Abstract:
The aim of this work is to obtain, characterize and irradiate the
DGEBA/EPDM compound and compare their thermal and mechanical properties
with a non-irradiated DGEBA/EPDM compound. The DGEBA/EPDM compound
may be used to cover other materials such as polymers and protect them against high
thermal conditions and mechanical effort. The compounds have 0.0, 25.0 and 50.0
wt% of DGEBA. In addition, the compounds were irradiated at 30 and 60 kGy at
a dose rate 22.41 kGy/s. The thermal properties (DMA and TGA) and mechanical
analysis (tensile strength and elongation at break) were performed. In conclusion,
the irradiated DGEBA/EPDM compounds may be used for several applications due
to the improvement in their mechanical and thermal properties. Their properties are
satisfactory for application that requires stronger material.
