Modified starch was prepared in this work by acid-thinning and oxidizing corn starch with ammonium persulfate. Also, starch-based aqueous polymer isocyanate (API) wood adhesive was prepared. The effect of the added amount of modified starch, styrene butadiene rubber (SBR), polymeric diphenylmethane diisocyanate (P-MDI), and the mass concentration of polyvinyl alcohol (PVOH) on the bonding stren...
The structure of silica particles network in two different solution styrene-butadiene rubbers (S-SBR) was studied by means of small angle x-ray scattering (SAXS) and atomic force microscopy (AFM). S-SBR compounds with different silica contents were analyzed in comparison with their oil extended counterparts. A study into the application of Small-Angle X-Ray Scattering experiments was defined in...
Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) monosulfide (TMTS) accelerators environmentally friendly plasticizers, obtained from PET recycling biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the products tested compared those commercial dioctyl terephthalate (DOTP). TMTS was prepared by simpl...
Styrene is a high production chemical; the production capacity for styrene in the United States was over 12 billion pounds in 2008. Small amounts of styrene are naturally present in foods such as legumes, beef, clams, eggs, nectarines, and spices. It can also be present in packaged foods by migration from polystyrene food containers and packaging materials. Styrene is a combustion product of ci...
The management of end-of-life tires (ELTs) is one the main environmental issues that society faces nowadays. Recycling ELTs appears as feasible option for tackling problem, although their incorporation ground tire rubber (GTR) in other matrices limited due to poor compatibility. In this research, we report a successful combination cryo-grinding process with chemical treatment modifying surface ...
Cellulose nanofibers (CNFs) are bio-sourced nanomaterials, which, after proper chemical modification, exhibit a unique ability to disperse carbon-rich micro- and nanomaterials can be used in the design of mechanically strong functional nanocomposites. When preparation graphite anodes for Li-ion batteries, they have potential outperform conventional binders such as carboxymethyl cellulose (CMC) ...
This article evaluates the impact of different fiber types on flexural creep self-compacting concretes (SCC). The study focuses effects vegetable fibers (Hemp, [H] and Dis [D]) synthetic (Polypropylene [P]) SCC. To assess SCC, various tests such as spreading, J Ring, compressive strength, strength are conducted. authors developed a test configuration methodology to subject beams measuring 120 c...
Potassium ion batteries (KIBs) are emerging notably due to the reversible K+ intercalation into graphite. So far, optimization of graphite electrode formulation remains, however, be investigated. This work thus proposes optimize ionic (porosity) and electronic percolation networks as well mechanical properties electrodes for KIBs. To do so, carbon black amount (CB) calendering is first adjusted...
OBJECTIVE This study evaluated the association between exposure to several chemicals and mortality from lymphohematopoietic cancer (LHC) among 16,579 synthetic rubber industry workers who were followed up from 1943 to 1998. METHODS Poisson regression analyses examined LHC rates in relation to butadiene, styrene, and DMDTC exposure. Models provided maximum likelihood estimates of the relative ...
