world’s largest generators of pollution (Hershkowitz 1 of 10). Paper mills contaminate rivers, produce air and water pollutants, and contribute to producing smog (Hershkowitz 1 of 10). As Sam Martin points out, “Compared to making paper from virgin materials, however, recycling is clearly more responsible to the environment” (Martin 3 of 7). Recycling aluminum cans uses only five percent of the energy needed to produce new aluminum cans (“Recycling” 2 of 2). About sixty-nine percent of the…

A concrete patio or entryway is a standard on most homes in Texas. Owners don’t typically even acknowledge that they can transform this feature of their home although it’s typically the first thing a visitor sees. A concrete overlay is a cost efficient way to add style and a modern touch to the front of a home to boost its curb appeal. A concrete overlay is an ideal way to transform any concrete feature that needs a little style. A front porch or entryway is typically just plain concrete with a…

attributing to the presence of ZIF-67 nanoparticles, acting as the crosslinkers, enhancing the interactions between the cellulosic molecular chains. The determination of mechanical properties under wet condition is of great significance to the paper-based materials. As shown in Fig. 3(C) and Table S3, the CP under wet condition had poor mechanical properties with tensile strength and elastic modulus of 0.15 and 22 MPa , respectively. In contrast, the CP/CNF showed favorable mechanical…

Beyond The Spotlight: The Misrepresentation of Women TLC’s original music video, “Unpretty” and Susan Bordo’s essay, “Material Girl” critiques the way women portray themselves by society’s definition of beauty. Women will compete for their spouse’s attention against other females with sexually, idolized bodies because they feel they lack certain aspects. Women must learn to love themselves before they…

the beginning of human history, people have strived to come up with ways to easily access this life-sustaining liquid. During the height of the Roman Empire, aqueducts were erected to distribute water to the cities, and containers made from clay, materials of natural fibers, and animal pelts were utilised to carry water in less significant amounts. Thousands of years later, water began to be sold in glass bottles, and that soon…

These are similar to mineral component that present in bones and hard tissues (Ilie et al., 2016). The combination of ceramic based materials - hydroxyapatite and natural polymer as sodium alginate will provide strength, stiffness and fracture toughness to bone (S. Lala et al., 2016). The composite materials have been used in load bearing application such as filler and bone defect. Alginate (Alg) is a natural polymer which synthesized from brown algae. Alginate is more…

The lattice symmetry of quartz α-FePO4 is trigonal. Its space group is P3121. The lattice symmetry of quartz β-FePO4 is hexagonal. It space group is P6422. According to the article, only two of the various quartz homeotypes which exhibit alpha-beta transitions have been studied in detail at high temperature. One of them is Silicon Dioxide. As such, it is possible for silicon dioxide to have the same structure when the chemistry is completely different. Since iron…

nonpathogenic aerobic bacteria in a culture medium containing carbon and nitrogen sources can be promising biodegradable nanofibers for composite materials because of their excellent mechanical properties [1]. Although BC is chemically identical to plant-based cellulose, it exists in extremely pure form and does not contain any hemicellulose, lignin, pectin or wax materials [2]. In addition, it has higher crystallinity, degree of polymerization, specific surface area, and significantly higher…

poems, “The World is too Much with Us,” written in the 1800s and “Spirits in the Material World” which was written in 1981. The poems are both in response to the everchanging world. These poems use specific poetic elements to create force behind their arguments. Furthermore, each poem conveys a similar theme that materialism is going to ruin the planet for future generations. The first poem “Spirits in the Material World,” has five stanzas and utilizes many poetic elements such as repetition…

Some states are already creating strict laws. Rhode Island has created a law that says 80% of packaging that businesses use must be recycled (In the Bin). I think that sets a good example for the other countries and we should have similar laws. The only measly law that Missouri has is “It is illegal to discard a motor vehicle battery of other lead-acid battery” (recycling Laws Map). This is a step in the right direction, but it still is not good enough. We need better and stricter laws, and…
