“…Wong and Yu [27] reported a simple protocol to prepare superhydrophobic and hydrophobic glass by treating standard microscope slides with methyltrichlorosilane and octadecyltrichlorosilane, respectively as shown in Figure 2a. Octadecyltrichlorosilane formed a closely packed, methyl-terminated, self-assembled monolayer that changed the glass surface from hydrophilic to hydrophobic (Figure 2b).…”

Transparent liquid repellent coatings with exceptional wear and abrasion resistance are very demanding to fabricate. The most important reason for this is the fact that majority of the transparent liquid repellent coatings have so far been fabricated by nanoparticle assembly on surfaces in the form of films. These films or coatings demonstrate relatively poor substrate adhesion and rubbing induced wear resistance compared to polymer-based transparent hydrophobic coatings. However, recent advances reported in the literature indicate that considerable progress has now been made towards formulating and applying transparent, hydrophobic and even oleophobic coatings onto various substrates which can withstand certain degree of mechanical abrasion. This is considered to be very promising for anti-graffiti coatings or treatments since they require resistance to wear abrasion. Therefore, this review intends to highlight the state-of-the-art on materials and techniques that are used to fabricate wear resistant liquid repellent transparent coatings so that researchers can assess various aptitudes and limitations related to translating some of these technologies to large scale stain repellent outdoor applications.

Nanoscience seems to be a main topic of this century. The chemical fundamentals are very old and named colloids since Graham in 1861. The acronym nano has been introduced in 1960 at a conference of measures and weights in Paris. In 1982 Binnig and Rohrer invented the scanning tunnel microscope(STM) and four years later Binnig the atomic force microscope(AFM). These microscopes are the main tools for the nanotechnology and from this times the number of publications exploded. In this article we'll focus on the chemical aspects of nanotechnology and how to implement experiments into school.

Nanoscale science activities are filtering into K-12 classrooms in part due to modern technological advances in the areas of healthcare, electronics, and renewable energy. These industries benefit from scientists who possess a deep understanding of science at the nanoscale and it is well known the United States needs to increase its STEM educated workforce to stay globally competitive. Nano-related activities can be effective in motivating students to pursue careers in engineering and technological fields, but at the same time they are useful in helping to pinpoint common misconceptions that exist in K-12 science classrooms. In this study, an inquiry-based lesson on the topic of surface wettability was implemented in three magnet high school classrooms. Students were asked to measure the contact angle of a water droplet on transparent glass surfaces with varying degrees of wettability (hydrophilic, hydrophobic and superhydrophobic). Based on their observations and angle measurements students were asked to write a description and make a sketch of what they thought the surface structure would look like under a microscope. Qualitative analysis was done to analyze students' drawings and written descriptions. Students' responses were grouped into topics to identify patterns related to the high school curriculum taught in chemistry, biology and physical science.Most students determined the surface coatings were different enough from each other to cause the water droplets to either bead up or spread out on the surface. The drawings of what the coating structure would look like under a microscope were varied but some depicted atomic level repulsive/attractive forces surrounding the water droplet. This highlights a common misconception about what can actually be seen and not seen under a microscope. Students also repeatedly attributed the shape of the droplet to positive/negative charges rather than surface tension. This can possibly relate to not comprehending the existence of varying length scales between the atomic and macro scales. In summary, the presentation will discuss how inquirybased activities on the topic of nanoscale science can serve to identify misconceptions in science classrooms and guide instruction in this area.
