Paper material is in some contexts considered basic and unsophisticated, however designers and artists often approach the well-known material and explore the expressional value of paper craft. This work aims to investigate an alternative process of making dress, by using paper as material to interpret wearing in order to highlight the making process in the result, through the diverse properties of paper sheets and binders.  The series of examples in ‘Paper Wear’ suggests an alternative language in form and expression and the investigation has given a further understanding of dress and the importance of experimental design thinking, as well as a deeper understanding of the role of the human body in dress. The outcome of the investigation creates a tension between a well-known material used in the process of making and the finished result, challenging traditional garment conventions and how garments are perceived in relation to material, function and body.

<p>The interface between two dissimilar materials often presents a challenge for materials engineers. Mismatches of moduli, coefficients of thermal expansion, surface energies and chemical functionalities can create headaches for engineers seeking to control and understand interfacial bonding. In this work, I am interested in two specific interfacial problems: the adhesion of pressure sensitive adhesive tapes to various substrates and the interface in polymer reinforced composite materials between the reinforcement phase and the matrix.</p> <p>Pressure sensitive adhesive tapes (PSATs) are an important class of materials with applications ranging from medical adhesives to roadway markings. In this work, I present a novel 90° peel fixture to be used in the evaluation of road tapes on roadway surfaces in construction zones. This modular fixture was validated on control surfaces before demonstrating the capability to test pavement marking tapes from road surfaces. Within the context of medical adhesives, I am interested in the deformation of the skin around the PSAT during peeling. By developing a model to predict this deformation, adhesives can be tailored to mitigate skin damage. I present experimental evidence indicating the independence of peeling force to the elastic modulus of the substrate along with deformation measurements of skin analogs during the removal of a medical tape. A new model for predicting the deformation of soft substrates during peel is reported based on the contact mechanics of a rectangular prism indenting an elastic half space.</p> <p>Polymer matrix composites are another category of materials which are increasingly adopted to improve performance or efficiency by reducing the weight of components. These materials offer a high specific strength but often fail catastrophically rather than gradually. Using stress responsive fluorescent molecules called mechanophores, I present a methodology to quantify stresses within the polymeric matrix near the reinforcement phase. By correlating in situ fluorescence intensity measurements during a uniaxial tensile test to stresses predicted from a finite element analysis model, a calibration was developed. This calibration was then applied to increasingly complex composite geometries. Chemically bonding these mechanophores to the interface between two materials allows for the detection of interfacial failures through fluorescence microscopy. I present a technique to synthesize interfacial spirolactam mechanophores on industrially relevant epoxy and silica material systems. I demonstrate the ability of these systems to detect failures in the system through in situ confocal microscopy during deformation.</p>

This research provides the evaluation of the technical measurements of pavement marking materials from a two-year data collection on 2002 National Transportation Product Evaluation Program (NTPEP)?s Mississippi Test Deck from June, 2002 to June 2004. The materials studied in this research were divided into permanent and temporary material groups on two different pavement surfaces ---- asphalt and concrete. The retro reflectivity and durability of permanent marking materials among different surfaces, colors and groups were studied. Also the characteristics for temporary tapes, which include internal tape strength, adhesion, tackiness and dicernablity were compared and regressed. This correlation analysis is to see whether these ratings are correlated to each other. The results of this study can be used for estimating service lives of pavement marking materials. They also can be used by states to select appropriate pavement marking materials for different needs.

In order to increase the efficiency and economic viability of solid oxide fuel cells (SOFCs), new materials for the cathode, anode, and electrolyte of the cells must be found. SOFCs have a ceramic electrolyte, which is commonly made of fully stabilized zirconia. Due to increased material degradation rates at elevated temperatures ( ~ 1000°C) of current SOFCs, materials for the manufacture of intermediate temperature SOFCs, which operate in the range of 700-800°C, are currently under study. In this study, the manufacturing process for scandia-ceria stabilized zirconia powder (1 0mol¾ Sc2O3, lmol¾ CeO2, 89mol% ZrO2), from Daiichi Kigenso Kagaku Kogyo (DKKK) is developed, including tape casting and sintering procedures to result in pellets of high enough quality to produce single button cells. It is found that a slip prepared with about 44 wt% zirconia powder and increased proportions of solvents, dispersant, binder and plasticizers produces a favorable viscosity of about 7 40cP after deairing, and will produce tapes that are reasonably smooth and of stable thickness. Since the single cell will be structurally based upon this electrolyte material, the physical properties of the pellets are important, in addition to the electrochemical properties of the constituent materials. Tapes cast at 500µm, at 50% feed rate with a 50°C drying temperature, laminated and sintered at 1500°C on setter plates will produce flat, smooth, stiff pellets for the production of single buttons for use as the electrolyte. Cathode (50-50 mixture of La0.6Sr0_4Fe0_8Co0.2O3 + 20mol% Gd2O3 80mol% CeO2) and Anode (35 wt% DKKK powder, 65 wt% NiO) materials were hand-painted on to either side of the electrolyte and sintered to create a complete SOFC cell consisting of cathode, electrolyte, and anode.

<p dir="ltr">Good visibility of lane markings is important for all road users, particularly autonomous vehicles. In general, nighttime retroreflectivity is one of the most challenging marking visibility characteristics for agencies to monitor and maintain, particularly in cold weather climates where agency snowplows remove retroreflective material during winter operations.</p><p dir="ltr">Traditional surface-applied paint and glass beads typically only last one season in cold weather climates with routine snowplow activity. Recently, transportation agencies in cold weather climates have begun deploying improved recessed, durable pavement markings that can last several years and have very high retroreflective properties. These recessed durable markings are typically either epoxy, thermoplastic or preformed tape and are typically installed during new construction or significant pavement resurfacing projects. As a result, several dozen installations may occur in a state in any calendar year. This presents a challenge for states that need to program annual re-painting of traditional waterborne paint lines, but not paint over the much more costly durable markings.</p><p dir="ltr">This study reports on the utilization of mobile mapping LiDAR systems to classify and evaluate pavement markings along a 73-mile section of westbound I-74 in Indiana. LiDAR intensity data can be used to classify pavement markings into 3 groupings: high-performing durable tape, non-tape, and needing maintenance. RGB images collected during the LiDAR intensity data collection were used to validate the LiDAR classification. These techniques can be used by agencies to develop accurate pavement marking inventories to ensure that only painted lines (or segments with missing tape) are repainted during annual maintenance.</p>

Several types of research are ongoing throughout the world, to discover economical and reliable techniques to create hydrogen, and propagate the vision of a hydrogen economy. This research examines a COMSOL Multiphysics 5.4 heat transfer model for a hydrogen production system consisting of a retort with two different heat sources, namely a heat tape and an infrared (IR) lamp. The main objective was to compare the two heat sources and find out which one offers a better technique for producing hydrogen by raising the internal center core temperature of the retort from ambient to the highest temperature, preferably 700℃, within the shortest time possible and using less power consumption in attaining the targeted temperature. Through this study, it was established that the IR lamp could potentially help with energy savings by using just 4 kWh to reach the targeted temperature within an hour.
