Efficacy of chitosan emulsion, salicylic acid (SA) or oxalic acid (OA) alone and chitosan loaded with SA or OA on ethylene production, extending storage life and maintenance of climacteric (nectarine and plum) and non-climacteric fruit (sweet orange) quality at ambient temperature and cold conditions was investigated.…
Correction for ‘Computational and experimental investigation of TmAgTe 2 and XYZ 2 compounds, a new group of thermoelectric materials identified by first-principles high-throughput screening’ by Hong Zhu et al. , J. Mater. Chem. C , 2015, 3 , 10554–10565.
Thermal barrier coatings (TBCs) are refractory materials deposited on gas turbine components, which provide thermal protection for metallic components at operating conditions. The current state-of-art TBC material is yttria-stabilized zirconia (YSZ), whose service temperature is limited to 1200 celsius, due to sinteri…
In the search for a new material for solar cells, the quaternary chalcogenide copper zinc tin sulde (Cu2ZnSnS4 or CZTS) is one potential candidate. It is abundant, environmentally-friendly, inexpensive, and presently it has a mediocre record effciency of around 10% with potential to reach above 15%. This thesis is a p…
Argonne National Laboratory (Argonne) developed a superabsorbing gel-based process (SuperGel) for the decontamination of cesium from concrete and other porous building materials. Here, we report on results that tested the gel decontamination technology on specific concrete and ceramic formulations from a coastal city…
The environmental conditions created in the Southwestern deserts of the United States are conducive to the production of green microalgae biomass, for use as a feedstock intended for conversion to carbon neutral liquid biodiesel. One promising heat-tolerant, rapidly-growing, high lipid content species is the chlorophy…
Die effektiven Materialeigenschaften von mikrogerissenen porösen Materialien wie zementgebundene Materialien, Gestein und Keramik hängen stark von der Komplexität der Mikrostruktur ab. In dieser Dissertation, analytischen und semi-analytischen Mikromechanik Modelle sind entwickelt und in Zusammenhang mit Direkt Numeri…
Telah dilakukan penelitian yang berjudul Pengaruh Komposisi pada Sifat Struktur dan Superkonduktivitas Fe(Se,Te) Dipreparasi dengan Metode Metalurgi Serbuk. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh parameter komposisi stoikiometri terhadap sifat struktur dan superkonduktivitas Fe(Se,Te) sehingga dap…
Für die prozesssichere Anwendung des Laserstrahl-Mikroschweißens im industriellen Umfeld ist die Kenntnis des Prozesses von immanenter Bedeutung. Daher wird in vorliegender Arbeit der Laserstrahl-Mikroschweißprozess anhand von metallischen Folien systematisch charakterisiert. Während des Laserstrahl-Mikroschweißens vo…
Oxyborate minerals can represent the most important sink for boron in silica-undersaturated mineralised systems such as those of the Långban-type. Yet, their distribution, characteristics and parageneses are still not completely known. In order to test the hypothesis that the chemical compositions of oxyborates are es…
Previous work in this field of research has proven that the intrinsic properties of native starch can be modified to have desirable traits. For example there are two widely researched natural properties of native starch: physically brittle and hydrophilic. Researchers have been successful at mixing native starch with…
This dissertation describes the catalytic upgrading of phenolic compounds over ceria-based materials. The work was motivated by the need to find alternative industrial uses for the light rare earth elements (e.g. cerium) as part of the Critical Materials Institute. Cerium is typically encountered in the +3 or +4 oxida…
Daguerreotypes, nineteenth century photographs made entirely of metal, tarnish easily when exposed to atmosphere or other corrosive environments. The removal of such corrosion products has always been a controversial issue due to the irreversibility and potential damage inflicted by the treatment process. When perform…
Chronic non-healing wounds (e.g., diabetic foot ulcers and bed sores) impact over 6.5 million Americans per year, costs in excess of $25 billion to treat on an annual basis, and are on the rise due to increasing levels of obesity and diabetes compounded by an aging population. A major inhibitor of healing is suboptima…
Corrosion in geological disposal facilities of high level nuclear waste is of great importance to maintain the integrity of the waste container and thus ensure the public safety. Specifically, a nuclear waste “Supercontainer” has been designed by Belgium with carbon steel as being the main metallic barrier material. T…
In order to meet the goal of reducing CO2 emissions, automotive industry places significant importance on downsizing components to achieve greater efficiency through lower weight and reduced friction. As friction reductions are associated with energy efficiency and wear protection with resource conservation, ever grea…
Titanium alloys are increasingly becoming the material of choice for a wide range of applications. They have found their way into aerospace, biomedical and automotive industries due to their superior properties such as good strength-to-weight ratio, high corrosion resistance and bio-compatibility. However, machining o…
The present work is concerned with the advancement of the relatively recent class of local hybrid functionals. The first part of the work addresses the conjunction of local hybrid functionals with linear-response time-dependent density functional theory (TDDFT), which is the most widely used quantum chemical method fo…
This thesis is concerned with a phase field model for martensitic transformations in metastable austenitic steels. Within the phase field approach an order parameter is introduced to indicate whether the present phase is austenite or martensite. The evolving microstructure is described by the evolution of the order pa…
Critical exploration of the minimalistic high strength low alloy aluminum (HSLA-Al) paradigm is necessary for the continued development of advanced aluminum alloys. In this study, scandium (Sc) and zirconium (Zr) are examined as the main precipitation strengthening additions, while magnesium (Mg) is added to probe the…
