Zinc and Cadmium in Paper (Reaffirmation of T 438 Cm-96)
WI 050114.01 T 438 DRAFT NO. 5 DATE July 27, 2006 TAPPI WORKING GROUP CHAIRMAN J Ishley SUBJECT CATEGORY Fillers & Pigments Testing RELATED METHODS See “Additional Information” CAUTION: This Test Method may include safety precautions which are believed to be appropriate at the time of publication of the method. The intent of these is to alert the user of the method to safety issues related to such use. The user is responsible for determining that the safety precautions are complete and are appropriate to their use of the method, and for ensuring that suitable safety practices have not changed since publication of the method. This method may require the use, disposal, or both, of chemicals which may present serious health hazards to humans. Procedures for the handling of such substances are set forth on Material Safety Data Sheets which must be developed by all manufacturers and importers of potentially hazardous chemicals and maintained by all distributors of potentially hazardous chemicals. Prior to the use of this method, the user must determine whether any of the chemicals to be used or disposed of are potentially hazardous and, if so, must follow strictly the procedures specified by both the manufacturer, as well as local, state, and federal authorities for safe use and disposal of these chemicals. Zinc and cadmium in paper (Reaffirmation of T 438 cm-96) (no changes were made since last draft) 1. Scope and significance 1.1 This method maybe used for the determination of cadmium and zinc either in paper or in highly opaque pigments. Zinc is usually present in zinc oxide, zinc sulfide, or as lithopone (a combination of zinc sulfide and barium sulfate), which is occasionally used in filled paper, in paper coatings and in high-pressure laminates and wallpaper. -
Single Pass Cooling Systems
A Sustainable Alternative to Single Pass Cooling Systems Amorette Getty, PhD Co-Director, LabRATS What is Single Pass Cooling? ● Used for distillation/reflux condensers, ice maker condensers, autoclaves, cage washers… ● Use a continuous flow of water from faucet to sewer o 0.25-2 gallons per minute, o up to 1,000,000 gallons of water/year if left on continuously Single Pass Cooling: Support ● “U.S. Environmental Protection Agency has ranked the elimination of single-pass cooling systems #4 on its list of top ten water management techniques” -Steve Buratto, Chair of Chemistry and Biochemistry department NOT Just a Sustainability Issue! California Nanosystems Institute (CNSI) flood in a second-floor laboratory in July, 2014. Water ran at ~1-2 gallons per minute for 6-10 hours, overflowing into a ground floor electron microscopy lab CNSI Flood Losses ● $ 2.2 Million in custom built research equipment ● Research shutdown for 4 months ● over 200 hours of staff time ● Insurance no longer covering this type of incident again Campus Responses to the Incident • CNSI ban on single pass cooling systems • TGIF grant financial incentive for optional change of single replacement systems • Chemistry and Material Research Laboratory (MRL) • Additional Grants being sought • Conversation at Campus and UC-level to regulate and replace these types of systems. Seeking Allies… ● “The replacement of single-pass cooling systems with closed-loop and water free systems would save water and represent a major advance in the sustainability efforts of the campus.” -Steve Buratto, Chair of Chemistry and Biochemistry department Barriers to Replacement ● “...major obstacle to replacing the single-pass cooling systems with closed-loop and water- free systems is cost. -

Abstract Hydrogen is seen as a potential fuel for the future; its choice is driven by the increasing awareness of the necessity for clean fuel. Together with the simultaneous development of “green technologies” and sustainable development, a current goal is to convert waste to energy or to create energy from a renewable resource. Biological processing [of renewables] or bioremediation of waste to create hydrogen as a product fulfils this goal and, as such, is widely researched. In this work, an already established process, using a hydrogenase up‐regulated strain ‐ was characterised and the important process parameters were established. This bacterial strain has the potential for industrial‐scale hydrogen production from, for example, waste sugars. Previous work, repeated here, showed that hydrogen could be generated by E. -

Hydrofluoric acid vapors or baths of hydrofluoric acid salts may be used to give glass a matte, frosted appearance (similar to that obtained by surface sandblasting), as found in lighting glass. Glass designs can be produced by coating the glass with wax and then inscribing the desired pattern through the wax layer. When applied, the acid will corrode the glass but not attack the wax-covered areas. Alumina-silicate Glass Alumina (aluminum oxide Al2O3) is added to the glass batch in the form of commonly found feldspars containing alkalis in order to help improve chemical resistance and mechanical strength, and to increase viscosity at lower temperatures. Angle of Incidence The angle formed between a ray of light striking a surface and the normal line (the line perpendicular to the surface at that point). Annealing Under natural conditions, the surface of molten glass will cool more rapidly than the center. This results in internal stress- es which may cause the glass sheet or object to crack, shatter or even explode some time later. The annealing process is designed to eliminate or limit such stresses by submitting the glass to strictly controlled cooling in a special oven known as a “lehr”. Inside the lehr, the glass is allowed to cool to a temperature known as the “annealing point”. -

The Pennsylvania State University The Graduate School ADVENTURES IN HIGH DIMENSIONS: UNDERSTANDING GLASS FOR THE 21ST CENTURY A Dissertation in Material Science and Engineering by Collin James Wilkinson © 2021 Collin James Wilkinson Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy May 2021 ii The dissertation of Collin Wilkinson was reviewed and approved by the following: John Mauro Professor of Materials Science and Engineering Chair, Intercollege Graduate Degree Program Associate Head for Graduate Education, Materials Science and Engineering Dissertation Advisor Chair of Committee Seong Kim Professor of Chemical Engineering Professor of Materials Science and Engineering Ismaila Dabo Associate Professor of Materials Science and Engineering Susan Sinnott Professor of Materials Science and Engineering Professor of Chemistry Head of the Department of Materials Science and Engineering iii Abstract Glass is infinitely variable. This complexity stands as a promising technology for the 21st century since the need for environmentally friendly materials has reached a critical point due to climate change. However, such a wide range of variability makes new glass compositions difficult to design. The difficulty is only exaggerated when considering that not only is there an infinite variability in the compositional space, but also an infinite variability thermal history of a glass and in the crystallinity of glass-cearmics. This means that even for a simple binary glass there are at least 3 dimensions that have to be optimized. To resolve this difficulty, it is shown that energy landscapes can capture all three sets of complexity (composition, thermal history, and crystallinity). The explicit energy landscape optimization, however, has a large computational cost.
