    The Effects of Surfactant Pretreatment and Xylooligomers on Enzymatic Hydrolysis of Cellulose and Pretreated Biomass (2010)

    Content: There is a vital need to reduce enzyme costs to facilitate production of cost-competitive cellulosic ethanol and other products. End-product inhibition, declining substrate reactivity, enzyme denaturation, and non-productive binding of enzyme to lignin are among the factors that could account for the loss of enzyme effectiveness as enzymatic hydrolysis of lignocellulosic biomass proceeds. In addition, lignin and hemicelluloses, the other two most abundant components in lignocellulosic biomass besides cellulose, are believed to be responsible for high recalcitrance of lignocellulosic biomass to biological conversion. This study focused on investigating the effects of hemicelluloses on enzymatic hydrolysis and developing possible strategies to overcome their negative impacts. In the first part of the study, we identified that xylooligomers released from biomass during pretreatment and enzymatic hydrolysis are stronger inhibitors than long known for glucose and cellobiose. Furthermore, mixtures of xylooligomers of varying chain length were shown to dramatically decrease enzymatic conversion rates and yields of both pure cellulose and pretreated biomass. To clarify the relative importance of different xylooligomers, gel permeation chromatography (GPC) was applied to separate xylooligomers according to their chain length, and selected fractions were added to pure cellulose hydrolysis to determine their relative influence on rates and yields. The degree of inhibition was found to increase with xylooligomer degree of polymerization (DP), and cellulase exhibited a greater binding affinity for birchwood xylan than pure cellulose. All of these observations suggest that xylooligomers could competitively adsorb on cellulase, thereby reducing enzyme accessibility to cellulose and cellooligomers. Consequently, applying hemicellulase to hydrolyze xylooligomers to much less inhibitory xylose prior to adding cellulase reduced this undesirable binding and was more beneficial than adding hemicellulase and cellulase together.

    Intertemporal Trust Game (2021)

    Content: We experimentally investigate the effect of timing of implementation of decisions on trust and trustworthiness. In the “Now” treatment, a standard trust game is run and subjects receive payment in the same date of the experiment. In the “Later” treatment, subjects make decisions in the same date as the now treatment, while the decisions are implemented (and hence payment) in a week. The later treatment captures a key feature of social interactions where decisions are often implemented in the future rather than immediately. Consistent with our model, we find that both trust and trustworthiness are lower in the later treatment. Our result thus suggests that individuals who discount utility from altruism to a larger extent than utility from monetary payoff will have less incentive to trust or be trustworthy when the decision is implemented with a delay

    Should Firms Use Both Prosocial Incentives and Monetary Incentives to Motivate Workers? (2019)

    Content: This paper experimentally investigates whether firms should use both prosocial incentives and monetary incentives to motivate workers. We conduct a real-effort experiment on a data entry job. It is found that prosocial incentives will likely reduce work quality. When worker's compensation does not include prosocial incentives, making the compensation conditional on the quality of work performed greatly enhanced the work quality. However, when worker's compensation includes prosocial incentive, making the compensation conditional on the work quality no longer improve work quality. This suggests that prosocial incentive induces some workers to work less professionally

    Nanocellulose: Preparation, Characterization, Supramolecular Modeling, and its Life Cycle Assessment (2012)
    [Erscheinungsort nicht ermittelbar] : Virginia Tech

    Content: Nanocellulose is a nascent and promising material with many exceptional properties and a broad spectrum of potential applications; hence, it has drawn increasing research interests in the past decade. A new type of nanocellulose -- with mono- or bi-layer cellulose molecular sheet thickness -- was synthesized through a combined chemical-mechanical process (TEMPO-mediated oxidation followed by intensive sonication), and this new material was named molecularly thin nanocellulose (MT nanocellulose). The overarching objective of this study was to understand the formation and supramolecular structure of MT nanocellulose and contribute to the knowledge of native cellulose structure. The research involved four major bodies of study: preparation of MT nanocellulose, characterization of MT nanocellulose, modeling wood pulp-derived cellulose microfibril cross section structure, and a comparative life cycle assessment (LCA) of different nanocellulose fabrication approaches. The results revealed that MT nanocellulose with mono- to bi-layer sheet thickness (~0.4-0.8 nm), three to six chain width (~2-5 nm), and hundreds of nanometers to several microns length, can be prepared through TEMPO-mediated oxidation followed by 5-240 min intensive sonication. The thickness, width, and length of MT nanocellulose all decreased with extended sonication time and leveled off after 1 or 2 h sonication. Crystallinity, hydrogen bonding, and glycosidic torsion angles were evaluated by XRD, FTIR, Raman, and NMR. These experiments revealed systematic changes to structure with sonication treatments. A microfibril cross section triangle scheme" was developed for the microfibril supramolecular modeling process and a 24-chain hexagonal/elliptical hybrid model was proposed as the most credible representation of the supramolecular arrangement for wood pulp-derived cellulose I" microfibril. Comparative LCA of the fabrication of nanocellulose indicated that nanocellulose presented a significant environmental burden markup on its precursor, kraft pulp, and the environmental hotspot was attributed to the mechanical disintegration process. Yet, overall nanocellulose still presented a prominent environmental advantage over other nanomaterials like single-walled carbon nanotubes, due to its relative low energy consumption. Overall, this research developed a facile approach to produce a new type of nanocellulose, the MT nanocellulose, provided new insights about the supramolecular structure of cellulose microfibrils, and evaluated the environmental aspects of the fabrication process of nanocellulose.

    A Horse Race of Preferences for Predicting Portfolio Choice (2021)
    [S.l.] : SSRN

    Format: 1 Online-Ressource (64 p)
    Content: We conduct a horse race of preferences to compare the predictive power and net effects of 15 types of preferences, such as attention, ambiguity aversion, loss aversion, probability overweighting, time preference, confidence, self-control, trust, and strategic reasoning, on actual investment decisions and outcomes. We estimate the net effects of the preferences by considering the correlations between the preferences. We find that for share of wealth invested in the stock market, the effect of confidence (Kyle and Wang, 1997) is stronger than that of risk aversion, which is stronger than the effects of self-control (Heidhues and Koszegi, 2010), loss aversion (Tversky and Kahneman, 1992), and ambiguity aversion (Dow and Werlang, 1992). For holding lottery-like stock, the effect of attention (Sims, 2003) is stronger than that of the discount rate, which is stronger than that of probability overweighting (Barberis and Huang, 2008). For share of lottery-like stock, the effect of strategic reasoning (Nagel, 1995) is stronger than that of probability overweighting. For wealth level, self-control has the strongest net effect
