  1. Microfluidic devices for drug assays

    Regnault, Clement; Dheeman, Dharmendra; Hochstetter, Axel
    In this review, we give an overview of the current state of microfluidic-based high-throughput drug assays. In this highly interdisciplinary research field, various approaches have been applied to high-throughput drug screening, including microtiter plate, droplets microfluidics as well as continuous flow, diffusion and concentration gradients-based microfluidic drug assays. Therefore, we reviewed over 100 recent publications in the field and sorted them according to their microfluidic approach. As a result, we are showcasing, comparing and discussing broadly applied approaches as well as singular promising ones that might contribute to shaping the future of this field.

  2. Organic carbon amendments for enhanced biological attenuation of trace organic contaminants in biochar-amended stormwater biofilters

    Ulrich, Bridget A.; Vignola, Marta; Edgehouse, Katelynn; Werner, David; Higgins, Christopher P.
    This study sought to evaluate how dissolved organic carbon (DOC) affects attenuation of trace organic contaminants (TOrCs) in biochar-amended stormwater biofilters. It was hypothesized that (1) DOC-augmented runoff would demonstrate enhanced TOrC biodegradation and (2) biochar-amended sand bearing DOC-cultivated biofilms would achieve enhanced TOrC attenuation due to sorptive retention and biodegradation. Microcosm and column experiments were conducted utilizing actual runoff, DOC from straw and compost, and a suite of TOrCs. Biodegradation of TOrCs in runoff was more enhanced by compost DOC than straw DOC (particularly for atrazine, prometon, benzotriazole, and fipronil). 16S rRNA gene quantification and sequencing revealed that growth-induced...

  3. Explosive detonation causes an increase in soil porosity leading to increased TNT transformation

    Yu, Holly A.; Nic Daeid, Niamh; Dawson, Lorna A.; DeTata, David A.; Lewis, Simon W.
    Explosives are a common soil contaminant at a range of sites, including explosives manufacturing plants and areas associated with landmine detonations. As many explosives are toxic and may cause adverse environmental effects, a large body of research has targeted the remediation of explosives residues in soil. Studies in this area have largely involved spiking ‘pristine’ soils using explosives solutions. Here we investigate the fate of explosives present in soils following an actual detonation process and compare this to the fate of explosives spiked into ‘pristine’ undetonated soils. We also assess the effects of the detonations on the physical properties of...

  7. Inter-industry innovations in terms of electric mobility: should firms take a look outside their industry?

    von Delft, Stephan
    The beginning electrification of the automotive powertrain is supposed to have a major impact on the automobile value chain - reshaping it significantly and bringing up new alliances, business models and knowledge bases. Such a transformation of the value chain might fade boundaries between hitherto distinct knowledge bases, technologies, or industries. Over the past decades, the blurring of industry boundaries – the phenomenon of industry convergence – has gained attention from researchers and practitioners. The anticipation of a convergence process plays an important role for strategic and innovation management decisions, e.g. for new business development, mergers and acquisitions or strategic partnerships....

  8. The importance of animal baselines: using isotope analysis to compare diet in a British medieval hospital and lay population

    Bownes, Jessica; Clarke, Leon; Buckberry, Jo
    The results of carbon and nitrogen isotope analysis from two medieval populations are presented here, in a study investigating dietary habits within a medieval hospital population in England. We used δ13C and δ15N measurements of bone collagen in order to attempt to identify a distinct group diet within the medieval hospital of St. Giles, Brough, Yorkshire, and examine the reasons why the dietary habits within the institution may have been noticeably different from that of a comparative lay population. Following the results and tentative conclusions of a study conducted by Müldner and Richards (2005), it was hypothesised that religious fasting...

  11. High-precision 41K/39K measurements by MC-ICP-MS indicate terrestrial variability of δ41K

    Morgan, Leah E.; Santiago Ramos, Danielle P.; Davidheiser-Kroll, Brett; Faithfull, John; Lloyd, Nicholas S.; Ellam, Rob M.; Higgins, John A.
    Potassium is a major component in continental crust, the fourth-most abundant cation in seawater, and a key element in biological processes. Until recently, difficulties with existing analytical techniques hindered our ability to identify natural isotopic variability of potassium isotopes in terrestrial materials. However, measurement precision has greatly improved, and a range of K isotopic compositions has now been demonstrated in natural samples. In this study, we present a new technique for high-precision measurement of K isotopic ratios using high-resolution, cold plasma multi-collector mass spectrometry. We apply this technique to demonstrate natural variability in the ratio of 41K to 39K in...

  12. Graphical statistics to explore the natural and anthropogenic processes influencing the inorganic quality of drinking water, ground water and surface water

    Flem, Belinda; Reimann, Clemens; Fabian, Karl; Birke, Manfred; Filzmoser, Peter; Banks, David
    Plots of cumulative distribution functions (CDF) are a simple but powerful exploratory data analysis (EDA) tool to evaluate and compare statistical data distributions. Here, empirical CDF plots are used to compare results of four large (476 to 884 samples) national- to continental-scale inorganic water chemistry data sets: (1) European surface water, (2) European tap water, (3) European bottled waters as a proxy for groundwater and (4) Norwegian crystalline bedrock rock groundwater, all analysed at the same laboratory, albeit at different times. For many parameters (e.g., Ba, Cl-, K, SO4 2-) median values and ranges are, given the differing origins and, in...

  20. Redox-controlled potassium intercalation into two polyaromatic hydrocarbon solids

    Romero, F. Denis; Pitcher, M.J.; Hiley, C.I.; Whitehead, G.F.S.; Kar, S.; Ganin, A.Y.; Antypov, D.; Collins, C.; Dyer, M.S.; Klupp, G.; Colman, R.H.; Prassides, K.; Rosseinsky, M.J.
    Alkali metal intercalation into polyaromatic hydrocarbons (PAHs) has been studied intensely after reports of superconductivity in a number of potassium- and rubidium-intercalated materials. There are, however, no reported crystal structures to inform our understanding of the chemistry and physics because of the complex reactivity of PAHs with strong reducing agents at high temperature. Here we present the synthesis of crystalline K2Pentacene and K2Picene by a solid–solid insertion protocol that uses potassium hydride as a redox-controlled reducing agent to access the PAH dianions, and so enables the determination of their crystal structures. In both cases, the inserted cations expand the parent...
