Molecular Probe Dynamics Reveals Suppression of Ice-Like Regions in Strongly Confined Supercooled Water
No full textThe structure of the hydrogen bond network is a key element for understanding water's thermodynamic and kinetic anomalies. While ambient water is strongly believed to be a uniform, continuous hydrogen-bonded liquid, there is growing consensus that supercooled water is better described in terms of distinct domains with either a low-density ice-like structure or a high-density disordered one. We evidenced two distinct rotational mobilities of probe molecules in interstitial supercooled water of polycrystalline ice [Banerjee D, et al. (2009) ESR evidence for 2 coexisting liquid phases in deeply supercooled bulk water. Proc Natl Acad Sci USA 106: 11448-11453]. Here we show that, by increasing the confinement of interstitial water, the mobility of probe molecules, surprisingly, increases. We argue that loose confinement allows the presence of ice-like regions in supercooled water, whereas a tighter confinement yields the suppression of this ordered fraction and leads to higher fluidity. Compelling evidence of the presence of ice-like regions is provided by the probe orientational entropy barrier which is set, through hydrogen bonding, by the configuration of the surrounding water molecules and yields a direct measure of the configurational entropy of the same. We find that, under loose confinement of supercooled water, the entropy barrier surmounted by the slower probe fraction exceeds that of equilibrium water by the melting entropy of ice, whereas no increase of the barrier is observed under stronger confinement. The lower limit of metastability of supercooled water is discussed
Food for nought
No full textThe short story, "Food for nought", is written by the listed author above, Shashi Bhat. Now in its 48th year, Best Canadian Stories has long championed the short story form and highlighted the work of many of the writers, throughout their respective careers, who have gone on to shape the Canadian literary canon. Caroline Adderson, Margaret Atwood, Clark Blaise, Lynn Coady, Mavis Gallant, Zsuzsi Gartner, Douglas Glover, Steven Heighton, Isabel Huggan, Mark Anthony Jarman, Norman Levine, Rohinton Mistry, Alice Munro, Leon Rooke, Diane Schoemperlen, Russell Smith, Linda Svendsen, Kathleen Winter, and many others have appeared in its pages over the years and decades, making Best Canadian Stories the go-to source for what’s new in Canadian fiction writing for close to five decades. A continuation of not only a series, but a legacy in Canadian letters. --From publisher description.Published
ESR evidence for 2 coexisting liquid phases in deeply supercooled bulk water
No full textUsing electron spin resonance spectroscopy (ESR), we measure the rotational mobility of probe molecules highly diluted in deeply supercooled bulk water and negligibly constrained by the possible ice fraction. The mobility increases above the putative glass transition temperature of water, T(g) = 136 K, and smoothly connects to the thermodynamically stable region by traversing the so called "no man's land" (the range 150-235 K), where it is believed that the homogeneous nucleation of ice suppresses the liquid water. Two coexisting fractions of the probe molecules are evidenced. The 2 fractions exhibit different mobility and fragility; the slower one is thermally activated (low fragility) and is larger at low temperatures below a fragile-to-strong dynamic cross-over at approximate to 225 K. The reorientation of the probe molecules decouples from the viscosity below approximate to 225 K. The translational diffusion of water exhibits a corresponding decoupling at the same temperature [Chen S-H, et al. (2006) The violation of the Stokes-Einstein relation in supercooled water. Proc Natl Acad Sci USA 103:12974-12978]. The present findings are consistent with key issues concerning both the statics and the dynamics of supercooled water, namely the large structural fluctuations [Poole PH, Sciortino F, Essmann U, Stanley HE (1992) Phase behavior of metastable water. Nature 360: 324-328] and the fragile-to-strong dynamic cross-over at approximate to 228 K [Ito K, Moynihan CT, Angell CA (1999) Thermodynamic determination of fragility in liquids and a fragile-tostrong liquid transition in water. Nature 398: 492-494]
Pseudomonodictys Doilom, Ariyaw., Bhat & K. D. Hyde
No full textPseudomonodictys Doilom, Ariyaw., Bhat & K.D. Hyde, Fungal Diversity 75, 88 (2015) Saprobic on dead wood in freshwater or terrestrial habitats. Sexual morph: Ascomata solitary, scattered, semi-immersed to erumpent, visible as raised, globose to subglobose, black, ostiolate. Ostiole short papillate, with an irregular porelike opening, brown to dark brown. Peridium composed of several layers of brown to dark brown cells of textura agularis, merged with the host tissues. Hamathecium composed of dense, filamentous, branched, septate, hyaline, cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, clavate, short pedicellate, apically rounded, with an ocular chamber. Ascospores overlapping, 2–3-seriate, fusiform to cylindrical with round ends, slightly curved, multi septate, strongly constricted at the septa, narrow towards the both ends, enlarged at the middle cells, smooth-walled, hyaline, with small guttules, surrounded by a distinct, thick, mucilaginous sheath. Asexual morph: See Ariyawansa et al (2015). Notes: Pseudomonodictys was known only from its asexual morph and the characteristics of sexual morph were unknown. In this study, we reported a sexual species Pseudomonodictys aquatica based on phylogenetic evidences. Pseudomonodictys clustered with Aquastroma, Lonicericola, Multilocularia, Paramonodictys and Paratrimmatostroma in Parabambusicolaceae (FIGURE 1). Morphologically, Pseudomonodictys is similar to the sexual genera Aquastroma, Lonicericola and Multilocularia in having clavate asci with an ocular chamber and fusiform to vermiform, multiseptate ascospores with an entire sheath. However, Pseudomonodictys can be distinguished from Aquastroma and Multilocularia by the ascospores. Ascospores of Pseudomonodictys are 2–3-seriate, fusiform to cylindrical with round ends, strongly constrict at the septa and enlarged at the middle cells. While, ascospores of Aquastroma are clavate to fusiform, with a supramedian primary septum, slightly constricted at septa (Tanaka et al. 2015) and Multilocularia has 1–2-seriate, ellipsoidal ascospores which are slightly constricted at the central septum (Li et al. 2016). Pseudomonodictys is different from the asexual genera Paramonodictys and Paratrimmatostrom in having muriform, top-shaped, reddish-brown to dark brown conidia with a protruding basal cell; truncate to slightly rounded at the base. The conidia of Paramonodictys are globose or subglobose, olivaceous brown to dark brown, broadly rounded at apex whereas Paratrimmatostrom has helicoid, cylindrical, sigmoid, or reniform conidia.Published as part of Bao, Dan-Feng, Hongsanan, Sinang, Hyde, Kevin D., Luo, Zong-Long & Nalumpang, Sarunya, 2022, Pseudomonodictys aquatica sp. nov., the sexual morph of Pseudomonodictys from freshwater habitats, pp. 222-232 in Phytotaxa 567 (3) on pages 226-227, DOI: 10.11646/phytotaxa.567.3.2, http://zenodo.org/record/715667
