title: Mineral-catalyzed formation of marine NO and N2O on the anoxic early Earth

description: Microbial denitrification converts fixed nitrogen species into gases in extant oceans. However, it is unclear how such transformations occurred within the early nitrogen cycle of the Archean. Here we present experimental anoxic surface-catalyzed reduction of nitrite and nitrate via green rust and magnetite combined with diffusion and photochemical modeling. We find that in a Fe2+-rich marine environment, Fe minerals could have catalyzed abiotic denitrification reactions leading to the formation of nitric oxide (NO) and nitrous oxide (N2O). Nitrate did not exhibit reactivity in the presence of either mineral or aqueous Fe2+, however, both minerals induced rapid nitrite reduction to NO and N2O. While N2O escaped into the atmosphere (63% of nitrite-nitrogen, with green rust as catalyst), NO remained associated with precipitates (7%) serving as a potential shuttle to the benthic ocean. The modeling suggests that marine N2O emissions would have sustained 0.8-6 ppb of atmospheric N2O without a protective ozone layer. Our findings add detail to the as yet incompletely documented Archean nitrogen cycle, implying a globally distributed process driven by chemical kinetics similar to those of modern enzymatically mediated conversions.

title: Eye Fitting Straight Lines in the Modern Era

description: How do statistical regression results compare to intuitive, visually fitted results? Fitting lines by eye through a set of points has been explored since the 20th century. Common methods of fitting trends by eye involve maneuvering a string, black thread, or ruler until the fit is suitable, then drawing the line through the set of points. In 2015, the New York Times introduced an interactive feature, called “You Draw It,” where readers were asked to input their own assumptions about various metrics and compare how these assumptions relate to reality. In this article, we validate “You Draw It” as a method for graphical testing, comparing results to the less technological method used in Mosteller et al. and extending that study with formal statistical analysis methods. Results were consistent with those found in the previous study; when shown points following a linear trend, participants tended to fit the slope of the principal axis over the slope of the least-squares regression line. This trend was most prominent when shown data simulated with larger variances. This study reinforces the differences between intuitive visual model fitting and statistical model fitting, providing information about human perception as it relates to the use of statistical graphics. Supplementary materials for this article are available online.

title: Effect of Application of Selective UV-absorbers/antioxidants on Raw and Bleached Jute Fabrics by Pad-batch-dry Process for Reduction of Its Photo-degradation and Photo-yellowing Character

description: To reduce photo-fading of jute, raw and H<sub>2</sub>O<sub>2</sub> bleached jute fabrics have been treated with selective UV-absorbers and antioxidant compounds by pad-batch-dry technique and subjected to photo-exposure in a weather-o-meter for different hours (0–320 h). The corresponding changes in tensile strength and the rate of reduction in whiteness index and rate of increase in yellowness index with consequent changes in <i>K/S</i> value have been evaluated. Among the selected UV-absorbers and antioxidants, sodium azide and LTDP offer good stability against photo-fading, but these treatments are not fast to washing. On the other hand, 1% benztriazole treatment gives medium to good level of resistance against photo-yellowing with reasonable wash fastness. Two percent benztriazole is applied on jute fabric by the pad-batch-dry technique in acidic media (with acetic acid) shows higher stabilization of whiteness retention (i.e. lesser extent of photo-yellowing) under UV-light exposure than other UV-absorbers/antioxidants though is associated with some small loss in tensile strength. The mechanism of possible interaction between benztriazole and major jute constituents has also been established by comparing the reaction with similar model compound (benzaldehyde) in place of reaction between jute–-hemi-cellulose–CHO and benztriazole. UV–VIS spectrophotometric and FTIR analysis undertaken made to support the said reaction mechanism.

title: The Use of the Artificial Neural Network (ANN) for Modeling of Thermogravimetric Curves of Tobacco Stalk Waste Exposed to Alkaline Treatment

description: Tobacco is a rich source of cellulosic material and one of the most cultivated non-food plants in the world with great potential for incorporation in polymeric matrices. The use of tobacco residues as reinforcing filler requires chemical/physical fiber treatment aiming to maximize compatibility with the polymer. In this study, tobacco residues were treated with two concentrations of NaOH (10 or 15 wt.%) at two-time exposures (3 or 5 h). Four distinct heating rates were used for each condition. It was applied an artificial neural network to model the thermogravimetric curves. After, the fitted ANN curves were used to create a 3D surface response. The equations from 3D surface response allowed the creation of thermogravimetric curves in any heating rate situated between the minimum and maximum range tested.

title: Superoleophilic-Hydrophobic Kapok Oil Sorbents via Energy Efficient Carbonization

description: High oil sorption, dynamic oil/water selectivity and oil retention are essential for advanced materials to remediate offshore oil spills. In this context, superoleophilic-hydrophobic kapok bundles, synthesized via a simple, one-step and energy efficient carbonization (300°C), were investigated as effective oil sorbents. It was shown that the surface roughness and intrinsic graphite phase of the kapok bundles were tunable by varying the carbonization temperature, thereby enhancing their oil sorption and retention. Lumen preservation enables the carbonaceous kapok bundles to exhibit tunable oil sorption capacities of 34.0 g/g – 95.5 g/g for various types of oil, unrivaled among other oil spill recovery methods. The origin of oil permeability into lumen is attributed to nanopores observed for the first time on the carbonaceous kapok fibers. The kapok bundles selectively absorbed oil slick under vigorous water vortex and demonstrated distinctly high oil retention of 100% under gravitation force. Multiple oil sorption-desorption and compression cycles (up to 15 times) demonstrate a considerable promise of the carbonaceous kapok bundles for high reusability with low environmental impact.

title: Starch-Hibiscus-Cellulose Nanofibrils Composite Films as a Model Antimicrobial Food Packaging Material

description: The large amounts of coffee husks (CHs) waste matter generated from coffee farms and factories has been considered as a new non-wood source of cellulose. The aim of this work was to fabricate an edible food packaging material from starch incorporating TEMPO-oxidized cellulose nano-fibrils (TOCNFs) and hibiscus extracts to boost its mechanical and antibacterial properties respectively. In this study, three schemes were employed to fabricate this enhanced novel nanocomposite film of starch, hibiscus and TOCNF Firstly, glycerol was used as the plasticizer on the formation of the starch film to give mobility to the α-D-glucose structural chains making the composite film more flexible. Secondly, TEMPO-oxidized cellulose nano-fibers derived from coffee husks were thrown into the mix to enhance the mechanical properties of the starch matrix and to control water vapor permeability and solubility. Lastly, the antimicrobial activity and UV resistance of the films were enhanced through incorporation of hibiscus crude extracts which were infused into the nanocomposite films.
