Study of Thermal Insulation Performance of Layered Jute Nonwoven: A Sustainable Material

An eco-friendly sustainable thermal insulator has been developed as a replacement of some commercially available manmade materials to control heat transfer in case of buildings, and semi-permanent/temporary structures. Jute felts were prepared by needle pinching of fiber fleece. It is a self-sustained semi-rigid structure and could be placed on various surface profiles of the building/structure due to its balanced flexural rigidity and surface property of fiber. Effect of areal density, thickness, and number of layers of jute felt on its major thermal insulation property parameters were studied. Some major structural parameters of felts viz., pore size, bulk density, and air fraction as gas pockets in fibrous structure were analyzed and correlated with the insulation property. Felt having 500 g/m(2) areal density showed best specific thermal insulation performance. When it was used in four layers, its thermal insulation value reached up to 341 m(2)K/kW, which is much comparable to those of glass wool (320 m(2)K/kW), nitrile rubber (320 m(2)K/kW), and polystyrene (381 m(2)K/kW) insulators. The cost of jute felts ($ 2.81 for four layers of 500 g/m(2)) was much comparable to synthetics ($2.9 for glass wool and $ 2.7 for nitrile rubber) of similar thermal insulation value. It also facilitates remarkable saving of costly floor space to the extent of 28% as compared to synthetics. The ease of tailorability of jute felt was also studied by measuring drapability, tensile strength, tear strength, and energy required to cut the felt. Inherent multiple lumens within fiber structure, partial anisotropy of polymer chains, and innumerable tiny gas pockets within the felt structure are the major reasons for the high thermal insulation of jute felt.

8-cyanobenzothiazinone analogs with potent antitubercular activity

8-Nitrobenzothiazinones (BTZs) exemplified by macozinone are a new class of antitubercular agents with exceptionally potent activity. The aryl nitro group has been considered indispensable for activity since this is bioactivated within mycobacteria by the flavoenzyme DprE1 to a reactive nitroso metabolite that covalently labels Cys387. However, the aryl nitro group is a potential liability with regards to safety, stability, and resistance. In this paper, we introduced a nitrile as a bioisosteric replacement of the nitro group, which we hypothesize can maintain a similar covalent mechanism of inhibition, but mitigate against the aforementioned concerns. 8-cyanobenzothiazinone 1d displayed potent antitubercular activity with an MIC of 130 nM and had an improved volume of distribution in mice that increased the intrinsic half-life by twofold compared to macozinone. Analysis of the C-2 substituent of 1d revealed similar structure-activity relationships as observed for macozinone. Overall, the results confirm the 8-nitro group of benzothiazinones can be successfully replaced with a nitrile to retain useful activity and favorable pharmacokinetic properties. [GRAPHICS] .

Tribological behaviors of the water-lubricated rubber bearings under different lubricated conditions

Purpose – This study aims to evaluate the tribological behavior of water-lubricated rubber bearings sliding against stainless steel under different lubricate conditions. Design/methodology/approach – The water-lubricated rubber bearings under various normal loads and sliding speeds were carried out on the ring-block friction test, and the wear morphology is test conducted by using scanning electron microscope. Findings – The results indicate that the surface of water-lubricated rubber bearings has a more alternative friction coefficient and wear rate under seawater than other lubricate conditions. The seawater not only acts as a lubricating medium but also brings microstructure while corroding the rubber interface, thereby further enhancing the lubricating effect and storing abrasive debris. Originality/value – In this paper, tribological properties of the water-lubricated rubber bearing on ring-block friction test has been investigated. Water-lubricated rubber bearing was carried out on various lubricate conditions, and the friction coefficient, wear rate and worn surface were analyzed. Also, the effects of sliding speeds were investigated. Peer review – The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-06-2020-0204/

Low-temperature catalytic conversion of alkaline sewage sludge bio-oil to biodiesel: Product characteristics and reaction mechanisms

Sewage sludge is a promising biomass alternative for the production of liquid biofuels. In this study, bio-oil derived from the fast pyrolysis of domestic sewage sludge was upgraded in a micro Robinson-Mahoney reactor at 4 MPa and 260 degrees C, and in the presence of hybridized Ni/HZSM-5 catalyst and ethanol. Fourier transform infrared and gas chromatography-mass spectrometry analyses were used to identify the functional groups and chemical components of raw and upgraded sewage sludge bio-oil. Results showed that catalytic upgrading reduced the relative content of acids, aldehydes, phenols, ketones, and nitrogenated compounds in the pyrolytic bio-oil. Thus, the main components of the upgraded bio-oil product included esters (48.59%), alkanes (10.12%), aromatics (9.38%), and alkenes (5.08%). Water and nitriles in the raw pyrolytic bio-oil together with in-situ-produced carbon oxides helped in the esterification of raw bio-oil. Reaction mechanisms such as nitrile hydrolysis, hydrogenation, and esterification were proposed to elucidate the conversion of the non-acidic pyrolytic bio-oil into ester-dominating upgraded bio-oil. Overall, upgrading sewage sludge pyrolytic oil is crucial to produce high-quality diesel-range biofuel. (C) 2020 Elsevier B.V. All rights reserved.

On the intrinsic reactivity of highly potent trypanocidal cruzain inhibitors

The cysteine protease cruzipain is considered to be a validated target for therapeutic intervention in the treatment of Chagas disease. Hence, peptidomimetic cruzipain inhibitors having a reactive group (known as warhead) are subject to continuous studies to discover novel antichagasic compounds. Here, we evaluated how different warheads for a set of structurally similar related compounds could inhibit the activity of cruzipain and, ultimately, their trypanocidal effect. We first investigated in silico the intrinsic reactivity of these compounds by applying the Fukui index to correlate it with the enzymatic affinity. Then, we evaluated their potency against T. cruzi (Y and Tulahuen strains), which revealed the reversible cruzain inhibitor Neq0656 as a better trypanocidal agent (ECY50Y.strain = 0.1 mu M; SI = 58.4) than the current drug benznidazole (EC50Y.strain = 5.1 mu M; SI > 19.6). We also measured the half-life time by HPLC analysis of three lead compounds in the presence of glutathione and cysteine to experimentally assess their intrinsic reactivity. Results clearly illustrated the reactivity trend for the warheads (azanitrile > aldehyde > nitrile), where the aldehyde displayed an intermediate intrinsic reactivity. Therefore, the aldehyde bearing peptidomimetic compounds should be subject for in-depth evaluation in the drug discovery process.

Modeling transmission windows in Titan’s lower troposphere: Implications for infrared spectrometers aboard future aerial and surface missions

From orbit, the visibility of Titan’s surface is limited to a handful of narrow spectral windows in the near-infrared (near-IR), primarily from the absorption of methane gas. This has limited the ability to identify specific compounds on the surface-to date Titan’s bulk surface composition remains unknown. Further, understanding of the surface composition would provide insight into geologic processes, photochemical production and evolution, and the biological potential of Titan’s surface. One approach to obtain wider spectral coverage with which to study Titan’s surface is by decreasing the integrated column of absorbers (primarily methane) and scatterers between the observer and the surface. This is only possible if future missions operate at lower altitudes in Titan’s atmosphere. Herein, we use a radiative transfer model to measure in detail the absorption through Titan’s atmosphere from different mission altitudes, and consider the impacts this would have for interpreting reflectance measurements of Titan’s surface. Over our modeled spectral range of 0.4-10 mu m, we find that increases in the width of the transmission windows as large as 317% can be obtained for missions performing remote observations at the surface. However, any appreciable widening of the windows requires onboard illumination. Further, we make note of possible surface compounds that are not currently observable from orbit, but could be identified using the wider windows at low altitudes. These range from simple nitriles such as cyanoacetylene, to building blocks of amino acids such as urea. Finally, we discuss the implications that the identifications of these compounds would have for Titan science.

Conversions of aryl carboxylic acids into aryl nitriles using multiple types of Cu-mediated decarboxylative cyanation under aerobic conditions

Here, we used malononitrile or AMBN as a cyanating agent to develop efficient and practical protocols for Cu-mediated decarboxylative cyanations, under aerobic conditions, of aryl carboxylic acids bearing nitro and methoxyl substituents at the ortho position as well as of heteroaromatic carboxylic acids. These protocols involved economical methods to synthesize value-added aryl nitriles from simple and inexpensive raw materials. Further diversification of the 2-nitrobenzonitrile product was performed to highlight the practicality of the protocols.

Understanding the Mechanism between Antisolvent Dripping and Additive Doping Strategies on the Passivation Effects in Perovskite Solar Cells

Perovskite polycrystalline films contain numerous intrinsic and interfacial defects ascribed to the solution preparation process, which are harmful to both the photovoltaic performance and the stability of perovskite solar cells (PVSCs). Although various passivators have been proved to be promising materials for passivating perovskite films, there is still a lack of deeper understanding of the effectiveness of the different passivation methods. Here, the mechanism between antisolvent dripping and additive doping strategies on the passivation effects in PVSCs is systematically investigated with a nonfullerene small molecule (F8IC). Such a passivated effect of F8IC is realized via coordination interactions between the carbonyl (C=O) and nitrile (C-N) groups of F8IC with Pb2+ ion of MAPbI(3). Interestingly, F8IC antisolvent dripping can effectively passivate the surface defects and thus inhibit the nonradiative charge recombination on the upper part of the perovskite layer, whereas F8IC additive doping significantly reduces the surface and bulk defects and produces a compact perovskite film with denser crystal grains, thus facilitating charge transmission and extraction. Therefore, these benefits are translated into significant improvements in the short-circuit current density (J(sc)) to 21.86 mA cm(-2) and a champion power conversion efficiency of 18.40%. The selection of an optimal passivation strategy should also be considered according to the energy level matching between the passivators and the perovskite. The large energetic disparity is unsuitable for additive doping, whereas it is expected in antisolvent dripping.

Potassium tert-Butoxide Promoted Synthesis of 4,5-Diaryl-2H-1,2,3-triazoles from Tosylhydrazones and Nitriles

Intermolecular cycloaddition of tosylhydrazones with nitriles was investigated.t-BuOK was shown to be an excellent base for increasing the effectiveness of the reaction in this protocol, and homocoupling of the tosylhydrazones was significantly inhibited by using xylene as a solvent. Through this transformation, a variety of 4,5-diaryl-2H-1,2,3-triazoles were prepared in good to excellent yields and with high purities. The process is azide-free and transition-metal-free.

Comparative study of fluxional processes at two different classes of eight-coordinate rhenium(V) polyhydride complexes

Two different structural types of dodecahedral rhenium(V) tetrahydride complexes were identified as capable of providing insight into a pseudorotational exchange of ligands at such complexes. One type of complex afforded an inequivalent set of NMR-active phosphorus atoms that occupy B sites in the rhenium coordination sphere along with four hydride ligands in the dodecahedral A sites. A second type of complex afforded the potential to inhibit the pseudorotational exchange of ligands at such complexes due to the presence of a chelating bidentate ligand. A pair of each type of complexes were studied by variable temperature NMR measurements and simulation of those measurements. The first type of complex exhibited pseudorotation of both the A site hydride ligands and the B site triphenylphosphine ligands. The first type of complexes also exhibited a pairwise exchange of the two inequivalent hydride ligands on the complexes. The second type of complex did not exhibit pseudorotational exchange of the A site hydride ligands, presumably due to the chelating bidentate ligand bound to rhenium. Instead, the A site hydride ligands of the second type of complex exhibited only exchange with the single B site hydride ligand through either a pairwise or a turnstile type of mechanism. Neither type of complex exhibited any direct intermolecular exchange of protons from the hydride ligand set with adventitious water from the solvent matrix. The value of Delta G(240)(double dagger) for each of the identified fluxional processes was close to 12 kcal/mol. The values of Delta S-double dagger for each fluxional process suggest that none of the processes are dissociative in nature.
