Determination of the Through-Bond Carbon−Carbon and Carbon−Proton Connectivities of the Native Celluloses in the Solid State

Using the two-dimensional (2D) refocused CP-INADEQUATE spectra of natural abundance Cladophora and tunicate celluloses, we determined the 13C homonuclear through-bond correlations of cellulose Iα and Iβ, respectively. Two sets of the 13C−13C connectivities from C1 through C6 were observed in the 2D INADEQUATE spectrum of the respective cellulose where two directly bonded carbons share the common frequency in the double quantum dimension, which indicated that both cellulose Iα and Iβ contain two magnetically nonequivalent anhydroglucose residues in the unit cells. After the 13C assignment of each carbon of the cellulose Iα and Iβ, assignments of the 1H chemical shifts of protons attached to each carbon of the both allomorphs were performed by use of the 2D MAS-J-HMQC spectra of the cellulose samples for the first time. These spectra gave the through-bond 13C−1H correlations, which allowed the assignment of the 1H chemical shifts of protons that bind to C1, C3, C4, and C6 of the cellulose Iα and Iβ. From th.
Genetic variability of quantitative characters that exist in moringa (Moringa oleifera Lam.) in Tamil Nadu, India

Twenty five moringa genotypes that were collected from different geographical regions of Tamil Nadu, India were evaluated for variability, heritability and genetic advance for growth, yield and quality characters and significant variations were recorded for the investigated traits. Widest range of variation was observed in internode length and number of primary rachis. Maximum genotypic and phenotypic coefficient of variation was observed for height at first branch emergence, number of compound leaves, and number of branches at harvest, internode length and fresh leaf biomass. High magnitude of heritability coupled with high genetic advance was observed for height at first branch emergence (99.83%), number of compound leaves per tree (99.73%), number of branch at harvest (99.46%), fresh leaf biomass (99.16%), and number of leaflet per rachis (99.09%). High heritability and genetic advance indicating additive gene action suggested that simple selection could be effective for the improvement of these traits.
Simple Chemical Method for Forming Silver Surfaces with Controlled Grain Sizes for Surface Plasmon Experiments

We report on how the mirror reaction method can be used to prepare silver films with well controlled grain sizes in the range that is known to be ideal for surface plasmon experiments in the visible region of the spectrum. We characterize the morphology of the silver films by atomic force microscopy and their optical properties by UV−vis absorption spectroscopy, comparing these results with the predictions of classical electromagnetism. The colloid particle size can easily be controlled to lie in the range 50−200 nm, and their shape is approximately spherical with aspect ratios (lateral dimensions to height) in the range 1:1 to 1:2. These dimensions and morphology are ideal for surface plasmon based techniques such as surface enhanced Raman spectroscopy (SERS) and surface plasmon resonance (SPR). The method also has the added advantage that it can be used in applications where conventional coating by evaporation can damage the substrate due to heating. We give one such examplethe coating of an atomic forc.
Dielectrophoretic Behavior of Single DNA in Planar and Capillary Quadrupole Microelectrodes

Dielectrophoresis (DEP) of single DNA (about 40 kbp) labeled with a fluorophore was successfully observed in a planar quadrupole electrode cell whose working area was 65 µm in radius. The DEP behavior depended on frequency (f) of alternating current; positive DEP at lower f and negative DEP at higher f. The combination of the DEP force and a laminar flow in a capillary (82.5 µm in inner radius) with a quadrupole electrode controlled the elution of DNA from the capillary as a function of f.
Neural ODE Processes

Neural Ordinary Differential Equations (NODEs) use a neural network to model the instantaneous rate of change in the state of a system. However, despite their apparent suitability for dynamics-governed time-series, NODEs present a few disadvantages. First, they are unable to adapt to incoming data points, a fundamental requirement for real-time applications imposed by the natural direction of time. Second, time series are often composed of a sparse set of measurements that could be explained by many possible underlying dynamics. NODEs do not capture this uncertainty. In contrast, Neural Processes (NPs) are a family of models providing uncertainty estimation and fast data adaptation but lack an explicit treatment of the flow of time. To address these problems, we introduce Neural ODE Processes (NDPs), a new class of stochastic processes determined by a distribution over Neural ODEs. By maintaining an adaptive data-dependent distribution over the underlying ODE, we show that our model can successfully capture the dynamics of low-dimensional systems from just a few data points. At the same time, we demonstrate that NDPs scale up to challenging high-dimensional time-series with unknown latent dynamics such as rotating MNIST digits.
An exploratory study of electrodeposition of titanium using titanium dioxide carbon composite anode and molten aluminium cathode

The objective of this study is to deposit titanium metal on a molten metal pool of aluminium, by electrochemical reduction in titanium oxide, which is in the form of titanium dioxide carbon (TiO2–C) composite used as anodes in fused alkali chlorides. TiO2–C composite blocks were prepared by compaction. It was backed at 873–1073 K for 48 h. It is noticed that density, porosity and electrical resistivity of the blocks are increased with increase in TiO2 content. Electrochemical characteristics, namely I–V characteristics were studied using TiO2–C composite blocks as anode, molten aluminium as cathode in molten alkali chlorides. Electrolysis experiments were conducted using TiO2–C composite as anode and molten aluminium as cathode in the chloride melt at ∼1073 K. It is observed that the dissolution of anode blocks containing 70% titanium oxide were very smooth. At anode, the oxygen ion from the lattice of the TiO2 comes out and combines with carbon (anode) to form carbon monoxide and carbon dioxide. In the bath, the titanium ion forms multivalent titanium chlorides (in situ) or titanium complexes with chloride ions. At cathode, titanium chlorides/complexes, which are formed in situ, dissociate as titanium ions and reduce to titanium particles. These particles deposited on the molten aluminium cathode and sink into it. The aluminium samples sectioned from the chilled electrolytic cell were undergone for chemical analysis and microscopic investigations. The micrographs of optical and SEM revealed the presence of dendritic needles of titanium rich phase in the aluminium matrix. The EDAX analysis on the needle shaped particles showed the formation of TiAl2 phase. The Faradic current efficiency of this process was 10–30%.

Radiological Characterization of Natural Spring Waters in Eastern Black Sea Region, Turkey

The activity concentrations of 226Ra, 232Th, 40K and 137Cs radionuclides in the natural spring waters of the Eastern Black Sea region of Turkey were measured using gamma-ray spectrometry. The mean specific activities of the radionuclides in the samples were 52, 23, 379 and 24 mBq/L–1, respectively. The overall annual effective dose from all measured radionuclides was much below the World Health Organization (WHO, Geneva Switzerland) recommended reference level of 0.1 mSv.y−1 for drinking water consumption. Gross α and β activities ranged from 1 to 188 mBq/L−1 and from 3 to 91 mBq/L−1, respectively. Concentrations of elements in waters were also measured by inductively coupled plasma-optical emission spectrometry. An analysis of variance and Pearson correlation analysis were performed for radioactivity and elemental analysis. This study provides background values of investigated nucleotides in the water from the region, which could also be useful in forensic investigations to distinguish potential contributions from point pollution sources.

Influence of Chain Branching and Molecular Weight on Melt Rheology and Crystallization of Polyethylene/Carbon Nanotube Nanocomposites

In this paper, the synergistic effects that carbon nanotubes (CNTs) produce on the basic rheological properties and crystallization of polyethylenes with different branch contents and molecular weights was investigated. Multiwalled carbon nanotubes coated with polyethylene (as produced by in situ polymerization) were blended in the melt (in a 1% wt. ratio) with three polyethylene matrices of different molecular weights and branch contents. Transmission electron micrographs demonstrated excellent carbon nanotube dispersion in all samples and the existence of a geometrical percolation network. The rheological and calorimetric properties of the nanocomposites were determined and the results compared to those obtained for neat polyethylene resins. Both Newtonian viscosity and steady-state shear recoverable compliance increased with the addition of CNTs in all cases. However, the increase was strongly dependent on the molecular weight (and dispersity index) of the matrices regardless of the branch content. A n.
Use of Micellar-Enhanced Ultrafiltration to Remove Dissolved Organics from Aqueous Streams

Abstract Traditional ultrafiltration is ineffective at removing dissolved low molecular weight organics from water. In micellar-enhanced ultrafiltration (MEUF), surfactant is added to the water at concentrations well above the critical micelle concentration. Almost all of the organic originally dissolved (the solute) solubilizes in the micelles formed by the surfactant. The solution then passes through an ultrafiltration membrane with pores small enough to block micelle passage. The permeate contains (at most) only the unsolubilized solute and the surfactant monomer, both at very low concentrations. In this work, the criteria for selecting a surfactant are considered and MEUF is tested on an aqueous stream containing 4-tert-butyl-phenol with hexadecylpyridinium chloride as the surfactant. At high surfactant concentrations (0.25 M) in the retentate, rejections decrease, probably owing to the formation of n-mers (e.g., dimers, trimers, etc.) which are able to pass through the pores along with some solubiliz.
Theoretical calculation of bond dissociation energies and heats of formation for nitromethane and polynitromethanes with density functional theory

The CNO2 bond dissociation energies (BDEs) and the heats of formation (HOFs) of nitromethane and polynitromethanes (dinitromethane, trinitromethane, and tetranitromethane) system in gas phase at 298.15 K were calculated theoretically. Density functional theory (DFT) B3LYP, B3P86, B3PW91, and PBE0 methods in combination with different basis sets were employed. It was found that the CNO2 bond BDEs can be improved from B3LYP to B3PW91 to B3P86 or PBE0 functional. Levels of theory employing B3P86 and PBE0 functionals were found to be sufficiently reliable without the presence of diffusion functions. As the number of NO2 groups on the same C atom increases, the PBE0 functional performs better than the B3P86 functional. Regarding the calculated HOFs, all four functionals can yield satisfactory results with deviations of <2 kcal mol−1 from experimental ones for CH2(NO2)2 and CH(NO2)3, when the diffusion functions are not augmented. For the C(NO2)4 molecule, the large basis sets augmented with polarization functions and diffusion functions are required to yield a good result. © 2006 Wiley Periodicals, Inc.

Effect of the Temperature on the Composition of Lignin Pyrolysis Products

The temperature dependence of the pyrolysis products of two types of lignin (Alcell lignin and Asian lignin) was investigated using pyrolysis−gas chromatography−mass spectrometry (PyGC−MS). About 50 compounds were identified and quantified for each type of lignin over a temperature range of 400−800 °C. The maximum yield of phenolic compounds was obtained at 600 °C for both lignins, which was 17.2% for Alcell lignin and 15.5% for Asian lignin. Most of the phenolic compounds had an individual yield of less than 1%; however, for Alcell lignin, 5-hydroxyvanillin was the highest yield at 4.29 wt % on dry ash-free lignin, and for Asian lignin, 2-methoxy-4-vinylphenol was the highest yield at 4.15 wt % on dry ash-free lignin.
Electronic states of Ar2F and Kr2F

Ab initio POL CI calculations have been performed on the low‐lying states of Ar2F and Kr2F. The results support a simple diatomics‐in‐molecules description of Rg2F (Rg=rare gas). In each case only one ionic state (2 2B2) is found to be stable (by 0.6 eV) relative to Rg+F−+Rg. The equilibrium geometry is found to be an isosceles triangle where the Rg–Rg distance is 0.02 A shorter than that in the 2Σ+u state of Rg+2 and the Rg–F distance is 0.14 A greater than that in the 2 2Σ+ state of RgF. There are two dipole‐allowed emissions (2 2B2→1 2A1, 2 2B2→1 2B2) of comparable strength and wavelength (267 and 274 nm, respectively, in Ar2F and 357 and 368 nm, respectively, in Kr2F). The calculated wavelengths are in good agreement with the broad bands at 290 and 400 nm observed in e‐beam pumped Ar or Kr/F2 mixtures, confirming the earlier assignment of these bands to Ar2F and Kr2F, respectively. The radiative lifetime of the 2 2B2 is calculated to be 132 ns for both Ar2F and Kr2F. There are four dipole‐allowed abso.

UV and solar light degradation of dyes over mesoporous crystalline titanium dioxides prepared by using commercial synthetic dyes as templates

Although photosensitization of titania by organic dyes is one of the conventional ways for visible-light utilization of titania, previous studies have not yet addressed the use of dyes as templates in the synthesis of mesoporous materials, let alone the simultaneous achievement of highly crystalline mesoscopic ordering and visible-light photocatalytic activity. In this work, fourteen commercial synthetic dyes were directly used as structure-directing agents which convert to carbonaceous materials after 400 °C calcination in synthesis of thermally stable mesostructured titania. This in situ carbon enhanced the visible light photocatalytic activities for the degradation of aqueous dyes. The synthesized mesoporous titania samples were characterized by a combination of various physicochemical techniques, such as XRD, SEM, HRTEM, nitrogen adsorption/desorption, TGA–DSC, XPS, diffuse reflectance UV–vis and FT–IR. Most of prepared mesoporous titania photocatalysts exhibited better activity under outside solar light than under artificial UV light, due to the presence of carbonaceous species which were transferred from the dye templates. The reported strategies combine sol-gel chemistry and self-assembly routes directly using dye templates that tune the material's architecture, texture and particularly function, visible-light photocatalysis.

Qualitative and Textural Changes in Fresh Okra Pods (Hibiscus esculentus L.) under Modified Atmosphere Packaging in Perforated Film Packages

Improper post-harvest handling and storage under room temperature lead to high loss of moisture resulting in loss of strength and development of flaccidity in okra tissues, apart from the loss of its characteristic green color. In this study, different weights of freshly harvested okra pods (Hibiscus esculentus L.) were stored at 15°C and 75% relative humidity packaged under modified atmosphere (MAP) in 35 μm thick polypropylene film packages to assess the effect of different in-pack gaseous compositions of O2 and CO2 on the properties of okra. During storage, the normal freshness indicators of okra namely, the bright green color and ease of snapping at the tip served as the prominent qualitative and textural parameters, indicative of the acceptability of okra. Results indicated that an in-pack gaseous range for O2 (6.3-8.4%) and CO2 (10.7-11.8%) under MAP resulted in maintenance of green color and β-carotene in the pericarp, and ascorbic acid in the seeds as well as other qualitative parameters. Further, the texture analysis of okra at the pre-determined snapping point at the tip and also along the longitudinal portion showed that MAP stored okra were snapping easily at the tips and had a very slight increase in the other mechanical properties which were considered to be within acceptable limits.
