A robust 3-D porous structure of formula [Ln2(PDC)3(DMF)2]∞ has been constructed from lanthanide cations (Ln = Er3+ or Y3+) and the non-linear anionic bridging ligand, pyridine-3,5-dicarboxylate (PDC2-) in dimethylformamide (DMF). The solvated framework polymers {[M2(PDC)3(DMF)2]·n(solv)}∞ (M Er, Y) undergo a solid-state, crystal-to-crystal reaction upon heating are converted via loss both sorbed coordinated solvent rearrangement core to give desolvated form with retention structural...
The number of dairy cows in Idaho has increased by approximately 80% the last decade, with majority these facilities located southern Idaho, causing air quality concerns this region. To determine potential impacts facilities, we measured ammonia (NH3), methane (CH4), and nitrous oxide (N2O) concentrations over pens, wastewater storage pond, composting area on a 700-cow open-lot using open-path Fourier transform infrared spectrometry (OP/FTIR). Concentrations were for one or two days at each...
The Rhizotrons method is an important means of detecting dynamic growth and development phenotypes plant roots. However, the segmentation root images a critical obstacle restricting further this method. At present, researchers mostly use direct manual drawings or software-assisted to segment systems for analysis. Root can be segmented from obtained by method, then, system lengths diameters with software. This type image extremely inefficient very prone human error. Here, we investigate...
Abstract In this study, the mechanical performance of polyurethane (PU)‐modified asphalt was investigated. To end, molecular dynamics method adopted to study influence PU modifier on compatibility, properties, and structure asphalt. Using Materials Studio software, a four‐component model asphalt, model, an asphalt–PU mixed system were constructed, density glass transition temperature () used verify aforementioned models. Molecular simulations three models conducted under different...
A technique for spectral searching with noisy data is described that improves the performance over contemporary approaches. Instead of simply calculating correlation coefficient between spectrum an unknown and a series reference spectra, greater weight given to more intense features in spectra. The array, w, by |r|/{1 + d}, where vector r represents difference vector, d, contains sample points, equal |s-kr|, k scaling factor eliminates effect signal strength. By this approach, large only...
Peanut pod rot is one of the major plant diseases affecting peanut production and quality over China, which causes large productivity losses challenging to control. To improve disease resistance peanuts, breeding significant strategy. Crucial preventative management measures include grading screening high-contributed genes that are highly resistant should be carried out. A machine vision-based approach for individual cases was proposed in this study, avoids time-consuming, labor-intensive,...
The study of the reactions transition metal atoms with water is continued in this work. Here we report Fe H2O and FeO H2. In agreement previous thermal atom experiments, laser-ablated reacted to form FeOH2 HFeOH molecules as characterized by matrix isolation FTIR spectroscopy. On photolysis, could further insert into OH bonds a stepwise pattern multi metal−oxo core species including HFeOFeH, HFeOFeOH, possibly HFeOFeOFeH, which were identified isotopic substitutions density functional...
A technique for automatically correcting the baseline of open-path Fourier transform infrared spectra is described in which are decomposed into high-frequency (details) and low-frequency (discrete approxima tions) information using a wavelet transform. After an appropriate number iterations, n, discrete approximation simulates spectrum. By setting nth to zero reversing this process, reconstructed signal contains only components original on that approximately flat at absorbance. When small...
A recently developed chemical shift anisotropy amplification solid-state nuclear magnetic resonance (NMR) experiment is applied to the measurement of tensors in three disaccharides: sucrose, maltose, and trehalose. The measured tensor principal values are compared with those calculated from first principles using density functional theory within planewave−pseudopotential approach. In addition, a method assigning poorly dispersed NMR spectra, based on comparing experimental anisotropies as...
The reactions of Mn atoms with water and MnO H2 have been studied using matrix-isolation FTIR DFT theoretical calculations. In solid argon, atom reacted H2O molecule to form the MnOH2 complex spontaneously. Photolysis destroyed produced inserted HMnOH molecule. addition, HMnOMnH, Mn(OH)2, HMnOMnOH, posssibly HMnOMnOMnH molecules were also on photolysis. Reaction gave (H2)MnO without activation energy. as well. aforementioned species identified via isotopic substitutions well density...
The effect of a nonlinear response mercury cadmium telluride (MCT) detectors to photon flux is cause large offset and slow variation in the zero-line single-beam Fourier transform infrared (FT-IR) spectra, which dramatically reduce accuracy strongly absorbing bands or lines can be measured. We describe noniterative numerical technique by baseline corrected adjusting values maximum point interferogram (the "centerburst") points on either side. relies presence three spectral regions at signal...
