Recently, precision agriculture has become a globally attractive topic. As one of the most important factors, the soil nutrients play an important role in estimating the development of precision agriculture. Detecting the content of nitrogen, phosphorus and potassium (NPK) elements more efficiently is one of the key issues. In this paper, a novel chip-level colorimeter was fabricated to detect the NPK elements for the first time. A light source?microchannel photodetector in a sandwich structure was designed to realize on-chip detection. Compared with a commercial colorimeter, all key parts are based on MEMS (Micro-Electro-Mechanical System) technology so that the volume of this on-chip colorimeter can be minimized. Besides, less error and high precision are achieved. The cost of this colorimeter is two orders of magnitude less than that of a commercial one. All these advantages enable a low-cost and high-precision sensing operation in a monitoring network. The colorimeter developed herein has bright prospects for environmental and biological applications.

Electric Literature of 125-20-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 125-20-2, Thymolphthalein, introducing its new discovery.

Acetylated corn starches with different degrees of substitution (DS 0.85, DS 1.78, DS 2.89) were synthesized by the reaction of corn starch with acetic anhydride in the presence of acetic acid under varying reaction temperatures. The product was characterized by FTIR spectroscopy, 1H NMR, X-ray diffraction and contact angle measurement. Acid-base titration and 1H NMR methods were employed to determine the degree of substitution of product. FTIR spectroscopic analysis showed that the characteristic absorption intensities of esterified starch increased with increase in the degree of substitution, and the characterized peak of hydroxyl group almost disappeared in the spectrum of DS 2.89 acetylated starch. The detailed chemical microstructure of native starch and acetylated starch was confirmed by 1H NMR, 13C NMR and 13C-1H COSY spectra. Analysis of 1H NMR spectra of acetylated starches was assigned accurately. Strong peaks in X-ray diffraction of acetylated starch revealed that new crystalline regions were formed. Compared with native starch, the hydrophobic performance of acetylated starch esters was increased. The contact angle of acetylated starch with DS 2.89 was 68.2.

SDS of cas: 4265-25-2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4265-25-2, name is 2-Methylbenzofuran. In an article，Which mentioned a new discovery about 4265-25-2

Several series of benzofurans, benzothiophenes, and benzothiazoles, all featuring the thioamide group, were synthesized and tested as novel K ATP channel openers in artificial cell systems: CHO cells transfected with SUR1/Kir6.2, and HEK 293 cells transfected with SUR2B/Kir6.1; these served as model systems for insulin-secreting pancreatic beta cells and smooth muscle cells, respectively. All compounds were investigated with respect to their binding affinity for the SUR2B-type KATP channels using [ 3H]P1075 as radioligand. Selected compounds were also tested as agonists in intact cells using DiBAC4(3) and DyeB (R7260) as membrane potential dyes. Remarkable affinity for SUR2B/Kir6.1 channels in the single-digit micromolar range was observed. In addition, benzothiazole-derived thioamides with sterically demanding, lipophilic substituents showed >100-fold selectivity in favor of SUR2B/Kir6.1. A one-carbon spacer between the heterocyclic skeleton and the thioamide moiety was observed to be crucial for affinity and selectivity. Two of the most potent and selective compounds were studied by crystal structure analyses.

In this paper, two typical Chinese lignites, Shengli lignite (SL) and Xiaolongtan lignite (XL), with different geologic ages were firstly thermal dissolved in sub- and supercritical benzene and ethanol, then soluble organic species were analyzed with Fourier transform infrared spectroscopy (FTIR), gas chromatograph/mass spectrometer (GC/MS) and atmospheric solids analysis probe/time of flight mass spectrometer (ASAP/TOF-MS). The soluble organic species yield of XL in benzene is close to that of SL in the temperature investigated, whereas the soluble organic species yield of XL in ethanol is obviously higher than that of SL at high temperature region. Obvious difference exists in the molecular composition of the soluble organic species between SL and XL. The soluble organic species of XL contain more free aliphatics but less arenes than those of SL. The arenes in the soluble organic species of XL are mainly composed of the derivatives of benzene and naphthalene, while those from SL are dominated with condensed arenes and polycyclic biphenyls. Furthermore, the free oxygen-containing organic species in SL and XL are dominated with ketones and phenols, respectively. Additionally, ASAP/TOF-MS analysis indicates that the molecular weight of soluble organic species from SL is higher than that from XL.
