Nitrogen-doped carbon dots with excellent water- and ethanol-solubility were facilely prepared from plant cytoplasm via a one-step hydrothermal route and revealed as low-cost, label-free and highly sensitive and selective probes for detecting p-nitroaniline in both aqueous and soils owing to a proposed hydrogen-bonding effect.

Abstract The distribution of nitrogen between the different terrestrial reservoirs (core-mantle-atmosphere) and how this may have changed since earliest planetary stages is uncertain. In particular, primordial degassing processes magma ocean its role in formation atmosphere remains to be quantified. Since no geological samples can capture early process, we need go through thermodynamic modeling...

[structure: see text] (2R,3R)-Aminoproline, a pyrrolidine-based beta-amino acid, was synthesized and incorporated into hexa-beta-peptide 4. This residue confers water solubility when the ring nitrogen is protonated and allows for 12-helix formation in aqueous solution. Circular dichroism spectra display the 12-helical signature, and 12-helical structure was confirmed by 2D NMR analysis.

Grafting polymers to nanoparticles is one approach used to control and enhance the structure and properties of nanomaterials. However, predicting the aggregation behavior of tethered nanoparticles (TNPs) is a somewhat trial and error process as a result of the large number of possible polymer tethers, nanoparticles, and solvent species that can be studied. With the main goal of understanding ho...

In this study, the ion association phenomenon in the saturated solution of KCl in the mixed solvent(methanol+water) was studied. The solubility of this compound in the mixed solvent (methanol+water by value percent of methanol = 60%), and in the presence of various molarities of NaNO3 wasdetermined by the solvent evaporation method at 25.0°C. The results enable us to estimate the valueof thermo...

Soluble spray dried protein powder (CRP) was made from catfish roe and its physical and nutritional properties were evaluated. An emulsion system (CRPE) was developed using CRP and rheological properties compared with two commercial mayonnaises (RME and RVE). CRP contained 67% protein, 4.5% moisture, 10% ash, and 18.3% fat. CRP had a high content of essential amino acids and desirable mineral c...

Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...

Previously authors have reported facts that nitrogen (N2) and oxygen solubilities in styrene is the same as those benzene divinylbenzene at 303 K. Though three compounds an atomic composition, (CH)n (n=6, 8 10), gas are thought to depend on number of aromatic carbons solution. Then, named it ‘a key group solubility’. In this research, was investigated for N2 solubility methyl methacrylate (MMA)...
