There is limited knowledge about how the interaction of dissolved organic carbon (DOC) and inorganic nitrogen (N) released into the soil just after freezing can affect methane (CH4) uptake in forest soils. Here, we present how freezing treatment and glucose, as a DOC source, can affect the roles of NH4(+)-N and NO3(-)-N in inhibiting soil CH4 uptake, by using soil-core incubation experiments. A...

In this study, nanocomposite of ternary nitrate molten salt induced with MXene is developed. LiNO3-NaNO3-KNO3 wt% 35:12:53 and 35:10:55 are produced doped in the 0.2, 0.5, 1.0, 1.5. FTIR result indicates composites had no chemical reaction occurred during preparation. UV-VIS analysis shows absorption enhancement respect to concentration MXene. Thermogravimetric (TGA) was used measure thermal st...

Ammonia is an important component of the nitrogen cycle and because it is oxidized in the environment by microorganisms (i.e., nitrification), it is a large source of available nitrogen in the environment (Raven & Johnson 1989). The complexity of the nitrogen cycle, various rate determining environmental conditions for nitrification (e.g., pH, temperature), and the physical behaviour of ammonia...

In another paper [1914] an account will be found of a new method for the estimation of aspartic and glutaminic acids in the hydrolytic products of proteins, depending upon the insolubility of their calcium salts in alcohol. In studying the influence of lime upon glutaminic acid in aqueous solution at higher temperatures it was found that the amino-nitrogen content had been considerably reduced....

Ionic liquid azides from azidoethyl, alkyl, and alkenyl substituted derivatives of 1,2,4- and 1,2,3-amino-triazoles were prepared and examined for the first time to investigate their structural and physical properties. All reported salts possess melting points below 100 degrees C. The unique character of these newly discovered ionic liquid azides is based upon the fact that these molecules are ...

We determined: (a) the physiological consequences of overproduction of putrescine in transgenic poplar (Populus nigra x maximoviczii) cells expressing an ornithine decarboxylase transgene; and (b) effects of variation in nitrogen (N) concentration of the medium on cellular polyamine concentration in transgenic and non-transgenic cells. Cells grown in the presence of supplemental (to the normal ...

ABSTRACT Saturated salt solutions produce environments with specific relative humidities used in several applications, such as determining water sorption isotherms of foods. However, the preparation saturated requires knowledge solubility data. Thus, objective this work was to determine 14 salts: lithium bromide (LiBr), chloride (LiCl), iodide (LiI), magnesium (MgCl2), sodium (NaI), potassium c...

Thallium (Tl) is a highly toxic heavy metal that poses threat to various organisms, including human beings. In plants, Tl mostly present as the uncomplexed Tl+ species, and its uptake by plants follows similar trend of other monovalent ions such NH4+, Cs+, K+, Rb+, others. this study, we investigated relationships between concentrations in barley sunflower extractable-Tl acidic, neutral, alkali...

A new method for the extraction of the active coagulation component from Moringa oleifera seeds was developed and compared with the ordinary water extraction method (MOC-DW). In the new method, 1.0 mol l-1 solution of sodium chloride (MOC-SC) and other salts were used for extraction of the active coagulation component. Batch coagulation experiments were conducted using 500 ml of low turbid wate...
