This effect has been variously described as a depression of the equilibrium melting point, a purely probabilistic effect, a result of complex hydrogen or polar interactions, and so on, and has been reported nigh exclusively in systems with geometric constraints on the order of single nanometers12...
The system is capable of bringing both ambient air into the optical cell as well as air from an in-flight gas addition system used forin situcalibration. The ICOS instrument is equipped with a gas deck that consists of two high pressure gas bottles capable of delivering dry air or air with...
Water is a polar solvent and there is hydrogen bonding between water molecules. So ionic substances and polar molecules can dissolve in it. Water can also carry non soluble substance like starch. So it is a suitable transporting medium in livingorganisms. 近几年,水的作用考察得很少,但是这个考点...
Frozen water has a quasi-liquid layer at its surface that exists even well below the bulk melting temperature; the formation of this layer is termed premelting. The nature of the premelted surface layer, its structure, thickness and how the layer changes with temperature have been debated for ...
This approach is based on generalized additive models (GAMs; Wood, 2011, Wood et al., 2016) that are an effective approach for estimation of non-linear seasonal or interannual trends in environmental time series (Augustin et al., 2013, Ferguson et al., 2008, Orr et al., 2015, Pedersen ...
The manipulation of nanoparticles in water is of essential importance in chemical physics, nanotechnology, medical technology, and biotechnology applications. Generally, a particle with net charges or charge polarity can be driven by an electric field. However, many practical particles only have weak ...
Biochar generated at lower temperatures is deemed to be more suitable for removing polar organic and inorganic pollutants through oxygen-containing functional groups, precipitation and electrostatic attraction. This review also presents the existing obstacles and future research direction related to biochar-...
Role of hydroxylation for the atomic structure of a non-polar vicinal zinc oxide Article Open access 20 January 2021 Introduction Generating hydrogen from water is one of the attractive research fields motivated by the quest for sources of clean energy in modern society1,2. Numerous strategies ha...
Our results show that groundwater discharge to Arctic lakes is a pervasive external source of CH4, with the potential to sustain total lake CH4emissions. However, other lake processes that can substantially control lake CH4emissions need to be considered. For instance, large amounts of CH4are pro...
Fully water-dilutable microemulsions are disclosed comprising comprising (A) an active ingredient which has a solubility in water of less than 1% at room temperature and a melting point of less than 100 DEG C; (B) a non-polar, water immiscible solvent capable of dissolving at least 5% by ...
