Irradiating the Path to High-Efficiency Zn-Ion Batteries: An Electrochemical Analysis of Laser-Modified Anodes.

Global energy consumption is increasing yearly, yet the world is trying to move toward carbon neutrality to mitigate global warming. More research is being done on energy storage devices to advance these efforts. One well-known and widely studied technology is Zn-ion batteries (ZIBs).

[Hybridization of crucian carp, Carassius carassius (Linnaeus, 1758), in Ukrainian reservoirs and genetic structure of hybrids].

Hybridization of crucian carps Carassius carassius in polyspecific crucian populations of reservoirs of Ukraine and genetic structure of the hybrids were investigated using biochemical gene marking and cytometric procedure. The fact of wide hybridization between C. auratus and C.

[Genetic differentiation and alozyme variation of shads of genus Alosa (Clupeiformes, Alosiinae) from the Azov-Black Sea Basin].

Biochemical variation and differentiation of three species of Black-Azov sea shads (Alosa immaculata, A. caspia, A. maeotica) from three local stocks of Danube, Dnepr and Azov sea has been estimated.

Silica gel modified with lumogallion for aluminum determination by spectroscopic methods.

Simple, easy to use and selective method of Al(III) sorption-spectroscopic (SS) determination was proposed. For this purpose, silica modified with tridecyloctadecylammonium chloride(SGII) using adsorption technique and glass slide modified with thin silica-poly(dimethyldiallyl-ammonium chloride) (SGI) composite film obtained by sol-gel technique were worked out. It was shown that lumogallion (LG) easily absorbs on SGI and SGII.

[Genetic structure of the spawning population of Danube shad, Alosa pontica, Eichwaldt 1838 (Clupeiformes, Alosiinae)].

The genetic structure of the population of Danube shad, Alosa pontica, has been studied by means of analysis of 3 polymorphic biochemical gene loci. The results of the study provide evidence of its genetic heterogeneity which is expressed by: firstly, an unbalanced ratio of genotype loci manifested by an excess of rare homozygotes and deficite of the correspoding heterozygotes, and secondly, differences in the allele frequencies between shad populations arriving for spawning in March-April and May-June. It is suggested that there could be two causes of heterogeneity: one due to the introgressive hybridization between various forms of A.
