Bankruptcy is the legitimate procedure by which monetarily troubled firms, people, and sporadically governments settle their obligations. The insolvency procedure for firms assumes a focal job in financial aspects, since rivalry drives the most wasteful firms bankrupt, subsequently raising the normal proficiency level of those remaining. This study provides a comparative analysis of the most significant aspects of bankruptcy for individuals in Russia and the United States. The objective of the study was to determine the conditions involved in declaring a citizen insolvent in US and Russian law, for which we studied the ways of filing applications in these countries, as well as some methods of abuse by creditors that reduce the effectiveness of the bankruptcy institu-tion, and the ways to minimize them. Based on the results of the analysis, proposals were made to improve the legislation that governs people's bankruptcy. These proposals are based on the positive experience of the United States in the field of legal regulation of insolvency institutions.

Hydrogen is the key element to accomplish a carbon-free based economy. Here, the first evidence of plasmonic gallium (Ga) nanoantennas is provided as nanoreactors supported on sapphire (α-Al2O3) acting as direct plasmon-enhanced photocatalyst for hydrogen sensing, storage, and spillover. The role of plasmon-catalyzed electron transfer between hydrogen and plasmonic Ga nanoparticle in the activation of those processes is highlighted, as opposed to conventional refractive index-change-based sensing. This study reveals that, while temperature selectively operates those various processes, longitudinal (LO-LSPR) and transverse (TO-LSPR) localized surface plasmon resonances of supported Ga nanoparticles open selectivity of localized reaction pathways at specific sites corresponding to the electromagnetic hot-spots. Specifically, the TO-LSPR couples light into the surface dissociative adsorption of hydrogen and formation of hydrides, whereas the LO-LSPR activates heterogeneous reactions at the interface with the support, that is, hydrogen spillover into α-Al2O3 and reverse-oxygen spillover from α-Al2O3. This Ga-based plasmon-catalytic platform expands the application of supported plasmon-catalysis to hydrogen technologies, including reversible fast hydrogen sensing in a timescale of a few seconds with a limit of detection as low as 5 ppm and in a broad temperature range from room-temperature up to 600 °C while remaining stable and reusable over an extended period of time. ; The authors thank all of the students and colleagues in their groups who were actively involved with nanoparticles research.
