There are four main types of natural diamonds and related formation processes. The first type comprises the interstellar nanodiamond particles. The second group includes crustal nano-and micron-scale diamonds associated with coals, sediments and metamorphic rocks. The third one includes nanodiamonds and microndiamonds associated with secondary alteration and replacing of mafic and ultramafic *** fourth one includes macro-, micron-and nano-sized mantle diamonds which are associated with kimberlites, mantle peridotites and eclogites. Each diamond type has its specific characteristics. Nanosized diamond particles of lowest nanometers in size crystallize from abiotic organic matter at lower pressures and temperatures in space during the stages of protoplanetary disk formation. Nano-sized diamonds are formed from organic matter at P-T exceeding conditions of catagenesis stage of lithogenesis. Micron-sized diamonds are formed from fluids at P-T exceeding supercritical water *** diamonds are formed from metal-carbon and silicate-carbonate melts and fluids at P-T exceeding 1150℃ and 4.5 GPa. Nitrogen and hydrocarbons play an important role in diamond *** role in the formation processes increases from macro-sized to nano-sized diamond *** of nitrogen atoms into the diamond structure leads to the stabilization of micron-and nanosized diamonds in the field of graphite stability.

The work has the characters of a philosophical note, in which a new exotic version of the atom structure is discussed. According to this, the atomic nucleus consists of “normal” and “special” neutrons. Electrons are internal part of both types of neutron. Electrons can leave “normal” neutrons of the nucleus and return back with a certain probability. These processes lead to the appearance of protons in the nucleus and form the electron orbits of the atom. At the same time, it is possible that the Coulomb’s barriers of atoms and nucleus disappear at some point in time and cold nuclear reactions pass through. This assumption leads to a new exotic model of the Universe structure, namely, the existence of neutron ether, consisting of special neutrons that do not emit their own electrons. In this ethereal ocean of special neutrons, periodically provoked disturbances arise. After that, it creates pockets, clusters of our normal neutrons inherent in our world, which can already emit electrons and, consequently, create atoms. The ether gets sick from time to time. However, as a result of this disease, stars arise. Some possible stages in the creation of our world are also discussed in this paper.

Experiments on the National Ignition Facility show that multi-dimensional effects currently dominate the implosion performance. Low mode implosion symmetry and hydrodynamic instabilities seeded by capsule mounting features appear to be two key limiting factors for implosion performance. One reason these factors have a large impact on the performance of inertial confinement fusion implosions is the high convergence required to achieve high fusion *** tackle these problems, a predictable implosion platform is needed meaning experiments must trade-off high gain for performance. LANL has adopted three main approaches to develop a one-dimensional(1D) implosion platform where 1D means measured yield over the 1D clean calculation. A high adiabat, low convergence platform is being developed using beryllium capsules enabling larger case-to-capsule ratios to improve symmetry. The second approach is liquid fuel layers using wetted foam targets. With liquid fuel layers, the implosion convergence can be controlled via the initial vapor pressure set by the target fielding temperature. The last method is double shell targets. For double shells, the smaller inner shell houses the DT fuel and the convergence of this cavity is relatively small compared to hot spot ignition. However,double shell targets have a different set of trade-off versus advantages. Details for each of these approaches are described.
