Abstract Research into new composites utilizing cubic boron nitride (PcBN) shows promise for enhancing cutting tool performance. The unique properties of these materials stem from the addition of microfibers made of refractory compounds to their stru

Pure titanium composed of α single-phase has important applications for its excellent mechanical, physical, and chemical properties, which also impose high requirements on its surface finish. However, pure titanium is a difficult-to-machine material

The reaction mechanism of the formation of hybrid oligomers based on complexes compounds of metal and oligophenylene is considered. The structure of compounds formed in such a reaction is determined. The effect of the addition of dimethyl sulfoxide o

The number density of small dark matter (DM) halos hosting faint high-redshift galaxies is sensitive to the DM free-streaming properties. However, constraining these DM properties is complicated by degeneracies with the uncertain baryonic physics gov

The synthesis of nanodispersed partially oxidized metal particles by the reduction of salts of the corresponding elements in diethylene glycol is studied. The possibility of functionalization of the surface of the forming particles during in-situ gra

Some of recent detections of a narrow emission line at ∼3.5 keV have been accompanied by subsequent non-detections in the same sources, raising discussion about the actual level of systematic errors. In this paper, we study the systematics caused b

In this paper, we formulate a new model of density distribution for halos made of warm dark matter (WDM) particles. The model is described by a single microphysics parameter - the mass (or, equivalently, the maximal value of the initial phase-space d

Dwarf spheroidal galaxies (dSphs) are the most compact dark matter-dominated objects observed so far. The Pauli exclusion principle limits the number of fermionic dark matter particles that can compose a dSph halo. This results in a well-known lower

The recent detection of the 21-cm absorption signal by the EDGES collaboration has been widely used to constrain the basic properties of dark matter particles. However, extracting the parameters of the 21-cm absorption signal relies on a chosen param
