CuAl8 alloy finds applications in industrial components, where a good anti-corrosion and anti-wearing propertiesare required. The alloy has a medium strength and a good toughness with an elongation to fracture at roomtemperature of about 40%. [...]

Na superionic conductor structured Na3V2(PO4)3 cathodes have attracted great interest due to their long cycling lifespan and high thermal stability rendered by the robust 3D framework. However, their practical application is still hindered by the high cost of raw materials and limited energy density. [...]

We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle ϕ$_{3}$ (also known as γ) using a model-independent Dalitz plot analysis of B$^{+}$ → D ($ {K}_S^0 $h$^{+}$h$^{−}$)h$^{+}$, where D is either a D$^{0}$ or $ \overline{D} ^{0}$ meson and h is either a π or K. This is the first measurement that simultaneously uses Belle and Belle II data, combining samples corresponding to integrated luminosities of 711 fb$^{−1}$ and 128 fb$^{−1}$, respectively [...]

The studies of structural, optical and luminescent properties of undoped Gd$_3$Al$_x$Ga$_{5-x}$O$_{12}$ (x = 0,1,2,3) and Gd$_2$YAl$_2$Ga$_3$O$_{12}$ mixed crystals were carried out. Mixed crystals composition and lattice parameters were determined using EDX and XRD techniques. [...]

We performed an experiment under long-term microgravity conditions aboard the International Space Station (ISS) to obtain information on the energetics and experimental constraints required for the formation of chondrules in the solar nebula by ’nebular lightning’. As a simplified model system, we exposed porous forsterite (Mg$_2$SiO$_4$) dust particles to high-energetic arc discharges [...]

Accurate simulation of physical processes is crucial for the success of modern particle physics. However, simulating the development and interaction of particle showers with calorimeter detectors is a time consuming process and drives the computing needs of large experiments at the LHC and future colliders. [...]

In the Universe matter outside of stars and compact objects is mostly composed of collisionless plasma. The interaction of a supersonic plasma flow with an obstacle results in collisionless shocks that are often associated with intense nonthermal radiation and the production of cosmic ray particles. [...]

A comparison of PEO layers on Ti6Al4V alloy formed in phosphate, aluminate and silicate-based electrolytes respectively, has been made to reveal the influence of the electrolyte composition on the formation process. The phosphate-based electrolyte has been identified as the most promising one as it has the best coating formation efficiency and the lowest breakdown voltage. [...]

The random nature of self-amplified spontaneous emission (SASE) is a well-known challenge for x-ray core level spectroscopy at SASE free-electron lasers (FELs). Especially in time-resolved experiments that require a combination of good temporal and spectral resolution the jitter and drifts in the spectral characteristics, relative arrival time as well as power fluctuations can smear out spectral-temporal features. [...]

Electron photoinjectors provide high-brightness electron beams to numerous research applications in physics, chemistry, material, and life sciences. Semiconductor photocathodes are widely used here, as they enable the production of low-emittance beams with variable charge at high repetition rates. [...]
