A pressure cell (maximum working pressure of 100 bars) has been developed for neutron scattering experiments at ultralow temperatures (T<100 mK) which makes use of a Bridgman seal design more usually seen in higher temperature experiments in the kilobar range. The large volume of the cell ( approximately 18 cm3) and its construction from a high-strength aluminum alloy make it suitable for inelastic neutron scattering experiments. The cell has been proof tested in operando in search for the supersolid state of helium-4.

Despite extensive research on the use of salts to enhance micellar growth, numerous questions remain regarding the impact of ionic exchange and molecular structure on charge neutralization. This study looks into how certain cations (Na, Ca, and Mg) affect the structure of a cocamidopropyl betaine CAPB and sodium dodecylbenzenesulfonate SDBS surfactant mixture, aiming toward applications in targeted delivery systems. The mixture consists of a zwitterionic surfactant, cocamidopropyl betaine (CAPB), and an anionic surfactant, sodium dodecylbenzenesulfonate (SDBS), combined in varying molar ratios at a total concentration of 200 mM.

The tetragonal heavy-fermion superconductor CeRh_{2}As_{2} (T_{c}=0.3 K) exhibits an exceptionally high critical field of 14 T for B∥c. It undergoes a field-driven first-order phase transition between superconducting states, potentially transitioning from spin-singlet to spin-triplet superconductivity.

The emergence of a quantum spin liquid (QSL), a state of matter that can result when electron spins are highly correlated but do not become ordered, has been the subject of a considerable body of research in condensed matter physics [1,2]. Spin liquid states have been proposed as hosts for high-temperature superconductivity [3] and can host topological properties with potential applications in quantum information science [4]. The excitations of most quantum spin liquids are not conventional spin waves but rather quasiparticles known as spinons, whose existence is well established experimentally only in one-dimensional systems; the unambiguous experimental realization of QSL behavior in higher dimensions remains challenging.

Poly(vinylidene fluoride) (PVDF) is technologically relevant due to its thermal stability; chemical, mechanical and radiation resistance; transparency; biocompatibility; and ease of processing. Several of those applications are related to its high electroactivity, for which the β-phase of the polymer is its most renowned protagonist. In this context, extensive research has been conducted on the crystallization of PVDF in the β-phase, when processed from melt and from solution.
