The equilibrium phase behaviour [1-3] are presented for the concentrated suspension of bacteriophage fd, DNA-viruses charged DNA-viruses, at sufficiently low ionic strengths (below 1 mM Tris/HCl buffer), which is a good model system for highly charged colloidal rods, exhibiting the phase transitions; from the nematic-to-chiral nematic and other hierarchical chiral-mesophases (Xpattern and helical domains) to the glass states, in an increase of the rod-concentration [4-5]. In this talk, experiments on both equilibrium and the field-induced phase transition, as well as sheer response of the glass state in flow will be discussed. [...]

Structurally, the mineral clinoatacamite Cu$_2$Cl(OH)$_3$ is closely related to the kagome material herbertsmithite Zn$_3$CuCl$_2$(OH)$_6$. In clinoatacamite, however, the kagome motif of Cu sites is embedded into a low-symmetry crystal structure, which causes a distortion of the kagome plane as well as different site symmetries for the kagome Cu sites.

Quantum magnets with geometrical frustration stand out due to their highly degenerate ground states and their susceptibility to be tuned by applying pressure or magnetic field. Such tuning can lead to quantum phase transitions from ordered to disordered states, or vice versa, with the emergent quantum critical points (QCPs) determining the deformed entropy landscapes in the respective phase diagrams. [...]

POLI is a hot neutron two-axis diffractometer at the Heinz Maier-Leibnitz Zentrum (MLZ), Germany, which uses spin-polarized neutrons for magnetic studies in particular. The instrument is used, for instance, to study complex crystal and magnetic structures, to reconstruct magnetization densities in the unit cell, and to explore phase diagrams of materials via multiparameter studies. [...]

We present evidence for the presence of a field-induced quantum critical point (QCP) at 21.9(1) T (H || c axis) in the frustrated quantum magnet atacamite Cu$_2$Cl(OH)$_3$, a mineral which we have recently identified as a material realization of sawtooth chains [J ~ 336 K (basal-basal), J' ~ 102 K (basal-apical)]. Residual interchain couplings lead to long-range antiferromagnetic order in atacamite below $T_\mathrm{N}$ = 8.9(1) K. [...]

Hydroponic cultivation is commonly used in plant physiology studies; however, studies involving soil are rare.The response of 3 monocotyledonous and 3 dicotyledonous species to cultivation in soil compared with that to cultiva-tion in hydroponic solution was investigated along with the quantification of relevant morphological parameters. The rootanatomy was studied with the help of histochemical and microscopic analyses. [...]

The push for a more circular economy worldwide has necessitated further research into direct recycling. There are many waste streams that currently do not have a possible direct recycling route developed. [...]
