Summary: In this study, the impact of nanoscale forces on the stability of biomolecular condensates is investigated. It is found that condensates with higher surface charge have a lower propensity for fusion, highlighting the role of passive stabilization mechanisms in protecting biomolecular condensates against coalescence.

Summary: Four truxenone derivatives with bulky methoxy substituents were synthesized and studied, showing complex thermotropic behavior compared to truxenones with identical long alkoxy chains. The methoxy groups led to lower clearing points and temperature ranges in the Col(h) phases while maintaining high melting points. Additionally, one derivative self-assembled into a well-ordered two-dimensional structure at a solid/liquid interface resembling a proposed bulk mesomorphic three-dimensional columnar phase.

Summary: A series of new mixed tail triphenylene derivatives with specific side chains were synthesized and characterized, and their liquid-crystalline properties and the effects of variations in the lengths of alkoxy and N-alkyl chains on mesogens were studied. It was found that the length of the alkoxy chains had a more significant impact on the mesogens, and the intermolecular hydrogen bonding induced by the amide functional group enhanced the stability of the mesophase. Additionally, it was discovered that intermolecular hydrogen bonding was not the sole factor responsible for gel formation in these molecules.

Summary: The charge transport in discotic mesogens based on triphenylene core was investigated using the time-of-flight method. The hole mobility was found to decrease with increasing the number of carbon atoms in the alkyl chain attached to the triphenylene core, following an exponential relationship. Dielectric measurements revealed a correlation between molecular ordering and alkyl chain length, impacting hole mobility and permittivity. The potential applications of these compounds in opto-electronics as organic semiconductors are noted, despite the challenge of poor conductivity.

Summary: In this study, a novel core fragment for discotic liquid crystals was discovered, which is composed of an unusual contorted polycyclic aromatic hydrocarbon, Rubicene. The Rubicene derivatives synthesized were thermally stable and showed columnar mesophases at room temperature, as confirmed by polarising optical microscopy, differential scanning calorimetry, and small-angle X-ray scattering.

Summary: Hydrogen-bonded discotic liquid crystals (DLCs) were synthesized through two distinct methods. The first approach introduced a chiral core connected via H-bonding to an achiral system, yielding supramolecular chirality within the columns. In the second method, an achiral core to a chiral system was introduced through H-bonding. Additionally, the peripheral alkyl chain lengths of the DLCs were changed, resulting in temperature-induced transformations in their internal structure.

Summary: In recent years, significant progress has been made in designing new liquid crystalline materials, particularly disc-shaped molecules with rigid π-conjugated structures as active components for electronic devices. A new class of polycyclic aromatic hydrocarbons derived from pyrene core was synthesized and found to exhibit hexagonal columnar mesophase. Pyrene derivatives, widely explored as novel dyes, may find applications in various optoelectronic devices.

Summary: Non-membrane-bound biomolecular condensates are an important mode of subcellular organization, but their spatial organization and dynamics at the atomic level are not well understood. This study combines molecular dynamics simulations with in vitro behavior to analyze the Lge1(1-80) protein condensates. Analysis of protein-protein interactions reveals the key factors in condensate formation and the relationship between configurational entropy, valency, and compactness of proteins inside the condensates. The derived analytical formalism describes condensate architecture across length scales, providing an atomistically resolved model of Lge1(1-80) condensates and their agreement with in vitro morphologies.

Summary: A racemic mixture of chiral molecules can crystallize either as a racemic compound or as a conglomerate of enantiopure crystals. Achiral molecules usually form achiral crystals, but occasionally exhibit chiral structures. The relative energies of chiral and achiral crystals are analyzed, revealing that chiral crystals generally have lower energy when chiral separation occurs on crystallization, while achiral crystals have lower energy when no chiral separation occurs. This analysis suggests that chiral and achiral molecules should be studied together to better understand chirality generation by crystallization.
