Transducing chemical energy through catalysis by an artificial molecular motor.
Nature

Cells display a range of mechanical activities generated by motor proteins powered through catalysis. This raises the fundamental question of how the acceleration of a chemical reaction can enable the energy released from that reaction to be transduced (and, consequently, work to be done) by a molecular catalyst. Here we demonstrate the molecular-level transduction of chemical energy to mechanical force in the form of the powered contraction and powered re-expansion of a cross-linked polymer gel driven by the directional rotation of artificial catalysis-driven molecular motors.

Realizing quantum control and entanglement of particles is crucial for advancing both quantum technologies and fundamental science. Substantial developments in this domain have been achieved in a variety of systems. In this context, ultracold polar molecules offer new and unique opportunities because of their more complex internal structure associated with vibration and rotation, coupled with the existence of long-range interactions.

Gene expression manipulation is pivotal in therapeutic approaches for various diseases. Non-viral delivery systems present a safer alternative to viral vectors, with reduced immunogenicity and toxicity. However, their effectiveness in promoting endosomal escape, a crucial step in gene transfer, remains limited.

Filamentous plant pathogens pose a severe threat to food security. Current estimates suggest up to 23% yield losses to pre- and post-harvest diseases and these losses are projected to increase due to climate change (Singh et al. 2023; Chaloner et al.

Hybrid molecular ferroelectrics with orientationally disordered mesophases offer significant promise as lead-free alternatives to traditional inorganic ferroelectrics owing to properties such as room temperature ferroelectricity, low-energy synthesis, malleability, and potential for multiaxial polarization. The ferroelectric molecular salt HdabcoClO is of particular interest due to its ultrafast ferroelectric room-temperature switching. However, so far, there is limited understanding of the nature of dynamical disorder arising in these compounds.
