The evolution of self-organizing ensembles of fullerenes and the emergence of the Buckyball are described by information generating, sharing, and manipulating Source-Reservoir-Sink model. Shannon's information-theoretic model of signal transmitter, channel, and receiver that preserves and retains the original signal is extended to our model that maps the transformations of chemical and physical components of the self-organizing dissipative structures into Source, Reservoir, and Sink. The information generated by Source is manipulated by controlling the flow of information to Reservoir before being transmitted to Sink. It is demonstrated in a Box-model. The role of Reservoir in building up the manipulative capacity for information storage and selective sharing is illustrated by the asymmetric exchange of material and information. The number of boxes and the flow rates are varied to evaluate the information-theoretic diagnostic tools of Shannon entropy, complexity, fractal dimension, relative entropy, and the entropic cost of the emerging dissipative structures.

We propose a double-cavity optomechanical system with nonreciprocal coupling to realize tunable optical nonreciprocity that has the prospect of making an optical device for the manipulation of information processing and communication. Here we investigate the steady-state dynamic processes of the double-cavity system and the transmission of optical waves from opposite cavity directions. The transmission spectrum of the probe field is presented in detail and the physical mechanism of the induced transparency window is analyzed.

Context: SiGe nanotubes (SiGeNTs) hold significant promise for applications in nanosolar cells, optoelectronic systems, and interconnects, where thermal conductivity is critical to performance. This study investigates the effects of length, diameter, temperature, and axial strain on the thermal conductivity of armchair and zigzag SiGeNTs through molecular dynamics simulations. Results indicate that thermal conductivity increases with sample length due to ballistic heat transport and decreases with temperature as phonon scattering intensifies.

The effect of gravity on the collective motion of living microswimmers, such as bacteria and micro-algae, is pivotal to unravel not only bio-convection patterns but also the settling of bacterial biofilms on solid surfaces. In this work, we investigate suspensions of microswimmers under the influence of a gravitational field and hydrodynamics, simulated the dissipative particle dynamics (DPD) coarse-grained model. We first study the collective sedimentation of passive colloids and microswimmers of the puller and pusher types upon increasing the imposed gravitational field and compare them with previous results.

Cutting soft materials on the microscale has emerging applications in single-cell studies, tissue microdissection for organoid culture, drug screens, and other analyses. However, the cutting process is complex and remains incompletely understood. Furthermore, precise control over blade geometries, such as the blade tip radius, has been difficult to achieve.

Spray cooling, which dissipates heat through droplet evaporation, is an efficient cooling method. Using seawater instead of freshwater in spraying is appealing given the intensifying global water crisis. However, seawater-based cooling suffers from salt accumulation on hot surfaces.
