Key Topics

The construction of nanostructured materials with advanced functions by the self-organization of molecular building blocks is one of the key topics in modern materials chemistry. This review describes our concept of the hierarchical design of polyoxometalate (POM)-based compounds with nanosized spaces: (1) syntheses of building blocks (POMs and counter cations), (2) directing the self-organization of building blocks to form crystalline materials with nanosized spaces, and (3) kinetic control of the self-organization process to introduce nanosized space into the dense nonporous crystal, with emphasis on (2). Our recent results on the construction of nanosized spaces within the POM-based compounds with controlled size, volume, shape, and affinity, and their functions are presented.

Current Task

The current task of the molecular sciences is to create unique nanostructured materials with a given structure and with specific physicochemical properties on the basis of the existing wide range of molecules of natural and synthetic origin. A promising and inexpensive way to obtain nanostructured materials is the spontaneous self-assembly of molecular building blocks during random collisions in real dispersive systems in solution and at interfaces. This editorial aims to summarize the major points from the 11 scientific papers that contributed to the special issue “The Self-Assembly and Design of Polyfunctional Nanosystems”, assessing the modern self-assembly potential and strategies for maintaining sustainable development of the nanoindustry.

The promotion of new and competitive industries through cross-sectoral inter-organizational collaborations are tackled in many regions globally. This study explores the management of facilitating collaboration with consideration of the planned approach to change based on change management theory. The “initial conditions,” “field,” and “emerging interaction toward the collaborations” are clarified as key elements for management through intervention. It is considered how these interventions are implemented on these elements. A conceptual model for considering comprehensive management of the self-organization process toward collaboration is proposed. In the case study, experiences of the medical technology industry of three German states are examined. The activities of cluster organizations of these states, which provide services to facilitate cross-sectoral collaborations, are scrutinized. The results of the case study are comparatively analyzed, and the modified conceptual framework is depicted by reflecting the findings of the study. The implications are then discussed.

Комплексно исследовано влияние дневного освещения на процесс самоорганизации в цистеин-серебряном растворе (ЦСР) и гидрогелях на его основе. Установлено, что ЦСР на основе L-цистеина и ацетата серебра под действием освещения окрашивается сначала в желтый, а затем в коричневый цвет, что является следствием плазмонного резонанса на образующихся наночастицах серебра (НЧС) в ЦСР и гидрогелях. Предложена модель формирования НЧ в гидрогеле. The effect of daylight on the self-assembly process in cysteine-silver solution (CSS) and hydrogels based on it has been comprehensively studied. It was found that CSS based on L-cysteine and silver acetate under the action of illumination first turns yellow and then brown, which is a consequence of plasmon resonance on the resulting silver nanoparticles in CSS and hydrogels. A model for the formation of silver nanoparticles in a hydrogel is proposed.

We study non-equilibrium spatial self-organization in cold atomic gases, where long-range spatial order spontaneously emerges from fluctuations in the plane transverse to the propagation axis of a single optical beam. The self-organization process can be interpreted as a synchronization transition in a fully connected network of fictitious oscillators, and described in terms of the Kuramoto model.

Single-stranded DNA–melamine hybrid molecular building blocks were synthesized using a phosphoramidation cross-coupling reaction with a zero linker approach. The self-assembly of the DNA–organic hybrid molecules was achieved by DNA hybridization. Following self-assembly, two distinct types of nanostructures in the form of linear chains and network arrays were observed. The morphology of the self-assembled nanostructures was found to depend on the number of DNA strands that were attached to a single melamine molecule.
