We review different models developed to describe this entropy-driven process and the occurrence of cooperative conversions resulting from elastic interactions. There is a growing number of SCO materials exhibiting unusual thermal conversions when symmetry breaking occurs. To illustrate the importance of considering both phenomena, we review studies of the prototype [Fe(ptz)6](BF4)2 system, exhibiting at atmospheric pressure a single step thermal transition with hysteresis, where a ferroelastic distortion occurs from the high-spin high-symmetry (HShs) phase, towards the low-spin low-symmetry (LSls) phase. Under pressure, sequential conversions occur on cooling from the HShs phase towards a high-spin low-symmetry (HSls) phase, followed by a spin crossover towards the LSls phase. In addition, a metastable low-spin high-symmetry (LShs) state forms upon fast cooling. We revisit this coupling and decoupling of spin crossover and ferroelastic phase transition through the Landau theory model adapted by Collet, which provides qualitative agreement with the experimental data, such as the phase diagram and the evolution of spin transition curves or lattice deformations under pressure. This Ferroelastic Instability coupled to Spin Crossover (FISCO) approach should be generalized to many materials undergoing coupled spin transition and symmetry breaking.

The ability to probe motions of the molecule via scattering provides uniquely direct structural information, which, when combined with traditional spectroscopic techniques of comparable temporal resolution, paints a holistic movie of the molecular dynamics. This review aims to provide an introduction to the ultrafast scattering of gas-phase molecules, and to identify the key results and technological breakthroughs that advance our acquaintance of ultrafast molecular dynamics, with a particular focus on the achievements in ultrafast molecular dynamics since the first generation of FEL facilities. We present a brief history of gas-phase ultrafast scattering and the fundamentals of electron- and x-ray scattering, highlighting the complementarity, differences, and bottlenecks of the two experimental scattering methods. We then consider key upgrades in XRS and UED experiments that facilitated the unprecedented spatiotemporal resolution that enabled many of the notable results in the field. Finally, we examine anticipated facility upgrades that address the demand for experimental versatility and enable further developments and exploration.

Here, we review this hybrid method’s applications to the study of copper, silver, and gold atoms and clusters interacting with biological and organic molecules. In particular, we highlight efforts to characterize the relaxation process in a copper(I) phenanthroline complex; details of Cu’s secretory path; the atomic structure of Ag-homopolymers of cytosine and guanine; DNA-stabilized silver clusters; effects related to temperature and solvent on thiolate-protected gold clusters’ optical properties; and the effect of a medium-like noble gas on a cluster’s optical spectrum. The results of these efforts demonstrate how QM/MM methods are applied successfully to a wide range of processes that include the study of excited state evolution, charge transport, light absorption, and emission, and determining an atomic structure in the absence of crystal-determined structure. We expect QM/MM methods will continue supporting the exploration of novel hybrid organo-metallic materials and their safe use in the environment, while also providing guidance on mechanisms to deal with diseases associated with a failure in cells’ proper behavior.

Understanding the relationship of tumors with their microenvironment is also required to understand the tumor progression and metastasis better. Like tumors, the tumor microenvironment (TME) is heterogeneous, offering numerous mechanobiological, mechanochemical, and mechanophysical cues. Biomaterials impersonating extracellular matrix (ECM) properties must provide the mechanical cues cells get from their 3D extracellular environment. Pore size is one imperative yet less studied ECM factor implicated in the invasion and migration of the tumor. Several techniques are used to control the pore size of biomaterials constructed for a distinct tissue. Electrospinning is one of the most steadfast techniques for producing scaffolds with the preferred pore size. A comprehensive interpretation of ECM pore size would contribute toward a better understanding of the reciprocal interaction between pore size and tumor progression and can be used as a promising target for cancer treatments. In this review, we abridged the knowledge pertaining to (1) ECM and pore size, (2) the importance of pore size and its interplay with cancer, and (3) current advancement in the field of biomaterials to study pore size. Overall, this review will cover the effect of pore size on tumor cell behavior concerning electrospinning.

The investigation of the ultrafast charge carriers dynamics resulting from their reduced dimensionality is crucial for guiding the engineering route towards novel nanotechnologies. Here, we first give a brief overview of the state-of-the-art experimental schemes for inspecting the ultrafast response of 2D materials in the THz range, including the generation and the detection of THz light and the prototypical optical pump THz probe setup. Then, we present and discuss the most relevant results, reviewing the THz ultrafast signatures of charge carriers and excitons dynamics in graphene, TMDs, and 2D perovskites.
