“…[61][62][63] However, on some occasions at low angles of scattering, the data for solvated gels can sometimes be fitted to an appropriate model. For example, the scattering data obtained from a gel can be modelled as a collection of cylinders or tapes and the output from this fitting can provide useful information about nanoscale dimensions, such as the cylinder diameter.…”

Molecular gels represent a case of hierarchical self-assembly of low molecular weight compounds into well ordered fibrillar architectures through non-covalent interactions. The resulting nanomaterials have found applications in multiple fields. In order to facilitate these applications, detailed study of their self-assembly mechanisms and properties at different length scales is required. The hierarchical nature of these materials means that a wide and multidisciplinary set of techniques have been developed and applied for the fundamental study of molecular gels. Different techniques are optimal for characterising aspects of the gel on each length scale – molecular, nano, microscopic and macroscopic. The present chapter uses selected examples to describe the different techniques that have been applied so far for a complete characterization of these systems. In particular, we focus on spectroscopy for probing molecular assembly, microscopy & diffraction/scattering to probe the nanoscale structuring, and calorimetric & rheological studies to provide insight into macroscopic performance. This chapter also focuses on aspects of gel characterisation such as chirality, kinetics and solvent effects.

“…The rays are scattered by the sample, and the complex patterns produced by the scattered light are analyzed to investigate the structure of hard and soft matter systems down to the atomic level [ 157 ]. This non-destructive method can be applied to various sample types, from crystals to complex biological molecules [ 158 ]. X-ray scattering experiments can employ several X-ray sources, from X-ray tubes and rotating anodes to synchrotron radiation.…”

Microfluidics has emerged as a robust technology for diverse applications, ranging from bio-medical diagnostics to chemical analysis. Among the different characterization techniques that can be used to analyze samples at the microfluidic scale, the coupling of photonic detection techniques and on-chip configurations is particularly advantageous due to its non-invasive nature, which permits sensitive, real-time, high throughput, and rapid analyses, taking advantage of the microfluidic special environments and reduced sample volumes. Putting a special emphasis on integrated detection schemes, this review article explores the most relevant advances in the on-chip implementation of UV–vis, near-infrared, terahertz, and X-ray-based techniques for different characterizations, ranging from punctual spectroscopic or scattering-based measurements to different types of mapping/imaging. The principles of the techniques and their interest are discussed through their application to different systems.

“…The small angle X‐ray scattering (SAXS) is used to determine the crystalline structure of polymers coated microcapsule/nanocapsule at a range of 0.02° to 10° . The wide angle X‐ray scattering (WAXS) or wide angle X‐ray diffraction (WAXD) is used to measure the crystalline structure of inorganic‐ and organic polymeric–encapsulated materials at wider angles at 2 θ > 1°.…”

The micro‐/nano‐PCMs for thermal energy storage systems: A state of art review

et al. 2019

Summary With advancement in technology—nanotechnology, various thermal energy storage (TES) materials have been invented and modified with promising thermal transport properties. Solid‐liquid phase change materials (PCMs) have been extensively used as TES materials for various energy applications due to their highly favourable thermal properties. The class of PCMs, organic phase change materials (OPCMs), has more potential and advantages over inorganic phase change materials (IPCMs), having high phase change enthalpy. However, OPCMs possess low thermal conductivity as well as density and suffer leakage during the melting phase. The encapsulation technologies (ie, micro and nano) of PCMs, with organic and inorganic materials, have a tendency to enhance the thermal conductivity, effective heat transfer, and leakage issues as TES materials. The encapsulation of PCMs involves several technologies to develop at both micro and nano levels, called micro‐encapsulated PCMs (micro‐PCM) and nano‐encapsulated PCMs (nano‐PCM), respectively. This study covers a wide range of preparation methods, thermal and morphological characteristics, stability, applications, and future perspective of micro‐/nano‐PCMs as TES materials. The potential applications, such as solar‐to‐thermal and electrical‐to‐thermal conversions, thermal management, building, textile, foam, medical industry of micro‐ and nano‐PCMs, are reviewed critically. Finally, this review paper highlights the emerging future research paths of micro‐/nano‐PCMs for thermal energy storage.
