“…This was done to avoid the self-discharge phenomenon observed when redox species are mixed with the electrolyte. The MB interacted with rGO sheets through hydrogen bonding (À OÀ H•••N), [19,147] electrostatic interaction, and π-π stacking process to form a very stable electrode system that retained 81.0 % capacitance in the flexible solid-state device after 10,000 charging-discharging cycles. Figures 5C and 5D show the MB-rGO supramolecular synthesis process and corresponding capacitance values.…”

“…[12][13][14][15][16][17][18] Covalent and ionic bonding make the molecules rigid, limiting their structural flexibility and mobility. [19,20] However, these reversible bonds allow them to exhibit regeneration/self-healing properties along with structural flexibility and mobility. [18,21] Such unique self-healing characteristics of the supramolecular entities are highly desirable for energy-storage devices because they can address issues relating to sustainability and stability of the supercapacitor (SC) devices with high energy and power densities.…”

As the world moves towards renewable and sustainable energy sources, the need for systems that can quickly and safely store this energy is also rising. Supercapacitors (SCs) are among the most promising alternatives to conventional lithium‐ion batteries. SCs are more stable, have higher‐power densities, and can be charged much faster. However, SCs have their issues, and three of the main drawbacks of current SCs are 1) lower energy densities, 2) high cost of production, and 3) safety concerns in wearable devices. In this review, we discuss recent progress made in supramolecule‐based SCs (SSCs). In supramolecular systems, molecules are held stable using non‐covalent‐type bonds. This allows for a flexible system in which the molecular interaction sites can easily break and reform at low energy, allowing for exposure of highly active sites and self‐healing. When heterometal atoms are introduced into these supramolecular systems, this allows for further activation of the metal sites through the metal‐metal interaction along with the metal‐ligand interactions. This review discusses different types of SSCs (carbon‐based and metal‐incorporated) that have been utilized in recent years depending on their synthesis process. The working principle of SSCs and the utilization of different supramolecular elements that enhance the performance of SCs have also been discussed.

“…It is well established that triazine based materials are strongly basic in nature with their point zero charge above the pH 7. [63][64][65] Triazoles, amines and imines are the other materials which are strongly basic in nature. [66,67] Thus, purposely introducing such groups to the skeleton will help in designing CO 2 -philic materials.…”

Covalent organic frameworks (COFs) are a promising class of porous crystalline materials made up of covalently connected and periodically protracted network topologies through organic linkers. The tailorability of organic linker and intrinsic structures endow COFs with a tunable porosity and structure, low density, facilely‐tailored functionality, and large surface area, attracting increasing amount of interests in variety of research areas of membrane separations. COF‐based membranes have spawned a slew of new research projects, ranging from fabrication methodologies to separation applications. Herein, we tried to emphasis the major developments in the synthetic approaches of COFs based membranes for a variety of separation applications such as, separation of gaseous mixtures, water treatment as well as separation of isomeric and chiral organic compounds. The proposed methods for fabricating COF‐based continuous membranes and columns for real world applications are also thoroughly explored. Finally, a viewpoint on the future directions and remaining challenges for COF research in the area of separation is provided.

LLDPE is a less crystalline polymer with vast industrial and domestic applications. It is imperative to understand the synthesis, processing conditions, and thermal degradation mechanism of the co- as well as terpolymers. This paper reports the in−situ synthesis and thermal degradation studies of the ethylene-propylene copolymer and ethylene-propylene-1-hexene terpolymer and its nanocomposite with ZnAL LDH sheets. The 1-hexene dosing during the in−situ process influenced the product yield and immensely affected the thermal stability of the resultant polymer. One milliliter 1-hexene in−situ addition increased the product yield by 170 percent, while the temperature at 10 percent weight loss in TGA was dropped by about 60 °C. While only 0.3 weight percent ZnAL LDH addition in the terpolymer improved the thermal stability by 10 °C. A master plot technique and combined kinetics analysis (CKA) were deployed to access the thermal degradation mechanism of the synthesized polymers.
