... Despite significant progress in nanomaterials, the quest to discover and characterize new 2D systems with novel physical and chemical properties continues [22]. Our group recently proposed the Irida-Graphene (Irida-G), a new carbon-based nanomaterial [23], which has since been the focus of several studies [24][25][26][27][28]. Initially, we described Irida-G as having a flat structure composed of 3, 6, and 8-membered rings, with no buckling and a cohesive energy of -7.0 eV/atom. ...
Recently, a new 2D carbon allotrope called Irida-Graphene (Irida-G) was proposed. Irida-G consists of a flat sheet topologically arranged into 3-6-8 carbon rings exhibiting metallic and non-magnetic properties. In this study, we investigated the thermal transport properties of Irida-G using classical reactive molecular dynamics simulations. The findings indicate that Irida-G has an intrinsic thermal conductivity of approximately 215 W/mK at room temperature, significantly lower than that of pristine graphene. This decrease is due to characteristic phonon scattering within Irida-G's porous structure. Additionally, the phonon group velocities and vibrational density of states for Irida-G were analyzed, revealing reduced average phonon group velocities compared to graphene. The thermal conductivity of Irida-G is isotropic and shows significant size effects, transitioning from ballistic to diffusive heat transport regimes as the system length increases. These results suggest that while Irida-G has lower thermal conductivity than graphene, it still holds potential for specific thermal management applications, sharing characteristics with other two-dimensional materials.

Nanotechnology has developed as a groundbreaking field with enormous potential for a wide range of applications, including biotechnology, medicine, and environmental cleanup. One intriguing use is encasing bacteria in nanomaterials to improve and control their biological functions. In order to modify the biological functions of bacteria, various forms of nanomaterials are employed to encapsulate them. Through the goal of utilizing bacteria-encased nanoparticles for targeted drug delivery, bioremediation, and biotherapeutic interventions, researchers have been investigating various nanomaterials in recent years.

Energy storage and conversion systems have emerged as a crucial component with the development of numerous electronic devices, enabling the devices to function for extended periods of time.

A biopolymer is a polymer produced by living organisms. However, they can also include synthetic polymers synthesized by humans from biological sources, such as vegetables oils, amino acids, proteins, resins, fats and sugars. Their biocompatibility, bio absorption, and degradation property make them widely used in different fields. Complete biodegradation of biopolymers leads to the formation of CO2 and water. However, some biopolymers are difficult to degrade naturally because they can require specific parameters like temperature, pressure, relative humidity, a specific microorganism, an industrial-grade composter and can take up to 6 months or more. Nanomaterials have unique thermophysical, optical, and mechanical properties that have been found to influence the degradability of biopolymers. A variety of nanoparticles can be used to improve the physicochemical stability and degradability of materials. Bionanocomposites are the next-generation materials and have been studied extensively for the last few decades. As biopolymer-nanocomposites are becoming a mainstay of advanced polymer research, their suitability under various environmental conditions and their degradation rate after their operational life are also important aspects of research. Thus, the current review will focus mostly on the effect of nanoscale materials on the degradation behavior of biopolymers and the critical comparison among several nanomaterials. In addition, several issues regarding biopolymer degradation and the scope of possible research work have also been discussed.
Nanostructures synthesised by hard-templating assisted methods are advantageous as they retain the size and morphology of the host templates which are vital characteristics for their intended applications. A number of techniques have been employed to deposit materials inside porous templates, such as electrodeposition, vapour deposition, lithography, melt and solution filling, but most of these efforts have been applied with pore sizes higher in the mesoporous regime or even larger. Here, we explore atomic layer deposition (ALD) as a method for nanostructure deposition into mesoporous hard templates consisting of mesoporous silica films with sub-5 nm pore diameters. The zinc oxide deposited into the films was characterised by small-angle X-ray scattering, X-ray diffraction and energy-dispersive X-ray analysis.
