“…Arodur 460.9 methyl diphenyl di-isocyanate (MDI, NCO content = 30.5-31.5%, viscosity in the range of 170-210 mPa s at 25 °C) was supplied by Pozzi Arosio (Italy). Zeolite 4A (CAS n°70 955-01-0, Sigma Aldrich, Italy), whose chemical composition was reported elsewhere, [43,44] consisting of particles with [45] size in the range of 0.5-5 μm, [46] was used as filler.…”

World cultural heritage is an invaluable resource and must be preserved. Conventional packaging materials, such as polystyrene‐PS, polyurethane (PU) foams, paper‐like tissue, and nylon fabric, are petrol‐based. According to Agenda 2030, and Green Deal directives, the development of alternative bio‐based materials has gained significant scientific and technological relevance. In this scenario, a new sustainable packaging material for safe storage and transporting of the artifacts, based on a sustainable PU foam filled with 6 wt.% of Zeolite 4A, is herein proposed. Zeolite 4A dispersion into PU matrix imparts higher compression strength and energy absorption capability with respect to unloaded materials (7‐fold increase), owing to its remarkable cell nucleating effect. The proposed foam can adsorb water vapor, up to 29 wt.%, thus contributing to regulating the humidity around the artifact. A remarkable advantage of the developed foam is the possibility to use it as plaster for precisely casting the article to protect, resulting in strongly improved handling, protection, and transportation safety with respect to conventional packaging solutions. A proof‐of‐concept workflow is proposed, consisting of: i) 3D scanning of the original artifact, ii) its replication through 3D printing, iii) the use of such replica to prepare a tailored cast of the artifact shape.This article is protected by copyright.

“…Because these ions are free to move, the ion exchange that occurs depends on the size and charge, as well as the type of zeolite. The properties of zeolite as an ion exchanger depend on the type of cation, temperature, and type of anion [56].…”

Pemanfaatan karbon aktif (activated Carbon) sebagai adsorben dalam berbagai aspek penilitian mengalami peningkatan yang sangat pesat dari tahun ke tahun (Nwabanne, et al, 2011). Karbon Aktif sebagai absorben tidak lagi asing bagi kehidupan kita, pemanfaatan karbon aktif dapat kita temukan mulai dari hal yang paling kecil dalam kehidupan rumah tangga, di dunia kesehatan, dan juga di Industri- industri besar baik dalam pemisahan maupun untuk penyimpanan gas. Besarnya kebutuhan terhadap penggunaan karbon aktif sebagai absorben tidak di barengi dengan produksi karbon aktif di negeri ini. Kita masih mengandalkan negara luar sebagai pemasok kebutuhan karbon aktif, sedangkan ketersediaan bahan dasar untuk pembuatan karbon aktif di Indonesia sangat berlimpah dan tidak terjamahkan sama sekali.Karbon aktif dapat didefinisikan sebagai bahan karbon dengan struktur amorf dan luas permukaan internal yang besar dengan tingkat porositas yang tinggi. Karbon aktif memiliki bentuk karbon mikrokristalin dan non-grafit. Bentuk non-grafit berarti terdiri dari sejumlah kecil hidrogen atau sejumlah besar oksigen dalam strukturnya. Karbon aktif memiliki kinerja tinggi dalam konduktivitas listrik, stabilitas termal yang baik, serta reaktivitas permukaan yang menjadi alasan utama karbon aktif digunakan dalam beberapa tahun terakhir.

“…Materials exhibiting a ratio greater than 3 are categorised as high silica zeolites or zeolite Y. These high silica zeolites have good physical and chemical stability as well as hydrophobicity [41] . When the ratio is less than 3, it is called zeolite X or low-silica zeolites.…”

Microporous structures have attracted significant attention in recent years. In particular, metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have received considerable attention due to their tailorable structures that offer a wide range of choices in terms of molecular building blocks. Due to their high tunability, these materials are considered as ideal host matrices for templating and encapsulating guest materials, particularly quantum dots (QDs). QDs are investigated heavily for various applications such as light-emitting diodes (LED), biosensors, catalysts, and solar cells due to their unique properties from the quantum confinement effect. However, one of the drawbacks of QDs is their tendency to aggregate and exhibit low stability due to their small size and kinetic trapping in nanoparticle form. This perspective highlights promising approaches to enhance the performance and stability of QDs by using microporous materials as an encapsulation layer. Additionally, potential mitigating strategies are discussed to overcome current challenges and improve the practicality of QDs embedded in microporous nanocomposites.
