Summary: Nanomaterials play a crucial role in human evolution and are deeply integrated into our thinking and application. Unlike conventional micron-filled composites, nanofillers can modify the properties of polymer matrix and introduce new functionality due to their chemical composition and nano dimensions. The advancement of technology drives the need for miniaturized electronic devices, resulting in the widespread presence of electromagnetic fields. The COVID-19 pandemic further accelerates the demand for electromagnetic interference (EMI) shielding as remote working and mobile communication become prevalent. Polymer nanocomposites, as functional materials with versatile properties, have emerged as a promising solution for EMI shielding applications. This review paper provides an overview of nanomaterials-based polymer nanocomposites for EMI shielding.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
