Dataset of microscopic images and infrared spectra of beach sediment samples from Juara, Salang, and Tulai in Tioman Island, Malaysia.

This dataset presents a comprehensive collection of microscopic images, infrared (IR) spectra of particles obtained from beach sediment in Tioman Island, Malaysia. Sediment samples were collected from multiple sites across three selected beaches to identify material composition and assess the concentration of plastic particles, including both microplastics (<5 mm) and macroplastics (>5 mm), in the region. The IR spectroscopic analysis was carried out in the mid-infrared range (4000-370 cm⁻¹), enabling detailed vibrational characterization of compounds present in the samples.

Dataset of Fourier transform infrared (FTIR) spectra of a primary amine, selected aldehydes, and their Schiff bases acquired using the Invenio-R spectrometer.

This dataset reports on the Fourier-transform infrared (FTIR) spectroscopic analysis of a primary amine and some aldehydes along their corresponding Schiff bases. The dataset presented in this work consists of spectral FTIR data acquired in the 80-6000 cm⁻¹ range, along with the corresponding relative IR intensities of the samples. The primary amine and aldehydes were of high purity and were used to synthesise the corresponding Schiff bases.

Dataset of NIR, MIR, FIR and NMR spectroscopy and GC-MS of real samples of e-liquids from Malaysia.

This dataset presents comprehensive spectroscopic and chromatographic profiling of 27 e-liquid samples including commercial formulations, a booster, and a nicotine solution (the e-liquids were collected in Ampang Jaya, Malaysia before April 2023). Fourier-transform infrared (FTIR) spectroscopy was performed across the near-, mid-, and far-infrared ranges (6000-80 cm), generating unique transmittance spectra for each sample. These spectra revealed vibrational bands characteristic of nicotine, propylene glycol, vegetable glycerine, and various additives, supporting rapid qualitative fingerprinting and comparison through OPUS software.

Treatment of synthetic slaughterhouse wastewater using integrated UV/HO/TiO photocatalytic advanced oxidation process enhanced by yeast-assisted dissolved air floatation.

In treating slaughterhouse wastewater (SWW), conventional treatment processes (CTPs) such as anaerobic processes, membrane processes, and electrocoagulation have various weaknesses, including limited effectiveness, fouling issues, and high energy consumption. Conversely, photocatalytic advanced oxidation processes (PAOPs) have demonstrated superiority over CTPs. However, the treatment effectiveness of PAOPs significantly diminishes when SWW contains high levels of suspended solids (SS).

Aquatic microplastics research in the ASEAN region: Analysis of challenges and priorities.

Research on microplastics must be harmonized. Therefore, we thoroughly evaluated in the Association of Southeast Asian Nations (ASEAN) region, addressing challenges and priorities in protocol harmonization and microplastics research promotion. Of the 615 papers searched by the Web of Science, 164 were used for this systematic review.
