“…As illustrated in Figure 1 , CNPs were synthesized according to published works [ 18 , 19 ] by carbonizing the date palm fronds at 400 °C for approximately 3 h, followed by high-energy ball milling for 15 h with a rotating speed of 200 rpm; the metallic jar contained four metallic balls of equal weight. The obtained carbon soot weighed around 25 g. Next, carbon powder was poured into DI water and mixed with a magnetic stirrer for 24 h at 70 °C; then, larger carbon particles were allowed to settle down, and the solution was filtered.…”

Numerous studies have been reported on single- and multicolored highly fluorescent carbon nanoparticles (FCNPs) originating from various sources and their potential applications in bioimaging. Herein, multicolored biocompatible carbon nanoparticles (CNPs) unsheathed from date palm fronds were studied. The extracted CNPs were characterized via several microscopic and spectroscopic techniques. The results revealed that the CNPs were crystalline graphitic and hydrophilic in nature with sizes ranging from 4 to 20 nm. The unsheathed CNPs showed exemplary photoluminescent (PL) properties. They also emitted bright blue colors when exposed to ultraviolet (UV) light. Furthermore, in vitro cellular uptake and cell viability in the presence of CNPs were also investigated. The cell viability of human colon cancer (HCT-116) and breast adenocarcinoma (MCF-7) cell lines with aqueous CNPs at different concentrations was assessed by a cell metabolic activity assay (MTT) for 24 and 48 h incubations. The results were combined to generate dose-response curves for the CNPs and evaluate the severity of their toxicity. The CNPs showed adequate fluorescence with high cell viability for in vitro cell imaging. Under the laser-scanning confocal microscope, the CNPs with HCT-116 and MCF-7 cell lines showed multicolor fluorescence emissions, including blue, green, and red colors when excited at 405, 458, and 561 nm, respectively. These results prove that unsheathed CNPs from date palm fronds can be used in diverse biomedical applications because of their low cytotoxicity, adequate fluorescence, eco-friendly nature, and cheap production.

“…To avoid the contamination problem, the jars and balls were coated with hard ceramic materials. This technique mechanically deforms the solid sample into very fine nanomaterials in powder form [36]. A diagram of the manufacturing setup for the graphitic biochar production (GB2, GB5, GB10) and milled biochar (BMGB2, BMGB5, BMGB10) is shown in figure 1.…”

The valorisation of waste from rose-based industrial products produces value-added substances and paves the way for advanced composites. The rose waste generated from the essential oil industry of the Taif rose (Rosa damascena trigintipetala Dieck) is significant, and its management or disposal is a source of concern. In this study, it was valorised to produce a value-added nanomaterial. The synthesis of biochar nanoparticles via high-energy ball milling has gained tremendous research interest in recent times because of its low cost and eco-friendliness. Ball milling is a solvent-free technology with strong potential for waste volatilisation and eco-sustainability through the production of engineered biochar nanoparticles. Different biochar samples were produced and characterised to harness the synergistic combination of biochar production and ball milling. They were prepared at a constant pyrolysis temperature of 300oC by varying the pyrolysis times for 2 h, 5 h, and 10 h. The characterisation results showed that pyrolysis confirms a high content of carbon, minerals, graphitic structure, novel morphology and chemical characteristics attached to the biochar surface controlled by different pyrolysis durations. These properties were further enhanced by ball milling for 10 h. The results showed that ball milling enhanced the porosity, surface area, surface functional groups, visible light absorption, crystallinity, and carbon content, and these were accompanied by a reduction in the particle size and mineral impurities. The engineered biochar can be an important tool, with promising potential in novel composites for water purification and energy harvesting.

Sifat nano partikel karbon menyerupai sifat nano partikel pada semikonduktor anorganik sehingga menjadikan material berbahan karbon tersebut berpeluang untuk menggantikan maupun digunakan secara bersama-sama dengan semikonduktor anorganik dalam pengaplikasiannya (Khan et al, 2017).…”

Penelitian ini bertujuan untuk menentukan sifat optik, energi pergeseran Stokes, energi celah pita (Eg), gugus fungsi senyawa kimia dan ukuran karbon nano partikel atau Carbon Nanoparticles (CPNs). Sifat optik terdiri dari absorbansi dan intensitas flouresens yang dihasilkan oleh metode sintesis hidrotermal (150, 160, dan 180) ºC. Panjang gelombang absorbansi dan intensitas flouresens terdeteksi dengan metode spektroskopi UV-Vis (396.31, 399.61, dan 411.24) nm dan eksitasi laser 405 nm untuk emisi flouresens (524.18, 512.04, dan 510.92) nm. Energi pergeseran Stokes diperoleh berdasarkan perbedaan energi foton untuk ekesitasi (absorbansi) dan emisi (flouresen) dengan nilai (0.59, 0.55 dan 0.69) eV. Energi celah pita (Eg) ditentukan dengan mengekstrapolasi grafik ke rentang linier untuk memotong sumbu energi foton. Nilai Eg adalah (2.55, 3.43, dan 2.50) eV. Spektrum dan nilai koefisien ekstensi (k), konduktivitas optik (σopt) meningkat sedangkan indeks bias (n) menurun sering bertambahnya suhu hidrotermal. Spektrum FT-IR dan ukuran CNPs dilakukan dengan menggunakan sampel suhu 180 ºC. Gugus fungsi kimia yang terbentuk adalah C-H, C-N, N=C=S, O=C=O serta senyawa Nitrogen (NO2). Ukuran rata-rata nano partikel karbon adalah 11.09 nm berdasarkan intensitas (%), volume (%) dan nomor (%) partikel pada sampel CNPs.
