Partikel nano TiO2 berbasis air dengan pH basa telah berhasil disintesis dengan menggunakan metode sol-gel dan diimobilisasi pada kain kapas dengan menggunakan kitosan sebagai zat pengikat silang. Sintesis dilakukan  dengan prekursor TiCl4 pada konsentrasi 0,3 M, 0,5 M dan 1 M, dan menggunakan templat kanji dengan proses kalsinasi pada suhu 500˚C selama 2 jam. Partikel nano TiO2 diaplikasikan ke kain kapas dengan metoda pad-dry-cure dan menggunakan kitosan sebagai crosslinking agent. Berdasarkan hasil Scanning Electron Microscope (SEM),diketahui bahwa morfologi partikel TiO2 berbentuk spherical dengan ukuran nano (kurang dari 100 nm). Karakterisasi X-Ray Diffraction (XRD) menunjukkan adanya tiga tipe struktur kristal utama, yaitu (100), (101) dan (102) dengan fasa kristal yang terbentuk adalah anatase dan rutile. Pada karakterisasi menggunakan SEM terhadap serbuk dari TiO2 yang telah diaplikasikan ke permukaan kain kapas, terlihat adanya imobilisasi partikel nano TiO2 melalui ikatan hidrogen silang dengan kitosan pada kain kapas. Hasil analisa tersebut kemudian dikonfirmasi dengan FTIR (Fourier Transform Infra Red) yang hasilnya memperlihatkan puncak serapan pada bilangan gelombang 3495 cm-1, 2546 cm-1, dan 511 cm-1,  yang masing-masing diasumsikan sebagai adanya vibrasi gugus fungsi O-H, N-H dan Ti-O-Ti. Hasil SEM menunjukkan pula bahwa kristal nano yang terbentuk diantaranya adalah fasa rutile , yang berdasarkan literatur terbukti dapatberfungsi sebagai anti UV.

Abstract Quaternary semiconductor Cu2NiSnS4 thin film was made by the sol-gel method associated to dip-coating technique on ordinary glass substrates. In this paper, we have studied the impact of dip-coating cycle at different cycles: 4, 5 and 6 on the structural, compositional, morphological, optical and electrical characteristics. CNTS thin films have been analyzed by various characterization techniques including: X-ray diffractometer (XRD), Raman measurements, scanning electron microscope (SEM), energy dispersive X-ray spectroscope (EDS), UV-visible spectroscopy and four-point probe method. XRD spectra demonstrated the formation of cubic Cu2NiSnS4 with privileged orientation at (111) plane. Crystallite size of cubic CNTS thin films increase with from 6.30 to 9.52 with dip-coating cycle augmented. Raman scattering confirmed the existence of CNTS thin films by Raman vibrational mode positioned at 332 cm− 1. EDS investigations showed near-stoichiometry of CNTS sample deposited at 5 cycles. Scanning electron microscope showed uniform surface morphologies without any crack. UV-visible spectroscopy indicated that the optical absorption values are larger than 104 cm− 1, Estimated band gap energy of CNTS absorber layers decrease from 1.64 to 1.5 eV with dip-coating cycle increased. The electrical conductivity of CNTS thin films increase from 0.19 to 4.16 (Ω cm)-1. These characteristics are suitable for solar cells applications.

Tongkol jagung merupakan limbah agrikultural yang banyak mengandung silika yang pemanfaatannya belum maksimal. Silika dai tongkol jagung dapat menjadi solusi alternatif untuk menggantikan sumber silika komersial. Penelitian ini bertujuan untuk mengisolasi, mensintesis, dan mengkarakterisasi zeolit silikalit-1 dari limbah tongkol jagung.

AbstrakPerovskite manganit merupakan salah satu rekayasa material yang dapat menghasilkan perubahan fenomena fisika. Telah berhasil dibuat material berbasis perovskite manganit Nd0,6Sr0,4MnO3 menggunakan metode sol-gel¬ dan dikompositkan dengan ZnO (Nd0,6Sr0,4MnO3)1-x/(ZnO)x (x = 0; 0,3; 0,5; 0,7). Hasil pengujian X-Ray Diffraction menunjukkan sampel Nd0,6Sr0,4MnO3 berstruktur tunggal ortorombik dan sampel ZnO pada (Nd0,6Sr0,4MnO3)0,5/(ZnO)0,5 berstruktur heksagonal tunggal. Hasil pengujian Field Emission Scanning Electron Microscope menunjukkan sampel telah homogen dengan rata-rata ukuran butir 0,188 μm. Hasil pengujian Vibrating Sample Magnetometer menunjukkan sampel (Nd0,6Sr0,4MnO3)0,5/(ZnO)0,5 bersifat paramagnetik dan mengalami penurunan sifat magnetik juga suseptibilitas seiring dengan penambahan konsentrasi material ZnO. AbstractPerovskite manganite is one of the manipulation materials that can produce changes in physical phenomena. Perovskite material Nd0,6Sr0,4MnO3 has been made with the sol-gel method and then composites with ZnO (Nd0.6Sr0.4MnO3)1-x/(ZnO)x (x = 0; 0.3; 0.5, 0, 7). The results of the X-Ray Diffraction characterization test showed samples of Nd0,6Sr0,4MnO3 and ZnO each with a single orthorhombic phase with a Pnma space group and a single hexagonal with a P63mc space group. The results of the Field Emission Scanning Electron Microscope characterization test showed that the samples were homogeneous with an average grain size of 0,188 μm. Vibrating Sample Magnetometer characterization test results show composite material (Nd0,6Sr0,4MnO3)1-x/(ZnO)x are paramagnetic and the increasing composition of ZnO material decreases the magnetization and susceptibility value of sample

Pentrary alloys of Cu2Zn1-xCdxSnS4 nanostructures have been grown on glass substrate using sol-gel technique. The concentration of Cd has showed obvious effect for characterization study. Field emission-scanning electron microscope (FE-SEM) and atomic force microscope (AFM) have provide nanostructures of the utilized alloys. Those alloys give good impression about increasing the grain size with Cd concentration increasing, that lead to increasing the surface coarse.

Abstract A scanning electron microscope equipped with a wavelength dispersive spectrometer and an energy dispersive analyzer was used to examine paint chips and glasses. Line profiles of the elements in the paint show the non-uniform distribution of the pigments and extenders and, in order to obtain reproducible intensity ratios, a large area of the sample must be scanned. Layer analysis of the paint chip is possible with the energy dispersive analyzer and the resulting elemental profiles can be used to identify the chips. The difference in sodium concentration among the glasses studied provides a means of identifying the glass, but care must be taken to avoid migration of the sodium ions in the glass during electron beam bombardment.
