And is developing to nano-level processing skills.

119 Sn Möss spectroscopy in nanocrystalline aluminat-in composites synthesized by direct grinding and reactive ball milling. G. Le Caër 1, S. Bégin-Colin 1, Y. Calage 2, P. Matteazzi 3 & F. Miani 3 Hyperfine Interactions volume 94, pages 2229–2233 (1994)Cite this article

The particle size distribution and the particle shape were non-homogeneous after another 12 h of grinding. The powder particles are irregularly shaped. 3.2. Hyperfine structure. Möss spectra are used to quantify "hyperfine interactions," which are low-energy interactions between the nucleus and its electrons.

The silica that we use presents a medium hardness, and it becomes hyperfine after around 40 min of colloidal grinding. Olivine on the contrary is harder to grind down to sub-micrometre size, and 150 min of colloidal grinding were required to obtain a majority of grains smaller than 1 μm, as shown in Table 1 .

The hyperfine parameters are summarized in Tables 1 and 2. J o u r n a l P r e -p r o o f are also very close to 2:2:1 reported elsewhere [17][18] [19] [20][21]. The hyperfine parameters for Q2 ...

Syntheses of Fe1−x C x alloys (forx≲0.15) and carbides (for 0.15≲x≲0.50) can be obtained by room temperature grinding of the elemental Fe and C powders. The formation of cementite is completed after about 20 h, whereas the alloys are synthesized in critical processing conditions. Synthesized cementite has a high density of defects and particle size down to 10 nm.

Fe-57 transmission Moess spectroscopy and x-ray diffraction measurements are performed on icosahedral quasicrystals. Magnetic and electronic properties including lattice vibrational states are studied and compared for Al-Cu-Fe and Fe doped Al-Cu-Ge-Mn-type quasicrystalline alloys. In the latter, magnetic long-range order features, most probably ferromagnetism, are revealed …

Inorganic Chemistry 2021, 60, 15, 11154-11163 (Article) Photodynamic therapy (PDT), which involves the photoinduced sensitization of singlet oxygen, is an attractive treatment for certain types of cancer. The development of new photochemotherapeutic agents remains an important area of research.

Grinding (1 min) 2/1. 92–97 d,[14] ... 53 This signal shows varying degrees of resolution of a small 59 Co hyperfine pattern, but the low value of the 59 Co hyperfine splitting and the g-value clearly indicate the majority of the spin-density is located on the corrole ligand.

The magnetic hyperfine field decreased with the ball milling time, from 51.46 down to 50.68 T after 27 h of grinding. Magnetite and traces of iron were observed at the longest milling time employed. The recoilless fraction (f ) was measured simultaneously using a dual Möss absorber consisting of hematite and a stainless steel etalon.
