The ferromagnetism of ACr5Te8 would be related to long Cr-Cr distances, band structure or itinerancy.
The pseudo-hollandite structure has both 2D and 1D structural aspects.
Two-types (A-type and B-type) of monoclinic C2/m structure for ACr5Te8 are shown in Fig. 1.
Then we prepared Rb0.5Cr5Te8 and found that it has the A-type structure.

Another study employing KOH for activated carbon involves the single-pot graphitization of coconut coir waste with Ni–KOH, producing porous graphitic carbon (PGC) with a high BET surface area (599.414 m2/g) and high order graphitic structure [7].
By reducing the levels of impurities, the HCl pre-treatment ensures a more uniform and controlled reaction environment during pyrolysis, promoting the formation of high-quality graphite structures.

Comparative photocatalytic properties of Cu2O from octahedron to sphere structures Limin Qian1, a ; Jie Zhou1, a ; Chu Zheng1, a ; Di Chen1, a; Bi Shen1, a; Yongkun Liu1,b; Lixiao Wang2,b; and Yanhua Tong1, a * a Department of Materials and Chemistry, Huzhou Teachers College, Huzhou 313000, China.
Cu2O particles with different shapes, such as nanowire, cube, octahedral, multipod, hollow structure and porous spheres, have been synthesized [12-17].
Pentahydrate copper sulfate (II), diethanolamine (HO(CH2)2NH(CH2)2OH), anhydrous sodium sulfite (Na2SO3), the sodium tartrate (Na2C4H4O6·2H2O), solid sodium hydroxide(NaOH), sodium dodecyl benzene sulfonate (C18H29NaO3S), glucose (C6H12O6), were purchased from Aladdin Chemistry Co.Ltd.
In order to investigate photocatalytic characteristics of as-prepared Cu2O with different morphologies, the same Rh 6G solutions were chosen as photocatalytic degradation system and different Cu2O structures with the same mass serve as photocatalysts.

The FESEM images demonstrated that addition of TiO2 could improve the foam structure of the char residue.
A compact and more uniform structure effectively prevents the heat to penetrates into the substrates[19].
In permeation, small molecules and ions of water permeate into pores of coating structure, resulting in weight gain of coating.

Important process information such as biomass and nutrient concentrations are usually off-line measured by conventional wet chemistry techniques, yielding results 0.5 to 8 hours after sampling, which restricts effective process analysis and control.
Biomass measure is also not as good as substrate because of complicate structure in cell and has no obvious absorption peak in spectroscopy.

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering [2].
Sol-gel method has various advantages compared to the other method due to its lower crystallization temperature, ability to tune microstructure via sol-gel chemistry, conformal deposition ability, compositional control and large surface area coating capability [15].

The influence of the amylose/amylopectin ratio on the internal structures and morphologies was able to be revealed by this choice of techniques.
Some of the granules were elongated, filamentous structures with multiple growth directions.
It can be seen that the channel structure differs significantly for the starches with different amylose content.
