While high-throughput screening for protein crystallization conditions have rapidly evolved in the last few decades, it is also becoming increasingly necessary for the control of crystal size and shape as increasing diversity of protein crystallograp...

We investigate the microstructure evolution of Ag-alloyed PbTe compounds for thermoelectric (TE) applications with or without additions of 0.04 at. % Bi. We control the nucleation and temporal evolution of Ag₂Te-precipitates in the PbTe-matrix applyi...

The goal of this special issue is to obtain new insights into the roles of crystallography in functional materials. This special issue consists of eight papers illustrating the structure and property relationships, as well as applications of selected...

Zn_7/3Sb_2/3O₄ is a secondary phase in ZnO-based varistors. Acceptor impurities, such as Li⁺, increase the resistivity. This effect is produced by a modification of the grain boundary barriers. The role of the cationic distribution in the mentioned eve...

Below $T_{\mathrm{CO}}=157$ K the quasi-one-dimensional charge-transfer salt (TMTTF) ${}_2$ SbF ${}_6$ undergoes a pronounced phase transition to a charge-ordered ground state. We have explored the non-linear and photoconductive behavior as a fun...

A series of LiNi_0.5Mn_1.5O₄ (LNMO) samples were synthesized by adjusting the molar ratio of (NH₄)₂CO₃ to Na₂CO₃ in a mixed precipitant for evaluating the effects of ammonia from (NH₄)₂CO₃ as a complexing agent and Na₂CO₃ as a precipitant on the morpho...

A novel inorganic-organic hybrid supramolecular macrocyclic compound, (4-nitroanilinium)(18-crown-6)(PF₆)(1), was synthesized and characterized by infrared spectroscopy, thermogravimetric analysis, elemental analysis, differential scanning calorimetr...

A newly designed Co(II) complex, [Co₃(L)(OAc)₂(CH₃OH)₂]·CH₃OH, by the reaction of a bis(salamo)-type tetraoxime ligand (H₄L) with Co(II) acetate tetrahydrate was synthesized and characterized by elemental analyses, IR, UV-vis spectra and single-cryst...

This study, using atomic-force and polarized-optical light (AFM and POM) microscopies on the extinction banded spherulites of poly(dodecamethylene terephthalate) (P12T) at high T_c = 110 °C with a film thickness kept at 1–3 µm, has verified that bande...

Here, we investigate the strengths of R–X···π interactions, involving both chlorine and bromine, in model systems derived from protein-ligand complexes found in the PDB. We find that the strengths of these interactions can vary significantly, with bi...

Nanoprobes are one of the most important components in several fields of nanoscience to study materials, molecules and particles. In scanning probe microscopes, the nanoprobes consist on silicon tips coated with thin metallic films to provide additio...

High-quality mixed-cation lead mixed-halide (FAPbI₃)_0.85(MAPbBr₃)_0.15 perovskite films have been prepared using CH₃NH₃Cl additives via the solvent engineering method. The UV/Vis result shows that the addition of additives leads to enhanced absorption...

The solid-state reaction of WO₃ with W was studied in order to clarify the phase formation in the binary system W-O around the composition WO_x (2.50 ≤ x ≤ 3) during spark plasma sintering (SPS). A new phase “WO_2.82” is observed in the range 2.72 ≤ x...

Abstract: As a recycled material, flue gas desulfurization gypsum has been used to prepare calcium sulfate hemihydrate whisker (CSHW) through hydrothermal synthesis for several decades. However, the subsequent utilization of this resultant material h...

Two newly designed complexes, [Zn(L¹)(EtOH)] (1) and [{Zn(L²)(OAc)₂}₂Zn]·CHCl₃ (2) derived from salamo and half-salamo chelating ligands (H₂L¹ and HL²) have been synthesized and characterized by elemental analyses, IR and UV-VIS spectra, fluorescence...

p-Type doping represents a key step towards III-nitride (InN, GaN, AlN) optoelectronic devices. In the past, tremendous efforts have been devoted to obtaining high quality p-type III-nitrides, and extraordinary progress has been made in both material...

A novel ultrathin g-C₃N₄ nanosheet-modified BiOCl hierarchical flower-like plate heterostructure (abbreviated as BC/CN) was constructed via a thermal polymerization of urea precursor followed with hydrolysis route. The as-prepared samples were well c...

Two-dimensional semiconductors, such as transition-metal dichalcogenides (TMDs) and black phosphorous (BP), have found various potential applications in electronic and opto-electronic devices. However, several problems including low carrier mobility...

The growth of single crystalline films (SCFs) with excellent scintillation properties based on the Tb_1.5Gd_1.5Al_5−yGa_yO₁₂:Ce mixed garnet at y = 2–3.85 by Liquid Phase Epitaxy (LPE) method onto Gd₃Al_2.5Ga_2.5O₁₂ (GAGG) substrates from BaO based flux is...

Crystallographic studies frequently involve the determination of a previously unknown crystal structure; General Structure Analysis System (GSAS)-II provides two methods for this purpose. The Monte Carlo/simulated annealing method is fundamentally st...

Polycrystalline Bi₂Se_3−xTe_x (x = 0~1.5) samples were prepared by self-propagating high-temperature synthesis (SHS) combined with spark plasma sintering (SPS) and their thermoelectric properties were investigated. The SHS-SPS process can shorten the t...
