“…Simultaneous analysis of the spectra with the software code VINDA allowed the sextets structure to be resolved into a sextet due to probe Fe ions located at the Fe sites in the BFO and BBFO lattice (Fe$_{BFO}$) and a broad magnetic distribution due to Fe at defect sites such as oxygen vacancies. The main focus of the study was the temperature-dependent behaviour of the magnetic field at the Fe sites in the undoped and Ba-doped samples (Fe$_{BFO}$). …”

“…The enhanced electrochemical performance of Co(3)O(4) nanostructures prepared using the milky sap of CP could be attributed to the surface oxygen vacancies, a relatively high amount of Co(2+), the reduction in the optical band gap and the fast charge transfer rate. …”

“…Raman spectroscopy showed characteristic bands corresponding to NiFe(2)O(4) with a shift of the A(1g) mode, which may be due to possible development of oxygen vacancies. Dielectric constant, measured at different temperatures, increased with temperature and decreased with increase in frequency at all temperatures. …”

“…When the oxygen ions from H(2)O fill the inherent O vacancies of the brownmillerite structure, one of the water protons remains in the same layer (O3) while the second proton is located in the neighboring layer (O2) in sites with partial occupancies, as previously demonstrated by Jayaraman et al. …”

“…Subtraction of the PDF of crystalline Na(x)Sb phases from the total PDF, an approach constrained by chemical phase information gained from (23)Na ssNMR in reference to relevant model compounds, identifies two previously uncharacterized intermediate species formed electrochemically; a-Na(3–x)Sb (x ≈ 0.4–0.5), a structure locally similar to crystalline Na(3)Sb (c-Na(3)Sb) but with significant numbers of sodium vacancies and a limited correlation length, and a-Na(1.7)Sb, a highly amorphous structure featuring some Sb–Sb bonding. …”

“…Temperature dependent Seebeck coefficient measurements indicate that the nanocrystalline AgCuS does not display the p–n–p type conduction switching property like its bulk form, but remains p-type throughout the measured temperature range due to the presence of excess localized Ag vacancies. Nanocrystalline AgCuS exhibits a wider electronic band gap (∼1.2 eV) compared to that of the bulk AgCuS (∼0.9 eV), which is not sufficient to close the band gap to form a semimetallic intermediate state during the orthorhombic to hexagonal superionic phase transition, thus AgCuS nanocrystals do not show conduction type switching properties like their bulk counterpart. …”

“…METHODS: To understand the implications of different CBA approaches for capturing and monetising benefits and their potential impact on public health decision-making, we conducted a CBA of human papillomavirus (HPV) vaccination in the United Kingdom using eight methods for monetising health and economic benefits, valuing productivity loss using either (1) the human capital or (2) the friction cost method, including the value of unpaid work in (3) human capital or (4) friction cost approaches, (5) adjusting for hard-to-fill vacancies in the labour market, (6) using the value of a statistical life, (7) monetising quality-adjusted life years and (8) including both productivity losses and monetised quality-adjusted life years. …”

“…In response to 7‒9-year prey abundance cycles, annual frequency of territory occupancy by breeders was highly variable and low overall with monotonic increases in vacancies through low prey years. Occupancy of territories by breeders differed from random; some appeared preferred while others were avoided, producing a right-skewed distribution of total territory-specific fledgling production. …”

“…Moreover, I(G) was reduced more than one order of magnitude in HfAlO(X) MOS-HEMT by the N(2) surface plasma treatment, due to reduction of N(2) vacancies which were created by ICP dry etching. The N(2) plasma treated Γ-shaped gate HfAlO(X)-based MOS-HEMT exhibited a decent performance with I(DMAX) of 870 mA/mm, G(MMAX) of 118 mS/mm, threshold voltage (V(TH)) of −3.55 V, higher I(ON)/I(OFF) ratio of approximately 1.8 × 10(9), subthreshold slope (SS) of 90 mV/dec, and a high V(BR) of 195 V with reduced gate leakage current of 1.3 × 10(−10) A/mm.…”

“…The outline of the overall study describes the superior photocatalytic performance of 5.0 wt % MoS(2)–TiO(2) nanocomposite which is ascribed to the delayed recombination by efficient charge transfer, high surface area, and elevated surface oxygen vacancies. The context of the obtained results designates that the sensitization of TiO(2) with MoS(2) is a very efficient nanomaterial for photocatalytic applications.…”

“…In view of the approximate relaxation activation energy (~1 eV) calculated from Z″ and M″ peaks, the dielectric relaxation process of the BGTN−0.2Cr ceramic was suggested to be dominated by the thermally activated motion of oxygen vacancies as defect charge carriers. Finally, a high piezoelectricity of d(33) = 18 pC/N as well as a high resistivity of ρ(dc) = 1.52 × 10(5) Ω cm at 600 °C provided the BGTN−0.2Cr ceramic with promising applications in the piezoelectric sensors with operating temperature above 600 °C.…”
