This work demonstrated that Cd doping at the Bi site converts n-type AgBiSe2 to p-type. The hole concentration is effectively increased with increasing Cd doping content, thereby enhancing the electrical conductivity. Theoretical calculations reveal that Cd doping flattens the edge of the valence band, resulting in an increase in the density-of-states effective mass and Seebeck coefficient. A record-high power factor of ~ 6.2 µW⋅cm−1⋅K−2 was achieved at room temperature. Furthermore, the induced dislocations enhance the phonon scattering, contributing to the ultralow lattice thermal conductivity across the entire temperature range. As a result, a decent figure of merit (zT) of ~ 0.3 at room temperature and a peak zT of ~ 0.5 at 443 K were obtained in AgBi0.92Cd0.08Se2.

Understanding its physical mechanisms is essential for obtaining high-quality crystals. Typically, crystals grown by thermal evaporation or sublimation nucleate the substrate facing the evaporation source. Here, a novel vapor micro-turbulence mass transport mechanism in the growth process of ultrathin BiOCl single crystals has been revealed. In this mechanism, the precursor vapor bypasses the solid substrate, forming micro-turbulent vaporizing flows to nucleate on the surface of the substrate facing away from the evaporation source. Considering nucleation kinetics, fast shear flows are known to cause secondary nucleation, increasing nucleation quantity while decreasing the final size of the crystals. Thus, the nucleation and growth process of BiOCl crystals are controlled by adjusting the micro-turbulence intensity to reduce shear flow energy and dilate phase distribution, resulting in BiOCl crystals with uniform distribution and regular shape. Subsequent structural and morphological characterization confirms the high crystallization quality of the obtained crystals, and the performance of the constructed solar-blind photodetectors is comparable to that of similar devices. These findings contribute to a deeper understanding of vapor mass transport and crystal growth techniques and may be useful for applications related to metal oxide crystals.<h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"43 11","pages":"5921 - 5931"},"PeriodicalIF":9.6,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyoxometalates (POMs) are a class of molecular anion metal oxide clusters with well-defined structures and diverse properties. Therefore, the design and synthesis of a POM-based material for proton conduction is extremely vital. Herein, a dimeric four tartaric acid-bridged tetra-Zr-incorporated arsenotungstate, [NH2(CH3)2]16KH7[{Zr(tarH) O2}4{As2W19O68}2]·16H2O (1) (tarH = tartaric acid), was successfully synthesized via a conventional aqueous method that utilized the tartaric acid ligand protection strategy, and it was systematically characterized by powder X-ray diffraction (PXRD), thermo gravimetric analysis (TGA), infrared (IR), ultraviolet (UV) spectra and energy-dispersive X-ray spectroscopy (EDS). This strategy included an innovative [Zr(tarH)WO2]48+ core sandwiched by two distorted [As2W19O68]16− subunits. The [Zr(tarH)WO2]48+ core is constituted of four Zr4+ and four {WO2} groups, which are linked together by four tartaric acid ligands. Interestingly, the four tartaric acid ligands decorated on Zr4+ are covalently modified toward the W atoms. Moreover, the impedance measurements demonstrate that 1 has excellent proton conduction properties with the proton conductivity value of 3.82 × 10−3 S·cm−1 under 348 K and 95% RH. <h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"33 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

N-integrated carbon dioxide (CO2) co-reduction has gained a lot of attention from the scientific community, particularly in recent years, and is considered a promising approach to turn waste into wealth and achieve carbon neutrality and a nitrogen cycle. In this review, a comprehensive review of the catalytic coupling of CO2 and nitrogenous small molecules (such as N2, NH3 and NOx) for the green synthesis of high-value chemicals is presented, including representative urea, amines, and amides. In these advances, in-depth discussions of C−N coupling are critically evaluated from the standpoints of catalyst design strategies and possible reaction mechanisms, highlighting the key factors and descriptors that affect the catalytic performance.

The effect of Sm addition on the plastic deformation mechanism of Mg-Gd-Y-Zr (GW) alloy was investigated, and a detailed analysis was conducted on the relationships between mechanical responses and the microstructure of the alloys. The findings suggest that dislocation slip plays a predominant role in the plastic deformation of GW-(Sm) alloys. The addition of Sm reduces the stacking fault energy (SFE) of the alloy, which promotes < c + a > slip and inhibits twinning. Meanwhile, Sm plays a role in solution strengthening, causing an elevation in the flow stress of the alloy. At cryogenic temperature (CT), the critical resolved shear stress (CRSS) of dislocation slip is increased, so the dislocation motion requires greater external force. In addition, the extensive crossed twins exhibited in the microstructure, which shorten the dislocation slip path and enhance the grain boundary strengthening.

Therefore, the development of fast response and low detection limit acetone sensors becomes crucial. In this study, a core-shell spherical TiO2 sensor with a rich pore structure was designed. This sensor exhibited excellent sensing properties, including higher responsiveness (100 ppm acetone, Ra/Rg = 80), lower detection limit (10 ppb) and short response time (8 s). The problem is that the sensing mechanism between TiO2 and acetone is not thoroughly analyzed. To gain further insight, the interaction process of TiO2 core-shell spheres and acetone under varying oxygen content environments was investigated by dynamic testing, X-ray photoelectron spectroscopy, in-situ Fourier transform infrared spectroscopy and gas chromatography-mass spectrometry. The research results show that acetone not only adsorbs on the surface of the material and reacts with adsorbed oxygen, but also undergoes catalytic oxidation reaction with TiO2 core-shell spheres. Significantly, in high oxygen content environments, acetone undergoes oxidation to form intermediates such as acids and anhydrides that are difficult to desorpt on the surface of the material, thus prolonging the recovery time of the sensor. The discovery of this sensing process will provide some guidance for the design of acetone sensing materials in the future. Meanwhile, this also imparts valuable references and insights for the investigation of the mechanism and application of other sensitive metal oxide materials.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"8 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142209098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
