Chemical Compositions and Chromatic Mechanism of High-Temperature Iron-Series Glazed Wares from the Guangyuan Kiln in Sichuan Province, Southwest China During the Song Dynasty.

The Guangyuan kiln, located in the Sichuan Province, Southwest China during the Song Dynasty (960-1279 A.D.), is renowned for its high-temperature iron-series glazed wares, including pure black glazed ware, hare's fur glazed ware, glossy brown glazed ware, and matte brown glazed ware.

TP63 transcriptionally regulates SLC7A5 to suppress ferroptosis in head and neck squamous cell carcinoma.

Background: Most head and neck squamous cell carcinoma (HNSCC) patients are diagnosed at an advanced local stage. While immunotherapy has improved survival rates, only a minority of patients respond durably to targeted immunotherapies, posing substantial clinical challenges. We investigated the heterogeneity of the tumor microenvironment in HNSCC cohorts before and after immunotherapy by analyzing single-cell RNA sequencing (scRNA-seq) data and bulk RNA sequencing datasets retrieved from public databases.

Facile integration of FeS and titanate nanotubes for efficient removal of total Cr from aqueous solution: Synergy in simultaneous reduction of Cr(VI) and adsorption of Cr(III).

In this study, a novel composite composed of iron monosulfide nanoparticles (FeS NPs) and titanate nanotubes (TNTs) was hydrothermally synthesized. Characterizations revealed the encapsulation and homogenous dispersion of FeS NPs into the interlayers of TNTs. Significant performance in removal of aqueous total Cr was acquired by efficient conversion of Cr(VI) to Cr(III) on FeS and simultaneous adsorption of Cr(III) on TNTs.

Araneose Ti self-doping TiO/SiO nanowires membrane for removal of aqueous MB under visible light irradiation.

Araneose Ti self-doped TiO/SiO nanowires (RTiO/SiO) were prepared and anchored onto a polyethersulfone (PES) membrane. Careful characterizations and measurements indicated a covalent grafting of SiO onto reduced TiO (RTiO) through Ti-O-Si linkages, acquiring uniformed RTiO/SiO nanowires of almost complete anatase and benign hydrophilicity. The RTiO/SiO-based PES membrane showed a significantly enhanced visible light-driven degradation rate of methylene blue (MB) (90.

Three-Dimensional Microstructure of ε-FeO Crystals in Ancient Chinese Sauce Glaze Porcelain Revealed by Focused Ion Beam Scanning Electron Microscopy.

Ancient Chinese sauce glaze porcelain has recently received growing attention for the discovery of epsilon iron oxide (ε-FeO) crystals in glaze. In this work, we first confirm the presence of ε-FeO microcrystals, in large quantiteis, in sauce glaze porcelain fired at the Qilizhen kiln in Jiangxi province during the Southern Song dynasty. We then employed focused ion beam scanning electron microscopy (FIB-SEM) to investigate the three-dimensional microstructure of ε-FeO microcrystals, which revealed three well-separated layers (labeled, respectively, as LY1, LY2, and LY3 from the glaze surface to inside) under the glaze surface.

Predicting the onset temperature (T) of GeSe glass transition: a feature selection based two-stage support vector regression method.

Despite the usage of both experimental and topological methods, realizing a rapid and accurate measurement of the onset temperature (T) of GeSe glass transition remains an open challenge. In this paper, a predictive model for the T in GeSe glass system is presented by a machine learning method named feature selection based two-stage support vector regression (FSTS-SVR). Firstly, Pearson correlation coefficient (PCC) is used to select features highly correlated with T from the candidate features of GeSe glass system.

Efficient photoreduction of Cr(VI) on TiO/functionalized activated carbon (TiO/AC-AEMP): improved adsorption of Cr(VI) and induced transfer of electrons.

Slow and random transfer of pollutants and photo-induced carriers on photocatalysts causes loss of efficiency in photodegradation of contaminants. Enhancing and directing mass transfer of them are considered as two major methods for improving the photodegradation of pollutants over photocatalysts. Here in this work, we focused on the design of a novel photocatalyst which not only accelerated the transfer rate of Cr(VI) and electrons but also provided specific transfer routes for them.

Complete mineralization of a humic acid by SO generated on CoMoO/gCN under visible-light irradiation.

The sulfate radical ([Formula: see text]), almost a most active species, is believed to be the best oxidant in the elimination of aquatic organics in advanced oxidation processes. However, acquiring their steady-state generation with high concentration is still challenging work. In this report, we focused on designing a novel composite, in which uniform and rod-like CoMoO was fabricated on gCN through Co-N coordination.

[Effect of Raw Materials and Preparing Process on the Composition of Lime-Ash].

As the saying goes that “no ash, no glaze”, lime-ash has been the core material widely used to prepare glaze in ancient China. Among all the lime-ashes, those made in Jingdezhen are the most influential and representative ones. Not only did lime-ash contribute greatly to the prosperity of porcelain making of Jingdezhen in Song, Yuan, Ming and Qing Dynasty, but also it has a complicated, rigorous and a touch of “mysterious” in its preparation process, technical principle and glaze mechanism.

[Raman and EDXRF Study on Overglaze Decorations of Jingdezhen Ceramics].

Overglaze decoration porcelain is an important category of ancient Chinese ceramics, which has significant artistic value and scientific value. Nondestructive analysis methods such as Raman spectroscopy and EDXRF were used to analyze the overglaze decorations on the Jingdezhen ceramic samples of Yuan, Ming and Qing Dynasty. The recipe and color mechanism of the overglaze pigments were discussed according to the chemical composition and phase composition analysis.

[Chemical composition and chromaticity characteristic of purple-gold glaze of Jingdezhen imperial kiln].

Color glaze is one of the four famous traditional ceramics of Jingdezhen, especially for the products from Ming and Qing Dynasties' official kilns which have rich connotation of technology and culture. The chemical composition and chromaticity characteristic of glaze and body of purple-gold glaze samples from Jingdezhen Ming and Qing Dynasties' official kilns were analyzed by energy dispersive X ray fluorescence (EDXRF) and colorimeter. Preliminary study on the composition, formula and chromaticity characteristic of glaze of purple-gold glaze samples of different period was carried out and the intrinsic causes of ifferences were discussed.

[Research on the composition characteristics of imitated Longquan celadon in Jingdezhen and Longquan celadon].

Longquan celadon not only has been loved widely by the domestic and international ceramic lovers, but also imitated by the kiln workers from different places. Among all of the imitated celadons, the most representative products appeared in Ming and Qing dynasties. This paper used EDXRF to test 38 pieces of Longquan celadon of Song, Yuan and Ming dynasty and imitated Longquan celadon in Jingdezhen of Ming dynasty, combined with firing temperature in order to analyze the different composition characteristics of the bodies and the glaze, evolution rule and formation reasons of these samples in the two different places from the views of time and space.

[Chemical composition and chromaticity characteristic of Jilan glaze of Ming and Qing official kilns].

Color glazes of Ming and Qing official kilns are excellent representatives of the famous ancient Chinese porcelains. The study of official ware with Jilan glaze has been an important topic. But it made slow progress due to the rarity of samples with strict production management and using system.

[Research on the composition characteristics of Chinese ancient southern white porcelain].

The southern white porcelain is the rise in our country's pottery, it is later than the development of northern white porcelain, but it is rising stars, blockbuster, well-grounded, keeping continuous. Jingdezhen kiln and Dehua kiln are the most representative kilns among the southern white porcelain kilns. the present paper used EDXRF to test 30 pieces of Song, Yuan and Ming period' Dehua white porcelains and Jingdezhen Yuan dynasty Shufu white porcelains samples to analyze the different characteristics of the bodies and the glaze of these samples in terms of time and space.
