Summary: The Zenghou Yi Tomb from 433 BC is an important archaeological find from the early Warring States Period in China. The tomb contained a significant amount of lacquerware, with red, black, and yellow patterns. Analysis of the lacquered inner coffin and zither indicate that the lacquer samples have multilayered structures and contained added eggs and oil. The differences in pigments used for the red, black, and yellow patterns may explain the rarity of yellow painted lacquerware from early periods.

Summary: By analyzing the materials and techniques used in the Tian Di Chang Chun horizontal plaque, it was found that the decorative layer consists of a red lacquer film layer and a ground layer. The red lacquer film layer is made of Chinese lacquer, tung oil, and cinnabar, while the ground layer is composed of blood putty, youman, and brick powder. The technique used is the San Dao Hui layer technique commonly found in ancient buildings. This study provides physical evidence and technical support for the protection and restoration of inscribed plaque relics.

Summary: In this study, diagnostic research was conducted on a precious Yuan dynasty tomb mural painting excavated in Chongqing in 2005. Analysis of the painting technique and preservation state was done using various methods such as optical microscope, portable X-ray fluorescence, micro-Raman spectroscopy, macro-Fourier transform infrared spectroscopy, and X-ray powder diffraction. The composition of coarse ground and fine ground was determined, as well as the pigments and binders used for the painting layers. The study also revealed the use of protein as a binder and organic additive in the mural painting.

Summary: Three artworks by Brazilian painter Tarsila do Amaral, created in different artistic phases, were analyzed using macro X-ray fluorescence scanning. Elemental maps were used to deduce the pigments employed by the artist. XRF spectra were simulated and compared with experimental data to analyze the presence of lead and zinc pigments in different layers. The study concludes that Tarsila consistently used the same pigments but exhibited changes in painting style.

Summary: In this study, the atomistic-level mechanism for the chemical passivation of the monocrystalline Si surface with thermally annealed Al2O3 was investigated using in situ infrared spectroscopy and photoconductance decay measurements. The results showed that surface Si-H bonds are preserved after the ALD of Al2O3 on H-terminated Si, and restructuring occurs at the c-Si/Al2O3 interface during annealing to form interfacial SiOx. Isotope labeling was used to differentiate interfacial SiD bonds on the c-Si surface from H incorporated in Al2O3, and no net migration of atomic H or D from Al2O3 to the c-Si/Al2O3 interface was observed within the sensitivity of the infrared setup. Passivation studies were also conducted on c-Si/SiO2/Al2O3 stacks, revealing that an O-2-containing atmosphere led to the best surface chemical passivation.

Summary: The development of stimuli-responsively degradable porous carriers for controlled drug release is important for clinical translation. In this study, a new type of Fe-MOF nanocrystals is engineered as an acid-degradable drug carrier and hydrogen donor. Fe-MOF nanocrystals exhibit acid-responsive degradation for H-2 generation and simultaneous drug release, and can effectively inhibit cancer metastasis and sensitize MDR cancer cells for enhanced chemotherapy. The high anti-MDR/antimetastasis efficacies and biocompatibility make Fe-MOF nanocrystals and Fe-MOF-based nanomedicine highly promising for clinical translation.

Summary: This study used various techniques to analyze ancient food remains discovered in the Changle Cemetery in Ningxia, China. The results revealed that the cereal foods were baked cakes made primarily from foxtail millet, with the addition of barley flour and meat from cattle and chicken. This suggests the adoption of grinding and baking technologies in the region during the Han Dynasty, as a result of migration and the opening of the Silk Road. Additionally, the study identified dried beef and the earliest scientific evidence of mutton kebab in ancient China.

Summary: A concept of sonocatalytic hydrogen/hole-combined 'inside/outside-cooperation' anti-biofilm is proposed for efficient eradication of biofilm. The concept involves the use of two-dimensional piezoelectric nanomaterials to promote bacteria-infected diabetic wound healing by inhibiting bacterial energy metabolism and destroying the bacterial membrane/electron transport chain. In vivo experiments have shown that this sonocatalytic therapy significantly improves bacteria-infected diabetic wound healing, making it a promising strategy for deep-seated biofilm infection treatment.

Summary: Ceramic raptors resembling eagles were discovered at the Shimao site in Shaanxi, China. Noninvasive analysis of their composition suggests that they were made from clay different from that of the surrounding soil. The ceramic raptors were likely produced by multiple units, intended to mimic a culturally significant bird species, and used in special events before being intentionally discarded.

Summary: The metabolic disorder in NAFLD leads to the formation of an iron pool, causing ferroptosis and liver disease deterioration. Researchers have discovered that free heme in the iron pool can catalyze the hydrogenation of H2O2/‧OH, blocking the heme-based Fenton reaction. They have developed a hepatocyte-targeted hydrogen delivery system to prevent the vicious cycle of liver disease. This nanomedicine improves liver function by relieving oxidative stress, preventing ferroptosis, and accelerating the removal of the iron pool.

Summary: Tumor heterogeneity poses challenges for drug penetration in solid tumors. In this study, a novel strategy of US-driven piezoelectrocatalytic tumor immunoactivation was proposed, which involved piezoelectrocatalytic hydrogen generation and lactic acid deprivation. The experiments on an orthotopic liver cancer model demonstrated that intratumoral piezoelectric SnS nanosheets (SSN) generated hydrogen and deprived lactic acid, leading to the liberation of effector CD8(+) T cells and activation of tumor immunity. This strategy achieved a high outcome of liver tumor therapy with complete tumor eradication and 100% mice survival.
