| 1 | Efficient first-principles prediction of solid stability:Towards chemical accuracy显示文摘The question of material stability is of fundamental importance to any analysis of system properties in condensed matter physics and materials science.The ability to evaluate chemical stability,i.e.,whether a stoichiometry will persist in some chemical environment,and structure selection,i.e.what crystal structure a stoichiometry will adopt,is critical to the prediction of materials synthesis,reactivity and properties.Here,we demonstrate that density functional theory,with the recently developed strongly constrained and appropriately normed(SCAN)functional,has advanced to a point where both facets of the stability problem can be reliably and efficiently predicted for main group compounds,while transition metal compounds are improved but remain a challenge.SCAN therefore offers a robust model for a significant portion of the periodic table,presenting an opportunity for the development of novel materials and the study of fine phase transformations even in largely unexplored systems with little to no experimental data. | Yubo Zhang Daniil A.Kitchaev Julia Yang Tina Chen Stephen T.Dacek Rafael A.Sarmiento-Pérez Maguel A.L.Marques Haowei Peng Gerbrand Ceder John P.Perdew Jianwei Sun | 2018 | npj Computational Materials2018，，1： | 7 |
| 2 | Estimating the Parental Magma Composition and Temperature of the Xiaohaizi Cumulate-Bearing Ultramafic Rock: Implication for Magma Evolution of the Tarim Large Igneous Province, Northwestern China显示文摘The ultramafic dikes in the Tarim large igneous province(Tarim LIP), exposed in the Xiaohaizi area in the northwestern Tarim Basin of northwestern China, have porphyritic textures, and the olivine and clinopyroxene are as the major phenocryst phases. The groundmass therein consists of clinopyroxene, plagioclase and Fe-Ti oxides, with the cryptocrystalline texture. The olivine phenocrysts in one typical ultramafic dike have Fo(Mg/(Mg+Fe)) numbers ranging from 73 to 85, which are not in equilibrium with the olivine(Mg# of 89) from the host rock crystalized. Combined with microscope observation, both the olivine and clinopyroxene phenocrysts as well as some Fe-Ti oxides in the ultramafic rock are accounted as cumulates. The liquid(parental magma) composition of SiO_2 of 45.00 wt.%–48.82 wt.%, MgO of 9.93 wt.%– 18.56 wt.%, FeO of 5.85 wt.%–14.17 wt.%, CaO of 7.54 wt.%–11.52 wt.%, Al_2O_3 of 8.70 wt.%–11.62 wt.% and TiO_2 of 0.00 wt.%–3.43 wt.% in the Xiaohaizi ultramafic rock was estimated by mass balance, and the results show a reasonable liquid proportion in the cumulate-bearing ultramafic dike(ca. 45%–60% in the whole rock). The estimated parental magma composition corresponds to a melting temperature of 1 300–1 550 oC, which is equal or higher than those of a normal asthenosphere mantle, supporting the involvement of a mantle plume. Combined with other previous studies, an evolution model for the formation processes of the Xiaohaizi ultramafic dike of the Tarim LIP is proposed. | Haowei Sun Yinqi Li Zilong Li Siyuan Zou Charles H.Langmuir Hanlin Chen Shufeng Yang Zhongyuan Ren | 2016 | Journal of Earth Science2016，27，3： | 2 |
| 3 | Porous polyetheretherketone microcarriers fabricated via hydroxylation together with cellderived mineralized extracellular matrix coatings promote cell expansion and bone regeneration显示文摘Porous microcarriers have aroused increasing attention recently by facilitating oxygen and nutrient transfer,supporting cell attachment and growth with sufficient cell seeding density.In this study,porous polyetheretherketone(PEEK)microcarriers coated with mineralized extracellular matrix(mECM),known for their chemical,mechanical and biological superiority,were developed for orthopedic applications.Porous PEEK microcarriers were derived from smooth microcarriers using a simple wet-chemistry strategy involving the reduction of carbonyl groups.This treatment simultaneously modified surface topology and chemical composition.Furthermore,the microstructure,protein absorption,cytotoxicity and bioactivity of the obtained porous microcarriers were investigated.The deposition of mECM through repeated recellularization and decellularization on the surface of porous MCs further promoted cell proliferation and osteogenic activity.Additionally,the mECM coated porous microcarriers exhibited excellent bone regeneration in a rat calvarial defect repair model in vivo,suggesting huge potential applications in bone tissue engineering. | Shuo Sun Zixue Jiao Yu Wang Zhenxu Wu Haowei Wang Qingming Ji Yi Liu Zongliang Wang Peibiao Zhang | 2021 | Regenerative Biomaterials2021，8，2： | 2 |

| 6 | miR-24-3p promotes proliferation and inhibits apoptosis of porcine granulosa cells by targeting P27显示文摘Ovarian follicle development is associated with the physiological functions of granulosa cells(GCs),including proliferation and apoptosis.The level of miR-24-3p in ovarian tissue of high-yielding Yorkshire×Landrace sows was significantly higher than that of low-yielding sows.However,the functions of miR-24-3p on GCs are unclear.In this study,using flow cytometry,5-ethynyl-2′-de-oxyuridine(EdU)staining,and cell count,we showed that miR-24-3p promoted the proliferation of GCs increasing the proportion of cells in the S phase and upregulating the expression of cell cycle genes,moreover,miR-24-3p inhibited GC apoptosis.Mechanistically,on-line prediction,bioinformatics analysis,a luciferase reporter assay,RT-qPCR,and Western blot results showed that the target gene of miR-24-3p in proliferation and apoptosis is cyclin-dependent kinase inhibitor 1B(P27/CDKN1B).Furthermore,the effect of miR-24-3p on GC proliferation and apoptosis was attenuated by P27 overexpression.These findings suggest that miR-24-3p regulates the physiological functions of GCs. | Shengjie Shi Lutong Zhang Liguang Wang Huan Yuan Haowei Sun Mielie Madaniyati Chuanjiang Cai Weijun Pang Lei Gao Guiyan Chu | 2024 | Journal of Integrative Agriculture2024，23，4： | 0 |
