| 1 | Discovery and Significance of Diamonds and Moissanites in Chromitite within the Skenderbeu Massif of the Mirdita Zone Ophiolite,West Albania显示文摘In recent years diamonds and other unusual minerals(carbides,nitrides,metal alloys and native elements) have been recovered from mantle peridotites and chromitites(both high-Cr chromitites and high-Al chromitites) from a number of ophiolites of different ages and tectonic settings.Here we report a similar assemblage of minerals from the Skenderbeu massif of the Mirdita zone ophiolite,west Albania.So far,more than 20 grains of microdiamonds and 30 grains of moissanites(SiC) have been separated from the podiform chromitite.The diamonds are mostly light yellow,transparent,euhedral crystals,200~300 μm across,with a range of morphologies;some are octahedral and cuboctahedron and others are elongate and irregular.Secondary electron images show that some grains have well-developed striatums.All the diamond grains have been analyzed and yielded typical Raman spectra with a shift at ~1325 cm^(-1).The moissanite grains recovered from the Skenderbeu chromitites are mainly light blue to dark blue,but some are yellow to light yeUow.All the analyzed grains have typical Raman spectra with shifts at 766 cm^(-1),787 cm^(-1),and 967 cm^(-1).The energy spectrums of the moissanites confirm that the grains are composed entirely of silicon and carbon.This investigation expands the occurrence of diamonds and moissanites to Mesozoic ophiolites in the Neo-Tethys.Our new findings suggest that diamonds and moissanites are present,and probably ubiquitous in the oceanic mantle and can provide new perspectives and avenues for research on the origin of ophiolites and podiform chromitites. | WU Weiwei YANG Jingsui MA Changqian MILUSHI Ibrahim LIAN Dongyang TIAN Yazhou | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 10 |
| 2 | Diamond Discovered in High-Al Chromitites of the Sartohay Ophiolite,Xinjiang Province,China显示文摘In recent years diamonds and other exotic minerals have been recovered from mantle peridotites and high-Cr chromitites of a number of ophiolites of different age and different tectonic environments. Here we report a similar collection of minerals from the Sartohay ophiolite of Xinjiang Province,western China,which is characterized by having high-Al chromitites. Several samples of massive podiform chromitite with an aggregate weight of nearly 900 kg yielded diamonds,moissanite and other highly reduced minerals,as well as common crustal minerals. Thus far,more than 20 grains each of diamond and moissanite have been recovered from heavy mineral separates of the chromitites. The diamonds are all 100-200 μm in size and range in color from pale yellow to reddish-orange to colorless. Most of the grains are anhedral to subhedral octahedra,commonly with elongate forms exhibiting well-developed striations. They all display characteristic Raman spectra with shifts between 1325 cm-1 and 1333 cm-1,mostly 1331.51 cm-1 or 1326.96 cm-1. The moissanite grains are light blue to dark blue,broken crystals,50-150 μm across,commonly occurring as small flakes or fragments. Their typical Raman spectra have shifts at 762 cm-1,785 cm-1,and 966 cm-1. This investigation extends the occurrence of diamonds and moissanite to a Paleozoic ophiolite in the Central Asian Orogenic Belt and demonstrates that these minerals can also occur in high-Al chromitites. We conclude that diamonds and moissanite are likely to be ubiquitous in ophiolitic mantle peridotites and chromitites. | TIAN Yazhou YANG Jingsui Paul T.ROBINSON XIONG Fahui LI Yuan ZHANG Zhongming LIU Zhao LIU Fei NIU Xiaolu | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 9 |
| 3 | Obesity pandemic in China:epidemiology,burden,challenges,and opportunities显示文摘China faces a substantial burdensome pandemic of obesity.Recent data from the Chinese Centre for Disease Control and Prevention suggested that over an estimated 8.1%of Chinese adults(85 million Chinese adults)had obesity in 2018,which was three times the level in 2004.[1]To understand the trends of overweight and obesity in China,we accessed the country/territory-level year-specific data of age-standardized summary exposure value(SEV,standing for the pooled proportion among the population),deaths,and disability-adjusted life of years(DALYs)for high body mass index(BMI,high BMI was defined as the BMI level higher than theoretical minimum risk exposure level[25 kg/m2])and its associated diseases for 204 countries/territories between 1990 and 2019 using data from the Global Burden of Disease Collaborative Network.[2]Previous literature described detailed methods for the data synthesis.[3,4]Using the country/territory-level data by year,we calculated the estimated annual percentage changes(EAPCs)with 95%uncertainty intervals(UI)to estimate the annual changing patterns of age-standardized SEV,death,and DALY rates among 204 countries/territories.To compare statistics from China and other regions,we calculated the corresponding estimates from regions including global,North Africa and Middle East,Sub-Saharan Africa,Western Pacific Region,European Union,Latin America and Caribbean,and South Asia. | Jing Li Qingyang Shi Qingyang Gao Xiong-Fei Pan Li Zhao Yazhou He Haoming Tian Zhiming Zhu Sheyu Li | 2022 | Chinese Medical Journal2022，，11： | 3 |
| 4 | Jurassic granitoid dike in Luodian, Guizhou Province: discovery and geological significance显示文摘In this paper, the Jurassic granitoid dike that intrudes into Permian diabase was reported in Luokun,Luodian County, south Guizhou. Zircon LA-ICP-MS U–Pb dating of the granitoid dike yielded an age of 164.3 ± 2.4 Ma with the e Hf(t) range from + 7.8 to + 12.1. The high contents of SiO_2(65.2%–66.8%) and total alkali(Na_2O + K_2O: 9.01%–9.95%), and low contents of Mg, Fe, Ca, P and Ti show the characteristics of alkali-rich granite. The total contents of rare earth elements range from 289.90 to 394.23 ppm. The Rb, Ba, K, Th, U and other LILE, Ta, Sr, P, Ti are enriched, and heavy rare earth elements are depleted. Petrogeochemical characteristics show that the dike was derived from a partial melting of newly-grown basaltic crust, and contaminated by crustal materials before experiencing strong fractional crystallization. The dike was formed in the intraplate post-orogenic extension stage and indicates that parental magma rose to the shallow crust through a fault. This provides new evidence of tectonic and mantle-crust magmatic activities and may contribute to regional Au mineralization in southern Guizhou and neighboring areas. | Mingjin Zhu Aiguo Nie Yazhou Tian Xinsong Wang Jun Sun | 2019 | Acta Geochimica2019，38，1： | 2 |

| 6 | Photocatalytic water splitting on BiVO_(4):Balanced charge-carrier consumption and selective redox reaction显示文摘Surficial redox reactions play an essential role in photocatalytic water splitting,and are closely related to the surface properties of a specific photocatalyst.In this work,using monoclinic BiVO_(4)decahedral single crystals as a model photocatalyst,we report on the interrelationship between the photocatalytic activity and the surficial reaction sites for charge-carrier consumption.By controlled hydrothermal synthesis,the ratio of{010}to{110}facets on BiVO_(4),which respectively serve as reductive and oxidative sites,is carefully tailored.Our results show that superior photocatalytic water oxidation could be obtained on BiVO_(4)decahedrons with a medium ratio of reductive/oxidative sites and that efficient overall water splitting could be achieved via further modification of appropriate cocatalysts in Z-scheme system.The excellent photocatalytic performance is attributed to the accelerated selective redox reactions by realizing balanced charge-carrier consumption,which provides insightful guidance for prospering photocatalytic reactions in energy conversion. | Xiangjiu Guan Li Tian Yazhou Zhang Jinwen Shi Shaohua Shen | 2023 | Nano Research2023，16，4： | 1 |
| 7 | The Janus-faced role of Piezo1 in cardiovascular health under mechanical stimulation显示文摘In recent years,cardiovascular health problems are becoming more and more serious.At the same time,mechanical stimulation closely relates to cardiovascular health.In this context,Piezo1,which is very sensitive to mechanical stimulation,has attracted our attention.Here,we review the critical significance of Piezo1 in mechanical stimulation of endothelial cells,NO production,lipid metabolism,DNA damage protection,the development of new blood vessels and maturation,narrowing of blood vessels,blood pressure regulation,vascular permeability,insulin sensitivity,and maintenance of red blood cell function.Besides,Piezo1 may participate in the occurrence and development of atherosclerosis,diabetes,hypertension,and other cardiovascular diseases.It is worth noting that Piezo1 has dual effects on maintaining cardiovascular health.On the one hand,the function of Piezo1 is necessary to maintain cardiovascular health;on the other hand,under some extreme mechanical stimulation,the overexpression of Piezo1 may bring adverse factors such as inflammation.Therefore,this review discusses the Janus-faced role of Piezo1 in maintaining cardiovascular health and puts forward new ideas to provide references for gene therapy or nanoagents targeting Piezo1. | Junyang Huang Kun Zhang Ruolin Du Wanling Liu Haijun Zhang Tian Tian Yazhou Wang Guixue Wang Tieying Yin | 2023 | Genes & Diseases2023，10，5： | 1 |
| 8 | Diamonds, Super-Reduced and Crustal Minerals in Chromitites of the Hegenshan and Sartohay Ophiolites, Central Asian Orogenic Belt, China显示文摘The Central Asian Orogenic Belt(CAOB)is a huge tectonic mélange that lies between the North China Craton and the Siberian Block.It is composed of multiple orogenic belts,continental fragments,magmatic and metamorphic rocks,suture zones and discontinuous ophiolite belts.Although the Hegenshan and Sartohay ophiolites are separated by nearly 3000 km and lie in completely different parts of the CAOB,they are remarkably similar in many respects.Both are composed mainly of serpentinized peridotite and dunite,with minor gabbro and sparse basalt.They both host significant podiform chromitites that consist of high-Al,refractory magnesiochromite with Cr#s[100Cr/(Cr+Al)]averaging<60.The Sartohay ophiolite has a zircon U-Pb age of ca.300 Ma and has been intruded by granitic plutons of similar age,resulting in intense hydrothermal activity and the formation of gold-bearing listwanites.The age of the Hegenshan is not firmly established but is thought to have formed in the Carboniferous.Like many other ophiolites that we have investigated in other orogenic belts,the chromitites in these two bodieshave abundant diamonds,as well as numerous super-reduced and crustal minerals.The diamonds are mostly,colorless to pale yellow,200-300μm across and have euhedral to anhedral shapes.They all have low carbon isotopes(δ14C=-18 to-29)and some have visible inclusions.These are accompanied by numerous super-reduced minerals such as moissanite,native elements(Fe,Cr,Si,Al,Mn),and alloys(e.g.,Ni-Mn-Fe,Ni-Fe-Al,Ni-Mn-Co,Cr-Ni-Fe,Cr-Fe,Cr-Fe-Mn),as well as a wide range of oxides,sulfides and silicates.Grains of zircon are abundant in the chromitites of both ophiolites and range in age from Precambrian to Cretaceous,reflecting both incorporation of old zircons and modification of grains by hydrothermal alteration.Our investigation confirms that high-Al,refractory chromitites in these two ophiolites have the same range of exotic minerals as high-Cr metallurgical chromitites such as those in the Luobusa ophiolite of Tibet.These collections of exotic minerals in ophiolitic chromitites indicate complex,multi-stage recycling of oceanic and continental crustal material at least to the mantle transition zone,followed by uprise and emplacement of the peridotites into relatively shallow ophiolites. | Paul T.ROBINSON YANG Jingsui TIAN Yazhou ZHU Huang | 2017 | Acta Geologica Sinica(English Edition)2017，91，S1： | 0 |
| 9 | Comparative tribological behavior of friction composites containing natural graphite and expanded graphite显示文摘In this study, expanded graphite and natural graphite were introduced into resin-based friction materials, and the tribological behavior of the composites was investigated. The tribo-performance of the two friction composites was evaluated using a constant speed friction tester. The results showed that the expanded graphite composite (EGC) displayed better lubricity in both the fading and the recovery processes. The wear rate of the EGC decreased by 22.43%more than that of the natural graphite composite (NGC). In the fading process, and the EGC enhanced the stability of the coefficient of friction. The recovery maintenance rate of the NGC was 4.66% higher than that of the EGC. It can be concluded that expanded graphite plays an important role in the formation of a stable contact plateau and can effectively reduce the wear. | Hongyun JIN Keke ZHOU Zhengjia JI Xiaocong TIAN Ying CHEN Luhua LU Yazhou REN Chunhui XU Shanshan DUAN Jiangyu LI Shu-en HOU | 2020 | Friction2020，8，4： | 0 |
