| 1 | DEGREE OF SUBSTITUTION OF THE IONIZED STARCHES AND THEIR ADHESIVE CAPACITY TO POLYESTER / COTTON FIBERS显示文摘Adhesive capacity of quaternary ammonium starch and starch phosphate to the polyester / cotton fibers was studied by means roving method for the purpose of improving the sizing performance and decreasing the cost. By introducing different amount of quaternary ammonium or phosphate groups onto starch molecules, the modified starch with a series of defferent degree of substitution was prepared. Therefore the regularity of adhesive capacity, extended property and size-absorbing ability with the change in degree of substitution (DS) was obtained through the researches. The experiments demonstrate that the DS of the two modified starches show a marked influence upon the properties mentioned above. The starch phosphate is superior to quaternary ammonium starch as warp size for polyester / cotton yarns from the viewpoint of adhesive capacity and cost, although both of them are better than natural one. To improve the adhesive capacity to polyester / cotton fibers, DS≥0.027 is necessary for quaternary ammonium | 祝志峰 卓仁禧 | 1997 | Journal of China Textile University(English Edition)1997，14，1： | 19 |
| 2 | The genome sequence of celery(Apium graveolens L.),an important leaf vegetable crop rich in apigenin in the Apiaceae family显示文摘Celery(Apium graveolens L.)is a vegetable crop in the Apiaceae family that is widely cultivated and consumed because it contains necessary nutrients and multiple biologically active ingredients,such as apigenin and terpenoids.Here,we report the genome sequence of celery based on the use of HiSeq 2000 sequencing technology to obtain 600.8 Gb of data,achieving~189-fold genome coverage,from 68 sequencing libraries with different insert sizes ranging from 180 bp to 10 kb in length.The assembled genome has a total sequence length of 2.21 Gb and consists of 34,277 predicted genes.Repetitive DNA sequences represent 68.88%of the genome sequences,and LTR retrotransposons are the main components of the repetitive sequences.Evolutionary analysis showed that a recent whole-genome duplication event may have occurred in celery,which could have contributed to its large genome size.The genome sequence of celery allowed us to identify agronomically important genes involved in disease resistance,flavonoid biosynthesis,terpenoid metabolism,and other important cellular processes.The comparative analysis of apigenin biosynthesis genes among species might explain the high apigenin content of celery.The whole-genome sequences of celery have been deposited at CeleryDB(http://apiaceae.njau.edu.cn/celerydb).The availability of the celery genome data advances our knowledge of the genetic evolution of celery and will contribute to further biological research and breeding in celery as well as other Apiaceae plants. | Meng-Yao Li Kai Feng Xi-Lin Hou Qian Jiang Zhi-Sheng Xu Guang-Long Wang Jie-Xia Liu Feng Wang Ai-Sheng Xiong | 2020 | Horticulture Research2020，7，1： | 16 |
| 3 | Femtosecond Laser Precision Engineering: From Micron, Submicron, to Nanoscale显示文摘As a noncontact strategy with flexible tools and high efficiency,laser precision engineering is a significant advanced processing way for high-quality micro-/nanostructure fabrication,especially to achieve novel functional photoelectric structures and devices.For the microscale creation,several femtosecond laser fabrication methods,including multiphoton absorption,laserinduced plasma-assisted ablation,and incubation effect have been developed.Meanwhile,the femtosecond laser can be combined with microlens arrays and interference lithography techniques to achieve the structures in submicron scales.Down to nanoscale feature sizes,advanced processing strategies,such as near-field scanning optical microscope,atomic force microscope,and microsphere,are applied in femtosecond laser processing and the minimum nanostructure creation has been pushed down to~25 nm due to near-field effect.The most fascinating femtosecond laser precision engineering is the possibility of large-area,high-throughput,and far-field nanofabrication.In combination with special strategies,including dual femtosecond laser beam irradiation,~15 nm nanostructuring can be achieved directly on silicon surfaces in far field and in ambient air.The challenges and perspectives in the femtosecond laser precision engineering are also discussed. | Zhenyuan Lin Minghui Hong | 2021 | Ultrafast Science2021，，1： | 13 |
| 4 | Confined van der Waals Epitaxial Growth of Two-Dimensional Large Single-Crystal In_(2)Se_(3) for Flexible Broadband Photodetectors显示文摘The controllable growth of two-dimensional(2D)semiconductors with large domain sizes and high quality is much needed in order to reduce the detrimental efect of grain boundaries on device performance but has proven to be challenging.Here,we analyze the precursor concentration on the substrate surface which signifcantly infuences nucleation density in a vapor deposition growth process and design a confned micro-reactor to grow 2D In_(2)Se_(3) with large domain sizes and high quality.Te uniqueness of this confned micro-reactor is that its size is∼102-103 times smaller than that of a conventional reactor.Such a remarkably small reactor causes a very low precursor concentration on the substrate surface,which reduces nucleation density and leads to the growth of 2D In_(2)Se_(3) grains with sizes larger than 200�m.Our experimental results show large domain sizes of the 2D In_(2)Se_(3) with high crystallinity.Te fexible broadband photodetectors based on the as-grown In_(2)Se_(3) show rise and decay times of 140 ms and 25 ms,efcient response(5.6 A/W),excellent detectivity(7×10^(10) Jones),high external quantum efciency(251%),good fexibility,and high stability.Tis study,in principle,provides an efective strategy for the controllable growth of high quality 2D materials with few grain boundaries. | Lei Tang Changjiu Teng Yuting Luo Usman Khan Haiyang Pan Zhengyang Cai Yue Zhao Bilu Liu Hui-Ming Cheng | 2019 | Research2019，，1： | 7 |
| 5 | Kinetic and thermodynamic studies on partitioning of polychlorinated biphenyls (PCBs) between aqueous solution and modeled individual soil particle grain sizes显示文摘The significance of soil mineral properties and secondary environmental conditions such as pH, temperature, ionic strength and time in the partitioning of eight selected polychlorinated biphenyl(PCB) congeners between aqueous solution and soil particles with different grain sizes was studied. The mineral properties of a model soil sample were determined, and Brunauer–Emmett–Teller(BET) adsorption–desorption isotherms were employed to observe the surface characteristics of the individual modeled soil particles.Batch adsorption experiments were conducted to determine the sorption of PCBs onto soil particles of different sizes. The results revealed that the sorption of PCB congeners onto the soil was dependent on the amount of soil organic matter, surface area, and pore size distribution of the various individual soil particles. Low pH favored the sorption of PCBs,with maximum sorption occurring between pH 6.5 and 7.5 with an equilibration period of 8 hr.Changes in the ionic strength were found to be less significant. Low temperature favored the sorption of PCBs onto the soil compared to high temperatures. Thermodynamic studies showed that the partition coefficient(K_d) decreased with increasing temperature, and negative and low values of ΔH° indicated an exothermic physisorption process. The data generated is critical and will help in further understanding remediation and cleanup strategies for polluted water. | Gbadebo Clement Adeyinka Brenda Moodley | 2019 | Journal of Environmental Sciences2019，31，2： | 6 |

| 9 | Responsive Inverse Opal Scaffolds with Biomimetic Enrichment Capability for Cell Culture显示文摘Three-dimensional(3D)porous scaffolds have a demonstrated value for tissue engineering and regenerative medicine.Inspired by the predation processes of marine predators in nature,we present new photocontrolled shrinkable inverse opal graphene oxide(GO)hydrogel scaffolds for cell enrichment and 3D culture.The scaffolds with adjustable pore sizes and morphologies were created using a GO and N-isopropylacrylamide dispersed solution as a continuous phase of microfluidic emulsions for polymerizing and replicating.Because of the interconnected porous structures and the remotely controllable volume responsiveness of the scaffolds,the suspended cells could be enriched into the inner spaces of the scaffolds through predator-like swallowing and discharging processes.Hepatocyte cells concentrated in the scaffold pores could form denser 3D spheroids more quickly via the controlled compression force caused by the shrinking of the dynamic scaffolds.More importantly,with a program of scaffold enrichment with different cells,an unprecedented 3D multilayer coculture system of endothelial-cellencapsulated hepatocytes and fibroblasts could be generated for applications such as liver-on-a-chip and bioartificial liver.It was demonstrated that the resultant multicellular system offered significant improvements in hepatic functions,such as albumin secretion,urea synthesis,and cytochrome P450 expression.These features of our scaffolds make them highly promising for the biomimetic construction of various physiological and pathophysiological 3D tissue models,which could be used for understanding tissue level biology and in vitro drug testing applications. | Changmin Shao Yuxiao Liu Junjie Chi Jie Wang Ze Zhao Yuanjin Zhao | 2019 | Research2019，，1： | 4 |
| 10 | A tailored,electronic textile conformable suit for large-scale spatiotemporal physiological sensing in vivo显示文摘The rapid advancement of electronic devices and fabrication technologies has further promoted the field of wearables and smart textiles.However,most of the current efforts in textile electronics focus on a single modality and cover a small area.Here,we have developed a tailored,electronic textile conformable suit(E-TeCS)to perform large-scale,multimodal physiological(temperature,heart rate,and respiration)sensing in vivo.This platform can be customized for various forms,sizes and functions using standard,accessible and high-throughput textile manufacturing and garment patterning techniques.Similar to a compression shirt,the soft and stretchable nature of the tailored E-TeCS allows intimate contact between electronics and the skin with a pressure value of around~25 mmHg,allowing for physical comfort and improved precision of sensor readings on skin.The E-TeCS can detect skin temperature with an accuracy of 0.1℃ and a precision of 0.01℃,as well as heart rate and respiration with a precision of 0.0012 m/s^(2) through mechano-acoustic inertial sensing.The knit textile electronics can be stretched up to 30%under 1000 cycles of stretching without significant degradation in mechanical and electrical performance.Experimental and theoretical investigations are conducted for each sensor modality along with performing the robustness of sensor-interconnects,washability,and breathability of the suit.Collective results suggest that our E-TeCS can simultaneously and wirelessly monitor 30 skin temperature nodes across the human body over an area of 1500 cm2,during seismocardiac events and respiration,as well as physical activity through inertial dynamics. | Irmandy Wicaksono Carson ITucker Tao Sun Cesar A.Guerrero Clare Liu Wesley M.Woo Eric J.Pence Canan Dagdeviren | 2020 | npj Flexible Electronics2020，4，1： | 4 |
| 11 | Response of grain size of Quaternary gravels to climate and tectonics in the northern Tibetan Plateau显示文摘The widely distributed thick gravel deposits along the rim of the Tibetan Plateau have been long thought to be the product of rapid tectonic uplift of the plateau. However, this has been challenged by recent works that suggest these thick gravels may be the result of climate change. In this paper we carried out a detailed field measurement of gravel grain sizes from the Jiuquan and Gobi Gravel Beds in the top of the Laojunmiao section in the Jiuxi Basin in the northern margin of Qilian Mts. (northern Tibetan Plateau). The results suggest that the grain sizes of the Jiuquan and Gobi Gravel Beds over the last 0.8 Ma are characterized by nine coarse-fine cycles having strong 100-ka and 41-ka periodicities that correlate well with the loess-paleosol monsoon record and isotopic global climatic record from deep sea sediments as well as by a long trend of coarsening in gravel grain size. The coarse gravel layers were formed during the warm-humid interglaciations while the fine layers correspond to the cold-dry glaciations. Because the paleoclimate in NW China began to get dramatically drier after the mid-Pleistocene, we think the persistent coarsening of gravel grain size was most probably caused by the rapid uplift of the northern Tibetan Plateau, and that the orbital scale cyclic variations in gravel grain size were driven by orbital forcing factors that were superimposed on the tectonically-forced long-term coarsening trend in gravel size. These findings also shed new light on the interaction results of climate and tectonics in relation to the uplift of the Tibetan Plateau. | FU KaiDao FANG XiaoMin GAO JunPing HAN WenXia LI LiLi | 2007 | Science China Earth Sciences2007，50，1： | 3 |
| 12 | A high-quality reference genome of wild Cannabis sativa显示文摘Cannabis sativa is a well-known plant species that has great economic and ecological significance.An incomplete genome of cloned C.sativa was obtained by using SOAPdenovo software in 2011.To further explore the utilization of this plant resource,we generated an updated draft genome sequence for wild-type varieties of C.sativa in China using PacBio single-molecule sequencing and Hi-C technology.Our assembled genome is approximately 808 Mb,with scaffold and contig N50 sizes of 83.00 Mb and 513.57 kb,respectively.Repetitive elements account for 74.75%of the genome.A total of 38,828 protein-coding genes were annotated,98.20%of which were functionally annotated.We provide the first comprehensive de novo genome of wild-type varieties of C.sativa distributed in Tibet,China.Due to long-term growth in the wild environment,these varieties exhibit higher heterozygosity and contain more genetic information.This genetic resource is of great value for future investigations of cannabinoid metabolic pathways and will aid in promoting the commercial production of C.sativa and the effective utilization of cannabinoids.The assembled genome is also a valuable resource for intensively and effectively investigating the C.sativa genome further in the future. | Shan Gao Baishi Wang Shanshan Xie Xiaoyu Xu Jin Zhang Li Pei Yongyi Yu Weifei Yang Ying Zhang | 2020 | Horticulture Research2020，7，1： | 3 |
| 13 | High-Throughput Corn Image Segmentation and Trait Extraction Using Chlorophyll Fluorescence Images显示文摘Plant segmentation and trait extraction for individual organs are two of the key challenges in high-throughput phenotyping(HTP)operations.To address this challenge,the Ag Alumni Seed Phenotyping Facility(AAPF)at Purdue University utilizes chlorophyll fluorescence images(CFIs)to enable consistent and efficient automatic segmentation of plants of different species,age,or color.A series of image analysis routines were also developed to facilitate the quantitative measurements of key corn plant traits.A proof-of-concept experiment was conducted to demonstrate the utility of the extracted traits in assessing drought stress reaction of corn plants.The image analysis routines successfully measured several corn morphological characteristics for different sizes such as plant height,area,top-node height and diameter,number of leaves,leaf area,and angle in relation to the stem.Data from the proof-of-concept experiment showed how corn plants behaved when treated with different water regiments or grown in pot of different sizes.High-throughput image segmentation and analysis basing on a plant’s fluorescence image was proved to be efficient and reliable.Extracted trait on the segmented stem and leaves of a corn plant demonstrated the importance and utility of this kind of trait data in evaluating the performance of corn plant under stress.Data collected from corn plants grown in pots of different volumes showed the importance of using pot of standard size when conducting and reporting plant phenotyping data in a controlled-environment facility. | Augusto Souza Yang Yang | 2021 | Plant Phenomics2021，3，1： | 3 |

| 17 | A mass-customizable dermal patch with discrete colorimetric indicators for personalized sweat rate quantification显示文摘In this paper,we present a disposable,colorimetric,user-friendly and mass-customizable dermal patch for chronological collection and discrete real-time in situ measurement of sweat secretion over a small area of skin.The patch consists of a laminated filter paper patterned into radially arranged channels/fingers with water-activated dyes at their tips.As channels are filled during perspiration,their tips change color once fully saturated,providing easily identifiable levels of water loss which in turn can be mapped to personal dehydration levels.The patch can be manufactured at low cost in a variety of sizes to allow hydration monitoring for individuals participating in activities under different conditions(intensity,temperature,humidity,etc.).Furthermore,we describe an analytical model that enables mass customization of such a flexible wearable system accommodating a broad range of sweat rates and volumes to generate patch designs that are personalized to an individual’s sweat rate,desired time of usage,and the temporal resolution of the required feedback.As a proof-of-concept demonstration,we characterized laser-fabricated patches that cover(7 cm×5 cm)area of skin having various wicking materials,thicknesses(180–540μm),and pore sizes(3–11μm).Tests were conducted at various flow rates simulating different sweating intensities in the range of 1.5–15 mg/cm^(2)/min.Experimental results for the case of a half-marathon runner targeting 90 min of usage and sweating at a rate of 1.5 mg/cm2/min indicated measurement accuracy of 98.3%when the patch is completely filled. | Vaibhav Jain Manuel Ochoa Hongjie Jiang Rahim Rahimi Babak Ziaie | 2019 | Microsystems & Nanoengineering2019，5，1： | 2 |
| 18 | CONCURRENT SORPTION OF HEAVY METAL POLLUTANTS OF SEDIMENT OF DIFFERENT GRAIN SIZES显示文摘Generally, sediment in natural rivers is non-uniform, and sorption capacities of different grain sizes vary greatly. In order to quantitatively describe sorption of heavy metal pollutant by sediment in natural rivers, the concurrent sorption by sediment of different grain sizes should be studied. By combining systematic laboratory experiments and theoretical analysis the concurrent equilibrium sorption model and the concurrent sorption dynamic model by sediment of different grain sizes have been set up. Both of them indicate that there is no competition or interference among different grain sizes, its sorption content of unit weight of sediment is the sum of the sorption contents of each grain sizes , and the content of each grain size in non-uniform sediment. Furthermore, formulas for determining characteristic parameters ( b and k) in the Langmuir sorption isotherm for non-uniform sediment are deduced as follows:These can be used as a tool for predicting the sorption content of non-uniform | Huang Sui-liangState Key Joint Laboratory of Environmental Simulation and Pollution Control, Laboratoryof Water Environment Simulation,Beijing Normal University, Beijing 100875, P.
