| 1 | Optical properties and cooling performance analyses of single-layer radiative cooling coating with mixture of TiO_(2) particles and SiO_(2) particles显示文摘Radiative cooling can achieve cooling effect without consuming any energy by delivering energy into outer space(3K) through'atmospheric window'(8–13 μm). Conventional radiative cooling coating with multi-layer structure was severely restricted during application due to its complex preparation process and high cost. In this study, a single-layer radiative cooling coating with mixture of TiO_(2) particles and SiO_(2) particles was proposed. The algorithm for calculating the radiative properties of the multi-particle system was developed. Monte Carlo ray-tracing method combined with that algorithm was used to solve the radiative transfer equation(RTE) of the single-layer radiative cooling coating with mixture of TiO_(2) particles and SiO_(2) particles.The effects of particle diameter, volume fraction and coating thickness on radiative cooling performance were analyzed to obtain the best radiative cooling performance. The numerical results indicated that the average reflectivity of the single-layer radiative cooling coating with mixture of TiO_(2) particles and SiO_(2) particles in the solar spectrum can reach 95.6%, while and the average emissivity in the 'atmospheric window' spectrum can reach 94.9% without additional silver-reflectance layer. The average reflectivity in the solar spectrum and average emissivity in the 'atmospheric window' spectrum of the single-layer radiative cooling coating with mixture of TiO_(2) particles and SiO_(2) particles can increase 4.6% and 4.8% compared to the double-layer radiative cooling coating. This numerical research results can provide a theoretical guidance for design and optimization of single-layer radiative cooling coatings containing mixed nanoparticles. | CHENG ZiMing SHUAI Yong GONG DaYang WANG FuQiang LIANG HuaXu LI GuiQiang | 2021 | Science China(Technological Sciences)2021，64，5： | 4 |

| 3 | Tuning crystal orientation and charge transport of quasi-2D perovskites via halogen-substituted benzylammonium for efficient solar cells显示文摘Quasi-two-dimensional(quasi-2D)perovskites with high stability usually suffers from poor device efficiency.Chemical tuning of the spacer cations has been an effective strategy to achieve efficient and stable quasi-2D perovskite solar cells.Here,we demonstrate that 3-halogon-substituted benzylammonium iodide(3X-BAI,X=F,Cl,Br,I)can significantly affect the orientation of low-dimensional perovskites and charge transport from perovskite to hole extraction layer,as well as device performance.With 3Br-BAI,we achieve the highest device efficiency of 13.21%for quasi-2D perovskites with a nominal n=3 average composition.Our work provides a facile approach to regulate vertical crystal orientation and charge transport via tuning the molecular structure of organic spacer toward high performance quasi-2D perovskite solar cells. | Guiqiang Cheng Jian Wang Rong Yang Cheng Li Hao Zhang Nana Wang Renzhi Li Jianpu Wang Wei Huang | 2022 | Journal of Energy Chemistry2022，31，3： | 1 |
| 4 | Evaluation and application of a milk antibody ELISA for assessing the prevalence and incidence of bovine tuberculosis in dairy herds in Hubei Province,China显示文摘Bovine tuberculosis(bTB)is a chronic zoonotic disease that is endemic in China.Current in-vitro tests for bTB are mainly based on blood assays.Collection of samples results in some stress to the sampled cattle and associated economic losses for the herd owner.This study was designed to investigate the relationship between milk and serum antibody tests for bTB in dairy cows using 85 cows with milk and corresponding blood samples.Totally 4,395 milk samples were used to assesse the apparent(test)prevalence and incidence of bTB using the milk antibody ELISA.The association between levels of bTB milk antibody and milk quality was also evaluated.Milk and serum antibody tests showed a good correlation with a 87.5%(95%CI:61.7%,98.4)positive agreement and 98.7%(95%CI:95.4,99.8)negative agreement.The animal level lactoprevalence ranged from 0.3%(95%CI:0,1.2)to 33.3%(95%CI:26.6,40.6)in different farms and the incidence rate ranged from 0 head/cow-month(95%CI:0,0.02)to 0.04 head/cow-month(95%CI:0.02,0.07).Twenty percent of sampled farms met the criteria for bTB control in China.The prevalence on large-scale farms was lower(p<0.001)than on small farms.The bTB milk antibody levels had a negative correlation with milk yield and a positive correlation with somatic cell count(SCC),milk protein percentage(MPP)and percentage of total solids(TS).According to this research,milk ELISA could be used as a supplement of blood samples to assist in the surveillance for bTB and for alerting control and eradication of bTB. | Yingyu Chen Shuang Cheng Yu Wang Guiqiang Wang Xijuan Wu Ian D.Robertson Aizhen Guo | 2023 | Animal Diseases2023，3，2： | 0 |
| 5 | Interfacial self-transportation via controlled wettability transition for directed self-assembly显示文摘Wettability transition is a significant responsive mechanism which is widely applied to construct smart materials and systems.The broad-spectrum responsiveness of the wettability transition makes it a promising way to expand innovative applications.Here,we develop a track-guided self-transportation system mediated by sequential wettability transition accompanied with capillary transportation.Alkaline fuel is loaded into polydimethylsiloxane(PDMS)cuboid to trigger the wettability transition of distributed superhydrophobic tracks laid in shallow water.After the wettability transition,the induced capillary force can propel the repetitive track-to-track transportation of PDMS.Importantly,the spacing between adjacent tracks is rationally designed based on multiple factors including threshold of wettability transition,diffusion kinetics and capillary interaction.Furthermore,the track-guided transportation system is applied to realize directed self-assembly of multiple PDMS building blocks for designated configuration,which increases the complexity and intelligence of self-assembly systems. | Pan Tian Minghui Tan Guiqiang Zhu Dan Wang Guoxin Lu Mengjiao Cheng | 2023 | Chinese Chemical Letters2023，34，12： | 0 |
