Defective Ru-doped α-MnO2 nanorods enabling efficient hydrazine oxidation for e...
Yu, Zhipeng; Si, Chaowei; Sabaté, Ferran; LaGrow, Alec P.; Tai, Zhixin; Diaconescu, Vlad Martin; Simonelli, Laura; Meng, Lijian; Sabater, Maria J.Proton exchange membrane water electrolysis (PEMWE) showes substantial advantages over the conventional alkaline water electrolysis (AWE) for power-to-hydrogen (PtH) conversion, given the faster response and wider dynamic current range of the PEMWE technology. However, PEMWE is currently still expensive due partly to the high voltage needed to operate at high current densities and inevitable usage of precious i...

A data-driven model to quantify the impact of river discharge on tide-river dyn...
Cai, Huayang; Li, Bo; Garel, Erwan; Pan, Haidong; Zhao, Tongtiegang; Liu, Feng; Ma, Yuting; Ou, SuyingUnderstanding the role of river discharge on tide-river dynamics is of essential importance for sustainable water management (flood control, salt intrusion, and navigation) in estuarine environments. It is well known that river discharge impacts fundamental tide-river dynamics, especially in terms of subtidal (residual water levels) and tidal properties (amplitudes and phases for different tidal constituents). ...
Extension of the general unit hydrograph theory for the spread of salinity in e...
Cai, Huayang; Li, Bo; Gu, Junhao; Zhao, Tongtiegang; Garel, ErwanFrom both practical and theoretical perspectives, it is essential to be able to express observed salinity distributions in terms of simplified theoretical models, which enable qualitative assessments to be made in many problems concerning water resource utilization (such as intake of fresh water) in estuaries. In this study, we propose a general and analytical salt intrusion model inspired by Guo's general unit...
Iridium–Iron Diatomic Active Sites for Efficient Bifunctional Oxygen Electrocat...
Yu, Zhipeng; Si, Chaowei; LaGrow, Alec P.; Tai, Zhixin; Caliebe, Wolfgang A.; Tayal, Akhil; Sampaio, Maria J.; Sousa, Juliana P. S.; Amorim, IsildaDiatomic catalysts, particularly those with heteronuclear active sites, have recently attracted considerable attention for their advantages over single-atom catalysts in reactions involving multielectron transfers. Herein, we report bimetallic iridium−iron diatomic catalysts (IrFe−N−C) derived from metal−organic frameworks in a facile wet chemical synthesis followed by postpyrolysis. We use various advanced cha...
Bifunctional atomically dispersed ruthenium electrocatalysts for efficient bipo...
Yu, Zhipeng; Si, Chaowei; Escobar-Bedia, Francisco Javier; LaGrow, Alec P.; Xu, Junyuan; Sabater, Maria J.; Amorim, Isilda; Araujo, AnaAtomically dispersed catalysts (ADCs) have recently drawn considerable interest for use in water electrolysis to produce hydrogen, because they allow for maximal utilization of metal species, particularly the expensive and scarce platinum group metals. Herein, we report the electrocatalytic performance of atomically dispersed ruthenium catalysts (Ru ADCs) with ultralow Ru loading (0.2 wt%). The as-obtained Ru A...
Complex in vitro 3D models of digestive system tumors to advance precision medi...
Song, Sheng-Lei; Li, Bo; Carvalho, M. R.; Wang, H. - J.; Mao, De-Li; Wei, Ji-Tao; Chen, W.; Weng, Zhi-Hui; Chen, Yang-Chao; Deng, Chu-Xia; Reis, R. L.Digestive system cancers account for nearly half of all cancers around the world and have a high mortality rate. Cell culture and animal models represent cornerstones of digestive cancer research. However, their ability to en- able cancer precision medicine is limited. Cell culture models cannot retain the genetic and phenotypic heteroge- neity of tumors and lack tumor microenvironment (TME). Patient-derived xe...
The genome and transcriptome of Japanese flounder provide insights into flatfis...
Shao, Changwei; Bao, Baolong; Xie, Zhiyuan; Chen, Xinye; Li, Bo; Jia, Xiaodong; Yao, Qiulin; Orti, Guillermo; Li, Wenhui; Li, Xihong; Hamre, KristinFlatfish have the most extreme asymmetric body morphology of vertebrates. During metamorphosis, one eye migrates to the contralateral side of the skull, and this migration is accompanied by extensive craniofacial transformations and simultaneous development of lopsided body pigmentation(1-5). The evolution of this developmental and physiological innovation remains enigmatic. Comparative genomics of two flatfish...
