Abstract null null Drought is a complicated and costly natural hazard and identification of critical drought factors is critical for modeling and forecasting of droughts and hence development of drought mitigation measures (the Standardized Precipitation-Evapotranspiration Index) in both space and time. Here we quantified relationships between drought and 23 drought factors using remote sensing data during the period of 2002–2016. Based on the Gradient Boosting Algorithm (GBM), we found that pre...

Abstract The lithium (Li) metal anode is an integral component in an emerging high-energy-density rechargeable battery. A composite Li anode with a three-dimensional (3D) host exhibits unique advantages in suppressing Li dendrites and maintaining dimensional stability. However, the fundamental understanding and regulation of solid electrolyte interphase (SEI), which directly dictates the behavior of Li plating/stripping, are rarely researched in composite Li metal anodes. Herein, the interaction...

Abstract null null Flexible and wearable sensors have recently found wide applications in health monitoring and human-machine interaction. Desirable features in wearable sensors are high sensitivity and multi-targets detection capability in non-invasive manners. The sensitivity and multi-analyte detection capabilities are a function of the sensing material and sensor structures. Herein, we utilize a single-layer microgels structure integrated into a wearable capacitive sensor to realize both hig...

Abstract null null Bi2Te3-based compounds are well-known commercial thermoelectric materials near room temperature. However, the strong intrinsic excitations above 400 K severely deteriorate the ZT values and limit the applications of thermoelectric power generation. Here, we choose divalent Pb as an acceptor impurity to improve the thermoelectric performance of p-type Bi0.4Sb1.6Te3 sintered materials at higher temperature. Tiny Pb doping not only obviously suppresses the bipolar effect by incre...

Abstract null null Double network elastomer is a class of molecular composites consisting of a brittle filler network and a ductile matrix network. Upon deformation, progressive scission of the filler network dissipates strain energy while the matrix network resists the micro defect propagation, thus enhancing both stiffness and toughness of the composites. Over the past few years, several types of constitutive models have been developed to capture the nonlinear stress-strain relation of double ...

Abstract null null Tailoring the Ti coordination states in titanosilicate zeolites to simultaneously improve feedstock conversion and maximize the target product selectivity remains a challenge in the pursuit of high-performance catalysts for selective oxidation reactions. Herein, we provide a facile strategy to synthesize hierarchical anatase-free TS-1 (MFI-type) zeolites with tetrahedrally coordinated (TiO4) and octahedrally coordinated Ti species (TiO6). The TiO4 species provide high epoxide ...
Abstract null null Laser shock peening (LSP) plays an important role in simultaneously strengthening and toughening materials for many engineering applications, such as key structures of aircraft and ship. This work focused on the application of temporally shaped femtosecond (fs) laser in shock peening 304 stainless steel. In our experiment, a single-fs laser pulse was divided by Michelson interferometer to generate two subpulses with a time delay ranging from 5 to 50 picoseconds (ps), and then ...

Abstract null null Terrestrial lipid biomarkers are one of the key tracers in the studies of atmospheric aerosols. Here, we investigated such organic compounds in marine aerosols collected at Chichijima Island, the western North Pacific for two 4-year periods: 1990–1993 and 2006–2009. A homologous series of lipid biomarkers including C18–C37 n-alkanes, C9–C34 fatty acids, and C14–C35 fatty alcohols were determined by gas chromatography/mass spectrometry (GC/MS). The atmospheric levels of these t...

Abstract null null This study focused on radiolarian diversity in the deep-sea sediments of the East Indian Ocean (EIO) to demonstrate their potential as a paleoceanogrpahic proxy. Radiolarians are in general abundant in deep-sea sediment of the EIO. However, around Sri Lanka, their abundances decrease potentially because of terrigenous matter inputs. The significantly high abundance of radiolarians in the northern Ninety-East Ridge (NER) area may indicate high levels of productivity in the over...

Abstract null null Climate change caused by the increasing emission of CO2 to the atmosphere has become a global concern. To ameliorate this issue, converting CO2 into valuable chemicals is highly desirable, enabling a sustainable low-carbon future. To this end, developing efficient catalytic systems for CO2 conversion has sparked intense interests from both academia and industry. Taking advantage of their highly porous structures and unique properties, metal−organic frameworks (MOFs) have shown...
