Bioinspired superwetting surfaces for biosensing

Abstract: Inspired by nature, scientists and researchers have studied the wetting behaviors on various creatures and mimicked their structures to fabricate diverse functional superwetting materials. As one kind of emerging application, the bioinspired superwettable surfaces used for biosensing have been aroused wide interests. In this review, we summarized the recent developments of bioinspired superwettable surfaces in the field of biosensing. In the first part, superwettable creatures in nature, namely, superhydrophobic self‐cleaning lotus leaf, high‐adhesion superhydrophobic rose petal, amphiphobic springtail, patterned wetting desert beetles, slippery pitcher plant, were introduced. In sequence, we successively described the special wetting models of superhydrophobicity, superamphiphobicity, responsive wettability, patterned wettability, and slipperiness. Then, biosensing applications based on the respective patterned wettable, superhydrophobic, responsive wettable, and slippery substrates that were combined with the common detection approaches (colorimetry, fluorescence, surface‐enhanced Raman scattering (SERS), electrochemistry) were shown in detailed. At last, an insight of remaining challenges and future development for bioinspired superwetting materials applied in biosensing was provided.

Distribution of Airborne SARS-CoV-2 and possible aerosol transmission in Wuhan hospitals, China

Abstract: SARS-CoV-2 viral RNA was found in 21% of the aerosol (n = 38) and 39% of the mask (n = 23) samples collected from Wuhan hospitals early in 2020 Viable virus was isolated from one surgical mask, but not from any of the viral RNA positive aerosol samples

Water environment vertical distribution comprehensive on-line monitoring buoy and monitoring system

Abstract: The invention relates to a vertical distribution comprehensive on-line monitoring buoy and a monitoring system and belongs to the technical field of environment pollution monitoring The buoy includes a buoy body, an electronic device sealing cabin, a Beidou satellite navigation positioning module, a storage battery pack, a data collector and a 4G router, and a sensor which is arranged on periphery of the buoy body, and a power supply apparatus arranged on the upper part of the buoy body The invention provides the self-moving monitoring buoy which can perform an environment monitoring operation task continuously for long time in a preset waste area range, wherein the buoy can measure water environment parameters and environmental meteorological parameters in different depth The Beidou satellite navigation positioning module and 4G communication network are switched to achieve positioning and communication of the buoy The buoy and the system achieve real-time monitoring, real-time analysis and alarm prediction of monitoring regional environment parameters

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Fast parallel algorithms for short-range molecular dynamics

Abstract: Three parallel algorithms for classical molecular dynamics are presented. The first assigns each processor a fixed subset of atoms; the second assigns each a fixed subset of inter-atomic forces to compute; the third assigns each a fixed spatial region. The algorithms are suitable for molecular dynamics models which can be difficult to parallelize efficiently—those with short-range forces where the neighbors of each atom change rapidly. They can be implemented on any distributed-memory parallel machine which allows for message-passing of data between independently executing processors. The algorithms are tested on a standard Lennard-Jones benchmark problem for system sizes ranging from 500 to 100,000,000 atoms on several parallel supercomputers--the nCUBE 2, Intel iPSC/860 and Paragon, and Cray T3D. Comparing the results to the fastest reported vectorized Cray Y-MP and C90 algorithm shows that the current generation of parallel machines is competitive with conventional vector supercomputers even for small problems. For large problems, the spatial algorithm achieves parallel efficiencies of 90% and a 1840-node Intel Paragon performs up to 165 faster than a single Cray C9O processor. Trade-offs between the three algorithms and guidelines for adapting them to more complex molecular dynamics simulations are also discussed.
