Coordinated control of PM2.5 and O3 is urgently needed in China after implementation of the "Air pollution prevention and control action plan".

Chemosphere, 2020
To improve air quality, China formulated the Air Pollution Prevention and Control Action Plan (APPCAP) in 2013. In the present study, the changes in the concentration of air pollutants after the implementation of APPCAP were investigated based on ...

Poly[(μ4-adamantane-1,3-dicarboxylato-κ5O1:O1':O3,O3':O3')(μ3-adamantane-1,3-dicarboxylato-κ5O1,O1':O3,O3':O3')dimagnesium]: a layered coordination polymer.

Acta crystallographica. Section C, Crystal structure communications, 2012
The title compound, [Mg(2)(C(12)H(14)O(4))(2)](n), is the first example of an s-block metal adamantanedicarboxylate coordination polymer. The asymmetric unit comprises two crystallographically unique Mg(II) centers and two adamantane-1,3-dicarboxylate ligands. The compound is constructed from a combination of chains of corner-sharing magnesium-centered

Giant piezoelectricity of Sm-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals

Science, 2019
Samarium supersensors Piezoelectric materials produce electric charge in response to changes in stress and are thus good sensor materials. One challenge has been growing single-crystal piezoelectrics with uniform properties.

O3

Proceedings of the Twelfth ACM International Symposium on Mobile Ad Hoc Networking and Computing, 2011
Opportunistic routing achieves significant performance gain under lossy wireless links. In this paper, we develop a novel approach that exploits inter-flow network coding in opportunistic routing. A unique feature of our design is that it systematically optimizes end-to-end performance (e.g., total throughput). A key challenge to achieve this goal is a
