“ALL FREE” — a novel design concept of applying partial oxidation process to vehicle

Ling LIN, Wenshuang LIN, Qingbiao LI, Yao ZHOU,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 2, Pages 207-212 doi: 10.1007/s11705-009-0240-3

Abstract: global motor vehicle population, the transportation sector has taken up a growing proportion among allsolutions of the carbon dioxide-oriented problem in transportation, this paper proposes the “ALLFREE” concept that applies partial oxidation process instead of the conventional complete oxidationoxidized into corresponding chemical products, which, as a result, enable the process to be theoretically freeFREE” concept.

Yellow fever and Hajj: with all eyes on Zika, a familiar flavivirus remains a threat

Qanta A. Ahmed,Ziad A. Memish

Frontiers of Medicine 2016, Volume 10, Issue 4, Pages 527-530 doi: 10.1007/s11684-016-0487-2

Abstract:

Hajj is among the world’s largest mass gatherings, drawing between 2 and 3.5 million Muslims from 183 nations annually to perform pilgrimage in Mecca, Saudi Arabia. Infectious disease outbreaks can be imported both into the Hajj population and exported internationally by returning pilgrims. The domestic Saudi population can also be at risk of outbreaks traveling amid this mass migration. With yellow fever reported for the first time in China following the infection of expatriate Chinese workers in Angola and a full blown outbreak underway in wider West Africa, the prospect of yellow fever outbreaks in Asia threatens to impact Saudi Arabia, both during and beyond the Hajj season. With global focus trained on Zika, the rising threat of yellow fever cannot be overlooked. Strategies to mitigate risk to Saudi Arabia and the global population are thereby suggested.

Decontamination of Cr(VI) facilitated formation of persistent free radicals on rice husk derived biochar

Kaikai Zhang, Peng Sun, Yanrong Zhang

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 2, doi: 10.1007/s11783-019-1106-7

Abstract:

PFRs were produced on biochar during Cr(VI) decontamination.

PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI).

Appearance of excessive oxidant led to the consumption of PFRs on biochar.

Biochar charred at high temperature possessed great performance to Cr(VI) removal.
