“…aegypti was first documented with natural infection by CHIKV in 2017 in Brazil and the Americas, attributed to the ECSA genotype [5], the same found in the present study. This finding aligns with the widespread prevalence of the ECSA genotype since its introduction in 2014 [45], frequently detected in humans CHIK cases in Brazil [46,47], included those in the state of Minas Gerais [48]. Despite its importance, there are few reports on genomic CHIKV surveillance in mosquitoes from Brazil [6,[12][13][14][49][50][51][52].…”

The Chikungunya virus (CHIKV) presents global health challenges, with Brazil witnessing out-breaks since its introduction in 2014. In 2023, Minas Gerais (MG) experienced a CHIKV outbreak, prompting entomological investigations to identify vectors, viral lineages, and assess insecticide resistance. This study utilized social media platforms and citizen science concept to conduct a comprehensive entomological survey. Following Instagram posts, residents with CHIKV sus-pected cases were able to schedule mosquito aspirations. During the aspirations, 421 mosquitoes (165 Aedes aegypti and 256 Culex quinquefasciatus) were captured from 40 households in Salinas city (MG) and tested for Dengue, Zika and Chikungunya viruses through RT-qPCR. Twelve out 57 pools (10 of Ae. aegypti and 2 of Cx. quinquefasciatus) tested positive for CHIKV RNA. Viral RNA was also detected in the heads of 9 Ae. aegypti individuals (but not in Cx. quinquefasciatus). Genome sequencing revealed that CHIKV belonged to the East-Central-South-Africa (ECSA) genotype. Additionally, genetic analyses revealed high frequencies of kdr alleles, suggesting resistant to pyrethroids insecticides in this Ae. aegypti population. These findings emphasize the urgent need for innovative vector study and control strategies to combat arbovirus transmission, and inter-disciplinary approaches in public health interventions.

“…390 De Souza et al used EXAFS to study the well-known catalytic system [Ni((1,4-bis(2,6diisopropylphenyl)-acenaphtenediimine))Cl 2 ] associated with MAO in the presence of 1-decene. 391 The first coordination sphere presents two carbon and two nitrogen atoms. The low number of carbon atoms measured, compared with the expected cationic intermediate [Ni(α-diimine)(R)(1-decene)] + , is explained by the presence of multiple nickel species, some being unsaturated, like [Ni(α-diimine)(R)] + .…”

“…Spencer et al, as an example, have prepared a series of cationic ethylnickel complexes, stabilized by β-agostic interaction, by addition of HBF 4 to [Ni(P,P)(η 2 -C 2 H 4 )] in which (P,P) = tBu 2 P(CH 2 ) 2 PtBu 2 , tBu 2 P-(CH 2 ) 3 PtBu 2 or o-(tBu 2 PCH 2 ) 2 C 6 H 4 , and demonstrated that an ethylene migratory insertion step occurs during this process. 392 A dicationic nickel(II) complex [Ni(MeCN) 6 ][(BF 4 )] 2 has been reported by de Souza et al as an effective ethylene oligomerization catalyst when associated with AlEt 3 or AlEt 2 Cl, 393 however no further information regarding the nature of the active catalyst involved was reported.…”

Nickel Catalyzed Olefin Oligomerization and Dimerization

Brought to life more than half a century ago and successfully applied for high-value petrochemical intermediates production, nickel-catalyzed olefin oligomerization is still a very dynamic topic, with many fundamental questions to address and industrial challenges to overcome. The unique and versatile reactivity of nickel enables the oligomerization of ethylene, propylene and butenes into a wide range of oligomers that are highly sought-after in numerous fields to be controlled. Interestingly, both homogeneous and heterogeneous nickel catalysts have been scrutinized and employed to do this. This rare specificity encouraged us to interlink them in this review so as to open up opportunities for further catalyst development and innovation. An in-depth understanding of the reaction mechanisms in play is essential to being able to fine-tune the selectivity and achieve efficiency in the rational design of novel catalytic systems. This review thus provides a complete overview of the subject, compiling the main fundamental/industrial milestones and remaining challenges facing homogeneous/heterogeneous approaches as well as emerging catalytic concepts, with a focus on the last 10 years.

“…Green roofs can increase the area of urban green space and alleviate the heat island effect; besides, they also have a regulating effect on the temperature of the building roof and indoor. As the indoor temperature decreases in summer by using green roofs, the frequency and duration of cooling equipment use decrease, which results in the reduction in the energy consumption of air conditioners and electric fans [44,45], this benefit can be calculated as follows:…”

The implementation of grey and green infrastructure is an effective mean to address urban flooding and nonpoint source pollution, but due to the complexity of the process and the diver-sity of benefits, there is a lack of measurement for their comprehensive benefits. Adopting a typ-ical university in Beijing as an example, this paper simulated the multidimensional benefits of the water quantity, water quality, and ecology of grey and green facility renovation by coupling the storm water management model (SWMM) and InfoWorks Integrated Catchment Manage-ment (ICM). Monetization methods and economical means were employed to characterize the comprehensive benefits. The results showed that grey and green infrastructure retrofitting re-duces the number of severe overflow nodes in the study area by 54.35%, the total overflow vol-ume by 22.17%, and the nonpoint source pollution level by approximately 80% under the heavy rain scenario and 60% under the rainstorm scenario. The annual benefits of grey and green infra-structure renovation reached ¥765,600/year, of this amount, ¥83,100/year is from hydrological regulation, ¥454,100/year is from nonpoint source pollution reduction, and ¥228,300/year is from ecological improvement. The benefits of green facilities were higher than those of grey facilities, and the combined benefits were negatively correlated with the rainfall level, with a total bene-fit–cost ratio of 1.19. The results provide methodological and data support for grey and green in-frastructure retrofitting within the context of sponge cities.
