1Physico-chemical and mechanical properties of Ti_3SiC_2-based materials elaborated from SiC/Ti by reactive spark plasma sintering显示文摘In this paper, the synthesis of Ti_3 SiC_2 from SiC/Ti powder using reactive spark plasma sintering(R-SPS) in the temperature range of 1300-1400 ℃ is reported. The results show that the purity of Ti_3 SiC_2 is improved up to 75 wt% when the holding time is increased from 10 to 20 min at1400 ℃. The thermodynamic and experimental results indicate that Ti_3 SiC_2 formation takes place via the reaction of a pre-formed TiC phase with the silicides, formed from the eutectic compositions.Detailed analysis of mechanical behaviour indicates that samples with higher percentage of secondary phases exhibit higher microhardness and better resistance compared to the near single phase Ti_3 SiC_2.Faten TURKI Houyem ABDERRAZAK Frédéric SCHOENSTEIN Florent TêTARD Mohieddine ABDELLAOUI Noureddine JOUINI 2019Journal of Advanced Ceramics2019,8,1:2
2Physiological, histopathological and cellular immune effects of Pergularia tomentosa extract on Locusta migratoria nymphs显示文摘The migratory locust Locusta migratoria(Orthoptera,Acrididae)is one of the most important pests due to its extensive and severe damage to crops in large parts of Africa and Asia.Biodegradable and ecologically natural products such as bota nical insecticides are emergi ng can didates for replaceme nt of usually applied chemical pesticides.The crude methanolic extract of Pergularia tomentosa(PME)was investigated for their toxicity and physiological aspects on L.migratoria nymphs.Results showed that treatment of newly emerged fourth and fifth instar nymphs resulted in significant mortality and significant repellent activity with an LC50 value of 0.18 and 0.38%,respectively,after seven days of treatment.The PME toxicity was also dem on strated by histopathological cha nges in the alime ntary canal resulting in con siderable disorganization and severe damage of the caeca and proventriculus structure.The extract induced cellular immune reactions which manifested by a significant decrease in the number of the differential haemocyte counts(prohemocytes and plasmatocytes)and important cell lysis.Data of biochemical analyses showed that the PME reduced the activity of acetylcholinesterase and induced the glutathione S-transferases.The neurotoxic effect was confirmed by the histological alterations in the brain structure,particularly in the neurosecretory cells showing typical signs of cell necrosis.Meriam Miladi Khemais Abdellaoui Amel Ben Hamouda Iteb Boughattas Mouna Mhafdhi Fatma Acheuk Monia Ben Halima-Kamel 2019Journal of Integrative Agriculture2019,18,12:2
