Abstract Background With the increasing concerns on energy shortage and carbon emission issues worldwide, sustainable recovery from thermal processes is consistently attracting extensive attention. Nowadays, a significant amount of usable wasted not recovered worldwide every year. Meanwhile, discharging often causes environmental hazards. Significant social ecological impacts will be achieved i...
A novel method of synthesizing and controlling the size of germanium nanocrystals was developed. A tri-layer structure comprising of a thin (~5nm) SiO2 layer grown using rapid thermal oxidation (RTO), followed by a layer of Ge+SiO2 of varying thickness (6 20 nm) deposited using the radio frequency (r.f.) co-sputtering technique and a SiO2 cap layer (50nm) deposited using r.f. sputtering, was in...
*Correspondence: Peer M. Schenk, Algae Biotechnology Laboratory, School of Agriculture and Food Sciences, The University of Queensland, Level 5, John Hines Building, Brisbane, QLD 4072, Australia e-mail: [email protected] Microalgal lipid recovery for biodiesel production is currently considered suboptimal, but pre-treatment of algal biomass, the use of solvent mixtures and the positioning of ...
Effects of matrix cracks and the attendant interface debonding and sliding on both the longitudinal and the transverse thermal diffusivities of a unidirectional Nicalon/MAS composite are investigated. The diffusivity measurements are made in situ during tensile testing using a phase-sensitive photothermal technique. The contribution to the longitudinal thermal resistance from each of the cracks...
در یک برنامه جداسازی و غربالگری باکتریهای مولد بیوسورفکتانت از نمونه های آب شور چاههای مختلف مخزن نفت مسجد سلیمان، باکتریهای بیهوازی اختیاری با تحمل شوری و دمای بالا جداسازی شد براساس معیارهایی نظیر تحمل به شوری و دمای بالا، فعالیت همولیتیک روی نحیط آگار حاوی خون دفیبرینه شده و کاهش کشش سطحی، در نهایت 8 سویه باکتریایی مولد بیوسورفکتانت از بین دیگر سویه ها غربالگری شد هر یک از این سویه ها قادر ب...

We demonstrate that a biphenyl-bridged imidazole dimer exhibits fast photochromism with a thermal recovery time constant of ∼100 ns, which is the fastest thermal back reaction in all reported imidazole dimers. Sub-ps transient absorption spectroscopy reveals that the generation process of the colored species occurs within 1 ps.
