In this work, an economical modifier silane agent—KH550—was used for surface treatment of basalt fiber. Then, a biodegradable poly(butylene succinate) (PBS)/modified basalt fiber (MBF) biocomposite was successfully developed. The effects of silane treatment and fiber mass content on crystalline structure, isothermal crystallization process and mechanical performance of composites were evaluated...

Although the stoichiometry of bulk lead sulfide (PbS) is exactly 1:1, that of quantum dots (QDs) can be considerably different from this crystalline limit. Employing first-principles calculations, we show that the impact of PbS QD stoichiometry on the electronic structure can be enormous, suggesting that control over the overall stoichiometry in the QD will play a critical role for improving th...

The kinetics of the isothermal crystallization process from the melt of pure poly(butylene succinate)-co-(butylene carbonate) (PBS-co-BC) and its blends with cellulose acetate butylate (CAB) (10–30 wt%) was studied by differential scanning calorimetry (DSC) and the well-known Avrami equation. In the blends, the overall crystallization rate of PBS-co-BC became slower with increasing CAB content....

  TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...

Aim: Epistaxis may be a symptom of an inherited bleeding disease.. We aimed to analyze approved pediatric score (PBS) as screening test for von Willebrand Disease (VWD) in children with epistaxis 
 Material and Method: retrospectively reviewed the medical records patients, who applied Pediatric Hematology Department complaint between January 2018 December 2019.
 Results: One hundred s...

Systems of two immiscible liquid phases—aqueous phase (i.e., distilled water (dH2O) or phosphate-buffered saline (PBS)) and perfluorochemical perfluorodecalin (PFD))—were subjected to wave-assisted agitation, i.e., oscillatory rocked, in a disposable bag-like container ReadyToProcess WAVETM25 bioreactor, recognize oxygen transfer effects effectivity the surface aeration. According DoE methodolo...

Semiconductor nanocrystals are promising for use in cheap and highly efficient solar cells. A high efficiency can be achieved by carrier multiplication (CM), which yields multiple electron-hole pairs for a single absorbed photon. Lead chalcogenide nanocrystals are of specific interest, since their band gap can be tuned to be optimal to exploit CM in solar cells. Interestingly, for a given photo...

Due to the significant increase of peer-to-peer (P2P) traffic in the past few years, more attentions are put on designing effective methodologies of monitoring and identifying P2P traffic. In this paper, we propose a novel approach to measure and discover the special characteristics of P2P applications, the periodic behaviors, from the packet traces. We call this the “periodic behavioral spectr...

The local environment of the Pb atom in Pb(x)Sn(1-x)S solid solution was studied by EXAFS technique. The shortest Pb-S bond length in orthorhombic samples was found to be by approximately 0.2 A shorter than in cubic PbS. This indicates that the 6s2 lone pair of Pb is stereochemically active in the SnS host. Strong correlations found in the distribution of metal atoms in the second shell show th...
