Analogy between periodic patterns in thin smectic liquid crystal films and the intermediate state of superconductors
(Natl Acad Sciences, 2020)
Spontaneous breaking of symmetry in liquid crystal (LC) films often reveals itself as a microscopic pattern of molecular align-ment. In a smectic-A LC, the emergence of positional order at the transition from the nematic ...
Prolific pioneers and reserved settlers. Changes in the life-history of the western tubenose goby (Proterorhinus semilunaris) at different invasion stages
(Elsevier B.V., 2021)
The western tubenose goby is one of the most wide-spread invasive fish species in European freshwaters, though information of its life-history in relation to its invasion success is limited. We compared the reproductive ...
Mesenchymal Stem Cells Combined With IFN gamma Induce Apoptosis of Breast Cancer Cells Partially Through TRAIL
(Int Inst Anticancer Research, 2020)
Background: Mesenchymal stem cells (MSCs) have gained remarkable attention because of their ability to dualistically regulate tumor growth. The main objective of this study was to evaluate the apoptotic effects of human ...
Onosma pulchra: Phytochemical composition, antioxidant, skin-whitening and anti-diabetic activity
(Elsevier, 2020)
Researchers have discovered in recent years that some Onosma species have interesting biological/pharmacological activities. This study was conducted to investigate the antioxidant, tyrosinase and alpha-amylase inhibitor ...
Dimensional stabilization of wood treated with furfuryl alcohol catalysed by borates
(Springer, 2004)
Furfuryl alcohol has a sufficiently small molecular size, which allows impregnation into wood and can be polymerized in the cell walls. Polymerization can be accomplished using a catalyst, heat or penetrating radiation. ...
Accelerated weathering performance of Scots pine preimpregnated with copper-based chemicals before varnish coating Part:1 coated with cellulosic and polyurethane varnishes
(Wiley, 2020)
This study aimed to determine the effect of accelerated weathering on gloss, surface hardness and colour changes of Scots pine (Pinus sylvestris L.). Test samples were impregnated with Adolit KD-5, Wolmanit CX-8 and Celcure ...
Selenium and mercury balance in sea bream obtained from different living environments in Turkey: a risk assessment for the consumer health
(Springer, 2021)
The selenium health benefit value (Se-HBV) is the criterion developed for revealing nutritional values or the risks related to mercury (Hg) toxicity which can emerge in relation to consumption of fish. In this study, the ...
Preoperative Mild Pericardial Effusion Is Associated With Perioperative Complications In Elderly Patients Following Hip Fracture Surgery
(Taylor & Francis Inc, 2020)
Background: The prevalence and prognostic value of mild pericardial effusion (MPE) has not been examined in patients undergoing non-cardiac surgery. Our study aimed to assess the frequency and prognostic value of MPE in ...
Rhodium(0), Ruthenium(0) and Palladium(0) nanoparticles supported on carbon-coated iron: Magnetically isolable and reusable catalysts for hydrolytic dehydrogenation of ammonia borane
(Elsevier Ltd, 2020)
We report the synthesis of magnetically isolable ruthenium(0), rhodium(0), and palladium(0) nanoparticles, supported on carbon-coated magnetic iron particles, and their employment as catalysts in hydrolysis of ammonia ...
Efficient photochemical vapor generation of bismuth using a coiled Teflon reactor: Effect of metal sensitizers and analytical performance with flame-in-gas-shield atomizer and atomic fluorescence spectrometry
(Elsevier Inc., 2021)
Photochemical vapor generation (PVG) of bismuth was accomplished in a simple flow–injection system with a standard Hg low-pressure tube lamp and a coiled Teflon reactor. The influence of a reaction medium flow rate ...
