Color Space Transformation-Based Algorithm for Evaluation of Thermochromic Behavior of Cholesteric Liquid Crystals Using Polarized Light Microscopy

Preparation of Solid Superacid SO42-/ZnO-TiO2 and Its Action on Synthesis of Dimethyl Carbonate from Urea and Methanol

SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett indicator. The catalyst showed strong acidity(H0 ≦-16.0). The optimum conditions are found that th...

Synthesis and Characterization of Four Random copolymers Containing Fluorene as Electron Donors and Benzotriazole, Benzothiadiazole, Pyrido[3,4-b]pyrazine as Electron Acceptors

Four copolymers, poly(fluorene-pyrido[3,4-b]pyrazine) (PFPP), poly(benzotriazole-fluorene-pyrido[3,4-b]pyrazine) (PBTFPP), poly(benzotriazole-fluorene-benzothiadiazole) (PBTFBD), poly(benzothiadiazole-fluorene-benzothiadiazole) (PBDFBD)were...

The Application of Electrospun Titania Nanofibers in Dye-sensitized Solar Cells

Titania nanofibers were fabricated using the industrial NanospiderTM technology. The preparative protocol was optimized by screening various precursor materials to get pure anatase nanofibers. Composite films were prepared by mixing a comme...

Advances and Prospects of China's Premium Deepwater Drilling and Production Equipment

China is now witnessing vigorous offshore exploration and development， corresponding to an increasing demand for localized offshore equipment. To achieve the goal of high-quality development of premium offshore drilling and production equip...

Leaching and recycling of NdFeB permanent magnets using ionic non-toxic hydrotropes instead of extractants

We show hereby that recycling of NdFeB permanent magnets by selective leaching and precipitation is possible, using an electrolyte as hydrotrope, thus avoiding the need of any specific extractant molecules. We analyse the yield of the extra...

Development of a Viscosity Measuring Device for Low Boiling Point Refrigerant Mixtures

According to the need for viscosity measurement of refrigerant mixtures, a new rotatable capillary viscometer is developed and designed. It is adequate for the viscosity investigation of the low boiling point liquid mixtures. A rotatable ca...

The Effect of Time on the Activation of Bayah Natural Zeolite for Application of Palm Oil Shell Pyrolysis

Oil palm shell (OPS) constitutes 60% of the waste generated during the processing of palm oil. However, OPS can potentially be converted into energy and chemicals through pyrolysis. The purpose of this study is to determine and analyse the ...

Debunking the Myths of Vision and Mission Statements: A Content Analysis of FT Ranked Top 100 Business Schools

The purpose of this paper is to answer seven famous myths about vision and mission statements by analysing the vision and mission statements of FT Ranked Top 100 Business Schools in the world. First myth states that all business schools hav...

Chemical composition, antioxidant and antimicrobial potential of essential oils from different parts of Daphne mucronata Royle

Abstract This research work was executed to determine chemical composition, anti-oxidant and anti-microbial potential of the essential oils extracted from the leaves and stem of Daphne mucronata Royle. From leaves and stem oils fifty-one di...

Integrative omics analysis on phytohormones involved in oil palm seed germination

Abstract Background Heat treatment is widely used to break dormancy for seed germination and phytohormones could be deeply involved. However, effect of heat treatment on phytohormone related genes/proteins/metabolites and possible relations...

A large deletion conferring pale green leaves of maize

Abstract Background The structural basis of chloroplast and the regulation of chloroplast biogenesis remain largely unknown in maize. Gene mutations in these pathways have been linked to the abnormal leaf color phenotype observed in some mu...

Analysis of taxonomic distinctness and priority conservation areas as a basis for heritage enhancement of floristic diversity: the case of the ‘hotspot’ of the islands of Numidia (North-eastern Algeria)

The identification of priority conservation areas (PCA) plays an important role in biodiversity conservation, but uncertainties create challenges for conservation planning. The objective was to test a method based on 'taxonomic distinctness...

Biosynthesis of rare 20(R)-protopanaxadiol/protopanaxatriol type ginsenosides through Escherichia coli engineered with uridine diphosphate glycosyltransferase genes

Background: Ginsenosides are known as the principal pharmacological active constituents in Panax medicinal plants such as Asian ginseng, American ginseng, and Notoginseng. Some ginsenosides, especially the 20(R) isomers, are found in trace ...

Deciphering an AgRP-serotoninergic neural circuit in distinct control of energy metabolism from feeding

Neuronal signaling has an important role in the regulation of energy expenditure and body weight, however, the underlying mechanisms are incompletely understood. Here, the authors report a AgRP-MC4R-serotonin expressing neuronal circuit tha...

The molecular crosstalk between RECQ helicases and associated proteins in human genetic disorders

RECQ helicases involve a family of DNA unwinding enzymes, namely, RECQ1, Bloom syndrome protein, Werner syndrome protein, RECQL4, and RECQ5. These proteins interact with various proteins to form complexes and carry out a range of physiologi...

Wilms Tumor 1b defines a wound-specific sheath cell subpopulation associated with notochord repair

Regenerative therapy for degenerative spine disorders requires the identification of cells that can slow down and possibly reverse degenerative processes. Here, we identify an unanticipated wound-specific notochord sheath cell subpopulation...

Brain‐Penetrating and Disease Site‐Targeting Manganese Dioxide‐Polymer‐Lipid Hybrid Nanoparticles Remodel Microenvironment of Alzheimer's Disease by Regulating Multiple Pathological Pathways

Abstract Finding effective disease‐modifying treatment for Alzheimer's disease remains challenging due to an array of factors contributing to the loss of neural function. The current study demonstrates a new strategy, using multitargeted bi...
