We describe a facile and flexible technique for fabricating double-shelled hybrid hollow microspheres with a controlled void size via in situ miniemulsion polymerization. After monomers polymerize the tetraethoxysilane phase is compressed and restricted as a liquid core leading to the formation of a hollow structure a…
Nano-gas generators were synthesized by encapsulating azo-components into hydrophobic polymer particles. The dispersions of azo-components were subsequently thermally decomposed and could be reacted with either hydrophilic or hydrophobic dyes, which were located in the continuous and dispersed phases, respectively. Bo…
Investigation the Degradation and Devulcanization Reaction of Thermoplastic Vulcanizate using Peroxide Compound was carried out by means of benzoyl peroxide as a devulcanizing agent. The temperature for the recycling condition was gradually increased from 80°C to 190°C because of the half-life of benzoyl peroxide. Fur…
A new method for the crystal growth of alkaline-earth palladate CaPd3O4 was developed. The crystals were synthesized on a voltage-applied electrode in a molten chloride solvent. The maximum length of the crystal was about 1.5 mm. The X-ray diffraction data were refined well by assuming a cubic structure of the space g…
Mechanical properties including fatigue property and microhardness of pre and post fatiguing, have been investigated for four different microstructures (near bi-model, lamellar and basketweave) of TC18 titanium alloys. The correlation of condition fatigue strength and microhardness decreasing among different microstru…
Increasing the synthesis scale is one of the most important issues in nanocrystal synthesis. The main difference between small and large reactors is the thermal transfer rate, which has been reported to have great effects on particle nucleation and growth. According to this viewpoint, the heating rate effects should b…
Magnetic spring utilizing the repulsive force of two permanent magnets is a new device with application in special textile machines. In order to get reliable rules for its design, the effect of geometrical parameters, magnetic properties, material deviations and mechanical inaccuracies should be known, first of all. T…
Mechanothermal (MT) method is one of the methods used for large‐scale production of carbon nanotubes/nanofibers. The different peculiar morphologies of carbon allotropes are introduced with an extraordinary structure for the first time by MT method. In this paper, the influence of milling time and annealing temperatur…
Isocitrate dehydrogenase (IDH) catalyzes the oxidative NAD(P)(+)-dependent decarboxylation of isocitrate into α-ketoglutarate and CO2 and is present in organisms spanning the biological range of temperature. We have solved two crystal structures of the thermophilic Clostridium thermocellum IDH (CtIDH), a native open a…
The Compact Pulsed Hadron Source (CPHS) at Tsinghua University will produce neutrons by bombarding a 13-MeV proton beam from a LINAC system on a beryllium target. One of the purposes of this neutron source is to provide the neutron facilities for characterization of advanced materials with an emphasis on soft matter a…
The EMF method with a solid Cu+-conducting electrolyte of Cu4RbCl3I2 was sued to study the Cu-Tl-Te system in the temperature range of 300–420 K. A diagram of solid-phase equilibriums of this system is constructed, partial molar functions of copper in alloys, standard thermodynamic functions of formation and standard…
CdS nanoribbons with various cross sections offer the opportunity to deeply understand the interaction between optical cavity and spontaneous emission. Herein, long tapered nanoribbons with the cross sections gradually changing were synthesized by a simple physical vapour deposition method. Morphology dependent micro-…
A group of polygonal carbon nanotubes (P-CNTs) have been designed and their mechanical behavior was investigated by classical molecular dynamics simulations. The research aimed at exploring the effects of structure, temperature, and strain rate on the mechanical properties. The results indicate that the Young's modulu…
Stimuli responsive polymeric nanoparticles in regulated drug delivery for cancer Stimuli-responsive drug delivery system is a concept in which a drug is delivered at a suitable rate in response to stimuli. States of diseases may cause an alteration in some parameters of the body (e.g. in tumors) and the onset and offs…
Two energy donor–acceptor self-assembly systems have been constructed by using π–π, lipophilic, and ionic interactions in water. π-stacked N,N′-ditridecylperylenediimide (PDI), which forms nanoribbons, has been dispersed in water in the presence of myristyltrimethylammonium bromide (MTAB) through lipophilic interactio…
Nano-size barium strontium titanate Ba 0.7 Sr 0.3 TiO 3 (BST) maize-bead–like structures were conformally coated on bamboo-like carbon nanotubes (BCNTs) grown on copper substrates. Initially BCNTs were fabricated by hot-filament chemical vapor deposition (HF-CVD) techniques on Cu substrates. Later, BST was deposited o…
Diamond-like carbon (DLC) films are prepared by a bipolar-type plasma-based ion implantation (PBII) technique using toluene and nitrogen gases (N 2 ), and the optical and electrical properties are examined as a function of N 2 flow rate. The N concentration in the films and structural changes are also examined by Ruth…
Mesoporous silica nanoparticles are drawing increasing attention in biomedical applications. In this work, hierarchically nanoporous SBA-1 single-crystal-like nanoparticles, with a size of 50–300 nm, were synthesized using a cationic surfactant and anionic polymer poly(acrylic acid) (PAA) mesomorphous complexes as a t…
In this work, solar micro-thermoelectric generators are designed with a lens concentrating solar radiation onto the membrane of a thermoelectric generator (TEG). By focusing solar radiation, the input heat flux increases; leading to an increase in the temperature gradient across the device. Consequently, a significant…
