Mechanical tissue fractionation can be achieved using successive, high-intensity ultrasound pulses in a process termed histotripsy. Histotripsy has many potential clinical applications where noninvasive tissue removal is desired. The primary mechanism for histotripsy is believed to be cavitation. Using fast-gated imag…
This paper reviews the developments of essential elastic fibers. The elastic fibers include extensible polymer fibers with low or high elasticity and reversibility which consists of the polyurethane elastic fiber, polyester‐ether elastic fiber, polyester elastic fiber, olefin based elastic fiber like XLA, hard elastic…
A single phenomenological expression is proposed to describe thermal transport in a wide variety of nanoscale devices. Size and frequency dependence is studied for some nanosystems from the diffusive to the ballistic regimes. In a single expression we obtain the effective thermal conductivity of cross-plane thin layer…
High quality CdSe quantum dots are synthesized through a room temperature injection technique by using CdAc2 and Na2SeSO3 as precursors. In this synthesis approach, small CdSe clusters are formed after the injection at room temperature. Thereafter, CdSe quantum dots with emissions from the green to the red region can…
OBJECTIVE: Clinical proof of concept for polymer conjugates has already been achieved over the last 30 years, with a family of polymer-protein conjugates reaching the market and an exponentially growing list of polymer-drug conjugates currently in clinical trials. However, many challenges and opportunities still lie a…
The solubility of l- (+)-ascorbic acid in water, ethanol, methanol, propan-2-ol, acetone, acetonitrile, ethyl acetate, and tetrahydrofuran was measured by a gravimetrical method from (293 to 323) K, and the solubility data were correlated against temperature. The solubility of l- (+)-ascorbic acid in water and methano…
In recent years, there has been steady progress in developing new polymers and functional polymer fibers. The objectives of this issue are to provide readers an overview of significant advances for the production of high performance fibers such as Kevlar, PBO, Spectra and Dyneema fibers and to describe new super stron…

The addition of diazonium salts to single-walled carbon nanotubes (SWCNTs) in aqueous surfactant suspensions quenches the intrinsic near-infrared fluorescence of semiconducting SWCNTs through sidewall chemical reactions. Spectrally resolved fluorescence spectroscopy of mixed SWCNT samples has been used to measure stru…
In this paper, we describe an easy-to-use method to measure the thermal conductivity of thin films based on an electrical heating/sensing mechanism and a steady-state technique. The method used relative commonly used instruments, and without any signal processing circuit, is easy to be used in such thin-film thermal c…
Permeability spectra of NiZn ferrite with different microstructures had been resolved into contributions of domain wall resonance and spin rotation relaxation. The fitting results of permeability dispersion revealed the relationships among domain wall resonance, spin rotation relaxation mechanisms, and microstructures…
The pressure and temperature dependence of the lowest excitation energy of PbSe (Pb 68 Se 68, d = 2.0 nm) and CdSe (Cd 33 Se 33, d = 1.6 nm) quantum dots (QDs) were investigated by ab initio density functional theory and molecular dynamics simulation. Additionally, pure-dephasing/decoherence induced by the electron–ph…
We investigated the correlation between the thickness of the ZnS shell of CdSe-ZnS quantum dots (QDs), the stability of the particles, and the fluorescence quantum yield. As a measure for stability, a new shell quality test was developed. This test is based on the reaction of the QDs with photochemically formed thioph…
As the need for targeting luminescent biolabels increases, for mapping selected analytes, imaging of cells and organs, and tracking in cellulo processes, lanthanide bimetallic helicates are emerging as versatile bioprobes. The wrapping of three ligand strands around two metallic centers by self-assembly affords robust…
Sulphur has been recognised as a growth promoter for carbon fibres and carbon nanotubes for over 30 years. Moreover, the Fe-C-S system, in particular, has been extensively studied for more than half a century in the fields of steelmaking and cast iron. In the present work we examine the role of sulphur in the iron-cat…
A theoretical investigation is carried out for predicting radiation characteristics of single-walled carbon nanotube (SWCNT) bundle dipole antennas based on the distributed circuit parameters and the model of an SWCNT, where the cross section of bundles can be in a circular and a rectangular geometry, respectively. Th…
Carbon nanotubes exhibit superior mechanical and electrical properties that make them attractive for developing new composite materials. In this research, we examined the properties of ultrafiltration membranes made from carbon nanotube/polymer composites. Multiwalled carbon nanotubes (MWCNT, 4% w/w) were incorporated…
Abstract Summary: The thermal degradation behavior of poly( ε ‐caprolactone) (PCL) and poly(L‐lactic acid) (PLA) have been studied in different environment. It was found that these polymers undergo completely different degradation processes in nitrogen and oxygen atmosphere. In oxygen environment PCL and PLA mainly de…
Nanotechnology is extensively used in industry and is widely explored for possible applications in medicine. However, its potential respiratory and systemic adverse effects remain unknown. Here pure titanium dioxide (TiO2) nanorods with rutile structure were prepared at room temperature by using a soft chemistry techn…
This paper discusses a new synthesis route to prepare microporous boron substituted carbon (B/C) materials that show a significantly higher hydrogen binding energy and physisorption capacity, compared with the corresponding carbonaceous (C) materials. The chemistry involves a pyrolysis of the designed boron-containing…
