Purpose: To formulate and evaluate temperature-sensitive, controlled-release camptothecin hydrogel for anticancer drug delivery.Method: Temperature-sensitive hydrogel based on chitosan/β-glycerophosphate (β-GP)/β-cyclodextrin (β-CD) was prepared by crosslinking method. The formulations were characterized by Fourier tr…
Boron doped diamond (BDD) single crystals have been grown under conditions of high isostatic pressure by the temperature gradient method. Numerous equilateral triangles were found on the fluorescence images of {111}-diamond facets. Structural peculiarities of BDD were investigated by JEM-2010 transmission electron mic…
Constant swirls of innovative ideas are starting to push composites and hybrid metal-composite components for use in an ever expanding circle of products. Recent discoveries of Graphene/Au composites have invigorated innovations for its application to aerospace and space products. Attributes such as a low CTE, stiffne…
Mesoporous TiO 2 nanoparticles were synthesized via a fast and classical sol–gel method, respectively. Polyacrylamide was used as the template in the fast sol–gel route; the polymerization crosslink by hydrogen bonds between the template and hydrolysates of Ti alkoxides shortens the reaction time from several days to…
Novel macrocyclic amine-linked oligocarbazole hollow microspheres are synthesized via a one-step oxidative method in aqueous solution. Upon altering the oxidants and acidic media, the average diameters of the obtained hollow microspheres are tunable from 0.23 to 2.0 μm. With attractive amine and carbazole functionalit…
Quantitative pharmacokinetic analysis of methoxy-poly(ethylene glycol) (mPEG) and mPEGylated molecules is important for clinical drug development. Here we developed sensitive sandwich and competitive ELISAs by expressing an anti-mPEG antibody on the surface of fibroblasts for effective capture of mPEG molecules in bio…
Enzymatic isolation of chondrocytes from a cartilage biopsy is the first step to establish in vitro models of chondrogenesis or to generate cell-based grafts for cartilage repair. Such process is based on manually operated procedures and typically results in yields lower than 20% of the total available cells. In this…
Over the last decade, significant advances in chemical inhibition have enabled operators to use carbon steel pipework in oil and gas facilities where sand production is a concern. The ability of these inhibitors to reduce both the electrochemical corrosion reactions and the mechanical damage attributed to particle imp…
Cationisation allows cotton to be dyed with anionic dyestuffs (including anionic pigment dispersions) without the need for salt, and with decreased usage of dye, water, and energy. Appropriate cationisation levels play a part in dyeing properties such as fabric levelness, in fastness properties such as lightfastness,…
In this paper, we report a UV/ozone-assisted method for low temperature preparation of mesoporous TiO2 with controlled crystalline phase. The results showed that the crystallization of mesoporous TiO2 can occur at temperatures as low as 100 °C under UV/ozone irradiation. Highly crystalline mesoporous anatase TiO2 was…
Although there are many stimulus-responsive polymers, poly(N-isopropyl acrylamide) (pNIPAM) is of special interest due to the phase change it undergoes in a physiologically relevant temperature range that leads to the release of cells and proteins. The nondestructive release of cells opens up a wide range of applicati…
Urease is a nickel-dependent metalloenzyme that catalyzes the hydrolysis of urea to form ammonia and carbon dioxide. Although the enzyme serves a significant role in several detoxification and analytical processes, its usability is restricted due to high cost, availability in small amounts, instability, and a limited…
Here we demonstrate the controllability on morphology of hydrothermal ZnO nanowires through the critical concentration for nucleation. When Zn ion concentration is relatively low, the nucleation process preferentially occurs on the (0001) plane, promoting nanowire growth. In contrast, for relatively high Zn ion concen…
We introduce a novel transmission electron imaging method to clarify the internal structure of single whole cells by scanning electron microscopy (SEM). In this method, whole cells are cultivated on a transparent flat plate in advance, which is made of a scintillator that emits photons by irradiating an electron beam.…
We investigate some applications of the differential subordination and the differential superordination of certain admissible classes of multivalent functions in the open unit disk U . Several differential sandwich-type results are also obtained.
We quantitatively evaluate Nuflare’s latest resist charging effect correction (CEC) model for advanced photomask production using e-beam lithography. Functionality of this CEC model includes the simulation of static and timedependent charging effects together with an improved calibration method. CEC model calibration…
Overcoming the challenges associated with photomask defectivity is one of the key aspects associated with EUV mask infrastructure. In addition to establishing specific EUV mask repair approaches, the ability to identify printable mask defects that require repair as well as to verify if a repair was successful are abso…
We develop an electrodynamic model based on dyadic Green's functions for analyzing the near-field interactions between a dipolar scatterer (DS) and a plasmonic nanosphere (PN) under external excitation, accounting for multipolar contributions in the evaluation of the scattered fields. In particular, we include all the…
We use nuclear resonance inelastic x-ray scattering (NRIXS), a relatively new, synchrotron-based, isotope-specific technique in combination with a more traditional one, Raman spectroscopy, to probe the vibrational dynamics of the host frameworks in two Zintl clathrates: ${\mathrm{K}}_{8}{\mathrm{Zn}}_{4}{\mathrm{Sn}}_…
Synchrotron X-ray radiography was utilized to visualize a miniature fuel cell with an active area of 0.48 cm2 at an effective spatial resolution of 10 μm and 3 seconds per frame. Water in GDLs with MPL thicknesses of 0, 50, 100, 150 μm and 50 μm without a macro-substrate was quantified while the cell was operated at 0…
