"Focusing on the cutting-edge technologies available in the field of photovoltaics, Solar Cell Nanotechnology explores the latest research and development activities related to organic, inorganic, and hybrid materials being used in solar cell manufacturing. Several chapters are dedicated to explaining the fundamentals…
Ultrahigh piezoelectric constant (d33 = 683 pC/N) and converse piezoelectric coefficient (dS/dE = 1257 pm/V) were observed in CuO-doped lead-free (Ba,Ca)(Ti,Sn)O3 ceramics at an optimal composition fabricated by a conventional sintering method at a low temperature 1250 °C. Since all samples showed a pure perovskite st…
Multidrug resistance (MDR) is a hallmark of cancer cells and a crucial factor in chemotherapy failure, cancer reappearance, and patient deterioration. We have previously described the physicochemical characteristics and the in vitro anticancer properties of a multifunctional doxorubicin-loaded liposomal formulation. L…
A novel method of fabricating titanium superhydrophobic surfaces by ultrafast laser irradiation is reported. The ultrafast laser irradiation creates self-organized microstructure superimposed with nano-scale roughness, after which a fluoropolymer coating is applied to lower the surface energy of the textured surface a…
To improve the efficacy of gemcitabine (GEM) for the treatment of advanced pancreatic cancer via local hyperthermia potentiated via a multi-functional nanoplatform permitting both in vivo heating and drug delivery is the goal of this study. Here, a chemohyperthermia approach to synergistically achieve high intra-tumor…
The protective coating on mussel (Mytilus galloprovincialis) byssus has attracted considerable research interest because of its excellent mechanical properties such as hardness and extensibility. These special properties are known to be highly related with specific interactions between mussel foot protein-1 and metal…
A search for novel organic luminogens led us to design and synthesize some N-fused imidazole derivatives based on imidazo[1,2-a]pyridine as the core and arylamine and imidazole as the peripheral groups. The fluorophores were synthesized through a multicomponent cascade reaction (A(3) coupling) of a heterocyclic azine…
In this study, we develop a series of new materials that can simultaneously and reversibly self-heal without external stimuli based on metallo-supramolecular interactions. Multiple tridentate 2,6-bis(1,2,3-trizaol-4-yl)pyridine (BTP) ligand units synthesized via a copper-catalyzed azide–alkyne cycloaddition (CuAAC) “c…
We report on the isotropic pinning obtained in epitaxial Fe(Se,Te) thin films grown on CaF2(001) substrate. High critical current density values – larger than 1 MA/cm2 in self field and liquid helium – are reached together with a very weak dependence on the magnetic field and a complete isotropy. Analysis through tran…
We have investigated atomistic and electronic mechanisms of hydrogen embrittlement at grain boundaries of iron in the presence and absence of vacancies by using first-principles calculations. Considering interactions between hydrogen, vacancies, and $\ensuremath{\Sigma}$3 grain boundaries in $\ensuremath{\alpha}$-Fe,…
The magnetic phase separation and exchange bias effect in off-stoichiometric Ni2Mn1.4Ga0.6 alloy were reported. Spontaneous exchange bias after zero-field cooling was observed in this alloy. The magnetic nature of ground state was characterized as phase separation with non-percolated ferromagnetic domains in spin glas…
PURPOSE: The purpose of this study was to examine the therapeutic effect of magnetic nanoparticle hyperthermia (mNPH) combined with systemic cisplatin chemotherapy in a murine mammary adenocarcinoma model (MTGB). MATERIALS AND METHODS: An alternating magnetic field (35.8 kA/m at 165 kHz) was used to activate 110 nm hy…
Fuel additives incorporating nanosized ceria have been increasingly used in diesel engines as combustion promoters. However, few studies have assessed the impact of these nanotechnology-based additives on pollutant emissions. Here, we systematically compare emission rates of particulate and gaseous pollutants from a s…
In order to deduce the molecular mechanisms of biological function, it is necessary to monitor changes in the subcellular location, activation, and interaction of proteins within living cells in real time. Förster resonance energy-transfer (FRET)-based biosensors that incorporate genetically encoded, fluorescent prote…
The ultrafast exciton photodynamics of red-emitting and blue-emitting colloidal Si nanocrystals are contrasted under low (1.5 mJ/cm 2 ) and high (9.1 mJ/cm 2 ) excitation powers with broadband transient absorption spectroscopy. While the low-power initiated transient signals differ strongly for the two samples, the hi…
Five novel organic conjugated derivatives containing multifraction twisted acene units have been synthesized and characterized. These compounds and the model molecule 2-methyl-5,12-diphenyl-6:7,10:11-bisbenzotetracene emit strong blue light in diluted solution with quantum yields of 0.21-0.67, while in the solid state…
This paper investigates the design of novel polyelectrolyte complex (PEC) coacervates of chitosan (Ch) with gum Odina (GO) as potential candidates for colon targeting. Potentiometric titration experiments established that 1:1 charge stoichiometry occurred at a Ch/GO weight ratio of 1:5. The coacervate formed at pH 4.5…
The aim was the fabrication of glycodendrimer encapsulation agents with high proportions of cyclodextrins ( CDs ) to maintain the biocompatibility properties, as well as to notably improve their ability to load various suitably sized drugs. The novel glycodendrimers contained β ‐ CD in both core and branches, namely β…
In order to investigate the effects of in-plane strain on the superconductivity of FeSe, epitaxial thin films of FeSe were fabricated on CaF2 substrates. The films are compressed along the a-axis and their superconducting transition temperatures Tczero reach 11.4 K, which is approximately 1.5 times higher than that of…
An intense visible yellow-orange emission with long lifetime and enhanced quantum yield has been achieved for a metal-organic framework based on a highly light-harvesting dyclo-metalated iridium(III) unit, which shows effective detection of nitroaromatic explosives on the ppm scale.
