The main obstacles to cancer therapy are the inability to target cancer cells and the acquired drug resistance after a period of chemotherapy. Reduced drug uptake and DNA repair are the two main mechanisms involved in cisplatin resistance. In the present investigation, canthaplatin, a Pt(iv) pro-drug of cisplatin and…
Our results demonstrate that in addition to being used for controlling morphology during calcite growth, polysaccharide (PS) that has been designed for biomineralization is also extremely robust, influencing calcite reactions even after millions of years. We investigated calcite (CaCO 3 ) behavior in solutions with ve…
Nanofibre forming peptide amphiphiles were conjugated to naproxen through an esterase-sensitive linker. The amount of naproxen released, in the presence of enzymes, was influenced by the linker conjugating the drug to the supramolecular assembly. In vitro studies showed the anti-inflammatory activity of the released d…
ABSTRACT The hydrolyzed soy protein isolate (HSPI) with different hydrolysis degree was applied to modify urea‐formaldehyde resins (UF) via copolymerization process. The properties of HSPI were characterized by attenuated total reflection Fourier transform infrared spectroscopy (ATR‐FTIR) and TGA. The results show tha…
We use the rotating polarizer birefringence technique to investigate the properties of dislocations in single crystalline diamond produced by a high pressure high temperature (HPHT) process or by microwave plasma assisted chemical vapor deposition (MPACVD). The birefringence pattern of individual dislocations is measu…
Development of drug resistance is a central challenge to the treatment of ovarian cancer. Metronomic chemotherapy decreases the extent of drug-free periods, thereby hindering development of drug resistance. Intraperitoneal chemotherapy allows for treatment of tumors confined within the peritoneum, but achieving sustai…
A series of NLO chromophores a–d bearing thieno[3,2- b ]thiophene (TT) as the conjugated bridge or the lateral moiety have been synthesized and investigated.
A new relaxor ferroelectric ceramics, Sr 4 CaBiTi 3 Nb 7 O 30, were prepared. The microstructure, morphology, dielectric, and ferroelectric properties were studied. The ceramics were found that growing in some directions preferentially. Two dielectric relaxations were observed below the Burns temperature T B = 460 K a…
The influence of agitation and fluid shear on nucleation of m -hydroxybenzoic acid polymorphs from 1-propanol solution has been investigated through 1160 cooling crystallization experiments. The induction time has been measured at different supersaturations and temperatures in two different crystallizer setups: small…
The current study investigated the interaction of sterically stabilized OECD standard Ag ENP (AgNM-300k) and silver ions (Ag+) in 25 German arable soils with varying properties (organic carbon concentration of 0.4-25 mg g(-1) and clay content of <0.1-392 mg g(-1)) in 24 h batch retention experiments. A soil subset (n=…
BACKGROUND: Optimizing liposomal vehicles for targeted delivery to the brain has important implications for the treatment of brain tumors. The promise of efficient, brain-specific delivery of chemotherapeutic compounds via liposomal vehicles has yet to be achieved in clinical practice. Intra-arterial injection of spec…
Using first-principles calculations we studied the electric field enhancement in polyacene molecules upon illumination. These molecules can be seen as a specific class of C-based (i.e., graphene-derived) nanostructures, recently proposed as alternative materials for plasmonics. We demonstrate that optical transitions…
Abstract We report first‐principles DFT calculations of the single‐layer VS2 work function, the experimental synthesis of flower‐like few‐layer‐thick VS2 nanosheets by a simple one‐step hydrothermal method, and the investigation of their field emission properties. The turn‐on field required to draw emission current de…
The dynamics of droplets impinging on different microtextured superhydrophobic surfaces are modeled with CFD combined with VOF (Volume of Fluid) technique. The method is validated by experimental data and an analytical model (AM) that is used to predict the penetrating depth and the maximum spreading diameter of an im…
Transparent paper made of cellulose for next generation 'green' electronic devices is a completely new concept that has attracted great attention over the past decade due to a variety of prominent properties of cellulose such as its natural origin, environmental safety and renewability. Various proof-of-concept transp…
Two-component super-hydrogelation triggered by the acid–base interaction of a L-histidine appended pyrenyl derivative (PyHis) and phthalic acid (PA) was reported. The use of isomeric isophthalic or terephthalic acid or other comparable acids in place of PA does not lead to salt formation and therefore hydrogelation is…
We successfully designed a series of new polymers to further boost the efficiency of polymer–PbS QD hybrid bulk heterojunction solar cells. We also systematically investigated the effect of polymer structures and quantum dot size on the device performance.
A series of poly(4- tert -butylstyrene- block -2-vinylpyridine) [P(tBuSt- b -2VP)] block copolymers (BCPs) with varying volume fractions, molecular weights, and narrow dispersities were synthesized from the commercially available monomers by sequential living anionic polymerization. The copolymers were thoroughly char…
Reductive metalation of [44]decaphyrin with [Pd2(dba)3] provided a Hückel aromatic [46]decaphyrin Pd(II) complex, which was readily oxidized upon treatment with DDQ to produce a Hückel antiaromatic [44]decaphyrin Pd(II) complex. In CH2Cl2 solution the latter complex underwent slow tautomerization to a Möbius aromatic…
We study in momentum-conserving systems, how nonintegrable dynamics may affect thermal transport properties. As illustrating examples, two one-dimensional (1D) diatomic chains, representing 1D fluids and lattices, respectively, are numerically investigated. In both models, the two species of atoms are assigned two dif…
