Analysis of EXAFS data measured on a material with a disordered local configuration environment around the absorbing atom can be challenging owing to the proliferation of photoelectron scattering paths that must be considered in the analysis. In the case where the absorbing atom exists in multiple inequivalent sites,…
A novel fused acceptor-donor-acceptor (A-D-A) type panchromatically electrochromic compound was synthesized. It exhibited intensive absorption bands covering entire UV-vis and near-infrared regions upon reduction to the radical anionic state, owing to the simultaneous presence of π*-π* transitions and intervalence cha…
This article describes some of the activities of the IUCr Diffraction Data Deposition Working Group and introduces a collection of articles discussing the archiving of diffraction images.
The combination of an antifungal agent and drug carrier with adjunctive antimicrobial properties represents novel strategy of complex therapy in pharmaceutical technology. The goal of this study was to investigate the unmodified and ion cross-linked chitosan's influence on anti-Candida activity of clotrimazole used as…

Thermopower waves are a recently developed energy conversion concept utilizing dynamic temperature and chemical potential gradients to harvest electrical energy while the combustion wave propagates along the hybrid layers of nanomaterials and chemical fuels. The intrinsic properties of the core nanomaterials and chemi…
Sensitive and selective H2O2 detection: Chemiluminescent nanoparticles are fabricated utilizing fluorogens with aggregation-induced emission characteristics and a H2O2-responsive molecule. The obtained nanoparticles not only exhibit good response to H2O2 in vitro but also show high chemiluminescence in vivo using an L…
In the process of preparing core–sheath fibers via coaxial electrospinning, the relative evaporation rates of core and sheath solvents play a key role in the formation of the core–sheath structure of the fiber. Both silk fibroin (SF) and poly(lactide-co-ε-caprolactone) (PLCL) have good biocompatibility and biodegradab…
Abstract Highly crystallized hexagonal boron nitride (h‐BN) sheets were obtained by a versatile method modifying the original synthesis by using an additive agent and, as a consequence, decreasing the temperature for the ceramization step (1200–1400 °C). This synthesis is based on the polymer‐derived ceramics (PDCs) r…
Adequate vascularization in biomaterials is essential for tissue regeneration and repair. Current models do not allow easy analysis of vascularization of implants in vivo, leaving it a highly desirable goal. A tool that allows monitoring of perfusion capacity of such biomaterials noninvasively in a cheap, efficient, a…
In this paper, we show how the electromagnetic phenomena in moving magnetodielectric media can be emulated using artificial composite structures at rest. In particular, we introduce nonreciprocal periodically loaded transmission lines, which support waves obeying the same rules as plane electromagnetic waves in moving…
Optical phonons are employed to probe a structural phase transition of IrTe Se x at K for x = 0 and K for x = 0.45, which is dictated by Ir dimerization with charge modulations. Phonon Raman spectra show a discontinuous change at T C and thermal hysteresis. A mode involving out-of-plane motions of Te atoms is mostly a…
Inspirations found in nature became more and more famous for an innovative product development. An interdisciplinary approach of scientifi c research and industrial development has shown that identifi cation and transfer of biological principles to technical applications uncover secrets of specifi c adaptations result…
The interaction of chemical vapor deposition (CVD)-grown graphene films with water was studied by means of in situ angle-dependent X-ray absorption spectroscopy (XAS). We found that when the graphene layer is in contact with water there is a reduction in the π* peak intensity in the carbon K-edge absorption spectra, a…
The nanostructuring of rutile MnO 2 has been demonstrated to improve its performance for electrochemical storage and catalysis. Despite the progress of recent experimental works in exploiting this to enhance the material’s performance in important technological systems such as Li-ion batteries the detailed atomic-scal…
In this paper, new steps toward a better understanding and utilization of high-pressure high-temperature nanodiamonds (NDs) containing nitrogen-vacancy (NV) centers have been taken. NV – -related long-term luminescence of oxygenated particles increased in comparison to plasma hydrogenated NDs’ NV – luminescence. The o…
The present study was designed to evaluate the biocompatibility of nanoparticles polyethylene glycol (PEG)-poly L-lysine (PLL)-poly lactic-co-glycolic acid copolymer (PLGA) (PEG-PLL-PLGA) before clinical application. We applied some tests to assess the safety of PEG-PLL-PLGA nanoparticles (NPs). There was low cytotoxi…
This paper addresses the preparation of one-dimensional nanostructured polyaniline (PANI) and polypyrrole (PPy). The Fourier transform infrared spectroscopy was used to characterize the chemical structure of the samples. The morphology of the samples was investigated by scanning electron microscopy and transmission el…
The bacterium Azotobacter vinelandii produces a family of seven secreted and calcium-dependent mannuronan C-5 epimerases (AlgE1-7). These epimerases are responsible for the epimerization of β-D-mannuronic acid (M) to α-L-guluronic acid (G) in alginate polymers. The epimerases display a modular structure composed of on…
