431. Bioactivity of polyphenols: Preventive and adjuvant strategies toward reducing inflammatory bowel diseases-promises, perspectives, and pitfalls
Date: 03-11-16 

Inflammatory bowel diseases (IBDs) are characterized by autoimmune and inflammation-related complications of the large intestine (ulcerative colitis) and additional parts of the digestive tract

432. Phase separation in NiCrN coatings induced by N2 addition in the gas phase: A way to generate magnetic thin films by reactive sputtering of a non-magnetic NiCr target
Date: 03-11-16 

Magnetic coatings are used for a lot of applications from data storage in hard discs, spintronics and sensors. Meanwhile, magnetron sputtering is a process largely used in industry for the deposition

433. Secondary phase formation during monoclinic Cu2SnS3 growth for solar cell application
Date: 20-10-16 

Cu2SnS3 is investigated as a potential solar absorber material, which is known to exist in several polymorphs. In the present work, the transition to the most efficient monoclinic polymorph is

434. Additive fabrication of nanostructures with focused soft X-rays
Date: 13-10-16 

We report on a novel technique for the fabrication of metallic nanostructures via soft X-ray irradiation of precursor molecules supplied from the gas phase. With this technique we were able to

435. Transfer of a static PCA-MSPC model from a steady-state anaerobic reactor to an independent anaerobic reactor exposed to organic overload
Date: 06-10-16 

A static multivariate statistical process control model based on principal component analysis (PCA-MSPC) was developed for an anaerobic reactor maintained in steady-state, joining the biogas

436. Identification of reference genes for RT-qPCR data normalization in Cannabis sativa stem tissues
Date: 19-09-16 

Gene expression profiling via quantitative real-time PCR is a robust technique widely used in the life sciences to compare gene expression patterns in, e.g., different tissues, growth conditions, or

437. Inverse barocaloric effects in ferroelectric BaTiO3 ceramics
Date: 22-09-16 

We use calorimetry to identify pressure-driven isothermal entropy changes in ceramic samples of the prototypical ferroelectric BaTiO3. Near the structural phase transitions at -400 K

438. Multiple strain-induced phase transitions in LaNiO3 thin films
Date: 16-09-16 

Strain effects on epitaxial thin films of LaNiO3 grown on different single crystalline substrates are studied by Raman scattering and first-principles simulation. New Raman modes, not present in bulk

439. Theory of antiferroelectric phase transitions
Date: 25-07-16 

At variance with structural ferroic phase transitions which give rise to macroscopic tensors coupled to macroscopic fields, criteria defining antiferroelectric (AFE) phase transitions are still under

440. Aspect ratio improvement of ZnO nanowires grown in liquid phase by using step-by-step sequential growth
Date: 22-07-16 

ZnO is a semiconductor with a direct band gap (3.37 eV) and a large exciton binding energy (60 meV) at room temperature. ZnO nanowires have shown advantages in the sensing field and optoelectronics
