A number of non-covalently bound donor-acceptor dyads, consisting of C60 as the electron acceptor and cycloparaphenylene (CPP) as the electron donor, have been reported. A hypsochromic shift of the charge transfer (CT) ...
In this shortnote, we present the results of a geochronological study of the last eruption in the volcanic region of the Garrotxa (NE Iberian Peninsula). Four 14 C analysis of organic matter contained in palaeosols located ...
La regulació legal dels camins de ronda, dels itineraris per fer a peu i a través dels quals es pot resseguir el nostre litoral, és relativament recent. I és que, tot i haver estat utilitzats des de segles pels pescadors o ...
Sobre l'estat de la qüestió de la Guerra de Succesió a Cataluya des d'un punt de vista historiogràfic
In pigs, ejaculate is expelled in fractions, mainly the sperm-rich fraction (SRF) and the post-SRF (PSRF), which differ in both sperm content and origin. In addition, intra-ejaculate variability between fractions in terms ...
Onconase® FL-G zymogen is a 120 residue protein produced by circular permutation of the native Onconase® sequence. In this construction, the wild type N- and C-termini are linked by a 16 residue segment and new N- and ...
Pyrazinones (2(1H)-pyrazinones) are found as components of a range of natural substances and are involved in the preparation of a great number of bioactive molecules. Synthesis of such compounds, and analogues, requires ...
Polyalkyne and enediyne azamacrocycles are prepared from arenesulfonamides and various alkyne and alkene derivatives either under basic or neutral conditions. The new family of macrocyclic substrates is tested in the [2+2+2] ...
Introduction Exposure biomarkers are required in tobacco use studies to accurately assess smoking status since self-reporting usually results in misclassification estimates. This study uses breath analysis and assesses ...
Electrochemical conversion of CO2 into added-value chemicals is an important approach to recycle CO2. In this work, we have combined the most efficient metal catalysts for this reaction (Cu, Ag, and Au) considering dispersed ...
Cardiopulmonary resuscitation (CPR) is a first-aid key survival technique used to stimulate breathing and keep blood flowing to the heart. Its effective administration can significantly increase the survival chances of ...
A large number of 2D/2D and 3D/3D aromatic fusions that keep their aromaticity in the fused compounds have been synthesized. In addition, we have previously proven the electronic relationship between the 3D aromaticity of ...
Nowadays, research in autonomous underwater manipulation has demonstrated simple applications like picking an object from the sea floor, turning a valve or plugging and unplugging a connector. These are fairly simple tasks ...
This paper addresses the problem of object recognition from colorless 3D point clouds in underwater environments. It presents a performance comparison of state-of-the-art global descriptors, which are readily available ...
In this paper, we present an information-theoretic framework to compute the shape similarity between 3D polygonal models. Given a 3D model, an information channel between a sphere of viewpoints around the model and its ...
This paper tackles the problem of generating world-scale multi-resolution triangulated irregular networks optimized for web-based visualization. Starting with a large-scale high-resolution regularly gridded terrain, we ...
Biodegradable stents (BRS) offer enormous potential but first they must meet five specific requirements: (i) their manufacturing process must be precise; (ii) degradation should have minimal toxicity; (iii) the rate of ...
Biomedical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare purposes. Much of the work in biomedical engineering consists of research and development, ...
Addition of benzyne to carbon nanostructures can proceed via (4+2) (1,4-addition) or (2+2) (1,2-addition) cycloadditions depending on the species under consideration. In this work, we analyze by means of density functional ...
S'ha explorat la influència de diferents fragments (LRu)nII (L = Cp– (n = 1, 2); C6H6) η6 coordinats amb corannulè (CpRu+, (benzè)Ru2+ i (CpRu)22+ mitjançant l'activació. Model de soca (ASM) de reactivitat juntament amb ...
