Computational Analyses of CO2 Electroreduction and C Interactions with Transition Metals
Catalysis is ubiquitous in chemical industries since it accelerates chemical reactions, thereby saving considerable amounts of energy. Most catalytic processes in industry are heterogeneous in nature, typically involving ...
Technical and economic evaluation of anaerobic membrane bioreactors for municipal wastewater treatment
Anaerobic membrane bioreactor (AnMBR), which is a combination of membrane separation and anaerobic digestion, is an emerging biotechnology for municipal sewage treatment. The application of AnMBRs in the mainline of ...
Ti-containing hybrid organosilicas, Mo(x)C/g-C(3)N(4) nanocomposites and engineered Mo(x)C/TiO(2) nanomaterials as noble-metal-free photocatalysts for H(2) production
The photocatalytic hydrogen production is considered an environmentally promising and friendly method, which could lead to achieve clean and renewable hydrogen and contribute in the future to store solar energy as chemical ...
Actividad de la proteina intrínsecamente desordenada p15(PAF) en el replisoma o cómo el desorden orquesta la replicación celular
La abrazadera deslizante eucariota (PCNA), juega un papel esencial como componente del replisoma. PCNA, de forma toroidal, rodea el DNA y ata las polimerasas y otros factores a la plantilla genómica para una síntesis ...
Advanced Modelling of Metallic Nanomaterials for Catalysis
Nanoparticles are highly relevant for catalysis due to their nanostructure, which increases the fraction of surface atoms, and the size dependent morphology and properties. Catalytic properties of nanoalloys also depend ...
Engineered nanomaterials release from nano-enabled products
The increased presence of nano-enabled products in multiple applications has raised concerns about its potential risks to human health and the environment. Therefore, there is a need for a responsible and coordinated ...
Syntheses of (S)-Bicalutamide and Somatostatin analogs, and development of Green procedures for Peptide synthesis
Peptides are defined as compounds that contain between two and fifty amino acids connected together by amide bonds. Inside our body, peptides are natural biological messengers that play critical roles in human physiology ...
Computational modeling of transition metals carbides with relevant to nanotechnology and catalysis
The work carried out in this thesis is based on the study of transition metal carbides (TMCs) as catalysts study from a theoretical point of view, using the techniques of Computational Chemistry. TMC materials have been ...
Photoswitchable allosteric ligands to modulate metabotropic glutamate receptors
Photopharmacology has the main purpose to allow the control of protein activity with light. The most exploited strategy used to achieve this objective is the freely diffusible photopharmacology and it is based in the use ...
Nanostructured transition metal carbides as potential catalysts for greenhouse gases conversion
Over the recent decades, several studies revealed the precarious climate situation which is threatening all Life forms on earth, including mankind, even if sometimes we tend to ignore the actual fragility of our situation. ...
Cosymlib: a Python library for continuous symmetry measures and its application to problems in structural chemistry
For many years symmetry has been a useful concept in the study of the spatial organization of atoms in molecules or solids. The presence of symmetry elements in a given molecular structure gives a valuable information about ...
Origin and release of cyanotoxins in surface water reservoirs
Cyanobacteria are prokaryotes and components of regular periphyton formation. Overall, there are around 2000 cyanobacterial species that live in various environments. Some cyanobacterial species are known to form blooms, ...
Study of transition metal carbide catalysts of group 5 in the RWGS reaction
Nowadays there is a growing interest in the capture and utilization of CO2 because of the increase of its concentration in the atmosphere. Captured CO2 can be recycled through different processes to obtain several value-added ...
Development and applications of photoswitchable small molecules and peptides to control protein-protein interactions and GPCR activity
Photopharmacology is an emerging field that relies on the development of photosensitive compounds to enable precise spatiotemporal control over endogenous proteins. Photochromic ligands· are designed to respond ...
