Pectin-based hydrogels for biomedical applications have attracted recent attention due to their low cost, large availability of the materials, and high levels of biocompatibility. Specifically, periodate-oxidized pectin has been combined with chitosan and gelatin to form different structures. However, hydrogen peroxide-mediated oxidation of pectin has not been studied for this application; furthermore, there is little information on the effect of the degree of oxidation on hydrogel characteristics nor has the feasibility of these systems as controlled drug delivery matrices been explored.

Using action-derived molecular dynamics (ADMD), we study the dynamic folding pathway models of the Trp-cage protein by providing its sequential conformational changes from its initial disordered structure to the final native structure at atomic details. We find that the numbers of native contacts and native hydrogen bonds are highly correlated, implying that the native structure of Trp-cage is achieved through the concurrent formations of native contacts and native hydrogen bonds. In early stage, an unfolded state appears with partially formed native contacts (~40%) and native hydrogen bonds (

The three-dimensional complexity of the native extracellular matrix (ECM) suggests switching from 2D to 3D culture systems for providing the cells with an architecture more similar to the physiological environment. Reproducing the three-dimensionality in vitro can guarantee beneficial effects in terms of cell growth, adhesion, proliferation, and/or their differentiation. Hydrogels have the same tailorable physico-chemical and biological characteristics as ECM materials. In this study, we propose a thermoresponsive chitosan-based hydrogel that gels thanks to the addition of organic and inorgani

The high reactivity of the free silicon surface and its consequence: the “omnipresent” native silicon dioxide hinders the interface engineering in many processing steps of IC technology on atomic level. Methods known to eliminate the native oxide need in most cases vacuum processing. They frequently deteriorate the atomic flatness of the silicon. Hydrogen passivation by a proper DHF (diluted HF) treatment removes the native silicon oxide without roughening the surface while simultaneously maintains a “quasi oxide free” surface in a neutral or vacuum ambient for short time.

Hydrogels are hydrophilic, three dimensional polymers that imbibe large quantities of water while remaining insoluble in aqueous solutions due to chemical or physical cross-linking. The polymers swell in water or biological fluids, immobilizing the bioactive agent, leading to drug release in a well-defined specific manner. Thus the hydrogels’ elastic properties, swellability and biocompatibility make them excellent formulations for drug delivery. Currently, many drug potencies and therapeutic effects are limited or otherwise reduced because of the partial degradation that occurs before the adm

Abstract This chapter discusses the evolution of hydrogen policy in the European Union (EU) and related developments in key Member States. It examines the role of the EU as a global policy frontrunner and zooms in on the key measures used by the bloc to promote a hydrogen economy, with a focus on hard-to-abate sectors. It also analyses how the EU’s institutional nature as a supranational union of 27 Member States affects its emerging hydrogen sector as compared to other major economies. EU policy-making on hydrogen has been challenged by the bloc’s heterogeneity and structural disparities, with Member States having starkly diverging starting points, priorities, and competitive advantages when it comes to the energy transition and green industrial policy. Wealthier and more industrialised Member States have been able to offer generous domestic subsidies for hydrogen, in addition to benefiting from larger amounts of EU-level funding. As a future hydrogen importer, the EU has also put a growing emphasis on hydrogen in its foreign energy and climate policy, even though its hydrogen-related investments in third countries have been relatively limited to date. More recently, the EU, like other major economies, has grappled with the realisation that the green hydrogen economy will take longer to develop than originally anticipated. The persistently high costs of green hydrogen and the difficulties in mobilising demand in key sectors increase the uncertainty about hydrogen’s future role in the EU’s economy and in international trade.

AbstractAs one of the many energy alternatives, the interest in hydrogen-powered rail transport is gradually increasing worldwide, and some railway vehicles powered by hydrogen are currently in operation or undergoing experimental projects. However, due to the unsafe and unstable nature of hydrogen energy, hydrogen has potential leakage and explosion hazards in all rail transport applications. This paper summarizes the main application technologies of hydrogen safety in light of the research progress and unsafe factors in the process in the field of hydrogen-powered rail transport in various countries, at the same time clarifies the development challenges and difficulties of hydrogen-powered rail transport in the future, and makes suggestions for the development of hydrogen-powered rail transport safety in China.

Abstract Permeation curves analysis allowed us to point out the formation of an iron sulfide layer which is very adherent to the steel surface. The formation and then the evolution of this layer reduce in a very important way the hydrogen flow rate in the steel. The formation rate of this layer, therefore its protection capacity, increases with the H2S concentration decreasing and pH increasing. Chlorides do not affect the curve forms in a significant way. These different influences do not run for a very long time : after thirty hours, hydrogen flow rates seem to be unaffected by the sour aque

Deriving accurate cost projections associated with producing hydrogen within the context of an energy-export paradigm is a challenging feat due to non-deterministic nature of weather systems. Many research efforts employ deterministic models to estimate costs, which could be biased by the innate ability of these models to �see the future�. To this end we present the findings of a multistage stochastic model of hydrogen production for energy export (using liquid hydrogen or ammonia as energy vectors), the findings of which are compared to that of a deterministic programme.

Abstract Sour well design is often based upon the partial pressure of the acid gases, which have most often been correlated to equivalent partial pressures in laboratory studies conducted at a much lower total pressure. This partial pressure approach is supported by industry standards, notably ISO 151561 / NACE MR01751. However, total pressure and temperature, as seen in the wells, will impact the solubility and chemical behavior of these acid gases in the water phase, in some instances potentially reducing the corrosive impact by a factor of 3-10, depending upon the potential critical paramet

Abstract The development of a new paradigm in materials characterization is underway in which hydrogen and other crucial material properties are monitored to allow accurate mitigation of problems before damage can occur. Hydrogen is notorious for its dynamic, hard-to-detect, and corrosive nature in materials. In many cases, hydrogen damage is responsible for failures in which hydrogen was never attributed as the cause, including many cases commonly ascribed to stress corrosion cracking and a variety of other failure mechanisms. Non-destructive sensors have been developed for rapid determinatio

Abstract Hydrogen peroxide has been evaluated in a pilot cooling tower system as an alternative to continuous chlorination and intermittent dosing with non-oxidizing biocides. Hydrogen peroxide demand in the cooling system was considerably higher than predicted based on its vapor pressure and spontaneous decomposition in alkaline waters. This might be explained by the selection of peroxidase and catalase positive organisms in the cooling water which decompose hydrogen peroxide to water and oxygen. Although continuous feed of 2 to 3 ppm of hydrogen peroxide failed to control the bulk water bact

Abstract The challenges in characterising susceptibility of corrosion resistant alloys (CRAs) to hydrogen embrittlement in service are highlighted using experimental data for duplex stainless steels (DSSs) in two major industrial applications: in oil production environments downhole, where galvanic coupling to carbon steel can cause hydrogen uptake, and in subsea pipelines where cathodic protection provides the source of hydrogen atoms. The influence of environment composition, charging current, pre-exposure, time, temperature, temperature excursions, and mechanical test method is examined. Fo

In the context of decarbonization, green hydrogen (H2) could play a relevant role alongside electrification in meeting the energy needs of those activities that require high temperatures and great flexibility with no other alternatives currently available. However, it faces significant obstacles to its large-scale and commercial use due to its storage and transport limitations, low volumetric and energy density, and flammable nature. There are various solutions or hydrogen carriers for its transport and storage, which depend, among others, on the end use. Among the different carrier alternativ

The Lower Triassic Montney Formation is a major siltstone dominated unconventional tight gas play in the Western Canadian Sedimentary Basin (WCSB). In the Peace River region, the Montney Formation contains a regionally variable amount of hydrogen sulfide (H2S) in gas-producing wells with western Alberta's wells having the highest concentrations. Previous studies on the source and distribution of H2S in the Montney Formation mainly focused on variations of H2S concentration and its relationship with other hydrocarbon and non-hydrocarbon gases, sulfur isotope composition of H2S, as well as organ

This report analyzes the possible evolution of the hydrogen transport infrastructure system in the Basque Country in the medium term. The objective of the work is threefold: (1) to characterize medium-term infrastructure development scenarios (over a 10-15 year horizon); (2) to identify key factors that influence the development of the Basque hydrogen system and analyze their potential impact on the determination of the medium-term scenario; (3) to draw conclusions of a strategic nature for the Basque Country. The hydrogen production-transport system scenarios analyzed range from a totally dec

Freshwater ecosystems in mountain areas are considered important water resources and biodiversity hotspots that are highly sensitive to changes in climate. The Alpine region is known to be particularly affected by climate change, including changes in hydrological extremes such as droughts and floods, which are expected to become more frequent and intense. Despite the importance of groundwater as a primary water resource, climate change impacts on groundwater quality, including those resulting from hydrological extremes, have been rarely addressed to date. Moreover, groundwater monitoring is cu

Hydraulic fracturing is a reservoir stimulation technique that involves the injection of high-pressure fluids to enhance recovery from unconventional hydrocarbon reservoirs. Often this involves the injection of surface waters (along with additives such as biocides) into formational fluids significantly different isotopic and geochemical compositions facilitating geochemical fingerprinting of these fluid sources. In some instances, the produced fluids experience an increase in hydrogen sulfide (H2S) concentration over the course of production resulting in an increased risk to health and safety,

Near-to-surface geothermal energy with heat pumps is state of the art and is already widespread in Switzerland. In the future energy system, medium-deep to deep geothermal energy (1 to 6 kilometres) will, in addition, play an important role. To the forefront is the supply of heat for buildings and industrial processes. This form of geothermal energy utilisation requires a highly permeable underground area that allows a fluid – usually water – to absorb the naturally existing rock heat and then transport it to the surface. Sedimentary rocks are usually permeable by nature, whereas for granites
