Abstract:
AbstractThe application of uranyl salts as powerful photoredox catalysts in chemical transformations lags behind the advances achieved in thermocatalysis and structural chemistry. In fact, uranyl cations (UO2 2+) have proven to be ideal photoredox catalysts in visible-light-driven chemical reactions. The excited state of uranyl cations (*UO2 2+) that is generated by visible-light irradiation has a long-lived fluorescence lifetime up to microseconds and high oxidizing ability [E o = +2.6 V vs. standard hydrogen electrode (SHE)]. After ligand-to-metal charge transfer (LMCT), quenching occurs with organic substrates via hydrogen-atom transfer (HAT) or single-electron transfer (SET). Interestingly, the ground state and excited state of uranyl cations (UO2 2+) are chemically inert toward oxygen molecules, preventing undesired transformations from active oxygen species. This review summarizes recent advances in photoredox transformations enabled by uranyl salts.1 Introduction2 The Application of Uranyl Photoredox Catalysis in HAT Mode3 The Application of Uranyl Photoredox Catalysis in SET Mode4 Conclusion and Outlook

Abstract:
Nanoscale composites consisting of silver and silver halide (Ag–AgX, X = Cl, Br, I) have attracted much attention as a novel type of visible-light photocatalyst (the so-called plasmonic photocatalysts), for solar-to-chemical transformations. Support-free Au–Ag alloy nanoparticle-incorporated AgBr crystals (Au–Ag@AgBr) were synthesized by a photochemical method. At the initial step, Au ion-doped AgBr particles were prepared by adding an aqueous solution of AgNO3 to a mixed aqueous solution of KBr and HAuBr4. At the next step, UV-light illumination (λ = 365 nm) of a methanol suspension of the resulting solids yielded Au–Ag alloy nanoparticles with a mean size of approximately 5 nm in the micrometer-sized AgBr crystals. The mole percent of Au to all the Ag in Au–Ag@AgBr was controlled below < 0.16 mol% by the HAuBr4 concentration in the first step. Finite-difference time-domain calculations indicated that the local electric field enhancement factor for the alloy nanoparticle drastically decreases with an increase in the Au content. Also, the peak of the localized surface plasmon resonance shifts towards longer wavelengths with increasing Au content. Au–Ag@AgBr is a highly promising plasmonic photocatalyst for sunlight-driven chemical transformations due to the compatibility of the high local electric field enhancement and sunlight harvesting efficiency.

Abstract:
It is a prerequisite for the occurrence of diffusive phase transformations that the system is in an off-equilibrium condition. The time-dependent development of the variables until equilibrium or steady-state conditions are reached can be calculated by solving the evolution equations that can be derived from the principle of maximum entropy production. These equations provide the theoretical framework for the kinetics of diffusive phase transformations. In this work, the development from sharp interface-local equilibrium (SI-LE) models to thick interface-finite mobility (TI-FM) models is reviewed and presented in the light of the above-mentioned principle. Experimental results indicate that the kinetics of diffusive solid-state phase transformations can, at least in certain ranges of composition and temperature, be modeled in a satisfactory manner by the TI-FM approach only.

L'última dècada ha estat testimoni del desenvolupament dramàtic de la catàlisi de fotògrafs de llum visible, s'han descobert algunes de les transformacions no reconegudes anteriorment i es van iniciar en condicions excepcionalment suaus.

Desenvolupar una fixació de CO2 fotoquímic de conformació d'enllaços cap a la síntesi d'àcid fenilacético valuós amb gran complexitat molecular.

Last decade has witnessed the dramatic development of visible light photoredox catalysis, a number of previously unrecognized transformations have been nicely discovered and proceeded under exceptionally mild conditions. Applications enabled by photoredox technique have been found in organic synthesis, pharmaceuticals and material science. However, functionalization of inert chemical bonds beyond the confined ability of conventional photocatalysts still remains less explored. Considering the research interest of Martín’s group and the potential of new designed strategy to activate inert chemical bonds, together with the accommodating technique of photoredox, we successfully disclosed the following main challenge in photochemistry: To expand the visible light promoted atom transfer radical cyclization to virtually unexplored unactivated alkyl iodides. To develop a multiple bond-forming photochemical CO2 fixation towards the synthesis of valuable phenylacetic acid with high molecular complexity. To unlock new concept for functionalizing native sp3 C-H bonds with the synergy of diaryl ketone and nickel catalyst.

Abstract:
Bismuth-containing semiconducting materials were used as visible light absorbing heterogeneous photocatalysts for selective chemical transformations. The work demonstrates the importance of kinetic control in achieving selectivity; either through photocatalyst inhibition or through the presence of reagents capable of fast reactions with known intermediates. Bismuth oxide (β-Bi2O3), bismuth ferrite (BiFeO3), bismuth tungstate microflowers (Bi2WO6) and bismuth vanadate nanoparticles (nan-BiVO4) were synthesised and characterised by PXRD, SEM, DRUVS and BET. The bismuth-containing oxides were compared as photocatalysts for the aerobic oxidation of benzyl alcohol. The highest benzyl alcohol conversion (88%) and benzaldehyde selectivity (95%) was achieved with the use of nan-BiVO4. Further modifications to nan-BiVO4 resulted in materials that were less active for selective benzyl alcohol oxidation than unmodified nan-BiVO4. Further study of nan-BiVO4 as a heterogeneous photocatalysts for the selective oxidation of para-substituted benzyl alcohols was carried out. It was found that alcohol conversions and aldehyde selectivities were affected by by-product inhibition. The addition of 1 mol% 4-methoxybenzoic acid significantly reduced 4-methoxybenzyl alcohol conversion (to 49%). Isotopically labelled benzyl alcohols were used to show that α C-H bond cleavage was not rate limiting. However, changes in charge carrier lifetimes observed using TRPLS suggested that the charge carriers associated to the lifetimes observed were relevant to benzyl alcohol oxidation. Bismuth-containing semiconductors were also investigated as trifluoromethylation heterogeneous photocatalysts. Nan-BiVO4 was capable of oxytrifluoromethylation of styrene via the reduction of Umemoto’s reagents. The highly selective reaction produced the corresponding trifluoromethylated ketone in an 88% yield. Platinised bismuth tungstate (0.15-Pt-Bi2WO6) was found to give high conversions and product selectivities for the formation of Photo-Giese products (phenylacetic acid conversion = 99%, Photo-Giese product selectivity = 94%). Several coupling products were synthesised from different carboxylic acids and electron deficient alkenes. Competitive adsorption from by-products inhibition had an impact on acid conversions and Photo-Giese product selectivities.

Abstract:
The drive for a sustainable society and a circular economy has motivated researchers around the globe to turn to the transformation of renewable raw materials like biomass into value-added products that are akin or superior to their fossil counterparts. Among these biomass raw materials, cocoa pod husks (CPH) which is the non-edible portion of cocoa (ca. 70–75% weight of the while cocoa fruit) remains a promising bio-resource raw material for the production high-value added chemicals but yet largely underexploited. Currently, the most popular applications of CPH involves its use as low-value application products such as animal feed, raw material for soap making, and activated carbon. However, the rich source of lignocellulosic content, pectin, and phenolic compounds of CPH means it could be used as raw materials for the production industrially relevant platform chemicals with high potential in the agrochemicals, pharmaceutical, and food industries, if efficient transformations routes are developed by scientists. In this chapter, we will shed light on some of the works related to the transformation of CPH into various value-added products. An economic evaluation of the transformation of cocoa pod husk into relevant chemicals and products is also discussed.

Abstract:
Sunlight can be used effectively to drive photochemical transformations in a sustainable fashion. Historically, photochemistry has been a solar research area and experiments were routinely conducted on the roof tops of chemical institutes following the ‘flask in the sun’ approach. Once powerful and reliable artificial light sources were developed, photochemistry moved inside and became a successful, but somehow neglected research area. Due to the high energy demands of technical lamps, industrial applications of photochemistry remained limited to the synthesis of certain fine chemicals. To overcome these energy needs, sunlight has recently been rediscovered as a ‘free’ energy and light source. Modern solar concentrators enable an acceleration of photochemical processes and an up-scaling to technical production. After a brief introduction to the history and present challenges of photochemistry, this chapter summarizes the most important solar reactor types and provides examples of their adaptation in preparative solar syntheses. These highlights clearly demonstrate that the solar manufacturing of fine chemicals is technically feasible and environmentally sustainable. It is hoped that further research into this truly enlightening technology will lead to industrial applications in the foreseeable future.

Abstract:
Each square metre of the Earth receives up to 1 kW of solar radiation, with the exact intensity depending on latitude, season, time of day, and weather. A significant amount of this energy is harnessed by the almost magical process we know as ‘photosynthesis’ in which water and carbon dioxide are combined to form carbohydrates. Thus, from the air and driven by sunlight, vegetation plucks vegetation. That new vegetation is at the start of the food chain, for its metabolism is used to forge protein and, in our brains, drive imagination. There is probably no more important chemical reaction on Earth. A large proportion of solar radiation is absorbed by the atmosphere. Ozone and oxygen molecules absorb a lot of ultraviolet radiation, and carbon dioxide and water molecules absorb some of the infrared radiation. As a result, plants, algae, and some species of bacteria have to make do with what gets through and evolved apparatus that captures principally visible radiation. The early forms of these organisms stumbled into a way to use the energy of visible radiation, which arrives in the packets we call photons, to extract hydrogen atoms from water molecules and use them and carbon dioxide to build carbohydrate molecules, which include sugars, cellulose, and starch. The oxygen left over from splitting up water for its hydrogen went to waste. Most of the oxygen currently in the atmosphere has been generated and is maintained by photosynthesis since Nature first stumbled on the process about 2 billion years ago and thereby caused the first great pollution. That pollution, in Nature’s characteristically careless and wholly thoughtless and unplanned way, was to turn out to be to our great advantage. Photosynthesis begins in the organelle (a component of a cell) known as a ‘chloroplast’, so you need to poke around inside one if you are to understand what is going on. I shall focus on the light harvesting and the accompanying ‘light reactions’. What follows them, the so called ‘dark reactions’ in which the captured energy is put to use to string CO2 molecules together into carbohydrates, is controlled in a highly complex way by enzymes.

Abstract:
It seems inescapable that at some point primitive cells incorporated chemical reactions related to what we now call metabolism. In all life today, metabolic reactions are driven by sources of chemical or photochemical energy, and each step is catalyzed by enzymes and regulated by feedback systems. There have been multiple proposals for the kinds of reactions that could have been incorporated into early life, but so far there is little consensus about a plausible way for metabolism to begin. This chapter will briefly review the main ideas that are familiar to chemists as solution chemistry but then ask a new question from the epigraph: how can reactions in bulk aqueous solutions be captured in membranous compartments? This question is still virtually unexplored, but I can offer some ideas in the hope of guiding potentially fruitful approaches. Because metabolism is such a complex process, it is helpful to use bullet points to help clarify the discussion. The first is a list of questions that guide the discussion, the second is list of facts to keep in mind, and the third is a list of assumptions that introduce the argument. Questions to be addressed: What are the primary metabolic reactions used by life today? What reactions can occur in prebiotic conditions that are related to metabolism? How can potential nutrient solutes cross membranes in order to support metabolism? How could metabolic systems become incorporated into primitive cellular life? Metabolism can be defined as the activity of catalyzed networks of intracellular chemical reactions that alter nutrient compounds available in the environment into a variety of compounds that are used by living systems. Most of the reactions are energetically downhill, so there is an intimate association between the energy sources available to life and the kinds of reactions that can occur. Here is a summary of energy sources used by life today: Light is by far the most abundant energy source, totaling 1360 watts per square meter as infrared and visible wavelengths. Chemical energy in the form of reduced carbon compounds is made available by photosynthesis.

Abstract:
On the road transportation sector, considering its deep involvement with many social expectations, assumed such proportions to become one of the major source of air pollution, mainly in urban highly congested areas. The use of reciprocating internal combustion engines (ICE) dominates the sector and the environmental dimension of the problem is under a strong attention of Governments. European Community, for instance, through sequences of regulations (EURO) reduced the emission allowed of primary pollutants; more recently, the Community added limits to climate-altering gases which directly refer to fuel consumption reduction. These limits today appear the new driver of the future engine and vehicle technological evolution. Similar efforts are under commitment by other developed countries (USA, Japan, etc,…) as well as also by the other Countries whose economic importance will dominate the markets in a very near future (BRICS Countries). The need to fulfill these issues and to keep the traditional engine expectations (torque, speed, fun to drive, etc..) triggered, especially in recent decades, a virtuous cycle whose result will be a new engine and vehicle era. The evolution till had today has been driven by the EURO limits and it demonstrated surprisingly that emission reduction and engine performances can be matched without compromises in both sides. Today, adding severe limits on equivalent CO2, emissions, it appears very difficult to predict how future engines (and vehicles) will be improved; new technologies are entering to further improve the traditional thermal powertrain but the way to a massive and more convinced electrification seems to be definitely opened. The two aspects will match in the sector of energy recovery which appears one of the most powerful tools for fuel consumption saving and CO2 reduction. When the recovery is done on exhaust gases it has an additional interest, having a moderate cost per unit of CO2 saved. The potentiality of this recovery is huge: 30%–35% of the chemical energy provided by the fuel is lost with the flue gases. For different reasons engines for passengers cars or goods transportation (light and heavy unit engines) as well those used for electricity generation (gen-set) are interested to this recovery: the first sector for the CO2 reduction, the second for the increasing value of electrical energy on the market. This wide interest is increasing the probability to have in a near future a reliable technology, being different actors pushing in this direction. In recent years the literature focused the attention to this recovery through a working fluid (organic type) on which the thermal energy is recovered by increasing its enthalpy. Thanks to a sequence of thermodynamic transformations (Rankine or Hirn cycle), mechanical work is produced. Both concept (Organic working fluid used and Rankine Cycle) are addressed as ORC technology. This overall technology has an evident complexity and doesn’t match with the need to keep reduced costs: it needs an energy recovery system at the gas side, an expander, a condenser and a pump. The space required by these components represents a limiting aspect. The variation of the flow rate and temperature of the gas (typical in ICE), as well as that at the condenser, represents additional critical aspect and call for suitable control strategies not yet exploited. In this paper the Authors studied an energy recovery method integrated with the turbocharging system, which does not require a working fluid making the recovery directly on the gas leaving the cylinders. Considering that the enthalpy drop across the turbine is usually higher than that requested by the compressor to boost the intake air, the concept was to consider an additional turbine which operates in parallel to the existing one. Room for recovery is guaranteed if one considers that a correct matching between turbine and compressor is actually done bypassing part of the exhaust gas from the turbine (waste gate) or using a variable geometry turbine (VGT) which, in any case, represents an energy loss. An additional positive feature is that this recovery does not impact on engine performances and the main components which realizes the recovery (valves & turbine) are technologically proven. In order to evaluate the potentiality of such recovery, the Authors developed a theoretical activity which represents the matching between turbocharger and engine. Thanks to an experimental characterization done on an IVECO F1C 16v JTD engine, an overall virtual platform was set up. The result produced a very satisfactory representation of the cited engine in terms of mechanical engine performances, relevant engine flow rates, pressures and temperatures. The ECU functions were represented too, such as boost pressure, EGR rates, rack control of VGT, etc… Two new direct recovery configurations have been conceived and implemented in the engine virtual platform.
