High‐Efficiency Luminescent Solar Concentrators Based on Antifogging and Frost‐Resisting Fluorescent Polymers: Adding Multiple Functions for Sustained Performance

AbstractLuminescent solar concentrators (LSCs) are light‐management devices able to harvest and downshift sunlight, making it available to edge‐coupled photovoltaic cells for light‐to‐electricity conversion. When operating in real‐life outdoor scenarios, LSCs can be exposed to humid/freezing environments which may yield fogging and frosting, ultimately resulting in detrimental performance decay owing to reduced photon absorption and photon trapping efficiency within the waveguide. To address this issue, the first demonstration of an antifogging/frost‐resisting highly efficient thin‐film LSC is presented in this work, based on a tailored semi‐interpenetrating polymer network serving as the host matrix material, where the antifogging behavior is imparted by the simultaneous presence of hydrophilic and hydrophobic segments in the macromolecular structure, whereas the fluorescent response is achieved via the incorporation of a coumarin‐functionalized methacrylic monomer. By judicious selection and compositional tuning of an additional luminescent guest dopant with excellent spectral match with the fluorescent host matrix, highly efficient (≈98%) energy transfer is achieved. Optimized LSC devices exhibit external and internal photon efficiencies as high as 3.96% and 34.79%, respectively. In addition, persistent and reproducible antifogging/frost‐resisting functionality is demonstrated during aggressive aging tests under UV‐light, with preserved fluorescence emission and prolonged and sustained device efficiency.

A Novel Conductive Antibacterial Nanocomposite Hydrogel Dressing for Healing of Severely Infected Wounds.

Wound infections are serious medical complications that can endanger human health. Latest researches show that conductive composite materials may make endogenous/exogenous electrical stimulation more effective, guide/comb cell migration to the wound, and subsequently promote wound healing. To accelerate infected wound healing, a novel medical silver nanoparticle-doped conductive polymer-based hydrogel system (Ag NPs/CPH) dressing with good conductivity, biocompatibility, and mechanical and antibacterial properties was fabricated. For the hydrogel dressing, Ag NPs/CPH, polyvinyl alcohol (PVA), and gelatin were used as the host matrix materials, and phytic acid (PA) was used as the cross-linking agent to introduce conductive polyaniline into the matrix, with antibacterial Ag NPs loaded via impregnation. After a series of analyses, the material containing 5 wt% of PVA by concentration, 1.5 wt% gelatin, 600 μL of AN reactive volume, and 600 μL of PA reactive volume was chosen for Ag NPs/CPH preparation. XPS and FTIR analysis had been further used to characterize the composition of the prepared Ag NPs/CPH. The test on the swelling property showed that the hydrogels had abundant pores with good water absorption (≈140% within 12 h). They can be loaded and continuously release Ag NPs. Thus, the prepared Ag NPs/CPH showed excellent antibacterial property with increasing duration of immersion of Ag NPs. Additionally, to evaluate in vivo safety, CCK-8 experiments of HaCat, LO2 and 293T cells were treated with different concentrations of the Ag NPs/CPH hydrogel soaking solution. The experimental results showed the Ag NPs/CPH had no significant inhibitory effect on any of the cells. Finally, an innovative infection and inflammation model was designed to evaluate the prepared Ag NPs/CPH hydrogel dressing for the treatment of severely infected wounds. The results showed that even when infected with bacteria for long periods of time (more than 20 h), the proposed conductive antibacterial hydrogel could treat severely infected wounds.

Dianthracenylazatrioxa[8]circulene: Synthesis, Characterization and Application in OLEDs.

A soluble, green-blue fluorescent, π-extended azatrioxa[8]circulene was synthesized by oxidative condensation of a 3,6-dihydroxycarbazole and 1,4-anthraquinone by using benzofuran scaffolding. This is the first circulene to incorporate anthracene within its carbon framework. Solvent-dependent fluorescence and bright green electroluminescence accompanied by excimer emission are the key optical properties of this material. The presence of sliding π-stacked columns in the single crystal of dianthracenylazatrioxa[8]circulene is found to cause a very high electron-hopping rate, thus making this material a promising n-type organic semiconductor with an electron mobility predicted to be around 2.26 cm2 V-1 s-1 . The best organic light-emitting diode (OLED) device based on the dianthracenylazatrioxa[8]circulene fluorescent emitter has a brightness of around 16 000 Cd m-2 and an external quantum efficiency of 3.3 %. Quantum dot-based OLEDs were fabricated by using dianthracenylazatrioxa[8]circulene as a host matrix material.

Recent Progress of 2D Nanomaterials for Application on Microwave Absorption: A Comprehensive Study

Rapid advancements and wide spread of microwave- and RF-communication systems over the years have led to an abundant increase in electromagnetic energy radiation in our living environment. Such an increase in microwave sources is due to the development and advancement in communication techniques (mobile phones, laptops, and antennas for aeronautics or automobile) and electronic warfare in the military field (radar and satellite). Recently research efforts are focused on finding solutions to guarantee protection from electromagnetic (EM) radiations. The EM absorbing materials are used to overcome these issues to ensure public protection as well as safe military operations. Various types of EM absorbing materials comprising composite materials have been progressively developed and researched. This kind of material is developed by impeding absorbing charges (magnetic or dielectric) into a host matrix material. Recently, carbon allotropes such as graphene, MXenes, carbon nanotubes (CNTs), and carbon fibers have attracted increasing attention owing to their EMI shielding characteristics and lightweight. This work presents a comprehensive study on the recent research progress on the application of nanomaterials for electromagnetic shielding and absorption. The review will cover the microwave absorption mechanism and absorption performance using graphene, MXenes, carbon nanotubes (CNTs), carbides, and ferromagnetic metals. Overall, the review will present a timely update on the research progress of microwave absorption performance of various nanomaterials.

Controlling hydroxyl content of reduced graphene oxide for superior cathode performance of lithium sulfur batteries

Here, the hydroxyl content of reduced graphene oxide (rGO) is controlled by adjusting reduction time with l-ascorbic acid as reduction agent to study the effect on cathode performance of lithium sulfur batteries (LSBs). The results indicate that the hydroxyl content decreases from 35.8% to 17.9% with prolonging reduction time from 6 h to 48 h, and the C/O ratio increases. More importantly, it is demonstrated that the rGO with relatively low hydroxyl content within 36 h of reduction is more beneficial to enhance both the initial capacity and capacity retention as well as rate performance of LSBs, which is ascribed to the higher conductivity, stronger adsorption and relatively few reaction by-products with the decrease of hydroxyl content. However, when the reduction time is further prolonged to 48 h, the cathode performance deteriorates. As a result, rGO-36h/S electrode with the optimum hydroxyl content (19.2%) achieves an initial discharge capacity of 1340.9 mAh g−1, which still maintains 707.8 mAh g−1 over 100 cycles at 0.1C. This work may provide a guide for reducing GO when used as sulfur host material or matrix material of LSBs.

Metal-Organic Frameworks for Enzyme Immobilization: Beyond Host Matrix Materials.

Enzyme immobilization in metal–organic frameworks (MOFs) as a promising strategy is attracting the interest of scientists from different disciplines with the expansion of MOFs’ development. Different from other traditional host materials, their unique strengths of high surface areas, large yet adjustable pore sizes, functionalizable pore walls, and diverse architectures make MOFs an ideal platform to investigate hosted enzymes, which is critical to the industrial and commercial process. In addition to the protective function of MOFs, the extensive roles of MOFs in the enzyme immobilization are being well-explored by making full use of their remarkable properties like well-defined structure, high porosity, and tunable functionality. Such development shifts the focus from the exploration of immobilization strategies toward functionalization. Meanwhile, this would undoubtedly contribute to a better understanding of enzymes in regards to the structural transformation after being hosted in a confinement environment, particularly to the orientation and conformation change as well as the interplay between enzyme and matrix MOFs. In this Outlook, we target a comprehensive review of the role diversities of the host matrix MOF based on the current enzyme immobilization research, along with proposing an outlook toward the future development of this field, including the representatives of potential techniques and methodologies being capable of studying the hosted enzymes.

Inorganic and Organic Nano-Emitters for Luminescent Solar Concentrators

Generating power directly from solar radiation represents a promising opportunity towards addressing the increasing demand for clean energy, also reducing environmental impact caused by excessive carbon emissions. Luminescent solar concentrators (LSCs) are being widely studied as fluorophore-containing waveguides to harvest solar energy in combination with photovoltaic (PV) technologies, due to their low cost and straightforward synthesis by wet chemical approaches. LSCs can play an important role in the emerging building-integrated photovoltaic (BIPV) industry as they provide a low cost alternative to transparent solar cell. 1-4 Typical LSCs consist of optical waveguides doped with highly emissive fluorophores which are required to exhibit high optical efficiency and long-term stability. Among various types of luminescent particles suitable for LSCs, inorganic quantum dots (QDs) are excellent candidates because they offer several advantages, including high good quantum yield (QY), size-tunable absorption/emission, better chemical-/photo-stability and cost-effectiveness compared to traditional organic dyes.5An efficient lumiphores for LSC should meet these requirements: (a) broad light absorption (b) high photoluminescence quantum yield (PLQY), (c) large Stokes shift (absence or low overlap between absorption and emission spectra), (d)compatibility with the host matrix material and (e) low cost. By exploiting the excellent properties of QDs, such as the size-tunable absorption and emission, herein we will introduce different strategies to achieve cost-effective large-area (100cm2) LSC based on inorganic QDs.3, 6, 7 Furthermore, in order to reduce the environmental impact of such devices, it will be explored the use of carbon dots (Cdots) as organic nano-emitters for LSC. Cdots are the latest addition to the carbon nanoallotropes family and they are exclusively composed of non-toxic elements, such as nitrogen, carbon and oxygen. They can be easily synthetized in large quantities by solvothermal method. Their main advantages, compared to conventional semiconducting quantum dots (QDs), is the non-toxicity, environmental friendliness, low-cost and simple preparation using abundant carbon based feedstock.In this work different type of Cdots with different surfaces functionalization and optical features are prepared. In particular their absorption and emission spectra are tuned in the Visibile/Near infra-red range.Carefully chosen Cdots are then employed as luminophores for metal-free large-area LSC.8, 9 REFERENCES: 1.

Near-field negative electroluminescent cooling via nanoparticle doping

Modulating the photon tunneling probability is the key to control the near-field radiative heat transfer (NFRHT) between two objects. It has been found that nanoparticle doping technology can enable plentiful resonance modes which significantly adjust photon emission spectra. In this work, we theoretically analyze the performance of a near-field negative electroluminescent refrigeration (NFNELR) system consisting a Mie-metamaterial emitter and mercury cadmium telluride (MCT) receiver with spacing between them less than the thermal wavelength. The emitter consists of graphene/SiC core-shell (GSCS) nanoparticle-embedded thin film of Si deposited on bulk Si. We show that with the inclusion of GSCS nanoparticles, the thin layer of Mie-metamaterial acts like an effective medium that excites radiative heat transfer for the photons above the band gap of MCT. We analyze NFNELR performance for various bias voltages, various cryogenic temperatures, various volume fractions and various chemical potentials of GSCS nanoparticles. We also would like to emphasize that in order to improve the performance of the NFNELR system, the host matrix materials chosen are not necessarily stationary. These results provide a powerful way to rouse and regulate the NFRHT, meanwhile in turn, open up a way to explore actual development and present some guidance for optimal design of NFRHT.

Humidity-Insensitive Tissue Oxygen Tension Sensing for Wearable Devices†.

Quantification of tissue oxygen partial pressure (pO2 ) at the skin surface is crucial for diagnostic applications in burns, reconstructive surgeries, diabetic ulcers, etc. Further, current advances in wearable and communications technologies have widened the use of transcutaneous oxygen monitors (TCOM) for home care or even enhance athletic performance. For TCOM technology to find widespread use, devices must function reliably yet independently of changes in environmental conditions, humidity in particular. To this end, we have explored the incorporation of an oxygen-sensing metalloporphyrin within different host matrix materials of different compositions with the goal of overcoming the humidity sensitivity of previously explored oxygen-sensing materials. We developed a tetraethyl orthosilicate (TEOS)-based, highly breathable, oxygen-sensing metalloporphyrin polymer film which responds to changes in oxygenation independent of humidity.

Host Matrix Materials for Luminescent Solar Concentrators: Recent Achievements and Forthcoming Challenges

Luminescent solar concentrators (LSCs) have attracted increasing attention in the past few years as appealing solar energy technology for the seamless integration of photovoltaic (PV) systems into the built environment. Traditionally, research in this field has focused on two main aspects: the optimization of the device assembly, in the quest for more efficient architectures to maximize collection, transport and conversion of photons into usable electrical energy; the development of novel, highly emissive luminescent species, to ensure broad light collection and efficient photon emission. Only recently, the attention has also been directed towards the selection and development of suitable host matrix/waveguide materials with appropriate optical properties, sufficient chemical compatibility with the guest luminescent species, good processability for easy device fabrication and prolonged durability in outdoor operation. In additional to consolidated polymeric systems based on polyacrylates or polycarbonates, in recent years different examples of alternative host matrix systems have been proposed, characterized by peculiar chemical, physical and optical characteristics specifically designed to meet the stringent requirements of the LSC technology. This mini-review will focus on recent developments in the design of new host matrix materials for LSC applications. An overview of the most recent examples of novel LSC host matrices will be provided here, mainly focusing on new polymers, polymer-based organic-inorganic hybrids and multifunctional organic systems. Finally, opportunities and challenges in the field will be considered in view of the effective exploitation of the LSC technology in real application scenarios.

Thermoelectric Properties of FeSb2Te Based Ternary Skutterudites with Mo Nanoinclusions

Polycrystalline samples of FeSb2Te ternary skutterudite based compounds were prepared by the powder metallurgy method. The influence of additions of Mo nanoparticles into host-matrix compound (FeSb2Te) was investigated. Wet blending route (ultrasonication/rotavapor) was used to obtain homogeneous dispersion of the host-matrix compound with Mo nanoparticles. The nanocomposite powders FeSb2Te+x vol.% Mo (x=0, 2, 4, 6) were hot-pressed for 1hr at 500°C/70 MPa. The prepared p-type samples were characterized by measurements of their electrical conductivity, Seebeck coefficient, and thermal conductivity. SEM and EDX results revealed Mo nanoparticles mainly inside of intergrain space of the host-matrix material. Strikingly, Mo does not react with the matrix material. The presence of the Mo nanoparticles in the intergrain space appears to reduce phonon mean free path resulting in a reduction of the thermal conductivity of the studied nanocomposite materials. The extra scattering of phonons on the embedded Mo nanoparticles is responsible for about 20% increase of ZT at some of the nanocomposite samples

We report the use of an ecofriendly and recyclable CNC material as the host matrix for luminescent solar concentrator applications.

Determination of elastic moduli of composite medium containing bimaterial matrix and non-uniform inclusion concentrations

Reservoir porous rocks usually consist of more than two types of matrix materials, forming a randomly heterogeneous material. The determination of the bulk modulus of such a medium is critical to the elastic wave dispersion and attenuation. The elastic moduli for a simple matrix-inclusion model are theoretically analyzed. Most of the efforts assume a uniform inclusion concentration throughout the whole single-material matrix. However, the assumption is too strict in real-world rocks. A model is developed to estimate the moduli of a heterogeneous bimaterial skeleton, i.e., the host matrix and the patchy matrix. The elastic moduli, density, and permeability of the patchy matrix differ from those of the surrounding host matrix material. Both the matrices contain dispersed particle inclusions with different concentrations. By setting the elastic constant and density of the particles to be zero, a double-porosity medium is obtained. The bulk moduli for the whole system are derived with a multi-level effective modulus method based on Hashin’s work. The proposed model improves the elastic modulus calculation of reservoir rocks, and is used to predict the kerogen content based on the wave velocity measured in laboratory. The results show pretty good consistency between the inversed total organic carbon and the measured total organic carbon for two sets of rock samples.

Gel-Entrapped Staphylococcus aureus Bacteria as Models of Biofilm Infection Exhibit Growth in Dense Aggregates, Oxygen Limitation, Antibiotic Tolerance, and Heterogeneous Gene Expression

An experimental model that mimicked the structure and characteristics of in vivo biofilm infections, such as those occurring in the lung or in dermal wounds where no biomaterial surface is present, was developed. In these infections, microbial biofilm forms as cell aggregates interspersed in a layer of mucus or host matrix material. This structure was modeled by filling glass capillary tubes with an agarose gel that had been seeded with Staphylococcus aureus bacteria and then incubating the gel biofilm in medium for up to 30 h. Confocal microscopy showed that the bacteria formed in discrete pockets distributed throughout the gel matrix. These aggregates enlarged over time and also developed a size gradient, with the clusters being larger near the nutrient- and oxygen-supplied interface and smaller at greater depths. Bacteria entrapped in gels for 24 h grew slowly (specific growth rate, 0.06 h(-1)) and were much less susceptible to oxacillin, minocycline, or ciprofloxacin than planktonic cells. Microelectrode measurements showed that the oxygen concentration decreased with depth into the gel biofilm, falling to values less than 3% of air saturation at depths of 500 μm. An anaerobiosis-responsive green fluorescent protein reporter gene for lactate dehydrogenase was induced in the region of the gel where the measured oxygen concentrations were low, confirming biologically relevant hypoxia. These results show that the gel biofilm model captures key features of biofilm infection in mucus or compromised tissue: formation of dense, distinct aggregates, reduced specific growth rates, local hypoxia, and antibiotic tolerance.

Impulsive SRS in tetragonal t-YVO4, t-GdVO4and monoclinic m-LaVO4vanadate host-crystals for Ln3+-lasant ions

Tetragonal t-YVO4, t-GdVO4 and monoclinic m-LaVO4 are widely known as host-matrix materials for Ln3+-lasant ions in high-gain SRS-active crystals. In this study, many phonon impulsive stimulated Raman scattering (ISRS) was excited under femtosecond pumping for these materials. All of the observed χ(3)-non-linear lasing components were attributed to the vibrations of the [VO4]3− structural units of these vanadates. The article gives a short review (in table form) of all known SRS-active crystals with tetragonal zircon-type (ZrSiO4) and monazite-type (CePO4) structure and their observed χ(3)-nonlinear optical effects.

Relationship between Site Symmetry, Spin State, and Doping Concentration for Co(II) or Co(III) in β-NaYF4

Magnetic dopants provide versatile tunability of properties for transparent host matrix materials, semiconductors, and nanostructured materials. The relationship between doping concentration, site symmetry, crystal-field splitting, and spin state for Co(II) and Co(III) doped in hexagonal-phase NaYF4 crystals and nanocrystals was investigated in a spin-polarized density functional theory approach. With decreasing dopant concentrations, the geometry of the Co(II) fluoride nearest-neighbor coordination changes from approximately square pyramidal to square planar to cubic before converging to pentagonal bipyramidal coordination. A transition from low-spin to high-spin was observed, accompanying the geometry transformation from square planar to cubic, which is consistent with expectations from basic crystal-field theory. Magnetic ordering of adjacent ions was found to have little influence on this spin-transition process. For Co(III), decreasing concentration resulted in a geometry transformation from approxim...

Solid-State Solvation and Enhanced Exciton Diffusion in Doped Organic Thin Films under Mechanical Pressure.

Direct modification of exciton energy has been previously used to optimize the operation of organic optoelectronic devices. One demonstrated method for exciton energy modification is through the use of the solvent dielectric effects in doped molecular films. To gain a deeper appreciation of the underlying physical mechanisms, in this work we test the solid-state solvation effect in molecular thin films under applied external pressure. We observe that external mechanical pressure increases dipole-dipole interactions, leading to shifts in the Frenkel exciton energy and enhancement of the time-resolved spectral red shift associated with the energy-transfer-mediated exciton diffusion. Measurements are performed on host:dopant molecular thin films, which show bathochromic shifts in photoluminescence (PL) under increasing pressure. This is in agreement with a simple solvation theory model of exciton energetics with a fitting parameter based on the mechanical properties of the host matrix material. We measure no significant change in exciton lifetime with increasing pressure, consistent with unchanged aggregation in molecular films under compression. However, we do observe an increase in exciton spectral thermalization rate for compressed molecular films, indicating enhanced exciton diffusion for increased dipole-dipole interactions under pressure. The results highlight the contrast between molecular energy landscapes obtained when dipole-dipole interactions are increased by the pressure technique versus the conventional dopant concentration variation methods, which can lead to extraneous effects such as aggregation at higher doping concentrations. The present work demonstrates the use of pressure-probing techniques in studying energy disorder and exciton dynamics in amorphous molecular thin films.

Novel high-durability luminescent solar concentrators based on fluoropolymer coatings

Abstract Fluorescent polymeric coatings can find interesting applications in the field of solar energy as thin-film luminescent solar concentrators (LSCs). At present, polymers such as polycarbonate (PC) or poly(methyl-methacrylate) (PMMA) are commonly used as dye-doped host matrix materials in LSCs. However, LSC devices based on these polymers still present limited lifetimes resulting from the intrinsic poor photostability of the polymeric carrier. In the attempt to achieve high-durability LSC devices, a series of new crosslinked fluoropolymeric systems is presented in this work as potential alternative host matrix coating materials for LSC applications. The chemical, physical and morphological modifications occurring to the crosslinked fluorinated coatings when subjected to long-term UV–vis light exposure (over 1000 h of accelerated weathering) are found to correlate well with the photovoltaic response over long-term operation of functioning LSC devices. In particular, better operational stability compared to reference PMMA-based devices can be obtained with the new crosslinked fluorinated coatings by appropriate selection of crosslinking agent. In addition, the effect of radical scavengers on LSC device operational stability is also investigated and it is found that in the long-term light exposure regime (>600 h) these additives may lead to improvements in LSC device lifetime. The results of this study allow a greater understanding of structure–property relationships in crosslinked fluorinated coatings subjected to long-term weathering and provide useful guidelines for the design of high durability fluorescent coatings for light management and photovoltaics.

Novel crosslinked host matrices based on fluorinated polymers for long-term durability in thin-film luminescent solar concentrators

Polymer-based thin-film luminescent solar concentrators (LSCs) currently rely on poly(methyl-methacrylate) (PMMA) as host matrix material. However, PMMA-based LSCs still suffer from degradation due to the limited photostability of the polymer. In this work, a new crosslinked fluoropolymer-based system is presented as a potential alternative host matrix material for the fabrication of durable polymer-based LSC devices. The new host matrix system is obtained by crosslinking a functional chloro-trifluoro-ethylene-vinyl-ether copolymer with an aliphatic isocyanurate crosslinker. It is shown that efficiency values comparable to those obtained with optimized PMMA-based thin film LSC devices can be reached with the new crosslinked fluoropolymer-based LSC system. In addition, superior long-term operational stability compared to PMMA-based devices can be obtained with the new fluoropolymer-based host matrix, as evidenced by long-term continuous light exposure tests (over 500h) on operating LSC devices. The results of this work demonstrate that crosslinked fluorinated polymers represent a class of promising host matrix materials to achieve environmentally stable LSC devices.

Hemin@metal–organic framework with peroxidase-like activity and its application to glucose detection

A composite material has been successfully prepared for the first time using an amino-containing metal–organic framework (MOF) as a new type of host matrix material to anchor hemin and simulate the peptidic microenvironment of the native peroxidase. The material was characterized by XRD, SEM, EDS, FT-IR techniques and an N2 adsorption method. It exhibited peroxidase-like activity through catalytic oxidation of the peroxidase substrate 3,3,5,5-tetramethylbenzidine (TMB) in the presence of H2O2, producing a blue-colored solution. Under optimal conditions, the absorbance at 652 nm is linearly correlated with the concentration of H2O2 from 5.0 × 10−6 mol L−1 to 2.0 × 10−4 mol L−1 (R2 = 0.994). More importantly, a sensitive and selective method for glucose detection was developed using the as-prepared mimetic peroxidase as a catalyst with the help of glucose oxidase (GOx). The analytical platform for glucose detection was observed to have a linear range from 1.0 × 10−5 mol L−1 to 3.0 × 10−4 mol L−1 (R2 = 0.993). This work informs researchers of the advantages of MOFs for preparing biomimetic catalysts and extends the functionality of MOFs to biosensor applications.
