Hybrid multi-chamber system for enhanced removal of boron during water treatment/desalination without chemical usage

The efficiency of boron removal during water treatment and desalination is insufficient to meet the water quality standard set by the World Health Organization. Boron can exist in its two natural forms in water, depending on the water pH. At low and high pH, boron tends to exist as boric acid and borate ion, which are neutral and negatively charged, respectively. In this study, we developed a multi-chamber boron control system. For the control group (nanofiltration (NF) and reverse osmosis (RO)), the pH was controlled to enhance the boron removal efficiency. As expected, the boron removal efficiency at pH 11 (RO: 95–98%, NF: 91%) was higher than that at pH 8 (RO: 85–87%, NF: 80%). Additionally, activated carbon was introduced in the developed system (forward osmosis-NF/RO hybrid processes within the draw-solution chamber). Powdered activated carbon was more effective than granulated activated carbon in adsorbing boron molecules, with the maximum adsorption capacities (qm) of the former and latter being 2.33 and 1.33 mg g−1, respectively. A simple economic analysis was performed to determine the applicability of the multi-chamber boron control system for the economical production of high-quality water with minimal boron concentration. The unit cost of the multi-chamber boron control system (0.26 USD ton−1) was significantly lower than that associated with single NF and RO processes (0.64–1.62 USD ton−1). The multi-chamber boron control system thus represents an economical alternative that can achieve a higher product water quality compared with existing processes.

Morphological Control of Functional TiO2 Films on Magnetic Nanoparticle’s Surface by Utilizing the Boric Acid-Containing Solutions

In recent years, various functional materials are used for electronic devices such as the smartphones and conductive materials. For the further expansion of these material’s usability and usage range, it is important to achieve the highly functionalized material’s manufacturing processes compatible with “green” processes. From this point of view, the development of a sustainable functional material synthesis method that achieves both high performance and reduced the environmental load has been required.As one of such functional materials, Kishimoto1)et al. reported the synthesis and application of colored magnetic toners powders by using the buffer solution of pH 7-12 as a reaction field. In their methods, metallic iron particles coated with a homogeneous nanometer ranged TiO2 films are synthesized, and their color can be freely controlled by controlling the thickness of their films because of the interference effect.However, it is also known that not only the homogeneous core-shell materials but also the plate-like or island-like structures can be sometimes formed on the core surface. Needless to say, contamination of these lowering the property of the functional materials. Conversely, if we can elucidate the formation mechanism of these films and can achieve the selectively formation of various structured films, new functional materials can be synthesized.Therefore, in this study, TiO2 film-coated particles with various morphologies such as plate-like and dot island-like films are tried to synthesized, through the elucidation of the interaction between the surface condition and reaction solution.Carbonyl iron powder (BASF EM grade, median diameter: 4-5 μm), and Clark& Lubs buffer solution (H3BO3-KCl-NaOHaq, pH 9, 0.4 M) were used. Tetra-isopropoxy titanium (C14H28O4Ti), hydrogen peroxide water, and ammonia water were used as the titanium oxide film raw materials in the subsequent film coating step. The temperature was optimized and film coating was performed so that the peroxotitanium bonds to the substrate surface.Boric acid buffer solution after suspended the carbonyl iron particles were analyzed by XPS (XPS K-Alpha, Thermo Fisher Scientific, USA), and it showed a tendency to be significantly oxidized as compared to the particles before suspension. Waveform separation of the XPS spectrum of the O1s peak indicated that these peaks consisted by the oxygen atoms in the OH- and Fe2O3 species. ESI-TOF-MS (Bruker Dltonics; microTOFII) analysis results of the solution obtained after contacting the buffer solution and metallic iron particles shows that borate ions tended to decrease after the reaction. Thus, by controlling the relationship between the iron surface, boric acid, and the buffer solution in the solution, surface oxidation condition of the iron substance particles affected the formation of the subsequent TiO2 coating reaction. Details of other results will be present in our presentation.1) WO/2003/031683, POWDER COATED WITH TITANIA FILM AND METHOD FOR PRODUCTION THEREOF.2）G.

FRACTURING LIQUID DESIGN AND ECONOMIC ANALYSIS FOR LOW PERMEABILITY AND HIGH TEMPERATURE

Mirabelle 01 M01 well is a developed-stage well which has undergone drilling since February 2020 until May 3th 2020. It has 13000 ft depth and dominated with sandstone layers and some shaly inserts. This well is a high temperature (300 F), low permeability (0.5-5 mD) and porosity well which casues hydraulic fracturing should be done in this well. Aim: to carry out fluid fracturing design analysis by considering additional materials and economics. The perforation in this well divided into 2 perforations, first perforation has been 297 ft long and located at 12143 ft-12440 ft of well depth. The second perforation has been 45 ft in length and is located at 12,730 ft-12,685 ft of well depth. Payzone of this well is dominated by sandstone which is determined from the low gamma ray data. This Mirabelle 01 M01 well has high resistivity due to the resistivity log. Water mix used for the formation is a neutral water mix but still has several negative ions with corrosive properties such as SO42- and Cl-. Acid inhibitors are needed to remove these ions and prevent corrosive to be happened. Scale inhibitors are also needed to be added to prevent scale formation caused by Mg2+ ions which are contained in the mix water. From the average pressure calculation, the closure pressure was found about 7914.67 psi. The young modulus found from 8-10 Mpsi which indicates that the formation has high stiffness. The base of the fracturing fluid used is low price water-base fluid with guar gum polymer which can produce hydroxypropilguar (HPG) that don't ruin the formation even if the formation is in the high temperature. Borate ions are used to be crosslinker agents that binds metal ions with polymers. To split polymers molecules, sodium salt from the peroxydisulphate is used to be the gel breaker.

Bio‐Inspired Interfacial Engineering of MXene Fibers Toward Synergistic Improvement in Mechanical Strength and Electrochemical Performance

AbstractHigh‐performance fibrous materials urgently desired for fabricating energy storage devices to power wearable textile electronics are expected excellent mechanical properties, improved output capacitance, and rapid charge/discharge capability; nevertheless, their contradictory requirements in material design impose immense challenges. Inspired by the robust structure of higher plants that evolve over millions of years, herein, an interfacial engineering strategy is proposed for synergizing the mechanical strength and electrochemical performance of Ti3C2TX MXene fibers by selecting aramid (Kevlar) nanofibers and borate ions (B) as the enhancers. The intercalation of Kevlar nanofibers endows the nascent wet‐spun MXene gel fibers with a high stretchable ratio through physical interaction (hydrogen bonds), greatly aligning the orientation of MXene nanosheets. B‐cross‐links introduce covalent bonds between MXene nanosheets, which together with hydrogen bonds significantly enhance fiber strength. More importantly, optimal ion transport kinetics is achieved by synergizing the inverse impacts of Kevlar nanofibers and B‐cross‐link on interlayer spacing, guaranteeing excellent electrochemical performances. Benefiting from their excellent mechanical, electrical, and electrochemical performances, borate (B)‐cross‐linked MXene/Kevlar fibers (MKB) are simultaneously adopted as fibrous electrodes and receiving antennae for asymmetric supercapacitors with wireless charging functions. The proposed strategy provides an avenue for designing high‐performance functional fibers for future wearable applications.

Effect of borate, fluoride and strontium ions on biomimetic nucleation of calcium phosphate studied using solid-state nuclear magnetic resonance and X-ray diffraction

ObjectivesApatite minerals can have various anions and cations in their crystal structure in addition to phosphate ion (PO₄³⁻) and calcium ion (Ca2+). The aim of this study is to investigate effects of the borate, fluoride and strontium ions on biomimetic nucleation of calcium phosphate. MethodsNano-crystalline hydroxyapatite (H-Ap) was obtained from a supersaturated buffered solution containing 4.12 mM HPO42- and 5.88 mM Ca2+ (H-Ap). Four additives were used in solid solution methods: (i) 0.588 mM F- (F-Ap), (ii) 5.88 mM Sr2+ (Sr-Ap), (iii) 4.12 mM BO33- (BO3-Ap), and (iv) a surface pre-reacted glass ionomer (S-PRG) filler eluate that contained 0.17 mM Sr2+, 0.588 mM F-, 11.1 mM BO33-- (SPRG-Ap). Apatite crystallization was investigated using a solid-state magic-angle spinning NMR spectroscopy and X-ray diffraction (XRD) with the Rietveld analysis. ResultsA 2D 1H–31P heteronuclear-correlation NMR showed F- ion incorporation in the apatite structure of the F-Ap and SPRG-Ap. The peaks on the 31P axis of the F-Ap, Sr-Ap, and BO3-Ap were different from that of the H-Ap, and the full width at half maximum increased in the following order: H-Ap∼F-Ap∼BO3-Ap< SPRG-Ap< Sr-Ap, suggesting the incorporation of the F-, Sr2+ and BO33-. The incorporation of F and BO3 was further confirmed by 19F and 11B NMR. The XRD revealed that Sr2+ was preferentially incorporated into the CaII site. SignificanceThe F-, Sr2+ and BO33-ions might be involved in modifying the crystallization of apatite precipitation, producing a variety of apatite. S-PRG filler that release these ions may have an effect on remineralization, i.e., the reformation of apatite lost due to caries.

The thermoplastic polyurethane coated-LZH nanohybrids as a strategy for epoxy resin flame retardancy

Over traditional flame retardants, the hybrid material technology of flame retardant combines separate constituents into an entirety, demonstrating the benefit of the simultaneous development in polymer flame retardant. Zinc-layered hydroxide, borate, and thermoplastic polyurethane were used to create LZH/B/TU, a new organic-inorganic composite flame retardant. The structure of LZH, LZH/B, and LZH/B/TU was studied after synthesis with analysis spectroscopy. The borate ion was effectively intercalated into the interlayer space of the LZH, according to the XRD and FTIR studies. Using EDS analysis, the chemical makeup of the materials was assessed. The morphology of the synthesized product was identified using FESEM. The dynamic mechanical thermal (DMT) properties of the optimum sample were evaluated with DMTA analysis. The fire risk of epoxy resin was considerably reduced by using a small amount of LZH/B/TU. According to the flammability test and plate temperature experiment, LZH/B/TU with 1% w/w led to the creation of the char layer’s capacity to insulate heat with strong thermal resistance, resulting in dramatically reduced fire hazards.

High resistivity free-standing crosslinked graphene oxide substrates: hopping conduction mechanism and application to recyclable electronics

Graphene oxide (GO) is an oxidized derivative of graphene that can be formed into free-standing wafers by aqueous processing methods. We propose GO as a potential alternative printed electronic substrate material to mitigate the waste electronic and electrical equipment problem. By dissolving these substrates in water, GO permits the mechanical separation and recovery of discrete components from defunct circuits, thus closing the life cycle of printed circuits. In this work we measure the anisotropic, frequency dependent resistivity of free-standing GO wafers under DC and AC (f = 0.1 Hz–500 kHz) excitation and in varying relative humidity (RH) conditions. Unmodified GO and GO crosslinked with calcium ions, borate ions, and glutaraldehyde were characterized. AC resistivity measurements reveal charge transport in free-standing GO occurs by several distinct hopping conduction mechanisms that are sensitive to the crosslinking formulation. GO crosslinked with calcium ions exhibits the highest DC resistivity, 4.6 × 105 Ωm and 2.6 × 104 Ωm, for out-of-plane and in-plane directions, respectively, at 17% RH. Both AC and DC resistivities decrease with increasing RH. We demonstrate that GO wafers can be used as dielectric substrates in the construction of simple electronic circuits with discrete electronic components. Finally, we present a proof-of-concept for electrical trace and component recovery via disassembly of GO wafers in water.

Highly Stretchable, Self-Healing, Injectable and pH Responsive Hydrogel from Multiple Hydrogen Bonding and Boron-Carbohydrate Interactions.

A simple and cost-effective method for the fabrication of a safe, dual-responsive, highly stretchable, self-healing and injectable hydrogel is reported based on a combination of dynamic boronate ester bonds and hydrogen bonding interactions. The mechanical properties of the hydrogel are tunable by adjusting the molar ratios between sugar moieties on the polymer and borax. It was remarkable to note that the 2:1 ratio of sugar and borate ion significantly improves the mechanical strength of the hydrogel. The injectability, self-healing and stretchability properties of the hydrogel were also examined. In addition, the impact of the variation of the pH and the addition of free sugar responsiveness of the hydrogel was studied. High MRC-5 cell viability was noticed by the 3D live/dead assay after 24 h cell culture within the hydrogel scaffold. Hence, the developed hydrogels have desirable features that warrant their applications for drug delivery, scaffolds for cell and tissue engineering.

Understanding the boron rejection of cation intercalated multilayered graphene oxide (GO) membrane in reverse osmosis (RO) process: A molecular dynamics study

Cation-intercalated graphene oxide (GO) membrane has emerged as a promising candidate for desalination applications as reverse osmosis (RO) membrane. This study constructs GO membranes with different cations (K+ or Mg2+) and investigates the potential of these membranes in boron removal via nonequilibrium molecular dynamics simulations. In the aquatic environment, boron can exist in the form of boric acid or borate ion, depending on the pH of the solution. As a result, this study considers two forms of boron. This study reveals that the GO membranes effectively reject negatively charged borate ions due to their bigger hydration shell and stronger electrostatic repulsion with the membrane than neutral boric acid molecules. Moreover, K+ ion intercalated GO membranes showed higher boron rejection than Mg2+ ion intercalated GO membranes owing to weaker electrostatic attraction of K+ ions with the boric acid (or borate ions). Additionally, a summary of the effects of oxygen-containing functional groups of the GO membrane on boron rejection is provided. Since the hydroxyl and epoxy functional groups interact with boric acid molecules more strongly, these molecules are prevented from permeating through the membrane. On the other hand, the permeation rate of borate ions declines because of their stronger interactions with the carboxyl functional groups. Furthermore, Mg2+ ion intercalated GO membranes exhibited higher water permeance, excellent Na+ rejection, and poor Cl− rejection compared to K+ ion intercalated GO membranes.

CoNi hydroxides functionalized by borate ions with loose porous structure for the boosting of supercapacitor performance

Developing low-cost and highly efficient electrode is essential for energy storage and conversion device. Herein, CoNi hydroxide nanosheets functionalized by borate ions (denoted as CoNiB) are fabricated via a convenient wet chemical process and subsequent hydrothermal boronization reaction. It is observed that rapid generation of hydrogen in the boronization process favors the formation of nanosheets. Moreover, hydrogen as a gas template is conductive to the formation of 3D loose porous structure which not only facilitates electrolyte penetration, but also exposes more active sites and accelerates the transport of ions and electrons. Resulting from the unique hierarchical microstructure, the optimized CoNi(1:1)B electrode delivers a high specific capacity of 283.25 mAh/g at 1 A g−1 as well as good rate capability (259.38 mAh/g at 20 A g−1) and stability. Besides, the assembled asymmetric supercapacitor (ASC) device with CoNi(1:1)B as positive electrode and activated carbon as negative electrode displays an outstanding energy density of 64.7 Wh kg−1 at 814.7 W·kg−1 with good cyclability (93 % after 15,000 cycles), verifying the great application potential of CoNi(1:1)B in practice.

Mixed Rare-Earth Chalcogenide Borate Eu9–xRExMgS2B20O41 (RE = Sm, Gd) Featuring a 3D {[B20O41]22–}∞ Framework Connected by [B6O9(O0.5)6]6– and [B7O13(O0.5)3]8– Clusters

Rare-earth (RE) chalcogenide borates are very rarely discovered in view of the difficulties in synthesis though they have demonstrated attractive physical performances. Here, the first mixed RE chalcogenide borates Eu5.4Sm3.6MgS2B20O41 (1) and Eu3Gd6MgS2B20O41 (2) are synthesized by combining RE, sulfur, and borate ions into one structure. They crystallize in the centrosymmetric hexagonal space group P63/m, and their 3D honeycomb-like {[B20O41]22-}∞ open frameworks are built by [B6O9(O0.5)6]6- and [B7O13(O0.5)3]8- polyanionic clusters and consolidated by Mg2+ ions; both of which are formed by BO4 tetrahedra and BO3 planar triangles. The coordination modes of RE ions are rare REO6S2 bicapped trigonal prisms and REO8S irregular polyhedra, and their band gaps are determined to be 2.25 and 2.22 eV, respectively. They exhibit antiferromagnetic interactions and distinct photocurrent responses. The corresponding theoretical calculations are also performed. The study of 1 and 2 perhaps stimulates interest in exploring new functional RE chalcogenide borates.

Boron adsorption in clay minerals: Implications for martian groundwater chemistry and boron on Mars

Boron has been detected on Mars in calcium-sulfate veins found within clay mineral rich rocks on Mars by the Mars Science Laboratory (MSL) Curiosity rover using Laser Induced Breakdown Spectroscopy (LIBS) analysis. Borates play a vital role in stabilizing ribose on Earth and has been suggested as a key requirement for life. Borate ions readily adsorb to phyllosilicate clay minerals. The discovery of boron on Mars in proximity to phyllosilicate-bearing bedrock may have strong implications for potential past prebiotic conditions on Mars. In this study we generated a suite of clay minerals with adsorbed borate, including both typical terrestrial clay minerals (montmorillonite) and Mars-analog clay minerals (nontronite, saponite, griffithite), to understand controls on borate adsorption and to analyze with LIBS to compare with MSL data. Clay minerals were subjected to mineralogical and chemical analysis before and after adsorption. Adsorption analysis revealed that the Mars analog clay minerals adsorbed less boron than terrestrial counterparts, but within comparable amounts to those detected on Mars and in meteorites. Post-adsorption analysis by X-ray diffraction (XRD) revealed slight changes in the interlayer spacing of many of the clay minerals. Based on the adsorption analysis of the Mars-analog clay minerals, phyllosilicate-bearing bedrock in Gale crater may contain up to 90-110 ppm B. A series of borate-enriched samples were created for analysis of LIBS spectra from ChemCam on the Curiosity rover and SuperCam on the Perseverance Rover. The results of this study may provide insight into martian groundwater geochemistry processes and the mobility of a key molecule connected with life.

Multiple-Ion Releasing Bioactive Surface Pre-Reacted Glass-Ionomer (S-PRG) Filler: Innovative Technology for Dental Treatment and Care

Surface Pre-Reacted Glass-ionomer (S-PRG) filler, which releases strontium (Sr2+), borate (BO33-), fluoride (F-), sodium (Na+), silicate (SiO32-), and aluminum (Al3+) ions at high concentrations, is a unique glass filler that are utilized in dentistry. Because of its multiple-ion releasing characteristics, S-PRG filler exhibits several bioactivities such as tooth strengthening, acid neutralization, promotion of mineralization, inhibition of bacteria and fungi, inhibition of matrix metalloproteinases, and enhancement of cell activity. Therefore, S-PRG filler per se and S-PRG filler-containing materials have the potential to be beneficial for various dental treatments and care. Those include restorative treatment, caries prevention/management, vital pulp therapy, endodontic treatment, prevention/treatment of periodontal disease, prevention of denture stomatitis, and perforation repair/root end filling. This review summarizes bioactive functions exhibited by S-PRG filler and its possible contribution to oral health.

Boron isotope fractionation between B(OH)3 and B(OH)4− in aqueous solution: A theoretical investigation beyond the harmonic and Born−Oppenheimer approximations

Boron isotope fractionation between boric acid and borate ion in aqueous solution (hereafter, α3–4) is a key coefficient for reconstructing paleo-pH and paleo-pCO2 records, and a valuable parameter for understanding boron isotope geochemistry related to mineral-water interactions. Although boron isotopes have wide geologic application, the effect of temperature and ion pairing on boron isotope fractionation is poorly described. Moreover, conventional density functional theory (DFT) calculations do not provide an accurate estimate of the boron isotope fractionation factor. Here, we provide a new strategy to accurately calculate α3–4 values in aqueous solution by evaluating harmonic frequencies, higher-order energy terms, and solvation effects. Using benchmark coupled cluster (CCSD(T)) calculations, our 25 °C results for α3–4 ranges from 1.0259 to 1.0275, which is in good agreement with recent experimental data. Solvation effects reduced the α3–4 value by ∼6‰, while high-order corrections raised the α3–4 value by ∼2‰. Our calculations evaluating the effect of aqueous ion pairs suggest that the α3–4 values in seawater and pure water should be almost identical. Our results provide a reasonable estimation of the partition function ratios of dissolved boron species, which will benefit studies of boron isotope fractionation in aqueous environments.

Ethylenediamine-graphene oxide impregnated thin film nanocomposite membrane for the enhanced boron separation from seawater

The separation of toxic boron from seawater using nanofiltration (NF) membrane technology is challenging due to the neutral charge associated with boric acid at seawater pH. In this study, the ethylenediamine functionalized Graphene oxide (EDA-GO) derivative is utilized as a nanofiller to coat the active top layer of the NF membrane over the polyethersulfone ultrafiltration support. The coating involved a self-assembly reaction of hydrolyzed trimesic acid (TMA) molecules facilitated by a triethylamine base. The unique hypothesis for coating enabled the –NH2 of EDA-GO to interact with the –COOH of TMA via hydrogen bonding interactions. The rejection shown by the M-0.05 membrane with 0.05wt% loading of EDA-GO towards MgSO4, Na2SO4, and NaCl was &gt;98%, &gt;97%, and 63%, respectively. The same membrane produced water flux in the range of 35-37 L/m2h with the modest significance of the salts on the membrane flux. The M-0.05 membrane showed significantly higher rejection towards boron (&gt;47%) with a flux of 16.7 L/m2h for the beachwell seawater feed owing to the repulsive interaction between the borate ions and -NH2 and -OH groups. The rejection and flux offered by the M-0.05 membrane towards seawater's monovalent and divalent constituents were much higher than the commercial NF-90 and NF-270.

A self-healing polyvinyl alcohol-based composite with high thermal conductivity and excellent mechanical properties

Conventional thermally conductive polymeric composites are prone to mechanical failures when deployed in dynamic environments, which results in loss of functionality and reduced service life. Herein, self-healing thermally conductive composites are fabricated by dispersing polydopamine (PDA) modified boron nitride (BN) and borate ions into polyvinyl alcohol (PVA) matrix. Due to the decreased thermal interface resistance and formation of thermal conduction channels, the 13 vol% BN-PDA/PVA composite endows an enhancement of 562% in thermal conductivity (1.007 W/mK) comparing with pure PVA (0.152 W/mK). In addition, the hydrogen bonds between BN-PDA and PVA chains and the borate bonds in dynamic borax/PVA networks impart a high self-healing efficiency of more than 80% and excellent mechanical properties in BN-PDA/PVA composites. This study provides a straightforward method for the preparation of thermal interface materials with fast recovery and long service life for next generation electronic packaging applications.

Ultrastrong MXene films via the synergy of intercalating small flakes and interfacial bridging

Titanium carbide MXene combines high mechanical and electrical properties and low infrared emissivity, making it of interest for flexible electromagnetic interference (EMI) shielding and thermal camouflage film materials. Conventional wisdom holds that large MXene is the preferable building block to assemble high-performance films. However, the voids in the films comprising large MXene degrade their properties. Although traditional crosslinking strategies can diminish the voids, the electron transport between MXene flakes is usually disrupted by the insulating polymer bonding agents, reducing the electrical conductivity. Here we demonstrate a sequential densification strategy to synergistically remove the voids between MXene flakes while strengthening the interlayer electron transport. Small MXene flakes were first intercalated to fill the voids between multilayer large flakes, followed by interfacial bridging of calcium ions and borate ions to eliminate the remaining voids, including those between monolayer flakes. The obtained MXene films are compact and exhibit high tensile strength (739 MPa), Young’s modulus (72.4 GPa), electrical conductivity (10,336 S cm−1), and EMI shielding capacity (71,801 dB cm2 g−1), as well as excellent oxidation resistance and thermal camouflage performance. The presented strategy provides an avenue for the high-performance assembly of other two-dimensional flakes.

Structural analysis of Eu3+ in Li2O-MO-B2O3-Eu2O3(M=Mg, Ca, Sr, Ba) glass using XANES and EXAFS

The research focuses on the structural changes, coordination and interatomic distance of Europium doped Li2O-MO-B2O3 (M = Mg, Sr) glasses. The detailed analysis was subjected to understand Eu3+ ions in lithium magnesium borate and lithium strontium borate glasses as determined by the extended X-ray absorption fine structure analysis. XANES spectra of Eu2O3 content doped in the present glasses showed Eu3+ state upon the x-ray as incident source. The metal LIII edges, and K edges are investigated concerning alkaline earth ion glasses and their interactions with local environment. In this work, europium and barium ions in lithium borate glasses are studied by LIII-edges, strontium and calcium ions in lithium borate glasses are studied by K-edges using X-ray absorption spectroscopy to reveal the relationship between alkali earth metal ions with Eu3+, Ba2+, Ca2+, and Sr2+ ion local structure. The nearest neighbors of Eu for the first shell were analyzed for Eu–O distance in Eu3+-doped glasses by EXAFS analysis and found to be in the range of 2.35–2.36 Å. Judd-Ofelt analyses were performed, and JO parameters showed Ω4> Ω2> Ω6 trend for Mg, Ca, Sr in lithium borate glasses while a Ω2> Ω4> Ω6 trend for Ba in lithium borate glasses. Radiative properties were analyzed using JO parameters to calculate stimulated emission cross-section, branching ratio, and radiative lifetime. The calculation was also taken care of with thermal correction and found that the data obtained after thermal correction shows higher values.
