A simple approach using <italic>Nelumbo nucifera</italic> seeds for synthesizing silver nanoparticles with potential antibacterial and cytotoxic activities was described.
Toward the imperative treatment of industrial wastewater containing 4-nitrophenol (4-NP) and solid waste red mud (RM), an innovative approach "Using to treat waste" is developed. Valuable element Al leached from RM first, resultant NaAlO2 solution hydrothermally converted γ-AlOOH hierarchical porous microspheres (RM HPMSs, average diameter: 2.0 μm, SBET: 77.81 m2 g−1, pore volume: 0.38 cm3 g−1) in presence urea. The subsequent mild thermal conversion results γ-Al2O3 HPMSs). Both HPMSs are...
A novel Schiff-base polydentate derivative (NNAP) was developed as a practical probe for multi-wavelength colorimetric differentiation of trace Fe<sup>2+</sup> from Fe<sup>3+</sup>.
Emerald from the deposit at Dayakou is classified as a vanadium-dominant emerald together with Lened, Muzo, Mohmand, and Eidsvoll emeralds. Although previous studies defined these V-dominant emeralds traced genesis of deposit, there has not been any systematic comparison or discrimination on deposits. The origin parental fluid crystallization process remain controversial. In this study, both major trace element signatures 34 samples are analyzed through electron microprobe analysis (EMPA)...
Pakistan's production of emeralds has been increasing in recent years, and reserves are estimated at almost 70 million carats (Jamal-ud-Din, 2014;Makki Ali, 2019).Swat Valley is known for small stones with saturated color (figure 1).Mineralogical curiosities include three-phase fluid inclusions (Gübelin, 1982) newly discovered trapiche-type (Khan, 2018).Photomicrographs Swat provided the first time this study.The history geology deposit were comprehensively reported by Arif et al. (2011)...
Abstract Apatite major and trace element chemistry is a widely used tracer of mineralization as it sensitively records the characteristics magmatic-hydrothermal system at time its crystallization. Previous studies have proposed useful indicators binary discrimination diagrams to distinguish between apatites from mineralized unmineralized rocks; however, their efficiency has been found be somewhat limited in other systems larger-scale data sets. This work applied machine learning (ML) method...
The Malysheva emerald mine (Urals, Russia) boasts a long history and extraordinary output. However, recent studies indicate that emeralds share highly similar inclusion varieties, UV-visible-near infrared (UV-Vis-NIR) spectra, compositional characteristics with other tectonic-magmatic-related (type I) from Zambia, Brazil, Ethiopia. This similarity poses challenges for determination of the emeralds’ origin. paper systematically investigates microscopy, spectroscopy, trace element chemistry...
A facile EDTA-2Na-assisted hydrothermal route is developed to synthesize hierarchical carnation-like Ca<sub>4</sub>B<sub>10</sub>O<sub>19</sub>·7H<sub>2</sub>O microspheres as high-efficiency adsorbents for heavy metal ion (Pb<sup>2+</sup>) removal from mimic wastewater.
H2O molecules in emerald channels have been extensively discussed over the past half century. Recent studies paid attention to their classification and coordination, but mostly focused on type related Na+. There are few works other types, infrared (IR) absorption bands rather controversial. This paper investigated natural emeralds from China Colombia by means of micro-Fourier transform (μ-FTIR) spectroscopy, micro-confocal Raman laser ablation-inductively coupled plasma mass spectrometry...
Synthetic rock crystals often show a typical infrared (IR) absorption band at 3585 cm−1. However, the authors recently found this in natural crystal with blue coating. The origin of IR is controversial as yet. In paper, spectra several and synthetic samples which were heated to 673 K 1073 measured after these returned room temperature. Comparing before heating, we cm−1 was induced by thermal process, indicates that cannot be used diagnostic evidence for alone. addition, LiOH bands decreased...
Correction for ‘Facile hydrothermal synthesis of hierarchical porous priceite (Ca<sub>4</sub>B<sub>10</sub>O<sub>19</sub>·7H<sub>2</sub>O) microspheres as high-efficiency adsorbents heavy metal ions removal’ by Wancheng Zhu <italic>et al.</italic>, <italic>CrystEngComm</italic>, 2019, DOI: 10.1039/c9ce01003c.
The hydroxyl of the gem-grade forsterite from Pakistan was measured by polarized spectra at room temperature to 1000 °C, showing four unambiguous absorption bands 3612, 3597, 3579, and 3566 cm−1. Here, we report angle-resolved IR spectroscopy crystal-oriented forsterite, which were heated 1 bar up °C in situ investigate hydrogen diffusion character. peak positions absorbance 3579 cm−1, 3597 cm−1 decreased linearly depending on temperature, while 3612 is stable. We discuss that dipole...
The age of globalization has brought unparalleled changes to how societies operate, affecting everything from economic systems individual identities. This transformative era necessitates a critical reevaluation human rights—a concept that, while universally proclaimed, faces diverse and complex challenges across different global contexts. In this letter, I wish explore the multifaceted nature rights in globalization, drawing upon various scholarly insights highlight pressing need for...
