Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband SWIR luminescent materials and poor thermal stability of current Ni-activated phosphors are the ongoing challenges. Here, a blue-light-excitable (440 nm) YAlGaO:Cr,Ni phosphor with ultrawide SWIR emission centered at ∼1430 nm (FWHM ∼264 nm) is reported.

Introduction: Glomerular filtration rate (GFR) estimation equations have not been extensively validated in the Indian population. Preliminary data showed that the widely used creatinine-based Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) 2009 significantly overestimated GFR in Indians. Newer estimated GFR (eGFR) equations based on creatinine and cystatin C, omitting the race, have been recently proposed.

Diabetes mellitus is considered one of the major worldwide health emergencies of the twenty-first century. This work described development, synthesis, and characterization of new (Z)-2-(2,4-dioxothiazolidin-5-ylidene)methyl)-2-ethoxyphenyl-alkyl/aryl-sulfonates. Compounds 7j and 7m were shown to be the most potent among the newly developed (Z)-2-(2,4-dioxothiazolidin-5-ylidene)methyl)-2-ethoxyphenyl-alkyl/aryl-sulfonates after in vitro testing for α-glucosidase inhibitory activity.

Near-infrared (NIR) fluorescent agents are extensively used for biomedical imaging due to their ability for deep tissue penetration. Tetrapyrrole-based photosensitizers are promising candidates in this regard. Further, the extended conjugation of such macromolecules with chromophores can enhance their fluorescence efficiency and DNA intercalation ability.

In this paper, the production of pyrolyzed oil in lab scale plant and its possible use in variable speed diesel engine with nanoparticle and secondary fuel oxy-hydrogen gas is investigated. The pyrolyzed oil is produced from waste tires in lab scale plant, and after its distillation, it is blended with neat diesel in the proportion of 20:80 (TDF). The different testing fuels are prepared by mixing nanoparticle CeO (NP) at the concentrations 50 ppm and 100 ppm with blended fuel (named as TDF-NP50 and TDF-NP100).

Article Synopsis
  • Oral cancer is the most common type of cancer in the head and neck region, with rising incidence globally, causing significant health issues at advanced stages; early diagnosis is crucial for effective management.
  • The study focuses on the serum levels of a protein called MMP-9 as a potential predictive biomarker for oral cancer progression, analyzing its concentrations in 38 patients using blood samples.
  • Results showed that MMP-9 levels were higher in patients with advanced oral cancer stages, revealing significant correlations with clinical parameters like HDL and PTI, but no notable differences based on demographic factors.

Among all non-communicable diseases, cancer is ranked as the second most common cause of death and is rising constantly. While cancer treatments mainly include radiation therapy, chemotherapy, and surgery; chemotherapy is considered the most commonly employed and effective treatment. Most of the chemotherapeutic agents are azoles based compounds and imidazole is one such insightful azole.

Molecular catalysts offer tunable active and peripheral sites, rendering them ideal model systems to explore fundamental concepts in catalysis. However, hydrophobic designs are often regarded as detrimental for dissolution in aqueous electrolytes. Here we show that established cobalt terpyridine catalysts modified with hydrophobic perfluorinated alkyl side chains can assemble at the gas-liquid-solid interfaces on a gas diffusion electrode.

Breast cancer is one of the leading causes of death among women globally, making its diagnosis and treatment challenging. The use of nanotechnology for cancer diagnosis and treatment is an emerging area of research. To address this issue, multiwalled carbon nanotubes (MWCNTs) were ligand exchanged with butyric acid (BA) to gain hydrophilic character.

Background: Community-acquired acute kidney injury (CA-AKI) is a sudden structural damage and loss of kidney function in otherwise healthy individuals outside of hospital settings having high morbidity and mortality rates worldwide. Long-term sequelae of AKI involve an associated risk of progression to chronic kidney disease (CKD). Serum creatinine (SCr), the currently used clinical parameter for diagnosing AKI, varies greatly with age, gender, diet, and muscle mass.

The destructive assay of bulk uranium and plutonium, a cornerstone for chemical quality control and nuclear material accounting of fuel matrices, mandates robust and precise methodologies. Despite ongoing research, simultaneous, matrix independent determination of U and Pu has eluded solution owing to inherent limitations in aqueous acid medium, viz., coexistence of multiple oxidation states, coupled electrochemical reactions, smaller potential window, and requirement for multistep sample preconditioning and tedious electrode modification.

The emergence of bacterial resistance to antimicrobial agents poses a serious threat to the effectiveness of treating bacterial illnesses. A major factor contributing to antimicrobial resistance is biofilm formation, driven by quorum sensing (QS). QS suppression inhibits the QS signaling pathway, obstructing cell-to-cell communication.

The synthesis, characterization and photocatalytic hydrogen evolution reaction (HER) performance of a series of metal-organic gels (MOGs) constructed from titanium(IV)-oxo clusters and dicarboxylato linkers (benzene-1,4-dicarboxylato and 2-aminobenzene-1,4-dicarboxylato) are described. All the MOGs exhibit a microstructure comprised of metal-organic nanoparticles intertwined into a highly meso-/macroporous structure, as demonstrated by cryogenic transmission electron microscopy and gas adsorption isotherms. Comprehensive chemical characterization enabled the estimation of the complex formula for these defective materials, which exhibit low crystallinity and linker vacancies.

The hydrogen evolution and nitrite reduction reactions are key to producing green hydrogen and ammonia. Antenna-reactor nanoparticles hold promise to improve the performances of these transformations under visible-light excitation, by combining plasmonic and catalytic materials. However, current materials involve compromising either on the catalytic activity or the plasmonic enhancement and also lack control of reaction selectivity.
