The KSiF:Mn (KSFM) phosphor featuring efficient ultranarrow red emissions is an outstanding candidate for white light-emitting diode (WLED) applications. However, poor moisture resistance seriously affects its application performance. In this study, a two-step surface reconstruction strategy is proposed to dramatically enhance the moisture resistance of commercially available KSFM phosphors, involving treatment with HNbF and subsequent hydrothermal treatment.
View Article and Find Full Text PDFOxygen evolution reaction is an essential but kinetically sluggish step in many energy storage and conversion processes and therefore is in pursuit of highly efficient and stable catalysts. Although nanosized transition-metal-based oxides/hydroxides exhibit high catalytic activity toward the oxygen evolution reaction (OER), many of them suffer from low stability at an anode current density in industrial scale. Herein, by combining a rapid epitaxial formation method with dynamic bubble-templated electrodeposition, we successfully developed single crystalline NiFeCu oxide catalysts with a hierarchical porous structure.

However, the rational design of high-performing PBAs is challenging, which requires an in-depth understanding of the catalytic mechanism. Here FeMn@CoNi core-shell PBAs are employed as precursors, together with Se powders, in low-temperature pyrolysis in an argon atmosphere.

Methods: We retrospectively reviewed patients with osteochondral lesion of talus who were admitted to our hospital from April 2020 to April 2021.
Prussian blue analogs (PBAs) are considered as efficient catalysts for energy-related applications due to their porous nanoscale architectures containing finely disseminated active sites. Their catalytic capability can be greatly boosted by the rational design and construction of complex PBA hybrid nanostructures. However, present-day structure engineering inevitably involves additional etchant or procedure.

Near-infrared (NIR) pc-LED light sources have great application potential in the food industry and medical fields, which stimulate the extensive exploration of NIR phosphors. In this work, broad-band NIR-emitting InBO:Cr phosphors with submicron size and spherical morphology are successfully synthesized via the molten salt method.

Rationale: Angiotensin receptor blocker (ARB) can increase serum creatinine or potassium levels in patients with renal insufficiency, renal artery stenosis, heart failure or hypovolemia, but hardly cause severe kidney injury in patients without any risk factors. A case of severe acute interstitial nephritis (AIN) induced by valsartan was reported here.
Patient Concerns: A 62-year-old female with nausea for 1 month and acute deterioration of kidney function for 2 weeks was admitted.
NIR-emitting YAl(BO):Cr/Yb (YAB:Cr/Yb) and NaScSiO:Cr (BSSO:Cr) phosphors were demonstrated as luminescent converters for broadband NIR phosphor-converted LEDs (pc-LEDs). YAB:Cr/Yb phosphors show emissions in 670-800 nm (Cr emission) and 950-1050 nm (Yb emission) upon excitation at 450 nm. In the BSSO host, Cr ions occupy Sc sites with relatively weak crystal field, and thus a broadband Cr emission at longer wavelengths of 750-950 nm is found for BSSO:Cr phosphors.

In this study, we tried to profile whether miRNA expression differences exist after human umbilical cord mesenchymal stem cells (hUCMSCs) treatment in PF rats and investigate the possible role of miR-153-3p involved in anti-EMT process. We randomly assigned 34 rats into three groups: control group (Group Control), MGO-induced PF rats (Group MGO) and hUCMSCs-treated rats (Group MGO + hUCMSCs).

In this paper, a new NIR-emitting phosphor ScBO:Cr was synthesized by a high temperature solid state reaction method. Phase structure, spectroscopic properties, luminescent lifetime, quantum yield, emitter concentration influences and thermal quenching behavior of ScBO:Cr, as well as its applications for NIR pc-LEDs, were systematically investigated.

Herein, we demonstrated that single core/shell NaGdF:Yb/Er-based UCNPs (<10 nm) with a highly Yb or Nd doped shell simultaneously exhibited good upconversion luminescence (UCL), temperature sensing, and photothermal conversion properties under 980 or 808 nm excitation, respectively. The spatial separation between the emission/sensing core and the heating shell was able to tailor the competition between the light and heat generation processes, and hence higher UCL efficiency and enhanced heating capability were achieved by introducing the rational core/shell design.

Data from 23 patients with NSCLC and macroscopic residual diseasefollowing surgery (R2 resection) between March 2010 and May 2014 were retrospectively analyzed. Among these patients, 12 patients [4 with T-residual disease (incomplete resection of primary tumor but complete dissection of regional lymph node), 8 with N-residual disease (complete resection of primary tumor but incomplete resection of metastatic regional lymph node)] underwent I particle implantation during the operation, while the other 11 (4 with T-residual disease and 7 with N-residual disease) received postoperative conventional radiotherapy.

However, the application of upconversion materials is limited, due to their single and invariant emission colors.

In this work, IR-806 dye was used to increase the light absorptivity of Nd/Yb/Er tri-doped core/shell nanoparticles and then to enhance their upconversion luminescence under ∼800nm excitation. The IR-806 dye exhibited more efficient energy transfer to Nd ions than to Yb ions for subsequent upconversion emission due to the increased spectral overlap between the dye emission and Nd absorption.
