Rounded Monodisperse Fluorescent Nanodiamonds

Small, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

Small, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

The Chemical Record, EarlyView.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Synchrotron beamline setup enabling quasi‐simultaneous PXRD and XANES measurements: case study of Fischer–Tropsch catalyst reduction at 60 bar

Journal of Synchrotron Radiation, EarlyView.
This paper presents a beamline setup that allows the combination of in situ powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge structure (XANES) measurements within a single experimental cycle to investigate cobalt catalyst structures and properties under real conditions.Powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge ...

High/low temperature setups for submillimetric samples under various extreme conditions at the AILES beamline

Journal of Synchrotron Radiation, EarlyView.
Two complementary high‐ and low‐temperature experimental setups have been developed at the AILES beamline of Synchrotron SOLEIL to enable infrared and terahertz spectroscopy of submillimetric samples under extreme and well controlled pressure and temperature conditions (from 10 K to 600 K and from vacuum up to 100 GPa).

Crystalline lens dispersion

Journal of the Optical Society of America, 1981
The spectral dispersions of rabbit, rat, pigeon, and human crystalline lens material have been measured with a Pulfrich refractometer. The refractive indices all increase rapidly at the violet end of the spectrum so tat the chromatic aberrations of the eyes of these species cannot be derived adequately from Cornu's formula, as had previously been ...
