Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

Advanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Ultrafast Superradiant Scintillation from Isolated Weakly Confined Perovskite Nanocrystals

Advanced Materials, EarlyView.
Efficiency and scintillation velocity are critical for high‐energy and medical physics. These parameters, typically conflicting in conventional scintillators, are simultaneously optimized by exploiting the giant oscillator strength of CsPbBr3 nanocrystals, leading to radiatively accelerated (multi)excitonic emission with unity efficiency without ...

Remember the periroot sheet in orthodontic treatment of ectodermal dysplasia patients

Dental Hypotheses, 2014
Introduction: Root resorption has various etiologies. Recent studies have demonstrated a periroot sheet covering the root. The outermost layer of this sheet is the Malassez′ epithelial layer. Tooth malformations are seen in ectodermal dysplasia and it is

Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

Advanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

ASSESSMENT of bIoresorbable Screws and bone tissue in long-term period after the anterior cruciate ligament reconstruction

Клиническая практика, 2016
The use of bioresorbable materials in the anterior cruciate ligament reconstruction is a promising direction. Thus today there is no single point of view on the long-term results of using absorbable interference screws.

Bone Resorption by Osteocytes

Experimental Biology and Medicine, 1968
SummaryOsteocyte lacunae were measured in normal rats and in rats in which periosteal hypertrophy had been induced at the adductor longus-pectineus insertion. Lacunae in the cortex beneath the periosteal hypertrophy were significantly larger than lacunae in the cortex of the opposite side of the femur from the hypertrophy.
