Nanophosphor integration in an optical cavity allows unprecedented control over both the chromaticity and the directionality of the emitted light, without modifying the chemical composition of the emitters or compromising their efficiency. Our approach opens a route towards the development of nanoscale photonics based solid state lighting.

Vertical Quantum Confinement in Bulk MoS.

ACS Nano

January 2025

Dto. de Física de Materiales, Universidad Complutense de Madrid, 28040 Madrid, Spain.

We experimentally observe quantum confinement states in bulk MoS by using angle-resolved photoemission spectroscopy (ARPES). The band structure at the Γ̅ point reveals quantum well states (QWSs) linked to vertical quantum confinement of the electrons, confirmed by the absence of dispersion in and a strong intensity modulation with the photon energy. Notably, the binding energy dependence of the QWSs versus does not follow the quadratic dependence of a two-dimensional electron gas.

Gout, a common chronic disease, is characterized by the formation and deposition of monosodium urate (MSU) crystal deposition in articular and nonarticular structures. Osteoarthritis (OA), the most prevalent type of arthritis, is a progressive degenerative joint disease. Previous clinical studies have reported that gout frequently affects OA joints; however, the underlying mechanism remains unidentified.

Designing a 2D van der Waals oxide with lone-pair electrons as chemical scissor.

Natl Sci Rev

January 2025

State Key Laboratory of Structural Chemistry, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Fuzhou 350002, China.

Two-dimensional (2D) van der Waals (vdW) materials are known for their intriguing physical properties, but their rational design and synthesis remain a great challenge for chemists. In this work, we successfully synthesized a new non-centrosymmetric oxide, i.e.

Parkinsons disease (PD) is considered one of the most frequent neurological diseases in the world. There is a need to study the early and efficient biomarkers of Parkinsons, such as changes in structural disorders like DNA and chromatin, especially at the subcellular level in the human brain. We used two techniques, Partial wave spectroscopy (PWS) and Inverse Participation Ratio (IPR), to detect the changes in structural disorder in the human brain tissue samples.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.
