Nanoplaklet filmlerinde yüksek uyarım yoğunlukları altında eksitoner emisyonunun doğrusal olmayan söndürülmesini incelemektedir. Bu çalışma nanomateryal ve kuantum optik alanında önemli sonuçlar sunmaktadır.

The scalable integration of solid-state quantum emitters into photonic nanostructures remains a central challenge for quantum photonic technologies. Here, we demonstrate a robust and streamlined integration strategy that tackles the long-standing issue of deterministic fabrication on randomly positioned self-assembled quantum dots (QDs), leveraging a buried-stressor-based site-controlled InGaAs QD platform. We show that this deterministic growth approach enables precise spati

This study explores strategies to boost the productivity of solar panel operating in dusty environments by employing the Lorentz force as an active cooling mechanism. The cooling system features a trapezoidal duct equipped with fins. The duct is filled with a ferrofluid composed of water and Fe3O4 nanoparticles, and simulations were conducted for two different nanoparticle volume fractions (ϕ). The photovoltaic module is modeled as a multilayer structure, with a thermoelectri

Kral Charles, Amerika Kongresi'nde yaptığı konuşmada NATO'nun önemini vurgulayarak, Ukrayna'nın savunulması ve iklim krizine dikkat çekti. İngiltere-ABD ilişkilerinin önemine vurgu yapan konuşma, Trump'a geleneksel Avrupa ittifaklarına dönüş çağrısı olarak yorumlanmıştır.

Manganese Mercury Thiocyanate (MMTC) and Manganese Mercury Thiocyanate Di Methyl Sulfoxide (MMTD) crystals were prepared from aqueous solution using a slow evaporation process. The pure MMTC and MMTD were bombarded with electrons of 8 MeV energy in the free air environment. The samples were kept at a distance of 30 cm from the beam exit point, where an almost uniform electron beam distribution exists for an area of 8 cm x 8 cm. The dose rate was adjusted with a current of 20

Kitosan, polietilen glikol ve polipirol/karbon siyah kullanılarak yeni filmler geliştirilmiş ve bunların fiziksel özellikleri ayarlanabilir hale getirilmiştir. Bu filmler endüstriyel atıklardan boya gideriminde uygulanabilirliği test edilmiştir.

ABD'nin hava kirliliği izleme sistemi, iklim değişikliğinin neden olduğu artan orman yangınlarıyla başa çıkmakta zorlanmaktadır.

Conservation groups say work has begun in protected coastal area, while prime minister insists project will bring jobs and investment Protests in Albania over a proposed luxury resort backed by Donald Trump’s son-in-law, Jared Kushner, are set to intensify after opponents rejected an offer from the country’s prime minister “to discuss solutions”. Thousands took to the streets of Tirana for a third straight day on Wednesday, some of them brandishing inflatable flamingos in a n

The oil giant says the documents ignore the critical context of the complex operating environment at the time.

Optomechanical crystal cavities (OMCCs) display appealing features to function as on-chip photonic microwave oscillators (PMOs) when operated in the phonon lasing regime. Silicon OMCCs have so far demonstrated the best performance in terms of phase noise in a free-running configuration. Some preliminary experiments have also demonstrated that the generated microwave tone can be used for mixing wireless signals compliant with 5G standards. Still, more research is needed to ide

Effective regulation of information diffusion in complex social systems requires balancing containment and intervention cost, yet how network community structure interacts with targeted interventions remains unclear. We develop a community structure-regulation coupling framework (COSREF) that integrates community structure with process-level regulation of transmission and show how their interplay governs diffusion. Tuning two regulation parameters governing within- and cross-

Lübnan çevre bakanı, 2023-2024 yılları arasında İsrail ordusunun ülkede 'ekosite' işlediğini iddia ederek, orman alanlarının, tarım varlıklarının ve toprak kirliliğinin önemli ölçüde hasara uğradığını belirten bir rapor yayımladı.

ABD'de Mart ayında güneş ve rüzgar gibi yenilenebilir enerji kaynakları, ilk kez doğal gazdan daha fazla elektrik üretmiştir. Trump yönetiminin temiz enerjiye karşı çabalarına rağmen, yenilenebilir enerji ilerlemeyi durduramadığı görülmektedir.

Both homogeneous and inhomogeneous alloying significantly extend the spectrum of available materials and properties. In this study, (Mo,W)S2 monolayer alloys in the full composition range were grown by a modified atomic layer deposition process. The mixture of Mo and W in the crystal lattice can be controlled by the pulsed precursor schema and either a homogeneous distribution or nanostructures such as line structures and elongated islands were realized. The distribution of m

A cylindrical gate-all-around (GAA) carbon nanotube field-effect transistor (CNT FET) utilizing a semiconducting zig-zag (19,0) nanotube channel is developed for sub-10-nm technology applications. The device incorporates a conformal high-k lanthanum oxide gate dielectric forming a wrap-gate architecture, enabling strong electrostatic confinement under aggressive device scaling. To regulate carrier transport and mitigate short-channel effects, underlap engineering is systemati
