Roadmap on quantum nanotechnologies

Quantum phenomena are typically observable at length and time scales smaller than those of our everyday experience, often involving individual particles or excitations. The past few decades have seen a revolution in the ability to structure matter at the nanoscale, and experiments at the single particle level have become commonplace. This has opened wide new avenues for exploring and harnessing quantum mechanical effects in condensed matter. These quantum phenomena, in turn, have the potential to revolutionize the way we communicate, compute and probe the nanoscale world. Here, we review developments in key areas of quantum research in light of the nanotechnologies that enable them, with a view to what the future holds. Materials and devices with nanoscale features are used for quantum metrology and sensing, as building blocks for quantum computing, and as sources and detectors for quantum communication. They enable explorations of quantum behaviour and unconventional states in nano- and opto-mechanical systems, low-dimensional systems, molecular devices, nano-plasmonics, quantum electrodynamics, scanning tunnelling microscopy, and more. This rapidly expanding intersection of nanotechnology and quantum science/technology is mutually beneficial to both fields, laying claim to some of the most exciting scientific leaps of the last decade, with more on the horizon

Left behind: mereka yang ditinggalkan

Tiba-tiba saja, jutaan di seluruh dunia lenyap dalam sekejap. Kendaraan-kendaraan, yang tiba-tiba tak ada lagi yang mengemudikan, nyelonong tak terkendali. Semua orang ketakutan setengah mati ketika orang-orang yang dikasihinya lenyap di depan mata mereka. Di tengah-tengah kekacauan global, kapten pesawan Rayford Steele harus mencari keluarganya, mencari jawaban-jawaban, mencari kebenaran. Hari-hari yang paling gelap bisa saja menanti di depan, berdampak sama menghancurkannya seperti kehilangn-kehilangn yang telah terjadi selama ini. Novel ini adalah cerita tentang hari-hari terakhir di duni

The Transversal Heritage of Maastricht Stone, a Potential Global Heritage Stone Resource from Belgium and the Netherlands

Maastricht Stone is a soft and porous, pale limestone from the Krijtland, a geological region with Late Cretaceous outcrops across the border of Belgium, The Netherlands, and Germany. It has a remarkably high porosity and low strength; however, the stone is very durable in a diverse range of outdoor applications. The stone has been used since Roman times, excavated in some opencast and many underground quarries. Its main use is situated in the period between the fifteenth and first half of the twentieth century. The local community has always been strongly engaged with the production of the stone and the resulting underground landscape, which has served for secondary purposes as shelter, mushroom cultivation, and tourism. Today, the region is appreciated for this particular landscape and the recognisability of the built heritage in Maastricht Stone. The stone is a preferred substrate for scientific research in stone conservation, due to of the homogeneity of the blocks from the last remaining active quarry in combination with its specific petrophysical properties. Therefore, Maastricht Stone is proposed as a 'Global Heritage Stone Resource' to augment its visibility and understanding
