Luminous flux assessment of motor-vehicle light bulbs [PDF]
, 2016 Tänapäeval toimub palju liiklusõnnetusi ning üheks põhjuseks on see, et näiteks pimeda ajal ei suudeta märgata kõiki ohtusid. Tänu kehvale nähtavusele sõidetakse otsa jalakäijatele või muudele teedel asetsevatele objektidele.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.

3D Knitted Interfacial Solar Steam Generator for High‐Efficiency and Long‐Term Seawater Desalination
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The hydrophobic bottom provides buoyancy to keep the evaporator floating, and directional vertical spacer yarn supplies sufficient water. The knitted photothermal layer efficiently converts solar energy via multiple light reflections. The Marangoni effect induced by edge yarn accelerates the backflow of salt ions, preventing salt accumulation in the ...
