The automotive and aeronautic industries are looking for more lightweight materials to reduce the weight of the future cars and airplanes, and ultimately the fuel they consume and pollution they produce. Among the devices that contribute the mass of vehicles are an array of sensors. in a recent Nanotechnology article, researchers from the Institute of Microtechnologies in Bucharest, Romania, and the Academy of Sciences and Technical University in Chisinau, Republic of Moldova, report on flexible, ultra-lightweight pressure sensors based on graphene aerogel decorated by piezoelectric SnO2 or GaN nanocrystalline thin films.
Cercetătorii de la Institutul de Inginerie Electronică şi Nanotehnologii al Academiei de Ştiinţe a Moldovei, Centrul Naţional de Studiu şi Testare a Materialelor al Universităţii Tehnice a Moldovei şi Institutul de Microtehnologie din Bucureşti, sub conducerea academicianului Ion Tighineanu şi profesorului Mircea Dragoman, au elaborat senzori de presiune care cântăresc jumătate de miligram, fiind de circa 6-8 ori mai uşori decât fulgii de zăpadă.
Молдавские ученые совершили открытие в области нанотехнологий. Они разработали ультратонкие наномембраны. Рассмотреть их можно только при помощи специальных медицинских микроскопов, ведь толщина их составляет миллионную долю миллиметра. О том, где можно использовать это открытие, рассказывает корреспондент телеканала «МИР 24» Ксения Яниева.

Titanium dioxide nanotubes are widely used in devices to purify air, to make self-cleaning surfaces, in photovoltaics and sensors, and in biomedicine. Researchers in Moldova, Australia and the UK are now reporting on a new way to tailor the refractive index of these nanotubular structures using a focused laser beam. The new result could widen the potential applications for these materials even further.
In the context of the second edition of the International Conference on Nanotechnology and Biomedical Engineering in Chisinau, Acad. Ion Tighineanu, vice president of ASM, together with scientists from Germany, Sweden and Japan, participated today at broadcast "Home early" at Jurnal TV .
A Special Issue on Nanotechnologies and Nanomaterials for Electronic, Phononic and Photonic Applications of the Journal of Nanoelectronics andOptoelectronics featured prof. Ion Tiginyanu as Guest Editor in December 2012.
The Special issue presented 19 articles of researchers from Moldova, highlighting advances of the national nanotechnology and nanomaterials research.
Journal of Nanoelectronics and Optoelectronics (JNO) is an international and cross-disciplinary peer reviewed journal to consolidate emerging experimental and theoretical research activities in the areas of nanoscale electronic and optoelectronic materials and devices into a single and unique reference source. JNO aims to facilitate the dissemination of interdisciplinary research results in the inter-related and converging fields of nanoelectronics and optoelectronics.

On January 25, German Ambassador to Moldova, Matthias Meyer attended at the Technical University of Moldova the commissioning of a modern nanotechnology equipment, donated by the Alexander von Humboldt Foundation from Germany.
The event was also attended by the First vice-president of the Academy of Sciences of Moldova, acad. Ion Tighineanu and the vice-rector of the Technical University of Moldova, , assoc.prof. Dr. Valentin Amariei as well as young researchers.
During the event, the German Ambassador transmitted the donation certificate to the doctor of technical sciences Veaceslav Popa from the National Center for Materials Study and Testing. The equipment is aimed for plasma etching of passive dielectric films on a variety of devices, including sensors, detectors, transistors, etc.
