Nice paper on Majorana fermions for information units in QC.

Majorana bound states in one-dimensional nanowires have attracted wide attention in recent years due to their potential use as qubits for topological quantum computation based on braiding.

It’s a super capacitor made with nano-materials, but all you need to know is—if it’s commercialized—your days of worrying about your battery might be over.

MNA– Head of Iran Nanotechnology Initiative Council and Iran’s envoy to Armenia met with Armenian Minister of Transport, Communication and IT in Yerevan.

Seyed Kazem Sadjadi, the Ambassador of the Islamic Republic of Iran to Yerevan and Professor Saeed Sarkar, Secretary-General of the Iran Nanotechnology Initiative Council (INIC) met with Vahan Martirosyan, the Minister of Transport, Communication and Information Technology of the Republic of Armenia on Wednesday in Yerevan.

The Armenian minister in the meeting welcomed the Iranian delegation for initiating cooperation and underlined that cooperation with Iran in areas of transportation and communication was of prime importance to Armenia. He voiced hope for expansion of bilateral cooperation in information technology.

Ora, a Montreal-based tech start-up, has announced that it has developed the first consumer-ready graphene loudspeaker.

The company believes that graphene holds the ideal properties sought after in loudspeaker diaphragms: stiffness (graphene is stronger than diamond) and lightness (graphene is the thinnest known material, one atom thick).

University of Central Florida researchers have developed a radical new supercapacitor design that could one day replace lithium-ion batteries, allowing users to charge a mobile phone in a few seconds and with a charge that lasts a week, according to the researchers. The new battery would be flexible and a fraction of the size of a lithium-ion battery.

The proof-of-concept design is based on a hybrid supercapacitor composed of a core with millions of highly conductive nanowires coated with shells of two-dimensional materials. It combines fast charging and discharging (high power density) and high storage capacity (high energy density).

Machines lace almost all social, political cultural and economic issues currently being discussed. Why, you ask? Clearly, because we live in a world that has all its modern economies and demographic trends pivoting around machines and factories at all scales.

We have reached the stage in the evolution of our civilization where we cannot fathom a day without the presence of machines or automated processes. Machines are not only used in sectors of manufacturing or agriculture but also in basic applications like healthcare, electronics and other areas of research. Although, machines of varying types had entered the industrial landscape long ago, technologies like nanotechnology, the Internet of Things, Big Data have altered the scenario in an unprecedented manner.

The fusion of nanotechnology with conventional mechanical concepts gives rise to the perception of ‘molecular machines’. Foreseen to be a stepping stone into nano-sized industrial revolution, these microscopic machines are molecules designed with movable parts that behave in a way that our regular machines operate in. A nano-scale motor that spins in a given direction in presence of directed heat and light would be an example of a molecular machine.

Terahertz (THz) radiation is used today most prominently for security screening at the airport. It’s the machine you stand in with your hands up as it swings its scanning arms in front and behind you. In medicine, terahertz imaging has the potential to help diagnoze certain types of cancer and to monitor a variety of health parameters to aid in assessment of overall health. Because of the extremely short length of terahertz waves, this imaging modality has a lot of limitations, including shallow penetration into tissues, and that prevents it from being used more widely. Yet, since it’s non-ionising, it’s probably safe and may even replace dangerous X-rays for some applications.

Currently, terahertz imaging is very poor at scanning curved surfaces even though it can peer a few millimeters deep into some tissues. To overcome this, researchers at Tokyo Institute of Technology have developed a flexible and even wearable terahertz scanner that can image curved 3D surfaces such as our skin.

Lenses with a surface accuracy in the nanometer range are behind ever more accurate laser and optical systems. Manufacturers depend on ultra-precise optical and mechanical ablation processes, innovative coating processes and extremely accurate measuring technology to venture into these nano-worlds. The latest trends in optical manufacturing will be showcased by the world’s leading trade fair LASER World of PHOTONICS, from June 26–29, 2017 in Munich.

The diversity of lenses, their shapes, sizes and materials is growing all the time. Applications in non-visible wavelengths from x-rays and ultraviolet to the far infrared also require special optics, such as material processing using short pulse and ultrashort pulse lasers or imaging techniques in the medical and research fields and industrial quality control.

Immensely concentrated sunlight provides a novel method for the synthesis of many nanomaterials that possess remarkable photonic, tribological, electronic, and catalytic properties.

The solar paradigm of creating singular nanomaterials that possess unprecedented photonic, tribological, electronic, and catalytic properties is arguably far less familiar than the energy-saving paradigms of solar photovoltaics and solar thermal systems. Much of the research in this field has evolved over the past decade from our collaborations (i.e., between researchers at Ben-Gurion University of the Negev and the Weizmann Institute of Science, Israel).
