Memristors present an opportunity to make new types of computers that are different from existing von Neumann architectures, which traditional computers are based upon. In new work, researchers have demonstrated the ability to reversibly control the learning properties of memristors via optical means. They show that light can be used in a reversible manner to change the connection strength (or conductivity) of artificial memristor synapses and as well control their ability to forget i.e. we can dynamically change device to have short-term or long-term memory. The reversibility is achieved by changing the polarization of light.

Researchers have reported on improved performance of graphene-based moisture barrier layers. By combining catalytic CVD and ALD they created in scalable fashion nanolaminates of few-layer graphene and aluminium oxid. Unlike previous reports, this new approach exploits the synergy between different materials and growth techniques. These nanolaminates also are a potential material to be included in standard multi-stacked barrier layers to enhance the performance of existing ALD aluminium oxide and produce next generation moisture barriers.

Researchers demonstrate a novel assembly technique for transforming traditional state-of-the-art complementary metal oxide semiconductor (CMOS) based integrated circuits (IC) and other electronic components into LEGO-like modules by providing unique geometrical identity to each module; and assembling these 'LEGO IC' without the need for bonding or soldering but with the highest yield, accuracy and throughput required to maintain a high system performance.

Image sticking phenomena in liquid crystal (LC) devices became obvious soon after the production of the first nematic LC displays and have been a concern ever since. Now, researchers have developed a method to reduce the presence of excess ionic impurities by using a graphene electrode in the LC cell. Graphene shows high optical transmittance and high electrical conductivity, and therefore, graphene can be used as transparent electrodes.

Researchers explore cellular uptake, endocytic pathways, and intracellular dynamics of nanoparticles in HeLa cells, both in absence and presence of biomolecular corona from human plasma. They find that the biomolecular corona could act as a personalized 'endogenous trigger' affecting off-target interactions and controlling the indication for disease of clinically approved formulations. Mechanistic investigations of the biomolecular corona could contribute to a better understanding of the poor success of targeted liposomal technology.

Precise and reproducible manipulation of synthetic and biological microscale objects in complex environments is essential for many practical biochip and microfluidic applications. A new technique that offers simple, non-specific and long-lasting operation has been developed in form of an ultrasound-based method to guide microparticles in an autonomous and reproducible fashion, along with engineered topographical features - something like an automated highway system for microparticles.

Notwithstanding the progress neuroscientists have made in understanding the microscale function of single neurons and the macroscale activity of the human brain - a comprehensive understanding of the brain still remains an elusive goal. Here we review the basic concepts associated with neuroscience and the current journey of nanotechnology towards the study of neuron function by addressing various concerns on the significant role of nanomaterials in neuroscience and by describing the future applications of this emerging technology.

Currently, most graphene-based innovations are not yet at the level of large-scale commercial production. But public and private investments into graphene and its applications in products are large and whichever production methods eventually turn out to be successful, exposure to humans or the environment somewhere along the value chain or life-cycle of the material or product should be anticipated timely. A new review paper offers suggestions on how potential nanospecific safety issues can be addressed, by who and at what stage of the innovation process.
