Despite having an optimal sample for crystallization, obtaining crystals can be an arduous and unpredictable goal. The most important approaches to overcome this bottleneck were the discovery of appropriate precipitants, new methods of preparation of macromolecule samples, new methods of carrying out crystallization experiments but above all the increase of crystallization efficiency through automation.
Oral cavity carcinoma (OCC) remains an ongoing public health problem. Emerging nanotechnology provides alternative treatment approaches. This review covers the up-to-date literature in the human OCC treatment field. We explored the growing body of evidence to reveal novel and highly promising diagnostic and therapeutic applications of nanotechnology in this field. Various types of nanoparticles have been tested for applications in OCC. Imaging modalities in addition to nanocarriers are discussed.
The article provides a thorough review on advanced materials for architecture focusing on nanomaterials and on the new class of highly innovative materials, so called smart materials, illustrating their properties and their application in the building sector. The article illustrates how, thanks to the huge progress in the field of materials science, the advanced solutions available today can allow to reconcile the architectural features of the buildings with the new challenges of sustainability and energy efficiency.
Mosquitoes (Diptera: Culicidae) represent a deadly threat for millions of humans and animals worldwide. Seaweeds are an important resource for marine biotechnology and are currently investigated as sources of reducing and capping agents for the nanosynthesis of mosquitocides. Culex quinquefasciatus is a major vector of lymphatic filariasis, while chironomid midges (Diptera: Chironomidae) elicit allergic reactions. In this research, silver nanoparticles (AgNP) were biosynthesized using a cheap aqueous extract of Gracilaria edulis as reducing and stabilizing agent.
Since around 50 years ago, the academic world is developing knowledge and technology to understand and to control matter at the nanoscale in order to exploit the peculiar mechanical, electrical, optical and magnetic properties emerging when a discrete number of atoms is assembled in structures which must be described according to the weird rules of quantum mechanics.
A porous graphene based PVDF aerogel is produced through a cost-effective procedure, for possible application as sweat sensor. The aerogel samples were characterized in terms of porosity, density, morphological and electrical properties through high-resolution scanning electron microscopy (HR-SEM) and time-monitoring of the sample dc electrical resistance.
Nanotechnology has paved the way to innovative food packaging materials and analytical methods to provide the consumers with healthier food and to reduce the ecological footprint of the whole food chain. Combining antimicrobial and antifouling properties, thermal and mechanical protection, oxygen and moisture barrier, as well as to verify the actual quality of food, e.g., sensors to detect spoilage, bacterial growth, and to monitor incorrect storage conditions, or anticounterfeiting devices in food packages may extend the products shelf life and ensure higher quality of foods.
