6. New safety technology reduces transportation accidentsЧт, 01 дек[-/+]
Категория(?)  
Warehouses are home to heavy volumes of traffic. The numbers of industrial trucks (pallet trucks, forklift vehicles and the like) traversing their aisles are growing especially large—in facilities that are themselves increasing in size all the time. Under these conditions, accidents become an inevitability even if numerous safety measures are put in place.

8. Upscale hotels do not consider tourism platforms like Airbnb a threat, says studyЧт, 01 дек[-/+]
Категория(?)  
The increase in tourism and the proliferation of holiday rental platforms offering apartments, houses and rooms have completely changed the tourism landscape, particularly in large urban destinations. Taken together, these circumstances have become a major challenge for local government in cities like Barcelona. This is primarily because of the conflicts that they can create among the city's residents, and because of the issue of how the various types of tourist accommodation are regulated.

9. Using nanodiamonds to convert a greenhouse gas to an industrial raw materialЧт, 01 дек[-/+]
Категория(?)  
Rather than being released into the atmosphere and exacerbating the problem of climate change, CO2 can also be used as a raw material for substances required in industrial processes, such as formic acid or methanol. The conversion of CO2 has already been investigated in detail in laboratory studies, with nanodiamonds serving as an environmentally friendly photocatalyst. Researchers from the Fraunhofer Institute for Microengineering and Microsystems IMM are now working with partners to turn this reaction into a continuous process—bringing it much closer to real-world application.

10. Manufacturing process optimizes the production of nonwoven masksЧт, 01 дек[-/+]
Категория(?)  
Producing infection control clothing requires a lot of energy and uses lots of material resources. Fraunhofer researchers have now developed a technology which helps to save materials and energy when producing nonwovens. A digital twin controls key manufacturing process parameters on the basis of mathematical modeling.

11. Programmable home insulation that could replace air conditioning systemsЧт, 01 дек[-/+]
Категория(?)  
Energy is scarce—and like all scarce things, it comes at a price. That is why Germany needs to greatly reduce its energy consumption. There is significant potential for this in the area of heating and cooling energy which accounts for a large proportion of Germany's energy consumption. Innovative materials that can be programmed to control heat transition can be a valuable tool in this scenario. The use of materials like these could, for instance, save up to 40% of the energy used to cool single-family homes.

13. Deep-learning model extracts important data from health records to assist with personalized medicineЧт, 01 дек[-/+]
Категория(?)  
Electronic health records (EHRs) need a new public relations manager. Ten years ago, the U.S. government passed a law that required hospitals to digitize their health records with the intent of improving and streamlining care. The enormous amount of information in these now-digital records could be used to answer very specific questions beyond the scope of clinical trials: What's the right dose of this medication for patients with this height and weight? What about patients with a specific genomic profile?

14. Inexpensive airborne testbeds could study hypersonic technologiesЧт, 01 дек[-/+]
Категория(?)  
Miniature satellites known as CubeSats are taking on larger roles in space missions that might previously have been carried out by more expensive conventional spacecraft. Now, researchers at the Georgia Institute of Technology are envisioning a still larger mission for CubeSats as airborne testbeds for technologies that are being developed for future generations of hypersonic vehicles.

23. Stretchable rubber diode opens possibilities for medical, electronic devicesЧт, 01 дек[-/+]
Категория(?)  
If you are reading this article on your computer or phone, it is in part thanks to diodes. Diodes—typically rigid electrical components that easily conduct electric current in one direction—are used for a variety of critical electronic functions, from converting AC to DC and converting energy from mechanical to electrical to serving as a switch component that enables digital displays and more. Electronic devices, such as robotics or medical devices, are becoming more flexible as technology advances, so Penn State researchers have developed a fully rubbery stretchable diode that maintains performance.
