Conversion.Convert Kilometers per Hour to Miles per Hour

 

26 rows · It is equal to exactly kilometers per hour. A kilometer per hour is a unit of. KPH (Kilometer per hour) = MPH (Miles per hour) Two Decimal Point Results KPH (Kilometer per hour) is equal to MPH (Miles per hour). Miles/hour to Kilometers/hour formula: [Km] = Miles x The final formula to convert MPH to KMH is: [KMH] = x = The earth is in motion. It revolves around itself and around the sun. The universe also is moving around the sun and the universe is also in orbit.

 

180 km to miles per hour.Speed, Distance & Time Calculator – calculate travel speed, distance and trip duration

10 rows · How fast is kilometers per hour in miles per hour? kilometers per hour. Example: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? First, calculate 80 * 4 = km, then convert km to miles by dividing by or by using our km to miles converter to get the answer: miles. There are many abbreviations for the unit kilometers per hour (kph, kmph, k.p.h, KMph., etc.), but “km/h” is the SI unit symbol. Mile/hour. Definition: The unit miles per hour (symbol: mph) is a measurement of speed in the imperial and United States customary systems. It expresses the number of statute miles traveled over the period of one hour.

Solar cells on nanotubes: borrowing technology from nature

While some researchers continue to improve fuel cells on methanol, Sandia National Labs, known for its careful attitude to the most affordable source of free energy – the Sun, continues to amaze the enlightened humanity with new developments. This time, the laboratory has developed a technology that allows you to convert the energy of sunlight, directing it to break the chemical bond between hydrogen and oxygen in water, converting it into hydrogen and oxygen.

The technology is based on organic nanotubes with an inorganic catalyst. By 2021, Sandia hopes to develop the first prototypes of solar panels of a new type, the input of which will be water and sunlight, and the output – hydrogen and oxygen. Since Sandia’s research is primarily aimed at finding reliable sources of alternative fuels, and, as you know, hydrogen has long been in the focus of attention of automakers. However, there are already developments aimed at using hydrogen to power portable electronic devices (for example, FEPC), so Sandia solar panels, if they are destined to be successful, will perfectly complement such developments.

Now some technical details. According to the source, Sandia organic nanotubes are based on the porphyrin protein used to transport electrons in reactions with hemoglobin, and the principle of action is similar to the mechanism of photosynthesis. In order to “assemble” a porphyrin nanotube under unnatural conditions, an aqueous solution was prepared in which porphyrin ions of opposite charge were present. Ions were created by attaching metal atoms to porphyrin molecules, which, firstly, provided a different charge required for “self-assembly”, secondly, the presence of a catalyst (platinum) was automatically ensured, and, thirdly, it made it possible to add a sufficient number of metal atoms for electronically connecting nanotubes to each other.

The source notes that other research groups have already attempted to convert sunlight into chemical energy, however, macroscopic devices have so far remained extremely ineffective. Researchers at Sandia hope that miniaturization of such devices to nanoscopic scales, “mimicking” natural photosynthetic cells, will lead to better efficiency – because everything works in nature.
