This month, a past technology makes a comeback — plus, LED light bulbs that popped onto supermarket shelves and then disappeared look set to stage a return — Mark Nelson reports

EРЕ readers are a knowledgeable bunch, so I won’t insult your intelligence by asking if you recognise the term ‘fluidics’. However, it may be an unfamiliar term for younger readers.

Kharkiv plant VLADAR mastered the technology of production of batteries biopolyarnyh

Kharkov battery plant "VLADAR" in cooperation with the firm Atraverda (UK) has mastered the revolutionary technology of the bipolar cells, UKRINFORM reports with reference to the marketing department of the company.

The highlight of the technology is in the performance of bipolar lead-acid battery. The technology is patented by the company Atraverda (UK). Now all lead-acid batteries are a single-pole, that is made up of positive and negative plates coated with active material. This leads to more complicated geometry of the electrode arrays and the reaction uneven in the active mass of the electrodes for adjustment.

It is believed that the era of electricity began in March 1800, when the Italian physicistAlessandro Volta announced the creation of the unit, later named "voltaic pile". Volta was the first to explain the reasons for galvanic action open his compatriot physicist and anatomist Luigi Galvani, and created the first battery.
