The ATP synthase of many anaerobic archaea have the unusual motor subunit c, otherwise only found in eukaryotic V1VO ATPases. The evolutionary transition from synthase to hydrolase is thought to be caused by the doubling of the rotor subunit c, followed by the loss of an ion-binding site. By purifying and reconstituting an ATP synthase with a V-type c subunit, we have unambiguously demonstrated, unexpectedly, the ability of this enzyme to synthesize ATP under physiologically relevant driving forces ranging from 90 to … Continue reading "A new site for mycobacterial ATP synthase plays a new role"
Surprising as it may sound, no one really knows what an electron is, and it is this fundamental question that has been driving much of modern physics and ultimately led to the development of quantum field theory. To answer the question "What is an electron?" This problem, you would think the first step would be to observe it. But that's easier said than done. Electrons are too small for us to see -- the smallest thing we can see is … Continue reading "What is an electron? Do you really know anything about electrons?"
Construction of the Yalong Kola photovoltaic power station, the world's largest water-light complementary power station, began Wednesday in Yajiang County, Garze Tibetan Autonomous Prefecture, Sichuan province. Kola photovoltaic power Station is the water-light complementary phase I project of Lianghekou Hydropower Station in Yalong River. The power station is located in Kola Township, Yajiang County, with an altitude of 4,000 meters to 4,600 meters. The total investment exceeds 5.3 billion yuan, the installed capacity reaches 1 million kW, the annual utilization … Continue reading "The world's largest water-light complementary power station has been built in Ganzi, Sichuan Province"
In addition to the punch material and the design of the punch itself, what are the causes of punch fracture? 1. The punch hardness is too high, the punch material is not right ---- replace the punch material, adjust the heat treatment hardness. 2. Improper material positioning, resulting in punching punch cutting side, due to uneven force breakage ---- adjust positioning or feeding device. 3.Deep Draw Stamping material does not meet the requirements, resulting in bad angle, resulting in size … Continue reading "Why is the punch of stamping die easy to break?"
The Capacitance, also known as the Capacitance, refers to the charge storage at a given potential difference. The symbol is "C". The SI unit is Farad. The commonly used capacitance units are millimetric (mF), micrometric (μF), nanometric (nF) and cuticle (pF). The specific conversion method is as follows: 1 farad (F) =1000 milieu (mF) =1000000 micromethod (μF) 1 micromethod (μF) = 1000 nano method (nF) = 1000000 skin method (pF). Capacitors are mainly used in power filtering, signal filtering, bypass, … Continue reading "Understanding capacitor elements"
A diode is a PN structure with unidirectional conductivity. P-n junction is formed on the basis of impurity of semiconductor, there is a special a qualitative physical structure, is by the p-type and n-type semiconductor through a certain method combined, formed at the interface between the two has the features of physical structure, the PN junction, it is a common physical basis of diode, triode structure, diode unidirectional conductivity is determined by it. In the PN junction two end of … Continue reading "Diodes and their Applications"
The U.S. Senate cleared a key procedural hurdle in a preliminary vote to approve the $52 billion CHIP bill, clearing the way for final passage by a vote of 64 to 34. The bill will face a final vote later this week or next week, then be sent to the House of Representatives for passage before President Joe Biden signs it into law. The bill, which includes $52 billion in subsidies and investment tax credits, aims to boost the construction … Continue reading "Us Senate votes for $52 billion CHIP Bill"
In people's eyes, chip is just a small part, and there is nothing special, but he can not be. So what exactly is a chip? Today xiaobian sorted out to share with you, let's have a look. Chips are packed with billions or even billions of transistors, mainly for processing binary digital signals. The main function of the chip is to complete the operation and processing tasks. The chip refers to the silicon chip containing integrated circuits. The chip is … Continue reading "It's a tiny chip. It's got a lot of power"
Chip is closely related to people's life and plays an important role in our life. Cars, mobile phones, electrical appliances all need chips, as long as it is related to "science and technology" products, all need to use chips, in this era of more and more developed science and technology, chips are still integrated into our life. From the essence of the chip, chip is a semiconductor and integrated circuit, with certain special functions, miniaturization of the circuit, made of … Continue reading "Why chips are everywhere in our life?"
On July 1, three days before the launch of Xiaomi's 12S series, Lei Jun, chairman and CEO of Xiaomi Group, announced a new self-developed chip on weibo: The Mi Paper G1 battery management chip. This is also the new member of thepaper.cn series chip after thepaper.cn P1 charging chip. The Paper G1 can monitor the slight changes (ISP) of internal materials of mobile phone cells caused by falls and collisions, dynamically analyze the reasonable temperature range (SOA) of batteries under … Continue reading "Another xiaomi chip"
