- piece of art of classical Arabic poetry إِذا المَرءُ لا يَرعاكَ إِلّا تَكَلُّفاً فَدَعهُ وَلا تُكثِر عَلَيهِ التَأَسُّفا فَفي الناسِ أَبدالٌ وَفي التَركِ راحَةٌ وَفي القَلبِ صَبرٌ لِلحَبيبِ وَلَو جَفا فَما كُلُّ مَن تَهواهُ يَهواكَ قَلبُهُ وَلا كُلُّ مَن صافَيتَهُ لَكَ قَد صَفا إِذا لَم يَكُن صَفوُ الوِدادِ طَبيعَةً فَلا خَيرَ في وِدٍّ يَجيءُ تَكَلُّفا وَلا خَيرَ في خِلٍّ يَخونُ خَليلَهُ وَيَلقاهُ مِن بَعدِ المَوَدَّةِ بِالجَفا وَيُنكِرُ عَيشاً قَد تَقادَمَ عَهدُهُ وَيُظهِرُ سِرّاً كانَ بِالأَمسِ قَد خَفا سَلامٌ عَلى الدُنيا إِذا لَم يَكُن بِها صَديقٌ صَدوقٌ صادِقُ الوَعدِ مُنصِفا26.

- We only have one month left this year. I had to do a double take when I saw my calendar. Time has flown by. At this rate, 2024 will be here before you know it. I focus on the go-green movement these days. Especially, I'm into "The Next Generation Vehicle" related article. Because I will most likely have to drive when they are put to commercial use in the future. As for Electric Vehicle(=EV), there are some different kinds of batteries. One is a "lithium ion battery" that uses "nickel", "manganese" and "cobalt"(=NMC) as a cathode material. It has high performance but is burnable and the cycle number of discharge and charge is about 700. Another is a "phosphoric acid ion battery" that uses iron based material called "phosphoric acid iron"(=LFP) as a cathode material. It is non-burnable and the cycle number is over 3000. It is also affordable. Unfortunately, it has been said that LPE has low performance compared with NMC. However, many companies have developed new technology about LPE and LPE has a competitive performance against NMC now. Therefore, LPE has recently been applied to EV in car makers such as BYD, Mercedes and Toyota. LPE still has a problem that it takes a long hours to charge car's battery. On the other hand, it is said "Solid-state battery", which has no liquid electrolyte and is entirely solid, can crack this issue. Unfortunately, it is very pricey right now, but is expected to be spreading around 2040.0 gestimmt4. Dezember 20231
