It is the first coal carrier to be powered by hard sail wind power propulsion technology.
The world’s first partly wind-powered bulk carrier ship sailed to the Port of Newcastle on its maiden voyage this week. The Japanese shipping company Mitsui O.S.K. Lines (MOL), which delivered the 100,422 dwt (dead-weight tonnage) bulker on October 7, 2022, sailed to Newcastle on Monday, reported Offshore Energy.

Prof. Zhang Tao’s group at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Hou Yang from Zhejiang University and Prof. Xiao Jianping from the Dalian Institute of Chemical Physics of CAS, proposed a novel two-dimensional (2D) nanoconfinement strategy to strongly enhance the oxygen evolution reaction (OER) activity of low-conductivity metal-organic frameworks (MOFs). Results were published in Nature Communications.
The development of high-efficiency electrocatalysts for the electrochemical conversion of water to generate environmentally friendly and sustainable hydrogen energy has drawn tremendous attention for decades.
Despite the crucial role the OER plays in water splitting, OER at the anode requires a relatively high thermodynamic potential to accelerate water splitting kinetics. Thanks to the large surface area, tunable porosity, diverse compositions and metal centers, MOFs have emerged as promising candidates for efficient OER electrocatalysts. However, the intrinsically poor conductivity of the most MOFs seriously impede their catalytic activity.
This harkens back to the first time he spoke about Twitter as a town square.
Elon Musk, CEO of Tesla, has now confirmed he is buying Twitter. The billionaire has tweeted a letter of sorts addressed to the advertisers who use Twitter. In the letter, Musk explains why he bought Twitter and that most of the speculation surrounding the purchase has been wrong.
Twitter is important to civilization
In the letter, which is separated into three parts, each a tweet, he starts off by saying right away that he feels Twitter is important to civilization because it provides a “town square” where a wide range of beliefs can debated in a healthy manner, without resorting to violence. This sentiment has been a staple of Musk’s feelings about the social media platform, as he has stated before in interviews.
Providing highly efficient chemical processes that are also sustainable has become a key requirement for customers of the chemicals sector. While this is easier to achieve in large-scale, continuous processes for portfolio products, reaching similar levels of sustainability in multi-stage syntheses of complex, custom-manufactured molecules remains a challenge.
One solution to this problem is hydrogenation. When operated properly and with the appropriate knowledge and expertise, this technology is able to deliver excellent yields at high selectivity, and the catalysts applied in the process can often be re-used or recycled.
Protecting People, Society & Environment — Lydie Evrard, Deputy Director General; Head, Department of Nuclear Safety & Security, International Atomic Energy Agency (IAEA)
Ms. Evrard’s department focuses on the protection of people, society and the environment from the harmful effects of ionizing radiation, whether the cause is an unsafe act or a security breach, and her team aims to provide a strong, sustainable and visible global nuclear safety and security framework. Her department was created in 1996 as a response to the Chernobyl nuclear accident.
Prior to joining the IAEA, Ms. Evrard held the role of Commissioner at the French Nuclear Safety Authority (ASN).
Ms. Evrard started her career in the field of engineering, joining the French Ministry of Energy as an engineer and she has worked extensively in the regulatory field over the last 25 years in positions including as Unit Head at the Industry, Research and the Environment Direction of France’s Ministry of the Environment (Paris Region); Deputy Head of the Paris Region Division of the Nuclear Safety Authority (ASN) and subsequently Head of the Authority’s waste, decommissioning, fuel cycle facilities, research facilities and contaminated soils remediation Department. At the ASN, Ms. Evrard handled both radiation protection and nuclear safety issues. In particular, she led, together with counterparts at the Ministry of Energy, the 2013–2015 national plan for the management of radioactive materials and waste and coordinated the stress tests performed on research and fuel cycle facilities, following the Fukushima Daiichi accident.
Mr. Musk, who runs Tesla and SpaceX, visited Twitter’s San Francisco headquarters on Wednesday and tweeted a nine-second video of himself smiling and carrying a porcelain sink into the building.
“Entering Twitter HQ — let that sink in!” he wrote.
The world’s richest man arrived at Twitter’s San Francisco offices on Wednesday ahead of a Friday deadline to complete the acquisition of the social media service.
It will also increase energy density by 30 percent.
The innovative UK start-up Ionetic, specializing in EV battery pack technology, introduced its cutting-edge EV battery pack design platform, which can shorten the time and cost of development for automakers developing new electric vehicles.
It has traditionally been expensive and time-consuming for many automobile firms to provide a high-performance and secure battery pack solution. Fully customized designs are frequently out of reach for most consumers, while current off-the-shelf battery pack solutions have low energy density and optimization. This is especially true for specialty, low-volume automakers who have particular needs.
Ultrasound sensors as small as a thumbnail can scan lithium-ion batteries to check their charge, health, and safety, a new study finds.
The findings suggest that ultrasound—that is, sound waves at frequencies higher than human hearing can detect—might one day help electric vehicles better estimate how much charge remains in their batteries. This approach might also help detect unstable batteries on the verge of disaster, quickly test battery quality during manufacturing, and identify which used batteries are healthy enough to be resold to reduce waste, says study lead author Hongbin Sun, an ultrasonic engineer at the Oak Ridge National Laboratory, in Tennessee.
Estimating how much charge is left in a commercial lithium-ion battery is currently a challenging task. For instance, electric vehicles typically experience an uncertainty of about 10 percent when estimating battery charge. This in turn reduces their driving range by about 10 percent, to ensure that they stay within their batteries’ safety margins.
