Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance, hybrid sodium-ion battery that promises to revolutionize the energy storage industry. The battery uses sodium (Na), a chemical element that is over 1,000 times more abundant and less expensive than lithium (Li), which is the primary component in most conventional batteries.

Overcoming Sodium-Ion Battery Limitations

Sodium-ion batteries have traditionally faced challenges such as lower power output, limited storage capacity, and longer charging times compared to lithium-ion batteries. The KAIST research team, led by Professor Jeung Ku Kang of the Department of Materials Science and Engineering, addressed these limitations by integrating traditional battery anode materials with the cathodes used in supercapacitors to create a hybrid system. This innovative approach results in high storage capacity and rapid charge-discharge rates.

Optimized Design for Enhanced Performance

The team optimized the hybrid battery’s design by improving the energy storage rate of the anode materials and enhancing the relatively low capacity of supercapacitor-type cathode materials. They utilized two distinct metal-organic frameworks to synthesize the hybrid battery, creating an anode with improved kinetics and a high-capacity cathode material.

Impressive Energy and Power Densities

The fully assembled hybrid sodium-ion battery surpasses the energy density of commercial lithium-ion batteries and matches the power density of supercapacitors. With an energy density of 247 Wh/kg and a power density of 34,748 W/kg, the battery holds great potential for various industries, including electric vehicles, smart electronics, and aerospace technologies.

Publication and Impact

The findings of the research, co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, were published in the international journal Energy Storage Materials. The study, titled “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface-area O-doped cathode of 3D porous N-rich graphitic carbon frameworks for high-performance sodium-ion hybrid energy storages,” outlines the technical breakthroughs achieved and the potential applications of this new battery design.

The development of this hybrid sodium-ion battery marks a significant step toward affordable, efficient, and sustainable energy storage solutions. As the technology matures, it may play a pivotal role in the future of clean energy and advanced electronics.

Meta’s Threads social network, which recently surpassed 150 million monthly users, is aiming to further boost engagement by launching a limited-time bonus program for creators. This program is designed to incentivize creators to produce more content on the platform.

Bonus Program Details

The bonus program, which began testing in March, is currently an invite-only initiative limited to creators in the U.S. However, Meta has indicated that it may expand the program to other regions if it proves successful. Invited creators receive personalized requirements for earning bonuses, which can vary depending on the creator’s content and performance.

Requirements and Eligibility

To participate in the program, creators must have a public Threads profile and adhere to Instagram’s creator incentive terms and rules for bonuses. The program assesses the performance of Threads posts based on views and quantity. Specific guidelines determine which posts are eligible for bonuses, including:

• A minimum of 2,500 views per post
• Exclusion of posts with copyrighted material, no text, or boosted views
• Content without watermarks from other platforms such as TikTok or YouTube
• Exclusion of brand partnership posts

Monitoring Earnings and Receiving Payouts

Creators can track their earnings through the professional dashboard. To receive a bonus payout, creators may need to meet a minimum earnings threshold. If the minimum amount is not achieved, they will not receive a payout but may still be eligible for future bonus opportunities.

Impact on Creator Engagement

The bonus program may encourage creators with substantial Instagram followings to post more on Threads, potentially bringing their followers along with them. This cross-promotion is facilitated by Instagram’s integration with Threads, as suggested Threads posts appear in the app.

Artificial intelligence has taken a significant leap forward with the introduction of Memory in ChatGPT Plus. This new feature is available to all ChatGPT Plus users, with the exception of users in Korea and Europe. Memory allows ChatGPT Plus to retain key details from conversations and apply that information in future interactions, making the AI feel more like a familiar companion.

ChatGPT Plus Memory Explained

ChatGPT Plus’s Memory operates much like human memory, retaining important information from previous interactions. This can include personal details such as your age, location, or preferences. As a result, ChatGPT Plus can offer more personalized responses and shorten your conversations by incorporating the information it has remembered.

For example, if you tell ChatGPT Plus that you love houseplants, it will remember this and suggest adding more plants when you ask how to liven up your home. This memory can be managed and controlled by the user through the ChatGPT Plus settings.

How to Control ChatGPT Plus Memory

You can guide ChatGPT Plus’s Memory by sharing personal information with the AI that you want it to remember. This way, ChatGPT Plus can provide more accurate and useful responses based on your preferences and history. Memory is enabled by default, but you can turn it off if you prefer.

To manage your ChatGPT Plus memories, go to Settings/Personalization and use the toggle switch to enable or disable Memory. You can also view all stored memories and clear them as needed. When you share a detail with ChatGPT Plus, such as your love for houseplants, a notification will confirm that the Memory has been updated.

ChatGPT Plus Subscription and Temporary Chat

The ChatGPT Plus subscription, which provides access to the advanced GPT-4 model and other features like Memory, costs $20/£20 per month. OpenAI has not yet confirmed whether the Memory feature will be available to non-paying ChatGPT users.

For those who prefer not to use the Memory feature, there is a “Temporary Chat” option. This allows you to have a conversation with ChatGPT Plus without any of the details being added to its Memory. Simply select the model you want and choose “Temporary Chat” from the drop-down menu.
