KAUST researchers are using 3D printing with a novel calcium carbonate ink to create coral support structures that accelerate coral restoration. Their approach, named 3D CoraPrint, involves printing coral microfragments onto the structure, offering a head start for reef recovery. Two methods were developed: printing a mold for reproduction and direct printing for customization. Why it matters: This eco-friendly technique provides a potentially scalable solution to combat coral reef degradation, leveraging advanced materials and fabrication for ecological conservation in the region and beyond.
A KAUST team led by Husam Alshareef has developed a microfabricated energy storage device with high energy and power density. The device uses nickel hydroxide as an active electrode material and achieves a volumetric capacitance density of 325 F/cm3. Fabricated using chemical bath deposition at room temperature, the device can power microelectronic devices. Why it matters: This research advances energy storage technology in the region, potentially impacting the development of microelectronics and portable power solutions.
A study by MBZUAI's Preslav Nakov and Cornell co-authors examines how to develop systems that detect fake news in a landscape where text is generated by humans and machines. The research, presented at the 2024 Annual Conference of the North American Chapter of the Association for Computational Linguistics, analyzes fake news detectors' ability to identify human- and machine-written content. The study highlights biases in current detectors, which tend to classify machine-written news as fake and human-written news as true. Why it matters: Addressing these biases is crucial as machine-generated content becomes more prevalent in both real and fake news, requiring more nuanced detection methods.
Elon Musk announced that Tesla's project to build a mega AI chip fabrication facility will launch in approximately seven days. The project aims to support Tesla's AI development, particularly for autonomous driving. Tesla has been increasing its investments in AI infrastructure to train large models. Why it matters: This fab could reduce reliance on external chip suppliers and accelerate advancements in self-driving technology in the region and globally.
KAUST researchers collaborated with TSMC to review the potential of 2D materials in overcoming silicon limitations for microchips. They find that while 2D materials show promise, performance degrades when using scalable fabrication techniques like chemical vapor deposition. 2D materials have been integrated into some commercial products like sensors, but high-integration-density circuits are still a challenge. Why it matters: This research highlights the ongoing efforts and remaining hurdles in utilizing novel materials to advance semiconductor technology in line with industry roadmaps.
KAUST student Zain Ahmad won a best poster award at the 45th International Conference on Micro & Nano Engineering in Rhodes, Greece. Ahmad's poster, titled "Hydrophobic Desalination Membranes from Common Hydrophilic Materials," presented research co-authored by Ratul Das, Sankara Arunachalam, Ulrich Buttner, and Himanshu Mishra. The poster presented the first-ever membranes for water desalination using membrane distillation processes derived from water-loving materials, addressing the limitations of traditional water-repellent materials. Why it matters: This award highlights KAUST's contribution to innovative desalination technologies, crucial for water security in arid regions.
KAUST has launched vFabLab™, its first virtual lab, to provide online distance learning for semiconductor fabrication. The virtual environment trains users on end-to-end device fabrication sequences using CMOS technology. Developed by KAUST's CEMSE division, each training session includes an interactive Q&A. Why it matters: This virtual lab expands access to crucial experimental modules in semiconductor fabrication, particularly benefiting students and enthusiasts lacking access to expensive cleanroom facilities in the region.
Jhonathan Prieto Rojas completed his master's (2010) and Ph.D. (2014) in electrical engineering at KAUST under Professor Muhammad Mustafa Hussain. After six years at KAUST, he joined King Fahd University of Petroleum and Minerals (KFUPM) as an assistant professor in electrical engineering. His research at KAUST focused on micro and nanofabrication techniques, including micro-sized microbial fuel cells and flexible electronics. Why it matters: This highlights KAUST's role in developing talent and contributing to Saudi Arabia's STEM capabilities through its alumni network in other institutions.
