Webinar |
A webinar is a web-based seminar that combines presentation slides, audio, and video to deliver educational or technical content to a remote audience. Webinars typically include visual demonstrations, data presentations, and may feature live or recorded Q&A sessions. Participants can watch from any location with internet access. |
|
Podcast |
A podcast is a digital audio program available for streaming or download, typically released as a series of episodes. Podcasts feature conversations, interviews, or discussions on specific topics and can be listened to on-demand using computers, smartphones, or other audio devices. Unlike webinars, podcasts are audio-only and designed for portable listening. |

Carbon-free energy |
Carbon-free energy is electricity generated from sources that produce zero carbon dioxide emissions during operation. This includes nuclear power, hydroelectric, wind, solar, and geothermal energy. Unlike fossil fuels, these energy sources do not release greenhouse gases when generating electricity, making them key to reducing industrial carbon footprints. |
|
Green hydrogen |
Green hydrogen is hydrogen produced through electrolysis of water using renewable energy sources such as wind, solar, or hydroelectric power. Because the production process is powered entirely by carbon-free energy, green hydrogen generates zero carbon emissions from production through use, making it a truly clean fuel for industrial applications, transportation, and energy storage. |
|
Blue hydrogen |
Blue hydrogen is hydrogen produced from natural gas through steam methane reforming, with carbon capture and storage (CCS) technology used to trap and sequester the CO2 emissions generated during production. While not entirely carbon-free like green hydrogen, blue hydrogen significantly reduces carbon emissions compared to conventional hydrogen production and serves as a transitional technology toward a low-carbon economy. |

Cryogenic conditions |
Cryogenic conditions refer to extremely low temperature environments, typically below -150°C (-238°F). In space applications, cryogenic conditions are encountered in deep space environments, liquid fuel storage systems, and scientific instruments. These extreme temperatures pose unique challenges for materials, seals, and mechanical systems, requiring specialized components designed to maintain performance and integrity at ultra-low temperatures. |
|
Cryogenic sealing |
Cryogenic sealing involves sealing solutions designed to function reliably at extremely low temperatures where conventional materials become brittle, shrink, or lose their sealing properties. Cryogenic seals must accommodate thermal contraction, maintain flexibility at ultra-low temperatures, and prevent leakage of cryogenic fluids such as liquid hydrogen, liquid oxygen, or liquid nitrogen used in aerospace, space exploration, and industrial applications. |
