“Our materials can do much better in both sensitivity and working time than traditional materials.” “These materials could be regenerated easily under mild heating, making them candidates for air purification and environmental remediation. “A family of porous materials - like a sponge - have been developed to capture benzene vapor from polluted air and produce a clean air stream for a long working time,” explained Professor Zaworotko. Developing technologies to remove benzene from air at trace concentrations and doing it with a low energy footprint are both challenges that have not been overcome until now. Volatile organic compounds (VOCs) including benzene are a class of toxic pollutants that cause severe environmental and health issues. Professor Michael Zaworotko, Bernal Chair of Crystal Engineering and Science Foundation of Ireland Research Professor at University of Limerick’s Bernal Institute. The findings were reported in the prestigious Nature Materials journal on April 28th, 2022. Professor Michael Zaworotko, Bernal Chair of Crystal Engineering and Science Foundation of Ireland Research Professor at the University of Limerick’s Bernal Institute, and colleagues developed the new material. The researchers believe the sponge-like porous material might revolutionize the search for clean air and make a substantial contribution to the fight against climate change. The new material can capture small quantities of benzene, a harmful pollutant, from the air while using less energy than previous materialsĪ new material that can remove harmful substances from the air was created by scientists at the University of Limerick in Ireland.Īccording to the researchers, the substance uses far less energy than current materials and can capture trace levels of the harmful pollutant benzene from the air. The holes allow it to attract benzene molecules, a toxic pollutant. The actual material is full of holes and slightly resembles Swiss cheese. (Please make answers as spoiler-free as possible).Artist’s concept of the material. Sorry that I don't recall the precise names of any of them. I may have done things in an unusual order, because I don't have a light source or a double-jump, either of which would make some of these passages accessible.Ībilities I do have: wall jump, dash, super dash, as well as sharpened nail, blade whirl, vengeful soul (ranged magic attack), and downward magic strike (breaks floor). This is the most frustrating, because it seems to be crossable in theory, but it's dark and there's a crystal hunter flying around making it exceedingly difficult to get across. Only accessible with a high jump that I don't seem to have.Ī dark passage with a crystal floor. I can see the silhouette of what looks like a toll tower, but I can't interact with it. This is how I first got into the cavern, but it's now at the bottom of a long wide well with overhangs to prevent wall-jumping.Ī dark passage, blocked. You can charge a super dash on top of the adjacent platform, but the resulting way across is blocked by another wall. The first part of this long cavern is crossable with a super dash, but unfortunately the last part of the cavern has a long vertical drop following by a long width of crystal-covered floor too wide to cross with a dash. Unfortunately, all of them are inaccessible or extremely difficult. There are five things on the map which might be exits. I am playing Hollow Knight entirely blind, and I seem to have gotten myself stuck in Crystal Peak.
