So, this is the perfect time for me to say SPOILER ALERT, just like the Far From Home trailer starts with. I am sure many have been talking about what the trailer has to say and what it reveals. I have a few opinions on it, and we will get right into discussing them. If …

Geeklings, a very Happy New Comic Book Day to you all! How is everyone out there on this lovely Wednesday? The sun is out, the comics are fresh, and we’re here with a brand new edition of the Pull List. Seriously, what could be better? I’m not a doctor but I’m pretty sure comic books …
As a novel layered material, black phosphorus (BP) shows unexpected characteristics in many aspects including tribological application. In this work, BP was prepared through ball milling from red phosphorus (RP). The boundary lubricating properties of the BP nanosheets were investigated on a ball-on-disk tribometer as lubricating additives in polyalphaolefin oil. The micromorphologies, concentration, and composition …
In the present study, lubricating grease was developed with paraffin oil and 12-lithium hydroxy stearate metal soap as a thickening agent. MoS2 nanosheets were synthesized by hydrothermal method and functionalized with 1-octadecanethiol (i.e., MoS2-ODT). The MoS2 and MoS2-ODT nanosheets were dispersed in the grease with different concentrations to evaluate its tribological performance. Tribological results unveiled …
Nickel is element 28 in our International Year of the Periodic Table elements series. One of a select number of magnetic elements, it’s found in many of the coins of various currencies, and is also found in the heating elements in your oven and toaster. Nickel is one of those elements that you encounter a …
Dorothy Hodgkin was born on this day in 1910. She’s famed as one of only four women to have won a Nobel Prize in Chemistry, and the only British woman to have done so. This graphic takes a look at the work that earned her the prize. View more posts on chemistry history on the …
Misalignment between the shaft and the bearing of a journal bearing set may be inevitable and can negatively impact journal bearing performance metrics in many industrial applications. This work proposes a convex profile design of the journal surface to help counteract the negative effects caused by such a misalignment. A transient mass-conserving hydrodynamic Reynolds equation …
Element 27 in our International Year of the Periodic Table series is cobalt, found in pigments, jet engines, and used in the sterilisation of medical equipment. If you’re ever dabbled in painting or pottery-making, you may have come across the shade cobalt blue. It’s, as the name suggests, a blue pigment which is both used …
There are 118 elements in the periodic table – but they’re not all made in the same way. This graphic looks at some of the processes which generate elements in stars, and how the elements they can’t make are made by humans.
