rewatching breaking bad and wow. no wonder jesse failed walter white's chemistry class. walter talks about organometallic cobalt-coordinated complexes and chirality to these public school high schoolers in what is probably their first formal introduction to chemistry. girl u gotta teach them the basics first

[teanderthalrex]

My university let me register for organometallic chem despite having no background in chemistry whatsoever.

I've decided to just see how much chem I can learn in a week and take the class anyway.

So far, I know what a mole is.

Zeise's salt, one of the earliest recorded organometallic compound

Zeise's salt is one of the earliest recorded organometallic compounds and the first discovered alkene complex. It was discovered by Professor William Christopher Zeise of the University of Copenhagen in 1827. He placed PtCl4 in boiling ethanol, evaporated the reaction solution, treated the resulting solid with potassium chloride solution, and discovered this compound, hypothesizing that it contained ethylene. The discovery of Zeise's salt sparked research in many areas of organometallic chemistry and opened up a new field of chemistry - hapticity.

Multinuclear organometallic junctions might be the key to realizing high-performance thermoelectric devices at the nanoscale, as revealed by scientists at Tokyo Tech and Korea University. The unique electronic structure of organometallic ruthenium alkynyl complexes allowed the researchers to achieve unprecedented heat-to-electricity conversion performance in molecular junctions, paving the way to molecular-scale temperature sensors and thermal energy harvesters.

The Seebeck effect is a thermoelectric phenomenon by which a voltage or current is generated when a temperature difference exists across a conductor. This effect is the basis of established and emerging thermoelectric applications alike, such as heat-to-electricity energy harvesters, sensing devices, and temperature control.

In line with the unrelenting demand for ever-smaller devices, scientists are looking for new ways to leverage the Seebeck effect at the nanoscale. One way to achieve this is by using molecular junctions, which are miniature devices consisting of two electrodes bridged by one or a few individual molecules. Depending on how sensitive these molecules are to temperature, it is possible to fine tune the thermoelectric properties of molecular junctions to match their intended application.

Thus far, most studies on molecular thermoelectrics have been limited to rather simple organic molecules. This has led to molecular junctions with a low Seebeck coefficient, which translates to poor temperature-to-voltage conversion and performance. There is therefore an ongoing challenge to design molecular junctions with better characteristics and, most importantly, a higher Seebeck coefficient.

Compounds which contain organic ligands bound to a metal ion through one or more carbon atoms are called organometallic compounds (figure 13.10).

theres a part of me that still cant accept that carbon monoxide is bad for you just because of its physical size instead of its fucked up evil and stupid valance. theres some cosmic injustice at play there that let it get away with that whole situation and let it be bad for you bc it just HAPPENS to be like the same dimensions as oxygen

I went to a seminar today!

Not the planned one on my timetable one, though. I caught a glimpse of the person I could be: confident to present in front of a crowd, engaging and answering questions... The lecturer was so cool. I learned that it is okay to not know the answer to a question; science expands, and there are unknown perspectives.

I was nervous, but I blended into a crowd. A lady adjacent to me smiled; that made me happy and feel seen. Normally, I have an aversion to being seen, yet this trivial act brought me some joy. Perhaps that is the solution: little and often.

So yeah, a less negative post today; I know that will change, though. The inevitability of sadness was why I would not allow myself to improve. Less displacement.

The Sandwich Compound, One of the "Star Molecules" of 2023 by C&EN

The Sandwich Compound🥪 features a structure resembling a sandwich: a single central metal atom sandwiched between two parallel flat aromatic organic rings. Ferrocene, the earliest and most significant sandwich compound, marks the origin of modern organometallic chemistry.

In August 2023, Professor Peter W. Roesky's research group at the Karlsruhe Institute of Technology (KIT) in Germany published groundbreaking research in Nature. They successfully sandwiched metals such as strontium (Sr), samarium (Sm), and europium (Eu) between cyclopentadienyl layers, forming an isomorphous series of circular sandwich compounds termed 'cyclocenes'.

These cyclocenes, comprising 18 repeating units, form nearly perfect closed rings in the solid state, paving the way for the development of novel functional organometallic materials (Nature 2023, DOI: 10.1038/s41586-023-06192-4). The cyclocene compounds were also recognized as one of the "star molecules" of 2023 by C&EN. #chemistry #science

Ea, Our Second Chance (15)

15. Dissection of trepangfish

(Index)

(< 14. Reproduction of Haematophyta) (> 16. Ean heraldry)

(original page)

Specimen of golden trepangfish (Dendrocephalus aureus, Wayan 27), an Actinognathan common in the oceans of Ea, as it might appear during dissection on the desk of a student of the Faculty of Marine Zoology in Leeuwenhoek, New World Academy.

The feathered ends of the oral palps sweep the seabottom, capturing micropreys and organic particles from the sediment. The mucus-covered cirri convey these particles to each mouth.

Often some palps beat the floor to raise clouds that are sifted by others. As is often the case for palps of this length, they are divided in rigid segments for reasons of mechanical efficiency.

The mouths also serve to expel waste, which mostly consists of sand and mud particles. At least one palp is always reserved to excretion when feeding. We can see a mass of feces expelled by one of the mouths. The greenish color is due to metabolic waste from blood recycling.

Each eye is protected by a calcite lens that must be shed periodically as it’s scratched by sand. The two visible eye lenses appear to be new.

As pentamerans have an open circulatory system, dissection releases a large amount of lymph. The green color is due to the organometallic copper complexes that carry oxygen around the haemocoel.

Some calcareous plates have been lifted to expose the interior organs. They are connected by thin elastic tissue that can tighten offering considerable resistance when the animal is alive, but can be easily cut after death.

The trepangfish' ring-shaped stomach, connected to all the five palps.

The digestive caeca extend deep into the haemocoel, extracting metabolic waste from it and passing back nutrients. Their walls secrete lubricating oils to protect themselves from abrasions due to sand grains.

The hydrocysts serve as distributed reservoirs of hydromuscular fluid in actinognathans, none of which appears to be more important than others, contrasting with the central role of the Vindhana organ in geopentamerans.

A water lung, extracted from its usual resting position between two caeca.

Male and female gonads appear as a nearly identical pale spongy mass. Only their extension to this level reveals that this trepangfish is a female; male gonads would cluster much closer to the genital slits for a faster maturation and release of sperm.

The hydraulic fins are mostly used to control the body’s orientation in water. They are easily lost to accidents or predation, but regenerate within days. A valve at the base stops fluid loss in this case.

The tail is mostly occupied by hydraulic muscle and gonad tissue. In this species the genital slits are completely hidden by the caudal scales.

The base of the aboral cerci carries eggs. This is not sufficient to mark the specimen as female (but see point 11), as the newly released and fertilized eggs attach to the cerci of both parents.

About half of the length of the cerci are composed by rows of fins that provide active forward propulsion to the animal. They do not move independently: the whole cercus moves as a ribbon to push water backwards. Unlike most hydraulic structures, they lose half of their size after death as fluid flows into the inner hydrocysts.

The distal part of the cerci is broad and flat, contains little fluid and remains flexible at all times. Its function is not yet fully understood.
