Currently working as a process engineer in O&G for an engineering firm. If I make a switch, which industry should I transition to? Renewable energy, mining & metals or chemical and manufacturing.

As the title says, I currently work in O&G and love it. I really enjoy the team i work with and the refinery is a very cool environment to work in. But i do fear about job security due to the market transitioning to renewables. My firm works in other industries and was wondering if i were to make a switch, which one would be more beneficial to be in?

How to find the Lewis dot diagrams for transition metals?

Hello! Can someone please explain to me how to draw the Lewis diagrams for transition metals? I understand how to find the valence electrons based on the electron configuration. For elements 27+, they begin having more than 8 valence? Please help I am confused!

Thought experiment: Could hydronium (H3O+) act as a ligand to a transition metal?

I was thinking about stuff related to my research and was considering the series M–[CH3]^– , M–NH3, M–[OH3]^+ . There are surely tens of thousands of metal methyl and metal ammine complexes, but what about metal hydronium complexes? After all, [CH3]^– , NH3 and [OH3]^+ are all isoelectronic, and [OH3]+ has a lone pair of electrons that can participate in a Lewis acid-base interaction with a metal, so why not? A quick Google search yielded nothing obvious, however. Has anyone ever heard of this before or know an example of a metal hydronium complex?

Transition Metal Complexes as Catalysts for the Electroconversion of CO2: An Organometallic Perspective

This review article illustrates and categorizes the currently favored molecular mechanisms for the electrochemically induced transformation of CO2 promoted by homogeneous transition metal complexes. The resulting insights are corroborated by the concepts and elementary steps of organometallic catalysis to derive strategies to broaden the molecular diversity of products.

Abstract

The electrocatalytic transformation of carbon dioxide has been a topic of interest in the field of CO2 utilization for a long time. Recently, the area has seen increasing dynamics as an alternative strategy to catalytic hydrogenation for CO2 reduction. While many studies focus on the direct electron transfer to the CO2 molecule at the electrode material, molecular transition metal complexes in solution offer the possibility to act as catalysts for the electron transfer. C1 compounds such as carbon monoxide, formate, and methanol are often targeted as the main products, but more elaborate transformations are also possible within the coordination sphere of the metal center. This perspective article will cover selected examples to illustrate and categorize the currently favored mechanisms for the electrochemically induced transformation of CO2 promoted by homogeneous transition metal complexes. The insights will be corroborated with the concepts and elementary steps of organometallic catalysis to derive potential strategies to broaden the molecular diversity of possible products.

Why do some substances (like metals) have "smooth" phase transitions from solid to liquid (where they go from hard, to malleable, to soft, to liquid), but others (like water) are binary hard/ soft?

Also, is it possible to have such a "smooth" transition between gas and liquid?

[High School: Stoichiometry] Valence of Transition Metals

On my Chemistry tests, there are a bunch of questions that I have no idea how to answer. I think they’re about valence of transition metals. for example:

What is the valence of a phosphorus atom?

What is the valence of each chromium atom in the compound Cr(PO4)2?

What is the valence of each gold atom in the compound Au(CN)3?

My teacher is not very good, he just goes on tangents about unrelated subjects. I tried to Google but I swear nothing comes up.

Looking for cool transitions in Prog Metal

First off, there is probably a term for what I'm about to describe, so feel free to fill me in. I'm looking for parts in songs where the instruments stop for a short while and vocals preferably screams take over for a couple of seconds. I'll provide some examples from the top of my head.

Edge of Sanity - Crimson 1 (2:40)

Leprous - Contaminate Me (1:25) (Ihsahn's scream in the live version at Rockefeller music Hall is absolutely diabolical)

So basically I'm looking for these kinds of little parts in songs. I'd appreciate any other transitions you could recommend that gives you goosebumps and hypes you up or has any other effect on you.

1D Coordination π–d Conjugated Polymers with Distinct Structures Defined by the Choice of the Transition Metal: Towards a New Class of Antiaromatic Macrocycles

The on‐surface synthesis approach under UHV conditions has led us to the formation of 1D coordination π–d conjugated polymers on metal surfaces. The reaction of quinoidal ligand with different transition metals results in two distinct coordination motifs: four‐fold (Cr, Fe, Co, Ni) and two‐fold (Cu). The backbone of the Cu‐coordinated 1D chain is formed by antiaromatic 12‐membered macrocycles.

Abstract

Recently π–d conjugated coordination polymers have received a lot of attention owing to their unique material properties, although synthesis of long and defect‐free polymers remains challenging. Herein we introduce a novel on‐surface synthesis of coordination polymers with quinoidal ligands under ultra‐high vacuum conditions, which enables formation of flexible coordination polymers with lengths up to hundreds of nanometers. Moreover, this procedure allows the incorporation of different transition‐metal atoms with four‐ or two‐fold coordination. Remarkably, the two‐fold coordination mode revealed the formation of wires constituted by (electronically) independent 12‐membered antiaromatic macrocycles linked together through two C−C single bonds.

A Simple Homoleptic Gallium(I) Olefin Complex: Mimicking Transition‐Metal Chemistry at a Main‐Group Metal?

The yet underdeveloped coordination chemistry of GaI species won a new addition to their family. With an unprecedented bonding situation in main‐group chemistry, the complex salt Ga(COD)2+[Al(ORF)4]− (COD=1,5‐cyclooctadiene; RF=C(CF3)3) offers novel options. Its properties are compared with respect to those of related transition‐metal species.

Abstract

The earth‐metal olefin complex [Ga I (COD)2]+[Al(ORF)4]− (COD=1,5‐cyclooctadiene; RF=C(CF3)3) constitutes the first homoleptic olefin complex of any main‐group metal accessible as a bulk compound. It is straight forward to prepare in good yield and constitutes an olefin complex of a main‐group metal that—similar to many transition‐metals—may adopt the +1 and +3 oxidation states opening potential applications. Crystallographic‐, vibrational‐ and computational investigations give an insight to the atypical bonding between an olefin and a main‐group metal. They are compared to classical transition‐metal relatives.

Insight into the Transition‐Metal Hydroxide Cover Layer for Enhancing Photoelectrochemical Water Oxidation

By taking BVO/F x N4−x ‐H as a model, we directly track the behavior of hole transfer. Through a system dynamics analysis of the key charge transfer and surface catalytic reaction at the different interfaces, we clarify that F x N4−x ‐H here acts as an interfacial charge transporter. PEC performance is mainly enhanced by efficiently suppressing BVO/F x N4−x ‐H interface charge recombination.

Abstract

Depositing a transition‐metal hydroxide (TMH) layer on a photoanode has been demonstrated to enhance photoelectrochemical (PEC) water oxidation. However, the controversial understanding for the improvement origin remains a key challenge to unlock the PEC performance. Herein, by taking BiVO4/iron‐nickel hydroxide (BVO/F x N4−x ‐H) as a prototype, we decoupled the PEC process into two processes including charge transfer and surface catalytic reaction. The kinetic information at the BVO/F x N4−x ‐H and F x N4−x ‐H/electrolyte interfaces was systematically evaluated by employing scanning photoelectrochemical microscopy (SPECM), intensity modulated photocurrent spectroscopy (IMPS) and oxygen evolution reaction (OER) model. It was found that F x N4−x ‐H acts as a charge transporter rather than a sole electrocatalyst. PEC performance improvement is mainly ascribed to the efficient suppression of charge recombination by fast hole transfer kinetics at BVO/F x N4−x ‐H interface.

Insulating metal door transition

Looking for some advice on how to keep the cold out of my bedroom. My room has a door/window to get onto the deck, and the transition(?) is metal. It seems to be transferring the cold air from outside into the room which is causing condensation. Is there anything I can do to stop the heat transfer without replacing the transition with something more insulating? Here’s a picture, thanks. https://imgur.com/a/ypQG7Ng

Any good segue bands to transition from Prog rock to prog metal?

I’ve listened to prog rock for a while now, and want to start appreciating prog metal as well, but I find the sound a bit grating still and want to find some bands that toe the line between the two genres as a way of easing myself in. Are there any good recommendations? I can currently listen to a band like Rush pretty comfortably but find something like TOOL a bit grating still, but I am getting used to it.
