More Chemistry with Light! More Light in Chemistry!

by Thorsten Bach
Thumbnail image of graphical abstract

“… Why is chemistry overlooked when talking about light? Is the photon a physical particle per se? Are all important light-induced processes biological? Maybe the role of light for chemistry and the role of chemistry for light may be far less important than a few eccentric scientists would like to believe. From the perspective of a synthetically oriented photochemist, however, the facts are different …” Read more in the Editorial by Thorsten Bach.

Blue Fire Crater: Rivers of Molten Sulphur Flowing Inside an Indonesian Volcano Photographed by Reuben Wu

by Christopher Jobson

wu-3

While on a trip to visit the Ijen and Bromo Tengger Semeru volcanoes in East Java last month, Chicago-based photographer Reuben Wu captured the unusual sight of molten sulphur that flows from fumaroles at the base of the Blue Fire Crater at Ijen. The area is usually swarming with tourists, but Wu stayed after sunset until the moon rose to capture these otherworldly images.

The journey into the Ijen Caldera is not for the faint hearted. A two-hour trek up the side of the rocky volcano is followed by another 45-minute hike down to the bank of the crater. The blue fire found at the base is the result of ignited sulphuric gas that burns up to 600 degrees Celsius (1,112 degrees Fahrenheit) and can flare up to 5 meters (16 feet) into the air. It is the largest “blue flame” area on Earth.

Additional photos from Wu’s trek through Indonesia can be seen here. (via Colossal Submissions)

Palladium-Catalyzed Catellani ortho-Acylation Reaction: An Efficient and Regiospecific Synthesis of Diaryl Ketones

by Yunze Huang, Rui Zhu, Kun Zhao, Zhenhua Gu

Abstract

A palladium-catalyzed, norbornene-mediated Catellani ortho-acylation reaction was developed by the use of either acyl chlorides or acid anhydrides as acylation reagents. The addition of more than a stoichiometric amount of H2O is crucial for this transformation when acid chlorides are used, and kinetic studies indicate that the active acylation reagent is possibly an acid anhydride.

In position: A palladium-catalyzed Catellani ortho-acylation of aryl halides using either acid chlorides or acid anhydrides was developed. The reaction efficiently and regiospecifically introduces an acyl group to the position ortho to the halogen atom. Preliminary kinetic studies indicate that H2O plays an important role, and that acid anhydrides might be the active acylating reagents. TFP=tri(2-furyl)phosphine.

Six Things You Probably Didn’t Know Were Negotiable

by Kristin Wong on Two Cents, shared by Andy Orin to Lifehacker

If you’ve ever bought a car, you probably did a little haggling. We’re used to flexing our negotiation muscles for things like vehicles and salaries, but there are a number of other expenses that are perfectly negotiable, if you’d only try. Here are six of those costs, and how you can negotiate them.

Gaming Computers Offer Huge, Untapped Energy Savings Potential

by timothy
Required Snark writes: According to Phys.org, a study by Evan Mills at Berkeley Lab shows that "gamers can achieve energy savings of more than 75 percent by changing some settings and swapping out some components, while also improving reliability and performance" because "your average gaming computer is like three refrigerators." Gaming computers represent only 2.5 percent of the global installed personal computer (PC) base but account for 20 percent of the energy use. Mills estimated that gaming computers consumed 75 TWh of electricity globally in 2012, or $10 billion, and projects that will double by 2020 given current sales rates and without efficiency improvements. Potential estimated savings of $18 billion per year globally by 2020, or 120 terawatt hours (TWh) are possible. Mills started the site GreeningtheBeast.org. You can read the full paper as a PDF.

“Being Poor,” Ten Years On

by John Scalzi

Ten years ago today, I put the essay “Being Poor” on Whatever. I wrote the piece, as I explained later, in a rage at the after-events of Hurricane Katrina, when so many people asked, some genuinely and some less so, why many of the poor people didn’t “just leave” when the hurricane smashed into the Gulf Coast and New Orleans flooded. I wrote it not to offer a direct explanation but to make people understand what it was like to be poor, as I had been at various times in my life, and could therefore speak on with some knowledge. The piece wasn’t about how people became poor, or why there were poor — simply what it was like to be poor, and to then try to get through one’s life on a day-to-day basis.

I posted it because I had to. I was in a rage at what was happening in New Orleans in 2005, but I was also sick, literally physically sick about it, and for days I couldn’t understand why. I had no direct connection to New Orleans and there was no one there I considered a friend, and other, equally terrible disasters had hit the US before and had nowhere near the same effect on me. Ultimately I began to realize the difference this time was that I was aware how differently the disaster affected people along economic lines, and how the lack of useful planning and response to the disaster essentially punished New Orleans’ poor.

I was not of New Orleans and I was not of New Orleans’ poor. But having been poor in my life, I remembered the difficulties being poor imposes, the lack of options it offers, and circumstances it presents, when no way through is a good one. I had been there in my life, and the lack of understanding I saw radiating out from people about the situation made me sick almost to the point of vomiting. I had to do something or I felt like I would explode.

We had donated money, of course. But it wasn’t enough. So I sat down to write something, anything. What I came up with was a list of things from my personal experience and from the experience of people I knew in my life about poverty and what it was like to be in it. Later some people said the piece was a poem, and I can see that, and they might be right. At the time that wasn’t part of my thinking. I just wanted to get what was in my brain out into the world. I cried as I wrote it, putting the rage and sickness I felt into words. Then I posted it up on Whatever.

And it ended up going everywhere.

It was reprinted in the Chicago Tribune and the Dayton Daily News and dozens of other newspapers. It was linked to and pasted onto hundreds of Web sites. It was read out loud on the radio. It was shared in emails and mailing lists. Eventually it made its way into textbooks and other teaching materials. Churches and religious groups by the score asked permission to use it. In an age before Facebook and Twitter (and even MySpace, really), the piece went massively viral. I encouraged this, of course. As famously “pay me” as I am, “Being Poor” is one piece I have never taken money for. I allow it to be freely distributed and when people ask about payment, I tell them to donate to a local hunger or poverty charity. It’s meant to be shared and read, and read as widely as possible.

It continues to be read, a decade on. There hasn’t been a year since it was posted that it hasn’t been one of the most visited entries on Whatever; this year, it’s currently the third most-read piece on the whole site. Year in and year out, people find it, or come back to it. This makes me very happy.

Which is not to say that people didn’t find ways to try to pick it apart. When the piece came out, I didn’t go out of my way to note that the piece was based on my own experience, so a number of people questioned the veracity of the piece, and my right to write it. When I did make it clear that the piece was largely based on my own experience, some folks then wanted to maintain that I hadn’t really been poor, or that “American” poor is not really poor compared to the poverty elsewhere in the world, or they would focus on one particular bit in the piece and declaim how it was in some way inauthentic, therefore throwing out the whole piece. Others simply wanted to blame the poor for being poor in the first place.

There is of course not much to be done in those cases. I lived my poverty; I don’t need other people to decide whether I was poor enough for them. The American version of poverty may be “better” than poverty elsewhere, but it’s bad enough, both objectively and in context. And while I understand some people prefer to believe poor people deserve the poverty they’re in, I know it’s not true, or at the very least, is such a small part of why people are poor. I didn’t deserve to be poor when I was a child; I just was. The people I know now in poverty aren’t there because it’s some sort of cosmic or karmic justice; they work hard and try to better their lives. But the fact of poverty is: It’s a rough climb out, and a steep fall back, and it’s not as if everyone starts out in the same place.

That said, I admit to being an imperfect vessel to speak to poverty in America. I have been poor in my life. I am not now, nor have I been anything close to poor for my entire adult life. In fact I am on the opposite end of the spectrum. You can even say that in many ways my life encapsulates the Horatio Alger “rags to riches” American Dream narrative that we have embedded into our national DNA: Scrappy ambitious kid takes his chances and makes a few breaks for himself and comes out on top. It can happen to you too!

Except the thing I know that gets elided here is that I’m one of the very few “rags to riches” tales I know of. Anecdote is not data, and the data says that it’s tougher to move up the socio-economic ladder here in the US than it is in most other industrialized nations. Not impossible, and I am here to speak to that. But tougher. And I am here to speak to that too — because I know the breaks that I caught, including the fact that I got a scholarship to attend one of the best college preparatory high schools in the country, which I attended while simultaneously living in a trailer park. I was launched into the ranks of the socio-economic elite and I haven’t come back down. But I also know that not every kid in a trailer park gets the break I did, a break contingent on one school deciding to let me in, not a state or national will to make things better for poor children in general.

I have been poor, and am not. That makes me not the best spokesman for poverty. But I continue to see poverty, where I live and in the lives of people I know, and I am in a position where when I talk, people often listen. So this is a thing I will continue to speak on.

And it is a reason why I’m glad “Being Poor” continues to be part of the conversation on poverty. For what it’s done and what it continues to do, I’m proud to have written it. It’s one of the best things I’ve ever written.
