METTLER TOLEDO is pleased to announce publication of a new white paper entitled “Metal Catalyzed Transformations.” As part of METTLER TOLEDO’s Recent Advances in Organic Chemistry series, “Metal Catalyzed Transformations” covers academic examples where in situ spectroscopy supplied critical but hard-to-obtain reaction parameters in a time- and resource-saving way. The paper is available for free download at www.mt.com/webaddress?.
Authored by METTLER TOLEDO’s Adrian Burke and Dominique Hebrault, “Metal Catalyzed Transformations” reviews four recent academic examples where METTLER TOLEDO’s ReactIRTM in situ spectroscopy quickly supplied key reaction parameters—some of which had been lacking using other methodology—to researchers in highly usable graphic formats. ReactIR also allowed results collection in fewer experiments saving researchers’ time as well as materials cost.
Defining reaction start and end points—and ensuring reaction completeness—has historically presented a challenge to researchers in both academia and industry. However, IR spectroscopy, such as METTLER TOLEDO’s ReactIR, has been shown to help researchers describe mechanisms, pathways and kinetics of critical catalytic reactions. “The ability to thoroughly define these parameters is increasingly important due to the large number of complex manufacturing processes that rely on metal catalysts, which can be scarce, expensive, or both,” said Mr. Burke, head of Software and Segment Marketing for METTLER TOLEDO AutoChem. “Better process definition means more reliable reactions as well as reduced materials costs.”
The paper highlights the contexts in which ReactIR answered key reaction questions. In the first three studies, ReactIR was used to analyze reaction time-to-completion, the structure of reaction intermediaries, and reaction rate & mechanism, respectively. The fourth and final study demonstrated the power of combining structural information offered by the functional specificity of mid-IR with the kinetic information gained from in situ reaction-rate monitoring: Researchers determined that formation of an unexpected intermediary was negatively affecting racemization.
ReactIR in situ spectroscopy was shown to provide valuable information that enabled full description of the complex reactions. Results also proved complementary to other structural data such as NMR. Finally, the combination of ReactIR with METTLER TOLEDO’s iC KineticsTM software created a more robust methodology that allowed the study of reaction kinetics using fewer experiments than more traditional approaches.
“We hope this paper demonstrates how ReactIR in situ spectroscopy, when used either on its own or with other technologies, can help clarify reaction parameters in both academic and industry environments and ultimately promote more accurate, predictable and cost-effective manufacturing,” concluded Mr. Burke.

Kulula is a low-cost South-African airline that doesn’t take itself too seriously. Check out their new livery!
And have a read about their Customer Relations.WHAT A PITY KULULA DOESN’T FLY INTERNATIONALLY – WE SHOULD SUPPORT THEM IF ONLY FOR THEIR HUMOUR – SO TYPICALLY SOUTH AFRICAN.Kulula is an Airline with head office situated in Johannesburg .
Kulula airline attendants make an effort to make the in-flight “safety lecture” and announcements a bit more entertaining.
Here are some real examples that have been heard or reported:
On a Kulula flight, (there is no assigned seating, you just sit where you want) passengers were apparently having a hard time choosing, when a flight attendant announced,
“People, people we’re not picking out furniture here, find a seat and get in it!”
On another flight with a very “senior” flight attendant crew, the pilot said,
“Ladies and gentlemen, we’ve reached cruising altitude and will be turning down the cabin lights. This is for your comfort and to enhance the appearance of your flight attendants.”
On landing, the stewardess said,
“Please be sure to take all of your belongings.. If you’re going to leave anything, please make sure it’s something we’d like to have.”“There may be 50 ways to leave your lover, but there are only 4 ways out of this airplane.”
“Thank you for flying Kulula. We hope you enjoyed giving us the business as much as we enjoyed taking you for a ride.”—o0o—
As the plane landed and was coming to a stop at Durban Airport , a lone voice came over the loudspeaker:
“Whoa, big fella. WHOA!”—o0o–After a particularly rough landing during thunderstorms in the Karoo , a flight attendant on a flight announced,
“Please take care when opening the overhead compartments because, after a landing like that, sure as hell everything has shifted.”—o0o—
From a Kulula employee:
“Welcome aboard Kulula 271 to Port Elizabeth . To operate your seat belt, insert the metal tab into the buckle, and pull tight. It works just like every other seat belt; and, if you don’t know how to operate one, you probably shouldn’t be out in public unsupervised.”
“In the event of a sudden loss of cabin pressure, masks will descend from the ceiling. Stop screaming, grab the mask, and pull it over your face. If you have a small child travelling with you, secure your mask before assisting with theirs. If you are travelling with more than one small child, pick your favorite.”
—o0o—“Weather at our destination is 50 degrees with some broken clouds, but we’ll try to have them fixed before we arrive. Thank you, and remember, nobody loves you, or your money, more than Kulula Airlines.”
—-o0o—“Your seats cushions can be used for flotation; and in the event of an emergency water landing, please paddle to shore and take them with our compliments.”
—o0o—“As you exit the plane, make sure to gather all of your belongings. Anything left behind will be distributed evenly among the flight attendants. Please do not leave children or spouses..”
—o0o—And from the pilot during his welcome message:
“Kulula Airlines is pleased to announce that we have some of the best flight attendants in the industry. Unfortunately, none of them are on this flight!”
—o0o?Heard on Kulula 255 just after a very hard landing in Cape Town : The flight attendant came on the intercom and said,
“That was quite a bump and I know what y’all are thinking. I’m here to tell you it wasn’t the airline’s fault, it wasn’t the pilot’s fault, it wasn’t the flight attendant’s fault, it was the asphalt.”
—o0o?Overheard on a Kulula flight into Cape Town , on a particularly windy and bumpy day: During the final approach, the Captain really had to fight it. After an extremely hard landing, the Flight Attendant said,
“Ladies and Gentlemen, welcome to The Mother City. Please remain in your seats with your seat belts fastened while the Captain taxis what’s left of our airplane to the gate!”
—o0o?Another flight attendant’s comment on a less than perfect landing: “We ask you to please remain seated as Captain Kangaroo bounces us to the terminal.”
—o0o?An airline pilot wrote that on this particular flight he had hammered his ship into the runway really hard. The airline had a policy which required the first officer to stand at the door while the passengers exited, smile, and give them a “Thanks for flying our airline”. He said that, in light of his bad landing, he had a hard time looking the passengers in the eye, thinking that someone would have a smart comment. Finally everyone had gotten off except for a little old lady walking with a cane. She said,
“Sir, do you mind if I ask you a question?”
“Why, no Ma’am,” said the pilot. “What is it?”
The little old lady said,
“Did we land, or were we shot down?”
After a real crusher of a landing in Johannesburg , the attendant came on with,
“Ladies and Gentlemen, please remain in your seats until Captain Crash and the Crew have brought the aircraft to a screeching halt against the gate. And, once the tire smoke has cleared and the warning bells are silenced, we will open the door and you can pick your way through the wreckage to the terminal..”Part of a flight attendant’s arrival announcement:
“We’d like to thank you folks for flying with us today.. And, the next time you get the insane urge to go blasting through the skies in a pressurized metal tube, we hope you’ll think of Kulula Airways.”
—o0o—Heard on a Kulula flight:
“Ladies and gentlemen, if you wish to smoke, the smoking section on this airplane is on the wing.. If you can light ’em, you can smoke ’em.”

- You must be 18 years old or older and weigh less than 250 pounds to go skydiving. Regardless of whether or not your parents are in agreement with your skydiving, minors are not allowed to jump. If you weight too much, your parachute may not slow your descent enough and you could get seriously hurt, hence the weight limit.
- Most skydiving instructors will not let your jump alone for your first try, as you simply have not had enough experience to handle it alone. While some skydiving instructors may allow you to do so, those are few and far between. Expect to jump in tandem with an instructor the first time that you jump.
- You will need to receive training in order to be allowed up in the plane to skydive, and you should expect to spend at least a couple of hours on the ground learning about skydiving before you even think about going up into the air.
- Skydiving can be terrifying, and people with weak hearts and nearly any kind of sickness are usually not allowed to jump. You need to be in good health if you want to be allowed up on the plane for your jump.
- There are a number of risks and hazards involved in skydiving, and you should be well informed of these before you go jumping. There is always the chance that you will land wrong and injure yourself, and you need to be able to think quickly. There is usually no more than a minute between the jump and the landing, and you need to react quickly.
- Always wear the proper clothing: clothes that are not too loose but not so tight as to restrict your movement. Also, make sure that you wear running shoes or shoes that you can tie tightly. You don’t want your shoes flying off while you are in the air, and you will need shoes to absorb some of the impact of your landing.
- Remember that you will only fall for about a minute, though that could be more or less according to the height you jumped from. It feels wonderful to fall freely through the air, but you need to keep focused so you can deploy your parachute in time.
- Find a good school to learn about skydiving, as that can help you prepare for your first skydiving experience.
- Be sure that you really desire to skydive, and are not just doing it because of peer pressure or some other reason. It is a dangerous sport, and only those with the desire to do it should.
- Have fun and enjoy yourself, for that is what skydiving is all about.
