That caffeine in your drink — is it really ‘natural?’


09 Mar 2012

That caffeine in your tea, energy drink or other beverage — is it really natural? Scientists are reporting successful use for the first time of a simpler and faster method for answering that question. Their report appears in the American Chemical Society (ACS) journal Analytical Chemistry.

Maik A. Jochmann, Ph.D., and colleagues point to the growing consumer preference for foods and beverages that contain only natural ingredients. Coffee, tea, colas, energy drinks and other caffeine-containing drinks are the most popular beverages in the world. Food regulatory agencies require that caffeine be listed on package labels, but do not require an indication of whether the caffeine is from natural or synthetic sources. The scientists set out to develop a faster, simpler method for categorizing caffeine’s origins.

Top 5 Everyday Personal Care Products You Can Make Yourself With These SIMPLE Ingredients

Lyra Nara Blog

Many people are moving over to natural, plant-based, organic personal care products and for good reason! There are many reasons to start making your own products, here are a few:

1.) It is beneficial for your health to limit the amount of exposure of toxic chemicals to the skin.

2.) It is also beneficial to the environment as less toxins will be going down the drains.

3.) You will be producing less waste from bottles and other packages.

4.) Over time, if enough people started doing this it could help put an end to animal testing.

5.) Making your own everyday personal care products can be very economical over time.

6.) It can be fun to customize and experiment with your favorite smells and oils.

7.) Making your own products can bring peace of mind as you know exactly where the ingredients are coming from and – what they are.

This Little Weed is one of the Most Useful Medicines on the Planet

New Drug Approvals


There are two major types of plantain in BC, Canada: Lance and Broadleaf. Generally, all 200-plus varieties of plantain yield the same results. It grows especially well in poor, rocky soil (such as driveways) and is often seen alongside dandelion. More often than not, you will see plantain growing in gravel pits and construction sites as nature seeks to regenerate the soil. Introduced to North America in the 1600s, it was once called “White Man’s Foot” by the Native Americans who witnessed that where the Europeans tread and disrupted the soil, plantain sprung up.

Odor Code for Food Based on a Few Volatile Substances

New Drug Approvals

thumbnail image: Follow Your Nose

The actual flavor of a food is experienced through our sense of smell rather than with our tongue. However, of the large number of volatile compounds in foods, only about 230 are involved in the scent, as reported by German scientists in the journal Angewandte Chemie. The different smells derive from characteristic combinations of three to forty of these odorants.

Highly efficient visible-light-driven photoelectro-catalytic selective aerobic oxidation of biomass alcohols to aldehydes

Highly efficient visible-light-driven photoelectro-catalytic selective aerobic oxidation of biomass alcohols to aldehydes



Green Chem., 2014, Advance Article DOI: 10.1039/C4GC00454J,!divAbstract

Paper Yajun Zhang, Guohua Zhao, Yanan Zhang, Xiaofeng Huang Highly efficient visible-light driven synergistic photoelectrocatalytic aerobic oxidation of biomass alcohols to aldehydes using Au/CeO2-TIO2 NT photocathodes under the mild conditions.

Department of Chemistry, Key Laboratory of Yangtze River Water Environment, Tongji University, Shanghai 200092, People’ s Republic of China


A green and highly efficient visible-light-driven synergistic photoelectrochemical (PEC) catalysis system was systematically demonstrated for selective oxidation of biomass alcohols to the corresponding aldehydes in an O2 atmosphere under the mild conditions by employing the Au/CeO2–TiO2 NTs as photocathodes. Results showed that the conversion of benzyl alcohols was as high as 98% and the selectivity of benzaldehyde was >99% at the bias potential of −0.8 V under the visible light irradiation for 8 h. The superior performance could be attributed to the synergistic PEC process combining both the advantages of photocatalytic and electrocatalytic activity. Furthermore, the research elucidated that the PEC activity and the conversion rate of benzyl alcohol could be effectively promoted by adjusting the potential. Interestingly, the incorporation of CeO2 nanoparticles (NPs) into the inner wall of TiO2 NTs can remarkably enhance the selectivity of the PEC oxidation reaction towards a specific direction. Additionally, the rationally designed and fabricated Au/CeO2–TiO2 NT photocathode was in favour of separating electrons and holes. A probable mechanism for the PEC selective aerobic oxidation process was proposed and discussed.

Plants recycle too

A research team from VIB and Ghent University (Belgium), and Staffan Persson from the Max Planck Institute of Molecular Plant Physiology in Potsdam (Germany) has now identified a new protein complex which is crucial for endocytosis in plants.

Cells communicate through proteins embedded in their cell membranes. These proteins have diverse functions and can be compared with antennas, switches and gates. For the well-being of the cell, it has to adjust the composition of its membrane proteins and lipids constantly. New proteins are incorporated, while old proteins get recycled or eliminated. The process by which membrane material gets internalized is called endocytosis. A research team headed by Daniël van Damme and Geert De Jaeger from VIB and Ghent University (Belgium), and Staffan Persson from the Max Planck Institute of Molecular Plant Physiology in Golm near Potsdam (Germany) has now identified a new protein complex which is crucial for endocytosis…
