Herein the nucleation pathway of conformational polymorphs was revealed by studying the relationships and distinctions among a series of α,ω-alkanedicarboxylic acids [HOOC–(CH2)n−2–COOH, named DAn, where n = 5, 7, 9, 11, 13, 15] in the solid state and in solution. Their polymorphic outcomes, with the exception of DA5, show solvent dependence: form I with conformation I crystallizes from solvents with hydrogen-bond donating (HBD) ability, whereas form II with conformation II crystallizes preferentially from solvents with no HBD ability. In contrast, form II of DA5 does not crystallize in any of the solvents used. Quantum mechanical computation showed that there is no direct conformational link between the solvents and the resultant polymorphic outcomes. Surprisingly, solute aggregates were found in no-HBD solvents by Fourier transform infrared spectroscopy, and only monomers could be detected in HBD solvents, suggesting stronger solvation. Furthermore, it was found that all six compounds including DA5 followed the same pattern in solution. Moreover, crystal-packing efficiency calculations and stability tests stated that dimorphs of DA5 bear a greater stability difference than others. These suggest that the rearrangement from conformation II to I could not be limited by hard desolvation in HBD solvents, where form I was also obtained. In other systems, metastable II was produced in the same solvents, probably as a result of the rearrangement being limited by hard desolvation. In this work, a comparative study uncovers the proposed nucleation pathway: difficulty in desolvation has a remarkable effect on the result of rearrangement and nucleation outcome.

New research has now quantified current levels of land grabbing and demonstrated that it is accompanied by concerning levels of ‘water grabbing’ which could affect water supply in the ‘grabbed’ countries.

Climbing coconut and arecanut trees to harvest their prizes is strenuous, dangerous work, and requires a young body. But in Dakshina Kannada, India, "there is a substantial migration of well-educated youngsters to the cities for white collar jobs," K. Ganapathi Bhat told India's The News Minute. "There is a huge scarcity of employment in labour-intensive sectors like agriculture, especially those skilled in climbing trees."

"Having been born in a family with an agricultural background, it was painful to see the ripe coconut and arecanut either eaten by birds or falling across the fields," Bhat says. At 60 years of age, he's too old to climb the trees himself. But unlike most farmers, he has a Bachelors of Science in Physics, Chemistry and Maths. Thus he cobbled this together:

The bike-based contraption runs on gas, using what appears to be a chainsaw motor. After testing it out for two years on roughly 2,000 arecanut trees on his own farm, Bhat reckons the "mileage" is 90 trees per liter of gas (360 trees/gallon), and that the machine can carry an 80kg (175-pound) person to the top of a 30-meter (98-foot) tree in 30 seconds--safely. If the brakes fail, a backup brake kicks in to jam the wheels in place. As long as your tree isn't mushy and algae-covered (he tested those, too, and found the performance unsatisfactory), you're in business.

Here's more footage of the machine in action, including Bhat jumping up and down on it, to demonstrate that it safely stays in place:

Although he's been approached by several manufacturers, Bhat has turned them down, as he's not interested in profit. "I wish to partner with an organisation that would help me share the technology with the farmers to benefit them," he says. "I do not wish to seek royalties for such a venture. But I want to make sure that this product reaches as many farmers as possible, so that, in some way, it helps in the development of the overall agricultural scenario of the country."
