About 70 percent of pharmaceuticals are manufactured using palladium-driven catalytic processes that are either fast or efficient - but not both. Researchers at North Carolina State University have now developed a green chemistry method that combines aspects of both processes to improve efficiency at a minimal cost of processing time.

Specifically, these palladium-driven catalytic reactions are used to connect carbons in small, organic molecules to create larger molecules for use in pharmaceuticals and other applications. Traditionally, there have been two ways to do this.

A trip to the dentist or orthodontist usually instills a sense of dread in most patients, and that's before the exam even begins. Add to that the fear of oral surgery with a painful recovery, and many people will avoid these visits at all costs. Now, one group reports a pre-clinical study in ACS Nano showing that they could potentially reduce pain and recovery time with the aid of specialized nanotechnology.

3D-printed materials commonly are soft and flexible during printing, leaving printed walls susceptible to collapse or falling over. Akke Suiker, professor in Applied Mechanics at Eindhoven University of Technology, had a Eureka moment and saw the solution to this structural problem. He developed a model with which engineers can now easily determine the dimensions and printing speeds for which printed wall structures remain stable. His formulae are so elementary that they can become commonplace in the fast growing field of 3D printing.

Engineers at Rutgers University-New Brunswick and Oregon State University are developing a new method of processing nanomaterials that could lead to faster and cheaper manufacturing of flexible thin film devices - from touch screens to window coatings, according to a new study.

Pelvic organ prolapse and stress urinary incontinence affects 50 per cent of postmenopausal women worldwide, many of whom undergo a vaginal mesh procedure
The current material used for vaginal meshing - polypropylene - has resulted in complications for thousands of women and is now banned in Australia
Sheffield scientists have developed a more suitable material, closer in characteristics to human tissue, which can be used in vaginal mesh procedures

When they turn up in family pantries or restaurant kitchens, cockroaches are commonly despised as ugly, unhealthy pests and are quickly killed. But in the name of science, Johns Hopkins researchers have put these unwanted bugs to work.

In a crowded, windowless lab, scholars and students are coaxing the insects to share some crucial locomotion tips that could help future robotic vehicles traverse treacherous terrain.

Liquid jet is utilized in various key technologies such as inkjet printing. However, most methods can eject only low viscosity liquid, which is almost the same viscosity of water. This limitation of the viscosity causes the blurring and dulling color of the ink. To solve these problems, the method of ejecting highly viscous liquid jet is required.

In a major advancement in nanomedicine, Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences, have successfully programmed nanorobots to shrink tumors by cutting off their blood supply.

Québec City, February 12, 2018--Canadians who suffer a stroke have a higher risk of dying if they are treated in a rural hospital rather than an urban one. According to a new study published in PLOS One by Université Laval researchers, the mortality rate in the months that follow a stroke is approximately 25% higher for patients treated in rural areas.

Companies like Amazon have big ideas for drones that can deliver packages right to your door. But, even putting aside the policy issues, programming drones to fly through cluttered spaces like cities is difficult. Being able to avoid obstacles while traveling at high speeds is computationally complex, especially for small drones that are limited in how much they can carry on-board for real-time processing.
