Very narrow gaps make liquids crystallise partially. X-ray investigations at DESY show that in gaps just a few molecule diameters wide both, liquid and crystal properties of a material can exist at the same time. The observation of this coexistence is important for all liquids in very small cavities more
Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could prove useful to applications in optics, plasmonics, electronics and multi-stag more
Most techniques to prevent frost and ice formation on surfaces rely heavily on heating or liquid chemicals that need to be repeatedly reapplied because they easily wash away. Even advanced anti-icing materials have problems functioning under conditions of high humidity and subzero conditions, when f more
A team of mechanical engineers at the University of California San Diego has successfully used acoustic waves to move fluids through small channels at the nanoscale. The breakthrough is a first step toward the manufacturing of small, portable devices that could be used for drug discovery and mic ... more
DLS analysis is a widely applied, non-invasive method for measuring the effective size of molecules in solution. This technique yields valuable information for the characterization of molecules and particles. It facilitates formerly laborious and tim more
The analysis of oils, fat and fat contain- ing food containing food via fatty acid methyl esters (FAME) is a common task in governmental, quality control (QC) or contract research laboratories (CRO). Most often the samples are processed manually, whi more
"A little splash of liquid nitrogen hasn't hurt anybody" - this happens to be a widespread opinion in many laboratories. The real dangers connected to cryogenic gases many people had to learn firsthand, unexpected and painful. Skin irritation, cell a more
Even if you’re not a chemist, you’ll doubtless remember learning about acids back in school. They’re routinely described as strong or weak, concentrated or dilute. But what’s the difference between a strong acid and a concentrated acid? Explaining that is a little trickier than it sounds; in this gr more
Viscous liquids are a challenge in every lab that deals with them. Depending on how viscous a liquid is, pipetting is either impossible or it poses several problems that significantly reduce accuracy, precision and processing speed. In this Webinar, you learn about the basics of viscosity, how to m
Transferring liquids is part of almost every workflow in the life sciences. Some liquids like organic solvents, highly viscous or detergent-containing solutions pose special challenges to the experimenter. Pipetting them correctly requires awareness and special tools. Even everyday pipetting tasks s
Pipettes and other liquid handling instruments are widely used devices in all life sciences labs. The transfer of liquids in milliliter and microliter volumes is an essential technique in molecular and cell biology as well as biochemistry and microbiology labs in industry, academia and the healthcar
Despite improvements in our ability to manipulate ever-smaller volumes, most workflows in cell biology still use volumes of many microliters. We describe a method for creating microfluidic arrangements containing submicroliter volumes. It exploits interfacial forces dominant at the microscale to con more
The mechanical resonances of metal nanostructures are strongly affected by their environment. In this paper the way the breathing modes of single metal nanowires are damped by liquids with different viscosities was studied by ultrafast pump-probe microscopy experiments. Both nanowires supported on a more
The search for a structural origin governing the dynamical slowing down of a supercooled liquid toward glass transition is an active area of the community of amorphous materials. In the past decade, the locally preferred geometrical orderings, that is, those local polyhedral packing clusters extract more
Spain is ranked eighth, of the 10 countries surveyed in the Western European region in BMI’s BusinessEnvironment Ratings (BER) for Q111. The country has improved its position by one place and now ranksabove both Italy and Portugal. However, while Spain offers positives for investors, such as its lar more
