Palm Oil Methane Emissions Can Be Used as Energy Source
by dailyfusion in The Daily Fusion
An analysis published Feb. 26 in the journal Nature Climate Change (see footnote) shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the palm oil methane and using it as a renewable energy source.... Read more »

Ultrathin UV Light Absorber Developed
by dailyfusion in The Daily Fusion
Ultraviolet light (UV) has not only harmful effects on molecules and biological tissue like human skin but it also can impair the performance of organic solar cells upon long-term exposure. Researchers of Kiel University and Helmholtz-Zentrum Geesthacht have now developed a so-called plasmonic metamaterial, which is compatible with solar technology and completely absorbs UV light—despite being only 20 nanometers thin....

Influence of Temperature on Calcium Carbonate Polymorph formed from Ammonium Carbonate and Calcium Acetate
by JNSM in JScholar Publishers
This research used ammonium carbonate and calcium acetate in the preparation of various calcium carbonate polymorphs for biomimetic composite applications. Biominerals were synthesized at temperatures ranging from 25 to 80 °C to investigate the effect of synthesis temperature on the abundance of vaterite, aragonite, and calcite, delineating regions that are favorable for the formation of these different calcium carbonate polymorphs...

Evaluation of Physicochemical Characteristics of Hydrophobically Modified Glycol Chitosan Nanoparticles and their Biocompatibility in Murine Osteosarcoma and Osteoblast-like Cells
by JNSM in JScholar Publishers
Glycol chitosan, a derivative of chitosan, can be hydrophobically modified by 5ß-cholanic acid to impart amphiphilic properties that enable the self-assembly into nanoparticles in aqueous media at neutral pH. This nanoparticle system has shown initial success as a therapeutic agent in several model cell culture systems, but little is known about its stability against enzymatic degradation. The goal of this research was therefore to investigate the physicochemical properties of hydrophobica........ Read more »

Nanotechnology and Smart Materials for “More than Moore” – It’s a Small World After All!
by JNSM in JScholar Publishers
Ever since Gordon Moore fore told about the future of the integrated circuit (IC) back in 1965 [1], Moore’s law was not only an accurate forecast of the achievements that microelectronics community has made, but also was a yardstick of the appropriate level of the commercial development in microelectronics for the past five decades. Such an amazing pace of the IC technology development was possible essentially because of simple two-dimensional (2D) structure of the metal-oxide-semiconducto........ Read more »

Get the best of both worlds with Fiji’s Jython interpreter
by Juan Nunez-Iglesias in I Love Symposia!
Fiji is just ImageJ, with batteries included. It contains plugins to do virtually anything you would want to do to an image. Since my go-to programming language is Python, my favorite feature of Fiji is its language-agnostic API, which supports a plethora of languages, including Java, Javascript, Clojure, and of course Python; 7 languages in all. (Find these under Plugins/Scripting/Script Editor.) Read on to learn more about the ins and outs of using Python to drive Fiji.... Read more »

Biomass-based Nanocomposites and Mesoporous Materials
by JNSM in JScholar Publishers
The conversion of lignocellulosic biomass into fuels and chemicals has been rigorously investigated as a response to the depletion of petroleum resources, increasing demand for in oil and secure access to energy. It has been estimated that by 2030 lignocellulosic biomass could supply a substantial portion of the international chemical and transportation fuel market. Lignocellulosic biomass is usually composed of three components: 35-50 wt% cellulose, 20-40 wt% hemicellulose, and 10-25 wt% lignin........ Read more »

Nailing down the Yang-Mills problem
by Marco Frasca in The Gauge Connection
Millennium problems represent a major challenge for physicists and mathematicians. So far, the only one that has been solved was the Poincaré conjecture (now a theorem) by Grisha Perelman. For people working in strong interactions and quantum chromodynamics, the most interesting of such problems is the Yang-Mills mass gap and existence problem. The solutions of […]... Read more »

Virtual Customer Service Agents: Any Help?
by Nura Rutten in United Academics
Perhaps you are able to recall this, but there was a time that if you had a question or a complaint, you could go to a building, with a desk, and there was an actual person to talk to and get annoyed with. Nowadays, you type hours of your life away writing emails or filling in contact forms, while being on hold at the customer service for days in a row. However, not long ago, the virtual customer service agent (VCSA) appeared. ... Read more »

Slow publishing innovation
by egonw in Chem-bla-ics
Elsevier is not the only publisher with a large innovation inertia. In fact, I think many large organizations do, particularly if there are too many interdependencies, causing too long lines. Greg Laundrum made me aware that one American Chemical Society journal is now going to encourage (not require) machine readable forms of chemical structures to be included in their flagship. The reasoning by Gilson et al. is balanced. It is also 15 years too late. This question was relevant at the end of th........ Read more »
