Substituting nitrogen atoms for aromatic carbon atoms at specific locations within the molecular skeleton of a possible therapeutic agent can have significant effects on molecular properties critical for biological activity, such as hydrogen bonding, polarity, metabolic stability, target specificity and…
In traditional beer brewing, the progress of the fermentation process is typically checked manually, by inserting a hydrometer (beer spindle) that measures the density, from which the extract content of the wort can be derived — a procedure that not…
Achieving regulatory compliance is often viewed as overly complicated or restrictive, but a good understanding of the current regulatory landscape can help fuel business growth and efficiency When talking about modern manufacturing, few sectors experience as much regulatory scrutiny as…
In recent years, engineers at ETH Zurich have developed technology to produce liquid fuels from sunlight and air. At the heart of the production process is a solar reactor that is exposed to concentrated sunlight delivered by a parabolic mirror…
This company’s new HollowStream liquid atomizing spray nozzle (photo) provides a hollow-cone spray pattern, and features a tangential flow design. The design is vaneless, with wide-open internal features, to resist clogging while producing a uniform distribution in a ring pattern…
A new plasma-based technology is being touted as a more sustainable method for textile finishing, including water-intensive dyeing and coating processes. The Ausora process, developed by Xefco Pty. Ltd. (Eveleigh, Australia; www.xefco.com), in partnership with the Recycling and Clean Energy…
Canned motor pumps (CMPs) are designed to prevent emissions by eliminating the mechanical seal. Provided here is an overview of CMPs, along with information on common uses Emissions from process equipment not only pose safety and environmental risks, they also…
NC-520XP hearing-protection headsets (photo) are designed for use in demanding environments. They incorporate Dual Bluetooth, which enables the connection of two Bluetooth devices simultaneously (such as a smartphone or radio), enabling hands-free communication. This also allows users to listen to…
‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…
As I get older, time seems to get shorter. Although many experience this feeling, the duration of time is not changing, only our perception of it. However, in the five decades I have been involved in science, the timescale at…
