TechXtra http://www.techxtra.ac.uk/ aggregates content from a large number of different databases containing technology-related content. A search of TechXtra will search across more than 4 million records of various kinds – articles, technical reports, digital theses and dissertations, books, eprints, news items, job announcements, video, learning & teaching resources, key websites, and more – most of which relate to technology subjects. TechXtra therefore has a ‘Long Tail’, and its getting longer!
TechXtra aggregates, so that you don’t have to. From the one TechXtra search box, you can currently search 29 databases. If you need them, there are easy links to the native interfaces of these 29 databases. Hits from searches are shown by database, so you can scan their content. Sometimes this is useful, and sometimes not (we’re working on more options). If you want, you can restrict searches to a particular format (technical reports, or articles, or books, and so on), or two selected databases using the Advanced Search option.
TechXtra recently added three more databases to its cross-search:
Australian Digital Theses (ADT) (details of, and links to the full text of about 8,000 digital theses);
DiVA, technology subset (an archive containing details of doctoral and undergraduate theses and research reports from 15 of Nordic universities);
Open Video Project, a small repository of digitized video.
In the majority of cases, the full text of items found through TechXtra is freely available. This includes the 8,000 Australian theses mentioned above, nearly half a million articles in computer and information science from CiteSeer, items found via ARROW (Australian Research Repositories Online to the World), thousands of eprints from arXiv in mathematics and computer science, 300 earthquake engineering technical reports from Caltech Earthquake Engineering Research Laboratory Technical Reports, many articles from the Directory of Open Access Journals (DOAJ), theses and dissertations from NDLTD, resources from around 30 institutional open archives in the United Kingdom, learning resources from the National Engineering Education Delivery System (NEEDS), and more. We’ll shortly be adding graphics which will give a visual indication of the likelihood of being able to click-through to the full text.
Sometimes, materials found via TechXtra are not available in full text, or are only available if you, or your institution, subscribes to the service, or via pay-per-view.
In addition to the cross-search, TechXtra provides a number of other useful services, some of which have recently been expanded.Numerous new feeds have been added to the OneStep News service http://www.techxtra.ac.uk/onestepnews/ giving this wider coverage of breaking industry news. The new feeds are from: PRWeb, AZoM Materials/Engineering News, NASA Breaking News, MIT News, EETimes News, ENCMag.com News, and Automotive World News, and more.
Over 5,000 news items are currently listed.The coverage of OneStep Jobs, http://www.techxtra.ac.uk/onestepjobs/ which gives access to the very latest new job announcements has also been increased. New sources include: Total Jobs, TipTopJobs, IrishDev.com Jobs, 4ConstructionJobs.co.uk, and Eluta.
Over 7,000 new jobs are currently listed.
For those who’d like to subscribe, free, to numerous trade magazines, white papers and surveys, TechXtra has a Magazine Subscription section http://techxtra.tradepub.com/ All titles are free to professionals who qualify.Sample titles include:
Some more features will shortly be added.Here's what David Bradley, Science Writer, wrote about TechXtra:

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
