aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [ir(cod)(pme3)3]cl, (cod=1,5-cyclooctadiene), in thf to produce hydridoaminocarboxylato iridium(iii) complexes in high yields. these octahedral complexes are formed via oxidative addition reaction of the o-h bond of the carboxylic group with the central metal. the starting iridium(i) complex losses the cod molecule, the chlor...

The supply chain for metal powders used in additive manufacturing (AM) is currently experiencing exponential growth and with this growth come new powder suppliers, new powder manufacturing methods and increased competition. The high number of potential supply chain options provides AM service providers with a significant challenge when making decisions on powder procurement. This paper provides...

A set of instruments and specialized equipment is necessary to equip a laboratory to work with DNA. Reducing the barrier to entry for DNA manipulation should enable and encourage new labs to enter the field. We present three examples of open source/DIY technology with significantly reduced costs relative to commercial equipment. This includes a gel scanner, a horizontal PAGE gel mold, and a hom...

Optoelectronic devices based on graphene and other two-dimensional (2D) materials, such as transition metal dichalcogenides (TMDs), are the focus of wide research interest. They can be the key to improving bandwidths in telecommunications, capacity in data storage, and new features in consumer electronics, safety devices, and medical equipment. The characterization of these emerging atomically ...

An expected accident can happen at any time during a routine practice in the dental office due to the types of instruments used. One of the instruments used in routine dental practice is a high speed drill and a bur. If Personal Protective Equipment (PPE) is not practiced at any time in the dental office, very serious injuries could easily happen to the clinician, staff or to the patient.

On the cover: An up-to-date view of instruments in the NCNR cold neutron guide hall. DISCLAIMER Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it int...

Endoscopic surgery routinely produces video data. Automated understanding of these data has applications both online (visual servoing for telemanipulation) and offline (procedure analysis, annotation and content-based retrieval). As a step towards such applications, a method for tracking surgical instruments in endoscopic video without modifications to instruments or endoscopic equipment is des...

the prevalence of atrial fibrillation (af) is 1-2 % in the general population, and the risk of embolic stroke in af patients is 4-5 times higher than that in the general population. af-related strokes are often severe, and the rate of permanent disability is much higher among individuals who have af-related strokes than in those who have strokes unrelated to af. in patients with af, more than 9...

Over 100 syringe exchange schemes exist in the United Kingdom,' aiming at limiting the spread of HIV among drug users. The main strategy is to reduce sharing of injecting equipment by providing information about HIV and AIDS and supplying sterile equipment. If clean injecting equipment is not available the next best step is to clean used equipment properly. This approach was adopted in San Fran...
