Toughening of complete solid solution cermets by graphite addition
(Elsevier, 2015)
(Ti0.95Ta0.05)(C0.5N0.5)-Co complete solid solution cermets (CSCs) were developed by a mechanochemical synthesis process and a pressureless sintering method. The effect of different percentages of graphite used as a sintering ...

Physical-mechanical behaviour and transformations at high temperature in a cement mortar with waste glass as aggregate
(Elsevier, 2020-05)
The replacement of natural aggregates with different recycled materials in mortars and concretes has fostered significant progress in the construction sector, thus reducing the need to extract virgin raw materials. The ...

On the Use of Strain Path Independent Metrics and Critical Distance Rule for Predicting Failure of AA7075-O Stretch-Bend Sheets
(MDPI, 2020-08)
The strain-based forming limit curve is the traditional tool to assess the formability of metal sheets. However, its application should be restricted to proportional loading processes under uniform strain conditions. ...

A highly sensitive microsystem based on nanomechanical biosensors for genomics applications
(Elsevier, 2006)
Microcantilever-based biosensors are a promising tool to detect biomolecular interactions in a direct way with high accuracy. We show the development of a portable biosensor microsystem able to detect nucleic acid hybridization ...

Hints on the quadrupole deformation of the (1232)
(American Physical Society, 2006-04-24)
The E2/M1 ratio (EMR) of the (1232) is extracted from the world data in pion photoproduction by means of an effective Lagrangian approach (ELA). This quantity has been derived within a crossing symmetric, gauge invariant, ...

On the assessment of the multiplicity of spaces in the acoustic environment of cathedrals: the case of the cathedral of Seville
(Elsevier, 2018-12-01)
Depending on the type of configuration to be adopted there are multiple forms of occupation of a cathedral which can significantly influence the acoustic environment. As a result, several activities with different acoustic ...

β-Hydrogen Elimination Reactions of Nickel and Palladium Methoxides Stabilised by PCP Pincer Ligands
(John Wiley & Sons, 2015)
Nickel and palladium methoxides [((iPr)PCP)M-OMe], which contain the (iPr)PCP pincer ligand, decompose upon heating to give products of different kinds. The palladium derivative cleanly gives the dimeric Pd(0) complex ...

Background Digital Calibration of Comparator Offsets in Pipeline ADCs
(Institute of Electrical and Electronics Engineers, 2015)
This brief presents a low-cost digital technique for background calibration of comparator offsets in pipeline analog-to-digital converters (ADCs). Thanks to calibration, comparator offset errors above half the stage ...

Mechanically induced self-propagating reaction of vanadium carbonitride
(Elsevier, 2015)
Vanadium carbonitrides (VCxN1−x) were prepared via mechanosynthesis from mixtures of elemental vanadium and carbon with different V/C atomic ratios under a nitrogen atmosphere using a high-energy ball mill. We obtained the ...

1.2V, 1.96mW @ 2.4GHz CMOS-90nm switched-transconductor mixer
(2010)
This paper presents the design of a fully differential double balanced switched transconductor mixer for ZigBee applications in the 2.4GHz band. It provides programmable conversion gain by using an active load stage. ...
