Ultrasonic Additive Manufacturing (UAM) has been subject to research and investigation at Loughborough University since 2001. In recent years, three particular areas of significant focus have been: The influence of pre-process material texture on interlaminar bonding. Secure fibre positioning through laser machined channels. Freeform electrical circuitry integration. This paper details the key fin

Ultrasonic Consolidation (UC) is an additive manufacturing technology which is based on the sequential solid-state ultrasonic welding of metal foils. UC presents a rapid and adaptive alternative process, to other metal-matrix embedding technologies, for 'smart' metal composite material production. A challenge that exists however relates to optimising, for bond density and plastic flow, the interla

Ultrasonic Consolidation (UC) is a manufacturing technique based on the ultrasonic metal welding of a sequence of metal foils which are bonded to one another in a layer by layer manner. It combines the ability of additive and subtractive manufacturing techniques to create complex three-dimensional shapes. Due to moderate applied pressures and the relatively low temperatures experienced by a sample

Future 'smart' structures have the potential to revolutionize many engineering applications. One of the possible methods for creating smart structures is through the use of shape memory alloy (SMA) fibres embedded into metal matrices. Ultrasonic consolidation (UC) allows the embedding of SMAs into metal matrices while retaining the SMA's intrinsic recoverable deformation property. In this work, Ni

Yacon (Smallanthus sonchifolius Poepp. & Endl.) roots are largely grown in Andean countries and have attracted recent interest due to their antioxidant and prebiotic effects. Yacon is typically consumed as a fruit due to its sweet taste and juiciness. The macromolecular properties of an aqueous extract of yacon are investigated using asymmetric flow field-flow fractionation (AF4) coupled to UV

Periodiska systemet växer - existensen av nya supertunga grundämnen rapporteras och verifieras fortlöpande allteftersom acceleratortekniken och analysmetoderna blir alltmer kraftfulla. Vi talar om enstaka atomer av mycket kortlivade isotoper, framställda genom kärnreaktioner. Deras kemi är av naturliga skäl outforskad.Verifiering och namngivning av dessa grundämnen är en komplicerad procedur.

Myelin-sensitive quantitative (q) MRI techniques including MT (3D FLASH) and DTI (single-shot STEAM) are of growing importance to study white matter (WM) disorders in childhood. Cerebral folate transport deficiency is an inherited, treatable WM disorder with hypomyelination, developmental regression, movement disturbances, and epilepsy. One patient with this diagnosis and severe phenotype was trea

Artikeln ger en sammanfattning av IUPAC:s rekommendationer år 1994 för namnen på de nya grundämnena 101-109, de s.k. transfermierna. Rekommendationerna publiceras senare under 2014 i Pure and Applied Chemistry, Vol 66 Nr 12. Dessa rekommendationer skall under år 1995 ytterligare granskas/ratificeras av IUPACs Council, vilket slutligen kan resultera i ändringar eller omflyttningar.

The last five years of unfolding political unrest in Egypt and beyond has urged research to explore activism beyond civil society and NGO-work in the region. This has generated a turn towards social movement theory (SMT) which has revealed both the limits and possibilities of SMT when applied to different sites of the Arab world (Akder 2013, Durac 2015, Tadros 2011). While the dominant focus has b

Objective: To validate the prediction model for successful vaginal birth after cesarean delivery (VBAC) based on variables easily obtainable at the first antenatal visit, in a Spanish population. Methods: Retrospective observational study. Women with a single live fetus in cephalic presentation with one previous low-transverse CD who underwent trial of labor after cesarean delivery (TOLAC) at ≥37

Background and purpose — The annual number of total knee arthroplasties (TKAs) has increased worldwide in recent years. To make projections regarding future needs for primaries and revisions, additional knowledge is important. We analyzed and compared the incidences among 4 Nordic countries Patients and methods — Using Nordic Arthroplasty Register Association (NARA) data from 4 countries, we analy

Band gap engineering in hydrogen functionalized graphene is demonstrated by changing the symmetry of the functionalization structures. Small differences in hydrogen adsorbate binding energies on graphene on Ir(111) allow tailoring of highly periodic functionalization structures favoring one distinct region of the moiré supercell. Scanning tunneling microscopy and X-ray photoelectron spectroscopy m

Structural interactions between the endoplasmic reticular (ER) and mitochondrial membranes, in domains known as mitochondria-associated membranes (MAM), are crucial hubs for cellular signaling and cell fate. Particularly, these inter-organelle contact sites allow the transfer of calcium from the ER to mitochondria through the voltage-dependent anion channel (VDAC)/glucose-regulated protein 75 (GRP

Current paper presents the results of investigating of multifunctional Ti-Si-N coatings. Ti-Si-N coatings have been deposited using CAVD method with the aim of studying their chemical, physical, structural and mechanical properties. Coatings of Ti-Si-N were modified by high-intensity ion implantation using copper ions with dose D = 2 × 1017 ions/cm2 and energy E = 60 keV. The results demonstrated

The impedance bandwidth of a small antenna is a critical design parameter. In the present paper, we present stored energies which can be used as a tool to predict the largest possible bandwidth for antenna designs within a given region. These predictions are given in terms of the best possible Q-factor that can be attained within the region. The here presented energies are valid for structures tha

The thesis aims to compare two approaches to psychosocial rehabilitation – day centres and clubhouses – and to explore if either appears better suited to support people in mental health recovery. The recovery focus is on opportunities for engaging in meaningful daily occupations, accessibility to social interaction and factors pertaining to perceived health and well-being. The thesis consists of f
