In nanotechnology, fungal mediated green synthesis of silver nanoparticles (AgNPs) has tremendous application in the development of antimicrobial systems but the mechanism behind the synthesis is yet to be understood. This study aims to synthesize the silver nanoparticles via a green chemistry route using mycellial aqueous extract of agriculturally beneficial fungi Trichoderma harzianum. Two diffe

A consistent framework for treating the energy dependence of fission-fragment neutron multiplicities is presented. The shape evolution of the compound nucleus towards scission is treated in the strong damping limit using the Metropolis walk method. The available excitation energy at scission is then divided statistically between the two fragments using microscopic level densities. Deformation ener

In speaking with youth leaders of the Tishreen movement from various cities across the country, what becomes obvious is that while the large lines of national renewal are agreed upon – the need for a new Iraqi identity and new basis for Iraqi nationalism, radical transformation in the practice of power – important points of fracture in their own vision as well as methods for achieving change can b

We consider depletion effects of a pear-shaped colloidal particle in a hard-sphere solvent for two different model realizations of the pear-shaped colloidal particle. The two models are the pear hard Gaussian overlap (PHGO) particles and the hard pears of revolution (HPR). The motivation for this study is to provide a microscopic understanding for the substantially different mesoscopic self-assemb

Within the context of rapid digitalisation of societies, older people increasingly require digital skills to participate civically. However, research has largely overlooked the digital dimension of older adults’ civic participation. Grounding my research in Serrat and colleagues’ (2019) later life civic participation framework, I explored digital content creation and community radio as pathways to

The World Health Organization’s age-friendly city initiative emerged as a response to the intersecting global trends of population ageing and urbanisation. However, a third global trend—digitalisation—has largely been overlooked in research and policy making relating to age-friendly cities and communities. Within the context of a general shift towards online civic participatory activities, this ar

Gaining information of species, temperature, and velocity distributions in turbulent combustion and high-speed reactive flows is challenging, particularly for conducting measurements without influencing the experimental object itself. The use of optical and spectroscopic techniques, and in particular laser-based diagnostics, has shown outstanding abilities for performing non-intrusive in situ diag

The quantizer problem is a tessellation optimization problem where point configurations are identified such that the Voronoi cells minimize the second moment of the volume distribution. While the ground state (optimal state) in 3D is almost certainly the body-centered cubic lattice, disordered and effectively hyperuniform states with energies very close to the ground state exist that result as sta

The Later Life Audio and Radio Co-operative (LLARC) is an England-widenetwork of older content creators, age-inclusive radio stations,third sector organisations, local authorities and academics workingon ageing issues. The co-operative was established in 2019 as anoutcome from a participatory action research project. Aiming topromote talk-based content created by older adults, the LLARCadvocates f

Community radio can support the process of having a voicein one’s community as a part of civic action, and promotecommunity dialogue. However, older adults are underrepresentedas producers of community radio shows in the UK,and face different challenges to their younger colleagues. Byworking within the radio production group of an existingorganisation of older adults, we identify the motivations a

The core-multishell wurtzite structure (In,Ga)As–(Ga,Al)As–(Ga,Mn)As semiconductor nanowires have been successfully grown on GaAs(111)B substrates using MBE technique. The nanowires cores were grown with gold eutectic catalyser in vapour–liquid–solid growth mode. The double shell overgrowth, on the side facets of nanowires, was performed using lower substrate temperature (about 400 ◦C, and 230 ◦C,

The Lorentz off-axis electron holography technique is applied to study the magnetic nature of Mn rich nanoprecipitates in (Mn,Ga)As system. The effectiveness of this technique is demonstrated in detection of the magnetic field even for small nanocrystals having an average size down to 20 nm.

This review covers the modern era of experimental kaonic atom studies, encompassing 20 years of activity, defined by breakthroughs in technological developments which allowed performing a series of long-awaited precision measurements. Kaonic atoms are atomic systems where an electron is replaced by a negatively charged kaon, containing the strange quark, which interacts in the lowest orbits with t

Traditional empirical formulas of Colburn heat transfer factors will lead to a design deviation for cryogenic heat exchangers. This paper employs the computational fluid dynamics (CFD) technique to numerically study the thermal performance of cryogenic compact heat exchangers (CCHEs). To obtain more precise convective heat transfer coefficients, the heat transfer performance of CCHE with serrated

Fouling on heat exchanger surfaces can weaken the heat-transfer capability, increase the energy consumption, and even cause the failure of the whole system. In coaxial heat exchangers, spirally corrugated tubes perform better than smooth ones concerning heat transfer and antifouling. In this article, a parametric study on the antifouling performance of a six-start spirally corrugated tube is carri

Owing to recent developments in CMOS technology, it is now possible to exploit tomographic microscopy at third-generation synchrotron facilities with unprecedented speeds. Despite this rapid technical progress, one crucial limitation for the investigation of realistic dynamic systems has remained: A generally short total acquisition time at high frame rates due to the limited internal memory of av

Circular business models (CBMs) promise improved resource efficiency, value creation and retention. Still, CBM operationalization among large incumbents remains slow in practice. Yet, this plays a critical role in driving industry transformations towards sustainability. Prior research outlines challenges that incumbents encounter when operationalizing CBMs - yet remains fragmented and unable to ex

Ambient air pollution is recognized as a key risk factor for cardiovascular morbidity and mortality contributing to the global disease burden. The use of renewable diesel fuels, such as hydrotreated vegetable oil (HVO), have increased in recent years and its impact on human health are not completely known. The present study investigated changes in cardiovascular tone in response to exposure to dil
