Due to surface effects and quantum size effects, nanomaterials have properties that are vastly different from those of bulk materials due effects. The particle distribution plays an important role in chemical physical properties. measurement control this parameter crucial for nanomaterial synthesis. Dynamic light scattering (DLS) is a fast non-invasive tool used measure size, stability solution...

Abstract Power-to-methane technology is a promising solution to facilitate the use of excess variable renewable energy for biomethane production. In this approach, hydrogen produced via electrolysis used upgrade raw biogas, which can be subsequently as fuel or stored in gas grid. Ex-situ biomethanation an emerging that could potentially replace conventional energy-intensive biogas upgrading met...

Donor organ shortage continues to limit the availability of liver transplantation, a successful and established therapy of end-stage liver diseases. Strategies to mitigate graft shortage include the utilization of marginal livers and recently ex-situ normothermic machine perfusion devices. A 59-year-old woman with cirrhosis due to primary sclerosing cholangitis was offered an ex-situ machine pe...

Introduction Continuous efforts are invested in developing improved NMR techniques to characterize metabolism. Particularly pressing is the need to enhance NMR’s sensitivity. The last years have witnessed what promises to become a major development in this area, with the advent of ex situ dynamic nuclear polarization (DNP). The long transfer times needed by this ex situ approach imply that only...

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sit...

This study aimed to establish a cryopreservation protocol for embryogenic cultures of A. angustifolia, enabling the ex situ conservation of the species. Embryogenic cultures were established from immature seeds and treated with variations of the cryoprotectant solutions SuDG, SoD and PVS2 prior to immersion in liquid nitrogen. Cell viability was evaluated after 30, 60 and 90 days of re-growth. ...

Dielectric and field-dependent polarization response of palladium iodide nanoparticles under both in situ ex condition.

This paper presents a design method for AND-OR-EXOR three-level networks, where a single two-input exclusive-OR (EXOR) gate is used. The network realizes an EXOR of two sum-of-products expressions (EX-SOPs). The problem is to minimize the total number of products in the two sum-of-products expressions (SOPs). We introduce the notion of μ-equivalence of logic functions to develop exact minimizat...

Natural populations across a species range demonstrate population structure owing to neutral processes such as localized origins of mutations and migration limitations. Selection also acts on a subset of loci, contributing to local adaptation. An understanding of the genetic basis of adaptation to local environmental conditions is a fundamental goal in basic biological research. When applied to...
