Stochastic simulations as a tool for assessing signal fidelity in gene expression in synthetic promoter design
(Peer reviewed; Journal article, 2021-07)The design and development of synthetic biology applications in a workflow often involve connecting modular components. Whereas computer-aided design tools are picking up in synthetic biology as in other areas of engineering, ... -
Major bioactive chemical compounds in Astragali Radix samples from different vendors vary greatly
(Peer reviewed; Journal article, 2021-07)The worldwide traditional Chinese medicine (TCM) herbs sales figures have increased considerably to 50 billion US$ (2018). Astragali Radix (AR) is amongst the most often sold TCM herbs; sales in the European Union (EU) ... -
Development of tacrine clusters as positively cooperative systems for the inhibition of acetylcholinesterase
(Peer reviewed; Journal article, 2021-07)The synthesis of four tetra-tacrine clusters where the tacrine binding units are attached to a central scaffold via linkers of variable lengths is described. The multivalent inhibition potencies for the tacrine clusters ... -
Antiscaling Evaluation and Quantum Chemical Studies of Nitrogen-Free Organophosphorus Compounds for Oilfield Scale Management
(Peer reviewed; Journal article, 2021-08)Nonpolymeric aminomethylenephosphonates are widely used as powerful scale inhibitors in the petroleum industry. However, most of these inhibitors have certain drawbacks, such as low biodegradability and incompatibilities ... -
Toward Separation and Characterization of Asphaltene Acid and Base Fractions
(Peer reviewed; Journal article, 2021-08)Chemical inhibition of asphaltene deposition is considered a cost-effective way to prevent the harsh consequences of asphaltene instability in the produced crude. Thus, a careful screening of asphaltene inhibitors is crucial ... -
Comparative study on two deployment methods for large subsea spools
(Peer reviewed; Journal article, 2021-08)The demand for subsea spool deployment is increasing with the expansion of offshore projects. For a project to install multiple spools, different deployment methods can be used. The choice of method may influence the safety ... -
Thermochemical splitting of CO2 using solution combustion synthesized lanthanum–strontium–manganese perovskites
(Peer reviewed; Journal article, 2021-09)Redox reactivity of La(1-x)SrxMnO3 (LSM) perovskites towards a solar thermochemical CO2 splitting (CS) cycle is investigated. The LSM perovskites are synthesized via a solution combustion synthesis (SCS) method using glycine ... -
Photodegradable antimicrobial agents - synthesis, photodegradation, and biological evaluation
(Peer reviewed; Journal article, 2021-09)Multi-drug resistant (MDR) bacteria are already a significant health-care problem and are making the combat of infections quite challenging. Here we report the synthesis of several new compounds containing an ethanolamine ... -
Field test investigation of the performance of corrosion inhibitors: a case study
