According to news originating from Braga, Portuga l, by NewsRx correspondents, research stated, "Antifouling compounds are used as paint components to mitigate biofouling on ships and submerged structures. One of the most known and used antifouling compounds is tributyltin (TBT)." Financial support for this research came from North Portugal Regional Operationa l Pro-gramme (ON.2 - O Novo Norte) , under the National Strategic Reference Fram ework (NSRF) , through the European Regional Development Fund (ERDF). Our news journalists obtained a quote from the research from the University of M inho, "However, TBT is toxic to aquatic living beings, causing problems such as reduction of growth and imposex. The development of a TBT chemosensor could be o f utter relevance in the building of an in-situ TBT monitoring device. Therefore , this work reports the synthesis of five new quinoline-based hydrazones (HZ) an d two new quinoline-based thiosemicarbazones (TSC), with synthesis yields from 1 7 to 83 %. The compounds were tested in the presence of TBT, and so me compounds of the group showed colorimetric or fluorimetric changes. The inter action between these compounds and TBT was tested by spectrophotometric or spect rofluorimetric titrations, which allowed to calculate the limit of detection (LO D) for each interaction. The fluorimetric interaction between HZ 4a and TBT was shown to be the most sensitive chemosensory method, with a LOD value of 1.7 mu M . A Ridge classifier model was developed to correlate the ability for TBT detect ion and the modification of the structure of each molecule. The validity of the proposed model was tested by assessing the TBT-sensing ability of the two novel TSC 5a and 5b, which were synthesized after the development of the model. These two compounds also showed colorimetric changes in the presence of TBT, with LODs of 13.8 and 3.1 mu M, respectively, in good accordance with the model's predict ions."

According to news reporting originating from Shenyang, People's Republic of China, by NewsRx correspondents, research stated, "A novel integral sliding mode control (ISMC) strategy combined with an adaptive super twisting observer ( ASTO) for an uncertain robotic manipulator tracking control system is presented in this article. The comprehensive uncertainties including both parameter pertur bations and external disturbances are considered during the controller design." Financial support for this research came from National Natural Science Foundatio n of China (NSFC). Our news editors obtained a quote from the research from Northeastern University , "Firstly, a new nominal control law with prescribed time convergent property b ased on time varying scaling function is presented for the system without uncert ainties. Then this nominal control law constitutes the prescribed time convergen t sliding surface for ISMC. As the reaching phase is eliminated in ISMC, leading to the prescribed time stability of the whole control system without uncertaint ies. Secondly, take the system uncertainties (both the matched and unmatched unc ertainties) into consideration, two ASTOs are designed for handling them. So, th e lumped uncertainties of the robotic manipulator control system can be well est imated and compensated in finite time with the help of backstepping method. Besi des, the finite time convergent adaptive switching gains of the ASTO make the sy stem stable without knowing the bounds of the uncertainties exactly and suppress the chattering phenomenon of control input. Finally, the proposed control algor ithm is validated by simulation and experiment on a robotic manipulator."
