Theoretical simulation of solid polymer electrolytes based on Poly(vinylidene f...
Miranda, Daniel; Barbosa, João C.; Gonçalves, Renato; Miranda, Francisco; Vilaça, João; Costa, Carlos Miguel; Lanceros-Méndez, SenentxuSolid polymer electrolyte composited by poly(vinylidene fluoride) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) has been optimized for solid-state lithium-ion batteries taking into account the LiTFSI concentration. Computer simulations of battery systems was used to evaluate the influence of LiTFSI concentration at different battery operation temperatures (278.15 K, and 353.15 K) and different dischar...
Epidemiology and Burden of Ventilator-Associated Pneumonia among adult intensiv...
Mergulhão, Paulo; Pereira, João Gonçalves; Fernandes, Antero Vale; Krystopchuk, Andriy; Ribeiro, João Miguel; Miranda, Daniel; Castro, HeloísaVentilator-associated pneumonia (VAP) is a prevailing nosocomial infection in critically ill patients requiring invasive mechanical ventilation (iMV). The impact of VAP is profound, adversely affecting patient outcomes and placing a significant burden on healthcare resources. This study assessed for the first time the contemporary VAP epidemiology in Portugal and its burden on the healthcare system and clinical...
Overview on theoretical simulations of lithium‐Ion batteries and their applicat...
Miranda, Daniel; Gonçalves, Renato Ferreira; Wuttke, Stefan; Costa, Carlos Miguel Silva; Lanceros-Méndez, S.For the proper design and evaluation of next-generation lithium-ion batteries, different physical-chemical scales have to be considered. Taking into account the electrochemical principles and methods that govern the different processes occurring in the battery, the present review describes the main theoretical electrochemical and thermal models that allow simulation of the performance of lithium-ion batteries, ...
Quality management practices to direct and control the accomplishment of projec...
Rocha, António; Romero, Fernando; Miranda, Daniel; Amorim, Marlene; Lima, Rui M.Projects create value and capabilities for organizations and beneficiaries of their outcomes and must be managed by implementing quality processes to assure an execution compliant with plans, activities, and applicable standards, and to accomplish the defined requirements and objectives in an efficient and effective manner. This study analyzed the frequency of use of quality management practices by companies wi...
Study of the compression behavior of functionally graded lattice for customized...
Veloso, Fernando; Miranda, Daniel; Morais, Pedro; Torres, Helena; Oliveira, Bruno; Correia-Pinto, Jorge; Pinho, AntónioDeformational plagiocephaly is a head deformity that occurs in newborns, treated in severe cases with helmets named cranial remodeling orthoses (CRO). Current CROs can fail to adapt to head growth, causing excessive pressure sores and other complications, and may lead to poor clinical results. In this work, we experimentally and numerically study the compressive behavior of a functionally graded lattice that ma...
Tunable narrowband excitonic Optical Tamm states enabled by a metal-free all-or...
Castillo, Miguel; Cunha, Diogo; Estévez-Varela, Carla; Miranda, Daniel; Pastoriza-Santos, Isabel; Núñez-Sánchez, Sara; Vasilevskiy, MikhailOptical Tamm states (OTS) are confined optical modes that can occur at the interface between two highly reflective structures. However, due to the strong reflectance required, their implementation with highly processable and metal-free flexible materials has proven challenging. Herein, we develop the first structure supporting OTS based only on organic polymeric materials, demonstrating a photonic platform base...
Dynamic changes of inflammatory markers and their effects on the prognosis of p...
Azevedo, Cátia; Milhazes Mar, Fernando; Rios, Guilherme; Ribeiro, Carla; Miranda, Daniel; Vilarinho, Sérgio; Dias, LuisIntroduction: The use of prognostic markers to decide the most appropriate therapies to perform in each case is assumed as one of the pillars of the approach to the patient with squamous cell carcinoma (SCC) of the hypopharynx and larynx. In addition to the clinical and pathological stage determined by the classification system TNM, there is evidence that the tumor-related systemic inflammatory response (SIR) h...
