Many monumental breakthroughs in p -type PbTe thermoelectrics are driven by optimizing a Pb 0.98 Na 0.02 Te matrix. However, recent works found that x > 0.02 in Pb 1– x Na x Te further improves the thermoelectric figure of merit, zT, despite being above the expected Na solubility limit. We explain the origins of impro…
Polymeric nanoparticles are one of the most studied strategies in modern medicine for drug encapsulation. The researchers' main interest is a formulation capable of administering the medication in a controlled mode and specific site. In this context, stimulus-responsive nanoparticles are highlighted, as these systems…
Sepsis is an aberrant systemic inflammatory response mediated by excessive production of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Developing an efficient antioxidant therapy for sepsis via scavenging ROS and RNS remains a big challenge owing to the insufficient activity and sustainability of…
Abstract Hydrogen is an ideal energy carrier in future applications due to clean byproducts and high efficiency. However, many challenges remain in the application of hydrogen, including hydrogen production, delivery, storage and conversion. In terms of hydrogen storage, two compression modes (mechanical and non-mecha…
Photothermal therapy (PTT), an emerging tumor treatment technology, has attracted tremendous interest, but excessive heat will cause damage to surrounding healthy tissues. Therefore, in situ temperature monitoring during PTT is of great importance to determine optimal treatment temperature and repair heat-damaged norm…
Abstract Optical transparency is an important property for a material, especially in certain fields like packaging, glazing, and displays. Existing commercial transparent polymeric materials are mostly amorphous. Semicrystalline polymers have often‐superior chemical resistance and mechanical properties particularly at…
CO 2 hydrogenation to methanol has attracted increasing attention with the development of renewable hydrogen. A big challenge is to identify catalysts able to achieve high conversion and selectivity. Here, we report an In 2 O 3 -supported Au catalyst that exhibits excellent performance for hydrogenation of CO 2 select…
Conspectus Nature evolves fascinating molecular pores to achieve unique biological functions based on a single pore or channel as observed for aquaporins and ion channels. An artificial system, on the other hand, explores porous structures to construct dense pores in materials. Progress in chemistry over the past cent…
Stabilizing monolayer nitrides with silicon Transition metal carbides and nitrides are nonlayered materials that in monolayer form have potentially useful electronic and chemical properties. These monolayers are usually made by chemical etching that produces flakes with surface defects that have poor air and water sta…
Deep\neutectic solvents (DESs) are new-generation media that can\nbe fine-tuned to have desired properties circumventing economic and\nenvironmental issues. Typically, these are ionic, and only recently,\nnonionic DESs, having interesting properties, are being explored.\nIn this report, we examined the structure and d…
We\nemploy a fine-tuned theoretical framework, combining ab initio molecular dynamics (AIMD), density functional\ntheory (DFT), and time-dependent (TD) DFT methods, to investigate\nthe interactions and optical properties of the iodoplumbates within\nthe low coordinative γ-butyrolactone (GBL) solvent environment,\nwide…
Flexible\nmetal–organic frameworks (MOFs) exhibit a variety\nof phenomena attractive for basic and applied science. DUT-49(Cu)\nis one of the remarkable representatives of such MOFs, where phase\ntransitions are coupled to pressure amplification and “negative\ngas adsorption”. In this work we report important insight…
The casting is the process of manufacturing in which the metal is brought in the liquid state and poured into the mold cavity then allowed to solidify. It takes the shape required for the particular material. Now a days research have been reached to a step where the demand of the complex properties are required under…

This article proposes a theoretically substantiated graph analytical method for studying the bearing capacity of orthotropic shell structures of minimum mass. A conceptually new approach to the analysis of optimization processes is considered. It is a rejection of the deterministic approach when exact initial data are…
O hidroximetilfurfural (HMF) é uma molécula plataforma (building block) a partir da qual é possível sintetizar uma grande variedade de compostos de elevado valor agregado, como por exemplo o 2,5-ácido furanodicarboxílico, monômero precursor do bioplástico, que é capaz de substituir o polímero polietileno tereftalato (…
Photodynamic therapy is based on the administration of a photosensitizing substance under light activation through the emission of an appropriate wavelength in the presence of molecular oxygen. Photochemical and photophysical reactions trigger the destruction of irradiated tissue, either by cell injury or vascular inj…
Background: Strategies aimed at inhibiting the expression of the c-myc oncogene could provide the basis for alternative cancer treatment. In this regard, silencing c-myc expression using small interfering RNA (siRNA) is an attractive option. However, the development of a clinically viable, siRNA-based, c-myc silencing…
This file contains global data enabling the replication of Table 1 in Locke et al. (2019). This is a .CSV file with estimates for each global grid cell (DGG cell) in the Three Global Conditions Map. The statistics in Table 1 can be estimated by summarizing these data across all grid cells. To use these data in a GIS,…
