Heterostructures comprise two or more different semiconducting materials stacked either as co-assemblies or self-sorted based on their dynamics of aggregates. However, self-sorting in heterostructures is rather significant in improving the short exciton diffusion length and charge separation. Despite small organic molecules being known for their self-sorting nature, macrocyclic are hitherto unknown owing to unrestrained assemblies from extended π-conjugated systems.

Tuning the properties of soy protein isolate-based adhesive using various sustainable additives.

Int J Biol Macromol

January 2025

Department of Chemical, Metallurgical and Materials Engineering (Polymer Division), Institute of NanoEngineering Research (INER), Tshwane University of Technology, Pretoria, South Africa.

This work investigates the adhesive property of Soy Protein Isolate (SPI) polymer solution by studying mechanical properties of composites formed using waste wood granules and SPI solutions. To improve the adhesive strength of SPI solution, Carboxymethyl Cellulose Sodium (NaCMC) was mixed (in the weight ratios of 9:1 and 8:2) due to its strong gel formation capabilities. The adhesive performance of these composites was further investigated in the presence and absence of non-toxic additives, including sorbitol (SOR) and stearic acid (SA).

Article Synopsis
  • Mycobacterium tuberculosis (Mtb) modifies its metabolism to thrive in host cells, focusing on the protein Rv0547c, which targets the mitochondria of host cells.
  • Rv0547c enhances mitochondrial membrane fluidity and respiratory capacity, independent of its predicted targeting sequence, by influencing lipid composition and fatty acid metabolism.
  • The study demonstrates that Rv0547c increases Mtb's persistence during macrophage infection and helps the bacteria survive under stressful conditions by optimizing mitochondrial functions.

Breast cancer is the second most frequent cancer among women. Out of various subtypes, triple-negative breast cancers (TNBCs) account for 15% of breast cancers and exhibit more aggressive characteristics as well as a worse prognosis due to their proclivity for metastatic progression and limited therapeutic strategies. It has been demonstrated that AMP-activated protein kinase (AMPK) has context-specific protumorigenic implications in breast cancer cells.

Article Synopsis
  • The text discusses how structural similarities in organic molecules lead to narcissistic self-sorted phenomena, enhancing exciton dissociation and charge separation in solar cells.
  • It presents two π-conjugated derivatives, one being a zinc-porphyrin linked to benzothiadiazole (PB) as the acceptor and anthracene (PA) as the donor, which form unique 1D nanofibers and aggregates.
  • The study highlights that the electrical properties of these self-sorting assemblies are influenced by the electrostatic potential differences between PA and PB, achieving a conductivity of 0.14 S cm, which aids in the development of more effective photovoltaic materials.

Cerebral ischemic stroke is one of the foremost global causes of death and disability. Due to inadequate knowledge in its sequential disease mechanisms, therapeutic efforts to mitigate acute ischemia-induced brain injury are limited. Recent studies have implicated epigenetic mechanisms, mostly histone lysine acetylation/deacetylation, in ischemia-induced neural damage and death.

Silver nanoparticles (AgNPs) have been widely utilized in various biomedical and antimicrobial technologies, displaying broad-spectrum activities against Gram-negative and Gram-positive bacteria including multidrug-resistant strains. However, the emergence of resistance to AgNPs upon repeated exposure and the survival of bacteria after initial exposure to antimicrobial agents pose a threat, as they may lead to the development of new resistant populations. To combat the early stages of antibacterial resistance, systematic analysis is essential to understand the immediate response of bacteria to antimicrobial agents.

Control over the dimensionality of stimulated organic semiconductors has aroused significant interest in organic electronics; however, the design of such materials still remains to be decided. Herein, we have developed three dibenzothiophene-appended freebase, zinc-metalated and copper-metalated porphyrin derivatives (PFb-DBT, PZn-DBT and PCu-DBT) in which PCu-DBT leads to an anion-binding complex in chloroform upon the application of light, resulting in self-assembled 1D nanostructures with high electrical conductivity. Nevertheless, light-stimulated freebase and zinc-metalated P-DBT undergo protonation and demetalation.

Department of Electronic Science and Technology, College of Electronic Information and Optical Engineering, Nankai University, Tianjin 300350, China.

Colloidal all-inorganic CsPbI perovskite quantum dots (PQDs) have shown tremendous potential in photovoltaic applications in recent years due to their outstanding optoelectronic properties that general metal halide perovskites offer, along with the added advantages that originates from size reduction and the quantum confinement effect. However, the issue of low carrier mobility in PQD films caused by insulating organic ligands capped on the PQD surface still remains to be addressed while aiming for high-efficiency PQD solar cells. Herein, we propose a novel strategy that takes benefits of ionic liquids, which can offer the high polarity and the electron donating ability to boost the mobility of PQD films in photovoltaic devices.
