Compounds containing carbon−boron bonds serve as valuable intermediates for constructing more complex molecules by transforming these bonds into other carbon−element bonds. The catalytic dehydrogenative borylation of carbon−hydrogen bonds using HBpin presents an appealing method for synthesizing carbon−boron bonds. While this approach has been extensively explored with noble metals for various types

We demonstrate how Al(III) interactions with a ‘biomimetic’ model homo-peptide, polyaspartic (pAsp), with a narrow size distribution (around 20 amino acids monomer units), can lead to substantially different outcomes by governing Al(III) hydrolysis/phase separation. The addition of unhydrolysed Al(III) in aqueous peptide solutions results in dominant pAsp20 destabilisation and precipitation from the

Renewable electricity-driven seawater electrolysis for hydrogen production offers substantial potential for sustainable energy solutions. However, the high concentration of chloride ions (Cl−) in seawater triggers competitive chemical reactions and severe corrosion, posing a challenge to the durability of the anode. In this study, we present a hexafluoroantimonate-intercalated NiFe layered double hydroxide

Zinc is both essential and toxic to microorganisms including pathogenic bacteria. To harness the antimicrobial activity of Zn, use of a suitable Zn ionophore is necessary to facilitate its penetration of the bacterial cell membrane. On the other hand, 5-chloro-8-hydroxyquinoline, also known as cloxyquin, has known antibacterial, anti-fungal and anti-protozoal activity and can act as a Zn ionophore

Micrometer-sized Niobium pentoxides (Nb2O5), with inherent safety and ability for fast lithium insertion/de-insertion, have been regarded as the promising anode for high-volumetric-energy-density lithium-ion batteries (LIBs). However, they suffer from structural instability and capacity fading in practical application. To address these issues, we adopt a Ta doping strategy to change the chemical composition

Owing to their vibrant chromatic representation and distinctive optical characteristics, stimuli-responsive multicolor luminescent materials have attracted heightened interest within the domains of information security and intelligent systems. Nonetheless, developing phosphors that exhibit stimuli responsiveness, especially those with luminescence influenced by both temperature variations and excitation

Single-crystal-to-single-crystal (SCSC) transformation materials are of great research interest because of their promising applications, among which multifunctional switching as next-generation intelligent materials in photoelectric devices is rare, and the corresponding mechanism remains unclear.

In this study, a step-by-step synthesis strategy was adopted to successfully construct three-dimensional hierarchical porous architectures by first epitaxially growing vertically oriented NiCoMo hydroxide nanosheet arrays on Ti3C2Tx MXene substrates via a ligand-modulated hydrothermal method. The NiCoMoS-Ti3C2Tx heterostructures with strong interfacial coupling are then obtained through interface engineering

Sonodynamic therapy (SDT) offers distinct advantages for deep tumor ablation due to its excellent tissue penetration ability and demonstrates significant preclinical and clinical potential.

In this study, we designed an iridium(III) complex to evaluate its

Supramolecular self-assembly is a promising tool to develop multifunctional theranostic agents and has recently entered the field of radiochemistry. In this work, lantern-shaped [Pd2L4]4+ metallacages featuring a blood-brain barrier-penetrating peptide were designed for dual-modality imaging. Two silicon-based fluoride acceptors were incorporated in the cage ligand for radiolabeling with Fluorine‑18

Though immunogenic cell death (ICD) has garnered signifi-cant attention in the realm of “cold” tumor therapies, effectively stimulating strong immune responses with minimal side effects and their real-time monitoring in deep-seated tumors remains challenging. There is no available drug that covers these two bases with one swing. Herein, we report a rationally designed and synthesized first class of

Cancer persists as a principal cause of global mortality. Despite significant progress in cancer therapeutics in recent decades, chemotherapy remains a primary modality for cancer treatment. Based on their mechanism of action, commonly used chemotherapeutic agents can be classified into several categories, including Topoisomerase inhibitors.
