It is with great sadness for us that Professor Wei Jiang, a young and well-known supramolecular chemist, passed away on Sunday25 December 2022. He created a series of supramolecular hosts including Oxatubarenes [1] and Naphthotubes [2] with inner functionalized groups [3–6] and applied them into materials, catalysis,molecular machines and drug recognition and delivery fields [7–10] during his independent research career.

The micromechanical behavior of (CoCrNi) 94 Al 3 Ti 3 medium-entropy alloy (MEA) with and without Al 2 O 3 nanoparticles was investigated by nanoindentation, microhardness, and microscratch tests. Adding Al 2 O 3 nanoparticles in the (CoCrNi) 94 Al 3 Ti 3 MEA increases elastic modulus, hardness, brittleness, and friction coefficient. The MEAs with and without Al 2 O 3 exhibit indentation-induced pile-up, resulting in the inapplicability of the Oliver & Pharr method. The elastic modulus and indentation hardness were assessed by the work-based approach. Indentation size effect is observed for the MEA, but is absent with the addition of Al 2 O 3 nanoparticles.

Metal-semiconductor nanocomposites have emerged as a viable strategy for concurrently tailoring both thermal and electronic transport properties of established thermoelectric materials, ultimately achieving synergistic performance. In this investigation, a series of nanocomposite thin films were synthesized, embedding metallic cobalt telluride (CoTe2) nanophase within the nanocrystalline ternary skutterudite (Co(Ge1.22Sb0.22)Te1.58 or CGST) matrix. Our approach harnessed composition fluctuation-induced phase separation and in situ growth during thermal annealing to seamlessly integrate the metallic phase. The distinctive band structures of both materials have developed an ohmic-type contact characteristic at the interface, which raised carrier density considerably yet negligibly affected the mobility counterpart, leading to a substantial improvement in electrical conductivity. The intricate balance in transport properties is further influenced by the metallic CoTe2 phase’s role in diminishing lattice thermal conductivity. The presence of the metallic phase instigates enhanced phonon scattering at the interface boundaries. Consequently, a 2-fold enhancement in the thermoelectric figure of merit (zT ∼ 1.30) is attained with CGST-7 wt. % CoTe2 nanocomposite film at 655 K compared to that of pristine CGST. © 2024 The Authors.

Surface ligand engineering of perovskite quantum dots for n-type and stretchable photosynaptic transistor with an ultralow energy consumption

The escalating demand for high-speed transmission has prompted an exploration into the development of photonic synapses, offering a promising avenue for extending energy-efficient, low data latency in neurologically inspired robotics and neuromorphic network computation. However, the performance of n-type conjugated polymers (CPs)-based transistors with intrinsic stretchability as photonic synapse devices for neuromorphic simulation has been suboptimal. This study introduces a series of surface ligands for perovskite quantum dots (PeQDs) with varying chain lengths and bulkiness of quaternary ammonium bromide to adjust interactions with the n-type CPs, naphthalene-diimide-bithiophene (PNDI2T). The results demonstrate that didodecyldimethylammonium bromide (DDAB) reveals superior defect passivation and optimal ligand bulkiness, enhancing interaction and energy transmission between CPs and PeQDs. Through surface ligand engineering of PeQDs, the PNDI2T/DDAB-QD composite effectively emulates characteristics of photonic synapses under multiwavelength light stimuli and strain;it achieves outstanding performance metrics, comprising the fastest response time (1 ms), highest current contrast (3.2 × 106), paired-pulse facilitation (1.97), ultralow energy consumption (0.16 aJ), and human learning behaviors at an ultralow operating voltage of 50 mV under a 50 % tensile strain. Concisely, leveraging surface ligand engineering of PeQDs proposes a promising strategy for advancing neurologically soft optoelectronics and neuromorphic computation. © 2024 Elsevier B.V.

Nickle-cobalt alloy nanocrystals inhibit activation of inflammasomes

Activation of inflammasomes—immune system receptor sensor complexes that selectively activate inflammatory responses—has been associated with diverse human diseases, and many nanomedicine studies have reported that structurally and chemically diverse inorganic nanomaterials cause excessive inflammasome activation. Here, in stark contrast to reports of other inorganic nanomaterials, we find that nickel-cobalt alloy magnetic nanocrystals(NiCo NCs) actually inhibit activation of NLRP3, NLRC4 and AIM2 inflammasomes. We show that NiCo NCs disrupt the canonical inflammasome ASC speck formation process by downregulating the lncRNA Neat1, and experimentally confirm that the entry of NiCo NCs into cells is required for the observed inhibition of inflammasome activation. Furthermore, we find that NiCo NCs inhibit neutrophil recruitment in an acute peritonitis mouse model and relieve symptoms in a colitis mouse model, again by inhibiting inflammasome activation. Beyond demonstrating a highly surprising and apparently therapeutic impact for an inorganic nanomaterial on inflammatory responses, our work suggests that nickel-and cobalt-containing nanomaterials may offer an opportunity to design anti-inflammatory nanomedicines for the therapeutics of macrophage-mediated diseases.
