“…Subsequently, due to the heavy atom effect, electrons are transferred to the triplet excited state (T 1 ) via intersystem crossing (ISC), instead of decaying back to the ground state (S 0 ). [39] These long-lived triplet excitons are expected to migrate and participate in hydrogen evolution reactions. The considerably prolonged triplet lifetime of Pd-MOF (62 μs) in comparison to Pt-MOF (4 μs) provides a significantly expanded window for electrons to interact with H + , thereby enhancing the facilitation of H 2 production.…”

In this report, a 2D MOF nanosheet derived Pd single‐atom catalyst, denoted as Pd‐MOF, was fabricated and examined for visible light photocatalytic hydrogen evolution reaction (HER). This Pd‐MOF can provide a remarkable photocatalytic activity (a H2 production rate of 21.3 mmol/gh in the visible range), which outperforms recently reported Pt‐MOFs (with a H2 production rate of 6.6 mmol/gh) with similar noble metal loading. Notably, this high efficiency of Pd‐MOF is not due to different chemical environment of the metal center, nor by changes in the spectral light absorption. The higher performance of the Pd‐MOF in comparison to the analogue Pt‐MOF is attributed to the longer lifetime of the photogenerated electron‐hole pairs and higher charge transfer efficiency.

“…Biopolymers have several advantages over synthetic polymers, which are commonly used in biomedical applications 4 . Synthetic polymers are derived from petrochemicals, and their degradation can release toxic byproducts into the environment 5 .

Polysaccharides are a class of natural biopolymers that have attracted significant attention due to their unique properties, which make them attractive for use in a wide range of applications. These biopolymers have an important role in our daily life, and designing biomaterials for biomedical applications requires careful consideration of factors such as biocompatibility, biodegradability, renewability, affordability, and availability, all of which can be achieved with polysaccharides. This review paper focuses on the use of polysaccharides in biomedical applications and provides an in‐depth analysis of the potential applications of arabinoxylan, a type of hemicellulose, in various fields, including drug delivery, infection control, tissue engineering, wound healing, and others. Arabinoxylan, which is derived from plants, is the most abundant and important class of hemicellulose and has a diverse role as a catalyst due to its biodegradability, biocompatibility, and renewable nature. Polysaccharide‐based biopolymers have applications in tissue engineering, wound covers, drug delivery systems, food preservation, and biocomposite films, making them an emerging excipient in pharmaceutical research. This review paper highlights the potential of polysaccharide‐based biopolymers in biomedical science and suggests that continued research and development will lead to broader and more innovative applications in the field. The use of polysaccharide‐based biopolymers has the potential to significantly advance healthcare and improve patient outcomes.

Characterising Hydroxyapatite Deposited from Solution onto Novel Substrates: Growth Mechanism and Physical Properties

Whilst titanium, stainless steel, and cobalt-chrome alloys are the most common materials for use in orthopaedic implant devices, there are significant advantages in moving to alternative non-metallic substrates. Substrates such as polymers may have advantageous mechanical biological properties whilst other substrates may bring unique capability. A key challenge in the use of non-metal products is producing substrates which can be modified to allow the formation of well-adhered hydroxyapatite films which promote osteointegration and have other beneficial properties. In this work, we aim to develop methodology for the growth of hydroxyapatite films on surfaces other than bulk metallic parts using a wet chemical coating process, and we provide a detailed characterisation of the coatings. In this study, hydroxyapatite is grown from saturated solutions onto thin titanium films and silicon substrates and compared to results from titanium alloy substrates. The coating process efficacy is shown to be dependent on substrate roughness, hydrophilicity, and activation. The mechanism of the hydroxyapatite growth is investigated in terms of initial attachment and morphological development using SEM and XPS analysis. XPS analysis reveals the exact chemical state of the hydroxyapatite compositional elements of Ca, P, and O. The characterisation of grown hydroxyapatite layers by XRD reveals that the hydroxyapatite forms from amorphous phases, displaying preferential crystal growth along the [002] direction, with TEM imagery confirming polycrystalline pockets amid an amorphous matrix. SEM-EDX and FTIR confirmed the presence of hydroxyapatite phases through elemental atomic weight percentages and bond assignment. All data are collated and reviewed for the different substrates. The results demonstrate that once hydroxyapatite seeds, it crystallises in the same manner as bulk titanium whether that be on a titanium or silicon substrate. These data suggest that a range of substrates may be coated using this facile hydroxyapatite deposition technique, just broadening the choice of substrate for a particular function.
