Slow-release cross-coupling and an advanced method for β-glycosylation: methods stimulated by amphotericin B
… identified under which MIDA boronates could be slowly hydrolyzed in the SMC reaction, enabling an in situ “slow-release” of the boronic acid. This slow release effect enables the efficient cross-coupling of a variety of otherwise unstable boronic acids. The synthesis and isolation of 2-pyridyl …

Promoting material circularity in pulp and paper mills: organic-inorganic cellulosic composites for slow-release of nutrients
… challenges with commercial fertilisers. Slow/controlled-release fertilisers (SCRFs) offer an opportunity to repurpose waste-stream materials and improve nutrient retention in forests. The aim of this study was to evaluate the potential of transforming pulp and paper waste components into …

Safety of Slow Release Lipopolysaccharide (LPS) Pellet in a Swine Model and Development of an Exogenous Reference Control for Real Time PCR
<p>Natural induction modes of chronic inflammation associated with obesity (CIAO) are difficult to characterize and even more difficult to replicate in humans due to interand intra-variation in individuals and initiating conditions. Variables that can influence resistance to the development of CIAO …

Study of Ion-Transport and Release from Carboxymethyl Cellulose and other Polymer Networks
… on the soil as well as on the crops. The rapid release of nutrients from fertilizers not only prevents crops from properly absorbing them, but also destroys the quality of the soil, while unabsorbed nutrients damage our environment through the hydrological cycle. Slow-release fertilizers have …

Topical Antimicrobial and Bandaging Effects on Equine Distal Limb Wound Healing
… bandaged (SSD-B), 1.0 % silver sulfadiazine slow release matrix bandaged (SDX-B), 1.0% silver sulfadiazine slow release matrix not bandaged (SDX-NB), povidone-iodine ointment bandaged (PI-B), untreated control bandaged (C-B) and untreated control not bandaged (C-NB) until healing. Wound area, …

Nitrogen availability and pine seedling growth in organically- amended mine soils
… 3) 112 Mg/ha sawdust + fertilizer + 336 kg/ha slow-release N, and 4-7) lime-treated municipal sewage sludge at rates of 22, 56, 112, and 224 Mg/ha. Nitrogen availability after 40 mo (as determined by aerobic and anaerobic incubations) in sawdust- and sludge-amended soils was two to 20 times …

Detecting exploitable stages in the life history of koi carp (Cyprinus carpio) in New Zealand
… bacterial infection on transmitter expulsion, a slow-release antibiotic was tested to improve transmitter retention. Dummy acoustic transmitters were implanted in two groups of 20 adult koi carp, an untreated control group, and a group treated with a slow-release, single-dose antibiotic. After …

Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
… to mitigate soil water loss, as a matrix for the slow-release of fertiliser, and for UV-vis light blocking to retain water, limit nutrient loss and prevent weed growth, respectively. However, microplastics remaining from poorly biodegradable mulch films, and the release of typical mulch film …

The modification of Laponite® with silver or copper and investigation of their antibacterial activity
… at 24 hours. To access the persistency and slow release of the antibacterial agents the release profile was compared with AgNO3 and CuSO4. While all the silver-Laponite® RD and copper-Laponite® RD showed slow and consistent release over the whole investigation period, AgNO3 and CuSO4 were …

Synthesis and biological studies of a fullerene-Taxol conjugate and fullerene-based transfection vectors
… the development of a new application of C60 as a slow-release system for the liposome aerosol delivery of lipophilic chemotherapeutics to lung cancer. TaxolRTM (paclitaxel), one of the most active anticancer drugs in clinical use, has shown significant potential for treatment of lung cancer when …

Synthesis and characterisation of amides based on crown ether supramolecular gels
… due to their potential applications as hosts in slow-release drug delivery, tissue engineering, sensing, crystallising media, catalysis etc. The understanding of gel structure and the self-assembly process are challenging because the structure and properties rely mostly on the geometry of the …

Synthesis of zeolites and their application as soil amendments to increase crop yield and potentially act as controlled release fertilizers.
… growth, their cation exchange capacity (CEC) and slow-release fertilizer properties. Most work on slow-release fertilizers has focused on natural Clinoptilolite, Phillipsite and Chabazite. The aim of this study was to synthesize zeolites, study their effectiveness as soil amendments and their …

Application of graphene based composites in agriculture
… to address these problems are based on designing slow-release fertilizers using porous materials or polymer-coating of conventional fertilizers, which have seen some success but are severely limited by their cost. Graphene (GN) and its derivatives may offer a path-way to develop more efficient …

Cytochrome C Oxidation by the Bacterial Photosynthetic Reaction Center From Rhodobacter Sphaeroides
… strength, RC turnover is rate-limited by the slow release of the bound reaction product, photooxidized cytochrome. Double flash studies confirm the basic result, but also suggest that slower parallel pathways of electron transfer from the soluble cytochrome pool may exist that circumvent the …

A Comparative Study of Composted Organic Wastes and IBDU Fertilizer in Nitrogen Utilization by Bentgrass Cultivars
… absorption efficiency in relation to an organic slow release fertilizer. Western's compost facility supplied the two different organic wastes, which had been composted for 1 year. The materials used were composted urban leaf litter, sawdust/manure mixture at a 50/50 ratio by volume and an organic …
