Utilizing a photolabile ligand as MOF strut can make a framework undergo full or partial decomposition upon irradiation. For the first time, a nitrophenylacetate derivative has been incorporated into MOF as a backbone linker via PLSE method. The photo-induced decarboxylation of the NPDAC-MOF represents a novel way of degrading a MOF, which provides an innovative approach to formulating photoresponsive porous materials with potential applications in molecular release and drug delivery. When photoactive linker is mixed with non-photolabile linker via partial PLSE, the MOF structure can be retained after irradiation, but with the introduction of multiple defects, offering a new method to create vacancies in MOFs. Defect repair can be achieved by treatment with replacement ligands, the scope of which is an interesting area for developing customizable MOF contents.<br>

Definite Time

Ammonia can be recovered from soil with an efficiency of 98·5 to 99·5 per cent, in six hours in the apparatus described.For most purposes it is sufficient to aerate the soil for three hours.Highly dunged glasshouse soils undergo partial decomposition in the cold with magnesia. In such cases the soil should be aerated with magnesia and strong sodium chloride solution for a definite time, say three hours.The complete recovery of added ammonia from a calcareous soil is difficult unless the soil is finely ground.

Passage To The Limit

A new method of partial decomposition of a domain is proposed for partial differential equations, depending on a small parameter. It is based on the information about the structure of the asymptotic solution in different parts of the domain. The principal idea of the method is to extract the subdomain of singular behavior of the solution and to simplify the problem in the subdomain of regular behavior of the solution. The special interface conditions are imposed on the common boundary of these partially decomposed subdomains. If, for example, the domain depends on the small parameter and some parts of the domain change their dimension after the passage to the limit, then the proposed method reduces the initial problem to the system of equations posed in the domains of different dimensions with the special interface conditions.

Abstract Three methods have been discussed which have been successfully used for the degradation of vulcanizates for infrared analysis: pyrolysis between 450 and 600°C, degradation in 1,2-dichlorobenzene, and incomplete degradation at 200°C. Because of the relatively low cost, pyrolysis is generally used for the identification of single elastomers, but this method is less suited to blends where it may lead to the loss of ir bands characteristic of a certain component, e.g. polybutadiene. It is similarly unsuited when polymers which form mostly gaseous components are present in small amounts. Since it cannot be excluded in the analysis of vulcanizates of unknown composition, it is recommended to confirm the identification by partial decomposition at 200°C. Because of its greater cost, degradation in 1,2-dichlorobenzene is preferred only for vulcanizates containing small proportions of thermally stable rubbers. When one operates in this way, it is safe to assume that no polymer components will be missed which constitute more than 20 wt % of a rubber blend. Below this limit, identification depends greatly on the components of the blend.
