Paper workers

In two papers workers at Varian Associates Analytical Instrument Division, describe several methods for increasing the effective resolution of n.m.r. instruments (at the expense of decreased signal-noise ratio). All of the methods are illustrated by reference to the case of... 

Considerable activity is underway to develop nontoxic activator and accelerator systems for these room temperature curing reactive adhesives. It is of interest to note that progress in analogous systems has been made in dental research - in work on acrylic adhesives for repair and for acrylic dentures. In one of several papers ( ), workers describe compositions of complex, exotic acrylic monomers cured with standard and modified Schiff s bases and with complex aromatic amines.

In an extensive series of papers, workers at Nankai University in Ghina have detailed the synthesis of disilyl and digermyl-bridged " " complexes 187. These rearrange to the isomeric non-metal-metal bonded complexes 188 upon extended thermolysis in xylene via an intramolecular process which results in the cleavage of both Fe-Fe and E-E (E = Si, Ge) bonds and formation of two new Fe-E bonds (Equation (21)).

Some mention should be made of perhaps the major topic of conversation among surface and colloid chemists during the period 1966-1973. Some initial observations were made by Shereshefsky and co-workers on the vapor pressure of water in small capillaries (anomalously low) [119] but especially by Fedyakin in 1962, followed closely by a series of papers by I>eijaguin and co-workers (see Ref. 120 for a detailed bibliography up to 1970-1971). 

The heat of adsorption is an important experimental quantity. The heat evolution with each of successive admissions of adsorbate vapor may be measured directly by means of a calorimeter described by Beebe and co-workers [31]. Alternatively, the heat of immersion in liquid adsorbate of adsorbent having various amounts preadsorbed on it may be determined. The difference between any two values is related to the integral heat of adsorption (see Section X-3A) between the two degrees of coverage. See Refs. 32 and 33 for experimental papers in this area. 

The VER lifetime of liquid O2 is 280 ms at 70 K [82]. Predicting such a slow rate from theory is a fonnidable challenge taken up by Skinner and co-workers [54] in a recent paper. The fundamental frequency of O2 is 1552... 

HCR and co-workers carried out a number of studies by employing 3D potential energy surfaces calculated by means of highly sophisticated ab initio approaches [88,91-101]. The results of these computations are in impressive agreement with the corresponding experimental findings. The discrepancies in the order of 100 wavenumbers, as in early ab initio studies [16,17], have been reduced in the HCR studies to only a few wavenumbers. In conclusion of their paper on the ( H ) system of NH2, Gabriel et al. state We believe... 

When the adsorbent has been introduced into the tube, the latter is fitted into a filter flask (see Fig. 77, 46, 2) to which a pump is attached the pump is run slowly and the column is again pressed down gently with the wooden pestle. The circumference of the upper surface is gently and uniformly tapped, especially where it is in contact with the glass surface, for about one minute air bubbles and channels are thus avoided when the solution is poured in. Some workers place a loose plug of cotton wool or a circle of filter paper at the top of the column in order to protect the solid from disturbance when the liquid is introduced. 

It has been necessary to comment upon these various studies because Olah and his co-workers have suggested that whilst nitrations, like those with nitronium salts, which give a relative rate of reaction of toluene with respect to benzene not much greater than unity involve the nitronium ion as the electrophile, this is not so in other cases. It is important to consider these opinions closely. In the earlier of the two relevant papers it is agreed that since nitrations of toluene with nitronium tetrafluoroborate in sulpholan show no abnormal o -ratio there... 

The first three of a series of papers by Ridd and co-workers on Inductive and Field effects in Aromatic Substitution have appeared. Results of studies of the nitration of 4-phenylp5nidine and of 4-benzylpyridine in aqueous sulphuric acid were reported and use of the usual criteria (para 8.2) showed that in each case the conjugate acid was the species undergoing nitration. The values of where fm refers to the corresponding homocyclic compound (biphenyl or diphenylmethane) when plotted against r, the distance between the...
