1.Characterisation and properties of homo- and heterogenously phosphorylated nanocellulose.
Kokol V1, Bo?i? M2, Vogrin?i? R2, Mathew AP3. Carbohydr Polym. 2015 Jul 10;125:301-13. doi: 10.1016/j.carbpol.2015.02.056. Epub 2015 Mar 12.
Nano-sized cellulose ester derivatives having phosphoryl side groups were synthesised by phosphorylation of nanofibrilated cellulose (NFC) and nanocrystaline cellulose (NCC), using different heterogeneous (in water) and homogeneous (in molten urea) processes with phosphoric acid as phosphoryl donor. The phosphorylation mechanism, efficacy, stability, as well as its influence on the NC crystallinity and thermal properties, were evaluated using ATR-FTIR and (13)C NMR spectroscopies, potentiometric titration, capillary electrophoresis, X-ray diffraction, colorimetry, thermogravimmetry and SEM. Phosphorylation under both processes created dibasic phosphate and monobasic tautomeric phosphite groups at C6 and C3 positioned hydroxyls of cellulose, yielded 60-fold (∼1,173 mmol/kg) and 2-fold (∼1.038 mmol/kg) higher surface charge density for p-NFC and p-NCC, respectively, under homogenous conditions. None of the phosphorylations affected neither the NC crystallinity degree nor the structure, and noticeably preventing the derivatives from weight loss during the pyrolysis process.

2.The hydrolysis kinetics of monobasic and dibasic aminoalkyl esters of ketorolac.
Qandil AM1, Jamhawi NM, Tashtoush BM, Al-Ajlouni AM, Idkaidek NM, Obaidat AA. Drug Dev Ind Pharm. 2013 Sep;39(9):1346-56. doi: 10.3109/03639045.2012.712535. Epub 2012 Sep 20.
Six aminoethyl and aminobutyl esters of ketorolac containing 1-methylpiperazine (MPE and MPB), N-acetylpiperazine (APE and APB) or morpholine (ME and MB), were synthesized and their hydrolysis kinetics were studied. The hydrolysis was studied at pH 1 to 9 (for MPE, APE and ME) and pH 1 to 8 (for MPB, APB and MB) in aqueous phosphate buffer (0.16 M) with ionic strength (0.5 M) at 37°C. Calculation of k(obs), construction of the pH-rate profiles and determination of the rate equations were performed using KaleidaGraph® 4.1. The hydrolysis displays pseudo-first order kinetics and the pH-rate profiles shows that the aminobutyl esters, MPE, APB and MB, are the most stable. The hydrolysis of the ethyl esters MPE, APE and ME, depending on the pH, is either fast and catalyzed by the hydroxide anion or slow and uncatalyzed for the diprotonated, monoprotonated and nonprotonated forms. The hydrolysis of the butyl esters showed a similar profile, albeit it was also catalyzed by hydronium cation.

3.Characteristic properties of water-soluble cutting fluids additives for iron materials.
Watanabe S1. J Oleo Sci. 2007;56(8):385-97.
This review article describes preparations and properties of various types of water-soluble cutting fluids additives derived from various materials. It is concerned with synthetic additives classified according to their functional groups: carboxylic acids, esters, dibasic acids, ethers, amides, substituted fatty acids and others for iron materials. Testing methods for water-soluble cutting fluids are described on ways for laboratory and practical tests for factory.

4.Sucrose esters with various hydrophilic-lipophilic properties: novel controlled release agents for oral drug delivery matrix tablets prepared by direct compaction.
Chansanroj K1, Betz G. Acta Biomater. 2010 Aug;6(8):3101-9. doi: 10.1016/j.actbio.2010.01.044. Epub 2010 Feb 2.
Sucrose esters (SE) are esters of sucrose and fatty acids with various hydrophilic-lipophilic properties which have attracted interest from being used in pharmaceutical applications. This study aimed to gain insight into the use of SE as controlled release agents for direct compacted matrix tablets. The study focused on the effect of hydrophilic-lipophilic properties on tableting properties and drug release. Sucrose stearate with hydrophilic-lipophilic balance (HLB) values ranging from 0 to 16 was systematically tested. Tablet formulations contained SE, metoprolol tartrate as a highly soluble model drug and dibasic calcium phosphate dihydrate as a tablet formulation filler in the ratio 1:1:2. The compaction behaviour of matrix tablets was compared with the compacts of individual starting materials as reference. SE incorporation improved the plasticity, compressibility and lubricating property of powder mixtures. The hydrophilic-lipophilic properties of SE affected tableting properties, drug release rate and release mechanism.
