Wearable tensile strain sensors have aroused substantial attention on account of their exciting applications in rebuilding tactile inputs of human and intelligent robots. Conventional such devices, however, face the dilemma of both sensitive response to pressure and bending stimulations, and poor breathability for wearing comfort. In this paper, a breathable, pressure and bending insensitive strain sensor is reported, which presents fascinating properties including high sensitivity and remarkable linearity (gauge factor of 49.5 in strain 0-100%, R 2 = 99.5%), wide sensing range (up to 200%), as well as superior permeability to moisture, air, and water vapor. On the other hand, it exhibits negligible response to wide-range pressure (0-100 kPa) and bending (0-75%) inputs. This work provides a new route for achieving wearing comfortable, high-performance, and anti-jamming strain sensors.

Introduction " photocatalyst is defined as a substance which is activated by adsorbing a photon and is capable of accelerating a reaction without being consumed [ ]. These substances are invariably semiconductors. Semiconducting oxide photocatalysts have been increasingly focused in recent years due to their potential applications in solar energy conversion and environmental purification. Semiconductor heterogeneous photocatalysis has enormous potential to treat organic contaminants in water and air. This process is known as advanced oxidation process "OP and is suitable for the oxidation of a wide range of organic compounds. "mong "OPs, heterogeneous photocatalysis have been proven to be of interest due to its efficiency in degrading recalcitrant organic compounds. Developed in the s, heterogeneous photocatalytic oxidation has been given considerable attention and in the past two decades numerous studies have been carried out on the application of heterogeneous photocatalytic oxidation process with a view to decompose and mineralize recalcitrant organic compounds. It involves the acceleration of photoreaction in the presence of a semiconductor catalyst [ ]. Several semiconductors TiO , ZnO, Fe O , CdS, ZnS can act as photocatalysts but TiO has been most commonly studied due to its ability to break down organic pollutants and even achieve complete mineralization. Photocatalytic and hydrophilic properties of TiO makes it close to an ideal catalyst due to its high reactivity, reduced toxicity, chemical stability and lower costs [ ]. Fujishima and Honda [ ] pioneered the concept of titania photocatalysis also known as Honda-Fujishima effect . Their work showed the possibility of water splitting in a photoelectrochemical cell containing an inert cathode and rutile titania anode. The applications of titania photoelectrolysis has since been greatly focused in environmental applications including water and wastewater treatment. This chapter provides insight into the fundamentals of the TiO photocatalysis, discusses the effect of variables af-

Nanobiotechnology holds great potential in various regimes of life sciences. In this review, the potential applications of nanobiotechnology in various sectors of nanotechnologies, including nanomedicine and nanobiopharmaceuticals, are highlighted. To overcome the problems associated with drug delivery, nanotechnology has gained increasing interest in recent years. Nanosystems with different biological properties and compositions have been extensively investigated for drug delivery applications. Nanoparticles fabricated through various techniques have elevated therapeutic efficacy, provided stability to the drugs and proved capable of targeting the cells and controlled release inside the cell. Polymeric nanoparticles have shown increased development and usage in drug delivery as well as in diagnostics in recent decades.

This review sums up recent developments in the syntheses, anti-inflammatory activities, and structure–activity relationship (SAR) studies of pyrimidine derivatives.

Difficult-to-access chiral primary amines were formed in good to high yield and ee using a rare example of a one-pot synthesis from prochiral ketones (sequential reductive amination-hydrogenloysis). As a highlight we also demonstrate a one-pot reductive amination-hydrogenolysis-reductive amination (five reactions) of ortho-methoxyacetophenone resulting in the chiral diamine 1-(2-methoxy-A C H T U N G T R E N N U N G phenyl)ethyl-(2-pyridylmethyl)-amine (4) (58% overall yield, > 99% ee), a new organocatalyst for aqueous enantioselective aldol reactions.

Recycling the waste for environmental protection has been an important challenge for the mankind. The fibrous waste in textile industry accounts for approximately 15% of the amount of fibers used, leading to a lower yield %. The current study focused to use this waste as reinforcement to produce a fiber-reinforced polymer composites. Reinforcements were woven in 3/1 S twill, using yarn produced from noil waste and knitting waste in the weft direction. The weft yarn count, type of waste material and number of picks were the variables of study. Laminated composites were fabricated from these reinforcements and the mechanical properties (tensile, bending and impact) were compared to the conventional glass fiber composites. The specific mechanical properties of these composites were found comparable or less than that of glass fiber composites.
