Complex vigorous fabrics - explosive fill and propellants - are a serious expertise for nationwide safety. whereas numerous new promising thoughts and formulations have emerged lately, the dep. of security is worried in regards to the nation's skill to take care of and increase the information base during this quarter. to help in addressing those issues, places of work inside of DOD requested the NRC to enquire and determine the scope and well-being of the U.S. R&D efforts in lively fabrics. This document presents that overview. It provides a number of findings in regards to the present R&D attempt and suggestions geared toward bettering U.S. functions in constructing new lively fabrics know-how. This research reviewed U.S. learn and improvement in complicated energetics being carried out through DoD, the DoE nationwide laboratories, industries, and academia, from a listing supplied by way of the sponsors. It additionally: reviewed papers and know-how tests of non-U.S. paintings in complicated energetics, assessed very important parameters, akin to validity, viability, and the chance that every of those fabrics could be produced in volume; pointed out obstacles to scale-up and creation, and advised technical methods for addressing strength difficulties; and, urged particular possibilities, thoughts, and priorities for presidency sponsorship of applied sciences and production strategy improvement.

On a Farther Shore: The Life and Legacy of Rachel Carson, Author of Silent Spring

Released at the 50th anniversary of her seminal ebook, Silent Spring, here's an indelible new portrait of Rachel Carson, founding father of the environmental movement

Rachel Carson begun paintings on Silent Spring within the past due Fifties, while a dizzying array of artificial insecticides had come into use. top this chemical onslaught was once the insecticide DDT, whose inventor had gained a Nobel Prize for its discovery. potent opposed to crop pests in addition to bugs that transmitted human illnesses corresponding to typhus and malaria, DDT had firstly seemed secure. yet as its use multiplied, alarming experiences surfaced of collateral harm to fish, birds, and different flora and fauna. Silent Spring was once a chilling indictment of DDT and its results, which have been lasting, frequent, and lethal.

Published in 1962, Silent Spring stunned the general public and compelled the govt to take action-despite a withering assault on Carson from the chemical substances undefined. The ebook woke up the realm to the heedless infection of our surroundings and finally ended in the institution of the EPA and to the banning of DDT and a bunch of comparable insecticides. via drawing scary parallels among risky chemical compounds and the then-pervasive fallout from nuclear checking out, Carson opened a fault line among the mild excellent of conservation and the extra pressing new thought of environmentalism.

Elegantly written and meticulously researched, On a Farther Shore unearths a shy but passionate girl extra at domestic within the flora and fauna than within the literary person who embraced her. William Souder additionally writes sensitively of Carson's romantic friendship with Dorothy Freeman, and of her loss of life from melanoma in 1964. This amazing new biography captures the essence of 1 of the good reformers of the 20 th century.

Japan at Nature's Edge: The Environmental Context of a Global Power

Japan at Nature's part is a well timed number of essays that explores the connection among Japan's background, tradition, and actual atmosphere. It significantly expands the point of interest of earlier paintings on jap modernization through analyzing Japan's position in international environmental transformation and the way jap principles have formed our bodies and landscapes over the centuries.


Here's an unique and interesting new consultant to a couple of the main inhospitable locations in the world. incredible, full-color images of the folk who reside within the barren region, and the creatures and vegetation that continue to exist the extremes of temperature, provide a different "eyewitness" view of this adverse surroundings. See the beautiful sand dunes of the Namib barren region, a Bedouin in complete marriage ceremony gown, the desolate tract in bloom, a jewel wasp and a camel's regalia.

Mother Nature: Popular Culture and Environmental Ethics

This short yet bold booklet explores our courting with nature during the imagery we use after we discuss mom Nature. making use of the severe instruments of spiritual reviews, psychology, and gender reports, Catherine M. Roach examines some of the manifestations of nature as "mother" and what that suggestion implies for how we technique the flora and fauna.

He was part of the Chemistry Division, Research Department, for many years, as a research chemist (1973-1980), branch head of the Energetic Materials Branch (1980-1985), and head of the Chemistry Division (19851989).

Military in Afghanistan was widely reported by the news media. " Early reports claimed that these energetic materials provide vastly increased performance relative to conventional high explosives. These claims appear to be based on anecdotal evidence from selected tests rather than on scientifically rigorous data. J. Bartlett, University of Florida. 2002. Presentation to the committee.

By contrast, the high surface area (104 to 106 times that of the particles used in traditional formulations) and the short diffusion length of nanoscale particles are expected to enhance the role of chemical kinetics. Consequently, an unprecedented degree of control of the energy release rate may be possible by varying the composition on the nanodimensional scale. The burning rate might be accelerated, the delivered specific impulse could be increased by improved combustion efficiency, and the detonation might achieve greater ideality.
